ABSTRACT:
A cooling apparatus has a cooling vessel, containing a liquid as a thermal medium which absorbs latent heat by evaporation, and an absorber which absorbs the vapor of the liquid. The cooling vessel further contains one or more units of encapsulated gel refrigerant submerged in the liquid, which impede temperature increase of the liquid when an operation of the cooling apparatus is temporarily suspended. An alternative cooling vessel has one or more upwardly extending members partially submerged in the liquid and covered with liquid soaking material, so that the liquid soaks up in the material by capillary action and accelerates its evaporation. Another alternative cooling vessel has plural liquid tanks, one arranged on another, so that the total area for the evaporation of the liquid is multiplied. An additional alternative cooling vessel has a plurality of rotatable fins, partially submerged in the liquid, for accelerating the evaporation of the liquid.
