Traditional heat sinks or heat sink fins are not enough. To improve heat dissipation efficiency, Heat Pipe). [0003] Since the heat pipe has high heat transfer capability, high thermal conductivity, light weight, simple structure, and the like, and can transfer a large amount of heat without consuming power, it has been widely used for heat conduction of electronic components by using electronic heating elements. The rapid conduction of heat is performed to effectively solve the heat accumulation phenomenon of the electronic heating element at this stage. [0004] However, the conventional heat pipe has a cylindrical shape, and is formed by filling a capillary structure and a working fluid into a vacuum state in a metal pipe body, and absorbing and dissipating heat by a phase change of the working fluid. In modern electronic devices that are becoming shorter and lighter and thinner, the traditional cylindrical heat pipes not only take up space, but also have a small heat-receiving area. In addition, they are often blocked by other internal electronic components in the heat conduction path and cannot be equipped with heat-dissipating fins, so that the design of the heat-dissipating system Greatly restricted.

Another object of the present invention is to provide a flat-shaped heat pipe which is unilaterally enlarged, and the flat shell tube has a bent section to evade other electronic components to increase flexibility in design of the heat dissipation system. [0009] A further object of the present invention is to provide a flat-shaped heat pipe which is unilaterally enlarged, and the other end of the flat shell tube does not have an expansion section, which facilitates the setting of a plurality of fins and increases the heat dissipation efficiency. [0010] Compared with the prior art, the flat heat pipe of the present invention has an expansion section at one end, and the expansion section has a large heat conduction area with the heat generating component, so that the setting of the heat conduction block can be omitted, not only To meet the heat dissipation requirements, the installation space can be reduced, and the short and light design requirements of the product can be reduced. Moreover, the other end of the flat heat pipe of the present invention does not have an expansion section, which is convenient for setting a plurality of fins to increase heat dissipation efficiency. Moreover, the flat plate-shaped heat pipe of the present invention has a bending section, and the deflection section is arranged to avoid other electronic components, thereby increasing the flexibility of the heat dissipation system design.
