Claim Text:
1. An accumulator heat exchanger, comprising: an accumulator housing; a heat exchanger made of metal and including: a high pressure refrigerant tube inserted into and coupled to two of the tube insertion ports of the heat exchanger in a U shape, the high pressure refrigerant tube allowing a high pressure refrigerant supplied from a condenser of a cooling cycle to flow therein; a low pressure refrigerant tube inserted into the lower space under the heat exchange bodies through a bottom of the accumulator housing and passing through the heat exchange bodies from the lower space to the upper space via one of the tube insertion ports of the heat exchanger, the low pressure refrigerant tube having an upper end formed to be open at the upper space of the accumulator housing, the upper end of the low pressure refrigerant tube extending upwardly from the heat exchange bodies and then bent downward to face the heat exchange bodies to eject the low pressure refrigerant supplied from an evaporator of the cooling cycle into the upper space such that the ejected low pressure refrigerant flows from the upper space down to the lower space through the hollow polygonal cross sections of the heat exchange bodies; and a refrigerant gas exhaust tube having an upper end formed to be open at the upper space of the accumulator housing, the refrigerant gas exhaust tube being inserted into one of the tube insertion ports of the heat exchanger to pass through the heat exchange bodies and guide refrigerant gas in the accumulator housing to a compressor of the cooling cycle.
