If the gap 110 is caused by the working medium, the content of the working medium is insufficient and the heat transfer performance is insufficient. In the case where the volume of the pores in the powder 100 is the same as the percentage of the solid volume of the powder, that is, the same, please refer to the second diagram A and the Figure 2B, respectively, in the paper of the National Institute of Science and Engineering, National Institute of Science and Engineering, Department of Science and Engineering, Lin Yueru, the paper, "Pore Structure, Effect of Catheter Performance", pages 62, 61, compare the second A The microscopic structure of the embryos of the embryos and the low-temperature sintering of the graphs and the graphs of the low-temperature sintering. The knots are known: the micropores 110 that are unpredictable under low-temperature sintering conditions are completely old, and can only be eliminated under high-temperature sintering conditions. t 不 水 水 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不It has a sintered capillary structure. And working medium·. Compared with the prior art, the sintered spherical tube of the spherical metal powder of the fourth body can reduce the effective porosity of the leather tube and effectively solve the pores inside the capillary structure. Advance and improve heat pipe performance. There are a large number of residual micropores caused by the ship's stalks. [Examples] Capillaries include fresh-keeping bodies, heart-shaped particles that are embedded in the tube body, and Ding Lu (four) soil filled in the tube body: Miscellaneous (4), the city through the following steps fill the gap between the apparent density of 3.3gj3 = and ^ between the gap, in the above 300, through the sintering process to form holes, _ as the main spherical metal powder particles inside the micro The pores have high capillary forces and I ^ capillary particles to reduce the energy of the metal powder. . ..., the effect of bad transmission, effectively improve the heat pipe. In one embodiment of the sintered heat pipe, the spherical metal powder is mechanically cut,
