What factors are related to the life of thermal paste

Thermal paste is a heat transfer chemical that acts as a heat transfer agent between the semiconductor block and the heat sink. It is an environmentally safe silicone based heat transfer product designed to solve overheating and reliability problems. Its main application is in the field of processing and manufacturing, but it is also widely used in household appliances, automobiles and industrial appliances. It is a pastelike thermal conductive product, which is used to fill between electronic components and heat sinks. It can fully wet the contact surface, thus forming a very low thermal resistance interface, and the heat dissipation efficiency is much superior to other thermal conductive products. While it has such performance, the life of thermal paste will also be affected by some factors. The details are as follows:

1, quality: good quality products can play a long-term good thermal conductivity effect, poor quality not only no thermal conductivity guarantee, but also increase the use of safety risks.

2, Construction: the thermal conductivity of thermal paste is directly related to the construction method, and the thermal paste should be as thin and uniform as possible during construction.

3, radiator material: the thermal conductivity of each material has a certain difference, this difference is called thermal conductivity, the higher the thermal conductivity of the material, the better the thermal conductivity. Currently, LED lights are made of extruded and die-cast aluminum.

4, heat transfer path: any radiator, in addition to the rapid conduction of heat from the heat source to the surface of the radiator, mainly by convection and radiation.

5, heat dissipation area: heat dissipation performance and heat dissipation area also have a great relationship, the greater the heat dissipation area, the more conducive to heat dissipation.

6, surrounding environment: if the performance of LED lamp will be affected by the ambient temperature, if the node temperature is too high, it will lead to the performance of LED decline, so the heat dissipation design is very important.
