PURPOSE: A heat tube type solar energy collecting tube is provided to enable efficient transmission of absorbed radiant heat since evaporation diffusion type thermal medium is formed in an inner vacuum tube, and a thermal radiation projected tube is connected to the inner vacuum tube. CONSTITUTION: A heat tube type solar energy collecting tube comprises a double vacuum tube made of an outer vacuum tube(110) and an inner vacuum tube(120). The lower part of the inner vacuum tube is filled with an evaporation diffusion type thermal medium(10). A thermal radiation projected tube(130) is formed on the top of the double vacuum tube. The thermal radiation projected tube is inserted into the heat collection tank for transmission of solar radiation. The thermal radiation projected tube connects to the inner vacuum tube. A vaporization accelerating outlet(140) is put into the evaporation diffusion type thermal medium. The vaporization accelerating outlet has a thermal medium residue checking part(141).
