[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 A heat dissipation base plate for power equipment includes a base plate 1. The lower end face of the base plate 1 has four heat absorption zones 9 arranged in an array. Each heat absorption zone 9 is provided with heat dissipation columns 3 at equal intervals. A U-shaped guard plate 6 is provided on the lower end face of the base plate 1 and outside the four heat absorption zones 9. A cooling mechanism is provided on the U-shaped guard plate 6. The four ends of the base plate 1 are at predetermined distances from the four heat absorption zones 9 in both the horizontal and vertical directions.

[0021] Both ends of the base plate 1 are provided with extensions 2, and both ends of the two extensions 2 and the other two ends of the base plate 1 are provided with connecting holes 10.

[0022] The cooling mechanism includes two strip holes 8 symmetrically opened on the horizontal section of the U-shaped guard plate 6, and cooling fans 7 are evenly spaced at the two strip holes 8. Auxiliary ventilation holes 5 are evenly spaced on the horizontal section of the U-shaped guard plate 6.

[0023] The outer wall of the cooling fan 7 is provided with a connecting ear 14, which is connected to the U-shaped guard plate 6 by bolts, making it easy to disassemble and install the cooling fan 7.

[0024] Temperature sensor 15 and controller 16 are installed on the inner wall of U-shaped guard plate 6. Cooling fan 7 and temperature sensor 15 are both electrically connected to controller 16.

[0025] Both ends of the lower horizontal section of the U-shaped guard plate 6 are bolted to U-shaped supports 4, which provide support for the U-shaped guard plate 6.

[0026] The power equipment is placed on the base plate 1, and bolts are used to connect the power equipment to the base plate 1 through some of the connection holes 10. The remaining connection holes 10 can be used to connect to the external frame with bolts. The base plate 1 transfers the heat generated by the power equipment to the heat dissipation columns 3. The vertical array heat dissipation column 3 layout replaces the traditional planar heat sink, thereby increasing the heat flux density within the limited area of ​​the base plate 1.

[0027] Temperature sensor 15 detects the temperature of heat dissipation column 3 and transmits the temperature information to controller 16. When the temperature is too high, controller 16 controls cooling fan 7 to turn on, using cooling fan 7 to blow cold air from the outside towards heat dissipation column 3 to assist heat dissipation column 3 in heat dissipation, thereby conducting the heat generated by the power equipment to the outside more quickly.

[0028] Example 2 is an optimization based on Example 1, specifically:

[0029] The base plate 1 has a serpentine flow channel 13 inside. The two ends of the serpentine flow channel 13 are respectively provided with a liquid inlet connector 11 and a liquid outlet connector 12. Both the liquid inlet connector 11 and the liquid outlet connector 12 are connected to the external coolant circulation pipeline.

[0030] By allowing the coolant to flow through the serpentine channel 13, the coolant can further carry away the heat absorbed by the base plate 1, thereby improving the thermal conductivity and contributing to the stable operation of the power equipment.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
