ABSTRACT

 
The topic of this design is the modification design of Jianghuai refrigerated automobiles. Refrigerated automobile is used heat insulation carriage as insulation device, makes use of different cooling device, therefore, implementes perishable goods on transportation from a certain degree .
After consulting relevant information, analyzing the contrast of the development status of refrigerator automobiles at home and abroad, I put forward the purpose and significance of this design ,at the meanwhile,develop the content of this graduation design.
This design conducts the design of the overall layout of vehicle the design of the choice of second type chassis and insulation carriage,the design of refrigerating system and subframe, carrys on the design and calculation of all the vehicle performance ,based on the features of refrigerated automobile.In various parts of the design calculations, firstly, I introduce the principle,after comparison,conduct theoretical anlysis calculations and check, in accordance with the principle of selection for the first design.The design of the final selection of cars fill with insulation material for rigid polyurethane,and non-stand-alone refrigeration as cold plate refrigeration, so that vehicle performances excellent.
From the theoretical calculation of the design ,the refrigerated automobile is in the good performance,and it achieves to the national standard. In theory, the design is feasible.
