Title:
HEAT EXCHANGER, AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/246337
Kind Code:
A1
Abstract:
A heat exchanger (14) causes a refrigerant containing oil to perform heat exchange with a heating medium so as to absorb heat from the heating medium. The heat exchanger is provided with a flow channel layered body (140) formed by alternately layering a plurality of refrigerant flow channel parts (141) through which the refrigerant flows, and a plurality of heating medium flow channel parts (142) through which the heating medium flows. In the external dimensions of the plurality of refrigerant flow channel parts, the dimension in a first direction orthogonal to the layering direction of the flow channel layered body is greater than the dimension in a second direction orthogonal to the layering direction and the first direction. In the flow channel layered body, the plurality of refrigerant flow channel parts is provided with a refrigerant inlet part (143) serving as a refrigerant inlet, and a refrigerant outlet part (144) serving as a refrigerant outlet. The flow channel layered body is installed such that the first direction is close to the vertical direction. The refrigerant outlet part is provided at a position closer to a lower end site (141b) of a refrigerant flow channel part than an upper end site (141a) of the refrigerant flow channel part.
