Problems solved by technology

However, although this method has no harm to the human body and the environment from the above-mentioned chemical substances, the plastic melting caused by the friction of different metals still has the problem of the uniformity of the plastic melting part, and it is easy to form gaps that affect the bonding and heat transfer efficiency.

[0008] In addition, in other practical manufacturing methods for heat pipes and heat dissipation fins, the industry adopts the method of piercing and pressing, mainly using stamping fixtures and automatic tools, and the through holes on the end faces of the heat dissipation fins correspond to the heat dissipation process piece by piece during the pressing process. The outer diameter of the conduit produces a tight bond; however, the above press-pressing production method, in addition to the time-consuming production of one-by-one pressing, what's more, each cooling fin is subjected to punching vibration of the machine and the through-hole production during the pressing process. Tolerance will affect the alignment and tightening effect of heat dissipation fins and heat pipes, and it is easy to produce unbonded gaps in different positions, resulting in high defective rate, poor heat transfer efficiency and heat dissipation effect, etc.

[0009] As for the current industry, another method of combining stamping automatic equipment and stamping fixtures is to put heat pipes through multiple pitches and combine them with heat dissipation fins. The sharp plate-shaped molded parts cooperate with the stamping process of the stamping tool. The long tapered end of the molded part exerts force to cause the heat pipe to deform in a long area and tighten the heat dissipation fins. However, the heat pipe and the heat dissipation fins are tightly connected. The tight connection and thermal conduction of the fins are only sufficient on the joint surfaces of the fins. However, the above-mentioned conventional manufacturing method, which is stamped by the end of the elongated tapered tip, will make the heat pipe produce a long and large heat pipe. The deformation of the area leads to the reduction of the inner diameter of the entire heat pipe, the decrease of the fluid flow rate and the increase of the flow resistance, which reduces the heat conduction efficiency, and generally cannot achieve good uniformity due to the applied force, so that only the joint surface still has gaps and fails to achieve Good bonding and heat transfer, and if a large stamping force is applied without good bonding, it may cause the heat pipe to break, and the defect rate is high
