  • Patent number: 5597037
    Abstract: An object of the present invention is to minimize a volume of a hollow body by a combination of a horizontal H-letter shaped type gas-liquid separator and a plurality of plate-fin heat exchangers having a larger heat exchange performance per volume. In the present heat exchanging apparatus, fluid and refrigerants flow about in the hollow body through pipes while gas and liquid phases of the refrigerants are repeatedly separated and mixed for heat exchange between the fluid and the refrigerants. The apparatus comprises a plurality of plate-fin heat exchangers for exchanging heat between the refrigerants and the fluid, and a gas-liquid separator including upper and lower accommodation portions which are hollow cylinders laid in a horizontal direction both ends of which are airtightly sealed and an intermediate accommodation portion which connects the upper accommodation portion to the lower accommodation portion so as to form a sideways H-letter shape.
