heat exchanger

摘要

The heat exchanger includes a collector (18) with holes (22), an end chamber to cover the collector and a bundle of tubes (12) with ends (16) fitted in the collector holes. The tube ends have a widening (26) projecting on the end chamber side, on which there is a molded diversion plate (40). This plate has apertures (46) opposite the holes in the collector, with a widened edge (48) to widen the tube to reduce loss of pressure.
