The invention provides a liquid cooling control circuit and charging equipment, and the circuit comprises a temperature screening module and a liquid cooling control module. The temperature screening module is electrically connected with the liquid cooling control module; the temperature screening module is configured to convert the temperatures of the cooling liquid collected at multiple positions into voltages, screen the highest voltage as a control voltage and send the control voltage to the liquid cooling control module; and the liquid cooling control module is configured to start the liquid cooling system when the control voltage is greater than the preset voltage, and close the liquid cooling system when the control voltage is smaller than the preset voltage. A pure hardware circuit is adopted and is controlled separately from the liquid cooling system, the heat dissipation effect of the liquid cooling system is guaranteed, and the reliability and stability of the liquid cooling control process are effectively improved. And aiming at different liquid cooling systems, only the switch needs to be switched on and off according to the on-off signal, a software control strategy does not need to be additionally developed, the development workload is greatly reduced, and the applicability is wide.
