Computer Heat Sinks may be familiar to many computer enthusiasts or owners. Our desktop computer makes a sound as soon as it works inside the main unit, which is the heat sink. Laptops also have built-in Heat Sinks. Usually to lower CPU temperature, works fine. We need to buy an external radiator when we play games for a long time, so how exactly does a radiator work?
How Computer Heat Sinks Work - Why You Need a Heat Sink
Integrated circuits are used extensively in computer components. High temperatures are the enemy of integrated circuits. High temperatures can destabilize the system, shorten its life, and possibly burn out some components. The heat that generates the high temperature is not outside the computer, but inside the computer or inside the integrated circuit. The role of the heat sink is to absorb this heat and then disperse it inside or outside the case to confirm that the temperature of the computer parts is normal. Most heatsinks are in contact with the surface of the heat-generating components, absorb the heat, and transfer the heat far away by various methods (such as the air inside the case), and the case transfers this hot air to the outside of the case, thereby completing the computer heat. There are many types of heatsinks, and CPUs, graphics cards, motherboard chipsets, hard drives, chassis, power supplies, optical drives, and memory also require heatsinks. These different heatsinks cannot be mixed, and the one that touches the most is the CPU heatsink. Depending on the way the heat sink dissipates heat, the heat sink can be divided into active and passive cooling. The former is common in air-cooled radiators, and the latter is common in radiators. If the cooling method is further subdivided, it can be divided into air cooling, heat pipe, water cooling, semiconductor cooling, compressor cooling, etc. The working principle of the radiator - an introduction to the cooling method of the radiator
Heat generation is the main method of radiator heat dissipation. In thermodynamics, heat dissipation is heat transfer, and there are three main methods of heat transfer: heat transfer, heat convection, and heat radiation. The transfer of energy when the substance itself or the substance is in contact with the substance is called heat conduction, which is the most common way of heat conduction. For example, the CPU heat sink base is thermally conductive in a way that it is in direct contact with the CPU to remove heat. The tropical flow refers to the heat transfer method in which the flowing fluid (gas or liquid) moves the tropical zone. Common in the thermal system of the computer case is the "forced thermal convection" thermal method in which the hot fan guides the gas flow. Thermal radiation means relying on light radiation to transfer heat, the most common of which is solar radiation every day. None of these three cooling methods is isolated, and in daily heat transfer, all three cooling methods occur simultaneously and work together.
Heat sinks are widely used on small computers. In order to dissipate heat, large instruments do not work for a long time, burn parts, and use radiators to quickly disperse the heat of MOIN to ensure the normal operation of the machine and prolong its life. In a word, radiators have been widely used in our lives.
