To solve the match problem of multi-heat-exchangers module for vehicle cooling system,an extensive experimental investigation about the effectiveness of various distances between heat exchangers on module performance was carried out on the wind tunnel facilities.The first row of test module was charge air cooler(CAC) and hydraulic oil cooler(HOC),the second row was radiator,and the third is transmission oil cooler(TOC).The distance between each row of the first test module was 0 mm,the second was 100 mm,and...
