Description

The present invention relates to a heat-tube heat dissipation structure, and more particularly to a heat-tube heat dissipation improvement structure that has good heat conduction efficiency and can receive an impact of a relatively large heat output.

  In recent years, electronic technology has rapidly developed, and the high frequency and high speed of electronic members and the density and miniaturization of integrated circuits have drastically increased the amount of heat generated by unit volume electronic members. Known heat dissipation methods include methods such as heat dissipation fins, heat tubes, and heat conduction interfaces. How to improve the heat dissipation efficiency, solve the heat wax generated by the electronic member, and prevent the high temperature and high temperature generated by the increase in the density of the integrated circuit from causing the electronic member to be damaged are the current important issues. It has become.

  The heat pipe is a heat conducting member that realizes heat conduction with its own internal working fluid, has characteristics such as high heat conductivity and excellent temperature uniformity, has a good heat conduction effect, and is applied in a wide range. In addition, the heat tube technology is suitable for solving the heat dissipation problem caused by the improvement in performance of current electronic members due to its features such as high efficiency, closeness and precision reliability.

  The known heat tube can dissipate the amount of heat of the electronic member to a remote location, but other problems are also caused by stretching, that is, the capillary structure on the chamber wall surface of the known heat tube is finite, and the evaporation unit is relatively opposed. Since the working fluid adsorbed by the upper capillaries is limited, when the evaporation part of the heat tube adsorbs the heat generated by the relatively high power electronic member, there is often a large amount of capillary working fluid on the evaporation part. Heat pipe that can not process heat, causes dry firing, expires the heat conduction performance of the heat tube, burns out due to inability to dissipate the electronic components in a timely manner, and thus enhances the liquid transmission capacity of the capillary structure, and the heat tube with higher heat conduction performance The design of this is a problem for those skilled in the art to solve.

As mentioned above, the known art has the following disadvantages:
1． Poor heat transfer efficiency;
2． Because the unit area of the capillary structure of the evaporation section is finite, it cannot withstand the effects of greater heat output;
3． The amount of heat conduction is finite.

  Therefore, how to solve the problems and deficiencies of the prior art is where the inventor of the present application and related manufacturers engaged in this industry want to improve their research.
