Background Art

[0002] In production and living facilities, a lot of waste heat will be generated, such as kilns, industrial furnaces, flues of boilers, exhaust holes of central air conditioners, etc., and a large amount of waste heat will be discharged into the air with the smoke. Making good use of these waste heat can produce great energy-saving and environmental protection effects and better economic benefits. The use of these waste heat requires a heat conduction device; underground low temperature and geothermal heat also require a heat conduction device in the use of heat conduction and exchange; and some environments need to exchange their heat or low temperature with the external environment to adjust the temperature. Heat-conducting heat pipes are very practical heat-conducting devices for completing this heat exchange. Most of the existing heat pipe technologies are only suitable for heat conduction over long distances or heat exchange during liquid heating, and can generally only be used vertically or tilted, which greatly limits the application and effect of heat pipes. Therefore, it is necessary to propose an efficient and energy-saving heat-conducting heat pipe that is suitable for heat exchange in adjacent environments and can be used in horizontal conditions. Summary of the invention

[0003] The purpose of the utility model is to solve the above technical problems and propose a high-efficiency and energy-saving heat-conducting heat pipe that can be used horizontally. The heat pipe is provided with a sealed pipe body, a heat-conducting medium, a heat-conducting metal fin and a mounting fixing ring, and is provided with an improved inner pipe groove structure that enhances the heat-conducting function. The heat-conducting heat pipe is suitable for heat exchange in waste heat and geothermal utilization of kilns, industrial furnaces, boilers, central air conditioners, etc., and has the advantages of simple structure, convenient installation, good heat-conducting effect, better on-site adaptability, and can be used horizontally or vertically.

[0004] The utility model is realized by the following technical solutions:

[0006] The optimization scheme for further improvement and perfection of the utility model is:

[0007] The metal tube is a bent metal tube with several bends. The entire tube body is composed of several straight tube sections connected by bends. The tube sections are arranged in parallel, and the two metal tube openings are sealed or butted against each other. The outer periphery of each tube section is fixed with multiple metal fins perpendicular to the tube body. A fixing ring is provided in the middle part of the outer wall of each tube section.
