What Is a Heat Sink?

A heat sink is a device that transfers heat from a target object or medium to the surrounding environment through heat exchange, thereby lowering the target temperature and ensuring its stable operation. Its core function is to resolve heat accumulation issues generated during an object's operation, preventing performance degradation, malfunctions, or even damage caused by excessive temperatures.

What is the core issue being addressed?

Extruded heat sink components are primarily made of aluminum alloys (such as 6063 aluminum) or copper. Aluminum has a thermal conductivity of approximately 200 W/m·K, while copper exhibits a significantly higher value of 390 W/m·K,enabling rapid heat transfer to the radiator surface. The intricate fin structure design increases the heat dissipation surface area, allowing heat to be efficiently conducted and dispersed across the entire radiator surface. This prevents localized overheating and ensures stable equipment operation.

How Does a Heat Sink Work?

The core operating principle of a heat sink involves the synergistic interaction of three heat transfer mechanisms— thermal conduction, thermal convection, and thermal radiation—to efficiently dissipate heat from a heat-generating component into the surrounding environment, thereby achieving cooling.
