Abstract

Provided is a double pipe heat exchanger that can be compactly configured but is capable of restraining the outflow of a liquid refrigerant contained in a gas liquid two phase refrigerant from an inner pipe and is capable of preventing the occurrence of refrigerant flood back. The double pipe heat exchanger (31) is provided with: an outer pipe (32) that allows a high pressure liquid refrigerant to flow therethrough; and an inner pipe (33) having an inlet side end (33A) which allows a low pressure gas liquid two phase refrigerant which is obtained by reducing the pressure of the high pressure liquid refrigerant to flow in and an outlet side end (33B) connected to the suction side of a compressor. The double pipe heat exchanger (31) comprises a plurality of vertical pipes (34A 34B) arranged in a vertical direction and a curved pipe (35) that connects the ends of the plurality of vertical pipes (34A 34B). The outlet side end (33B) of the inner pipe (33) is provided to the upper end of one vertical pipe (34B) and the inlet side end (33A) of the inner pipe (33) is provided to the upper end of the other vertical pipe (34A).
