Description

Technical Field

[0001] The utility model belongs to the field of solar heat exchange, and specifically relates to a heat exchange tube bracket for solar energy. Background Art

[0002] In a solar thermal utilization system, a heat exchange tube is one of the core components, which is responsible for converting solar energy into heat energy and transferring it to the working medium. Traditional solar heat exchange tubes are usually directly installed in the inner cylinder of the collector or fixed through simple supports. This installation method has some problems. For example, the heat exchange tube is prone to deformation due to thermal expansion and contraction, resulting in poor contact with the inner cylinder and affecting the heat exchange efficiency. In addition, the heat exchange tube may vibrate in the inner cylinder due to factors such as wind force or its own weight, resulting in wear or damage. And the fixed installation method makes it inconvenient to replace the heat exchange tube. Therefore, there has emerged a method of installing heat exchange tubes using brackets. For example, the utility model patent with the publication number CN221055270U provides an anti-freezing and power-free flat solar water heater, which includes a hot water storage tank and a solar flat collector. Two protection sleeves with multiple through holes on the peripheral walls are fixed at the upper part of the inner cavity of the hot water storage tank. A heat exchange bellows is arranged inside the protection sleeve. A heat collection and heat exchange tube is fixed at the lower part of the center of the inner cavity of the hot water storage tank. Two ends of the heat collection and heat exchange tube are respectively connected to the high-temperature interface and the low-temperature interface of the solar flat collector. The protection sleeve after passing through the hot water storage tank and the end of the heat exchange bellows are sealed through a conical silica gel sleeve. The operating medium in the heat exchange bellows is water. One end of the heat exchange bellows is connected to the cold water inlet pipe, and the other end is connected to the hot water outlet pipe. The operating medium in the heat collection and heat exchange tube is antifreeze.

[0003] This solution proposes to use a bracket to guide the installation of the heat exchange tube and is convenient for replacing the damaged heat exchange tube. However, the protection sleeve in this solution is arranged in a through manner in the inner cylinder, which is inconvenient for installation. During production, manual welding or purchasing special extra-long or extra-high welding equipment is required for processing and installation, resulting in low efficiency.

[0004] In view of this, this application is specifically proposed. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a heat exchange tube bracket for solar energy. The utility model is realized through the following technical solutions:

[0006] A heat exchange tube bracket for solar energy includes a support joint sealed and installed on the side cover of the inner cylinder. One end of the support joint extends towards the inside of the inner cylinder to form an installation part, and a support frame is installed on the installation part. The support frame is used for guiding the installation of the heat exchange tube.

[0007] Preferably, the support joint is a through-type tubular structure, and the other end of the support joint is arranged outside the inner cylinder.

[0008] Preferably, the end of the support joint arranged outside the inner cylinder is provided with an external thread, and an annular installation protrusion is arranged at the position where the support joint is closely attached to the outer side wall of the side cover.

[0009] Preferably, the diameter of the installation part gradually decreases towards one end of the inner cylinder, forming a frustum-shaped outer wall.

[0010] Preferably, two support joints are correspondingly arranged on the side covers on both sides of the inner cylinder, and the support frame is installed between the two support joints.

[0011] Preferably, at least two support joints are arranged on the side cover.

[0012] Preferably, the support frame is a tubular cage structure.

[0013] Preferably, the support frame is a pipe with a through middle, and a plurality of heat exchange parts are arranged on the outer wall of the pipe.

[0014] Preferably, two heat exchange parts are respectively arranged on the two lateral sides in the transverse direction of the pipe, and two heat exchange parts are also respectively arranged on the two lateral sides in the longitudinal direction of the pipe. Each heat exchange part includes a plurality of heat exchange holes arranged along the axis of the pipe, and the heat exchange holes arranged in the transverse and longitudinal directions of the pipe are staggered along the axis direction of the pipe.

[0015] Preferably, the heat exchange part is a plurality of heat exchange holes spirally arranged along the outer wall of the pipe.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By arranging support joints on the side covers of the inner cylinder and using these support joints to install the guiding support frame, during installation, the support joints can be first welded to the side covers by conventional automatic welding, and then the support frame can be installed on the support joints during assembly, which can ensure the stable installation of the heat exchange tubes and improve the installation efficiency.

[0018] 2. By setting the support joint as a through-type tubular structure, it is convenient for installation and maintenance, and at the same time, it is also convenient for connecting the inside and outside of the inner cylinder, simplifies the overall structure, and reduces the manufacturing cost.

[0019] 3. By setting the end of the installation part extending into the inner cylinder as a frustum shape that gradually becomes smaller, it can effectively guide the installation of the heat exchange tubes, avoid deviation during the installation process, thereby ensuring good contact between the heat exchange tubes and the inner cylinder, and improving the heat conduction efficiency.

[0027] The present utility model will be further described below with reference to the accompanying drawings.

[0028] As Figure 1 – Figure 5 shown, this embodiment provides a heat exchange tube support for solar energy, including a support joint 4 sealed and installed on the side cover 3 of the inner cylinder 2. One end of the support joint 4 extends towards the inside of the inner cylinder 2 to form an installation part 41. The installation part 41 is provided with a support frame 5, and the support frame 5 is used for guiding the installation of the heat exchange tube.

[0029] Specifically, the solar energy includes a support base 6, a heat collection component 7 and an outer cylinder 1. The inner cylinder 2 is installed in the outer cylinder 1. An exhaust hole 8 and a water pipe 9 are further provided on the side cover 3 of the inner cylinder 2 (this is a conventional technology in the field of solar energy and will not be elaborated here).

[0030] By providing a support joint 4 on the side cover 3 of the inner cylinder 2 and using this support joint to install and guide the support frame 5, during installation, the support joint 4 can be first welded to the side cover 3 by conventional automatic welding to achieve the sealed connection between the support joint 4 and the side cover 3. Then, during assembly, the support frame 5 can be installed on the support joint 4, which can ensure the stable installation of the heat exchange tube and improve the installation efficiency. After the support frame 5 is installed on the support joint 4, the side cover 3 is installed on the inner cylinder 2, and welding or other sealing operations are completed.

[0031] After the assembly is completed, the heat exchange tube is inserted into the support frame 5 along the support joint 4 to complete the installation of the heat exchange tube.

[0032] The support joint 4 is a through-type tubular structure, and the other end of the support joint 4 is arranged outside the inner cylinder 2. By setting the support joint 4 as a through-type tubular structure, it is convenient for installation and maintenance, and at the same time, it facilitates the connection of the inside and outside of the inner cylinder 2, simplifies the overall structure, and reduces the manufacturing cost.

[0033] Furthermore, an external thread 42 is provided at the end of the support joint 4 arranged outside the inner cylinder 2. It can achieve quick connection with other pipelines through threads, and can also seal the gap between the heat exchange tube and the support joint 4 through a rubber sleeve or the like. The external thread 42 can assist seals such as rubber sleeves to achieve a better sealing effect. It is not only easy to install, but also convenient to disassemble, and is easy to maintain and replace.

[0034] An annular mounting protrusion 43 is provided at the position where the support joint 4 is in close contact with the outer side wall of the side cover 3. The mounting protrusion 43 is in close contact with the side cover 3, which plays a limiting role during installation, and at the same time provides an annular welding part, which is convenient for welding the support joint 4 to the side cover 3 to achieve sealing.

[0035] Furthermore, the diameter of the end of the mounting part 41 facing the inner cylinder 2 gradually becomes smaller, forming a frustum-shaped outer wall. By setting the end of the mounting part 41 extending into the inner cylinder 2 as a gradually smaller frustum shape, it can effectively guide the installation of the support frame 5 and avoid deviation during the installation process, thereby ensuring the position between the heat exchange tube and the inner cylinder 2.

[0036] Further preferably, two support joints 4 are correspondingly arranged on the side covers 3 on both sides of the inner cylinder 2, and the support frame 5 is installed between the two support joints 4. By arranging support joints 4 on both sides of the inner cylinder 2, the support frame 5 can be stably supported at both ends, ensuring the stability of the heat exchange tube during use and reducing the risk of damage caused by uneven single-point stress.

[0037] At the same time, support joints 4 are arranged at both ends, so that the heat exchange tube arranged in the support frame 5 can be a U-shaped tube with one-sided inlet and outlet, or a straight tube with two-sided inlet and outlet for heat exchange or other heat exchange tubes with two-sided inlet and outlet, increasing the scope of application.

[0038] Even more preferably, at least two support joints 4 are provided on the side cover 3. That is, at least two groups or more groups of the matching structures of the support joints 4 and the support frame 5 are arranged in the inner cylinder 2, and the number and position of the support frame 5 can be flexibly adjusted according to actual needs, enhancing the adaptability and scalability of the system.

[0039] Preferably, the support frame 5 is a tubular cage structure (not shown in the figure). The support frame 5 can be a cage structure woven or welded by strip-shaped support bars. While meeting the support and guiding functions, it can not only provide sufficient support strength but also provide a sufficient flow-through area for the heat exchange water flow, improving the heat exchange efficiency.

[0040] The support frame 5 is a pipe with a through middle, and a plurality of heat exchange parts are opened on the outer wall of the pipe. The support frame 5 being a pipe with a through middle and having a plurality of heat exchange parts opened on the outer wall can increase the contact area between the water flow and the outer wall of the pipe, effectively improving the heat exchange efficiency.

[0041] Preferably, two heat exchange parts are respectively arranged on the two lateral sides of the pipe in the horizontal direction, and two heat exchange parts are also respectively arranged on the two lateral sides of the pipe in the vertical direction. Each heat exchange part includes a plurality of heat exchange holes 51 arranged along the axis of the pipe, and the heat exchange holes 51 arranged in the horizontal and vertical directions of the pipe are staggered along the axis direction of the pipe.

[0042] As Figure 3 shown in the pipe arranged on the outer side, by arranging the heat exchange holes 51 with staggered distribution in the horizontal and vertical directions of the pipe, the fluid flow path can be optimized, the heat can be more evenly distributed, and thus the heat exchange performance of the whole system can be improved. At the same time, the processing technologies such as directly punching holes or laser cutting holes on the pipe have low costs and are easy to process, which is beneficial to the popularization and use of the product.

[0043] Or, as Figure 6 shown in the pipe arranged on the inner side, the heat exchange part is a plurality of heat exchange holes 51 spirally arranged along the outer wall of the pipe. It can increase the turbulence degree of the water flow in the inner cylinder 2, improve the heat exchange efficiency, and at the same time help to prevent dirt deposition and extend the service life of the equipment.
