Problems solved by technology

However, due to the bulky size of this cooling device, it hinders the development of portable computers towards thinner and lighter
In addition, the industry also uses smaller fans to dissipate heat from the heat-generating electronic components of the system. However, the cooling effect it can achieve is not good, which reduces the operating efficiency of the portable computer and even causes damage to its internal components.

Description

technical field [0001] The invention relates to a portable computer, in particular to a keyboard backlight device for the portable computer. Background technique [0002] With the rapid development of technology, the portable computers currently on the market are generally designed with light, thin, short and small as the goal to meet the needs of the public. Due to the pursuit of high-efficiency products, the power of electronic components continues to increase, and how to dissipate heat in a limited and small space has become one of the first issues to be considered in the industry. [0003] At present, the industry adopts a heat dissipation device composed of a heat pipe, a heat sink, and a fan, which is thermally connected to a heat-generating electronic component of the system, such as a central processing unit (CPU), to discharge the heat generated by it. However, due to the large volume of the heat dissipation device, the portable computer is hindered from being thin...
