Description

The present invention relates to an enclosed radiator, in particular to a partition wall structure of an enclosed radiator.

Radiators are widely used in various products. Generally speaking, higher-end products usually use water-cooled radiators, which have the advantages of quietness and stable cooling compared with air-cooled radiators. In addition, the water-cooled radiator forms a closed space by welding the upper and lower workpieces to fill the working fluid.

However, during the soldering process where solder is applied, the melting of the solder often produces residues such as bubbles, slag inclusions, and flux. Moreover, when the welding workpiece is very complicated, a preset welding piece is used to place between the upper and lower workpieces, and pressure is applied to the upper and lower workpieces during the welding process, making it difficult for these impurities to be discharged from the welding plane, and then A large number of voids are formed, resulting in poor soldering, especially for soldered parts with flux applied.
