[0002] The heat pipe is an important part of the solar collector, which directly affects the service life and heat conversion efficiency of the solar collector. At present, most of the existing solar collectors use a vacuum heat collector structure, and the heat pipe is mainly made of an aluminum tube. Composed of U-shaped tubes, U-shaped tubes are deformed when subjected to cold and heat shocks, and the stress is transmitted to the vacuum tubes, causing the vacuum tubes to burst. However, some existing heat collecting tubes composed of inner tubes and outer tubes have solved the problem of vacuum tube bursting. problem, but there is a large gap between the outer tube and the inner tube, the utilization rate of the outer tube is low, and the heat transfer efficiency is low

The invention discloses a medium-temperature solar heat pipe device, and mainly relates to the technical field of solar energy. It includes a heat pipe, the heat pipe is provided with a first inner pipe, a second inner pipe and a U-shaped connecting pipe, the cross section of the first inner pipe and the second inner pipe is surrounded by a line segment and an arc, The arc surfaces on the first inner tube and the second inner tube are close to the inner wall of the heat-conducting tube, the planes on the first inner tube and the second inner tube are away from the inner wall of the heat-conducting tube, and one end of the U-shaped connecting tube is inserted into the first The inner tube is connected to the first inner tube, and the other end is inserted into the second inner tube to connect with the second inner tube. Several buffer springs are arranged between the plane of the first inner tube and the plane of the second inner tube. The end of the first inner tube far away from the U-shaped connecting pipe is provided with a first connecting round pipe, and the end of the second inner pipe far away from the U-shaped connecting pipe is provided with a second connecting round pipe. The invention has the beneficial effects of preventing the vacuum tube from bursting and improving the heat conduction efficiency.
