[0002] With the development of automation and intelligence in factories and home life, more and more electrical appliances have entered our lives. The joint work of these appliances requires a stable voltage to enable each appliance to work normally and bring convenience to people's lives. We often use transformers to transform voltage, current, and impedance, as well as for voltage stabilization and isolation.

[0003] During the operation of the transformer, the electronic components inside it will generate a large amount of heat. If this heat cannot be dissipated in time inside the transformer, the temperature of the transformer will rise, making the transformer unable to work normally and shortening the service life of the transformer. In serious cases, fire and other accidents may even occur, which will bring a lot of inconvenience to residents' electricity use and threaten their lives, health and safety. Utility Model Content

[0004] In order to solve the problem that a large amount of heat is generated by the electronic components inside the transformer during operation, and if this heat cannot be dissipated in time inside the transformer, it will cause the transformer temperature to rise and the transformer to fail to work normally, the present application provides a power electronic equipment transformer cooling device.

Exhaust fans are embedded in the top and bottom surfaces of the equipment cabinet, and heat dissipation vents are provided through the side walls of both sides of the equipment cabinet, and mesh panels are provided inside the heat dissipation vents.

[0007] Preferably, a limiting plate and a fixing plate are respectively provided on both sides of the heat dissipation port, and two limiting plates are provided and fixedly distributed on the side wall of the equipment cabinet in parallel up and down.

[0008] Preferably, the fixed plate is fixedly connected to the equipment cabinet, and a side plate is passed through the fixed plate, a pull plate is provided on the side wall of the side plate, and a hydraulic cylinder is provided on the wall opposite to the pull plate, and the output end of the hydraulic cylinder passes through the fixed plate and extends outward to connect with the pull plate.

[0010] Preferably, a stand is provided on the bottom surface of the rectangular plate located below.

[0011] In summary, this application has the following beneficial technical effects:

[0012] 1. Place the transformer inside the equipment cabinet. The exhaust fans on the top and bottom of the equipment cabinet will draw the hot air from the equipment cabinet into the rectangular frame, and then exhaust it through the vents on the rectangular frame. In this way, the hot air generated by the operation of the transformer in the equipment cabinet can be simultaneously drawn out from the top and bottom to the outside of the equipment cabinet, quickly achieving cooling of the transformer in the equipment cabinet.

[0013] 2. The setting of two mesh panels can not only prevent external dust from entering the equipment cabinet and causing damage to the transformer parts inside the equipment cabinet, but also enable the equipment cabinet to form up, down, left and right convection wind, greatly accelerating the heat dissipation and cooling speed of the equipment cabinet.
