Comparison between thermal graphite film thermal silicon film?

the society we live in, into the era of electronic products, life has begun to change all aspects. However, electronic products have a feature that the faster the calculation speed, the greater the calorific value. When the heat is high, it will also affect the operation speed of electronic equipment. All electronic manufacturers have been trying their best to solve this problem. Whether it is to install fans for components to apply silicone grease on the surface. , as now, put a layer of thermal conductive silica gel on the surface of electronic components. With the development of technology, thermal conductive graphite sheets are emerging. it's just as popular as thermal silicon wafers. What is the difference between thermal graphite film thermal silicon film? In fact, the difference between them can be generally compared the use scope, material characteristics other aspects.

1. The characteristics of raw materials determine the characteristics of products

The difference between thermal conductive graphite film thermal conductive silicon film lies in that the thermal conductive silicon film is a material based on silica gel. At the same time, in the production process, we need to add auxiliary materials according to a certain proportion. the requirements for auxiliary materials are low. Otherwise, it will achieve the desired cooling effect. Of course, graphite is the main raw material of thermal conductive graphite sheet, which can intercept the heat source. realize multi-directional heat conduction.

2. Different heat dissipation characteristics

The second difference between thermal graphite film thermal silicon film is the difference in heat dissipation. Thermal conductive silicon film is very flexible with auxiliary materials. When it absorbs the heat, it dissipates it through its own gaps. Generally speaking, the more auxiliary materials are added to the thermal conductive silicon film, the more powerful its heat dissipation capability is. it can also play the role of insulation. When conducting heat, the thermal conductivity of the graphite sheet is vertical. Because of its high thermal conductivity, it can actively diffuse the heat source. At the same time, we can try our best to shield all the heat sources protect the electronic components.

3. Different production processes lead to different thickness

The obvious difference between thermal graphite film thermal silicon film is that the thickness of the finished product will matter because of different materials production processes. But it is precisely because of this characteristic. So they need to be used on different devices to cool down. For example, the heat-conducting silica gel sheet is much thicker than the heat-conducting graphite sheet, its shape is much larger. So people often use it in the electronic products with larger volume. Like on a tablet. But because of its thin thickness small volume, the heat-conducting graphite sheet can only be used on those small devices, the most common one is the mobile phone in our life.
