The cooling unit 1 further comprises a cooling tank 7, and the evaporator 6 extends into the cooling tank 7 so as to cool the electroplating liquid medicine in the cooling tank 7 to the freezing critical point.

The cooling box 7 is substantially a box body and has an inner cavity 8, a liquid inlet pipe 9 and a liquid outlet pipe 10, wherein the liquid inlet pipe 9 and the liquid outlet pipe 10 are respectively communicated with the inner cavity 8. The liquid inlet pipe 9 is provided with a liquid inlet pump 23 for pumping the electroplating liquid medicine recycled from the workshop into the inner cavity 8.

The cooling unit 1 further comprises a four-way valve 14, the four-way valve 14 being arranged in a cooling circuit formed by the refrigerant compressor 4, the condenser 5 and the evaporator 6 to switch the flow direction of the cooling medium (freon) between the condenser 5 and the evaporator 6, thereby enabling the evaporator 6 to heat the interior space 8 for defrosting.

The stirring assembly 2 comprises a motor I11 and a stirring end 12, wherein the stirring end 12 can be at least one of a rotating blade (in the example), a rotating spiral and a vibrating blade.

The stirring end 12 is arranged in the inner cavity 8, so that the electroplating liquid in the inner cavity 8 is stirred, on one hand, ice accumulation in a large area can be prevented, and on the other hand, the treatment efficiency can be improved.

The bottom of the cooling box 7 is provided with a circle of guide plates 36, and the circle of guide plates 36 are approximately funnel-shaped so as to be beneficial to guiding out the electroplating liquid medicine.

A liquid level sensor I28 is arranged in the cooling box 7 and used for detecting the liquid level height.
