Finned heatsink is one of the most widely used heat exchanger equipment in gas and liquid heat exchanger. It is used to enhance heat transfer by adding fins on ordinary base tubes. The base pipe can be steel pipe; Stainless steel tube; Copper tube, etc. The fins can also be used with steel belt; Stainless steel belt, copper belt, aluminum belt and so on.
All heat and cold exchangers with fins on the heat exchange tube to increase the heat dissipation area can be summarized as "finned tube heatsink".
Stamping process is the most widely used finning process at present. It only needs to change the mold to prepare a variety of angles of the fin, has the advantages of flexibility, high efficiency, in the manufacturing of a formed integral fin plate has obvious advantages. The stamping process can produce a variety of continuous or discontinuous fin structures including straight through, sawtooth, arc or triangle.
The stamping process is still developing rapidly, such as the finned plate stamping manufacturing process with holes or turbulence structure, or the multi-pass stamping deep drawing process.
The stamp-fin heatsink solution provides better performance than a typical extruded heatsink because the fin profile is thinner, resulting in greater surface area and lower pressure drop.
The stamping fins and the folded fin heatsink are made of rolled aluminum sheets. Copper forms tightly packed fins. The stamping process uses a progressive tool to cut features and then interlock the fins together. The snap fin heatsink is usually integrated with the heat pipe at the end of the condenser. They are used to cool heat pipes, thereby enabling phase transitions.
The shape of the stamping heat fin is almost square. Because the fin is flat above and below, the contact surface is suitable for welding sealing. Excellent heat transfer capability between adjacent fins is achieved. This advantage ensures the manufacture of compact heat exchangers with excellent heat dissipation.
