Heat sinks are important products needed for electronic devices to cool down to help prevent the overheating of a device. If you are searching for a company that can provide you with high-quality heat sinks, this article is for you. In this article, we will be discussing everything you need to know about heat sinks.
What is a Heat Sink?
A heat sink is a device that allows passive heat exchange which transfers heat from an electronic or mechanical device to a coolant where it dissipates the heat away from the device. A heat sink allows the device to have optimal temperature levels, therefore preventing it from overheating.
This is a device that draws heat from an electronic device such as smartphones, computers, DVD players, laptops, and even in some refrigerators. Electronic devices like computers must have a quality heat sink to prevent it from overheating. A computer’s processor can be at risk of overheating, which means it can destroy the entire system, costing you lots of money when it happens, so if you want to prevent your system to overheat, you must choose a high-quality heat sink.
Heat sinks have thermal conductor properties that help dissipate heat away from the device, therefore cooling the heat sink and the device. Heat sinks need airflow to work properly, so it usually has fans built-in with it.
These should also have a large surface area that allows heat to dissipate faster and keep the whole device cool and avoid overheating.
A heat sink is a passive heat exchanger that transfers or removes heat from a device. The heat sink is a metallic part, usually made from aluminum alloy. It is usually attached to the device which allows heat to be absorbed and dissipated to the surrounding fluid or a cooling system that prevents the device from overheating.
The device like a computer’s CPU will transfer the heat to the heat sink by using the process of conduction. Heat transfer from the heat sink uses convection, and radiation has a small role as well in the overall system.
There are two types of heat sinks: Active and Passive Heat Sink.
Active heat sinks make use of the power supply of the device and it may also include a fan or blower. It provides excellent performance and this consists of several moving mechanical parts. This type is usually considered more expensive than passive heat sink types.
Passive heat sinks do not have any mechanical components, even so, they are still reliable and can be used to disperse heat from the device and prevent it from overheating. Passive heat sinks are made from an aluminum-finned radiator and it removes thermal energy by using the process of convection. They do not have any moving parts, so they are considered more reliable. For passive heat sinks to work their best, they need to have continuous airflow moving across its fins.
Heat sinks can be made from a variety of materials. Two of the most common materials used are copper or aluminum.
- Aluminum Heat Sinks – The most common material used for the heat sink production is aluminum. Aluminum heat sinks are used for different projects since it is lightweight and provides good thermal conductivity.
- Copper Heat Sinks – Copper offers better thermal conductivity than other materials, but it is heavier and costs more than aluminum.
What are the advantages of using an aluminum heat sink?
Aluminum alloy has high-thermal conductivity properties which makes it a good choice for heat sink products. It is energy-saving, low-cost, low-weight, has a great appearance, etc. An aluminum alloy is the best device for thermal energy conversion. It heats fast and is considered as very efficient.
An aluminum heat sink is considered the lightest when compared to other varieties of heat sinks. It is easy to use and handle, therefore, easy to install. It conducts heat, dissipates heat well, and it is a high-strength metal.
A heat sink made from aluminum conducts heat better and it can withstand pressure and has high thermal strength. It has a good appearance, which improves the appearance of the heat sink. It is also eco-friendly and energy-saving does not use any materials that can affect the environment.
Aluminum heat sinks don’t weigh a lot, these weigh about a tenth of cast iron heat sinks, but its cooling strength is four times than that of cast iron.
In terms of the manufacturing and production process, an aluminum heat sink is preferable. It is the best material to use and choose. It offers a lot of advantages; it is low-cost, which makes you save a lot of money in the process. The aluminum heat sink has good color and decoration that adds value to its appearance.
