Description

Technical Field

[0001] This utility model relates to the field of solar energy technology, and in particular to a conical metal heat pipe for use in solar collectors. Background Technology

[0002] In applications of solar gravity heat pipes, the condenser section is placed inside a metal blind tube. Heat is transferred from the heat pipe to the medium that needs to be heated through the metal blind tube. The condenser section and the metal blind tube of the metal gravity heat pipe need to be tightly fitted, and the smaller the gap, the better. For the same heat exchange area, the condenser section with a larger contact area has a higher heat transfer efficiency. The condenser section of a traditional gravity heat pipe is cylindrical, and the matching metal blind tube is also cylindrical. Assembly is achieved through a gap. If the gap is too small, it is difficult to insert the condenser section into the metal blind tube, making assembly difficult. If the gap is too large, it will reduce the heat transfer efficiency.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see the appendix Figure 1 - Appendix Figure 6 This utility model provides an embodiment of a conical metal heat pipe for a solar collector, comprising a manifold 3, within which a conical metal blind tube 7 and a metal gravity heat pipe 6 are disposed. The metal gravity heat pipe 6 consists of a conical condensing section 61 and an evaporating section 62, with the conical condensing section 61 fitted inside the conical metal blind tube 7. An insulation layer 8 is provided on the inner wall of the manifold 3 to reduce heat loss and improve thermal efficiency. Aluminum fins 5 are provided on the outer wall of the evaporating section 62 to increase heat transfer efficiency. The heat exchange area is increased to improve heat exchange efficiency; a glass vacuum solar collector tube 4 is fixedly connected to the manifold 3, and a metal gravity heat pipe 6 is installed inside the glass vacuum solar collector tube 4; a pressurized heat pipe solar water heater 2 is fixedly connected to the manifold 3; a bracket 1 is fixedly connected to the pressurized heat pipe solar water heater 2, which is used to support and fix the pressurized heat pipe solar water heater 2 and the glass vacuum solar collector tube 4; an inlet 9 and an outlet 10 are provided on one side of the outer wall of the pressurized heat pipe solar water heater 2.

[0022] Working Principle: When using this invention, solar radiation energy is first absorbed by the glass vacuum solar collector tube 4 and converted into heat energy. This heat energy is transferred through the collector tube wall to the evaporation section 62 of the internal metal gravity heat pipe 6. The working fluid in the metal gravity heat pipe 6 evaporates in the evaporation section 62, carrying heat energy to the conical condensation section 61. In the condensation section, the working fluid condenses upon cooling, releasing heat energy. Since the conical condensation section 61 is fitted inside the conical metal blind tube 7, the two are tightly fitted, so the heat energy can be efficiently transferred to the water in the manifold 3. After absorbing heat energy, the water in the manifold 3 rises in temperature and is then stored by the pressurized heat pipe solar water heater 2. Users can inject cold water through the inlet 9 and obtain hot water through the outlet 10 of the water heater to meet their daily hot water needs. The insulation layer 8 on the inner wall of the manifold 3 effectively reduces heat loss and ensures efficient utilization of heat energy. At the same time, the conical design allows the metal heat pipe condensation section to be easily and accurately inserted into the metal blind tube, achieving a reliable tight fit and further improving heat transfer efficiency.
