Heat pipes must meet several conditions:
1, a liquid that can "evaporate-condense" well at room temperature;
2. There should be enough horizontal height difference between the heat source and the condensation place;
3, the tube should be as vacuum as possible to form a volume space for liquid evaporation;
4. It is better to have capillary grooves on the inner wall of the tube, so that the liquid at the condensation place can flow back quickly.
Back to the heat source;
5. Strictly seal.
Hehe, the above are some theories of designing heat pipes after refining. Do you think you can do it? Hehe ~ ~ you can't do it without certain professional equipment and environment, brother.
