In electronic product design, "hotspot" refers to the phenomenon where the local temperature on the surface of a chip or component is much higher than the surrounding area. These hotspots are not only "killers" of performance, but also "invisible disruptors" of reliability. Due to its unique physical properties, heat dissipating graphite sheets have become an ideal choice for solving hot issues.
1) Instantly uniform temperature, transforming "points" into "surfaces". When the chip is running, the heat is highly concentrated in a very small area (such as the CPU core), forming a local "volcano", causing the temperature in that area to soar sharply, triggering a frequency reduction. Artificial graphite sheets have a horizontal thermal conductivity of up to 1500-2000 W/m · K, which can quickly transform concentrated heat flow from the vertical direction into uniform heat flow in the horizontal direction.
2) Eliminate local overheating. When the temperature of the hotspot exceeds the threshold, the chip will actively reduce the frequency through "dynamic frequency adjustment" to protect itself, resulting in device lag and decreased computing speed. Graphite sheets are directly attached to the heat source, intervening in the heat transfer path as soon as possible, and dispersing the heat before it accumulates into a disaster.
3) Extremely thin and light, without taking up space. The interior space of modern electronic products (mobile phones, wearable devices, TWS earphones) is precious, and the thickness of graphite sheets can be as low as 0.015mm, making it easy to attach to small spaces such as chip surfaces, shielding covers, and flexible circuit boards. Can adapt to curved surfaces and irregular structures, perfectly fitting the shape of the heat source.
In addition, graphite sheets can serve as a "heat bridge" between chips, heat dissipation plates, and heat dissipation fins, quickly spreading hot spots to large-area heat dissipation components and improving the efficiency of subsequent convective heat dissipation. In areas where large heat sinks cannot be deployed (such as the back of a screen or the surface of a battery), graphite sheets can independently undertake hotspot diffusion tasks to prevent local temperature rise from affecting surrounding components. Enable the entire heat dissipation system (VC, heat pipes, graphite sheets, heat dissipation fins) to achieve a synergistic effect of "1+1>2".
