Efficient heat dissipation #-shaped high-power resistor

The invention discloses an efficient heat dissipation #-shaped high-power resistor which comprises a bottom plate, a first pin, a second pin, an upper cover plate, a temperature sensor, a controller,a resistance wire, a heat dissipation hole, a dust screen and a fan, two connecting rib plates are arranged at the top end of the bottom plate, and the connecting rib plates are symmetrically distributed at the top end of the bottom plate; the ends, away from the bottom plate, of the two connecting rib plates are fixedly connected with an upper cover plate, the controller is fixedly installed on one side of the top end of the bottom plate, and the draught fan is fixedly installed at the end, away from the controller, of the bottom plate. The resistance wire is fixed in the resistor through thefixing buckle, the resistance wire is spirally installed in the resistor, the cross sectional area and the effective length of the resistance wire are increased, the working efficiency of the resistor is improved, the interio
