Problems solved by technology

Generally, the diameter of the outer edge of the heat pipe is not large, and it is quite difficult to cover the splitter with capillary tissue, and this combined structure must be placed inside the metal pipe and attached to the inner wall of the metal pipe, so that It makes the production of heat pipes more difficult

[0040] The invention provides a special metal pipe for heat pipe, such as image 3 As shown, the metal tube 10 mainly includes a tube body (Tube) 100, two partition plates 101, 102 extend from the inner wall of the tube body 100, and a gas channel 11 (Vapor Channel) is formed to partition the inside of the tube body 100 And the liquid channel 12 (Liquid Channel); the length of the liquid channel 12 of the present embodiment is less than the length of the gas channel 11, so that the first and last ends of the gas channel 11 are respectively formed with a communication zone 13 (such as Figure 4 shown).

[0041] Please refer to Figure 1 to Figure 4 As shown, they are respectively the flow chart of the first manufacturing method of the metal pipe of the present invention; the radial cross-sectional schematic diagram before being processed by the forming tool in the first embodiment of the pipe body of the metal pipe of the present invention; the metal pipe of the present invent...

[0048] Please refer to Figure 7 to Figure 9 Shown is the flow chart of the second manufacturing method of the metal pipe of the present invention; the radial cross-sectional schematic diagram of the second embodiment of the pipe body of the metal pipe of the present invention; Figure 8 Schematic diagram of the radial cross-section of the middle tube body after being processed by the press tool. The production method of this embodiment replaces the step b) of the above-mentioned first embodiment with step b'). The inside of 100 is separated and formed with gas channel 11 and liquid channel 12 (such as Figure 8 , Figure 9 shown); in this step, the upper and lower clamping pressure tools (not shown) are pressed against the outer surface of the pipe body 100, so that the end faces of the two upright partition plates 101, 102 are mutually It is bonded and sealed, and a gas channel 11 and a liquid channel 12 are formed inside the tube body 100 .

[0051] Please refer to Figure 10 and Figure 11 Shown, respectively is the radial section schematic diagram of the third embodiment of the pipe body of the metal pipe of the present invention and Figure 10 The schematic diagram of the radial cross section of the middle pipe body after being processed by the press tool. The difference between it and the second embodiment is that this embodiment is in the form of a single upright partition plate 101, and the outer surface of the pipe body 100 is processed by a press tool. Press and hold, so that the end surface of the partition plate 101 and the inner wall of the tube body 100 are bonded and sealed together, and a gas channel 11 and a liquid channel 12 are formed inside the tube body 100; and the gas channel 11 and the liquid channel 12 are in the tube body The first and last ends of 100 are connected to each other (not shown in the figure); thus, it also has the equivalent effect of the above-mentioned embodiment.

Abstract

The invention discloses a special metal pipe for heat pipes, and a manufacturing method thereof, wherein the metal pipe comprises a pipe body; at least one separation plate is extended from the inner wall of the pipe body; the separation plate separates the inside of the pipe body to form a gas channel and a liquid channel; and the head end and the tail end of the gas channel and the liquid channel are mutually communicated. As the gas channel and the liquid channel are directly molded inside the metal pipe through the separation plate, the metal pipe and the manufacturing method thereof can effectively avoid the dry-out damage of a heat pipe, improve the heat-conducting speed and effectiveness of the heat pipe and greatly raise the manufacture qualification ratio of the heat pipe.

Description

technical field [0001] The invention relates to a metal pipe, especially a special metal pipe for heat pipes; the invention also relates to a manufacturing method of the special metal pipe for heat pipes. Background technique [0002] As the computing speed of the central processing unit (CPU) of the computer continues to increase, the heat generated by it is also getting higher and higher. In the past, the heat dissipation device composed of an extruded aluminum radiator and a fan cannot meet the requirements of the current central processing unit. Therefore, people in the industry have successively developed heat pipes with higher thermal conductivity and combined them with radiators to effectively solve the heat dissipation problem at this stage; however, the structural design inside the heat pipe How much it is with the working fluid will be related to the heat conduction speed and heat conduction efficiency of the heat pipe. When the working fluid is too much, the gas c...
