After the flat water vapor condensate 79, some water 79 will remain in the heat dissipating section c.

(3) Drop, this situation has 5 [new content] The main purpose of this creation is to provide a flat heart that can effectively cope with the inner temperature of the tube that can be encountered by the flat heat pipe. & ask questions, and maintain 1 〇 flat open, ^ '5 to achieve the above purpose 'Based on the creation of a flat hot official, including · tube body, both ends = for the seed two = wall, from the liquid Filling in the tube _ ; _ at least - the flat section, and at least one of the more than one body 疋 = the water clogging of the liquid inside the flat heat pipe is equal to the temperature uniformity, and has a more conventional flat heat pipe Better thermal conductivity. [Embodiment] In order to explain the structure and characteristics of the present invention in detail, a preferred embodiment is described with reference to the following, wherein: < as shown in the first to second figures A flat heat pipe 10 of 2 is mainly composed of a pipe body 1 J, which is composed of: (3) U, a capillary structure h, and a liquid body 11, which are closed at both ends. The pipe body U is made of steel. The capillary structure 2 is disposed on the inner wall of the tube body u. The capillary structure 21 may be a copper powder sintered, or a metal mesh, or a M318115 groove provided in the pipe body n, which is exemplified by a copper powder sinter, and other metal mesh forms or The groove shape is a conventional technique, and the detailed composition of the capillary structure 21 is not the technical focus of the present invention, and will not be described. The liquid 31 is filled in the tube body 11. The tube body 11 defines a relatively flat section 12 and a higher section 14. The flatter section 12 is located at one end of the tubular body 11, and the upper section 14 is located at the other end of the tubular body 11, i.e., the end of the tubular body U. Moreover, the diameter of the capillary structure 21 of the upper section 14 is larger than the diameter of the capillary structure 21 of the relatively flat section 12. The tube body η further defines a heated section Η and a heat dissipating section C which covers the partial flat section 12 and is connectable to a heat generating device (not shown). The heat sink segment c covers the higher, 14 and the local touch (four) segments 12. That is, the remainder c is a combination of the souther section 14 and the partial flat section 12. With the foregoing structure, at (4), the 'position_heated section Η (i.e., the portion of the flat section 12) (10) is heated to evaporate into the vapor, and the squeaking "_ to the heat-dissipating section is enclosed by the capillary structure 21 c, and in the segment c re-condensed into the liquid 31 into the setting of the capillary, the capillary in the upper section 14 is large, so the liquid basin condensed in the capillary structure 21 is insufficient to block the capillary The space enclosed by the structure 21 is not in the condition of q =. As can be seen from the second figure, the liquid 31 condenses in the shape of the hair J. Thus, the liquid 31 can be heated by the burrs and the 冓 冓. (4) There is good _ guo guo, ^ ^ ^ flow to the nature, good thermal conductivity. And then have a good average temperature 20 M3l8ii5 Please refer to the third figure, the heat pipe of this embodiment The fins 41 are disposed on the surface of the tube body u and located in the heat dissipating portion C, that is, the heat dissipating fins 41 are close to the upper portion 14. The fourth to fifth figures are The arrangement of the other heat dissipating fins 41 is shown. 5 The structure of the above-mentioned additional heat dissipating fins 41 is mainly to strengthen the heat dissipating section c. The thermal effect. ' It should be added that the position and definition of the flat section 12 and the upper section 14 of the tube 11 of the present invention may be different. For example, a tube may be formed on both ends of the tube body. The high section has a relatively flat section in the middle, and the modification of the above-mentioned 10 embodiment is implemented as an equivalent change of the patent application scope of the creation, and should be covered by the scope of the patent application of the creation. It can be seen that the effect that can be achieved by this creation is: “1. Solving the problem of water accumulation and uniform temperature in the conventional flat heat pipe: Μ, the design of the higher section of the age can make the button stay in the capillary structure of the heat dissipation section. When it does not block in the space enclosed by the capillary structure, it does not have the problem of blocking the internal space of the pipe body, thus effectively solving the problem of Xi Erping.
