Appearance patent of mechanical foundation

Passing through the fin means that the heat pipe passes through the fin directly by mechanical means. This process has low cost and simple process, but it has high technical requirements for the process itself. Otherwise, it is easy to make the contact between the heat pipe and the fin not close, resulting in high interfacial thermal resistance. The cross-sectional thermal resistance of heat pipe and fin is almost equal to that of welding, but the cost can be greatly reduced. In fact, fin piercing technology is a patented technology of AVC, which makes AVC radiator not only have strong heat dissipation performance, but also maintain a relatively low price.

As I said just now, there is basically no difference in performance between welding and fin piercing. However, in terms of cost, welding each heat pipe will be about 1 USD higher than passing through fins, so the price of heat pipe radiator with welding process is generally higher. Users should determine the purchase direction according to their own spending power.

The heat pipe has the best heat transfer efficiency in the straight-through state. But in fact, heat pipes are often bent. After bending, the heat transfer performance will decrease in different degrees, which is also closely related to the process quality.

Welding is to weld the fin and heat pipe together, which is characterized by solder residue and holes left by welding on the fin.
