Title:
EQUIPMENT COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/087629
Kind Code:
A1
Abstract:
A cooler (11) cools target equipment (2) by using latent heat from vaporization of a hydraulic fluid. A cold heat source-type heat exchanger (12) uses the cold heat of a low-temperature, low-pressure refrigerant circulating through a freezing cycle (30), radiates heat from hydraulic fluid that has vaporized in a cooler (11), and condenses the hydraulic fluid. An air cooled heat exchanger (13) uses cold heat of external air, radiates heat from hydraulic fluid that has vaporized in the cooler (11), and condenses the hydraulic fluid. The cooler (11), the cold heat source-type heat exchanger (12), and the air cooled heat exchanger (13) are connected by a gas pipe (14) and a liquid pipe (15). An external air temperature detection unit (16) detects external air temperature. A saturation temperature detection unit (17) detects the saturation temperature of hydraulic fluid circulating through a thermosiphon circuit (10). Heat radiation amount adjustment units (18, 20, 31, 33, 38, 41, 321, 322) adjust the amount of heat radiation from the hydraulic fluid flowing through the cold heat source-type heat exchanger (12), such that the saturation temperature of the hydraulic fluid is higher than the external air temperature.
