The utility model discloses a carbon dioxide laser annular beam optical fiber tapering machine which comprises a laser light source box, one side of the laser light source box is fixedly connected with a light source carbon dioxide laser, and the light source end of the light source carbon dioxide laser emits laser beams. The laser beam is turned to the position above the laser light source box through a refraction mechanism, a red light mechanism is arranged at the top of the laser light source box, the laser beam and the red light mechanism form laser and red light rays, the laser beam and the red light mechanism form light spots, and how the annular light beam is generated is not elaborated. According to the carbon dioxide laser annular light beam optical fiber tapering machine, the annular light beam can be reflected to the reflecting mirror and then is emitted to the concave mirror through the reflecting mirror and the aperture, so that the annular light beam can be regathered into a light spot to be emitted to the workbench, laser and red light act at the same time for tapering machining, and therefore external interference factors can be greatly reduced; the temperature fluctuation range is small, and the effect of guaranteeing the product performance consistency and the high yield is achieved.

This utility model belongs to the field of heat dissipation technology, specifically relating to a loop heat pipe structure, including an evaporator, a condenser, and a liquid receiver. A liquid pipeline connects the condenser, liquid receiver, and evaporator, and the liquid pipeline contains a working fluid that circulates within the loop heat pipe structure. The evaporator is also connected to the condenser via a steam pipeline. A spiral guide vane is provided on the inner wall of the steam pipeline, and a cooling pipeline is coaxially fitted on the outer side of the steam pipeline to form a cooling channel. The cooling pipeline is connected to a cooling device and a circulating pump via a coolant pipeline. This utility model reduces steam flow resistance and improves condensation efficiency by setting spiral guide vanes within the steam pipeline. Especially in vertical pipe sections, it avoids localized overheating caused by steam stagnation. Furthermore, the cooling channel actively dissipates heat, preventing heat accumulation on the pipe wall and reducing the range of steam temperature fluctuations.
