Abstract (en)

Disclosed herein is a heat exchanger for a refrigeration cycle which is configured in such a manner that refrigerant discharged from a compressor circulates a condenser, a capillary tube, an evaporator, a suction pipe and the compressor in sequential order, and in which the outer surface of the capillary tube and the outer surface of the suction pipe are in thermal contact with each other. In the heat exchanger, the suction pipe and the capillary tube are made of aluminum which is inexpensive, instead of the copper-made suction pipe and the copper-made capillary tube of existing heat exchangers for the refrigeration cycle, and which is easy to apply the meandering. The capillary tube is made of aluminum alloy selected from JIS 3000 series alloy and the suction pipe is made of aluminum selected from JIS 1000 series aluminum. The outer surface of the capillary tube and the outer surface of the suction pipe are melted and bonded together, or particularly, are melted and bonded together by fiber laser beam radiation. Moreover, the invention is directed to a refrigerator being equipped with a heat exchanger of the kind as mentioned above.
