Title:
HEAT EXCHANGER AND FREEZING CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104050
Kind Code:
A1
Abstract:
The present invention is provided with: a plurality of first heat-transfer pipes (11) arranged at intervals therebetween in a first direction and each including a first end and a second end; a plurality of second heat-transfer pipes (12) which are arranged to be opposed, at intervals from the plurality of first heat-transfer pipes (11) in a second direction intersecting the first direction, to the plurality of first heat-transfer pipes (11), which are arranged on the leeward side relative to the plurality of first heat-transfer pipes (11), and which each include a third end and a fourth end; a plurality of fins (13) connecting the adjacent first heat-transfer pipes (11) and also connecting the adjacent second heat-transfer pipes (12); a first distribution unit (20) connecting the first ends of the plurality of first heat-transfer pipes (11) to the third ends of the plurality of second heat-transfer pipes (12); and second distribution units (24, 25, 26) connecting the second ends of the plurality of first heat-transfer pipes (11) to the fourth ends of the plurality of second heat-transfer pipes (12). The first distribution unit (20) includes a flow rate control unit (2) which can perform switching between a first state and a second state. In the first state, a coolant flows through the plurality of first heat-transfer pipes (11) and the plurality of second heat-transfer pipes (12). In the second state, the flow rate of the coolant only in the plurality of first heat-transfer pipes (11) is lower than that in the first state.
