[0001] This utility model relates to the field of transformer oil tank heat dissipation technology, and in particular to an oil-immersed transformer oil tank that improves heat dissipation effect. Background Technology
[0002] The transformer oil tank is the installation base for the transformer oil conservator. It is a pressure vessel constructed by welding steel plates. The oil conservator is installed horizontally on top of the tank to adjust the oil level. The oil conservator adopts a capsule-type, diaphragm-type, or corrugated structure, which can effectively isolate the oil from contact with air and slow down the deterioration of the oil quality. The oil tank and the oil conservator are connected by metal pipes, and a gas relay is installed between them to realize fault detection.
[0003] The oil tank of an oil-immersed transformer mainly consists of the tank body, radiator, and sealing device. The tank body is usually welded from steel plates, which has good sealing performance and mechanical strength. It is mainly used to hold transformer oil and install components such as iron core and windings. The radiator is installed around the tank and usually includes heat dissipation frame, heat dissipation fins, and heat conduction base. It is connected by ventilation base and air guide cover to enhance the heat dissipation effect. The sealing device ensures that the transformer oil inside the tank will not leak, while preventing external moisture and dust from entering the tank.
[0004] The existing oil-immersed transformers use a heat sink consisting of a heat dissipation frame, heat sink fins, and heat conduction base on the oil tank. This single heat dissipation method results in poor heat dissipation in high-temperature environments, which can affect the stability of the oil tank operation of the oil-immersed transformer.
[0005] Therefore, it is necessary to provide an oil-immersed transformer tank with improved heat dissipation to solve the above-mentioned technical problems. Utility Model Content

The other end of the heat-conducting pipe is fixedly connected to a return pipe. The nozzle is located at the bottom of the distribution frame, and the nozzle and the perforation are positioned correspondingly. The return pipe is connected to one side of the transformer tank body at the bottom.
[0008] Preferably, the shock-absorbing base frame includes a base plate, a fixing plate, and shock-absorbing components, wherein the fixing plate is used to mount the shock-absorbing components on top of the base plate; Shock-absorbing components can filter vibrations and improve the shock absorption effect.

[0013] Compared with related technologies, the oil-immersed transformer tank with improved heat dissipation provided by this utility model has the following beneficial effects: This invention provides an oil-immersed transformer tank with improved heat dissipation. To enhance the heat dissipation of the oil-immersed transformer tank, a dedicated conveying assembly and heat-conducting pipes are used to extract the cooler oil from the bottom of the tank. The oil is then conveyed through a conveying pipe to a distribution frame with nozzles. The nozzles spray the oil from the top of the tank. During external circulation, air cooling is used to further enhance heat dissipation, allowing the oil to circulate within the tank and improving its overall heat dissipation. Meanwhile, inside the oil-immersed transformer tank... The installation of the first and second turbulence components, working together, can evenly mix the sprayed oil into the oil tank of the oil-immersed transformer. This design divides and redirects the relatively stable oil flow as it passes through the turbulence components, creating a complex turbulent flow state.
