[0025] Refer to Figures 1 - 4, an embodiment provided by the present utility model: a stainless steel heat pipe, including an upper cover plate 1 and a lower cover plate 2. An inner cavity 3 is provided at the connecting position of the upper cover plate 1 and the lower cover plate 2, and a liquid injection port 4 communicating with the inner cavity 3 is provided at one end of the connecting position of the upper cover plate 1 and the lower cover plate 2. The thickness of the upper and lower cover plates can be 0.2 mm - 0.3 mm. The liquid injection port 4 is circular. The setting of the liquid injection port 4 can inject a liquid heat transfer medium into it. At the corresponding positions of one end of the upper cover plate 1 and the lower cover plate 2 and the liquid injection port 4, a liquid injection frame one 5 and a liquid injection frame two 6 are respectively fixedly connected. A liquid injection slot 7 is provided at the connecting position of the liquid injection frame one 5 and the liquid injection frame two 6. The liquid injection slot 7 is also circular. The liquid injection slot 7 is communicated with the liquid injection port 4. A section of the connecting position of the liquid injection slot 7 and the liquid injection port 4 is in an arc-shaped concave form. When pressing and cutting after liquid injection, the tightness of the seal can be ensured. The liquid injection slot 7 can also insert an air pipe for airtightness monitoring work. The inner diameter of the opening position is large, and the inner diameter of the inner side position is small. After the air pipe is inserted into it, stable positioning can be achieved, and the air hole docking can be ensured to be tight, which is convenient for airtightness monitoring work. An upper positioning bracket 9 and a lower positioning bracket 10 are respectively arranged in the inner cavity 3. The upper cover plate 1, the lower cover plate 2, the upper positioning bracket 9, and the lower positioning bracket 10 are all made of stainless steel. The stainless steel material not only has a certain heat conduction effect to achieve a stable heat equalization effect, but also enables the entire heat pipe to have good structural stability, is not easy to deform and break, and enhances the structural stability. A positioning slot 11 is arranged inside the connecting position of the upper positioning bracket 9 and the lower positioning bracket 10. A capillary copper sheet 12 is arranged in the positioning slot 11. An air passage 13 is arranged on the capillary copper sheet 12. A plurality of air passages 13 are arranged and evenly distributed on the capillary copper sheet 12. The thickness of the capillary copper sheet 12 can be 0.02 mm - 0.08 mm.
