In this embodiment, the thickness of the wick 2 is 1 mm. In this embodiment, the pores of the wick's voids have any value between 50 μm and 900 μm, such as 100 μm; 200 mu m; 400 μm; 600 μm, etc. At present, the heat pipe is sintered by adopting copper powder, but the sintering of aluminum powder does not occur at present because the sintering of the aluminum powder is extremely difficult, and even sintered blocks of the aluminum powder are not sold on the market at home.
In the embodiment, the shell is made of an aluminum sheet, and the aluminum sheet of the embodiment is called a shell body 1; a liquid absorption core 2 is sintered in the middle of the shell body 1, and the shell bodies 1 on four sides of the liquid absorption core 2 are lapped together after being rolled up and are sealed through welding. The whole structure is that the shell body 1 is used for wrapping the liquid absorption core 2.

2) transferring the prepared slurry in the step 1) to an aluminum sheet, standing, bonding and forming; the aluminum sheet can be formed by a mold in an auxiliary manner, namely, the mold is placed on an aluminum sheet firstly, and then the aluminum sheet or aluminum alloy powder is kept stand for bonding and forming on the aluminum sheet and then the mold is taken away; the size of the aluminum powder or the aluminum alloy powder after bonding and forming under the action of the die can be controlled, so that the mass production can be better realized.
3) Putting the shell bottom filled with the slurry in the step 2) into a vacuum sintering furnace, evacuating air in the vacuum sintering furnace, raising the temperature of the vacuum sintering furnace to 580-660 ℃, and preserving heat for 1-10 min; and (5) cooling along with the furnace. Step 3) staged sintering: the staged sintering comprises the steps of raising the temperature of the vacuum sintering furnace to 500 ℃ of 400-; finally, the temperature is reduced to room temperature.
4) Cleaning the sintered body finished in the step 3) in an ultrasonic cleaning device, and boiling in pure water for 3-10 min; so that the surface of the sintered body is clean; the sintered body has a capillary structure.

And during sealing, rolling up the aluminum sheets which are more than the periphery of the sintered body, and welding and sealing the aluminum sheets.
When the clearance between the aluminum sheet and the sintered body needs to be removed, the aluminum sheets which are excessive on the periphery of the sintered body are coated with a layer of heat-conducting glue and then are mutually sealed and welded together. Or coating a layer of thin tin soldering paste on the aluminum sheets which are excessive out of the periphery of the sintered body, then rolling the excessive aluminum sheets to enable the aluminum sheets to be tightly attached to the sintered body for tin soldering, and then sealing and welding the aluminum sheets.
