Condenser for use in vehicle

Abstract

A condenser for use in a vehicle (A 1 ) comprises, in an integrated manner, a condensation part ( 4 ), which cools a coolant that is discharged, at a high temperature and a high pressure, to the condensation part ( 4 ) from a compressor ( 1 ) of a refrigeration cycle, by radiating heat from the coolant by way of a heat exchange between the coolant and the external atmosphere, a reservoir tank ( 5 ) that stores the coolant that has been liquefied by the condensation part ( 4 ), and a supercooling part ( 6 ), which cools the liquid coolant that is discharged to the supercooling part ( 6 ) from the reservoir tank ( 5 ) at high pressure. The supercooling part ( 6 ) is configured to cool the liquid coolant that is discharged to the supercooling part ( 6 ) from the reservoir tank ( 5 ) at a high pressure by way of a heat exchange, which does not employ a radiator fin, between the high pressure liquid coolant and a low pressure coolant that is discharged from an evaporator ( 3 ) of the refrigeration cycle.
