Conventionally, there is an evaporative cooling type transformer that cools an iron core or windings by spraying an evaporative refrigerant such as fluorocarbon onto the core or windings. This uses the latent heat of evaporation when the sprayed refrigerant touches the iron core and windings to evaporate.The evaporated refrigerant is led to a radiator and radiates heat, and at the same time condenses and liquefies and becomes the sprayed liquid again. used.

It is pumped up through piping 7 and sprayed onto iron core 1 and winding 2 from above. Note that the space A within the tank 3 is filled with an insulating gas, and a non-condensable gas such as SF 6 is used as the insulating gas.

し、冷却には殆んど寄与しない。 Next, its effect will be explained. When the refrigerant fluorocarbon liquid 5 sprayed on the heated iron core 1 and winding 2 evaporates due to the heat, it absorbs the heat loss of the iron core 1 and the winding 2 as accumulated heat of evaporation and evaporates. Since this vaporized fluorocarbon vapor has a higher specific gravity than SF 6 gas, which is an insulating gas, it gathers at the bottom of the tank and enters the radiator 4 through the lower communication section.
The fluorocarbon vapor that has entered the heat radiator 4 radiates heat, is cooled, and is condensed and liquefied again. On the other hand, the insulating gas collects and stagnates above the tank 3 and the radiator 4, and hardly contributes to cooling.

Since the conventional evaporative cooling transformer is configured as described above, heat is radiated only in the part of the radiator 4 where the fluorocarbon enters, and in the part above the radiator where the insulating gas accumulates. 4. Heat is no longer supplied to the heat transfer surface. Therefore, in an evaporative cooling type transformer with such a configuration, the heat dissipation effect at the top of the radiator is extremely poor, resulting in poor cooling performance. Methods have been used in which the fluorocarbon vapor is forcibly moved to the upper part of the radiator, but each method has problems such as increasing the space for installing the radiator and increasing the number of auxiliary equipment.

The heat is sent to the top of the radiator through the heat pipe, and the heat is radiated to the air outside the device through the entire radiator.
Cooling performance is significantly improved.

An embodiment of this invention will be described below with reference to the drawings. In FIG. 1, 1 to 7 are exactly the same as those in FIG. 2 above. Reference numeral 8 denotes a heat pipe, one end of which is disposed below the radiator 4 and the other end thereof above the radiator 4, and is attached so as to exchange heat with the radiator 4. At least one heat pipe 8 is attached to the heat sink of the heat sink 4. Note that the lower part of the part that communicates between the radiator 4 and the tank 3 is provided on the side wall of the tank 3, but the upper part does not necessarily need to be provided on the side wall.
As shown in the figure, communication may be made from the tank ceiling.
In this way, the height of the radiator can be increased, the effect of the heat pipe can be used more effectively, and the space in which the radiator is installed can be reduced.

要因となる。 Next, its effect will be explained. The fluorocarbon liquid 5 spread over the iron core 1 and the winding 2 absorbs heat loss from the iron core 1 and the winding 2 and evaporates as in the conventional case. Since this vaporized fluorocarbon vapor is heavier than SF 6 gas, it collects at the bottom of the tank and is sent to the radiator 4 through a communication pipe at the bottom of the tank. At the bottom of the radiator 4, heat is exchanged with the incoming fluorocarbon, the fluorocarbon is condensed and liquefied, and returned to the bottom of the tank. The lower part of the radiator heated by heat exchange with the fluorocarbon radiates a part of the heat into the air, and the rest is transported to the upper part of the radiator by the heat pipe 8, and is released from the upper part of the radiator into the air. Dissipates heat from the navel. As a result, although the heat transfer area from the fluorocarbon to the radiator remains the same as before, the heat transfer area from the radiator to the air is significantly increased by using the heat pipe. Heat transfer from the fluorocarbon to the radiator, which is generally performed by condensation of the fluorocarbon, has a higher heat transfer coefficient than heat transfer from the radiator to the air, so the cooling performance of the radiator depends on the heat transfer area on the air side. It depends greatly on the situation. Therefore, by using a heat pipe, the heat transfer area on the air side can be increased, which is a major factor in increasing the cooling performance of the radiator.
