The invention relates to heat exchange using heat pipes and can be used in the energy sector of all branches of the national economy.

The purpose of the invention is to increase the system efficiency by increasing the efficiency of transformer heat utilization.

FIG. 1 shows a device for cooling transformer oil; in fig. 2 is a view A-A in FIG. one ;

in fig. 3 is a section BB in FIG. one.

The device contains an oil tank

I, in which the iron core and transformer windings (not shown), the expander 2, the safety pipe 3, the high voltage input 4, the low voltage input 5, the switch actuator 6, the carriage 7, the heat exchangers 8 (one on both sides of the tank 1) connected to the tank

1 by means of oil pipes 9 with embedded pumps 10, heat pipes

I1, the evaporating ends 12 of which are placed in the vessels 8, and the condenser ends 13 are inserted into the air pipe 14. In the pipe 14 there are placed the impeller 15 of the wind turbine and the generator 16 of electric current connected to each other. In the wall of the pipe 14 opposite the impeller there are windows 17, to which the nozzles adjoin

Tangential to the cross section of the pipe, -js y, exposed to atmospheric forces. The grids 18 are installed at the entrance to the windows.

The system works as follows.

When a transformer is put into operation, its windings and steel core are heated. They heat up the oil, which fills the oil tank 1. Part of the oil is displaced into the expander 2. The oil heated in the tank 1 is fed through the upper oil lines 9 by means of the pumps 10 of the heat exchanger 8 (one on each side of the tank 1). In them, heat is transferred to the heated oil through the walls of the evaporating ends of 12 heat pipes.

deflector 19. The windows 17 for supplying external air to the air tube are covered with nets 18 to prevent foreign objects from getting onto the impeller 15 of the wind turbine. In order to, v reduce unproductive heat losses, heat exchangers 8, middle sections of heat pipes 11 and walls of the air pipe 4 above entering heat pipes into it are covered with a layer of thermal insulation. The use of the proposed system will increase the efficiency by increasing the efficiency of heat utilization, save electric energy by eliminating the forced cooling of the oil cooler using a fan and return 1. part of the energy consumed to the own electricity supply system of the 11 liquid 20 that starts to cool. 55 business enterprises sing. The vapor of liquid 20 moves to the upper (condenser) ends of the heat pipes, gives them warmth to the cold walls and condenses.

Claims (2)

1. System for using transformer containing 3670542 flow down. Cooled in heat exchangers 8, the oil through the lower oil lines 9 enters again into the tank 1. The heated condenser ends 13 are heated. exhaust pipes give their heat to the air in the air pipe 14. Since the heated air has a lower density than cold air, it 10 is the last to be pushed up. The place of heated air is occupied by new portions of cold air coming in through windows 17 in the lower part of the tube 14. Due to the fact that narrowing nozzles adjoin windows 17, the air picks up speed at the exit of them. Jets of air fall on the working blades of the impeller 15 and bring it into rotational motion. In this case, the net energy of the air is transferred to the mechanical energy of the wind turbine transmitted to the electric current generator 16. It converts mechanical energy into electrical. Electric current from the generator 16 is supplied to the consumer, for example, on the charging of the battery. In this way, a part of the heat energy released by the transformer is transferred back into electric and effective cooling of the oil in the tank 1 without forced blowing with the help of a fan. The top of the air pipe 14 is protected by atmospheric exposure by the deflector 19. The windows 17 for supplying external air to the air pipe are covered with nets 18 to prevent foreign objects from getting on the impeller 15 of the wind turbine. In order to, v reduce unproductive heat losses, heat exchangers 8, middle sections of heat pipes 11 and walls of the air pipe 4 above entering heat pipes into it are covered with a layer of thermal insulation. The use of the proposed system will increase the efficiency by increasing the efficiency of heat utilization, save electrical energy by eliminating the forced blowing of the oil cooler using a fan and return 1. part of the energy lost to the power supply system of its own needs.
