れ温度が下がり冷却され、低温状態の油（８）となる。Next, the operation will be explained. Oil (1) heated and humidified to a high temperature in the spindle system of a machine tool is discharged into an oil tank (2). The high temperature oil that has flowed into the oil tank (2) passes through the heat absorption part (3a) of the heat pipe (3).
At this time, the heat absorption part (3a) of the heat pipe (3) is heated, and the working liquid (4) sealed inside the heat pipe (3) is heated.
The oil is also heated, absorbs heat from the oil as latent heat of vaporization, becomes vapor, and moves to the heat radiation part (3b) side of the heat pipe (3) inside. The heat dissipation part (3b) of the heat pipe (3)
) The vapor of the working liquid (4), such as fluorocarbon, is cooled by the surrounding air by the heat dissipation fan (5). At this time, the vapor of the working liquid (4) such as fluorocarbon is condensed and liquefied, but the latent heat of condensation is released to the surrounding air, and the heat of the oil is radiated to the surrounding air. The condensed and liquefied working liquid (4) moves internally to the endothermic part (3a) of the heat pipe (3) and returns thereto. In this way, by repeatedly vaporizing and liquefying the working liquid (4) in the heat pipe (3), the heat of the high-temperature oil (1) passing through the heat absorption part (3a) of the heat pipe (3) is heated. The heat is transferred from the heat absorption part (3a) of the pipe (3) to the heat radiation part (3b) of the heat pipe (3), and is radiated to the surrounding air. Therefore, the high temperature oil (21) that has flowed into the oil tank (21)
The heat of 1) is taken away by the heat absorbing part (3a) of the heat pipe (3), the temperature is lowered and the oil is cooled down, becoming a low-temperature oil (8).

配管（７ｂ）を通して工作機械の主軸系に導かれる。This low-temperature oil (8) is taken in by a pump (7c) through a comb filter (7a),
It is led to the spindle system of the machine tool through the pipe (7b).
