A water vaporization type cooling apparatus for cooling a heat-generating unit comprises a container which is made of a good thermal conductive material and has an opening, a selective water vapor permeable membrane which is mounted to the container so as to cover the opening and forms a closed space cooperatively with the container, and water charged in the closed space. In the water vaporization type cooling apparatus, the container is thermally connected to the heat-generating unit and dehydrated air flows along the outer surface of the selective water vapor permeable membrane, whereby the heat-generating unit is cooled down.

A method for recovering a condensable gas from a mixed gas uses a condensable gas recovering apparatus. The apparatus comprises a compressor for compressing a mixed gas comprising a condensable gas and an incondensable gas, a mixed gas separator including a cooler and an adsorbent that adsorbs the incondensable gas, and a vacuum exhauster. The method comprises the steps of introducing the mixed gas highly compressed by the compressor into the mixed gas separator, liquefying and recovering the condensable gas by cooling the mixed gas separator with the cooler while the adsorbent adsorbs the incondensable gas contained in the mixed gas in a high pressure state, and exhausting the incondensable gas from the adsorbent in a low pressure state where the gas in the mixed gas separator has been exhausted by the vacuum exhauster. Therefore, recovery of the condensable gas is carried out with high reliability, and mixing of a large quantity of the condensable gas into the incondensable gas is easily prevented.

Water evaporation type cooling apparatus by means of electrolytic

This invention has as its object to obtain a compact solid high polymer electrolytic module having a large electrolytic reaction capacity. An electrolytic membrane (20) is constituted in such a manner that strip-shaped anodes (23) and strip-shaped cathodes (22) are formed at a predetermined interval opposite to each other on both the surfaces of a belt-shaped solid high polymer electrolytic membrane (21). A frame (30) is constituted in such a manner that feeding terminals (33a, 33b) are formed on a pair of side edges (31a, 31b) of a frame member (31) having an opening (32) on one side. A plurality of frames (30) are stacked such that the openings (32) alternately face upward and downward. The electrolytic membrane (20) is folded at counter edges (31c) of the frames (30) and held between the adjacent frames (30) , thereby constituting a stereoscopically corrugated structure in a stacking direction of the frames (30).

A water evaporation type cooling system equipped with a hermetically sealed housing and a solid electrolytic membrane placed to divide the hermetically sealed housing into first and second hermetically sealed spaces. Water is reservoired within the first hermetically sealed space, while a condenser is situated to communicate with the second hermetically sealed space. A direct-current voltage is applied to the solid electrolytic membrane, with the result that a water electrolytic reaction takes place on its first hermetically sealed space side surface, while a water production reaction occurs on its second hermetically sealed space side surface. Protons produced by the water electrolysis pass through the solid electrolytic membrane to contribute to a water production reaction. Steam within the first hermetically sealed space is transferred to the second hermetically sealed space whereas the oxygen within the second hermetically sealed space is shifted to the first hermetically sealed space. Thus, the humidity within the first hermetically sealed space falls to accelerate the evaporation of the water reservoired within the first hermetically sealed space, thereby inducing a temperature drop.
