Performance optimization for side-pressed fin heat sinks with COOLTEC

Side-pressed aluminum fin heat sinks offer high cooling performance in a compact design. Through targeted performance enhancements – such as the use of heat pipes or copper inserts – COOLTEC sustainably improves heat dissipation. These solutions are specifically tailored to applications with high power density and limited space, preventing overheating and extending the service life of sensitive electronics.

Pressed-in heat pipes

Heat pipes transfer heat extremely efficiently from the heat source to the cooling fins. Their closed circuit allows the internal fluid to evaporate when heated, transport the heat, and condense in cooler areas. This makes them ideal for localized hotspots and high power densities.

Copper inserts as heat spreaders

Copper has a significantly higher thermal conductivity than aluminum. Embedded copper inserts ensure uniform and targeted heat distribution, for example beneath fluid channels or heavily loaded components. This results in stable operating temperatures and extends the lifespan of electronics.

What are side-pressed fin heat sinks?

Side-pressed fin heat sinks are a special type of air-cooled heat sink distinguished by their unique construction. The fin-like plates are pressed in from the sides, creating a particularly stable structure.

This design significantly increases the cooling surface area, optimizing heat dissipation through convection and improving overall cooling performance. The symmetrical design also enables double-sided component mounting and cooling.
