PURPOSE:To lighten and miniaturize the structure of a reservoir tank to improve rove the cooling efficiency by bringing a heat absorbing part of a heat pipe into contact with the operating oil, and leading a heat radiating part outside. CONSTITUTION:The operating oil 3 is collected in a reservoir tank 3, and a heat absorbing part 4a of a heat pipe 4 is soaked in the operating oil 3, and a heat radiating part 4b is led out of the reservoir tank 1 for arrangement. The heat of the operating oil 3 thereby heats the heating medium inside of the heat pipe 4 at the heat absorbing part 4a of the heat pipe 4 to vaporize it. This heating medium rises inside of the heat pipe 4, and is cooled for condensation at the heat radiating part 4b, and is changed to the liquid to be lowered inside of the heat pipe 4. The operating oil 3 inside of the reservoir tank 1 is cooled by circulating the heating medium inside of the heat pipe 4. |
