Title:
HEAT EXCHANGER AND VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026485
Kind Code:
A1
Abstract:
This heat exchanger (16) is applied to a heat pump cycle (10) which can be switched between a cooling mode in which a fluid to be temperature-controlled is cooled by switching the circulation path of a refrigerant including an oil, and a heating mode in which the fluid to be temperature-controlled is heated. An outdoor heat exchanger is provided with: a core part (17) which condenses the refrigerant during the cooling mode and evaporates the refrigerant during the heating mode; and a liquid receiver (18) having a liquid storing part (184) which temporarily stores a portion of the refrigerant flowing out from the core part in the cooling mode as an excess refrigerant in the cycle. In addition, the outdoor heat exchanger is provided with a valve device (30) which switches the circulation path of the refrigerant in the cycle. The valve device is provided with an intake-side flow passage (306) which guides the refrigerant in the liquid storing part toward the refrigerant intake side of a compressor (12) of the heat pump cycle during the heating mode. In addition, the intake-side flow passage communicates with a lower section (184c) of the liquid storing part, the lower section (184c) being closer to a lower end section (184b) than to an upper end section (184a) of the liquid storing part.
