Problems solved by technology

[0002] With the high integration of electronic products, the computing speed and frequency are getting higher and higher, and electronic devices often generate a lot of heat locally, resulting in excessive local temperature, which makes the function of electronic devices invalid or even destructive, shortening the Electronic device service life
The lightness and thinning of modern electronic products requires that the heat sink cannot be made too large or too heavy. Due to the limitation of the structure and shape of electronic devices, direct contact between the heating device and the heat sink is often impossible, which seriously affects the heat dissipation speed and efficiency.
In addition, in traditional heating equipment, heat is required to be transmitted to an ideal position in time, but the heat generated by current heating equipment is mainly transported through heat contact conduction and air convection heat conduction, which is inefficient and has a large temperature gradient. The heat transfer is not uniform, and it is urgent to improve the heat conduction efficiency
