High temperatures can affect many things. Humans are prone to heat stroke and shock in high temperatures, and electronic equipment or machinery is prone to die or even spontaneous combustion in high temperatures.Heat is generated when electricity passes through electrical components, and the transfer of heat in the air is impeded by the fact that the space inside the equipment is relatively small and full of air, so heat does not flow easily.
The contact between the radiator and the heat source directs heat from the surface of the heat source into the radiator, thus improving the overall equipment temperature, but the interface between the two mutual contacts is not actually complete, there are still many uncontacted interfaces, which are filled with air and the heat passing through the interface is subject to its additional resistance, thus reducing the rate of heat passing through.Before the installation of the radiator will be added to the surface of the heat source thermal conductive material, in order to achieve a lower contact thermal resistance, to improve the rate of heat transfer between the interface, which is the main role of thermal conductive material, and thermal conductive material is not only the ability to have thermal conductivity, depending on the type, you can add some equipment required to operate the function. For example, in the use of the process will produce ultra-high voltage, ordinary thermal conductive materials will easily break through and lose part of the thermal conductivity, so will use high breakdown voltage resistant thermal insulation sheet.
Mass production of products, manual operation of the thermal conductive material would appear to be unable to keep up with the efficiency, so the thermal conductive gel can be applied automatically by machine, thus improving the overall efficiency; some high-tech products need to work in a high precision environment, but their heat sources will produce electromagnetic radiation when in use, affecting their accuracy, so they need to use a thermal conductive absorbent material that can shield electromagnetic radiation and has a thermal conductivity function. There are many more examples of these, so the choice needs to be made according to the customer's use.
