Title:
HEAT EXCHANGE UNIT AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/030812
Kind Code:
A1
Abstract:
This heat exchange unit comprises: a heat exchanger having a plurality of heat transfer tubes; and a plurality of refrigerant distributors. Each of the plurality of refrigerant distributors comprises an inflow tube into which refrigerant flows, and a plurality of flow dividing tubes out of which refrigerant flows. The plurality of flow dividing tubes are connected respectively to the plurality of heat transfer tubes. The inner diameter of the inflow tubes of a refrigerant distributor having a comparatively lower average value for the height of the connection positions between the plurality of flow dividing tubes and the plurality of heat transfer tubes is smaller than the inner diameter of the inflow tubes of a refrigerant distributor having a comparatively higher average value for the height of the connection positions between the plurality of flow dividing tubes and the plurality of heat transfer tubes. In each of the plurality of refrigerant distributors, the inner diameter of a flow dividing tube from among the plurality of flow dividing tubes which has a comparatively lower connection position with a heat transfer tube is smaller than the inner diameter of a flow dividing tube from among the plurality of flow dividing tubes which has a comparatively higher connection position with a heat transfer tube.
