technical field [0001] The invention relates to a flat heat pipe, in particular to an innovative shape design of a flat heat pipe structure with composite capillary structure. Background technique [0002] In terms of heat pipe structure design, in order to achieve a better effect of condensate return and transport, capillaries are usually added inside the heat pipe to achieve its purpose.

Problems solved by technology

[0004] Although the composite capillary structure design can obtain a better condensate diversion effect, it faces relatively greater difficulties and problems in the manufacturing process, especially when it is applied to the flat heat pipe structure, the difficulties and problems will be more prominent Significantly; Gein, flat heat pipes are usually formed by flattening circular pipes. Due to this deformation process in the manufacturing process, the capillary structure in the tube is often easy to be formed in a round shape, whether it is in any shape such as mesh body or sintered body. During the pipe flattening process and the vacuum sealing process, defect errors such as deformation, deviation, and looseness occur, which in turn cause serious problems such as a high defect rate in the process and difficult control of the quality of the finished product; and the composite capillary structure , since it further involves technical items such as alignment accuracy and stability between the two capillary structures, it is conceivable that the problems to be solved and overcome are bound to be more complicated and difficult, and this is the current flat heat pipe. Although the design of composite capillary structure has been seen, in fact, there are often problems that it is difficult to implement the specific manufacturing or the defect rate is high, which does not meet the best industrial utilization benefits.

[0005] Furthermore, since the internal height space of the flat heat pipe is greatly reduced compared with that of the round pipe, the steam guiding space is relatively reduced, so when it is introduced into the design of the composite capillary structure, because it is distributed in the heat pipe and has a certain volume thickness, it will obviously cause steam Insufficient reduction of the diversion space will further affect the heat conduction performance of the flat heat pipe. This part is also a topic that must be considered.
