Title:
COOLING DEVICE AND GAS-LIQUID SEPARATION TANK
Document Type and Number:
WIPO Patent Application WO/2018/164084
Kind Code:
A1
Abstract:
(Problem) To provide a cooling device that uses the phase change of a refrigerant and which, when introducing a gas-liquid separation tank, achieves both suppression of pressure loss in the gas-liquid separation tank and a simple piping structure.
(Solution) This sealed container, capable of internally holding a refrigerant, is provided with: a condensed refrigerant inlet which, at the lower end, passes through an upper bottom surface or a side surface of the container and allows inflow of condensed-state refrigerant from above; a condensed refrigerant outlet which, at the upper end, opens in the lower bottom surface of the container and allows outflow of condensed-state refrigerant downwards; a gas-liquid mixed refrigerant inlet which at the upper end passes through the lower bottom surface, allows inflow of the mixed liquid-gas state refrigerant from below, and which allows outflow of the gas-state portion of the inflowing refrigerant upwards and outflow of the liquid-state portion of the inflowing refrigerant towards the wall of the container; and a gas refrigerant outlet which is arranged in a direction parallel to the gas-liquid mixed refrigerant inlet, opens at the lower end in the upper bottom surface, and allows outflow of the gas-state refrigerant upwards.
