What are the characteristics of a phase change thermal pad?

Electronic products are related products based on electric energy. When electric energy is converted into other energy, it will be lost, and most of it will be dissipated in the form of heat. Therefore, heat generation when electronic products are running is unavoidable.

The heat source of electronic products is mainly the internal power consumption electronic components. The internal space of electronic products is limited and the ventilation is not smooth, so it is difficult to dissipate the heat after it is generated, and it is easy to cause it to accumulate in the equipment, resulting in high temperature. too high. Therefore, it is not feasible to rely on the heat dissipation of electronic products themselves, and it is necessary to use heat dissipation devices.

In addition to heat dissipation devices, thermally conductive materials are also indispensable. Thermally conductive materials are a general term for materials that are coated between the heat source of the equipment and the heat sink device and reduce the contact thermal resistance between the two. The phase change thermal pad is a member of the thermally conductive material. , is also a very characteristic of a new type of thermal conductivity material.

Phase change thermal pad is different from conventional thermal pads and thermally conductive silicone grease. The thermally conductive phase change film will change from solid sheet to semi-flowing paste within the characteristic temperature. When the temperature returns to normal temperature, it will change to solid sheet again. The feature of the sheet is outstanding in its excellent thermal conductivity. When the temperature rises, the thermally conductive phase change sheet will soften, and quickly fill the gaps and holes, greatly reducing the contact thermal resistance, so that heat can be quickly transferred to the heat dissipation device, so the thermal conductivity of the thermally conductive phase change sheet will be better than Thermally conductive silicone sheet.
