The utility model discloses an
overcharge liquid cooling device in the technical field of
overcharge, which comprises a protective shell, a cooling tank is arranged on the inner wall of the protective shell, the cooling tank is arranged towards one end in a penetrating manner, the inner wall of the cooling tank is fixedly connected with a liquid cooling
assembly, and the inner wall of one end, far away from the liquid cooling
assembly, of the cooling tank is fixedly connected with a circulating
pipe. The bottom of the end, close to the circulating
pipe, of the cooling tank is fixedly connected with a temperature sensor. The protective shell is fixed to the outer wall of the
overcharge working equipment through the outer wall fixing equipment, then the
working temperature of the overcharge working equipment is detected through the temperature sensor, the detected temperature is sent to the external
intelligent control equipment, and then the
circulating pump is started to input cooling liquid into the circulating
pipe; the cooling operation is performed on the over-charging equipment through the cooling liquid and the circulating pipe, and meanwhile, the cooling motor is started to drive the cooling fan blades to be matched with the cooling groove to improve the over-charging
cooling effect, so that the working efficiency of the super-charging column is improved.
