摘要

The heat exchanger making process involves assembling tubes (11) into a tube bundle (12), and fitting collector boxes (13, 14) at the ends and fins (15) in between. The tubes are first joined together with the collector boxes and soldered to each other, and after this, the fins are inserted into the intermediate regions, after which they too are soldered.
