Document Type and Number:
Japanese Patent JP3068209
Kind Code:
B2
Abstract:
According to the present invention, there is provided a water vaporization type cooling apparatus for a small-capacity heating element which permit cooling the heating element to below the outer peripheral temperature and is suitable for environmental protection. The water vaporization type cooling apparatus of a heating element comprises a closed space sealing air therein and housing the heating element therein; a water sump portion provided in the close space for storing water; a waterproof layer formed on the surface of the heating element; a water-bearing layer formed on the surface of the waterproof layer, an end of the water-bearing layer, when the heating element is housed in the closed space, being immersed in water stored in the water sump portion; an air circuit connected the both ends thereof to the closed space, the air circuit forming a closed loop in which air is circulated in cooperation with the closed space; air circulating means, provided in the air circuit, for causing air to flow along the surface of the water-bearing layer by circulating air in the closed loop; dehumidifying means, arranged in the air circuit, for recovering through condensation and separation of water contained in air flowing along the surface of the water-bearing layer; and water returning means for returning water recovered by the dehumidifying means the water sump portion, wherein water impregnated in the water-bearing layer is vaporized by causing air to flow along the surface of the water-bearing layer so that the heating element is cooled by the latent heat of vaporization of water.
