PURPOSE:To enable a coolant level to be visually observed from a reservoir tank in an evaporative cooling apparatus, by providing an open/close means by which the upper part of a condenser is opened to the atmosphere, so that the coolant liquid level inside the condenser and that inside a reservoir tank can be made to be the same level. CONSTITUTION:The upper space of a reservoir tank 25 having a volume nearly equal to the inner volume of a condenser 3 is opened to the atmosphere via an atmosphere communicating passage 26, and a detachable cap 27 for filling coolant is provided on it. Further, the reservoir tank is connected to the lower tank 21 of the condenser 3 via the first coolant circulating passage 28, and is connected to a water jacket 2 via the second coolant circulating passage 29 in which a coolant feed pump 4 is interposed. On the connecting pipe 8 communicating the vapor outlet 7 of the water jacket 2 with the upper inlet 3a of the condenser 3, a cap 10 by which the upper part of the condenser 3 is opened to the atmosphere when the level of coolant is to be checked is detachably provided. |
