Heat dissipation device of solid-state circuit breaker

A solid-state circuit breaker heat dissipation device comprises a control unit, a temperature sensor, a refrigeration module and a heat dissipation module, the temperature sensor transmits a sensed temperature signal to the control unit, and the control unit can drive the refrigeration module to work according to the temperature signal. The refrigeration module is driven by the control unit to generate a cooling surface in contact with the heat dissipation surface of the semiconductor switch module and a heat dissipation surface in contact with the heat dissipation module, and the refrigeration module transmits heat of the semiconductor switch module to the heat dissipation module and dissipates heat to the surrounding environment; the control unit obtains the temperature Ta of the surrounding environment of the heat dissipation device of the solid-state circuit breaker, the temperature Tc of the heat dissipation surface and the temperature Te of the heat dissipation module through the temperature sensor, and
