。Next, the operation will be explained. Oil (υ) is heated and heated to a high temperature in the spindle system of the machine tool (υ is introduced from the side of the guide means q1 arranged in the oil tank (2) to one side of it via the introduction pipe Q force. , the high-temperature oil (1) is guided horizontally to the heat absorption part (18a) of the heat pipe (to) and circulates.At this time, the heat absorption part (18a) of the heat pipe @
1aa) is heated, and this heating) also heats the working liquid sealed inside it, absorbs the oil tlJO heat as latent heat of vaporization, vaporizes it, and transfers it to the heat radiation part (18b) side of the heat vibro inside. Moving. Heat pipe (2
) The vapor of the working liquid such as fluorocarbon that has moved to the heat radiating part (18b) side is cooled by the surrounding air by the heat radiating fan (4). At this time, the vapor of the working liquid such as fluorocarbons condenses and liquefies, but the latent heat of condensation is released to the surrounding air and the oil (1)
The heat is released into the surrounding air. The condensed and liquefied working liquid moves inside the heat pipe μs to the endothermic part (18a) and returns thereto. In this way, the heat of the high temperature oil (1) passing through the heat absorption part (18a) of the heat vibro is transferred from the heat absorption part (18a) of the heat vibro by repeating the vaporization and liquefaction of the working liquid in the heat pipe C13. It is transported to the heat radiating part (18b) of the heat pipe (6) and radiates heat to the surrounding air. Therefore, the high-temperature oil tlJ that has flowed into the guide means (6) is deprived of heat at the endothermic part (18a) of the heat pipe (to), and its temperature is lowered and cooled, becoming a low-temperature oil (goods), and the guide means αQ The oil is led out into the oil tank (2) from the top of the oil reservoir plate H on the other side (16b). This low-temperature oil (g) is guided to the main shaft system of the machine tool by a pump (20C) through a suction filter (20a).

の油量を工作機械の主軸系に確実に供給できる。As mentioned above, the temperature on the heat absorption part (18a) side of the heat pipe 03, that is, the temperature of the oil (1) introduced into the guide means (6) and the temperature on the heat radiation part (18b) side of the heat pipe (to) In other words, the cooling due to the temperature difference with the temperature of the surrounding air (latent heat exchange inside the heat vibro) is controlled and carried out continuously, and the oil is drawn out into the oil tank (2). The heat pipe acts to bring the temperature of the oil closer to the temperature of the surrounding air, and when the temperature becomes similar to the temperature of the surrounding air, no latent heat exchange occurs inside the heat pipe and, accordingly, no cooling action occurs. That is, the amount of heat exchanged by the heat pipe μs is proportional to the size of the temperature difference between the oil in the guide means 01 and the surrounding air, and if the amount of heat generated on the machine tool side is small, the oil temperature in the guide means 00 also increases. It gets lower. Therefore, since the temperature difference between the oil temperature inside the guide means M and the ambient air side is small, the amount of heat exchanged by the heat pipe side is also small, and there is no misalignment due to overcooling, and the cooling amount is naturally controlled to match the heat generation amount. Continuous cooling is possible. As a result, conventional refrigeration equipment (7
) There is no pulsation in the oil temperature due to ON/OFF control, and therefore there is no pulsation in machining/machining accuracy, resulting in highly reliable machining accuracy. In addition, the oil tank (
Even if the oil level in the pipe is greatly reduced, the high-temperature oil 11J is maintained in the guide means Ql19 (oil sump plate CLI), and passes through the guide means αΩ to the heat absorbing part of the heat pipe 4. After being cooled in (43a), the oil (7) in a low temperature state is transferred from the top of the oil sump plate Ql to the oil tank (2).
derived within. Therefore, the amount of oil at a low temperature can be reliably supplied to the spindle system of the machine tool regardless of oil level fluctuations.

得ることができる。As explained above, this invention is a heat pipe that has a heat absorbing part disposed inside the oil tank and a heat radiating part disposed outside the oil tank, and transports the heat absorbed by the heat absorbing part to the heat radiating part and radiates the heat. A heat dissipation device disposed in the heat dissipation section of the heat pipe, and a heat dissipation device disposed in the heat absorption section of the heat pipe introduce high-temperature oil, and guide the high-temperature oil from one side to the heat absorption section Eζ of the heat pipe. A guide means for guiding the oil, which has become low temperature due to heat absorption in the endothermic part, from the other side into the oil tank, and an oil reservoir disposed on the other side of the guide means to ensure the amount of oil in the guide means. By providing a plate, the temperature is naturally controlled and continuously cooled by the temperature difference between the temperature on the heat absorption part side of the heat pipe and the temperature on the heat radiation part side of the heat pipe.
It is possible to obtain a heat exchange device that can supply stable oil without pulsation to equipment.
