[0002] People's life is inseparable from electricity. The use of electricity has greatly facilitated people's life. In the process of power transmission, transformers are often needed to increase or decrease the voltage, so as to facilitate the long-distance transmission of electricity or the transmission into thousands of households. Transformers are generally immersed in oil, so an oil tank is needed to store the oil, so as to facilitate the use of transformers. During the use of transformers, heat will be generated, and the oil in the transformer oil tank will also play a role in heat dissipation. The oil transfers the heat generated by the transformer to the outer shell of the oil tank and dissipates the heat out of the transformer. The existing transformer oil tanks generally dissipate heat through radiators. The existing radiators are generally fixedly arranged on the outer side of the oil tank. During the transportation of the oil tank, the radiators are easily bent and damaged, affecting the subsequent use of the entire oil tank. At the same time, the existing transformer oil tanks only dissipate heat from the side wall of the oil tank through radiators, lacking a heat dissipation structure for the bottom of the oil tank, so that the heat accumulated at the bottom of the oil tank cannot be quickly dissipated, affecting the use of the transformer.
