[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1: This embodiment provides an industrial motor high efficiency driver, see Figure 1-4 Specifically, it includes a driver body 1, on which a heat absorption mechanism and an air cooling mechanism are provided;

[0024] The heat absorption mechanism includes a cooling tube 2 and a cooling box 21. The cooling tube 2 is fixedly arranged on the driver body 1. The cooling tube 2 is distributed at the upper and lower ends of the driver body 1 and is in a spiral shape. The cooling box 21 is fixedly arranged on the driver body 1. Both ends of the cooling tube 2 are fixedly connected to one side of the cooling box 21. The cooling tube 2 is connected to the inside of the cooling box 21. A water pump is arranged inside the cooling box 21. The air cooling mechanism includes a plurality of heat dissipation fins 3, a frame 31 and a heat dissipation fan 32. The heat dissipation fins 3 are fixedly arranged on the cooling tube 2. The frame 31 is arranged above the driver body 1. The heat dissipation fins 3 are located in the frame 31. The heat dissipation fan 32 is fixedly arranged in the frame 31. The heat dissipation fan 32 is located directly above the heat dissipation fins 3.

[0025] A water pump is provided inside the cooling box 21 to draw the coolant into the cooling pipe 2. The coolant flows along the cooling pipe 2 to absorb the heat on the surface of the driver body 1. The cooling pipe 2 is distributed in a spiral shape at the upper and lower ends of the driver body 1, contacting the surface of the driver body 1 as much as possible, accelerating the heat exchange between the coolant and the driver body 1, and quickly lowering the surface temperature of the driver body 1. The coolant then transfers the heat to the heat dissipating fins 3. The heat dissipating fins 3 are in full contact with the air and transfer the heat to the air. Finally, the heat dissipating fan 32 draws the air around the heat dissipating fins 3 to the outside of the frame 31, thereby cooling the driver body 1.

[0026] Embodiment 2: Based on Embodiment 1, this embodiment further includes:

[0027] In the specific implementation process, Figure 1 and Figure 4 As shown, a first filter screen 4 is fixedly disposed on the frame 31, a pair of second filter screens 41 are fixedly disposed on the frame 31, a pair of third filter screens 42 are fixedly disposed on the frame 31, two pairs of bolts 5 are inserted on the frame 31, and the bolts 5 are threadedly connected to the driver body 1, and two pairs of mounting holes 6 are opened on the driver body 1;

[0028] The first filter 4, the second filter 41 and the third filter 42 filter the dust outside the frame 31 to prevent the heat dissipation fins 3 from accumulating dust and causing a decrease in the heat dissipation effect. After long-term use, the frame 31 can be disassembled by bolts 5 to clean the filters to ensure the functionality of the filters. The mounting hole 6 is used to fix the driver body 1.

[0029] Specifically, the working principle and operation method of the utility model are as follows:

[0030] A water pump is provided inside the cooling box 21 to pump the coolant into the cooling pipe 2. The coolant flows along the cooling pipe 2 to absorb the heat on the surface of the driver body 1. The cooling pipe 2 is distributed in a spiral shape at the upper and lower ends of the driver body 1 to contact the surface of the driver body 1 as much as possible, thereby accelerating the heat exchange between the coolant and the driver body 1 and quickly reducing the surface temperature of the driver body 1.

[0031] The coolant then transfers the heat to the heat sink fins 3, which are in full contact with the air, transferring the heat to the air;

[0032] The heat dissipation fan 32 draws the air around the heat dissipation fins 3 out of the frame 31, thereby cooling the driver body 1;

[0033] The first filter 4, the second filter 41 and the third filter 42 filter the dust outside the frame 31 to prevent the heat dissipation fins 3 from accumulating dust and causing a decrease in the heat dissipation effect. After long-term use, the frame 31 can be disassembled by bolts 5 to clean the filters to ensure the functionality of the filters.

[0034] As described above, in the present invention, the coolant flows along the cooling pipe to absorb the heat on the surface of the driver body. The cooling pipe is distributed in a spiral shape at the upper and lower ends of the driver body, and contacts the surface of the driver body as much as possible, thereby accelerating the heat exchange between the coolant and the driver body, and quickly lowering the surface temperature of the driver body. The coolant then transfers the heat to the heat dissipation fins, and the heat dissipation fins are in full contact with the air, transferring the heat to the air. Finally, the heat dissipation fan draws the air around the heat dissipation fins out of the frame, thereby achieving the cooling of the driver body, and the cooling effect is good.

[0035] At the same time, the dust is filtered outside the frame through the first filter, the second filter and the third filter to prevent the heat dissipation effect from being reduced due to dust accumulation on the heat dissipation fins. After long-term use, the frame can be disassembled by bolts to clean the filter to ensure the functionality of the filter.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
