DETAILED DESCRIPTION

[0013] The utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0016] The heat dissipation device 5 includes a first ventilation waveguide window 12, an air filter element 13, a cooling fan 14, a mounting bracket 15, a temperature sensor 16, a one-way valve 17, and a second ventilation waveguide window 18. The air filter element 13 is installed at the left end of the first ventilation waveguide window 12, the cooling fan 14 is installed at the left end of the air filter element 13, the mounting bracket 15 is installed at the left end of the cooling fan 14, the mounting bracket 15 is fixed to the top inner side of the power regulator body 1 by screws, and a temperature sensor 16 fixed by screws is installed in the middle of the bottom end, and a one-way valve 17 is installed at the left end of the mounting bracket 15. The one-way valve 17 is a four-sided rectangular structure with a hinged inclined baffle installed on the inside and a second ventilation waveguide window 18 fixed by screws is installed on the left end.

[0017] The working principle of the utility model is: first, the outer shell and the cabinet door structure on the surface of the power regulator body are the same and both use aluminum plates and copper foil to reduce the electromagnetic interference propagation effect, and then the aluminum plates and copper foil are protected by internal and external PVC plates, and then the fan of the heat dissipation device drives the air circulation inside and outside the power regulator body and the first and second waveguide ventilation windows are used to ensure the anti-electromagnetic interference effect during air circulation and the impurities in the air are filtered through the air filter element, and then the temperature inside the power regulator body is detected by the temperature sensor. At the same time, the one-way valve can ensure that the air circulation always maintains the effect of entering from the right end and exhausting from the left end (the inclined baffle hingedly connected inside the one-way valve contacts the bottom plate inside the one-way valve under the action of gravity when the cooling fan is not working to prevent air and dust from entering the inside of the power regulator body through the second ventilation waveguide window, and then when the cooling fan is started, the thrust generated in the air circulation drives the inclined baffle to rotate so that the air can enter the second ventilation waveguide window and then be discharged from the inside of the power regulator body).

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, replacements and variations made to the implementation methods are still within the scope of protection of the present invention.
