Background

The LED display screen component uses a large number of integrated circuits. It is well known that high temperatures are a rival of integrated circuits. The high temperature can not only cause the unstable operation of the system and shorten the service life, but also possibly burn some parts. The heat that causes the high temperature does not come from outside the LED display but inside the LED display or inside the integrated circuit. The radiator is used for absorbing the heat and then radiating the heat into the case or out of the case, so that the normal temperature of the LED display screen component is ensured. Most heat sinks absorb heat by contacting with the surfaces of the heat generating components, and then transfer the heat to a remote place through various methods, such as air in a case, and then the case transfers the hot air to the outside of the case, so as to complete the heat dissipation of the LED display screen. The types of radiators are very many, and CPUs, display cards, mainboard chip sets, hard disks, cases, power supplies and even optical drives and memories all need radiators, and the different radiators cannot be used in a mixed manner, wherein the radiator of the CPU is the most frequently contacted. Depending on the way heat is taken away from the heat sink, the heat sink can be divided into active and passive heat dissipation.
