用冷却装置を提供することを目的としたものである。This invention was made in order to eliminate the drawbacks of the above-mentioned conventional ones, and includes a lower wind tunnel that is arranged at the bottom of the cooler and rotates by wind force so that the opening always coincides with the wind direction, and a lower wind tunnel that is arranged around the cooler. By providing an upper wind tunnel formed in the shape of a chimney extending from the upper part to the upper part, and a fan attached to the upper wind tunnel, natural wind is taken in from around the lower part, and the oil flowing in the cooling pipe in the cooler part is cooled. After heat exchange,
This uses the chimney effect to promote air flow by discharging to the top.The opening that takes in the wind always faces the direction of the wind as the wind direction changes, and when there is a wind, it uses natural wind. Only when there is no wind, a fan installed in the upper wind tunnel forces air in from the bottom, adds a chimney effect, and discharges it to the top. The purpose of this invention is to provide an energy-saving and highly efficient cooling device for oil-filled electrical equipment that prevents apparent deterioration of cooling performance due to wrap-around.

できた。In the cooling system configured as described above, high-temperature insulating oil is forced to circulate within the cooling pipe of the cooler 1 in the direction of the arrow by the oil pump 2. On the other hand, the air is fed by natural wind in the lower wind tunnel 6.
The insulating oil is taken in through the opening 6a in the cooler 1, and the temperature rises by removing heat from the insulating oil in the cooler 1 section.The density decreases, the air is pushed up by the intake air and accelerated by the chimney effect, and is exhausted from the upper wind tunnel 7. The lower wind tunnel 6 is rotated by wind power and has an opening 6a.
is always facing the direction of the wind, so regardless of the wind direction, natural wind is always taken in and cooled when there is wind. When there is no wind, air is sucked in through the opening 6a of the lower wind tunnel 6 by operating the fan 8, forced air is forced into the cooler 1, and the air is exhausted from the upper wind tunnel 7 by the discharge pressure of the fan 8 and the chimney effect of the upper wind tunnel 7. Ru. As described above, according to the present invention, the lower wind tunnel is arranged at the lower part of the cooler and rotates by wind force so that the opening always matches the wind direction, and the lower wind tunnel is formed in a chimney shape extending from the periphery to the upper part of the cooler. By having an upper wind tunnel and a fan attached to the upper wind tunnel, natural wind is taken in from around the lower part, and after exchanging heat with the oil flowing in the cooling pipe in the cooler section, the chimney effect is used. This system aims to promote air flow by discharging the air to the top, and the opening that takes in the wind is always directed to the wind direction as the wind direction changes, allowing cooling by natural wind when there is wind, and when there is no wind. A fan installed in the upper wind tunnel forcibly inhales air from the bottom, adds a chimney effect, and discharges it to the top.
We were able to provide an energy-saving, highly efficient cooling system for oil-filled electrical equipment that reduces auxiliary equipment loss, reduces noise, and prevents apparent deterioration in cooling performance due to hot air circulation.
