<P>PROBLEM TO BE SOLVED: To provide a configuration of a heat exchanger, coping with an air jet sent from a blowing fan. <P>SOLUTION: This heat exchange unit includes a heat exchanger (30) and the blowing fan (10) disposed on the air upstream side of the heat exchanger (30), wherein the blowing fan (10) includes a hollow plate-like fan body (11) having a membrane-like vibrator (20) on a front part (12), the air is taken from an intake hole (16) by vibration of the membrane-like vibrator (20) into an air chamber (17) in the fan body (11), and the air is discharged toward the heat exchanger (30) from an exhaust hole (18), and the air discharged from the blowing fan (10) exchanges heat with a refrigerant when passing the heat exchanger (30). The heat exchanger (30) includes a number of heat transfer pipes (32) disposed in parallel and foam metal (33) disposed in the periphery of each heat transfer pipe (32) and provided with a plurality of holes, wherein the foam metal (33) forms a number of bypass air passages. <P>COPYRIGHT: (C)2009,JPO&INPIT |
