With the rapid development of technology in the industry, coupled with the emergence of a strong wireless network, it will be integrated into all the multimedia devices in the home to achieve the goal of multi-functional multi-function development. The product is lighter and thinner with more functions, so heat dissipation becomes the most important. Key technology. Special heat dissipation systems such as fan heat fan, fan heat module, fan heat paste, fan heat sheet, heat pipe, small motor, design, etc. There is no fan that I can't do.
