Description

Solar collector assembly kit for solar panel, solar-thermal composite assembly including the same, and manufacturing method thereof

The description below relates to a collector assembly kit for a solar panel, a solar-thermal composite assembly comprising the same, and a method of manufacturing the same.

Due to the advancement of industrial society and the increase of population, much energy is required. The most widely used energy sources are fossil energy sources such as coal and petroleum natural gas, but these energy sources are limited and are gradually being depleted. This is urgent. On the contrary, unlike fossil energy sources such as coal and petroleum natural gas, solar heat is a clean energy source with no pollution, and is supplied almost unlimitedly. Therefore, it has been used for a long time as an energy source for industrial, heating or automobiles. In addition to steady research for commercialization is being made.

Currently, a solar collector and a solar module are used as a device using solar energy as an alternative energy source.

Flat solar collector and system is a new renewable energy system that obtains hot water and heating energy by directly heat-exchanging heat medium by using solar energy and is widely used because of its high efficiency and low initial investment cost.

On the other hand, photovoltaic modules and systems are devices that produce electrical energy by absorbing the light energy of sunlight and converting it into electrical energy without the environmental pollution by only one installation without the need for separate maintenance.

In the case of crystalline systems, only about 12 to 16% of the energy incident from the sun is used for power generation, so the solar energy utilization efficiency is low and the initial investment is very expensive. At this time, all the remaining energy is consumed as heat. At this time, due to the heat consumed to increase the temperature of the photovoltaic cell using a silicon material, etc., due to the characteristics of the cell, the electrical conversion efficiency is reduced when the electrical energy conversion by the temperature rise.

As such, the crystalline photovoltaic module generates heat in the process of generating power by receiving solar energy, and the generated heat degrades the electricity production performance of the photovoltaic module. It is necessary to remove the heat in order to promote this. Integrating a photovoltaic module into a building's envelope by integrating it into a building requires considerable effort to release the generated heat. In order to solve the heat dissipation difficulty of the crystalline solar power module and to improve the efficiency, a method by ventilation has been suggested, but heat dissipation has been limited.

1 to 8, the configuration and assembly process of the solar-thermal composite assembly according to an embodiment may be confirmed.

The solar-thermal composite assembly 1 according to an embodiment does not discharge heat generated in the electricity production process of the solar panel 11, but actively utilizes it as a heat source for heating air by using it as a hot water supply or heating purpose. It is intended to be used as.

To this end, the solar panel 11 can be coupled to a collector (collector assembly kit), through which it can absorb solar energy and produce electricity and hot water at the same time. A device having such a function can be called a photovoltaic / thermal (PV / T) composite system that secures a heat source generated from a photovoltaic system.

The solar-thermal composite assembly 1 according to an embodiment may include a solar panel 11 and a collector 12.

The solar panel 11 may be a panel having a rectangular shape that can absorb light energy and directly convert it into electrical energy. For example, the solar panel 11 may include a solar module 111 and an outer frame 112.

The solar module 111 may be an array of a plurality of solar cells. For example, the front surface of the solar module 111 may be disposed to be exposed to sunlight, and the collector 12 to be described later may be installed on the rear surface.

The outer frame 112 may be a rectangular frame shape member that surrounds and fixes the edge of the solar module 111. For example, the outer frame 112 may fix and support the collector 12 simultaneously with the solar module 111. For example, the outer frame 112 may have a shape extending in the rear direction of the solar module 111.

For example, the outer frame 112 may include an outer protrusion 1121 that protrudes in a direction facing each other at edge portions facing each other. For example, the outer protrusion 1121 may have a shape in which an edge end of the outer frame 112 protruding in the rear direction of the solar module 111 is bent inward of the solar module 111.

For example, the outer protrusion 1121 can fix the spar 124 for closely contacting the heat collecting plate 123 and the heat insulating material 125.

The collector 12 may be mounted on the rear surface of the solar panel 11, that is, the rear surface of the solar module 111 exposed to sunlight, and collect heat energy generated from the solar panel 11. . For example, the collector 12 may be an assembly kit installed on a commercially available solar panel 11 or a solar module 111.

For example, the heat collector 12 includes a heat collecting plate 123, a header 121, a heat insulator 125, a spar 124, a header cover 126, a header connector 129, a stopper protrusion 128, and a retainer 127. ) May be included.

The heat collecting plate 123 contacts the rear surface of the solar module 111, that is, the rear surface of the surface (front surface) where the solar cell of the solar module 111 is exposed to sunlight, It can absorb heat energy.

For example, the heat collecting plate 123 may be a plate or sheet-like member having an area similar to that of the solar module 111 and may be in surface contact with the rear surface of the solar panel 11.

For example, the heat collecting plate 123 may include a plurality of refrigerant pipes 1231 and curved portions 1232.

For example, the refrigerant pipe 1231 may be a passage passing through the heat collecting plate 123 along one direction in the heat collecting plate 123. For example, the plurality of coolant pipes 1231 may have a manifold type which is arranged in a straight line parallel to each other according to the width of the heat collecting plate 123 in a direction perpendicular to one direction. Accordingly, a flow path through which the refrigerant passes may be formed between both edges of the heat collecting plate 123 in one direction.

By forming the direction of the plurality of refrigerant pipes 1231 in a straight line, the direction of thermal deformation of the plurality of refrigerant pipes 1231 can be limited to only one direction, which is one direction of the heat deformation of the heat collecting plate 123. Can only be made possible to take account of.

For example, the cross section of the refrigerant pipe 1231 may have a circular or square shape. For example, when the cross section of the refrigerant pipe 1231 has a rectangular shape, compared with the case where the refrigerant pipe 1231 has a circular cross section, it is in contact with air in the space between the plurality of refrigerant pipes 1231 to exchange heat. This can be prevented from happening. In addition, it is easy to configure the contact between the adjacent refrigerant pipe 1231 in close contact, thereby improving the heat recovery efficiency.

For example, the material of the heat collecting plate 123 may be formed of a polymer having flexibility and corrosion resistance. For example, the material of the heat collecting plate 123 may include polyethylene having strong environmental resistance. As the heat collecting plate 123 is formed of a polymer material, it may have a long life through corrosion resistance. In addition, when the heat collecting plate 123 is manufactured through injection molding of a polymer, the manufacturing cost may be low.

For example, since the heat collecting plate 123 made of polymer material is advantageous in weight reduction, the burden on the load is small and can be used as a finishing material of the roof and the outer wall of the building. For example, the heat collecting plate 123 made of a polymer material can be folded or rolled up, and thus can be easily transported and installed, and thus a construction cost can be low.

The curved portion 1232 may be an edge portion of the portion of the heat collecting plate 123 to which the plurality of refrigerant pipes 1231 are connected to the header 121 to be described later.

The header 121 is provided at both edges of one direction of the heat collecting plate 123, that is, in the direction along the flow path of the refrigerant, that is, at the end of the refrigerant pipe 1231, and communicates with the plurality of refrigerant pipes 1231. Inflow and discharge of the refrigerant can be performed.

For example, the header 121 may be a hollow tube that is elongated in a direction perpendicular to the flow path of the refrigerant.

For example, the header 121 may include an inflow header 121a and a discharge header 121b.

The inflow header 121a may be installed at an edge of one side of the heat collecting plate 123. The inflow header 121a may receive the coolant from the outside to guide the coolant to the plurality of coolant pipes 1231 of the heat collecting plate 123. For example, the inflow header 121a may receive the refrigerant from one of the two ends, and may transfer the introduced refrigerant to the plurality of refrigerant pipes 1231 of the heat collecting plate 123.

The discharge header 121b may be installed at an edge of the other side of the heat collecting plate 123 facing the inflow header 121a. The discharge header 121b may receive the refrigerant passing through the plurality of refrigerant pipes 1231 and discharge the refrigerant to the outside.

For example, the inflow header 121a and the discharge header 121b are less than a portion where the heat collecting plate 123 is in contact with the rear surface of the solar module 111. The solar module 111 may be spaced apart from each other in a direction perpendicular to the solar module 111. Accordingly, the edge portion of the heat collecting plate 123 connected to each header 121, that is, the curved portion 1232 may be formed to be bent upward as shown in FIG. 12.

The heat insulating material 125 is installed on the opposite side of the solar panel 11 based on the heat collecting plate 123 and is installed along the area of the heat collecting plate 123 to prevent heat from being emitted from the heat collecting plate 123 to the outside. Can be. For example, the heat insulating material 125 may be pressed by the spar 124 and fixed to the heat collecting plate 123.

For example, the heat insulator 125 may be formed in plural numbers according to the width of the heat collecting plate 123. For example, the heat insulating material 125 may be formed by being separated into a plurality of sections according to the refrigerant flow direction in the heat collecting plate 123.

For example, the heat insulating material 125 may vary the thickness and the number of laminated sheets of the heat insulating material 125 according to the height of the outer frame 112 and the specification of the solar panel 11.

The spar 124 is a rod-shaped member connected between the opposing outer protrusions 1121 of the outer frame 112, and both ends thereof are fitted to the outer protrusions, whereby the collector 12 and the heat insulator 125 are formed. The light panel 11 may be pressed and fixed.

For example, the spar 124 may be installed in parallel with the longitudinal direction of the header 121, and may be configured in plural and installed in a plurality of sections according to the refrigerant flow path of the heat collecting plate 123.

For example, the spar 124 may include a pillar portion 1241, a pressing protrusion 1243, and a wing portion 1242.

Referring to FIG. 7A, the pillar part 1241 may directly contact and press the heat collecting plate 123. The pillar portion 1241 may form an outer shape of the spar 124 and extend in one direction, and may have a rectangular hollow cross section.

The pressing protrusion 1243 may be a protrusion protruding in a vertical direction from the upper surfaces of both ends of the pillar part 1241. For example, as shown in FIG. 5B, the pressing protrusion 1243 may be formed only on an upper side of the end portion of the pillar portion 1241, whereby the spar 124 may have an inner surface and a solar panel of the outer protrusion 1121. The heat insulating material 125 and the heat collecting plate 123 can be pressurized so that they may fit between them.

The wing part 1242 may be a member protruding in a vertical direction from both side surfaces of the pillar part 1241. As illustrated in FIG. 7A, the wing part 1242 may fix the heat insulating material 125 adjacent to both sides, and may closely contact the heat insulating material 125 to the solar panel 11.

Referring to FIG. 7B, a spar 124 of another embodiment is shown having pillar portions 1241 having a different shape than the pillar portion 1241 of 7a.

For example, the pillar portion 1241 of the spar 124 may provide a pressing force to the heat insulating material 125 only through the wing portion 1242 without directly contacting the heat collecting plate 123.

According to the above structure, when the photovoltaic module 111 and the heat collecting plate 123 are expanded by the heat generation of the solar module 111, the heat collecting plate 123 provides a free space for expanding, thereby collecting the heat collecting plate ( As the 123 expands, it can be prevented from being excessively pressurized by the spar 124 and damaged.

According to the spar 124, the heat insulating material 125 and the heat collecting plate 123 can be attached to the solar panel 11 without using a fastening member such as an adhesive or a bolt. This is a phenomenon in which the heat collecting plate 123 is detached from the solar panel 11 according to the difference in thermal strain of different materials when compared with the case of attaching the heat insulating material 125 and the heat collecting plate 123 using an adhesive. Can be prevented.

The header cover 126 is a cover member that surrounds the outside of the header 121, and when the heat collecting plate 123 is expanded or contracted according to the degree of heat generation of the photovoltaic module 111, the header 121 is exposed to the sun. Excessive deviation from the outer frame 112 of the light panel 11 can be prevented.

The header connector 129 may connect the headers 121 adjacent to each other when the two solar-thermal composite assemblies 1 are coupled to each other so that the refrigerants may communicate with each other.

The retainer 127 fixes the header cover 126 to the outer frame 112 of the solar panel 11 and at the same time the center of the header 121 exceeds the set distance as the heat collecting plate 123 shrinks. Can be prevented from moving.

The stopper protrusion 128 may protrude around the end of the header 121 to prevent the end of the header 121 from being inserted into the header cover 126.

In the solar-thermal composite assembly 1 according to an embodiment, since electricity and hot water can be simultaneously obtained from one module, space can be used more efficiently.

For example, in midsummer, the temperature of the surface of the solar panel 11 may rise up to 80 degrees. Each time the temperature of the solar panel 11 rises by 1 degree, the power generation efficiency of the solar panel may decrease by about 0.5%.

However, since the solar-thermal composite assembly 1 according to the embodiment absorbs thermal energy from the rear surface of the solar module 111, the solar module 111 is prevented from being overheated and power generation efficiency is constant. It can be maintained, and can improve the life of the solar module 111.

For example, the solar-thermal composite assembly 1 further increases energy conversion efficiency by about 52 with recovery of solar energy, with improved power generation efficiency compared to the case where only the solar panel 11 is used alone. Can be increased by more than%

It is a side view which shows.

9 to 13, in one embodiment, the configuration of the header cover 126 for limiting the deformation of the header 121 due to thermal expansion of the solar-thermal composite assembly 1 can be confirmed.

9 and 10, as the heat generation of the solar module 111, the heat collecting plate 123 may be inclined.

When the heat collecting plate 123 is viewed from above as shown in FIG. 9, since the temperature of the heat generated in the solar module 111 is largest in the center and decreases toward the edge, the degree of expansion of the heat collecting plate 123 is also increased. Depending on the part in contact with the optical module 111, it may be different.

Accordingly, the heat collecting plate 123 may have the largest expansion in the portion of the refrigerant pipe 1231 passing through the center portion, and close to the edge portion of the heat collecting plate 123 along the longitudinal direction of the header 121 at the center portion. In the portion of the refrigerant pipe 1231, the degree of expansion will be small.

According to the above structure, the degree of expansion of the plurality of refrigerant pipes 1231 of the heat collecting plate 123 may vary depending on the lengthwise direction of the header 121, as shown by the dotted line of FIG. 9, and other external conditions. In some cases, it may occur irregularly.

This, as shown in Figure 10, can move the position of the header 121 in the outward direction of the heat collecting plate 123 from the existing position, it is possible to make the center axis of the header 121 is distorted along the longitudinal direction, which is It may cause breakage of the header 121, interference between adjacent headers 121, or unstable flow of refrigerant.

In addition, as shown in FIG. 9, when the two solar-thermal composite assemblies 1 are assembled so that the respective headers 121 are connected to each other, the difference in local expansion of the heat collecting plate 123 is different from the header 121. In this connection, the coupling between the headers 121 may be unstable and may result in an internal force acting in the direction of releasing the coupling.

The header cover 126 according to an embodiment is formed in a structure surrounding the header 121 along the length direction of the header 121, thereby preventing the header 121 from being excessively separated from an existing position. can do.

For example, the header cover 126 may include a fixing portion 1261, a cover spar 1262, and a cover dome 1263.

The fixing part 1261 may be formed at one edge of the header cover 126 and may be fixed to the outer frame 112 of the solar panel. For example, a hole may be formed in a portion of the fixing portion 1261 that contacts the outer frame 112, and the outer frame 112 may be formed through a fastening element such as a screw, a bolt, or a rivet through the hole. It can be combined with

The cover spar 1262 may be formed at the other edge of the header cover 126, may be inserted into the outer frame 112, and a wing-shaped protrusion may be formed on the surface formed in the other direction, thereby collecting the heat collecting plate. The heat insulating material 125 disposed on the 123 may be fixed and pressurized.

For example, the cover spar 1242 has both ends along the longitudinal direction of the header 121 fitted to the inner surface of the outer protrusion 1121 of the outer frame 112, such as the spar 124, thereby providing an outer frame. The heat collecting plate 123 may be fixed to the solar module by pressing the heat collecting plate 123 against the outer frame 112.

The cover dome 1263 may be an arcuate member connected between the fixing portion 1261 and the cover spar 1262. For example, each end of the cover dome 1263 and the ends of the fixing part 1261 and the cover spar 1262 connected thereto may be formed in a bent annular shape engaged with each other to be firmly fixed.

For example, the inner diameter of the header cover 126 or the cover dome 1263 may be larger than the outer diameter of the header 121.

According to the header cover 126, at room temperature, the inner surface of the header cover 126, that is, the inner surface of the cover dome 1263 does not contact the header, and the solar panel 11 operates so that the heat collecting plate is operated. When the temperature of 123 is heated above a certain temperature, as the heat collecting plate 123 expands, the inner surface of the header cover 126 is opened after the header 121 contacts the inner surface of the header cover 126. Therefore, the curved portion 1232 may be deformed to rotate.

Accordingly, since the center of the header 121 is limited in the internal space of the header cover 126, the header 121 is separated out of the solar panel 11 or the central axis of the header 121 is moved. This excessive distortion can be prevented.

The U-shaped accommodating portion 1273 extends in the direction of being folded back from the base 1271, and may have a 'U' shaped curved portion. For example, as shown in FIG. 19, the U-shaped curved portion may be mounted to receive an end portion of the outer frame 112 or the outer protrusion 1121. Through this, the retainer 127 may be fixed to the outer frame 112 so as not to move in the vertical direction.

The first extension part 1276 may extend from one side of the U-shaped accommodating part 1273 and be disposed on an upper surface of the fixing part 1261.

The first fastening member 1277 may be a member that penetrates the first extension part 1276 and the fixing part 1261 and is pressed against the outer frame 112. For example, a portion of the first fastening member 1277 penetrating the first extension portion 1276 and the fixing portion 1261 may contact an edge portion protruding upward of the outer frame 112. For example, the first fastening member 1277 can include fastening elements such as screws, bolts, rivets, and the like.

The second extension part 1274 may extend from one side of the U-shaped accommodating part 1273 and be disposed on an upper surface of the cover spar 1262.
