Heat exchanger combined with decompression device for cooling circuit has pressure reduction unit for performing heat exchange between high and low pressure coolant or refrigerant

摘要

The arrangement has a pressure reduction unit (300) for the coolant or refrigerant in the coolant circuit, and a heat exchanger circuit (600) combined with the pressure reduction unit. This performing a heat exchange between the high pressure coolant or refrigerant after decompression. The heat exchange unit has a first pipe carrying the high pressure coolant and a second carrying the low pressure coolant. The pressure reduction unit has a housing forming a coolant or refrigerant channel, and the first and second pipes are laid around the housing and are in contact.
