Title:
HEAT EXCHANGER AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/180240
Kind Code:
A1
Abstract:
In order to improve the heat exchanging efficiency of a heat exchanger provided with a windward side heat exchange part and leeward side heat exchange part, the windward side heat exchange part (51) is disposed on the windward side with respect to a blowing direction indicated by the arrow (Ar1). The leeward heat exchange part (61) is disposed on the leeward side of the windward side heat exchange part (51). When functioning as an evaporator, a gas outlet pipe (55) is a windward side refrigerant outlet provided in one end side of a windward side flat pipe of the windward side heat exchange part (51), and a gas outlet pipe (65) is a leeward side refrigerant outlet provided in one end side of a leeward side flat pipe of the leeward side heat exchange part (61). A first resistance against the refrigerant flowing toward the windward side heat exchange part (51) and a second resistance against the refrigerant flowing toward the leeward side heat exchange part (61) are adjusted so that the degree of superheating of the refrigerant at the leeward side refrigerant outlet is smaller than that at the windward side refrigerant outlet.
