Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/070808
Kind Code:
A1
Abstract:
[Problem] To provide a cooling device capable of appropriately adjusting the flow rate of a refrigerant while keeping the product cost low. [Solution] A cooling device (10) comprises: an expansion device (14) that expands a refrigerant; a refrigerant distribution device (16); a plurality of upstream refrigerant flow paths (20a, 20b); a plurality of heat exchange units (30a, 30b); a plurality of downstream refrigerant flow paths (22a, 22b); and a refrigerant merging device (24) that merges the refrigerants that have flowed through the plurality of downstream refrigerant flow paths. The flow rate of the refrigerant in one heat exchange unit (30a) is less than that of the refrigerant in the other heat exchange unit (30b), and the downstream refrigerant flow path (22a) connected to the one heat exchange unit (30a) is provided with a downstream detection device (40) that detects the temperature of the refrigerant in the downstream refrigerant flow path (22a).
