[0021] The fixing mechanism is symmetrically arranged on both sides of the main frame, and the fixing mechanism includes a fixing sleeve, a sliding shaft and a clamping plate. The fixing sleeve is fixed on the main frame, the sliding shaft passes through the fixing sleeve and the end is connected to the clamping plate, and the fixing sleeve locks and fixes the sliding shaft.

[0022] Furthermore, the main frame is provided with a mounting hole, and the semiconductor refrigeration plate is connected to the heat conducting plate through the mounting hole.

[0023] Furthermore, a locking assembly is provided on the fixing sleeve, and the locking assembly includes a nut and a bolt knob. The nut is fixed on the fixing sleeve, and the bolt knob is threadedly connected to the nut and the end thereof passes through the side wall of the fixing sleeve and contacts the sliding shaft.

[0024] Furthermore, a limiting ring is provided on the main frame, and the end of the sliding shaft on one side of the main frame passes through the limiting ring and is limited by it.

[0025] Furthermore, the splint is a rubber plate.

[0026] The inverter is a V / f controlled inverter.

[0027] A cooling device for an iron ore inverter includes a main frame 1, a controller 2, a heat conducting plate 3, a radiator 4 and a fixing mechanism 5; the heat conducting plate 3 is fixed to the inner side of the main frame 1, the controller 2 is fixed to the main frame 1 and electrically connected to the radiator 4 for opening and closing the radiator 4, the radiator 4 is fixed to the outer side of the main frame 1, the radiator 4 includes a cooling fan 401 and a semiconductor refrigeration plate 402, the semiconductor refrigeration plate 402 is fixed to the heat conducting plate 3, the cooling fan 401 is fixed to the semiconductor refrigeration plate 402, and the heat exchange between the inverter and the semiconductor refrigeration plate 402 is realized through the heat conducting plate 3, thereby cooling the inverter, and the cooling fan 401 rotates to further cool the inverter.

[0028] The fixing mechanism 5 is symmetrically arranged on both sides of the main frame 1. The fixing mechanism 5 includes a fixing sleeve 501, a sliding shaft 502 and a clamping plate 503. The fixing sleeve 501 is fixed on the main frame 1. The sliding shaft 502 passes through the fixing sleeve 501 and the end is connected to the clamping plate 503. The clamping plate 503 contacts the side wall of the inverter. After pulling the sliding shaft 502 to clamp the clamping plate 503 to clamp the inverter, the fixing sleeve 501 locks the sliding shaft 502 to prevent the cooling device from slipping.

[0029] In one embodiment of the present application, in order to enable the semiconductor refrigeration plate 402 and the heat conducting plate 3 to better achieve heat transfer and cooling, a mounting hole 101 is provided on the main frame 1, and the semiconductor refrigeration plate 402 is connected to the heat conducting plate 3 through the mounting hole 101. The two are in direct contact, and the heat dissipation effect is better.

[0030] In one embodiment of the present application, in order to effectively fix the sliding shaft 502, a locking assembly 504 is provided on the fixing sleeve 501, and the locking assembly 504 includes a nut 5041 and a bolt knob 5042. The nut 5041 is fixed on the fixing sleeve 501, and the bolt knob 5042 is threadedly connected to the nut 5041 and the end thereof passes through the side wall of the fixing sleeve 501 and contacts the sliding shaft 502. The sliding shaft 502 is fixed by the pressure of the bolt knob 5042, thereby ensuring that the clamping of the splint 503 will not loosen.

[0031] In one embodiment of the present application, a limiting ring 505 is further provided on the main frame 1, and the end of the sliding shaft 502 on one side of the main frame 1 passes through the limiting ring 505 and is limited by it; after the sliding shaft 502 passes through the fixing sleeve 501 and continues to extend, the extended part will be offset due to the action of gravity, thereby causing uneven force on both ends of the fixing sleeve 501 and causing damage to it. The limiting ring 505 limits the end of the sliding shaft 502 to ensure that it is always in a horizontal state, making it more convenient to slide and more evenly stressed.

[0032] The clamping plate 503 is a rubber plate, which makes the contact between the clamping plate 503 and the inverter more firm, has greater friction, and is not easy to slip off.

[0033] The sliding shaft 502 is connected to the splint 503 through the fixing frame 506. A reinforcement plate 507 is provided on the outside of the fixing frame 506. The fixing frame 506 extends the position of the splint 503 so that it can contact the main body of the inverter, with a larger contact area. The reinforcement plate 507 can effectively increase the strength of the connection to prevent it from being damaged.

[0034] There are several radiators 4 evenly arranged on the main frame 1. The larger the number, the larger the contact area and the better the heat dissipation effect. The number of radiators 4 can be adjusted according to the actual model of the inverter to achieve the best heat dissipation effect.

[0035] The specific implementation process of the iron ore inverter cooling device of the present invention is as follows: a heat conducting plate 3 is installed on the rear side of the main frame 1 and a mounting hole 101 is punched, and the radiator 4 is installed in the mounting hole 101 to ensure that its semiconductor refrigeration plate is in direct contact with the heat conducting plate 3; after the radiator 4 is installed, the sliding shaft 502 is pulled to make the clamping plate 503 close to the side wall of the inverter, while ensuring that the heat conducting plate 3 is close to the inverter body. After adjusting the position, the sliding shaft 502 is locked by rotating the bolt knob 5042, thereby realizing the overall fixation of the cooling device, and the radiator 4 is turned on by the controller 2 to cool the inverter in the iron ore to ensure that it can operate smoothly in the environment.

[0036] The above description is only a specific embodiment of the present invention, but the structural features protected by the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
