The utility model relates to electrical power conversion, belongs to the field of electrical safety, and particularly relates to a transformer with double heat dissipation modes. Comprising a transformer, an upper cold plate (5), two pressing plates (6), four supporting columns (7), two magnetic core supports (8) and a lower cold plate (9). The transformer is in a liquid cooling heat dissipation mode, and when liquid cooling heat dissipation fails, power output with the half load or above can be provided through air cooling heat dissipation. According to the heat dissipation scheme, a double-cold-plate mode is adopted, and the transformer is clamped between the upper cold plate and the lower cold plate. The liquid cooling flow channels are arranged in the double cold plates, a multi-flow-channel parallel connection mode is formed in the winding due to the design of the reinforcing ribs, the turbulent flow columns are densely distributed on the portions, making contact with the transformer winding, of the wind
