Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a heat dissipation device for electrical equipment. Background Art

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role that electricity plays in our lives and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most critical factor for the normal operation and transmission of electricity in the power plant is the electrical equipment. During the use of electrical equipment, long-term work will cause a large amount of heat to accumulate inside the electrical equipment. If it is not discharged in time, it will cause damage to the electrical equipment. Therefore, a heat dissipation device is needed; the heat dissipation device of some existing electrical equipment is to blow refrigerated air into the electrical equipment body, contact with the internal heat to achieve a cooling effect, and discharge the hot gas through the notch to ensure the circulation of the gas, but because the refrigerated air is directly discharged through one side of the electrical equipment body, it cannot effectively contact the electrical equipment body, and the cooling effect is poor, which is not conducive to the heat dissipation efficiency of the device. Utility Model Content

[0003] In view of this, the utility model provides a heat dissipation device for electrical equipment, which can not only realize the circulation of gas in the electrical equipment body, but also provide sufficient and effective cooling contact to the electrical equipment body through the side of the electrical equipment body, thereby ensuring the cooling effect and being beneficial to the heat dissipation efficiency of the device.

[0004] In order to solve the above technical problems, the utility model provides a heat dissipation device for electrical equipment, comprising an electrical equipment body, a connection box is arranged at the left end of the electrical equipment body, and cooling and heat dissipation components are arranged inside the electrical equipment body and the connection box;

Then the staff can start the fan to suck the outside air into the connection box, and blow it into the air supply duct after it contacts the refrigeration plate. Then it is discharged into the cold air cavity through the through hole. Then the cooling air will be diverted to the interior of the electrical equipment body through the air outlet duct, and finally discharged through the exhaust port to contact the interior of the electrical equipment body to achieve cooling operations. As the cooling air is blown out, it can also drive the air with heat to be discharged outward through the baffle, thereby increasing the heat dissipation effect.

[0006] A filter is provided at the left end of the connection box, and the filter can filter the air sucked into the connection box and block dust outside the filter.

[0007] The baffles are evenly distributed in a grid shape, and the air inside the electrical equipment body can be discharged to the outside through the grid.

[0008] The air outlet ducts are respectively located on the left, right and rear side walls inside the electrical equipment body, ensuring that the cooling air is fully in contact with the interior of the electrical equipment body.
