Structure Design And Experimental Verification Of Ultra Thin Parallel Flow Condenser For Vehilcle

At present,with the automotive industry to improve energy saving and environmental protection requirements,the entire automotive air conditioning system products are moving in the direction of high efficiency,light weight and energy saving.As the core component of the air conditioning system,the condenser is also so,the literature can be seen that the parallel flow condenser is the most suitable replacement model for R134 a,and it is the development direction of high efficiency,miniaturization,light weight and low cost.The existing parallel flow condenser specifications are 22,20,16 mm and 12 mm,but the current 12 mm of the parallel flow condenser unit area of heat exchange with the 16 mm thickness of the condenser decreased a lot.Compact car structure,hope that the space as small as possible,while also required to reduce the weight.This study based on the actual needs,through on condenser performance and structural analysis to determine the new condenser should meet the structure,performance and reliability requirements,and based on the requirements design the new condenser structure and use the experimental method to determine the new condenser key performance parameters and manufacturing process parameters.Finally,through the methods of test verified the products amplified the feasibility of mass production.This research developed the 12 mm thin parallel flow condenser weight ratio of the original 16 mm parallel to the flow of the weight of the condenser reduced by 15.7%,the refrigerant charge volume decreased by 17.2%,reducing the body weight while also reducing the cost,improve the market competitiveness of the car,has a strong market competitiveness and application prospects.
