Abstract: Disclosed therein is a heat exchanger for a refrigeration cycle in which a suction pipe and a capillary tube are made of aluminum which is inexpensive, instead of the copper-made suction pipe and the copper-made capillary tube of the existing heat exchanger 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, and 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. The heat exchanger is equipped in a refrigerator.

Abstract: A heat exchanger for a refrigeration cycle that in terms of functionality and quality is within the allowable range of and comparable to a conventional heat exchanger for a refrigeration cycle, has substantially the same structure as a conventional heat exchanger for a refrigeration cycle, and enables reduced costs, as well as method for manufacturing the heat exchanger are provided. A heat exchanger for a refrigeration cycle is configured so that a refrigerant discharged from a compressor is circulated to a condenser, a capillary tube, an evaporator, a suction pipe, and the compressor, and so that the external surfaces of the capillary tube and the suction pipe are thermally in contact with each other. The material of the capillary tube and the suction pipe is aluminum. The locations at which the external surfaces of the capillary tube and the suction pipe are joined where fillets of a brazing material being an Al—Si alloy and a Zn—Al alloy are formed.
