Description

Automobile accessory cooling device

Technical Field

The invention relates to a cooling device, in particular to an automobile accessory cooling device.

Background

When the automobile parts are just machined, the temperature is often very high, the parts can deform to a certain extent due to overhigh temperature, and if the automobile parts are not cooled, the precision of the parts can be influenced in subsequent machining, so that the reject ratio of products is increased, and the cooling treatment is needed. The cooling treatment mode is generally divided into water cooling and cold air cooling, and the accessory is usually placed on a bearing object during cooling, and then the surface of the accessory is cooled by using a cooling device. However, in the traditional cooling mode, the accessories to be cooled are usually placed on the bearing object to be cooled, the contact surface of the accessories and the bearing object cannot be changed, so that the contact surface of the accessories and the bearing object cannot be cooled, the cooling effect is poor, the accessories cannot be uniformly cooled, the cooling efficiency of the accessories is reduced, and the forming time of the product is further reduced.
