Flat Heat Pipe Radiator and Portable Computer

摘要

A flat heat pipe radiator and a new kind of portable computer are provided. The air convective extended heat exchange surface of the radiator surrounds the fan impeller and is facing the air outlet of the impeller, the heat transport distance in heat pipe is shortened, the fan shell and the diffusion channel in the shell can be left out, so the size, weight and cost of the radiator are decreased effectively. The restrictions to a radiator when installing are reduced, which helps to implement the standardization of the radiator series. The new kind of portable computer helps to decrease weight and thickness and improve the heat dissipation further.
