Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/130394
Kind Code:
A1
Abstract:
A heat exchanger (10) includes an auxiliary heat exchanging unit (40) comprising: a first auxiliary heat exchanging region (411) and a second auxiliary heat exchanging region (412). A main heat exchanging unit (30) includes a first main heat exchanging region (311), a second main heat exchanging region (312), a third main heat exchanging region (313), and a fourth main heat exchanging region (314). The first auxiliary heat exchanging region (411), the first main heat exchanging region (311), and the third main heat exchanging region (313) are each disposed upwind, in the flow direction, from the second auxiliary heat exchanging region (412), the second main heat exchanging region (312), and the fourth main heat exchanging region (314). The auxiliary heat exchanging unit (40) and the main heat exchanging unit (30) are configured so that when the heat exchanger (10) functions as an evaporator, a refrigerant flows in order through the first auxiliary heat exchanging region (411), the second auxiliary heat exchanging region (412), the first main heat exchanging region (311), the second main heat exchanging region (312), the fourth main heat exchanging region (314), and the third main heat exchanging region (313).
