METHOD OF MANUFACTURING Y-SHAPE REFRIGERANT DISTRIBUTOR FOR AIR CONDITIONING AND Y-SHAPE REFRIGERANT DISTRIBUTOR MANUFACTURED THEREBY

摘要

Disclosed is a method of manufacturing a refrigerant distributor for air conditioning and a refrigerant distributor manufactured thereby. The manufacturing method includes mixing copper powder with 30-60 vol% of a binder based on the volume of the copper powder, thus preparing a mixture for injection molding, subjecting the mixture to injection molding using a mold, thus producing an injection molded body having the shape of a distributor, removing the binder from the injection molded body, and sintering the binder- free molded body in a sintering furnace at 800-115O0C in a reducible or inert atmosphere, the method being thereby favorable for mass production owing to omission of additional mechanical processing and enabling the manufacture of a distributor having a smaller size, as for adaptation for the miniaturization of an apparatus, reducing loss of material, and leading to low manufacturing costs.
