![]() There are three types of heat sinks: passive, active, and hybrid. This is done in four basic steps: the source generating heat, transferring heat away from the source, heat distributing through the heat sink, and heat moving away from the heat sink. ![]() ![]() A heat sinks moves heat away from a critical component. The total surface area of the heat sink becomes beneficial, as a large surface area provides an increased area for thermal diffusion and convection to occur.This relies on a temperature gradient, so no convection and subsequent heat removal will occur if the surrounding temperature is not cooler than the heat sink.The working fluid passes across the surface of the warm heat sink, using thermal diffusion and convection to move heat away from the surface and into the surrounding environment.Heat moves away from the heat sink: This process relies on the heat sink's temperature gradient and its working fluid-most commonly air or a non-electrically-conductive liquid. ![]() This means that heat sinks will usually be hotter towards the source and cooler towards the sink's extremities. Heat distributes throughout the heat sinks: Heat naturally travels throughout the heat sink via natural conduction, moving across the thermal gradient from a high-temperature to a low-temperature environment.Heat transfers away from the source: Heat moves into the heat sink and away from the source via natural conduction, which is directly impacted by the heat sink material's thermal conductivity. This is made possible due to high-thermal conductivity materials such as copper and aluminum in the heat sink.The source generates heat: This source is any system that creates heat and requires it to be removed to function.How does a heat sink work?Ī heat sink moves heat away from a component in four basic steps: Heat sinks use a thermal conductor to move the heat into fins, which have larger surface areas and thus disperse heat throughout the computer. The dissipation of heat is possible because a heat sink has fins, which give more surface area during a heat transfer.Ī heat sink needs to make strong contact with the source of heat in order to maximize cooling. It is designed to absorb the heat coming from your CPU and then disperse the heat away from its components. Having a heat sink is critical because it helps your CPU cool even if you use it for a long period of time. If they receive too much heat, they become damaged and, therefore, useless, posing a risk to the functionality of high-performance computers. ![]() Without the heatsink, the heat generated by the components stay in your CPU, which will burn or fry it.īecause most components are made of electronic chips, they absorb heat easily. What is the purpose of a heat sink?Ī CPU is prone to overheating because some of its components product heat. In most cases, however, the heatsink is combined with a fan that blows the hot air away or a liquid cooling solution that carries the heat halfway through the pipes. What is a heat sink?Ī heat sink is a piece of metal that sits on top of a computer chip such as a CPU and draws power away from components by letting it rise through a series of fins.īy themselves, heat sinks are passive, meaning they have no moving parts. In this blog, you'll learn how heat sinks help protect your computer's CPU from overheating, ensuring maximum efficiency and the protection of critical parts and components. A computer's CPU (central processing unit) is often prone to overheating because some of its components overheat, posing risks to the entire computer's functionality. ![]()
