[0032] Reference Figure 1-4 A heat transfer and exchange structure of a solar thermal collector made of special-shaped materials, comprising: a collector 1, which is arranged in a closed manner and has a heat storage chamber 7 for storing heat energy inside. It is considered to use special-shaped materials with good thermal conductivity and high-temperature resistance, such as special alloys or ceramic materials. These materials can work stably in a high-temperature environment and are conducive to the transfer and concentration of heat. The design of the heat collecting pipe of the special-shaped material can enhance its absorption capacity of solar radiation through surface treatment or coating, so as to achieve efficient heat absorption; a frame 2, which is installed on the surface of the collector 1, and has a heat collecting pipe 5 for conducting heat energy to the collector 1 inside the frame 2; a reflective part 8, which is rotatably connected to the frame through a rotating part 13 2, and is configured to be able to rotate around the axis of the rotating part 13, so that the reflecting part 8 can effectively reflect the solar energy to the position of the heat collecting tube 5 for the heat collecting tube 5 to absorb the solar energy; the surface of the frame 2 is installed with a driving mechanism and a cleaning mechanism connected to the surface of the driving mechanism and movable in the horizontal direction. The collector can be cleaned to a certain extent by the cleaning mechanism to avoid dust and impurities adhering to the surface of the collector after working for a long time and affecting its absorption of solar energy. The cleaning mechanism can be driven to move by the driving mechanism to improve the flexibility of the cleaning mechanism and enable the cleaning mechanism to better clean the collector, thereby improving the cleaning effect.
[0033] Specifically, refer to Figure 1-3 The driving mechanism includes: a motor 3, two slide rails 4, a reciprocating screw 9 and a threaded sleeve 10; the motor 3 is installed at one end of the frame 2 away from the collector 1, and the two slide rails 4 are constructed to be arranged on the upper part of the frame 2 along the direction of the collector 1. The reciprocating screw 9 is connected to the output end of the motor 3 and is configured to be able to extend into one of the slide rails 4. The threaded sleeve 10 is installed on the surface of the reciprocating screw 9. Through this embodiment, the motor 3 can drive the reciprocating screw 9 to rotate after operation, and due to the characteristics of the reciprocating screw 9, the reciprocating screw 9 can drive the threaded sleeve 10 to reciprocate on its surface during the rotation process, so that the components connected to the threaded sleeve 10 can have a certain flexibility, avoiding the need to frequently operate related components.
[0034] Specifically, refer to Figure 1-3 The cleaning mechanism includes: a guide member 11, a sleeve 12 and a cleaning member 6; the guide member 11 is connected to another slide rail 4, the sleeve 12 is sleeved on the surface of the guide member 11, and the cleaning member 6 is installed between the sleeve 12 and the threaded sleeve 10. Through this implementation, the threaded sleeve 10 can drive the cleaning member 6 to move together during the horizontal reciprocating movement, and at this time the cleaning member 6 will drive the sleeve 12 on the other side to slide on the surface of the guide member 11 to perform a certain limit guide on the cleaning member 6 to avoid the reciprocating screw rod 9 driving the cleaning member 6 to rotate and affect its horizontal activity, and the length of the slide rail 4 is greater than the length of the heat collecting tube 5, so that the range of activity of the cleaning member 6 can be greater than the length of the heat collecting tube 5, so that the heat collecting tube 5 can be better cleaned.
[0035] Furthermore, the cleaning member 6 is constructed with a cleaning portion in contact with the surface of the heat collecting tube 5 along the direction of the heat collecting tube 5. Through this design, the cleaning member 6 can be a cleaning tool such as a brush or a cleaning cloth, so that the cleaning member 6 can clean the dust and impurities attached to the surface of the heat collecting tube 5 during the reciprocating movement, so as to improve the absorption and conversion effect of the collector.
[0036] Furthermore, the reflecting part 8 is located below the heat collecting tube 5, and the reflecting parts 8 are symmetrically distributed along the longitudinal center line of the heat collecting tube 5 in a group of two. Through this design, the sunlight energy can be irradiated on the front area of the heat collecting tube 5 as well as on the position of the reflecting part 8, so that under the action of the reflecting part 8, the light energy is reflected to the back area of the heat collecting tube 5 relative to the sunlight, and the symmetrically arranged reflecting parts 8 can better concentrate and reflect the solar energy. The reflecting part 8 can be a component such as a reflector to continue to reflect the sunlight to the back area of the heat collecting tube 5.
[0037] Furthermore, a detachable end cover 14 is installed at one end of the surface of the collector 1, and the end cover 14 is sealed with the collector 1. Through this design, the collector 1 can be opened or closed under the action of the end cover 14. After opening, the collector can be inspected and repaired, and after closing, the absorbed solar energy can be better stored to avoid dissipation.
[0038] Working principle: When using the utility model, first install the entire collector at the use position through the bracket, and then make the heat collecting tube 5 on its surface absorb the heat energy emitted by the sunlight and conduct it to the collector 1. After the heat collecting tube 5 absorbs the solar energy, the heat will be transferred to the heat transfer medium, and the heat transfer medium will flow to the place where the heat energy is needed with the absorbed heat. At this time, the reflective part 8 is arranged under the heat collecting tube 5, so that the sunlight energy can be irradiated on the front area of the heat collecting tube 5 and the position of the reflective part 8, so that the light energy is reflected to the back area of the heat collecting tube 5 relative to the sunlight under the action of the reflective part 8, and the reflective part 8 can adjust its reflection angle under the action of the rotating part 13. Adjustment is performed so that it can better reflect the solar energy to the heat collecting tube 5 for absorption, so as to improve the collector's absorption and utilization rate of solar energy and improve the use effect. Since dust and impurities are easily attached to the surface of the collector after long-term use, which affects the absorption effect of the heat collecting tube 5, the motor 3 can be started at this time so that the motor 3 can drive the reciprocating screw 9 to rotate, and the reciprocating screw 9 can drive the threaded sleeve 10 to move back and forth on its surface, so that the threaded sleeve 10 drives the cleaning part 6 to move, and the cleaning part 6 can contact the heat collecting tube 5, so that the cleaning part 6 can clean the dust and impurities attached to the surface of the heat collecting tube 5 during the reciprocating movement, so as to improve the absorption and conversion effect of the collector.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
