Abstract
A heat exchanger includes a heat exchanger body and fasteners used to mount the body on an automobile or the like. The heat exchanger body comprises flat tubes and fin members alternatingly stacked on each other and a pair of hollow headers, with the ends of each tube being connected in fluid communication with the headers. Each fastener comprises a contacting concave portion with a shape which allows it to fit on an outer peripheral surface of a header, a hooking portion protruding from an end of the concave portion, and a fastening portion extending outwardly from another end of the concave portion. The concave portion is placed in close contact with the peripheral surface of the header, with a hook end of the hooking portion being inserted in between two adjacent tubes. The fasteners are soldered to the heat exchanger body and become integral with it.
