PROBLEM TO BE SOLVED: To obtain the cooler of an enclosed structure which shows the high reliability without using a stirring fan by a method wherein a duct through which warm air staying in the upper part of the enclosed structure is guided and supplied to the heat receiving part of a heat pipe as internal air is provided near a frame in an enclosed structure. SOLUTION: High temperature warm air which is moved into the upper part in an enclosed structure 1 is taken in by an internal fan 15 as internal air A through a taking inlet 17a and supplied to the heat receiving part 12a of a heat pipe 12 through an exhaust outlet 17b. The internal air A whose heat is removed while it flows through the heat receiving part 12a and whose temperature is lowered is returned to the inside of the enclosed structure 1 to circulate. If the heat receiving part 12a is heated by the internal air A, operation liquid 13 is vaporized and moved to the heat radiation part 12b of the heat pipe 12. On the other hand, external air B is supplied to the heat radiation part 12b by an external fan 16 and discharged out. The vapor of the operation liquid 13 is condensed and liquefied and returned to the heat receiving part 12a. |
