Heat exchanger e.g. subcooling-type condenser, for air-conditioning circuit of motor vehicle, has collector boxes including walls defining heat exchange paths, where path reduction between successive paths is defined by specific formula

摘要

The exchanger has a bundle of heat exchanging tubes (6) received at an end in collector boxes (2, 4), where the tubes extend from a side of the collector box (2) to a side of the collector box (4). The collector boxes include walls (10a-10e) defining heat exchange paths (P1-P6) of the exchanger, where path reduction between successive paths is defined by specific formula having parameters representing number (N) of paths comprising between 2 to 8.
