Abstract:
A water vaporization type cooling apparatus of a heating element comprising:a closed space sealing air therein and housing said heating element therein;a water sump portion provided in said close space for storing water;a waterproof layer formed on the surface of said heating element;a water-bearing layer formed on the surface of said waterproof layer, an end of said water-bearing layer, when said heating element is housed in said closed space, being immersed in water stored in said water sump portion;an air circuit connected the both ends thereof to said closed space, said air circuit forming a closed loop in which air is circulated in cooperation with said closed space;air circulating means, provided in said air circuit, for causing air to flow along the surface of said water-bearing layer by circulating air in said closed loop;dehumidifying means, arranged in said air circuit, for recovering through condensation and separation of water contained in air flowing along the surface of said water-bearing layer; andwater returning means for returning water recovered by said dehumidifying means said water sump portion,wherein water impregnated in said water-bearing layer is vaporized by causing air to flow along the surface of said water-bearing layer so that said heating element is cooled by the latent heat of vaporization of water.
