ABSTRACT:
A evaporator for use in a refrigerating cycle in an air conditioning apparatus for a vehicle. The evaporator is provided with a heat exchanger and an evaporator. The heat exchanger has an inlet passageway for leading the refrigerant from the condenser to the evaporator, and an outlet passageway for leading the refrigerant from the evaporator to the compressor. A heat exchange between the inlet refrigerant and the outlet refrigerant at the heat exchanger part takes place, so that a combined gas-liquid state refrigerant is introduced into the outlet passageway of the heat exchanger from the evaporator, whereby a superheating state of the refrigerant is generated in the outlet passageway, and a result, no superheating action occurs in the evaporator, and thus the refrigerant in the evaporator is kept at a constant temperature, whereby the cooling efficiency of the evaporator is increased.
