Description

Technical Field

[0002] In high-altitude and frigid regions, where the climate is cold, the population is sparse, the location is remote, and electricity infrastructure is underdeveloped, residents still largely rely on traditional methods such as burning charcoal and cow dung for heating in winter. While the population density in these areas is often low and electricity demand is relatively low, the construction of traditional power infrastructure is extremely difficult and costly. These regions are characterized by high altitude, thin air, long hours of sunshine, and intense solar radiation. Photovoltaic power generation systems can convert solar energy into electricity, fully utilizing the abundant solar energy resources of these areas. Solar energy is a clean and renewable energy source, aligning with the requirements of sustainable development. While solar energy can power heaters, at night or when sunlight is insufficient, the photovoltaic modules cannot continue to supply power, requiring additional electricity for the heaters to operate. With increasing demands for quality of life and environmental awareness, the demand for heating in various scenarios is growing, especially in cold and power-deficient areas, where a thermal storage heater is urgently needed to meet diverse needs.

[0011] Optionally, the heat storage element is made of at least one of heat storage bricks, phase change materials, or heat storage solutions.

[0012] Optionally, when the heat storage component uses a heat storage brick, the heat storage brick includes a first brick body and a second brick body. The first brick body has a first groove, and the second brick body has a second groove. The first groove and the second groove are engaged to form a pipe hole, and the upper and lower ends of the pipe hole are through the heat storage brick.

[0019] The beneficial effects that this application can achieve are:

[0020] This application discloses a photovoltaic direct-drive thermal energy storage heating device. A heating element is installed inside the casing to heat the air. An air outlet is located at the upper end of the casing, and an air inlet is located at the lower end. When the heating element heats the gas in the containment cavity, the heated and expanding gas gradually moves upward, and hot air is introduced through the air outlet. Air from outside the casing enters the containment cavity through the air inlet at the lower end of the casing. The gas in the containment cavity remains in a state of movement through the air outlet and inlet. When the heat generated by the heater is needed, the air outlet is open to facilitate the heat being discharged to the external environment. When the heat generated by the heating element is not needed temporarily, the air outlet is closed, and the heat generated by the heating element is not immediately discharged from the air outlet; the heat in the containment cavity is absorbed and stored by the thermal energy storage element. The air outlet is then opened again when heat is needed. This allows the photovoltaic modules to supply power to the heating element during the day, while the heat storage element absorbs and stores the heat generated by the heating element, enabling the heat storage element to release heat at night, thus making reasonable use of the heat generated by the photovoltaic modules.

[0031] Example 1

[0032] Reference Figures 1-3 The first embodiment of this application provides a photovoltaic direct-drive thermal storage heating device, including: a housing 10 having a accommodating cavity; a heating element 20 disposed within the accommodating cavity, and a thermal storage element 30 disposed around the heating element 20; wherein, a first air layer 11 is provided between the thermal storage element 30 and the top wall of the housing 10, and a second air layer 12 communicating with the first air layer 11 is provided between the thermal storage element 30 and the bottom wall of the housing 10; the top wall of the housing 10 has an air outlet 40 communicating with the first air layer 11, and the bottom wall of the housing 10 has an air inlet communicating with the second air layer 12; the size of the air outlet 40 is adjustable so that the heat generated by the heating element 20 can be selectively discharged from the air outlet 40 or used to heat the thermal storage element 30.

[0033] In this embodiment, the heater is cubic in shape, with the shell 10 having six faces. The shell 10 can be made of insulating material. The heating element 20 is a direct current heating element, which is a component that can directly use direct current for heating. The working principle of the direct current heating element is based on the resistance heating effect generated when current passes through a conductor. When direct current passes through a conductor, the resistance inside the conductor causes electrical energy to be converted into heat energy, thereby raising the temperature of the conductor and achieving the heating effect. The heat storage element 30 can absorb and store heat.

[0034] The top wall of the housing 10 refers to the portion located at the upper vertical direction, and the bottom wall of the housing 10 refers to the portion located at the lower vertical direction.

[0035] When the air outlet 40 is open, the heat generated by the heat storage element 30 heats the air. When the air is heated, the average distance between its molecules increases, causing it to expand in volume. Although the mass remains the same, the increase in volume reduces the density of the air. Since the density of hot air is less than that of cold air, it experiences an upward buoyancy. The hot air moves along the air outlet 40, while the cold air in the environment surrounding the outer wall of the shell 10 enters the accommodating cavity through the air inlet on the shell 10. The air inside the accommodating cavity is in a state of flow. Most of the heat generated by the heating element 20 is discharged through the air from the air outlet 40, and a small portion of the heat is used to heat the heat storage element 30.

[0036] When the air outlet 40 is closed, the space inside the accommodating cavity is in a relatively sealed state. The heating element 20 heats the air inside the accommodating cavity. Since the hot air stays in the accommodating cavity for a long time, it heats the heat storage element 30, which stores most of the heat generated by the heating element 20. The size of the air outlet 40 is adjustable. By adjusting the size of the air outlet 40, the amount of hot air discharged from the air outlet 40 can be controlled. When the air outlet 40 is completely closed, the heat of the heat storage element 30 will not be discharged through the air outlet 40, thus maintaining the heat storage state of the heat storage element 30.

[0037] A support plate 70 is provided in the second air layer 12 to support the heat storage element 30. The support plate 70 divides the second air layer 12 into an upper air layer and a lower air layer. A through hole is provided in the support plate 70 along its thickness direction, connecting the upper and lower air layers. The air inlet on the housing 10 communicates with the lower air layer. The connection terminal of the heating element 20 passes through the support plate 70 and is located within the lower air layer. The connection terminal of the heating element 20 is made of heat-insulating material.

[0038] An independent power distribution space, separate from the accommodating cavity, can be provided on the outer wall of the housing 10. Electronic equipment related to electrical control can be placed within this power distribution space. The heating element 20 can be connected to the photovoltaic module. Under sufficient sunlight, the photovoltaic module can transmit the generated electrical energy to the heating element 20, causing it to heat the heat storage element 30. The heat storage element 30 stores energy, and when heat is needed, the outlet 40 is opened, allowing the heat storage element 30 to release the stored heat. When the outlet 40 is closed, the system's heat dissipation is low, relying solely on the surface of the housing for heat dissipation. When the outlet 40 is open, airflow increases the system's heat dissipation.

[0039] The housing 10 is embedded with a power switch. The cable is led out from the photovoltaic power generation module, connected to the power switch, and then connected to the heat insulation terminal. Finally, the heating element 20 is connected through the heat insulation terminal to connect the power supply.

[0040] A pot can be placed at the gas outlet 40 to heat water or cook food. Alternatively, the gas outlet 40 can be made relatively small, allowing users to sit around it for warmth. Due to the climate of high-altitude and cold regions, local residents often frequently brew beverages like oil tea and milk tea. Therefore, by placing a pot at the gas outlet and using the steam inside the container to maintain the temperature of these beverages, the system aligns with these habits, making efficient use of solar energy and reducing the need for additional electricity.

[0041] The heater is powered by photovoltaic DC. During the day, when there is sufficient sunlight, the photovoltaic modules generate DC power. After the power switch is turned on, the current is connected to the heating element 20 through the cable and terminal. After the heating element 20 is powered on, it starts heating. Part of the heat is dissipated through the air outlet 40 to provide heating, and part of the heat is stored in the heat storage element 30. After generating electricity and storing heat during the day, the heat storage element 30 stores a certain amount of heat for nighttime heating. The size of the air outlet 40 can be adjusted by controlling the regulating valve to change the heating temperature.

[0042] During the cold winter months, photovoltaic solar energy is used for heating. In summer and other non-heating seasons, the photovoltaic DC power generated by the heating element 20 can be used for other purposes, such as cooking and boiling water, fully utilizing the clean electricity generated by the photovoltaic power generation components. The heater in this embodiment can be powered on during the day when there is sufficient sunlight, storing excess heat in the heat storage element 30, and releasing it at night when there is no photovoltaic power. Therefore, it can rationally utilize heat without the need for batteries, allowing the stored heat to be used at night, greatly saving on battery and other energy storage costs. The heater in this embodiment has good heating effect, can quickly raise the temperature, has a simple structure for easy installation and use, is compact and does not occupy much space in the usage environment, is easy to transport and has low cost, operates reliably without electricity costs, has a long service life, and good economic benefits, making it suitable for widespread adoption.

[0043] Example 2

[0044] As an optional implementation, this embodiment provides a specific structure of the housing 10, including: at least one inner sidewall of the housing 10 is provided with a heat insulation layer 50.

[0045] Specifically, when the heater is cubic in shape, the inner wall of the shell 10 has six sides, and each of the six inner walls of the shell 10 can be provided with an insulation layer 50. All the insulation layers 50 enclose an insulation cavity, which reduces the rate of heat loss. The insulation layer 50 can be made of high-temperature resistant insulation materials such as aluminum silicate. It should be noted that both the air inlet and outlet 40 are connected to the insulation cavity. Alternatively, the insulation layer 50 can be provided on five of the inner walls of the shell 10, for example, only one of the four side walls can be left uninsulated. This increases the heat dissipation on the side wall without the insulation layer 50, raising the temperature of the outside air at that side wall, thus providing warmth to the user in that location.

[0046] Optionally, a sealing structure can be provided at the lower end of the housing 10. The sealing structure can block the air inlet, allowing the air inlet to be opened or closed or its size adjusted according to actual usage needs. A filter screen can also be installed at the air inlet to provide protection and prevent insects and other pests from entering the accommodating cavity through the air inlet.

[0047] Optionally, the heat storage element 30 is made of at least one of heat storage bricks, phase change materials or heat storage solutions.

[0048] Specifically, the heat storage brick is a magnesia-iron brick, a refractory material mainly composed of magnesium oxide (MgO) and iron oxide (FeO). It possesses excellent high-temperature performance and heat storage capacity, and is widely used in high-temperature industrial equipment, exhibiting high thermal stability and good heat storage performance. Its dense internal structure effectively stores heat. The heat storage brick has a high specific heat capacity, enabling it to absorb a large amount of heat during heating and release it slowly when needed. It is resistant to high temperatures and corrosion, has a long service life, and is suitable for long-term stable operation.

[0049] Phase change materials (PCMs) undergo solid-liquid or solid-solid phase transitions at specific temperatures, absorbing or releasing large amounts of heat. This phase change process is approximately isothermal, enabling highly efficient energy storage and release. PCMs have a much higher heat storage density than sensible heat storage materials, allowing them to store large amounts of heat in a relatively small volume. A wide variety of PCMs are available, including inorganic salts, paraffins, and fatty acids, allowing for the selection of appropriate materials based on application requirements.

[0050] Thermal storage solutions are typically composed of water or other solvents and one or more solutes, possessing high heat capacity and thermal conductivity. The thermal storage performance of the solution can be altered by adjusting the type and concentration of the solute. Thermal storage solutions can absorb a large amount of heat during heating and release it through heat exchangers or other equipment when needed. Their heating and heat release processes are relatively uniform and stable.

[0051] Optionally, when a heat storage solution is used as the heat storage medium, the heating element 20 also includes a housing for storing the heat storage solution. The housing is placed within a receiving cavity after sufficient heat storage solution has been added. The housing can be equipped with an outlet pipe and an inlet pipe for replenishing or replacing the heat storage solution. The heating part of the heating element 20 is located within the housing, and the heating element 20 heats the heat storage solution. A level gauge can also be installed within the housing to obtain the liquid level height. The housing can be made of a thermally conductive material, such as aluminum or ceramic. A venting channel can also be provided on the housing, connected to an outlet 40, allowing water vapor generated by the heat storage solution to be discharged through the outlet 40 to heat cookware placed at the outlet 40, according to actual usage requirements.

[0052] The heater housing 10 can be made into different shapes according to actual needs, such as TV cabinets, coffee tables, sideboards, etc., under the same principle. The air outlet 40 can also be set on the top or different facades to meet the needs of different scenarios.

[0053] like Figure 3As shown, the heat storage element 30 is a heat storage brick, which includes a first brick body and a second brick body. The first brick body has a first groove, and the second brick body has a second groove. The first brick body and the second brick body are fastened together, and the first groove and the second groove are fastened together to form a pipe hole. Both ends of the pipe hole penetrate the heat storage brick. The heating part of the heating element 20 is a cylindrical part that extends into the pipe hole. The heat storage brick may include two pipe holes, and the heating element 20 may be U-shaped, with its two arms extending into the two pipe holes respectively. It should be noted that when the heating element 20 is located inside the pipe hole, there is a gap between the outer wall of the heating element 20 and the inner wall of the pipe hole to ensure that the air inside the pipe hole can flow normally.

[0054] Optionally, the heating element 20 is connected to a photovoltaic module (not shown in the figure), which supplies power to the heating element 20. The photovoltaic module typically consists of multiple solar panels, which can be connected in series or parallel as needed to obtain the required voltage and current. The heating element 20 is connected to the photovoltaic module via an intelligent controller. The controller can monitor the output voltage and current of the photovoltaic module, as well as the operating status of the heating element 20, and adjust the power supplied to the heating element 20 according to a preset algorithm to achieve more efficient energy utilization and a more stable heating effect.

[0055] Optionally, the heating element 20 is connected to a storage battery (not shown in the figure), which powers the heating element 20. The photovoltaic module can also power the battery; when the electrical energy generated by the photovoltaic module exceeds the immediate needs of the heating element 20, the excess energy can be stored in the battery. In low light conditions or at night, the battery can provide power to the heating element 20, ensuring continuous system operation. A heating wire or induction cooker can also be installed on the housing 10, powered by the battery. The battery can also output AC / DC power for use in powering household appliances, lighting fixtures, and other electrical equipment.

[0056] Optionally, the cavity is provided with multiple heating zones, each heating zone is provided with at least one heating element 20, and the heating elements 20 of each heating zone are independent of each other.

[0057] Specifically, by setting multiple heating zones within the accommodating cavity, the operation of the corresponding heating zones can be controlled according to actual usage requirements. The boundaries between heating zones can be physical partitions, layers, or virtual control areas to ensure that the heating element 20 of each heating zone operates independently. The operating status of each heating zone can be flexibly adjusted according to different heating needs, improving heating efficiency and energy utilization efficiency.

[0058] Optionally, the housing 10 has at least one air outlet 40, and the housing 10 is provided with a bracket 60 located above the air outlet 40, the bracket 60 being used to support the heat-using equipment.

[0059] Specifically, when there is only one vent 40 on the housing 10, the vent 40 can be used for cooking or boiling water. When there are two vents 40 on the housing 10, one vent 40 can be used for cooking, and the other vent 40 can be used for boiling water at the same time.

[0060] A support 60 is installed above the air outlet 40. The support 60 has a cylindrical structure and covers the outer perimeter of the air outlet 40. The upper end of the support 60 has multiple grooves, and a raised structure is formed between adjacent grooves. The raised structure is used to support cookware, etc., while the grooves are used for air circulation. The heating device can be a cookware or other utensils.

[0061] Optionally, a guide tube (not shown in the figure) can be installed around the support 60. A gap is provided between the outer wall of the support 60 and the inner wall of the guide tube. The hot air in the accommodating cavity is led out from the air outlet 40 and enters the support 60. The hot air enters the gap from the groove on the support 60. The hot air moves from bottom to top in the gap, so that the horizontally blown hot air can move upward and increase the contact time between the hot air and the cookware.

[0062] Optionally, the upper end of the guide tube can be lower than the height of the support 60 to ensure that when the cookware is placed on the support 60, there is a certain distance between the upper end of the guide tube and the cookware, allowing hot air to contact the cookware as it escapes from the gap, thereby increasing the contact time between the hot air and the cookware. A sealing cap is provided at the upper end of the guide tube to seal the air outlet 40.

[0063] Optionally, a baffle (not shown in the figure) can be provided on the housing 10. The baffle is connected to a handle, which allows for the application of an external force to move the baffle back and forth. The baffle can be moved to the position of the air outlet 40 to adjust the size of the air outlet 40. The baffle can also be placed directly at the position of the air outlet 40 by means of removal and placement to block the air outlet 40.

[0064] Optionally, an opening (not shown in the figure) is provided on one side wall of the housing 10. The opening communicates with the receiving cavity. A movable door is hinged to the opening, allowing the opening to be opened and closed. When the opening is closed, the receiving cavity is relatively sealed, ensuring that the heat storage element 30 inside the cavity can store heat normally, and preventing hot air from escaping from the opening. When the opening is opened, the hot air inside the receiving cavity can escape through the opening, allowing for heating based on user needs, such as when users are sitting around the opening, thus adapting to user heating requirements and improving the functionality of the heater.

[0065] Optionally, air inlet and outlet channels can be installed at positions 40, with regulating valves installed within these channels to adjust the flow rate. The type of regulating valve can be selected based on specific requirements, such as manual, electric, or pneumatic valves. Different types of regulating valves offer varying levels of adjustment precision, response speed, and control methods; therefore, a suitable valve should be selected based on system requirements. By adjusting the valve opening, the flow rate in the air inlet and outlet channels can be precisely controlled to meet different system needs. The regulating valve can also be connected to other control systems (such as PLCs and DCSs) to achieve remote control and automated adjustment.

[0066] Optionally, the size of the air inlet and outlet 40 can be set according to actual usage needs. For example, the outlet 40 can be used only for heating, in which case the size of the outlet 40 can be smaller; the outlet 40 can also be used to heat cookware, in which case the size of the outlet 40 can be larger.

[0067] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
