摘 要
随着改革开放的不断深入,经济建设和人民生活对冷藏汽车的需求越来越来迫切,使用的覆盖面越来越来广泛,需求量也越来越来大。方便灵活的冷藏汽车在我国冷藏运输中扮演了越来越重要的角色。冷藏保温汽车是冷藏运输用的专用汽车,用来运输易腐货物和对温度有特殊要求的货物。本设计以一汽解放悍威J5M汽车二类底盘为基础,改装设计为大型冷藏汽车,该车冷藏箱通过焊接安装在副车架上。冷藏车厢既有隔热保温作用,又安装有制冷机组制冷,满足冷藏车的冷藏温度-4℃的设计要求。运输途中压缩机通过皮带由发动机驱动。

ABSTRACT
With the continuous deepening of reform and opening up, economic construction and people's growing demand for refrigerated vehicles to pressing to use more and more extensive coverage, demand is also growing to large. Convenient and flexible in our refrigerated transport refrigerated vehicles play an increasingly important role. Refrigerated vehicles are used in special refrigerated transport vehicles used to transport perishable goods and have special requirements on the temperature of the goods. The design FAW Hanwei J5M two types of chassis-based vehicles, modified design for large refrigerated cars, car refrigerator mounted by welding on the subframe. The role of both thermal insulation cold storage compartment, and a refrigeration unit installed refrigeration, refrigerated trucks to meet the temperature of -4 ℃ refrigeration design requirements. Transit through the belt by the engine-driven compressor.
