熱元件的散熱。純銅本身具有非常高的熱傳導率（4. 0 1 W/ cm/K)，遠高於一般常見的金屬材料如··鐵（〇· 8 0 2W/cm/K) 、鎳（0.907W/cm/K)、鈦（〇.219W/cm/K)、鋁（2.37W/cm/K) ...等。純銅及其合金由於具有高熱傳導性質，故廣泛的 被應用於各式散熱元件内。 銅製熱導管之原理是利用冷卻劑（C ο ο 1 a n t )，在熱導 管之熱端受熱後蒸發變為氣態，其體積會急速膨脹並在管 内形成一種急速流動之氣流。此氣流會以高速往熱導管之Heat dissipation from thermal elements. Pure copper itself has a very high thermal conductivity (4.00 W / cm / K), which is much higher than common metal materials such as iron (0.80 2W / cm / K) and nickel (0.907W / cm / K), titanium (0.2219 W / cm / K), aluminum (2.37 W / cm / K), etc. Pure copper and its alloys are widely used in various heat sinks due to their high thermal conductivity. The principle of a copper heat pipe is to use a coolant (C ο ο 1 a n t). When heated at the hot end of the heat pipe, it evaporates to a gaseous state, and its volume will expand rapidly and form a rapidly flowing airflow in the pipe. This airflow is directed at the heat pipe at high speed.

Description of the invention (2) After flowing in the direction of the cold end and condensing into supersaturated vapor or liquid at the cold end tube wall, it will flow back to the hot end of the tube through the capillary phenomenon of the tube wall. In this way, the coolant in the heat official is circulated endlessly due to heat and cooling, and the heat of the heating elements in the computer is removed. #The key technology for making heat pipes is that the inner wall of the heat pipe must be made into a thick chain surface to improve the capillary phenomenon of the fluid (coolant) and increase the thermal efficiency. In order to achieve the above-mentioned goals, today's products have a variety of methods. For example: the inner surface of the original smooth copper pipe, or the groove, or etching to roughen the two surfaces, or embossed, or in the copper pipe The fine metal-filled mesh is in contact with copper ^^ to increase the capillary flow effect on the inner wall of the copper pipe. Among them, the most popular type used today by the Emirates & is a fine metal mesh filled in copper pipes. Common thermal guidance: the appearance can be flat or round f. For example, t, the existing ί = use pure copper, put the rolled metal mesh before it, and touch the area 7; J is pressed into a flat shape to increase the filling of the connection between the heat pipe and the heat dissipation element ^, Heat transfer efficiency. After that, in the vacuum and low-pressure state, gas welding the square six, ~ 郃 f, and then pressure-tightly close the nozzle, then arc welding or ',' to seal the nozzle and achieve air-tight. ^ ^ ^ ^ ^ ^ ^ t ^ f ^ ^ ^ t tucked into a cylindrical shape :: the most commonly used method of genus 2 is to fill capillary flow in copper pipes: ΐ; genus: and copper pipe: wall connection, In order to achieve the above-mentioned enhancements, first, the shortcomings in the process of copper pipe 此: this existing 'will be described below. And thus seriously affect its effectiveness. For example, if Nie IΓ ’s official network is abnormally distorted, deformed, or tweaked, a fine metal network is formed during the pressing process and is unevenly distributed in the tube. 200306898 _ Case No. 91134022 Explain the phenomenon of (3). At this time, not only the heat pipe may be blocked, but also the copper mesh and the inner wall of the copper pipe may be peeled off in some areas, resulting in a decrease or failure of the heat pipe. Secondly, using this traditional process will increase the diameter of the heat pipe produced by it, and the probability of the copper mesh and the inner wall of the copper pipe peeling will increase, which will cause its yield to decrease. Finally, if the heat pipe needs to be bent and deformed due to the requirements of the use specifications, this will cause the heat pipe to easily block and prevent airflow during the bending process, or the copper mesh and the inner wall of the copper pipe peeling off to cause capillary flow. Causes the effectiveness of this heat pipe to decrease or fail. SUMMARY OF THE INVENTION The present invention is a method for manufacturing an inner conductive layer of a heat pipe by a brazing process. In the invention, a brazing process is used to fix the metal mesh (or metal wire) and then to the inner pipe wall of the heat pipe, so as to effectively avoid the metal mesh (or metal wire) and the inner pipe of the heat pipe in the subsequent manufacturing or use process. Peeling or displacement of the wall. The heat pipe produced by this method can effectively improve the heat dissipation efficiency, reliability in use and process yield of the heat pipe. The invention is completed by the following steps: (i) placing the brazing filler on the inner pipe wall of the metal pipe; and (ii) placing the metal mesh (or metal wire) on the brazing filler. Interposed between the inner wall of the metal pipe and the metal mesh (or metal wire); and (iii) the brazing process of the above metal pipe to join the metal mesh (or metal wire) to the inner tube wall of the metal pipe. Embodiment: A method for manufacturing an inner conductive layer of a heat pipe by a brazing process. Use this
