A universal circuit breaker temperature detection and heat dissipation mechanism comprises a shell and a circuit breaker body arranged in the shell, the heat dissipation mechanism is divided into an air outlet assembly and at least one air inlet assembly, the air inlet assembly comprises an air inlet pipe arranged on the shell, and an air inlet is formed in the circuit breaker body. The air inlet assembly comprises an air inlet arranged on the circuit breaker body, an air inlet fan for blowing airflow to the inside of the circuit breaker body is arranged at the air inlet, the air outlet assembly comprises an air outlet arranged on the circuit breaker body, an air outlet fan for blowing airflow to the outside of the circuit breaker body is arranged at the air outlet, and at least one air inlet and the air outlet form an airflow loop. A noise reduction mechanism used for absorbing sound of airflow blown by the fan is arranged in the shell. The air-cooled heat dissipation air is effectively filtered, the service
