Heat dissipation support

The utility model provides a heat dissipation support, which relates to the technical field of heat dissipation supports and comprises a first arc plate, a second arc plate is arranged on one side of the first arc plate, three first connecting plates are fixed on the arc edge of one side of the first arc plate and close to the bottom, and two second connecting plates are fixed on the arc edge of one side of the second arc plate and close to the bottom. The two second connecting plates are located between the first connecting plates, supporting plates are fixed to the bottoms of the first arc plates, and moving plates are fixed to the bottoms of the second arc plates. According to the utility model, through mutual cooperation of components in the heat dissipation assembly, the effect of blowing airflow in the transformer towards the coil can be achieved, so that the effect of improving the heat dissipation efficiency of the coil can be achieved, meanwhile, a rotating handle is rotated to drive a one-way screw
