Stacked heat sink manufacturing

The stacked radiating fins formed by this tight fitting method can realize the upper and lower double bottom plate heat dissipation structure. Heat dissipation power devices can be installed on both sides.

High-power stacked heat sink
Stacked fins are designed into a special structure of single fins, multiple fins, and single-profile heat dissipation fins that are superimposed layer by layer using an ultra-high pressure extrusion method to form a heat dissipation body. The stacked radiating fins formed by this tight fitting method can realize the upper and lower double bottom plate heat dissipation structure. Heat dissipation power devices can be installed on both sides. This process does not use any medium to realize the combination, has the characteristics of low development cost, free combination of heat sinks of different widths and structures, and strong versatility. Widely use the heat dissipation of high-power equipment such as power inverter transformers and engines.

Stacked heat sinks have the following advantages: increase the heat dissipation area while forming a closed heat dissipation channel. Therefore, it has better heat dissipation performance, unlimited increase in volume, high strength, low production cost, convenient installation and maintenance, and long service life. Through technological innovation, KangDing Thermal has mastered the processing technology of restacking aluminum extruded heat sinks to produce high-power stacked heat sinks. Our company has many mature stacked radiator production lines, which produce multiple batches of large-scale stacked radiator fins for Israeli military enterprises and have been recognized.

Processing process of stacked heat sink:
Single fin for profile heat sink
According to the engineer’s design drawings, cut the aluminum profile into a single fin for the heat sink

Ultra-high pressure extrusion stacked fins
Then the single fins of the radiator are spliced together by a stamping process
 
Finished stacked heat sink
After splicing into semi-finished products, surface treatment and polishing are performed. The product can also be processed by tapping, drilling, and milling grooves. It is a complete stacked heat sink.
