PURPOSE:To economically and evenly cool bearing portions by connecting two heat receivers with a single condenser through each vapor line and further communicating the condenser with the two heat receivers through each liquid line. CONSTITUTION:When temperature rise of a bearing portion on a heat receiver 1 side becomes greater than that of a bearing portion on the other heat receiver 11 side, working liquid in the heat receiver 1 upon vaporizing generates vapor quantity, vapor pressure and vapor temperature which are greater than those of working liquid in the heat receiver 11 to be derived of greater latent heat of vaporization and thereby to cool the bearing portion on the heat receiver 1 side, namely to hold the temperature rise of the bearing portion on the heat receiver 1 side at a lower level than that of the bearing portion on the heat receiver 11 side. Then, hot vapor vaporized in the heat receiver 1 and cool vapor vaporized in the heat receiver 11 are introduced through vapor lines 1 and 31, respectively to a condenser 5 to be cooled. Liquid condensed in the condenser 5 is divided and returned through liquid lines 4 and 41 to the heat receivers 1 and 11, respectively. Accordingly, temperature of the liquid to be returned to the heat receiver 1 becomes higher and temperature as to the heat receiver 11 becomes lower, thereby increasing the temperature rise of the bearing portion on the heat receiver 11 side and as a result, holding the difference of temperature rise between both bearing portions at a minimum level. |
