Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/174593
Kind Code:
A1
Abstract:
A coolant flow path (2) of this cooling device (100) includes an inlet opening (22) for inflow of the refrigerant (5), distribution paths (23) branching from the inlet opening and connecting to each heat exchange unit (21), and an outlet opening (24) for outflow of at least partially gasified refrigerant. Between the branching (23a) of the distribution paths and the heat exchange units, a resistance body (30) is provided which, by increasing the flow path resistance, suppresses fluctuation in the distribution amount of the refrigerant accompanying fluctuation of the heat generation amount of a heat generating body (M).
