Abstract
A heat exchanger includes headers and tubes two ends of each of which are connected with and communicate the headers. Each of fins is disposed between adjacent tubes. An end cover is formed with a center hole and fixed to a proximal end of one of the headers. A distal end of a sleeve passes through the center hole to extend into the header, and a proximal end of the sleeve is held by a proximal end surface of the end cover. A first distribution-collection tube is fixed to the sleeve and defines an open proximal end and a closed distal end passing through the sleeve to extend into the header in which openings are formed along a longitudinal direction of the distribution-collection tube in a portion thereof extended into the header. A fixing nut is screwed onto the end cover to press the proximal end of the sleeve against the proximal end surface of the end cover.
