Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a high-voltage electric control cabinet that is convenient for heat dissipation, including a cabinet body 1, a side coolant tank 2, an installation mesh panel 3, a bottom coolant tank 4, a heat conduction groove 5, a delivery pipe 6, a micro water pump 7, a return pipe 8, a micro motor 9, a bottom shaft 10, a stirring fan blade 11, a top heat conduction fin 12, a heat dissipation window 13, a heat dissipation fan 14, and a side heat dissipation fin 15. On both sides of the inner wall of the cabinet body 1, a side coolant tank 2 is fixedly installed. On the outer wall of the side coolant tank 2, an installation mesh panel 3 is fixedly installed. On the bottom surface of the installation mesh panel 3, a bottom coolant tank 4 is fixedly installed. On the outer bottom surface of the bottom coolant tank 4, a heat conduction groove 5 is opened. At the front end of the side of the bottom coolant tank 4, a delivery pipe 6 is installed. A micro water pump 7 is installed on the delivery pipe 6. The delivery pipe 6 is connected to the side of the side coolant tank 2. At the front end of the side of the bottom coolant tank 4, a return pipe 8 is installed. The return pipe 8 is connected to the side of the side coolant tank 2. At the edge of the top of the cabinet body 1, a micro motor 9 is installed. The output end of the micro motor 9 is installed with a bottom shaft 10. At the bottom end of the bottom shaft 10, a stirring fan blade 11 is fixedly installed. The top heat conduction fin 12 is installed through the top of the cabinet body 1. A heat dissipation window 13 is opened at the top of the top heat conduction fin 12. A heat dissipation fan 14 is installed at the edge of the top of the cabinet body 1.

[0022] At the connection between the cabinet body 1 and the side coolant tank 2 in this example, a side heat dissipation fin 15 is installed through. The side heat dissipation fins 15 are densely distributed at equal intervals. The above structural design enables the side heat dissipation fins 15 to quickly dissipate the heat contained in the coolant in the side coolant tank 2.

[0023] The length and width of the bottom coolant tank 4 are both greater than half of the length and width of the installation mesh panel 3. The installation mesh panels 3 are distributed at equal intervals. The above structural design enables the bottom coolant tank 4 to quickly export the heat generated during the operation of the equipment on the installation mesh panel 3.

[0024] The heat-conducting grooves 5 are densely distributed at equal intervals on the bottom surface of the bottom coolant tank 4. The front view section of the top surface of the heat-conducting grooves 5 is an arc surface. The heat-conducting grooves 5 can increase the contact area between the bottom coolant tank 4 and the air, and improve the heat-conducting efficiency.

[0025] The delivery pipe 6 and the return pipe 8 are symmetrically distributed about the center of the bottom coolant tank 4. The diameters of the delivery pipe 6 and the return pipe 8 are both greater than half of the inner height of the bottom coolant tank 4. The above structural design enables the bottom coolant tank 4 and the side coolant tank 2 to form a smooth passage through the delivery pipe 6 and the return pipe 8, ensuring the circulating flow of the coolant.

[0026] The length of the heat dissipation window 13 is greater than half of the length of the top heat-conducting fins 12. The top heat-conducting fins 12 are distributed at equal intervals. The above structural design enables air to flow smoothly between the top heat-conducting fins 12, improving the heat dissipation efficiency.

[0027] The cooling fans 14 are symmetrically distributed about the center of the cabinet body 1. The cooling fans 14 are only distributed on one side edge of the top of the cabinet body 1. The above structural design enables the cooling fans 14 to accelerate the air flow speed at the top of the top heat-conducting fins 12, improving the heat dissipation efficiency.

[0028] Working principle: When using this device, the heat generated by the equipment installed on the mounting net plate 3 is conducted through the mounting net plate 3 made of metal and the bottom coolant tank 4 into the coolant in the bottom coolant tank 4. The heat-conducting grooves 5 also come into large-area contact with the air in the cabinet body 1, conducting the heat in the air into the coolant in the bottom coolant tank 4;

[0029] The micro water pump 7 sends the coolant in the bottom coolant tank 4 into the side coolant tank 2 through the delivery pipe 6. The micro motor 9 drives the bottom shaft 10 and the stirring fan blades 11 to rotate rapidly, stirring the coolant in the side coolant tank 2 to make the coolant flow quickly and mix evenly. The heat is dissipated outward through the side heat-dissipating fins 15. Subsequently, the cooled coolant enters the bottom coolant tank 4 through the return pipe 8, and circulates in this way to conduct stable water-cooled heat dissipation;

[0030] At the same time, the top heat-conducting fins 12 conduct the heat in the air in the cabinet body 1 out. The cooling fans 14 blow the air flow through the heat dissipation window 13 to cool the top heat-conducting fins 12, thereby realizing the overall efficient heat dissipation of the cabinet body 1. This is the working principle of this high-voltage electric control cabinet that is convenient for heat dissipation.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
