Description
Technical Field
[0001] The invention relates to the technical field of solar water heaters, and in particular to a water heater using an inner tank heat conduction type heat pipe solar collector. Background Art
[0002] There is a water heater using a heat pipe solar collector. The heat pipe is a flat-plate solar collector, which includes a shell, an upper glass cover, a heat collecting plate core, an insulation layer and a bottom plate. The heat collecting plate core includes a plurality of heat pipe flow channels parallel to each other in the vertical direction. The evaporation end flow channel of the heat pipe is welded and connected to the heat absorbing plate. The condensation end of the heat pipe extends to the outside of the shell of the flat-plate solar collector. The water heater tank includes an inner tank. The inner tank has a plurality of uniform holes arranged side by side on the same straight line. Blind pipes of the same angle are welded in the holes. The condensation ends of the heat pipes are respectively inserted into the corresponding blind pipes. The cavities of the blind pipes and the condensation ends of the heat pipes are filled with thermal conductive silicone grease. The scheme is that the outer wall of the blind pipe is in direct contact with the water to achieve heating of the water in the water tank. The problem with this structure is that after the water tank has been in operation for a long time, since the blind pipe is built into the inner tank of the water tank and is in direct contact with the water, the blind pipe has a small heat conduction surface and the heat is concentrated, which makes it easy for scale to form on the outer wall of the blind pipe. Since scale is a poor conductor of heat, the heat at the condensation end of the heat pipe cannot effectively transfer heat to the water in the water tank after scaling, which greatly reduces the heat collection effect of the solar collector during later use.
[0003] Therefore, it is necessary to provide a water heater using an inner tank heat-conducting heat pipe solar collector to solve the above technical problems. Summary of the invention
[0004] The purpose of the present invention is to provide a water heater using an inner-tank heat-conducting heat pipe solar collector in view of the deficiencies in the prior art, which will not produce scale during long-term use and ensures the heat collection efficiency of the heat pipe solar collector.
[0005] To achieve the above object, the technical solution adopted by the present invention is:
[0006] A water heater using an inner tank heat conduction heat pipe solar collector comprises a water tank, a bracket and a heat pipe solar collector, wherein the water tank is mounted on the upper end of the bracket, and the heat pipe solar collector is tiltedly mounted on the lower end of the bracket, wherein the water tank comprises an outer shell and an inner tank, and an insulation layer is filled between the outer shell and the inner tank, and a plurality of heat conduction blocks are evenly arranged along a straight line on the outer side of the bottom of the inner tank, wherein the cross section of the heat conduction block is T-shaped, and the heat conduction surface on the top of the heat conduction block is an arc surface, and the heat conduction surface is closely fitted with the outer wall of the inner tank, and the heat conduction The heat block is provided with a heat pipe socket, the open end of the heat pipe socket is arranged at the bottom of the heat conductive block, a plurality of heat conductive sheets are arranged around the outer periphery of the heat pipe socket, the heat pipe socket is connected to the heat conductive surface through the heat conductive sheets, the heat pipe socket is a tapered hole, the outer periphery of the open end of the heat pipe socket is provided with an external thread, the condensing end of the heat pipe of the heat pipe type solar collector is inserted into the heat pipe socket, the heat pipe is provided with an internal thread fastener that slides along the heat pipe, and the condensing end of the heat pipe is pressed and set using the internal thread fastener that cooperates with the external thread of the heat pipe socket.
[0007] Preferably, thermally conductive glue is coated between the inner wall of the heat pipe insertion hole and the outer periphery of the heat pipe condensation end.
[0008] Preferably, the condensing end of the heat pipe is a conical head adapted to the heat pipe socket.
[0009] Preferably, the heat conductive block is an aluminum heat conductive block or an iron heat conductive block.
[0010] Preferably, heat-conducting glue is coated between the outer wall of the inner tank and the heat-conducting surface of the water tank.
[0011] Preferably, mounting holes are provided at both ends of the heat conducting surface of the heat conducting block, bolts corresponding to the mounting holes are fixed to the outer wall of the inner tank, and the heat conducting block is pressed and fixed to the outer wall of the inner tank by nuts.
[0012] Preferably, the number of the heat conducting blocks is equal to the number of the heat pipes.
[0013] Preferably, the heat conducting surface, the heat pipe jack and the heat conducting sheet of the heat conducting block are integrally formed. Compared with the prior art, the present invention has the following advantages:
[0014] 1. The heat-conducting block structure of the present application is greatly improved compared with the existing heat-conducting blocks or blind tube structures. Compared with the existing heat-conducting blocks, the cross-section of the heat-conducting block is designed to be T-shaped, which greatly increases the area of the heat-conducting surface and relatively reduces the contact temperature between the heat-conducting block and the inner tank, making it difficult for the inner tank and the heat-conducting block to form scale at the contact point; compared with the blind tube structure, the heat-conducting block does not directly contact the water inside the inner tank, so there will be no scaling on the surface of the heat conductor. At the same time, due to the large heat-conducting surface and the dispersion of heat, scaling will not form on the inner wall of the inner tank, ensuring that the heat-conducting block always maintains a high heat-conducting efficiency when the water heater is running for a long time.
[0015] 2. The outer periphery of the heat pipe socket is connected to the heat conduction surface through the heat conductive sheet, so that the heat at the condensation end of the heat pipe is efficiently transferred to the heat conduction surface through the heat pipe socket, thereby improving the heat transfer efficiency and the utilization rate of thermal energy.
[0016] 3. External threads are directly arranged on the periphery of the heat pipe socket of the heat conductive block, and the external threads on the periphery of the heat pipe socket are directly matched with the internal thread fasteners. The condensation end of the heat pipe is pressed by the internal thread fasteners, so that the condensation end of the heat pipe is more closely contacted with the inner wall of the heat pipe socket, thereby improving the heat conduction effect.
