Heatpipe Through Fin Process

     Heatpipe through fin technology is a technology for connecting the heat pipe and the radiator. Through fin, the heat pipe is inserted between the fins, and the fins wrap the heat pipe. In this way, the contact area between the fins and the heat pipe is increased, and the conduction efficiency is much higher. Although through fin process, the contact area between the fins and the heat pipe is increased, and the heat conduction efficiency is effectively improved, it is inevitable, The gap between the fin and the copper tube can not be completely eliminated.

   Since the gap can not be eliminated, there are still some defects in the heatpipe through fin process. However, because this process is simple and low cost, it has become the manufacturing process adopted by most manufacturers. In addition, the welding process on the market can not ensure that no gap is left, but the heatpipe through fin process can achieve more than 90% seamless, and the overall effect is commendable. Although the heatpipe through fin process increases the contact area between the fin and the heat pipe and effectively improves the heat conduction efficiency, it is inevitable that, The gap between the fin and the copper tube can not be completely eliminated.

     Although the gap can not be eliminated, this process is widely used in the production of various radiators because of its simple manufacture and low cost. In general, we believe that the welding process has the lowest thermal resistance and is firmly fixed, and the fins are not easy to loose and deform; The fin piercing process has low cost and simple fabrication. Theoretically, the thermal resistance of the contact surface is a little higher than that of welding, but the performance of excellent fin piercing process is almost the same as that of welding process.
