- Product Introduction
Product Specification
There are several types of heatsinks available in the market, and each of them possesses unique features and functions. Here are some of the commonly used types of heatsinks with their respective features below:
Passive Heatsink
Passive heatsinks operate without a fan and use only convection to dissipate heat. They are less noisy and require less power consumption. However, they cannot cool down high power devices.
Active Heatsink
Active heatsinks use a fan or blower to blow air across the heatsink and increase heat dissipation. They can cool down high power devices efficiently but are more noisy and consume more power.
Extruded Heatsink
Extruded heatsinks are made from aluminum or copper and consist of an extruded aluminum body with fins to increase the surface area and heat dissipation. They are relatively inexpensive, lightweight, and easy to manufacture.
Bonded Fin Heatsink
Bonded fin heatsinks use stacked layers of thin aluminum sheets with fins bonded to them to increase the heat dissipation area. They are more expensive than extruded heatsinks but offer higher efficiency.
Skived Heatsink
Skived heatsinks are made by skiving or cutting thin sheets of metal to create fins on the surface. They provide higher surface area per unit volume, making them more efficient in dissipating heat.
Heatpipe Heatsink
Heatpipe heatsinks use heatpipes to transfer heat from the heat source to the heat dissipating fins. They offer higher efficiency and can cool down heat sources with high thermal loads.
Pin Fin Heatsink
Pin fin heatsinks consist of a matrix of small pins or needles that increase the surface area for heat dissipation. They are efficient, lightweight, and are widely used in electronic devices.
Fanless Heatsinks
Fanless heatsinks use natural convection or a heat pipe-based system to dissipate heat without any fans. They are noiseless and require less maintenance, making them ideal for devices that need to be used in noise-sensitive environments.
