Description

Technical Field

[0001] The utility model relates to the field of solar energy, in particular to a butterfly-shaped reflecting plate for a solar water heater. Background Art

[0002] Solar energy is an inexhaustible, clean and pollution-free energy source with huge development potential and application value. As an important field of solar energy application, solar water heaters have received widespread attention and application due to their environmental protection, energy saving and economic characteristics.

[0003] In the design of solar water heaters, how to improve the collection efficiency and conversion efficiency of solar energy is one of the key technologies. Traditional solar water heaters usually use flat-plate or vacuum tube collectors. Although these collectors can effectively collect solar energy, they still have certain limitations in terms of concentration effect and light energy conversion efficiency.

[0004] At present, there are no reflective plates specifically used for solar water heaters on the market. The main reason is that solar water heaters are fixed installations and are not powered by electricity. Installing reflectors underneath them is not very efficient. The low efficiency here is mainly because the angle of the sun is constantly changing, and the reflectors cannot change direction with the angle, thus failing to improve efficiency. However, there is a large amount of lighting space that can be used between the heat pipes of the solar water heater. How to increase the light and heat efficiency of the solar water heater is what we need to study.

[0005] In a tubular solar water heater, the sun can only shine on one side of the water heater's heat pipe according to the direction of the sun's radiation, and thus cannot shine on the lower part of the heat pipe, resulting in low sunlight utilization and reducing the use effect of the solar water heater. Therefore, a butterfly-shaped reflector for a solar water heater is proposed to solve the above problem. Utility Model Content

[0006] In order to make up for the above deficiencies, the utility model provides a butterfly-shaped reflector for a solar water heater, aiming to improve the problem in the prior art that "the sun usually can only shine on one side of the heat pipe and cannot shine on the lower part, thereby reducing the utilization rate of sunlight".

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 3 , Figure 4 The utility model provides an embodiment: a butterfly-shaped reflector for a solar water heater, comprising a body 1, the body 1 being a tubular solar water heater, the front surface of the body 1 being provided with a heat conducting tube 2 and being provided with a plurality of groups, the upper end of the outer wall of the heat conducting tube 2 being provided with a buckle 31 for providing support, the buckle 31 being used to fix the assembly between two solar heat conducting tubes 2, a reflective assembly being provided at the left bottom end of the buckle 31, the reflective assembly comprising a fixing member 4 for providing support, the fixing member 4 being arranged in an I-shape, the fixing member 4 being arranged in an I-shape and being able to cooperate with a triangular bar 45 to fix two groups of expansion plates 41, a triangular bar 45 being fixedly connected to the inner wall of the top right side of the fixing member 4 and being provided with two groups, the two groups of triangular bars 45 sliding into the two groups of triangular grooves 44 can clamp the two groups of expansion plates 41, and another group of triangular bars 45 being fixedly connected to the inner wall of the right bottom end of the fixing member 4.

[0033] Furthermore, the right inner wall of the fixing part 4 is plugged with an expansion plate 41 and two groups are provided. The expansion plate 41 can be set to a plate with a high thermal expansion coefficient, which will expand and extend after being heated, such as polyethylene material (expansion coefficient is as high as 1200*10^-7 / K) and some bubble-containing materials have a higher thermal expansion coefficient. Their thermal expansion effect is used to expand when heated to promote the movement of the reflector. Another group of expansion plates 41 at the bottom of the expansion plate 41 uses aluminum alloy profiles, or transparent materials such as quartz glass (thermal expansion coefficient is as low as 5*10^-7 / K). The expansion plate 41 is set to a high thermal expansion plate, and the other group of expansion plates 41 at the bottom is set to a low thermal expansion plate. Since the thermal expansion coefficient of the material is an inherent property, even in the cold winter and summer in the north, as long as the sun shines on the expansion plate 41, the deflection effect can also be achieved.

[0034] Furthermore, graphite 48 is arranged between the two groups of expansion plates 41. The graphite 48 is set to graphite powder, which can have a lubricating effect and can also conduct heat well. A triangular bar 45 is opened at the top of the expansion plate 41 and is inserted into the triangular groove 44 to limit the two groups of expansion plates 41 to be installed in the triangular groove 44. The triangular bar 45 is inserted into the inner wall of the triangular groove 44.

[0035] Reference Figure 1 - Figure 3A mounting assembly is provided at the top of the fixing member 4, and the mounting assembly includes a supporting block 3 for providing support. The bottom end of the supporting block 3 is fixedly connected with a fixing ridge 33 that can slide the fixing ridge 33 into the card slot 32 to connect the fixing member 4 to the supporting block 3. The two fixing ridges 33 can be stuck in the upper part of the fixing member 4, and the two fixing ridges 33 can maintain balance.

[0036] Reference Figure 2 - Figure 4 A conformal fixing groove 43 is provided at the top of the expansion plate 41 near the right side of the triangular groove 44. Through the conformal fixing groove 43, the conformal convex strip 46 on the fixing rib 42 can be stuck in the conformal fixing groove 43, so that other parts can be fixed to the fixing part 4. In terms of preventing falling off, weather-resistant glue can be used for adhesion. The inner wall of the conformal fixing groove 43 is plugged with a conformal convex strip 46. By setting the conformal convex strip 46, not only can it be fixed on the two groups of expansion plates 41, but also because of the circular contour, it can reduce wear and tear in the continuous deformation every day. The right side of the two groups of expansion plates 41 is clamped with a fixing rib 42 for moving the reflector 5. The fixing rib 42 is set to a circular contour. Setting it as a circular contour can reduce wear and tear in the continuous deformation every day. The conformal convex strip 46 is fixedly connected to the left side of the fixing rib 42 near the middle. A small hole 49 is provided on the front surface of the fixing rib 42. The small hole 49 can reduce weight and cost while ensuring strength.

[0037] Reference Figure 2 - Figure 4 A positioning groove 47 for fixing the reflector 5 is provided on the right side of the fixing rib 42, and the inner wall of the positioning groove 47 is plugged with the reflector 5. The reflector 5 is made of a thin and weather-resistant material. One solution is a single-layer structure, such as using mirror aluminum and adding a coating. The other is to use a composite material with two materials of high and low thermal expansion coefficients to paste, and apply a reflective coating on it, so that when it is heated and reflected, it will have a slight deformation, thereby forming a focusing effect and improving the reflection efficiency. The reflector 5 is set to be L-shaped, and the reflector 5 is set to be L-shaped and can be directly inserted into the positioning groove 47 on the fixing rib 42 for fixing. There are multiple groups of expansion plates 41, fixing ribs 42, reflectors 5, and triangular strips 45, and the multiple groups of expansion plates 41, fixing ribs 42, reflectors 5, and triangular strips 45 are symmetrically arranged with the center line of the fixing member 4 as the symmetry axis. Multiple groups of reflectors 5 can be set according to the number of heat pipes 2 to increase the reflection effect and the utilization rate of sunlight.

[0038] Reference Figure 1 - Figure 3The top of the fixing member 4 is provided with a slot 32 that allows the fixing ridge 33 to slide into the slot 32 to connect the support block 3 with the fixing member 4. The fixing ridge 33 is inserted into the inner wall of the slot 32, and the support block 3 is fixedly connected to the left side of the buckle 31. The slot 32, the buckle 31, and the fixing ridge 33 are provided in two groups, and the two groups of slots 32, buckles 31, and fixing ridges 33 are symmetrically arranged with the center line of the support block 3 as the symmetry axis. By providing multiple groups, the buckle 31 can be clamped on the two groups of heat pipes 2 to provide support. At the same time, the support block 3 and the buckle 31 can be provided in multiple groups, and the fixing ridge 33 can be clamped into the slot 32 at the same time, which can increase the support effect. The structure is simple and the mass production cost is low.

[0039] Working principle: When a solar water heating system needs to be installed in a place, the installer first installs the main body 1, and adjusts the width between the heat pipes 2 on each main body 1 according to the local sun angle. After the heat pipes 2 on the main body 1 are installed, first apply the heat pipe 2 to the fitting surface between the expansion plate 41 and another set of expansion plates 41, and then align the triangular grooves 44 on the expansion plate 41 and the other set of expansion plates 41 with the triangular strips 45, and then move the two sets of expansion plates 41 to slide into the right inner wall of the fixing member 4, and at the same time make the triangular strips 45 Slide into the triangular groove 44, and insert the reflector 5 into the positioning groove 47. At this time, move the fixing rib 42 so that the conformal convex strip 46 is aligned with the conformal fixing groove 43, and then insert the conformal convex strip 46 into the conformal fixing groove 43. At the same time, another group of conformal convex strips 46 on the bottom of the fixing rib 42 are inserted into another group of conformal fixing grooves 43, so that the expansion plate 41, graphite 48, another group of expansion plates 41 and fixing ribs 42 are installed on the fixing part 4, and the expansion plate 41, graphite 48, fixing ribs 42 and reflector 5 are also installed on the left side of the fixing part 4.

[0040] After the installation is completed, the fixed convex strip 33 is moved by moving the support block 3, so that the fixed convex strip 33 is aligned with the card slot 32 and inserted into the card slot 32, thereby connecting the fixing member 4 with the support block 3. Two groups of support blocks 3 can be installed above the fixing member 4. After the installation and connection are completed, the buckle 31 can be clamped on the heat pipe 2, and the other group of buckles 31 can be clamped on the other group of heat pipes 2 on the left side of the heat pipe 2 to complete the installation. When all parts are installed, the workers use weather-resistant glue to fix the seams. After solidification for a period of time, the installation is completed.
