Description

Technical Field

[0001] This utility model relates to the field of air heating equipment, and in particular to a solar heating device and its heat collection components and heat collection tubes. Background Technology

[0002] The applicant disclosed a solar steam heating device in a prior Chinese utility model patent document with publication number CN221780696U, including a steam generating element and a solar collector assembly. The solar collector assembly includes multiple parallel-arranged collector tubes, and the steam generating element includes a heating pipe coaxially sleeved with the collector tubes. The heating pipe includes a water storage pipe for storing water. This method uses a single water storage pipe with multiple solar collector tubes mounted on it. However, current solar vacuum collector tubes are cylindrical. When multiple collector tubes are mounted on a single water storage pipe, in addition to filling the spaces between the collector tubes with insulation material, rain protection must also be considered. Furthermore, the sealing between the collector tubes is also an issue, which makes installation quite complicated and requires a significant amount of manpower for large-scale construction projects.

[0003] Meanwhile, a solar air heating device is disclosed in Chinese utility model patent document CN222103957U, including at least one air duct with an air inlet at one end and an air outlet at the other. Several heat collector tubes are fitted over the air duct, arranged sequentially at intervals along the duct's extension direction. Insulation material is filled between adjacent heat collector tubes, and heat-conducting fins for supporting the heat collector tubes are arranged on the outer surface of the air duct. The air duct is a single piece, eliminating the need to consider the sealing between adjacent heat collector tubes or their overall bending and folding resistance, thus offering high practicality. However, in actual use, it is still impossible to meet the rainproof requirements for the heat collector tubes, and the sealing between the heat collector tubes still requires considerable manual labor for assembly and installation.

Detailed Implementation

[0035] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown herein can generally be arranged and designed in various different configurations.

[0036] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. The terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are only used to distinguish different components. The terms "installed," "connected," and "linked" should be interpreted broadly, for example, they can refer to mechanical or electrical connections, or internal connections between two elements, and can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Specific embodiments of the solar heating device involved in this utility model are as follows: Figures 1 to 4 As shown, the solar heating device includes a heat collection component and a heating medium supply unit. The heating medium supply unit supplies the heat collection component with the corresponding working medium, such as air or water. Generally, if heating air to collect high-temperature air, the heating medium supply unit is a fan; if heating water to collect water vapor, the heating medium supply unit is a structure such as a water tank equipped with a water pump. Those skilled in the art can choose arbitrarily according to actual needs, without specific limitations.

[0039] The aforementioned heat collection assembly includes at least one heat exchange tube 1 for passing a heating medium. If the heating medium is air, the heat exchange tube 1 is a metal duct; if the heating medium is water, the heat exchange tube 1 is a water storage pipe. It also includes several heat collection tubes 3 sleeved outside the heat exchange tube 1. Each heat collection tube 3 is arranged sequentially end to end along the axial direction of the heat exchange tube 1. Heat exchange fins 2 for supporting each heat collection tube 3 are arranged on the outer surface of the heat exchange tube 1. The first end of the heat collection tube 3 has a first flared section 4 that gradually folds outward along its axial direction, so that when two adjacent heat collection tubes 3 are joined together, the end of the first flared section 4 of one heat collection tube 3 is placed on the outer side of the tail end of the adjacent heat collection tube 3.

[0040] Furthermore, the heat collection tube 3 has a second flared section 5 that gradually folds outward at the tail end. The port size of the first flared section 4 is larger than the port size of the second flared section 5. When the heat exchange tube extends upward at an incline, the first flared section 4 on the heat collection tube 3 is in a low position, and the second flared section 5 is in a high position.

[0041] In this embodiment, both the first flared section 4 and the second flared section 5 are circular flared mouth structures. Of course, in other embodiments, the flared sections can also adopt polygonal or elliptical flared mouth structures, without specific limitations.

[0042] The flared structure not only allows for the relative joining of the two parts, but also enables the first flared section 4 to guide external rainwater to flow out at an angle from its outer wall. The second flared section 5 prevents rainwater from accumulating on the body of the heat collector tube 3 to the tail end of the heat collector tube 3, allowing it to be discharged directly outward along the outer wall of the second flared section 5, thus avoiding rainwater accumulation and achieving effective rain protection.

[0043] Meanwhile, in order to ensure the heat insulation performance between two adjacent heat collection tubes 3 and to prevent heat loss, the mating surfaces of the first flared section 4 and the second flared section 5 are filled with heat insulation material 6.

[0044] Furthermore, in practical use, when too many heat collection tubes 3 are fitted onto a single heat exchange tube 1, the weight increases. Since existing heat exchange tubes 1 are generally fixed at both ends and suspended in the middle, to prevent excessive load on the center of the heat exchange tube 1, leading to deformation, bending, or even breakage, in this embodiment, a support rod 7 is installed below the middle of the heat exchange tube 1 for support. The support rod 7 is supported by a crossbeam 8. Because the heat collection tube 3 is located at the support point of the heat exchange tube 1, a first clearance groove 9 is provided on one side wall of the first flared section 4 to ensure support stability and assembly of the heat collection tube 3. The support rod 7 passes upward through the first clearance groove 9 and connects to the heat exchange tube 1. Simultaneously, to ensure smooth connection at the clearance groove, a second clearance groove 10 is provided on the second flared section 5, arranged to fit with the first clearance groove 9. The first clearance groove 9 and the second clearance groove 10 converge and surround the support rod 7.

[0045] The embodiment of the heat collection component involved in this utility model has the same structure as the heat collection component in the embodiment of the solar heating device described above, and will not be described in detail.

[0046] The embodiment of the heat collection tube involved in this utility model has the same structure as the heat collection tube in the embodiment of the solar heating device described above, and will not be described in detail.

[0047] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
