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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . 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,
 wherein 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.   
     
     
         2 . 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,
 wherein 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 by fiber laser beam radiation.   
     
     
         3 . A refrigerator equipped with the heat exchanger for the refrigeration cycle of  claim 1 .
