PURPOSE: To improve the capacity limit of thermal transference for the heat transferring tube by dividing the tube into the vapor passage section nd the condensed liquid passage section with a porous internal tube.
CONSTITUTION: A porous internal tube is coaxially mounted inside the body 1 of the heat transferring tube. The body is divided into the vapor passage section 8b and the condensed liquid passage section 8c with the internal tube. Therefore, the vapor and the condensed liquid in no way contacts each other thereby eliminating the limit to the heat transference otherwise caused by friction between the rising vapor and the lowering condensed liquid 6 through a vapor liquid two phase thermosyphon. Since the side wall of the internal tube 8 is prous, vapor bubble generated at the heating section 4 can move through the inside of the internal tube while the vapor at the heat removing section can go out of the internal tube 8. Thus, heat transference between vapor and liquid can be performed smoothly.
