Description

Technical Field

[0001] The invention relates to the technical field of solar thermal utilization, in particular to a solar water heater integrating heat storage. Background Art

[0002] A solar water heater with integrated heat storage is a device that converts solar energy into thermal energy. It combines the functions of heat collection and heat storage. Its working principle is to absorb sunlight through the solar collector, convert light energy into heat energy, and heat the water or heat medium inside; then, the heat storage system stores the heated water for daily use;

[0003] In the process of solar thermal collection, a heat collecting tube heating method is adopted. The heat collecting tube absorbs the external solar heat, and then transfers the heat energy to the heat storage tank through water circulation. Finally, when hot water is needed, the hot water in the heat storage tank can be circulated in the required water supply direction; however, the heat transfer of the heat collecting tube adopts the water circulation method. In areas with large temperature differences between day and night, although the heat of the heat collecting tube accumulates quickly when the temperature is high during the day and is transferred to the heat storage tank quickly, when the temperature drops at night, the heat will also flow quickly from the high temperature area to the low temperature area with the water flow, thereby reducing the temperature of the water in the heat storage tank; in the prior art, insulation measures are adopted to reduce heat loss, but these insulation measures are bidirectional. Although they can block the diffusion of heat, they also reduce the efficiency of heat collection.

[0004] In order to solve the above problems, there are many solutions in the prior art, such as the solar organic heat carrier storage water heater with patent number CN102287933B, which uses an organic carrier as a medium to increase the heat storage temperature, and uses a heat transfer device to quickly transfer the heat to the heat storage tank. Although this method increases the temperature of the heat storage tank to ensure a continuous supply of heat, it does not solve the problem of heat diffusion outward when the external temperature drops.

[0005] Based on this, in order to solve the problem that in areas with large temperature differences between day and night, the heat in the solar water heater will be lost to the outside at low temperatures, thereby affecting the heat collection and storage efficiency, the present invention designs a solar water heater with integrated heat storage. Summary of the invention

[0006] The present invention provides a solar water heater with integrated heat storage. In order to solve the problem that in areas with large temperature differences between day and night, the heat in the solar water heater will be lost to the outside at low temperature through the heat collecting tube when the temperature drops suddenly, thereby affecting the heat collection and storage efficiency, the flow path between the heat collecting tube and the water storage tank is opened and closed according to the heat, so that the water in the heat collecting tube is circulated when the outside heat is higher than the set threshold, and the heat in the water storage tank is blocked when the outside heat is lower than the set threshold.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

When the temperature is lower than the set threshold, the regulating mechanism drives the rotating plate to rotate in the radial direction of the heat collecting tube; the set threshold here refers to a temperature higher than the normal water temperature, that is, a temperature that can transfer heat to the storage tank. The specific indication is not limited, but a suitable range can be selected; of course, the threshold here can also refer to a suitable temperature (normal temperature) of the heat body, that is, the water in the heat storage tank can be converted to normal temperature; through the regulating mechanism, the rotating plate is driven to rotate from a direction parallel to the tube mouth of the heat collecting tube to a direction perpendicular to the tube mouth of the heat collecting tube as the heat changes, and then when the heat gradually increases, the angle between the rotating plate and the plane of the tube mouth of the heat collecting tube can be gradually expanded, thereby increasing the amount of water circulation, thereby realizing heat transfer.

[0009] Preferably, the driving mechanism includes an open groove, an airbag, and a push piece, the open groove is opened on the side wall of the storage box, the airbag is installed in the storage box, the push piece is installed at the front end of the airbag, and the airbag is filled with hydrogen; the push piece can be connected to the internal slide groove of the storage box, and then the push piece will slide along the inner wall of the storage box without changing the longitudinal position.

[0010] Preferably, there are a plurality of rotating plates, and when the rotating plates are facing the axial direction of the heat collecting tubes, the ends of the rotating plates are fitted and sealed to each other, and can correspond one-to-one with the heat collecting tubes, thereby improving the efficiency of water circulation.

[0011] Preferably, the adjustment mechanism includes a driving block, an adjusting plate, a fixed shaft, a hinge plate, a hinge shaft and a connecting rod, the driving block is installed at the end of the push plate, the adjusting plate is installed at the corresponding heat collecting tube in the storage box, the fixed shaft is installed on the rotating plate and the inner wall of the adjusting plate, the hinge plate is installed on the rotating plate, one end of the hinge shaft is installed on the hinge plate, the connecting rod is installed on the other end of the hinge shaft and connects multiple hinge shafts, and the connecting rod is connected to the driving block; the adjusting plate can also realize the effect of heat conduction, and can accumulate the heat of the heat collecting tube on the side of the adjusting plate close to the heat collecting tube, thereby preheating the water flow at this location when the rotating plate is not rotating, thereby improving the efficiency of heat collection.

[0012] Preferably, the rotating plate is divided into an active end and a fitting end, and the active end and the fitting end are wedge-shaped surfaces that fit each other, thereby better fitting each other to form a sealing and isolating effect.

[0013] Preferably, a guide groove is provided on the rotating plate, and a metal sheet is installed in the guide groove, so that heat can be conducted and the distance of heat transfer can be reduced, so that heat is accumulated at the rotating plate.

[0014] Preferably, the metal sheet is streamlined, and when the rotating plate rotates to the axial direction of the heat collecting tube, the thickness of the metal sheet close to the heat collecting tube is greater than the thickness of the other end of the metal sheet, thereby utilizing the principle of fast thermal conductivity of small cross-sectional area under the premise of unit heat to achieve rapid heat transfer, and at the same time, it can also increase the flow rate of the water flow.

[0015] Preferably, a torsion spring is installed at the connection between the hinged plate and the fixed shaft. When the torsion spring is relaxed, the rotating plate is facing the heat collecting tube. Through the thermal effect of the airbag and the resetting of the torsion spring, the rotating plate can adaptively rotate when the external temperature changes, thereby opening and closing the circulation of the water flow and adjusting the size of the water flow, thereby improving the efficiency of heat collection and storage.

[0016] Preferably, the heat collecting tube is divided into an outer shell and an inner tube body, a vacuum layer is formed between the outer shell and the inner tube body, and the inner tube body is in contact with the inner wall of the heat conduction box, thereby reducing the heat loss rate and improving the thermal insulation performance.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A solar water heater with integrated heat storage proposed in the present invention drives a rotating plate to rotate from a direction parallel to the tube mouth of a heat collecting tube to a direction perpendicular to the tube mouth of the heat collecting tube through an adjusting mechanism as the heat changes. Then, when the heat gradually increases, the angle between the rotating plate and the plane of the tube mouth of the heat collecting tube can be gradually expanded, thereby increasing the amount of water circulation and realizing rapid heat transfer. When the external heat is low, the rotating plate rotates from a direction perpendicular to the tube mouth of the heat collecting tube to a direction parallel to the tube mouth of the heat collecting tube, thereby gradually reducing the angle between the rotating plate and the plane of the tube mouth of the heat collecting tube until the rotating plate is parallel to the tube mouth plane, thereby realizing water flow blocking. At this time, the water flow will not circulate, and the heat will accumulate inside the storage box, thereby improving the heat storage efficiency.

[0020] 2. The present invention proposes a solar water heater with integrated heat storage. When the rotating plate rotates to the vertical outlet of the heat collecting tube, the water in the heat collecting tube directly flows to the rear of the rotating plate. The shape of the rotating plate reduces the resistance to the water flow. At the same time, the heat is stored in the rotating plate through solid-state conduction and heat accumulation of the rotating plate, forming a heat barrier. When the external temperature drops suddenly, the heat in the storage box is protected by the heat at the rotating plate and will not flow to the heat collecting tube, thereby improving the heat collection and storage efficiency of the solar water heater body.

[0021] 3. The present invention proposes a solar water heater with integrated heat storage, in which an adjusting plate is used to install a rotating plate, and the adjusting plate is also used to block water circulation, so as to prevent the internal water flow from circulating when the rotating plate does not rotate, thereby failing to achieve the heat storage effect; the adjusting plate can also realize the function of heat conduction, and can accumulate the heat of the heat collecting tube on the side of the adjusting plate close to the heat collecting tube, thereby preheating the water flow at this location when the rotating plate does not rotate, thereby improving the heat collection efficiency; through the air bag thermal effect and the resetting of the torsion spring, the adaptive rotation of the rotating plate when the external temperature changes is realized, thereby opening and closing the water flow circulation, and adjusting the size of the water flow circulation, thereby improving the efficiency of heat collection and storage.

DETAILED DESCRIPTION

[0032] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1-3 As shown in Figure 5, a solar water heater with integrated heat storage provided by the present invention comprises a water heater body 1, a heat collecting tube 2, a storage box 3, a heat conducting box 4, a driving mechanism 5, an adjusting mechanism 6 and a rotating plate 7. The number of the heat collecting tubes 2 is plural, the heat collecting tubes 2 are installed at the front end of the water heater body 1, the storage box 3 is installed at the rear end of the water heater body 1, the heat conducting box 4 is installed on the outside of the storage box 3, the driving mechanism 5 is installed at the heat conducting box 4, the adjusting mechanism 6 and the rotating plate 7 are both installed in the storage box 3, the heat conducting box 4 is controlled by the temperature change of the outside and the heat collecting tube 2 to drive the driving mechanism 5, the driving mechanism 5 drives the rotating plate 7 to rotate through the adjusting mechanism 6, when the temperature is higher than the set threshold value, the adjusting mechanism 6 drives the rotating plate 7 to rotate in the axial direction of the heat collecting tube 2, when the temperature is lower than the set threshold value, the adjusting mechanism 6 drives the rotating plate 7 to rotate in the radial direction of the heat collecting tube 2.

[0034] The water heater body 1 includes a mounting frame and water pipes, etc. The internal water pipe arrangement can adopt existing technology. When the external heat is high, the heat will be transferred to the heat conduction box 4. The heat conduction box 4 can be provided with a receiving source of metal material, which can quickly sense the external heat. Compared with the heat collecting tube 2, the heat absorption at this place is faster and can be quickly controlled by the driving mechanism 5 to control the adjusting mechanism 6, thereby changing the direction of the rotating plate 7. Through the adjusting mechanism 6, the rotating plate 7 is driven to rotate from parallel to the pipe mouth of the heat collecting tube 2 to perpendicular to the heat collecting tube 2 as the heat changes. In the direction of the tube mouth of tube 2, when the heat gradually increases, the angle between the rotating plate 7 and the plane of the tube mouth of the heat collecting tube 2 can be gradually expanded, thereby increasing the amount of water circulation and realizing heat transfer; when the external heat is low, the rotating plate 7 rotates from perpendicular to the tube mouth of the heat collecting tube 2 to parallel to the tube mouth of the heat collecting tube 2, and the angle between the rotating plate 7 and the plane of the tube mouth of the heat collecting tube 2 is gradually reduced until the rotating plate 7 is parallel to the tube mouth plane, thereby realizing the blocking of water flow. At this time, the water flow will not circulate, and the heat will accumulate inside the storage box 3, thereby improving the heat storage efficiency.

[0035] like Figure 3 , 4 As shown, the driving mechanism 5 includes an open groove 51, an airbag 52, and a push piece 53. The open groove 51 is opened on the inner wall of the storage box 3. The open groove 51 can be connected to the interior, or a separate space can be opened to carry the driving mechanism 5 and the adjustment mechanism 6, thereby reducing the impact of scale on the work. The airbag 52 is installed in the storage box 3. The airbag 52 is a folding airbag 52. After inflation, it will expand and extend along a fixed trajectory, and will not diffuse around. The push piece 53 is installed at the front end of the airbag 52. The push piece 53 can be connected to the internal slide groove of the storage box 3, and then the push piece 53 will slide along the inner wall of the storage box 3 without changing the longitudinal position; the airbag 52 is filled with hydrogen.

[0036] Hydrogen has the fastest thermal reaction speed. After the airbag 52 conducts heat, the preheated hydrogen can expand quickly, thereby pushing the airbag 52. The airbag 52 will drive the push piece 53 to slide in the open groove 51. During the sliding process of the push piece 53, it will drive the adjustment mechanism 6 to change the angle of the rotating plate 7, thereby realizing the adjustment of the water flow transmission of the heat collecting tube 2 in the storage box 3.

[0037] There are multiple rotating plates 7, and when the rotating plates 7 are facing the axial direction of the heat collecting tube 2, the ends of the rotating plates 7 are sealed against each other; there are multiple rotating plates 7, which just correspond to the number of heat collecting tubes 2. In the figure, the number of heat collecting tubes 2 and rotating plates 7 is 15. The staff can adjust the number of rotating plates 7 and heat collecting tubes 2 according to actual needs. When the rotating plates 7 correspond to the heat collecting tubes 2, when the rotating plates 7 are rotated to be vertical to the pipe mouth of the heat collecting tube 2, the water in the heat collecting tube 2 directly flows through the rotating plates 7, thereby reducing the resistance to the water flow. At the same time, through the solid-state conduction and accumulated heat of the rotating plates 7, the heat is stored in the rotating plates 7 to form a heat barrier, and then when the external temperature drops sharply, the heat of the storage box 3 is protected by the heat at the rotating plates 7 and will not flow to the heat collecting tube 2, thereby improving the heat collection and storage efficiency of the solar water heater body 1.

[0038] like Figure 3-5As shown, the adjustment mechanism 6 includes a driving block 61, an adjustment plate 62, a fixed shaft 63, a hinge plate 64, a hinge shaft 65 and a connecting rod 66. The driving block 61 is installed at the end of the push plate 53. The installation here is only in contact, because under the action of the push plate 53, the driving block 61 needs to present an arc-shaped motion trajectory to achieve subsequent normal operation. Therefore, the position of the driving block 61 is not restricted here. The adjustment plate 62 is installed in the storage box 3 at the corresponding heat collecting pipe 2. The adjustment plate 62 is used to install the rotating plate 7. At the same time, the adjustment plate 62 is also used to block water circulation to prevent the internal water flow from circulating when the rotating plate 7 does not rotate, thereby failing to achieve the effect of heat storage. ; The adjusting plate 62 can also realize the function of heat conduction, and can accumulate the heat of the heat collecting tube 2 on the side of the adjusting plate 62 close to the heat collecting tube 2, and then preheat the water flow at this location when the rotating plate 7 is not rotating, thereby improving the efficiency of heat collection; the fixed shaft 63 is installed on the inner wall of the rotating plate 7 and the adjusting plate 62, the hinged plate 64 is installed on the rotating plate 7, one end of the hinged shaft 65 is installed on the hinged plate 64, the connecting rod 66 is installed on the other end of the hinged shaft 65, and multiple hinged shafts 65 are connected, the connecting rod 66 is connected to the driving block 61, the outer wall of the heat conduction box 4 is wrapped with a heat insulation layer, and the airbag 52, the push piece 53 and the driving block 61 are all made of heat conductive materials.

[0039] When the driving block 61 moves under the action of the push plate 53, the driving block 61 will drive the connecting rod 66 to move, and the connecting rod 66 will drive multiple hinged plates 64 to move through the hinge shaft 65. The hinged plate 64 will rotate around the fixed shaft 63 at this time, thereby driving the rotating plate 7 connected to the hinged plate 64 to rotate. The rotating plate 7 rotates around the fixed shaft 63 and is dislocated from each other, so that the water can flow out.

[0040] like Figure 6-7 As shown, a torsion spring 8 is installed at the connection between the hinge plate 64 and the fixed shaft 63 . When the torsion spring 8 is relaxed, the rotating plate 7 faces the heat collecting tube 2 .

[0041] When the temperature drops, the airbag 52 contracts, and the rotating plate 7 is reset under the action of the torsion spring 8, thereby driving the hinge plate 64 to reset. The hinge plate 64 will pull the connecting rod 66 through the hinge shaft 65, and the connecting rod 66 drives the driving block 61 to return to the initial position.

[0042] Through the thermal effect of the airbag 52 and the reset of the torsion spring 8, the adaptive rotation of the rotating plate 7 is realized when the external temperature changes, thereby opening and closing the circulation of the water flow, and adjusting the size of the water flow, thereby improving the efficiency of heat collection and storage.

[0043] like Figure 5 As shown, the rotating plate 7 is divided into an active end 71 and a fitting end 72, and the active end 71 and the fitting end 72 are wedge-shaped surfaces that match each other.

[0044] The active end 71 and the fitting end 72 can be set as an arcuate wedge surface or a straight wedge surface. The arcuate wedge surface can make the active end 71 and the fitting end 72 smoother during separation and splicing, while reducing the overflow of water after the two are fitted together, thereby improving the heat storage efficiency. The straight wedge surface structure is simple to process, and since the length of the rotating plate 7 is small, it can form a sealed fit along the inclined surface, and at the same time can guide the water circulation when the rotating plate 7 is perpendicular to the plane where the pipe mouth of the heat collecting pipe 2 is located, thereby improving the efficiency of water circulation and thereby improving the heat collection efficiency.

[0045] like Figure 8 As shown, a guide groove 73 is provided on the rotating plate 7, and a metal sheet 74 is installed in the guide groove 73. The metal sheet 74 is installed on a side close to the heat collecting tube 2, so that heat can be accumulated quickly, thereby improving the preheating effect at this location when the rotating plate 7 is not rotating. At the same time, when it is not rotating, the metal sheet 74 is in the first position and can evenly distribute the heat to various areas of the adjustment plate 62, thereby forming a heat isolation zone. On the one hand, the heat at the heat collecting tube 2 can be collected at the metal sheet 74 to prevent the heat in the storage box 3 from being transferred to the heat collecting tube 2. On the other hand, the heat of the rotating plate 7 can be absorbed when the heat in the storage box 3 is low. After the rotating plate 7 rotates, the metal sheet 74 becomes a heat conducting sheet, which can take advantage of the fast thermal conductivity of metal to accumulate the heat in the heat collecting tube 2 at the metal sheet 74, thereby reducing the heat flow path during the water circulation process, thereby improving the concentration and storage of heat.

[0046] The metal sheet 74 is streamlined. When the rotating plate 7 rotates to the axial direction of the heat collecting tube 2, the thickness of the metal sheet 74 close to the heat collecting tube 2 is greater than the thickness of the other end of the metal sheet 74. At this time, heat is concentrated at the metal sheet 74, and the water flow will flow along the metal sheet 74, and simultaneously drive the heat to flow along the streamlined metal sheet 74. At this time, on the basis of the unchanged water flow velocity, the cross-sectional area of ​​the metal sheet 74 is reduced, so the heat conduction speed is faster, and the heat can be quickly transferred to the storage box 3, thereby improving the heat storage efficiency.

[0047] like Figure 2 As shown, the heat collecting tube 2 is divided into an outer shell 21 and an inner tube body 22, and a vacuum layer is formed between the outer shell 21 and the inner tube body 22. The inner tube body 22 can contact the inner wall of the heat transfer box 4 through a medium, so that when the external sunlight cannot directly shine on the heat transfer box 4, the heat of the inner tube body 22 can make the rotating plate 7 rotate, and the vacuum layer can prevent the heat from dissipating and slow down the flow of heat. Therefore, the heat will be first transferred to the inner tube body 22, and then transferred to the heat transfer box 4 to make the rotating plate 7 rotate, and then the heat will be gradually stored in the storage box 3.

[0048] When the outside temperature is high, the water heater body 1 is located at a high place, and the sunlight shines on the heat collecting tube 2 and the heat conducting box 4. The water in the heat collecting tube 2 is heated and the temperature gradually rises. The temperature rise of the heat conducting box 4 will drive the regulating mechanism 6 to work through the driving mechanism 5, and the regulating mechanism 6 will drive the rotating plate 7 to rotate, so that the water in the heat collecting tube 2 can flow into the storage box 3, thereby realizing the heat transfer. Specifically, the heat of the heat conducting box 4 is transferred to the inside of the opening groove 51, driving the hydrogen in the air bag 52 to expand due to the heat, and then the air bag 52 stretches, driving the push piece 53 to move. During the movement of the push piece 53, The driving block 61 is driven to move, and the driving block 61 will drive the connecting rod 66 connected thereto to move. The connecting rod 66 is constrained by the hinge shaft 65, and then drives the hinge plate 64 to rotate around the fixed shaft 63. At this time, the hinge plate 64 will drive the rotating plate 7 to rotate around the fixed shaft 63. At this time, the active end 71 of the rotating plate 7 is separated from the fitting end 72. As the extension distance of the airbag 52 gradually increases, the distance that the push plate 53 pushes the driving block 61 is also gradually increasing, and then the rotating plate 7 gradually rotates from being parallel to the plane where the pipe mouth of the heat collecting tube 2 is located to being perpendicular to the plane where the pipe mouth of the heat collecting tube 2 is located, thereby gradually increasing the diameter of the water circulation.

[0049] When the outside temperature drops, the hydrogen in the airbag 52 shrinks when it encounters the cold, and the airbag 52 shrinks, thereby driving the push plate 53 to reset. At this time, the driving block 61 is not affected by the push plate 53, and under the action of the torsion spring 8 at the fixed shaft 63, the rotating plate 7 rotates and resets, and at the same time drives the hinge plate 64 and the hinge shaft 65 thereon to reset, and the connecting rod 66 also returns to the initial position with the hinge shaft 65, and then the rotating plate 7 blocks the gap of the adjustment plate 62, thereby forming an insulation against the heat in the storage box 3.

[0050] The basic principles and beneficial effects of the present invention are shown and described above. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements.
