Embodiment Construction

[0274] 1-5 show an evaporating device to be applied to a refrigeration system used on a vehicle as an embodiment of the present invention. As shown in these drawings, the evaporation equipment is to be applied to the use of CO 2 It is an apparatus of a vapor compression refrigeration cycle of refrigerant, and includes an evaporator 100 and a gas-liquid separator 70 provided at a part of a refrigerant passage of the evaporator 100 .

[0275] The evaporator 100 has a pair of flat upper and lower water storage tanks 10 and 30 as basic structural parts; Both ends are fluidly connected to the pair of water storage tanks 10 and 30, the flat heat exchange tubes are arranged parallel to each other in the longitudinal direction (left-right direction) of the water storage tanks, and in the width direction (front-rear direction) of the water storage tanks. ) arranged in two rows; and corrugated fins, each corrugated fin is arranged between adjacent tubes 1a and 1b.

[0276] As shown in...

Abstract

The present invention aims to provide an evaporator using CO2 refrigerant which can prevent the dryness of refrigerant vapor in the passage of the evaporator from increasing and obtain good heat exchange efficiency. The present invention relates to an evaporator for a refrigeration system, the evaporator has a refrigerant inlet (51b) for introducing refrigerant, a refrigerant outlet (51a) for discharging refrigerant, and a The refrigerant introduced in the inlet (51b) evaporates and guides the refrigerant to the evaporator passage of the refrigerant outlet (51a). An intermediate outlet (gas outlet 73 ) is provided at an intermediate portion of the evaporator channel. Among the refrigerants passing through the middle part from the refrigerant inlet (51b), the refrigerant with high vapor quality flows out from the middle outlet 73, so as to prevent the vapor quality of the refrigerant from increasing.
