New Energy Automotive Aluminum Extrusion Heatsink

Extruded aluminum is one of the most popular and cost-efficient heatsink manufacturing methods. The aluminum extrusion heatsink for new energy automotive is used widely because of its high strength, good water tightness and air tightness, good thermal conductivity, beautiful appearance, and easy processing. In addition, extruded aluminum heatsinks provide greater structural stability. The aluminum extrusion heatsink is also very flexible in the kind of surface treatment, as aluminum can be anodized to different colors.

Because aluminum has excellent thermal conductivity, it is lightweight and energy efficient. Copper heat sinks are not widely used due to the high price of copper and the fact that it is not easy to machine into beautiful shapes. The heat dissipation and corrosion resistance of stainless steel are not as good as that of aluminum. Therefore, the best choice for the heatsink material is aluminum.

Extruded aluminum heatsinks are made by first heating aluminum until it is soft, then pushing the softened metal into a machined die that shapes the heatsink's contours. Once the length of the heatsink is reached, the extruded heatsink is cut from the die, then cooled and ready for use. This process creates a solid structure that can be bonded directly to the heat source.

1. Aluminum profile has good thermal conductivity, so the aluminum extrusion heatsink is widely used in many industries.

2. Corrosion resistance and long service life. A thick oxide film will form on the surface of the aluminum alloy material.

3. The aluminum extrusion heatsink can be treated with various surface treatments, with various designs and colors, no solder joints, strong decoration, beautiful and durable.
