Aluminum-alloy heat exchanger

摘要

The heat exchanger has two tanks connected by finned heat transmission tubes where each tank comprises a seat plate (5), a tank main body (6) and two end plates (7) which assemble in a wafer-cake shaped manner through peripheral projections (17,18) engaging notches (12,15) and holes (16). The end plate projections which engage the notches have leading end portions which are deformed by pressing to hold the parts together during brazing. An independent claim is also included for a tank for an aluminum alloy heat exchanger.
