Title:
GAS-LIQUID SEPARATOR
Document Type and Number:
Japanese Patent JP2019124380
Kind Code:
A
Abstract:
To suppress reduction of a heat medium stored in a heat medium evaporator.SOLUTION: A gas-liquid separator 20-1 comprises a spiral tube 30 and an outer spiral tube 32. The spiral tube 30 is in spiral shape along the shape of the outer spiral tube 32 in a tube of the outer spiral tube 32. An opening at a lower end side of the spiral tube 30 of the gas-liquid separator 20-1 provides a heat medium inflow port, and an opening at an upper end side of the spiral tube 30 provides a heat medium outflow port. A heating fluid flows in from an upper end of a heating fluid passage 34 formed between the outer spiral tube 32 and the spiral tube 30, and descends in the heat fluid passage 34 and flows out from a lower end. The liquid-phase heat medium is attached to a tube wall of the spiral tube 30 by centrifugal force generated when the heat medium ascends in the tube of the spiral tube 30. A part of the liquid-phase heat medium attached to the tube wall is evaporated and ascends, and flows out from the outflow port. The remaining part of the liquid-phase heat medium attached to the tube wall moves along the tube wall by gravity force and returns to the inflow port.SELECTED DRAWING: Figure 3
