摘 要
通過對隔熱車廂結(jié)構(gòu)及尺寸的分析比較，完成冷藏車車廂總成設(shè)計(jì)，其中包括車廂設(shè)計(jì)、車廂對開門設(shè)計(jì)及性能計(jì)算與校核。
本設(shè)計(jì)的隔熱車廂各部分之間的連接多采用粘接劑而非螺栓和鉚釘?shù)冉饘偌?，不僅減少了熱橋，而且增加了平整度和美觀度。隔熱材料選用應(yīng)用最廣泛的聚氨酯泡沫，其導(dǎo)熱系數(shù)較小且具有一定的抗拉抗彎強(qiáng)度，與鋼板和膠合板的粘接力較強(qiáng)且密度低，減少了隔熱壁厚度，在車廂外尺寸確定的情況下增大了車廂裝載容積。車廂門及其附件盡量采用簡單可靠的零部件和裝配固定方法，確保密封性。根據(jù)計(jì)算確定的熱工參數(shù)選用合適的制冷機(jī)組并合理完成各部分的安裝與固定。
本設(shè)計(jì)的車廂總成結(jié)構(gòu)簡單，性能良好，成本不高，高性能材料和先進(jìn)技術(shù)的應(yīng)用有效降低了車廂的自重，各參數(shù)均符合設(shè)計(jì)要求。

ABSTRACT
This paper completed the assemble design of the compartment of the refrigerated truck including the carriage design, the open door design, the performance calculation and verification through analysis and comparison the structure and the size of the insulated compartment.
In this design, the connection between the parts mostly use adhesive rather than rivets, bolts and other metal pieces, which not only reduced the thermal bridge, but also increases the level and degree of beauty. The most extensive application of polyurethane foam is selected for insulation material which not only has small coefficient of thermal conductivity, but also has certain tensile strength and bend strength. The polyurethane foam has excellent adhesive force with the armor plate and the plywood. And the density is low which reduces the thickness of the insulated wall. So when the compartment has fixed external size the stowage volume of the compartment is increased. The door and its accessories as much as possibly use a simple and reliable parts and assembly method to ensure the seal. We should choose a appropriate refrigeration unit according to calculating the parameter of the heat engineering and complete the installation and fixed of various parts reasonably.
This design of the compartment assemble has simple structure, good performance, low cost and the usage of high-performance materials and advanced technology which reduce the compartment’s weight. All parameters in this design are in line with the design requirements.
KEY WORDS: refrigerated and insulated car, insulation material, refrigeration unit, heat transfer coefficient
