年世界發(fā)生石油危機(jī)以來(lái)，加上環(huán)境污染的加劇，節(jié)能問(wèn)題日益引起了人們的重視。如何提高能源的利用率，減少船舶柴油機(jī)廢氣的排放，保護(hù)人類賴以生存的環(huán)境是許多人致力研究的課題。就燃料大戶船舶而言，目前柴油機(jī)余熱的利用主要是利用廢氣渦輪增壓器將廢氣能量轉(zhuǎn)換成掃氣空氣的壓力來(lái)提高柴油機(jī)的功率和效率，同時(shí)利用廢氣鍋爐產(chǎn)生 0.5MPa 左右的飽和水蒸汽來(lái)滿足船員的日常生活用水及油艙的加熱保溫等，卻忽略了柴油機(jī)冷卻水帶走了大量熱量這一事實(shí)。這使得廢熱的利用不僅不充分，而且不合理。在船舶朝著大型化、高速化發(fā)展的今天，柴油機(jī)的額定功率最大的已超過(guò)37285KW，為減少耗油，柴油機(jī)冷卻水的出口溫度也從20世紀(jì)60

我國(guó)現(xiàn)階段狀況：熱電是可逆的，熱電發(fā)電和半導(dǎo)體冷卻是熱電現(xiàn)象的兩個(gè)方面，相互可逆。 一般是PN結(jié)，假設(shè)溫差可以用來(lái)發(fā)電，若是電源，可以在一端使用冷。半導(dǎo)體制冷和使用具有一定的程度，已經(jīng)有商業(yè)設(shè)施和發(fā)售，然而溫差發(fā)電, 這幾乎是一個(gè)空白。這是因?yàn)槲覈?guó)在軍事高科技研發(fā)能力相對(duì)落后?，F(xiàn)階段隨著何種學(xué)術(shù)互補(bǔ)，我國(guó)許多學(xué)者對(duì)外接觸相干技術(shù)，在以后的發(fā)展中，這種情況一定會(huì)逐漸改善。 余熱發(fā)電的前提是利用余熱發(fā)生器，他是將熱電材料產(chǎn)生的熱電效應(yīng)轉(zhuǎn)化為電流。包括塞貝克效應(yīng)，珀耳帖效應(yīng)和湯姆森效應(yīng)。這三個(gè)因素與開(kāi)爾文關(guān)系：有關(guān)，如圖所示：該裝置的結(jié)構(gòu)與傳統(tǒng)的跨平面型微電子冷卻裝置的結(jié)構(gòu)相同。交叉平面微電子冷卻裝置的原理與傳統(tǒng)的熱電冷卻裝置的原理非常相似，除了基板和熱電偶臂本體成為薄膜材料之外，由于在這種冰箱構(gòu)造中，熱流的導(dǎo)向和基板其表面是如此垂直所謂的。雙層基板是連接到冷端和發(fā)電機(jī)的熱端的熱電偶。其原理是：根據(jù)塞貝克效應(yīng)，當(dāng)發(fā)電機(jī)的冷熱端溫度差時(shí)，電路會(huì)產(chǎn)生電流。他使用厚膜Bi2Te3合金材料，同時(shí)保持熱電臂的橫截面積和長(zhǎng)度比相同的條件，減少熱電吊臂，增加每單位體積密度的熱功率。同時(shí)，微電子發(fā)電裝置連接數(shù)萬(wàn)個(gè)熱電偶，在低溫差下獲得電壓高電壓，這種微電熱發(fā)電裝置的另一個(gè)特點(diǎn)是其制造工藝結(jié)合了電化學(xué)沉積和集成電路蝕刻工藝。測(cè)試裝置由2300個(gè)熱電偶組成，熱電臂的長(zhǎng)度為50m，直徑為6m。 在8.5K的溫差下，可以在4.1V的電壓下提供22mw的功率。 試驗(yàn)表明，上述所用可用于MEMS，提供微功率。 目前，JPL正在研發(fā)使用P型和N型Bi2T3，納米線替代厚膜合金，便用相似的措施完成更小尺寸的半導(dǎo)體電偶臂。當(dāng)然發(fā)電器的構(gòu)造還有很多，然而就目前的選取的幾種上述結(jié)果證明，微卷熱電轉(zhuǎn)換器的熱損失較小，熱能利用率較高，但微加工愈加艱巨。同時(shí)，因?yàn)闊犭姴牧显跍囟忍荻确较蛏蠟榇?lián)，所以熱電材料的溫度差不是很大，所以發(fā)電量也很小。薄膜熱電發(fā)電程序從來(lái)說(shuō)微處理技術(shù)相對(duì)成熟，其尺寸相對(duì)較小。但是由一般低功率產(chǎn)生的功率，僅有微瓦熱電堆PN結(jié)相對(duì)于溫度場(chǎng)是一個(gè)并聯(lián)結(jié)構(gòu)，每對(duì)PN結(jié)具備一樣的溫差，所以每對(duì)PN結(jié)串聯(lián)，功率較大，另外，熱源腔最好設(shè)計(jì)得相對(duì)大一點(diǎn)，這樣燃料燃燒，溫度掌控等比較容易，然而熱損失比微型線圈發(fā)電機(jī)要大。在這里用熱電堆式熱電發(fā)生器作為熱電電源的重要部件來(lái)設(shè)計(jì)。二、余熱發(fā)電模塊設(shè)計(jì)熱電堆型微電熱發(fā)電機(jī)主要包括上，下熱罩，分流芯片，焊料層，PN結(jié)懸臂和輸出線等部件。 微電子發(fā)電機(jī)的輸出功率和效率會(huì)被接觸電阻影響，湯姆遜效應(yīng)和溫度波動(dòng)的影響以及熱覆蓋片，導(dǎo)流板和焊料層對(duì)熱導(dǎo)率的影響。熱電發(fā)電器模塊的設(shè)計(jì)有水流道、氣流道和熱電發(fā)電偶臂的構(gòu)造設(shè)計(jì)。設(shè)計(jì)這個(gè)模塊的形態(tài)要注意熱量的最大利用。余熱發(fā)電器模塊設(shè)計(jì)通常有，微卷式SwissRoll，熱電堆和薄膜熱發(fā)電，在這三者之間進(jìn)行比較發(fā)現(xiàn)，微卷式雖然熱量損失小，但是加工很復(fù)雜，沒(méi)有條件不便使用。薄膜熱發(fā)電的處理技術(shù)相對(duì)不成熟，而且功率很低，不宜進(jìn)行試驗(yàn)。PN節(jié)和溫度場(chǎng)的熱電堆并聯(lián)，每對(duì)PN結(jié)溫差相同，所以每對(duì)PN結(jié)串聯(lián)，發(fā)電功率較大，最終采用熱電堆熱電，發(fā)電機(jī)作為火力發(fā)電的部件來(lái)設(shè)計(jì)。為達(dá)到最大熱量的利用，所以我想到了“雙管形熱電發(fā)電器”和“方形熱電發(fā)電器”，雙管形熱電發(fā)電器的熱量利用率比方形熱電發(fā)電器要高，但其應(yīng)用中制作方面要求較高而且維修不方便，方形熱電發(fā)電器不但具有較高的熱利用率，并且后期用于制造方便，維修簡(jiǎn)單所以最后采用方形熱電發(fā)電器。下面我以簡(jiǎn)圖的形式來(lái)介紹一下方形熱電發(fā)電器電偶臂的具體組成：三、余熱發(fā)電器設(shè)計(jì) 發(fā)電機(jī)組主要有熱蓋基板，導(dǎo)流板和電臂三部分。 當(dāng)電臂端部之間的溫差，P，N結(jié)兩種不同的熱電材料會(huì)產(chǎn)生Seebeck（Seebeck）效應(yīng)，所以電路中有電流。 PN電動(dòng)臂式熱電發(fā)電機(jī)在通風(fēng)管與水管之間， PN熱電偶熱電發(fā)電機(jī)有電絕緣熱套，引流銅和PN電臂，熱蓋95的氧化鋁陶瓷， 導(dǎo)電層材料為銅板，焊料層為75和95的錫和導(dǎo)電銀塑料和高溫銀漿。 電臂材料為Bi2Se3，熱電發(fā)電機(jī)電臂橫截面尺寸為3mm3mm，高16.4mm，電臂對(duì)對(duì)199對(duì)。 從以往的理論分析可以看出，熱電材料的選擇賽貝克越高，質(zhì)量越好。四、余熱發(fā)電器的工藝設(shè)計(jì)熱電發(fā)電機(jī)電臂橫截面尺寸大多為1mm2以上，粒徑較大，熱電材料切割比較容易。 PN結(jié)臂放在陣列的專用的模具中，用手動(dòng)方法，總的加工相對(duì)容易。流程圖如圖321?，F(xiàn)具體闡述如下：在用導(dǎo)向?qū)犹幚硖沾苫逯?，接下?lái)是生產(chǎn)電臂。 因?yàn)殡妱?dòng)臂的尺寸小，材料脆性好，所以這里是一個(gè)硅模工藝，也就是先制成一個(gè)正方形的正方形的硅模陣列，再放入熔融的熱電材料中，并將發(fā)電機(jī)覆蓋的基板，再去除原有的硅模，留下熱電電偶臂。 詳細(xì)的硅模工藝如下：按照熱電發(fā)生器的設(shè)計(jì)，制造光刻膠曝光用掩模膜。使用厚度為0.3mm0.5mm的拋光硅晶片，尺寸為8.“蕩滌硅晶片，用氫氟酸緩沖液作為蝕刻溶液除去二氧化硅的外表，并在涂層上放置一層光機(jī)器光致抗蝕劑的厚度約為50微米。曝光顯影后，光致抗蝕劑在硅晶片的表面上形成方孔陣列，再經(jīng)過(guò)深度光刻，硅晶片形成方孔陣列，形成方孔陣列不是一個(gè)通孔，而是一個(gè)方形凹槽陣列。然后去除硅片上的光刻膠。兩片晶片，涂在光致抗蝕劑的另一面，重復(fù)曝光顯影，光刻，清洗等。方槽的另一面在方槽兩側(cè)形成的陣列排列成一列。這時(shí)要求在高溫爐中需要硅模，將P型和N型半導(dǎo)體懸臂材料放在石英容器r用于高溫加熱和加熱直到熔融溫度為約650。然后，將P型熱電材料注入硅模側(cè)面上的方形槽中，并且在硅模具冷卻之后，固化了硅模，將硅模翻轉(zhuǎn)，將N型熱電材料注入到模具的另一側(cè)。再通過(guò)行硅模冷卻，熱電材料固化。結(jié)束時(shí)在硅片兩面研磨直到露出熱電偶，并按照需求的熱電偶高度，確定研磨和研磨的量經(jīng)過(guò)模具的厚度電臂和焊接層的接合，發(fā)電機(jī)切割封裝，要求得到熱電發(fā)生器。 用圖形來(lái)體現(xiàn)。整個(gè)工藝有涂膠、曝光顯影、光刻、鑄模以及鍵合封裝等工藝，主要應(yīng)用了硅模和電偶臂的制造工藝。 圖3-21pn電偶臂五、總結(jié)

of Waste Heat Recovery Device for Marine EngineIn todays society, waste heat has become a kind of environmental pollution and waste of resources phenomenon, this paper mainly designed the marine engine exhaust waste heat recovery device, that is, waste heat power generation system model.This paper mainly introduces the design scheme of the waste heat power generation system model. The main principle is that the thermal energy is converted into electric energy by the temperature difference between the two power generation components. The main component consists of a cold source and a heat source, a micro-generator. It is characterized by the use of convenience, high quality, harmless to the environment, while saving energy.The theoretical basis of the system model for the waste heat generator system is based on the Thomson effect.Key words: waste heat utilization, waste heat power generation model, Thomson effect1.Waste heat generation theoryAt present in the microelectronic generator research, the theory of foreign microelectronic generators is representative of Princeton University, University of Southern California and University of Michigan. Most of the research results in the United States have focused on the use of waste heat in Japans military, aerospace, practice and high-tech aspects of the application of thermoelectric generating units. Chinas current situation: thermoelectric is reversible, thermoelectric power generation and semiconductor cooling is the thermoelectric phenomenon of two aspects, mutual reversible. Usually PN junction, assuming that the temperature difference can be used to generate electricity, if the power supply, you can use cold at one end Semiconductor refrigeration and use has a certain degree, there are already commercial facilities and sale, but the thermoelectric power generation, which is almost a blank. This is because our country in the military high-tech R & D capability is relatively backward. At this stage with what kind of academic complementarity, many scholars of our foreign contact with the relevant technology, in the future development, this situation will gradually improve.Waste heat power generation is the premise of the use of waste heat generator, he is the thermoelectric effect of thermoelectric materials into electricity. Including the Seebeck effect, the Peltier effect and the Thomson effect. These three factors relate to Kelvin: as shown in the figure:The structure of the device is the same as that of the conventional cross-planar microelectronic cooling device. The principle of the cross-planar microelectronic cooling device is very similar to that of the conventional thermoelectric cooling device. In addition to the substrate and the thermocouple arm body being a film material, since the heat flow is guided and the surface of the substrate is so vertical So-called. The double substrate is a thermocouple connected to the cold end and the hot end of the generator. The principle is: According to the Seebeck effect, when the generator hot and cold temperature difference, the circuit will produce current. He used thick film Bi2Te3 alloy material while maintaining the thermal power arm cross-sectional area and length ratio of the same conditions, reducing the thermoelectric boom, increasing the thermal power per unit volume density. At the same time, microelectronic power generation devices connected tens of thousands of thermocouples, low voltage difference in the voltage obtained under high voltage, this micro-electric power plant is another feature of its manufacturing process combines the electrochemical deposition and integrated circuit etching process. The test device consists of 2300 thermocouples with a length of 50 m and a diameter of 6 m. In the 8.5K temperature difference, can be 4.1V voltage to provide 22mw of power. Experiments show that the above can be used for MEMS, providing micropower. At present, JPL is developing the use of P-type and N-type Bi2T3, nanowires instead of thick film alloy, with similar measures to complete the smaller size of the semiconductor electric arm.Of course, there are many structures of the generator, but the current selection of several of the above results show that micro-roll thermoelectric converter heat loss is small, high thermal efficiency, but the micro-processing more difficult. At the same time, because the thermoelectric material in the direction of temperature gradient in series, so the thermoelectric material temperature difference is not great, so the power generation is also very small. Thin film thermoelectric power generation process has been relatively mature microprocessing technology, its size is relatively small. However, the power generated by the general low power, only the micro-tile pyroelectric PN junction relative to the temperature field is a parallel structure, each pair of PN junction with the same temperature difference, so each pair of PN junction in series, the power is large, in addition, the heat source cavity It is best to design a relatively large, so that fuel combustion, temperature control and other relatively easy, but the heat loss than the micro-coil generator to large. Where the thermopile thermoelectric generator is used as an important part of the thermoelectric power supply.2. Waste heat power generation module designThermopile-type micro-electric generator mainly includes upper and lower heat shield, shunt chip, solder layer, PN junction cantilever and output lines and other components. The output power and efficiency of the microelectronic generator are affected by the contact resistance, the influence of the Thomson effect and the temperature fluctuation, and the effect of the thermal cover sheet, the baffle plate and the solder layer on the thermal conductivity.The design of the thermoelectric generator module is the structural design of the water flow channel, the air flow path and the thermoelectric power generation arm. Design the form of this module should pay attention to the maximum use of heat.The design of the waste heat generator module is usually made by the micro-roll SwissRoll, the thermopile and the thin film thermal power generation, and the comparison between the three found that the micro-roll type, although the heat loss is small, but the processing is very complicated and there is no inconvenience to use. Thin film thermal power treatment technology is relatively immature, and the power is very low, should not be tested.PN junction and the temperature field of the thermopile in parallel, each pair of PN junction temperature difference is the same, so each pair of PN junction in series, generating power larger, the final use of thermopile thermoelectric, generators as a thermal power generation components to design. In order to achieve maximum heat utilization, so I think of the double-tube thermoelectric generator and square thermoelectric generator, double-tube thermoelectric generator heat utilization than the square thermoelectric generator to be high, but its production High demand and maintenance is not convenient, square thermoelectric generator not only has a high heat utilization, and later for manufacturing convenience, easy maintenance so the final use of square thermoelectric generator.Here I am in the form of a brief introduction to the square thermoelectric generator electric arm of the specific composition:3. Waste heat generator designThe main generating units are hot cover substrate, baffle and electric arm three parts. When the temperature difference between the ends of the boom, P, N knot two different thermoelectric materials will produce Seebeck (Seebeck) effect, so the circuit current.PN electric boom thermoelectric generator between the ventilation pipe and the water pipe, PN thermocouple thermoelectric generator with electrical insulation sets, copper and PN electric discharge, hot cover 95% alumina ceramic, conductive layer material for the copper, solder The layers are 75% and 95% tin and conductive silver plastic and high temperature silver paste. Electric arm material for the Bi2Se3, thermoelectric generator arm cross-sectional size of 3mm 3mm, 16.4mm high, the pair of pairs of pairs of electricity. From the previous theoretical analysis can be seen, the choice of thermoelectric materials, the higher the quality of Baker, the better the quality.4. Waste heat generator process designThermoelectric generator electric arm cross-sectional size of most of 1mm2 or more, larger particle size, thermoelectric material cutting easier. PN junction arm placed in the array of special mold, with manual method, the total processing is relatively easy. The flow chart is shown in Figure 3-21.Is specifically described as follows:After the ceramic substrate is treated with the guide layer, the arm is subsequently produced. Because the size of the electric arm is small, the material is brittle, so here is a silicon mold process, that is, first made of a square square silicon mold array, and then into the molten thermoelectric materials, and the generator covered substrate, And then remove the original silicon mold, leaving the thermocouple arm.The detailed silicon mold process is as follows: According to the thermoelectric generator design, the photoresist exposure mask film is manufactured. Using a polished silicon wafer with a thickness of 0.3 mm to 0.5 mm and a size of 8. The silicon wafer was washed with a hydrofluoric acid buffer as an etching solution to remove the appearance of the silica and a layer of light was placed on the coating The thickness of the resist is about 50 microns.When the exposure is developed, the photoresist forms a square hole array on the surface of the silicon wafer, and then undergoes deep lithography, the silicon wafer forms a square hole array, and the square hole array is not a pass Hole, but a square groove array. Then remove the photoresist on the silicon chip. Two wafers, coated on the other side of the photoresist, repeat exposure development, lithography, cleaning, etc. The other side of the square The p-type and N-type semiconductor cantilever materials are required to be placed in the quartz vessel r for high temperature heating and heating until the melting temperature is about 650 C. Then, a silicon mold is required in the high temperature furnace, , The P-type thermoelectric material is injected into the square groove on the side of the silicon mold, and after the silicon mold is cooled, the silicon mold is solidified, the silicon mold is inverted, the N-type thermoelectric material is injected into the other side of the mold, Mold cooling, thermoelectric The material is cured at the end of the wafer on both sides of the grinding until the thermocouple exposed, and in accordance with the requirements of the thermocouple height, to determine the amount of grinding and grinding through the thickness of the die arm and welding layer of the junction, the generator cutting package, Device.With graphics to reflect. The entire process of coating, exposure development, lithography, casting and bonding packaging and other technology, the main application of the silicon mold and electric arm manufacturing process.5. SummaryShip cabin is a large distributed energy system, as the ship power core of the host, the entire energy system is a reasonable distribution and effective use of the key. The host exhaust heat a large proportion of waste heat, and this part of the higher quality of waste heat, is the main source of waste heat utilization on board. In this paper, the heat utilization of the exhaust heat of the ship is analyzed, and the heat balance diagram of the waste heat is obtained. Based on the analysis of the conditions of waste heat, it is shown that there are still many difficulties in the utilization of low quality waste heat. This part of the waste heat of the new equipment will greatly improve the thermal economy of marine diesel engines.共 21 頁(yè) 第 1 頁(yè)指 導(dǎo) 教 師 評(píng) 語(yǔ) 外文翻譯成績(jī)：指導(dǎo)教師簽字： 年 月 日注：1. 指導(dǎo)教師對(duì)譯文進(jìn)行評(píng)閱時(shí)應(yīng)注意以下幾個(gè)方面：翻譯的外文文獻(xiàn)與畢業(yè)設(shè)計(jì)（論文）的主題是否高度相關(guān)，并作為外文參考文獻(xiàn)列入畢業(yè)設(shè)計(jì)（論文）的參考文獻(xiàn)；翻譯的外文文獻(xiàn)字?jǐn)?shù)是否達(dá)到規(guī)定數(shù)量（3 000字以上）；譯文語(yǔ)言是否準(zhǔn)確、通順、具有參考價(jià)值。2. 外文原文應(yīng)以附件的方式置于譯文之后。
