Heat exchange module especially for motor vehicle engine has manifold housing of main heat exchanger made with projecting comb to fasten fins

摘要

The heat exchange module consists of a main (1) and secondary (2) heat exchanger with housings equipped with fluid circulation tubes (22, 23), at least one manifold housing (5, 8) with a plate (35) having holes for the tubes, and cooling fins (11) common to both heat exchangers. The manifold housing of the main heat exchanger has at least one projecting comb (28) with cut-outs to receive the tubes of the secondary heat exchanger. The comb also locks the portions of fins projecting from the body of the main heat exchanger. In addition, the outer surface of the main heat exchanger manifold plate is equipped with a seal (33).
