Title:
STACKED HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2016/067551
Kind Code:
A1
Abstract:
A stacked heat exchanger is provided with a heat exchange section (1) and a gas-liquid separation section (2). The heat exchange section exchanges heat between the refrigerant of a refrigeration cycle and a heat medium. The gas-liquid separation section separates the gas and liquid components of a refrigerant having flowed into the gas-liquid separation section. The heat exchange section is formed by stacking and joining a plurality of first plate-like members (11). A plurality of refrigerant passages (12) through which the refrigerant flows and a plurality of heat medium flow passages (13) through which a heat medium flows are formed between the plurality of first plate-like members. The plurality of refrigerant passages and the plurality of heat medium flow passages are arranged next to each other in the stacking direction of the plurality of first plate-like members. In the refrigerant passages, there are arranged: condensing sections (121) for exchanging heat between a gas phase refrigerant and the heat medium to condense the gas phase refrigerant; and supercooling sections (122) for supercooling a liquid phase refrigerant by exchanging heat between a heat medium and a liquid phase refrigerant obtained by gas-liquid separation in the gas-liquid separation section, the condensing sections (121) and the supercooling sections (122) being arranged next to each other in the direction perpendicular to the stacking direction. In the refrigerant passages, the condensing sections and the supercooling sections are separated by heat insulation sections (123).
