发明名称 METHOD FOR MAKING HEAT EXCHANGER HAVING AT LEAST TWO COLLECTING PIPES
摘要 A heat exchanger has two collecting pipes and a streamlined-section tube matrix connected with these two pipes. The collecting pipes comprise several thin sheet metal shells connected with one another which permits simplified and higher speed manufacture of the collecting pipes, particularly since manufacture of cutouts in the collecting pipes for fitting through the small streamlined-section tubes, which is otherwise very time-consuming, can be significantly simplified.
