The main function of the LED heat sink is how the LED heat sink works.

LED cooler, as its name suggests, is a product that cools LED products. Its function is to prevent LED products from being damaged due to high temperature during use. Therefore, LED coolers have an indelible effect. Below I will introduce you to the main role of the LED heat sink and what is the working principle of LED heat dissipation.

The main role of LED radiator:

The main function of the LED heat sink is to continuously derive and dissipate the heat generated by the operation of the LED chip to the environment, so that the temperature of the chip is kept within the required range, thereby ensuring that the LED lamp can work normally. The quality of the LED heat sink depends mainly on the thermal resistance of the heat sink. The smaller the thermal resistance, the lower the junction temperature of the LED light under the same conditions, and the lower the junction temperature of the LED, the longer the life of the chip will be. Therefore, the LED lamp radiator must have a certain heat dissipation area, and the material of the heat sink must have a certain thermal conductivity and a high heat radiation coefficient; in addition, the heat conductive material itself should also have light weight, easy processing, and low price. Features.

What is the working principle of the LED heat sink?

The thermal resistance of the LED heat sink should include both thermal resistance and thermal resistance. For a certain shape of LED heat sink, the thermal resistance is mainly related to the thermal conductivity of the heat sink material. The larger the thermal conductivity, the smaller the thermal resistance and the better the thermal conductivity. Under certain environmental conditions, the thermal resistance depends mainly on the LED. The heat dissipation area of the heat sink and the radiation coefficient of the surface material of the heat sink, the larger the heat dissipation area, the higher the radiation coefficient, the smaller the heat dissipation resistance, and the better the heat dissipation effect.

The so-called LED heat sink is a component that can quickly derive and dissipate heat generated in the operation of the LED chip into the environment. Therefore, it is impossible to have only a certain heat dissipation area as a heat sink, and the material for manufacturing the heat sink must have a certain heat conduction. Sex, that is, to have a higher thermal conductivity, the heat generated by the chip can be continuously exported and finally dispersed into the environment; of course, for the thermal conductive material, in addition to thermal conductivity, it should have a small specific gravity, low price, and high strength. Easy to process and other features.
