Cooling mechanism of cooling stock bin

The utility model provides a cooling mechanism of a cooling stock bin, which relates to the technical field of cooling mechanisms, and comprises a support assembly and a cooling component, an inserted shell assembly is arranged above the support assembly, and the cooling component is arranged on the shell assembly. The cooling component comprises a pump body, a motor, a first pipe, a condensation pipe, a fin set, a second pipe, a condensate box, a liquid outlet pipe and a side pipe. The pump body is arranged on the top side of the shell assembly. According to the utility model, a plurality of groups of annular sheet-shaped fin groups are combined and attached to the outer side of the condensation pipe, so that the contact area of the cooling assembly and the air is increased, the equipment can realize a relatively large cooling effect with relatively low power when the condensate works, the power of the equipment is effectively saved, and the working efficiency of the equipment is improved. And the power wast
