Stacked Fin Heat Sink

Stacked Fin heat sink is formed by super-high pressure extrusion of single tooth fins, multi tooth fins and single profile fins with special structure. The stacked heat sink formed by this tight fitting method can realize the upper and lower double bottom plate heat dissipation structure, and power devices can be installed on both sides. 

This process does not use any medium to realize the combination. It has the characteristics of low development cost, and can freely combine heatsinks of different widths and structures. It has strong versatility. It is widely used for heat dissipation of high-power equipment such as power frequency converter transformers and engines.

Cut the aluminum profile into a single heat sink according to the design drawings

Splice the heat sink single pieces with stamping process

After being spliced into semi-finished products, surface treatment, such as fly-cuts, can also be carried out by tapping, drilling, milling and other processes, which is a complete stacked fin heat sink.

Stacked fin heat sink has the following advantages: 

1. Increase the heat dissipation area and form a closed channel, so it has good heat dissipation performance

2. Unlimited volume

3. High strength

4. Low production cost

5. Convenient installation and maintenance

6. Long service life.
