In the present invention, in actuality, the spray cooling efficiency due to the contact effect between the fins of the condenser and the spray water must be taken into consideration. However, as compared with the above-mentioned water cooling, ultrafine grained water utilizing latent heat of vaporization is used. In the case of spraying, most of it uses the heat of vaporization, so theoretically the latent heat of vaporization is 580 Kca / kg at a water temperature of 25 degrees, so it is directly cooled with the same weight of water. It is possible to obtain a large cooling effect as compared with the case. As a result, if the ultrafine-grained spray water efficiently reaches the heat dissipation surface of the condenser, condenser cooling similar to the water-cooled condenser method can be expected.
