The Specification of Extrusion aluminum heat sink

April 03, 2023

Extrusion aluminum heat sinks are used to dissipate heat from electronic components to the surrounding environment. The specification of extrusion aluminum heat sink includes the following:

1. Material: Extrusion aluminum heat sinks are made of high-quality aluminum alloy. The most commonly used aluminum alloys are 6061 and 6063.

2. Dimensions: The dimensions of the heat sink depend on the application and the size of the electronic component it is intended to cool. The length, width, and height of the heat sink are important factors to consider.

3. Fin density: The number of fins per inch on the heat sink determines its cooling capacity. The higher the fin density, the better the heat dissipation.

4. Fin thickness: The thickness of the fins affects the overall weight of the heat sink. Thicker fins provide better cooling but add to the weight of the heat sink.

5. Base thickness: The thickness of the base of the heat sink affects its rigidity and ability to transfer heat from the electronic component to the fins.

6. Surface treatment: The surface of the heat sink can be treated with anodizing, powder coating, or other methods to improve its durability and corrosion resistance.

7. Mounting method: The heat sink can be mounted using clips, screws, or thermal adhesive. The mounting method should be chosen based on the application and the weight of the heat sink.

8. Thermal performance: The thermal performance of the heat sink is measured in terms of its thermal resistance and thermal conductivity. The lower the thermal resistance and the higher the thermal conductivity, the better the heat dissipation.
