[0002] A power control cabinet is to assemble switch equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements of the normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment. When operating normally, the circuit can be switched on or off manually or automatically.

[0003] When the power control cabinet is in use, a large amount of heat will be generated due to the operation of the internal electrical components. Therefore, the power control cabinet is usually equipped with a heat dissipation mechanism. At present, the heat dissipation function of the existing control cabinet heat dissipation mechanism is relatively single, mostly natural air cooling. Therefore, when used in a high-temperature environment, natural air cooling cannot meet the heat dissipation requirements of the control cabinet, resulting in easy overheating and damage of the internal electrical components of the control cabinet.

A cover plate 6 is fixedly connected to the top surface of the water storage tank 5. A water injection pipe 7 is fixedly connected to the inner wall of the cover plate 6. A solenoid valve 8 is fixedly connected to the inner wall of the water injection pipe 7. A refrigeration mechanism is arranged inside the water storage tank 5. The refrigeration mechanism is composed of a semiconductor refrigeration sheet 9, an air hood 10 and a heat dissipation fan 11. The semiconductor refrigeration sheet 9 is fixedly connected to the inner wall of the water storage tank 5. The air hood 10 is fixedly connected to the back surface of the water storage tank 5. The heat dissipation fan 11 is fixedly connected to the inner wall of the air hood 10, used for reducing the temperature of the coolant, facilitating the reduction of the air temperature through low-temperature conduction, and improving the heat dissipation efficiency. A circulation component is arranged inside the water storage tank 5. A suction mechanism is arranged inside the main body 1 of the control cabinet. A switch door component is arranged on the left side of the main body 1 of the control cabinet.

[0022] Specifically, the circulation component is composed of a circulation pipe 12, a water pump 13 and a cold conduction plate 14. The circulation pipe 12 is fixedly connected to the inner wall of the water storage tank 5, and the circulation pipe 12 is fixedly connected to the inner wall of the fixed frame 3. The water pump 13 is fixedly connected to the inner wall of the circulation pipe 12, and the water pump 13 is fixedly connected to the surface of the water storage tank 5. The cold conduction plate 14 is fixedly connected to the inner wall of the fixed frame 3, and the inner wall of the cold conduction plate 14 is fixedly connected to the surface of the circulation pipe 12, used for driving the low-temperature coolant to circulate, facilitating the circulation cooling work of the air, and improving the stability of cooling and heat dissipation.

[0023] Specifically, the suction mechanism is composed of an air duct 15, an air outlet grille 16, and a suction fan 17. The air duct 15 is fixedly connected to the inner wall of the control cabinet main body 1. The air outlet grille 16 is fixedly connected to the top surface of the air duct 15. The suction fan 17 is fixedly connected to the inner wall of the air duct 15, and is used to suck out the air and heat inside the control cabinet main body 1, facilitating the heat dissipation work adapted to different ambient temperatures.

[0024] Specifically, the switch door assembly is composed of a hinge 18, a door panel 19, and a door lock 20. The hinge 18 is fixedly connected to the left side of the control cabinet main body 1. The door panel 19 is hingedly installed on the control cabinet main body 1 through the hinge 18. The door lock 20 is fixedly connected to the inner wall of the door panel 19, and is used to open and close the control cabinet main body 1, facilitating the installation and maintenance of electrical components.

[0025] All the electrical components mentioned in this article are electrically connected to an external main controller and 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0026] When in use: First, open the solenoid valve 8 to inject the coolant into the water storage tank 5 through the water injection pipe 7. After opening the door lock 20, turn the door panel 19 open through the hinge 18, and various electrical components can be installed into the control cabinet main body 1. Reset and close the door panel 19 and the door lock 20 to seal and protect the control cabinet main body 1. When starting, first start the suction fan 17 to suck out the air and heat inside the control cabinet main body 1 through the air duct 15 and discharge it through the air outlet grille 16. At the same time, the external air enters the control cabinet main body 1 through the fixed frame 3 and the air inlet grille 4, and the heat dissipation work of the internal electrical components can be carried out. When the external ambient temperature is too high, start the semiconductor refrigeration sheet 9 for heat absorption and heat release work. The heat absorption end of the semiconductor refrigeration sheet 9 absorbs the heat inside the water storage tank 5 to reduce the coolant temperature. Start the heat dissipation fan 11 to dissipate heat from the heat release end of the semiconductor refrigeration sheet 9. Start the water pump 13 to suck the low-temperature coolant and circulate it along the inner wall of the circulation pipe 12. At the same time, transfer the low temperature of the coolant to the cold conduction plate 14 through the circulation pipe 12. When the external air enters and contacts the cold conduction plate 14 in the fixed frame 3, the air temperature can be reduced. When the low-temperature air enters the control cabinet main body 1, the electrical components can be quickly cooled down by heat dissipation.

[0027] In summary, for the adjustable heat dissipation type electric control cabinet, the solenoid valve 8 is opened to inject the coolant into the water storage tank 5 through the water injection pipe 7, the control cabinet main body 1 is sealed and protected by the switch door assembly, the suction mechanism is started to perform the suction heat dissipation work on the inside of the control cabinet main body 1. When the external environmental temperature is too high, the refrigeration mechanism is started to reduce the temperature of the coolant, and the circulation assembly is started to suck the low-temperature coolant to circulate in the fixed frame 3. When the external air enters the fixed frame 3 and contacts the circulation assembly, the air temperature can be reduced to perform the rapid heat dissipation and cooling work, achieving the goal of easily adapting to different environmental temperatures by adjusting the heat dissipation method of the electric control cabinet, avoiding the problem that the control cabinet is prone to overheating and damage in a high-temperature environment due to the relatively single heat dissipation function of the existing control cabinet, and is used to solve the problems raised in the above-mentioned background technology.
