The welding radiator is a heat-dissipating product produced by the welding process as the main process.
This type of soldering heat sink is technically combined by soldering the bottom plate and fins of the heat sink. The soldering process is very versatile and can be soldered as long as the surface is solderable and can withstand a certain temperature.
The most commonly used materials for soldering fins are copper and aluminum. Copper and aluminum are the most widely used in terms of cost, structure, performance, heat transfer and cost.
