REFRIGERANT DISTRIBUTOR AND PLATE-TYPE HEAT EXCHANGER FOR EVAPORATOR OF REFRIGERATION AND AIR-CONDITIONING SYSTEM HAVING SAME

摘要

The present invention relates to a refrigerant distributor which allows a refrigerant introduced through a refrigerant inlet port of a plate-type heat exchanger used in an evaporator or the like in a refrigeration and air-conditioning system to be uniformly distributed to refrigerant flow channels formed in the heat exchanger and is able to prevent loss of the liquid refrigerant caused by a flashing phenomenon in which part of the liquid refrigerant is instantly vaporized in an expansion valve by adiabatic expansion, and to a plate-type heat exchanger for an evaporator of a refrigeration and air-conditioning system, having the refrigerant distributor. The plate-type heat exchanger for the evaporator of the refrigeration and air-conditioning system, according to the present invention, comprises the refrigerant inlet port and a refrigerant outlet port through which the refrigerant is introduced and discharged, and a plurality of channels communicating with the refrigerant inlet port and the refrigerant outlet port formed therein, wherein the refrigerant distributor is formed in the refrigerant inlet port. The refrigerant distributor is formed in a plate shape, and has a plurality of refrigerant distribution holes, which can reduce flashing of the refrigerant caused by the adiabatic expansion of the refrigerant while evenly distributing the refrigerant introduced through the refrigerant inlet port to each of the channels.;COPYRIGHT KIPO 2017
