Abstract
A heat exchanger (10) of a heat exchange device used for air cooling cold water units or commercial roof machines, a method for manufacturing the heat exchanger (10), a heat exchange module, a heat exchange device, and a heat source unit. The heat exchanger (10) comprises: a main body portion (ab); a bent portion (cd) with a trapezoid cross section, the bent portion (cd) and the main body portion (ab) being connected and approximately perpendicular to each other; two collecting pipes (11, 12), disposed on two opposite sides of the heat exchanger (10); and multiple heat exchange pipes (13), each extending from one collecting pipe (11) of the two collecting pipes (11, 12) to the other collecting pipe (12) by passing through the main body portion (ab) and the bent portion (cd), wherein a top edge of the bent portion (cd) and a top edge of the main body portion (ab) of the heat exchanger (10) are approximately located at the same height level.
