The heat dissipation key to wireless charger - thermal graphite sheet

In today's rapidly changing science and technology, wireless charging technology has gradually integrated into our lives with its convenience. However, the problem of heat generated during wireless charging cannot be ignored, which not only affects the charging efficiency, but also may cause damage to the device. In order to solve this problem, the thermal conductive graphite sheet has become a key role in the heat dissipation of the wireless charger.

The conversion rate of wireless charging is lower than that of wired charging, and a large amount of electric energy will be converted into heat and released. The wireless charger is usually small in size, and the heat dissipation challenge of the internal electronic components is more severe. Among them, the charging coil part is the heat concentration area.

In order to effectively dissipate these heat, wireless chargers generally use a variety of thermal conductivity structures and measures. The conductive graphite sheet is an important part of it, and is usually attached to the charging coil. It has the unique performance advantage of being able to quickly conduct the heat generated by the coil.

Thermal conductive graphite sheet is made of graphite material, graphite has good thermal conductivity. Its lamellar structure can conduct heat evenly in both directions and can be well adapted to a variety of surfaces. Compared with traditional metal materials, graphite sheets have lower thermal resistance and higher thermal conductivity.

However, the conductive graphite sheet can only solve the heat dissipation problem on one side of the coil. In order to further transfer heat to the shell, materials such as silicone thermal pads are also needed. Through the silicon thermal pad, heat can be transferred from the graphite sheet to the outer shell, thereby dissipating to the external environment.

In addition, some wireless chargers will also use organic uniform heat film. This film can be placed between the base and the coil, while ensuring heat dissipation, but also has wave transmission performance, will not interfere with the signal.

In addition to the coil, the motherboard is also an important source of heat. There are many electronic components concentrated on the motherboard, which will generate a lot of heat when working. At this time, it is also necessary to use thermal conductive gap filling materials, such as soft thermal silicone pads or thermal grease, to conduct heat to the shell.

These thermal conductive materials have certain softness, excellent insulation and compressibility, and the natural viscosity of the surface can fill the gap, complete the heat transfer between the heating part and the cooling part, and also play the role of insulation, shock absorption, sealing, etc., to meet the design requirements of equipment miniaturization.

In short, the thermal conductive graphite sheet plays a crucial role in the heat dissipation system of the wireless charger. It works with other thermal conductivity materials to effectively solve the heat dissipation problem inside the wireless charger, improve the charging efficiency and the stability of the device, and bring us a more convenient and efficient wireless charging experience.
