<p>PURPOSE:To uniformly branch refrigerant by forming edge parts of a ceiling plate integrally molded by drawing a plurality of flowout tubes and a bottom plate integrally molded by drawing a single flowin tube in a welded refrigerant flow divider. CONSTITUTION:A refrigerant flow divider is composed of a ceiling plate 2 integrally molded by drawing a plurality of flowout tubes 3 and a bottom plate 4 integrally molded by drawing a single flowin tube 5, the edge parts of the plates are welded to reduce the inner volume of a body. Thus, a decrease in the speed of refrigerant in the body is eliminated, gas and liquid mixing state of the refrigerant in the tube 5 is maintained, and separation of the gas and the liquid is suppressed. Accordingly, even if the device is used in an inclined state, liquid storage is eliminated, and uniform branching is realized. Since the tubes 3 are integrally molded with the plate 2 to obtain its length, they scarcely protrude into the body, the height of the refrigerant inlet of the flowout tube is constant at the respective flowout tubes to provide uniform branching. An irregularity in the inflowing shape of the tube 5 is substantially eliminated to obtain stable flow division characteristic.</p> |
