The upper cover plate 27 covers the upper end surface formed by the two side plates 24, the inner end plate 25, and the outer end plate 26. In the specific embodiment, the housing 21 is an integral structure except for the upper cover plate, ensuring that the housing 21 is stable and reliable.

[0025] The fan assembly 30 includes an outer shell 31 and at least one set of fans 32 in the outer shell. In a specific embodiment, there are two sets of fans 32, which are arranged horizontally.

[0026] The radiator 20 is fixed to the upper surface of the coil disk mechanism 10. The fan assembly 30 is fixed to the front end of the inner end plate 25 corresponding to the integral structure formed by the combination of the radiator 20 and the coil disk mechanism 10. The upper part of the coil disk mechanism 10 is correspondingly provided with a bottom fin plate 23. The lower surface of the bottom fin plate 23 is provided with a plurality of downwardly protruding heat dissipation fins 231. The upper surface of the bottom fin plate 23 is fixed with a plurality of chip modules 22. The lower surface of the downwardly protruding heat dissipation fins 231 is arranged close to the coil disk cover plate 14. The chip module 22 includes an electrical input interface, a high-voltage output interface, and a low-voltage output interface (the position of the interface is set according to the requirements of the chip module and is omitted here). The inner end plate 25 has a notch 28 at a height corresponding to the downwardly protruding heat dissipation fins 231, and the outer end plate 26 has a plurality of air outlet slots 261 at a height corresponding to the downwardly protruding heat dissipation fins 231. The fan 32 in the fan assembly 30 blows air toward the bottom fin plate 23 through the notch 28 and dissipates hot air through the air outlet slots 261.

[0027] In a specific implementation, the inner end plate 25 is provided with an electrical input port 251 and a fan electrical output port 252. The output end of the excitation wire 12 is connected to the electrical input interface in the radiator 20 through the notch 28 and the electrical input port 252. The outer end plate 26 is provided with a low-voltage output port 262 and a high-voltage output port 263. The high-voltage output interface 263 is electrically connected to the high-voltage output port, and the low-voltage output interface 262 is electrically connected to the low-voltage output port. The low-voltage output interface is also connected to the corresponding fan 32 through an electric wire passing through the fan electrical output port 252, which makes the circuit connection stable, reliable, and convenient.

[0028] The side plate 24 is provided with a first connection hole 241 at the end edge corresponding to the inner end plate 25. The first connection hole 241 is connected to the two side covers 36 of the outer shell 31 of the fan assembly 30 through the L-type connector 1 and a plurality of first bolts 2.

[0029] The bottoms of the two side panels 24 are provided with a plurality of inwardly recessed second connection holes 242. The coil disk cover plate 14 is mounted on the coil disk base 11. Inwardly recessed avoidance grooves 112 are provided on the bottom of the coil disk base 11 at positions corresponding to the second connection holes 242. The second bolts 3 penetrate the coil disk base 11 and the coil disk cover plate 14 at the positions of the inwardly recessed avoidance grooves 112 from bottom to top and are then fixed to the second connection holes 242. This ensures a stable and reliable connection between the coil disk mechanism 10 and the heat sink 20.

[0030] The outer shell 31 of the fan assembly 30 includes an upper end plate 33, a lower end plate 34, a front vertical plate 35, and two side covers 36. The inner end edges of the front vertical plate 35 are respectively provided with an upper end plate 33, a lower end plate 34, and two side covers 36, thereby enclosing a fan installation cavity. The two fans 32 are both fixed in the fan installation cavity, and the air outlets are arranged toward the inner end plate 25. The front vertical plate 35 is provided with an air inlet mesh plate 37 at the position corresponding to the fan 32, which facilitates the reliable passage of wind. In specific implementation, the outer shell 31 is made into an integral structure to ensure stability and reliability.

[0031] In specific implementation, the side of the upper cover plate 27 is further provided with a side protruding connection hole 271, which is used to fix the entire structure and the trolley.

[0032] Its working principle is as follows: the coil disk mechanism at the bottom is equipped with an excitation wire for receiving electricity, and then the electricity is transmitted to several chip modules located in the radiator cavity through the excitation wire. The several chip modules convert the electricity into high-voltage output and low-voltage output, and then output it to the fan, the battery module of the trolley and other power-consuming structures through the corresponding ports. The fan is set at the front end of the overall structure formed by the combination of the radiator and the coil disk mechanism. The fan directly dissipates the heat from the upper surface of the coil disk mechanism and the lower surface of the radiator through air cooling. Since the lower surface of the lower convex heat dissipating fins is in close contact with the coil disk cover, the heat of the coil disk mechanism is also carried away by the wind through the heat dissipating fins, further ensuring the heat dissipation performance. It combines heat dissipation and power reception into an integrated device, which makes the overall volume small and suitable for reliable assembly of warehousing and logistics trolleys.
