[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0034] The lower shell assembly 23 includes a central shell 231 and an edge shell 233, and a plurality of edge shells 233 are connected to the central shell 231. The cooling assembly 24 includes a medium cooling device 241 and a medium circulation part 242, and the medium cooling device 241 is connected to the medium circulation part 242. The medium circulation part 242 is installed in the edge shell 233.

[0035] The rotating part 22 includes a driving motor 221 and a rotating shell 223 . The driving motor 221 is in transmission connection with the rotating shell 223 . The water absorbing member 25 is embedded in the rotating shell 223 . The rotating shell 223 is movably sleeved on the outer side of the upper shell assembly 21 .

[0036] Furthermore, the lower shell assembly 23 also includes an air duct 232 and a dustproof mesh hole 234 . The air duct 232 is fixedly connected between the central shell 231 and the edge shell 233 . A dustproof mesh hole 234 is provided between the edge shell 233 and the air duct 232 .

[0037] Furthermore, the rotating part 22 also includes a driving gear 222, an annular groove 224, a vent 225 and meshing teeth 226. The driving motor 221 is connected to the driving gear 222.

The water absorbent 25 is embedded in the annular groove 224. The side of the rotating shell 223 is provided with a vent 225. When the driving motor 221 drives the rotating shell 223 and the water absorbent 25 to rotate through the driving gear 222 and the meshing teeth 226, the air can pass through the water absorbent 25 evenly through the vent 225 instead of concentrating on a certain area of ​​the water absorbent 25, thereby maximizing the utilization rate of the water absorbent 25. The water absorbent 25 is made of sponge, which can absorb moisture in the air and filter dust and impurities in the air.

[0038] Furthermore, the upper shell assembly 21 includes an upper shell 211, a second ventilation hole 212, a third ventilation hole 213 and a bracket 214.

[0039] Furthermore, the frequency converter cabinet housing assembly 1 also includes an air collecting hood 141, a cabinet door 15, and a base 16. The cabinet door 15 is movably connected to the surface of the cabinet body 11, the air collecting hood 141 is fixedly connected to the bottom of several exhaust ducts 14, and the base 16 is fixedly connected to the bottom of the cabinet body 11.

[0040] In the embodiment of the present invention, a temperature sensor for monitoring the internal temperature is also installed in the cabinet 11, and electronic components and wires are installed on the surface of the mesh plate. The negative pressure generated when the cooling fan is working first drives the outside air into the edge shell 233 through the air inlet mesh, and then enters the annular groove 224 along the dustproof mesh 234 and the air duct 232. The air then passes through the water absorbent 25 and the vent 225 to enter the mesh plate, thereby cooling the electronic components and wires installed on the surface of the mesh plate. In this process, the dustproof mesh 234 and the water absorbent 25 both play a dustproof role, and the water absorbent 25 can also absorb moisture in the air in a humid environment.

[0041] See also Figures 1 to 14In one embodiment of the present invention, the medium circulation part 242 includes a cold medium inlet pipe 2421, a hollow tube 2422, an annular tube 2423 and a hot medium outlet pipe 2424, and a plurality of the hollow tubes 2422 are fixedly connected with an annular tube 2423, the hollow tubes 2422 on one side of the medium circulation part 242 are fixedly connected with the cold medium inlet pipe 2421, and the hollow tubes 2422 on the other side of the medium circulation part 242 are fixedly connected with the hot medium outlet pipe 2424.

[0042] Furthermore, the cooling component 24 also includes a first circulation pipe 243 and a second circulation pipe 244 , wherein the first circulation pipe 243 is connected between the cold medium inlet pipe 2421 and the medium cooling device 241 , and the second circulation pipe 244 is connected between the hot medium outlet pipe 2424 and the medium cooling device 241 .

[0043] In an embodiment of the present invention, when the outside air enters between the plurality of hollow tubes 2422 and the annular tube 2423 through the air inlet mesh, the cold medium flowing in the plurality of hollow tubes 2422 and the annular tube 2423 can sufficiently and quickly cool the air and cause the moisture in the air to condense on the surface of the hollow tube 2422 and the annular tube 2423 in the form of water droplets.

[0044] Working principle: When the air passes through the upper end of the exhaust duct 14, the negative pressure generated first drives the outside air into the bottom of the cabinet 11 through the air intake grille 13, then into the edge shell 233, and then into the annular groove 224 along the dustproof mesh 234 and the air duct 232. The air then passes through the water absorbent 25, the vent 225, and the second ventilation hole 212 into the upper shell 211, and then enters the air collecting cover 141 through the third ventilation hole 213 and the first ventilation hole 121, and is finally discharged from the upper end of the exhaust duct 14, thereby cooling the electronic components and wires installed above the partition plate 12. In this process, the dustproof mesh 234 and the water absorbent 25 both play a role in dust prevention, and the water absorbent 25 can also absorb moisture in the air in a humid environment.

[0045] When the frequency converter cabinet is working at high load, the medium cooling device 241 transports the cold medium to the several hollow tubes 2422 and the annular tube 2423 through the first circulation pipe 243 and the cold medium inlet pipe 2421, and then enters the medium cooling device 241 through the hot medium outlet pipe 2424 and the second circulation pipe 244 for circulation refrigeration. Based on the above principle of using air flow for cooling in the frequency converter cabinet, when the outside air enters between the several hollow tubes 2422 and the annular tube 2423 through the air intake grille 13 and the edge shell 233, the cold medium flowing in the several hollow tubes 2422 and the annular tube 2423 can fully and quickly cool the air, and make the moisture in the air condense on the surface of the hollow tube 2422 and the annular tube 2423 in the form of water droplets, thereby achieving the purpose of quickly cooling the electronic components and wires on the surface of the mesh plate.

[0046] To summarize, the intelligent heat dissipation system 2 arranged between the bottom of the cabinet 11 and the partition plate 12 utilizes the negative pressure generated when the air passes through the upper end of the exhaust duct 14 and reduces the temperature of the flowing air to quickly cool down the electronic components and wires on the surface of the mesh plate, while also being able to remove moisture and dust from the air. In addition, the intelligent heat dissipation system 2 is relatively small in size and will not occupy a large amount of space in the frequency conversion cabinet. It has the characteristics of strong practicality, good cooling effect and small size.
