Significant heat pipes are usually borrowed from the circular pipe process, so the hair set in the pipe is easy to use in the circle due to any type of mesh or sintered body. In the process, the phenomenon of shape=process error occurs, and then m 跫 bias, looseness, etc., and then the process defect rate is high, and the finished product is serious; and the composite capillary structure is: And the precision and stability of the alignment between the two types of capillary structure, so it is conceivable that it must be solved to overcome: the project is difficult, and this is more complicated and difficult to see in the flat heat pipe Although the composite structure design has been seen, it is prudent to soften the y-type capillary structure—in fact, there is still a problem that it is difficult to make the specific defect rate high and the implementation or 瑕° does not conform to the benefits of better industrial utilization. Rsi 3 201202650 - Furthermore, since the height of the flat heat pipe is greatly reduced compared with the round pipe, the steam flow space is relatively reduced. Therefore, when it is introduced into the composite capillary structure, it has a certain volume thickness due to its distribution in the heat pipe. It will obviously cause the problem of insufficient steam flow guiding space, which will affect the heat transfer efficiency of the flat heat pipe. This part is also a subject that must be considered. Therefore, in view of the problems existing in the above-mentioned conventional flat heat pipes, how to develop an innovative structure that can be more ideal and practical is subject to the goals and directions of the relevant industry. • In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation of the above objectives, the inventor has finally obtained the practical invention.
