Heat exchanger, particularly for use in motor vehicles

摘要

The heat exchanger (HE) comprises a plurality of flat panels (A, B) of tubes (1) each of which comprises a row of parallel tubes (1) of equal diameter, made of plastics material, and interconnected side by side. The panels (A, B) are interconnected in a stacked arrangement with a transverse relative offset substantially equal to the radius of a tube (1) so that the tubes (1) of one panel (A) extend in the recesses defined between adjacent tubes (1) of at least one neighbouring panel (B). <IMAGE>
