Micro-channel heat exchanger with adjustable distribution pipe

摘要

A micro-channel heat exchanger comprises a first header (1); a second header (2); a plurality of tubes (3); a plurality of fins (4) each disposed between two adjacent a plurality of tubes; a first end cover (8a) formed with a first center hole and fixed to a proximal end of the first header; a first sleeve (10a) mounted to the first end cover (8a); a first distribution-collection tube (5) formed with a plurality of first openings (7a), and fixed to the first sleeve (10a) and extend into the first header (1); and a first fixing nut (11a) screwed onto the first end cover (8a). According to the present invention, the length of the distribution-collection tube (5) extended into the header (1) is adjustable, and the distribution-collection tubes (5) may be detachably assembled to the header (1), so that it is easy to replace and maintain the distribution-collection tube (5), thus enhancing the applicability.
