Example Embodiment
[0047] [Example 1]
[0048] Step A: such as figure 1 As shown, one end of the tube shell 1 is reduced in diameter to form a shrink head 11, and the other end is a tail. You can choose to chamfer the inner or outer corners of both ends of the shell 1.
[0049] Step B: Combine figure 2 , Combine the metal mesh 2 with the tube shell 1, the outer diameter of the metal mesh 2 matches the inner diameter of the shrink head 11, and the shrink head 11 and the metal mesh 2 are fixed by welding.
[0050] Step C: Combine image 3 , Combine the core rod 3, the auxiliary metal mesh 2 and the inner wall of the tube shell 1 to maintain a relatively uniform gap 4 to facilitate powder filling; fill the gap 4 with an appropriate amount of metal powder, and then separate the core rod 3 from other elements.
[0051] Step D: Put the workpiece obtained in the previous step into a sintering furnace, and implement sintering under the protection and reduction of protective gas and reducing atmosphere. After...

[0078] [Example 2]
[0079] In Example 1, the process route that can realize bending (flattening) first and sintering later has been given. Obviously, the manufacturing method of heat pipes can be more comprehensive with the manufacturing process of heat pipe radiators of various common structures. The combination. Although this embodiment can better integrate the manufacturing methods of heat pipes and heat pipe radiators compared with Document 17, it does not mean that all heat pipe radiators included in the present invention are manufactured by such methods. Generally speaking, this The invention first uses the heat control as a finished product, and then uses the existing technology to make a heat pipe radiator. This embodiment mainly provides a method for manufacturing different types of heat pipe radiators.
[0080] Combine Figure 7 with 8 Take the common (tower CPU) radiator 7 as an example. Generally, the tube shell 1 filled with powder in embodiment 1 is shrunk, welded,...
Example Embodiment
[0086] [Example 3]
[0087] Combine Picture 9 , The left end of the tube shell 1 is sealed and welded, and then the metal mesh 2, the core rod 3, the funnel 6, and the tube shell 1 are combined and filled with powder. The metal powder enters the gap 4 from the gap between the positioning blocks 62. If the metal mesh 2 includes a wound metal mesh, the metal mesh can be optionally wound on the core rod 3.
[0088] After filling powder, disassemble the positioning tooling. If the mandrel 3 is separated first, the funnel 6 is fixed, and the positioning block 62 and the end surface 63 of the funnel 6 can block the metal mesh 2 to prevent it from moving. If the funnel 6 is separated first, use a washer (used with bolts) and similar tools to insert the mandrel 3, block the metal mesh 2, and take out the mandrel 3.
[0089] The workpiece containing metal powder is sintered, and then other processes are completed.
[0090] In particular, after separating the mandrel 3, you can choose to fil...
