[0030] First embodiment

[0031] See also Figure 1 to Figure 5The present invention provides a solar phase change energy storage heating system, comprising a base 101, a support frame 102, a solar module 103, a phase change energy storage module 104 and a heating module 105, wherein the support frame 102 is fixedly connected to the base 101 and is located on one side of the base 101, the solar module 103 comprises a solar panel, an adjustment frame and a power supply unit, the adjustment frame is arranged on the support frame 102, the solar panel is mounted on the adjustment frame, the power supply unit is connected to the solar panel, the phase change energy storage module 104 comprises a cavity 106, a first heating unit 107, a second heating unit 108 and a second heating unit 109. A thermal unit 108, an isolation plate 109 and a phase change energy storage unit 110, wherein the isolation plate 109 is arranged in the cavity 106, the first heating unit 107 and the second heating unit 108 are arranged on both sides of the isolation plate 109 and are connected to the power supply unit, the phase change energy storage unit 110 is arranged on one side of the first heating unit 107, and the heating component 105 includes a first water inlet pipe, a second water inlet pipe and a mixing box, the first water inlet pipe is connected to one side of the second heating unit 108 of the cavity 106 and is connected to the mixing box, and the second water inlet pipe is connected to the cold water supply end.

[0032] In this embodiment, the base 101 serves as the base of the entire system and provides a stable support structure. Fixedly connected to the base 101 is a support frame 102, which is located on one side of the base 101 and is used to carry and support the solar module 103. The solar module 103 is a key energy collection component of the system, which includes a solar panel, an adjustment frame and a power supply unit. Among them, the adjustment frame is installed on the support frame 102, allowing the angle of the solar panel to be adjusted according to the position of the sun, thereby optimizing the light absorption efficiency. The solar panel is responsible for converting light energy into electrical energy, while the power supply unit is connected to the solar panel, manages the generated electricity, and distributes it to other components of the system.

[0033] The cavity 106 of the phase change energy storage component 104 is a closed space, and an isolation plate 109 is provided inside to divide the space into two areas. Each area is respectively configured with a first heating unit 107 and a second heating unit 108, both of which are connected to the power supply unit to convert electrical energy into thermal energy and heat the phase change material. The phase change energy storage unit 110 is located on one side of the first heating unit 107, and realizes energy storage and release by absorbing or releasing latent heat. This energy storage method can provide a stable heat source when there is no sunlight, thereby improving the flexibility and efficiency of energy use. The heating component 105 consists of a first water inlet pipe, a second water inlet pipe and a mixing box. The first water inlet pipe is connected to one side of the second heating unit 108 in the cavity 106, and is responsible for transporting the heated water to the mixing box; while the second water inlet pipe is connected to the cold water supply end to provide users with the option of cold water input. The function of the mixing box is to mix hot water and cold water as needed to provide hot water of suitable temperature to the end user.

[0034] In summary, this solar phase change energy storage heating system not only realizes the effective collection of solar energy, but also solves the problem of intermittent energy supply through phase change energy storage technology, while ensuring the stability and reliability of heating.

[0035] The adjustment frame includes a support plate 111, a rotating rod 112, a first gear 113, a second gear 114 and a driving motor 115. The rotating rod 112 is rotatably arranged on the support frame 102, the support plate 111 is fixed to the rotating rod 112, the solar panel is arranged on the support plate 111, the first gear 113 is fixed to the rotating rod 112, the second gear 114 is meshed with the first gear 113, and the output end of the driving motor 115 is meshed with the second gear 114.

[0036] The support plate 111 is used as a bearing platform and is fixedly mounted on the rotating rod 112. The rotating rod 112 is flexibly arranged on the support frame 102 through a bearing or other rotating connection, allowing it to rotate freely around the axis. This arrangement allows the support plate 111 and the solar panel thereon to rotate together with the rotating rod 112, thereby changing its angle relative to the ground.

[0037] In order to accurately control the rotation of the rotating rod 112, a gear transmission system is used. Among them, the first gear 113 is firmly fixed to one end of the rotating rod 112, and the second gear 114 is meshed with it. The second gear 114 is directly connected to the output shaft of the driving motor 115 or indirectly connected through other forms of couplings. When the driving motor 115 is started, the torque it generates is transmitted to the first gear 113 through the second gear 114, thereby driving the rotating rod 112 to rotate. In this way, by controlling the direction and speed of the driving motor 115, the angle of the solar panel can be accurately adjusted so that it always maintains the best position facing the sun.

[0038] In addition, the system is also equipped with sensors and control systems for real-time monitoring of the sun's position and issuing instructions to the drive motor 115 to maintain the optimal tilt angle of the solar panel. Such an automated control system not only improves energy collection efficiency, but also reduces the need for manual intervention, ensuring long-term stable operation of the system.

[0039] The isolation plate 109 includes an isolation plate body 116, a control hydraulic cylinder 117 and a sealing plate 118. The isolation plate body 116 is slidably arranged in the cavity 106, the output end of the control hydraulic cylinder 117 is connected to the isolation plate body 116, and the sealing plate 118 is arranged around the isolation plate body 116.

[0040] The isolation plate body 116 is the core component of the entire structure, and is designed to be able to slide in the cavity 106 to adapt to different working conditions and requirements. The body is usually made of a material that is resistant to high temperatures, corrosion, and has good thermal conductivity, such as stainless steel or special alloys.

[0041] The control hydraulic cylinder 117 is the power source for driving the isolation plate body 116 to move, and its output end is directly connected to the isolation plate body 116. By accurately controlling the pressure and stroke of the hydraulic cylinder 117, the position of the isolation plate 109 can be adjusted to achieve the isolation and connection of the two sides of the cavity 106.

[0042] In order to ensure that the isolation plate 109 is in a closed state and minimize leakage, a sealing sheet 118 is provided.

[0043] The phase-change energy storage unit 110 includes an energy storage unit body 119 and a plurality of heat-conducting fins 120 . The plurality of heat-conducting fins 120 are disposed on the energy storage unit body 119 and close to the first heating unit 107 .

[0044] The energy storage unit body 119 is the core part of the phase change energy storage unit 110. It uses highly efficient phase change materials (PCMs) that can absorb or release a large amount of latent heat at a specific temperature, thereby achieving energy storage and release. In order to improve the efficiency of heat transfer, a plurality of heat-conducting fins 120 are carefully arranged on the energy storage unit body 119 and close to the first heating unit 107. These fins increase the surface area and promote the effective conduction of heat from the heating unit to the phase change material, making the energy storage process more rapid and uniform.

[0045] The phase change energy storage unit 110 further includes a circulation pump 121 , which is disposed in the cavity 106 .

[0046] In addition to the static energy storage function, the phase change energy storage unit 110 is also equipped with a circulation pump 121, which is located in the cavity 106. The function of the circulation pump 121 is to promote the flow of the internal fluid medium (such as water or other heat transfer liquid) to ensure that the heat can be evenly distributed throughout the energy storage unit. This design helps to avoid local overheating and improves the thermal response speed and stability of the entire system.

[0047] The phase change energy storage component 104 further includes a protective layer 122 , and the protective layer 122 is disposed outside the cavity 106 .

[0048] Considering the impact that the external environment may have on the cavity 106 and its internal components, the phase change energy storage component 104 further includes a protective layer 122, which is arranged on the outside of the cavity 106. This layer of protection not only provides physical protection to prevent accidental collision or mechanical damage, but more importantly, it has good thermal insulation performance, reducing the risk of heat loss to the outside.

[0049] The phase change energy storage unit 110 also includes a power generation detection unit 123, a heating control unit 124 and a mode switching unit 125. The power generation detection unit 123 is used to detect the power generation of the solar panel. The heating control unit 124 is used to calculate the heating power based on the power generation. The mode switching unit 125 allocates the heating power of the first heating unit 107 and the second heating unit 108 based on the heating power.

[0050] The power generation detection unit 123 is used to monitor the power generation of the solar panel in real time. This function provides basic data for subsequent heating control and ensures the maximum utilization of energy.

[0051] The heating control unit 124 calculates the appropriate heating power based on the data provided by the power generation detection unit 123. The unit dynamically adjusts the heating strategy according to the current power generation situation to keep the phase change energy storage unit 110 in an optimal working state.

[0052] The mode switching unit 125 automatically switches the heating power distribution between the first heating unit 107 and the second heating unit 108 according to the instruction of the heating control unit 124. This flexibility allows the system to flexibly adjust the heating mode according to actual needs, for example, giving priority to using solar energy for heating during the day, and activating a backup heating source at night or on cloudy days.

[0053] The heating component 105 also includes a temperature detection unit 126 and a valve control unit 127. The temperature detection unit 126 is used to detect temperature data in the mixing box, and the valve control unit 127 is used to control the valve openings on the first water inlet pipe and the second water inlet pipe based on the temperature data.

[0054] The temperature detection unit 126 is located inside the mixing box and is used to monitor the changes in the water temperature in the box in real time. This unit is usually composed of a high-precision temperature sensor that can quickly respond to temperature fluctuations and feed data back to the control system. By continuously monitoring the water temperature, it can be ensured that the final hot water temperature provided meets the user's set value to avoid overcooling or overheating.

[0055] The valve control unit 127 automatically adjusts the valve openings on the first water inlet pipe (hot water from the heating unit) and the second water inlet pipe (from the cold water supply end) based on the real-time temperature data provided by the temperature detection unit 126. This intelligent adjustment mechanism allows the system to dynamically balance the ratio of hot water and cold water according to actual needs, thereby accurately controlling the final output water temperature.

[0056] The mixing box includes a box body 128 and a liquid inlet pipe 129 . The liquid inlet pipe 129 is in communication with the first water inlet pipe and the second water inlet pipe. The box body 128 is in communication with the liquid inlet pipe 129 .

[0057] The tank 128 is the main structure of the mixing tank, and it provides enough volume to contain and mix hot water and cold water. The design of the tank 128 needs to consider factors such as corrosion resistance, heat preservation performance, and easy cleaning and maintenance, and is usually made of stainless steel or other materials suitable for high temperature environments.

[0058] The liquid inlet pipe 129 is connected to the first water inlet pipe and the second water inlet pipe to introduce hot water and cold water into the mixing box. The design of the liquid inlet pipe 129 is crucial to ensure that the two liquids are fully premixed before entering the mixing box, thereby affecting the uniformity and stability of the final output water temperature.

[0059] The liquid inlet pipe 129 includes a mixing cavity 130 , a mixing blade 131 and a liquid inlet pipe body 132 . The mixing cavity 130 is communicated with the liquid inlet pipe body 132 , and the mixing blade 131 is rotatably disposed in the mixing cavity 130 .

[0060] The mixing chamber 130 is a part of the liquid inlet pipe 129, and provides a space for preliminary mixing of hot water and cold water. Its shape and size are optimized to promote effective contact and mixing of the two liquids.

[0061] Mixing blades 131: Rotatably disposed in the mixing chamber 130, the design of the mixing blades 131 is similar to that of a stirrer, and can generate a vortex effect when water flows through, further enhancing the mixing efficiency. These blades can be fixed or can be rotating blades driven by a small motor, the latter of which can adjust the speed as needed to adapt to different flow conditions and mixing requirements.

[0062] The liquid inlet pipe body 132 connects the mixing chamber 130 and other pipes to guide the flow of liquid. The design of the liquid inlet pipe body 132 needs to take into account the fluid mechanics characteristics to ensure that the pressure loss is minimized while maintaining a good mixing effect.

[0063] In summary, the temperature detection unit 126 and the valve control unit 127 in the heating component 105 realize the intelligent control of the output water temperature, while the design of the mixing box and its liquid inlet pipe 129 ensures the optimal mixing of hot water and cold water. This combination not only improves the overall efficiency of the system, but also provides users with a stable and comfortable hot water supply experience. By integrating these advanced technologies and designs, the heating component 105 has become an indispensable and important part of the solar phase change energy storage heating system.

[0064] Second embodiment

[0065] See also Figure 6 The present invention also provides a solar energy phase change energy storage heating method, comprising:

[0066] S201 adjusts the solar panel to a corresponding position according to the incident angle of sunlight;

[0067] The angle of the solar panel is dynamically adjusted to ensure that it can always receive solar radiation at the optimal angle. Specifically, the system monitors the position of the sun in real time and calculates the ideal angle of incidence accordingly. Then, the drive motor 115 on the adjustment frame drives the rotating rod 112 to rotate, so that the solar panel can automatically adjust the angle as the sun moves. This process not only improves the energy collection efficiency of the solar panel, but also reduces the energy loss caused by fixed angles. In addition, different angle adjustment strategies can be preset according to seasonal changes and geographical locations to further improve the adaptability and flexibility of the system.

[0068] S202 performs functional heating on the first heating unit 107 and the second heating unit 108 through the power supply unit; the first heating unit 107 heats and stores energy in the phase change energy storage unit 110, and the second heating unit 108 heats the water source;

[0069] After ensuring that the solar panel is at the optimal angle, the power supply unit converts solar energy into electrical energy and distributes it to the first heating unit 107 and the second heating unit 108 for heating operations. Specifically, the first heating unit 107 heats and stores energy in the phase change energy storage unit 110. This part uses efficient phase change materials (PCM), which can absorb or release a large amount of latent heat within a specific temperature range, thereby achieving effective energy storage. During the heating process, heat is transferred to the phase change material, causing it to change from solid to liquid, completing the energy storage process. The second heating unit 108 is used to directly heat the water source. Unlike the first heating unit 107, the heating goal here is to quickly increase the water temperature so that hot water can be provided immediately. The second heating unit 108 is usually designed with a higher thermal power output to meet immediate needs.

[0070] S203 The water from the cold water supply end and the heated water source enter the mixing box through the first water inlet pipe and the second water inlet pipe to adjust the water source temperature;

[0071] When the first heating unit 107 and the second heating unit 108 complete the energy storage and instant heating tasks respectively, the next step is to accurately control the temperature of the hot water finally provided. The cold water from the cold water supply end and the hot water heated by the second heating unit 108 enter the mixing box through the first water inlet pipe and the second water inlet pipe respectively. An advanced temperature detection unit 126 and a valve control unit 127 are provided inside the mixing box. The former monitors the water temperature changes in real time, and the latter automatically adjusts the valve opening on the two water inlet pipes according to the set value to ensure that the output water temperature meets the user's needs. At the same time, the mixing chamber 130 and the rotating blade design in the mixing box promote the full mixing of the water flow and ensure the uniformity and stability of the temperature.

[0072] S204: When the heating power of the power supply unit is lower than a preset value, the phase change energy storage unit 110 releases heat to heat the water source.

[0073] Taking into account the problem of insufficient solar energy under weather conditions or at night, the system is also specially designed with an emergency heating mechanism. When the power generated by the power supply unit is insufficient to maintain normal heating (i.e., the heating power is lower than the preset value), the phase change energy storage unit 110 will start its heat release mode. At this time, the heat originally stored in the phase change material is released and transferred to the water source that needs to be heated through the heat exchanger. This design not only solves the problem of intermittent energy supply, but also provides additional safety protection to ensure that users can get a stable supply of hot water under any circumstances.

[0074] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
