Abstract

PURPOSE: To prevent the mixing of both heat receiving and radiating liquids by enclosing operation liquid under pressure in a closed vessel having upper and lower surfaces, and arranging a conduit for heat receiving fluid on the upper surface of the closed chamber and a conduit for heat radiating fluid on the lower surface and permitting heat transfer only in one direction.

CONSTITUTION: On the bottom surface of a closed vessel 1, a wick 2 made of such as glass fiber is arranged. On the upper surface of the closed vessel 1, a primary conduit 4 for heat receiving fluid is arranged integrally through roll bonding method, and on the lower surface, a secondary conduit 7 for heat radiating fluid is arragned. The closed vessel 1 is heat-insulated by heat-insulating material and supported by outer frames 10 and 11. With these constitution, when heat receiving and radiating fluids are supplied to the primary and the secondary conduits 4 and 5 respectively, operation liquid is evaporated by the heat of radiation fluid, and delivers latent heat to the heat receiving fluid in the upper part, and condenses and drops due to the dead load and circulates. Thus, heat transfer arises only from the lower part to the upper part, and as heat receiving and radiating fluids flow in respective conduits, mixing is prevented.
