BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 1 It is a structure schematic view of a heating device provided by the embodiment of the utility model. DETAILED DESCRIPTION

[0017] The utility model will be explained further in detail below by combining with the drawings and the embodiment. It can be understood that the specific embodiment described here is only used for explaining the utility model, not limiting the utility model. In addition, it needs to be explained that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0018] Figure 1 It is a structure schematic view of a heating device provided by the embodiment of the utility model, referring to Figure 1 The heating device includes: solar water heater 10, coil pipe 20 and liquid container 30, solar water heater 10 communicates with coil pipe 20, coil pipe 20 is located in liquid container 30, solar water heater 10 is used to heat the heat conducting medium in coil pipe 20, to heat the liquid in liquid container 30.

[0019] Specifically, solar water heater 10 can heat the heat conducting medium such as water in heating coil pipe 20, because coil pipe 20 is located in liquid container 30, therefore, the heat conducting medium in coil pipe 20 can heat the liquid such as electrolyte of liquid battery in liquid container 30 after being heated by solar water heater 10, meet the heating demand of liquid battery. And, replacing the traditional electric heating mode with solar energy and water bath heating, can reduce the power consumption, through heating the heat conducting medium in the stainless steel coil pipe, indirectly heating the electrolyte, thereby reducing the use frequency of the electric heating equipment, reducing the production of scale, guaranteeing the heating efficiency.

[0020] The heating device provided by the embodiment includes: solar water heater, coil pipe and liquid container, solar water heater communicates with coil pipe, coil pipe is located in liquid container, solar water heater is used to heat the heat conducting medium in coil pipe, to heat the liquid in liquid container. The heating device provided by the embodiment, through heating the heat conducting medium in the stainless steel coil pipe, indirectly heating the electrolyte, thereby reducing the use frequency of the electric heating equipment, reducing the power consumption and the production of scale, guaranteeing the heating efficiency and the service life.

[0021] Optionally, the coil pipe 20 is a stainless steel coil pipe.

[0022] Specifically, stainless steel has strong corrosion resistance. Stainless steel contains elements such as chromium and nickel, and can form a dense chromium oxide protective film on the surface, so it has excellent chemical corrosion resistance. If the coil pipe contacts chemical substances such as acid, alkali, and salt, the stainless steel coil pipe can resist the corrosion of these substances and is not prone to rusting, thereby ensuring the normal operation and service life of the coil pipe. In water, especially water containing certain minerals or impurities, ordinary metals are prone to rusting, while stainless steel coil pipes have good water resistance and can effectively prevent dissolved oxygen, trace amounts of acid and alkali substances, and other substances in water from corroding the coil pipe, making them suitable for various water-based heating, refrigeration, or fluid conveying systems. Stainless steel has high strength and hardness and can withstand high pressure and external forces. During the use of the coil pipe, whether during installation or during long-term operation, the coil pipe may be subjected to various forces, such as fluid pressure, pipe weight, and stress caused by thermal expansion and contraction. Stainless steel coil pipes can withstand these stresses due to their high strength and are not prone to deformation or rupture. Stainless steel has good fatigue resistance and can maintain stable performance under long-term alternating stress, reducing the likelihood of fatigue cracks and extending the service life of the coil pipe, thereby reducing maintenance and replacement costs. The surface of stainless steel is very smooth and has low roughness, making it difficult for impurities to adhere and deposit on the pipe wall when the fluid flows through the coil pipe, reducing the likelihood of fouling. Stainless steel is a relatively stable material that does not release harmful substances into the transported fluid under normal use conditions, preventing contamination of the fluid and allowing stainless steel coil pipes to meet the high hygiene and safety requirements of various applications. The thermal conductivity of stainless steel is lower than that of copper but higher than that of plastic, with a moderate thermal conductivity coefficient. This allows stainless steel coil pipes to effectively transfer heat when used in heat exchange applications, while also controlling heat loss to some extent, improving heat exchange efficiency, and achieving energy-saving purposes. Stainless steel has a relatively small coefficient of thermal expansion, so the size of the coil pipe changes relatively little under large temperature changes, which helps to reduce stress and deformation caused by thermal expansion and contraction, ensuring the stability of the connection between the coil pipe and other components, reducing the probability of leaks and other failures, and improving the reliability of the heating device. Stainless steel has good corrosion resistance and wear resistance, so it does not need to be frequently treated for corrosion resistance or maintained on the surface. Regular simple cleaning can maintain the good performance and appearance of the stainless steel coil pipe, reducing maintenance costs and workload. Therefore, the coil pipe is preferably made of stainless steel.

[0023] Optionally, the heat-conducting medium is water, and the liquid is an electrolyte.

[0024] Specifically, water is suitable as a heat-conducting medium. For example, water has a large specific heat capacity of 4.2 x 10 3 Joule / (kilogram·Celsius), and can absorb or release a large amount of heat while its temperature changes relatively little. In the process of heat transfer, water can carry more heat, thereby more effectively achieving heat transfer and exchange, improving heat transfer efficiency, and making temperature control more stable. Among common liquids, water has relatively good heat conduction performance, with a thermal conductivity of about 0.6 W / (m·K). Good heat conduction performance enables water to quickly transfer heat from a heat source to an area that needs to dissipate heat, or transfer heat from a heating source to an object or space that is heated, reducing heat loss during transmission and improving the energy utilization efficiency of the entire heating device. Water is a non-toxic, odorless, and non-corrosive substance, which is very friendly to the human body and the environment. In the process of use, even if leakage occurs, it will not cause harm to the human body or pollution to the environment, greatly improving safety and reliability. Compared with organic heat-conducting media, water is non-flammable and non-explosive, so there is no need to worry about fire or explosion accidents caused by heat-conducting media during use of water as a heat-conducting medium, reducing the safety risk of the heating device and simplifying the safety protection measures and management requirements of the heating device. Water is extremely common and easy to obtain, and its price is relatively low compared to other heat-conducting media. Using water as a heat-conducting medium can significantly reduce costs and have a high cost performance. About two-thirds of the Earth's surface is covered with water, and water resources are relatively abundant. In most areas, enough water can be easily obtained to meet the needs of the heating device, without worrying about supply disruptions due to resource shortages, ensuring stable operation of the heating device. Under normal temperature and pressure conditions, water is chemically very stable and is not prone to chemical reactions with other substances, so water can be compatible with pipes, equipment, and other devices made of various materials, without causing corrosion or damage to the materials it contacts. Water has low viscosity and good flowability, can flow smoothly in pipes, reduces flow resistance, and reduces energy consumption during transportation, making the operation of the heating device more efficient. At the same time, good flowability also helps water to be evenly distributed in the coil, ensuring the uniformity of heat transfer.

[0025] Further, the electrolyte, as an electrically conductive medium for conducting ions between the positive and negative electrodes of the liquid battery, is an important component for the liquid battery to realize the charging and discharging process, and its performance directly affects the key performance indicators of the liquid battery, such as energy density, charging and discharging efficiency, cycle life and safety. The solvent is the main component of the electrolyte, which is used to dissolve the solute. For example, in lithium-ion batteries, common organic solvents include ethylene carbonate, dimethyl carbonate, and methyl ethyl carbonate. In aqueous batteries, water is the main solvent. The solute is the substance that dissolves in the solvent to form ion conduction. In lithium-ion batteries, common solutes include lithium salts such as lithium hexafluorophosphate and lithium tetrafluoroborate, which dissociate into lithium ions and corresponding anions in the solvent to provide carriers for the charging and discharging process of the battery. A small amount of additives in the electrolyte can improve the performance of the electrolyte. For example, in the electrolyte of lithium-ion batteries, a film-forming additive such as vinylene carbonate is often added, which can form a stable solid electrolyte interface film on the electrode surface during the first charging process of the battery, improving the cycle stability and safety of the battery. Electrolytes can be divided into aqueous electrolytes, non-aqueous electrolytes and ionic liquid electrolytes. Among them, aqueous electrolytes use water as the solvent, have high ionic conductivity, low cost, and environmental friendliness, and are commonly used in zinc-manganese batteries, nickel-hydrogen batteries, etc. However, the electrochemical window of water is relatively narrow, which limits the voltage and energy density of the battery. Non-aqueous electrolytes include organic solvent electrolytes and ionic liquid electrolytes. Organic solvent electrolytes are widely used in lithium-ion batteries and have a wide electrochemical window, enabling the battery to achieve high voltage and energy density, but they have safety problems such as flammability and volatility. Ionic liquid electrolytes have the advantages of non-volatility, non-flammability, good thermal stability and chemical stability, but the cost is high and they are still in the research and development stage. Electrolytes can conduct ions and participate in electrochemical reactions. During the charging and discharging process of the battery, the ions in the electrolyte migrate between the positive and negative electrodes, enabling the transfer of electric charge and completing the electrochemical reaction of the battery. Some components in the electrolyte may participate in the electrode reaction on the electrode surface, such as lithium ions in lithium-ion batteries, which are released from the positive electrode, migrate to the negative electrode through the electrolyte, and are embedded in the negative electrode material during charging. During discharging, lithium ions are released from the negative electrode and return to the positive electrode through the electrolyte. The electrolyte needs to have high ionic conductivity to ensure that ions can quickly migrate in the electrolyte, reduce the internal resistance of the battery, and improve the charging and discharging efficiency and power performance of the battery; wide electrochemical window: the electrolyte remains stable within a wide voltage range without redox reaction to ensure that the battery can work at a high voltage and improve the energy density of the battery; good chemical stability and thermal stability: the electrolyte should not react with the electrode material, battery shell, etc. during the use of the battery, and should maintain stable performance at different temperatures to prolong the service life of the battery; low viscosity: conducive to ion migration and diffusion, reducing the polarization of the battery and improving the charging and discharging performance of the battery.

[0026] Optionally, the heating device is a heating device for a flow battery.

[0027] Specifically, the heating device is used to heat the electrolyte in the flow battery to prevent the electrolyte from being too low in temperature and affecting the normal operation of the flow battery. Moreover, as a new type of electrochemical energy storage device, the flow battery dissolves active substances with different valence states in the electrolyte solution, and realizes charge transfer through the migration of ions in the solution, and is widely used in production and life. The energy and power of the flow battery can be independently adjusted: the energy of the flow battery is stored in the external electrolyte tank, and the power depends on the size and structure of the electrode stack. By increasing the amount of electrolyte, the energy storage capacity of the battery can be improved, and by increasing the electrode area of the electrode stack and optimizing the electrode structure, the output power of the battery can be improved. The independent adjustment characteristics of energy and power make the flow battery flexible in design and configuration according to different application scenarios and needs, better meeting the diversified needs of users. High energy density potential: New flow battery systems, such as polysulfide / bromine systems and zinc-bromine systems, have high theoretical energy density. With the continuous development of material science and battery technology, the energy density of the flow battery is continuously improving, gradually approaching or even exceeding traditional lead-acid batteries in some cases, making it more competitive in the energy storage field. The flow battery has high safety and strong stability. The flow battery usually uses aqueous solution as electrolyte, which is not flammable and explosive compared with the organic electrolyte used in traditional lithium-ion batteries, greatly reducing the safety risk of the battery during use. Even in the case of battery failure or external impact, it is not easy to cause fire, explosion and other serious safety accidents, improving the reliability and safety of the battery. Long cycle life: The positive and negative active materials of the flow battery are stored in different tanks. During charging and discharging, the chemical change of the active material mainly occurs in the solution, and the structure and performance of the electrode material are relatively stable and not easily damaged. Therefore, the flow battery generally has a long cycle life and can maintain high performance after multiple charging and discharging cycles. The number of cycles can reach more than 1000 times, and some can reach more than 5000 times, reducing long-term use costs. Environmentally friendly: The electrolyte and electrode materials used in the flow battery have relatively small environmental pollution during production, use and disposal. Some electrolytes of the flow battery system can be reused after simple treatment, and the electrode material can be recycled and reused, meeting the requirements of sustainable development and having good environmental benefits. Abundant resources: Some key materials of the flow battery, such as iron, zinc and vanadium, are relatively abundant on earth, which can ensure stable supply of raw materials and reduce the possibility of cost increase due to resource scarcity. Flexible design: The modular design of the flow battery makes it easy to expand or reduce according to different energy storage needs.By increasing or decreasing the number of stacks, electrolyte tank capacity, etc., it is easy to realize the construction of energy storage systems from tens of kilowatts to megawatts or even larger scales, suitable for various different scale application scenarios such as distributed energy power stations, microgrids, smart grids, etc. Good deep discharge performance: flow batteries can work stably within a wide range of discharge depth, and even in deep discharge conditions, they will not seriously affect the performance and life of the battery. This allows flow batteries to make more full use of their energy storage capacity, improving energy utilization efficiency and being suitable for applications that require frequent deep discharge, such as renewable energy storage regulation, grid peak shaving, etc.

[0028] Reference Figure 1 Optionally, the heating device further comprises a flow valve 40, which is located in the pipeline connecting the solar water heater 10 and the coil pipe 20.

[0029] Among them, the flow valve 10 is used for controlling fluid flow, and the flow valve 10 includes a throttling valve, a speed regulating valve, a flow dividing valve, a flow collecting valve and a flow dividing and collecting valve. Specifically, the throttling valve controls the fluid flow by changing the throttling section or the throttling length, and is connected in parallel with a one-way valve to form a one-way throttling valve, which is commonly used in quantitative pump hydraulic systems, and is connected with an overflow valve to form three throttling speed regulating systems, but cannot compensate for the speed instability caused by load changes, and is suitable for occasions with little load change or low speed stability requirements. The speed regulating valve is formed by connecting a constant difference pressure reducing valve and a throttling valve in series, which is a throttling valve with pressure compensation, can keep the pressure difference of the throttling valve inlet and outlet as a constant value when the load pressure changes, so that the flow through the throttling valve remains unchanged, thereby stabilizing the movement speed of the actuator. The flow dividing valve is an equal flow dividing valve or a synchronous valve that can make two actuators of the same oil source get equal flow, or a proportional flow dividing valve that can get proportional flow distribution, which can ensure that two or more oil cylinders can still be speed synchronized when bearing different loads. The flow collecting valve has the opposite function of the flow dividing valve, and can distribute the flow entering the flow collecting valve according to the proportion. The flow dividing and collecting valve has both the functions of the flow dividing valve and the flow collecting valve, also known as the synchronous valve, and is mainly applied to double-cylinder and multi-cylinder synchronous control hydraulic systems.

[0030] Further, the flow valve is usually composed of a manual regulating valve group and an automatic balance valve group. The regulating valve group is used to set the flow, and the automatic balance valve group is used to maintain the flow constant. When the manual regulating valve is adjusted to a certain position to determine the "set flow", the flow remains unchanged as long as the pressure difference before and after the manual regulating valve remains unchanged. When the flow changes and the pressure difference exceeds the allowed given value, the automatic regulating valve group will automatically adjust the opening to maintain the flow to the set flow. The flow valve has the characteristics of precise control, automatic adjustment, energy saving and high efficiency, wide application range, and good stability. Precise control: the flow valve can directly set the flow according to the design, and can control the flow within a certain range to the set value, which is not affected by factors such as system pressure fluctuation, so as to realize precise flow distribution and adjustment. Automatic adjustment: the flow valve, such as self-powered flow control valve and self-powered flow balance valve, can automatically adjust the valve opening according to the working condition change to maintain the flow stability without frequent manual intervention. Energy saving and high efficiency: by reasonably controlling the flow, unnecessary flow waste is avoided, the system energy utilization efficiency is improved, and the energy consumption is reduced. Wide application range: it can be used for various fluid media, including water, oil, gas, steam, etc., and is widely used in fluid conveying and control systems in different industries and fields. Good stability: high-precision sensors and intelligent controllers are used, which have high precision and stability, and can work stably for a long time under complex working conditions. The flow valve is widely used, in addition to being used in the heating device of the present embodiment, it is also used in heating and air conditioning systems to control the flow of hot water or cold water, ensure the uniform temperature of each room or area, improve the heating and air conditioning effect, and realize energy-saving operation. In oil and gas transportation and chemical production processes, the flow valve is used to accurately control the flow of various fluid media to ensure the safety, stability and efficiency of the production process. The flow valve is also used for flow control of fuel gas, combustion air, cooling water, etc. in heating furnaces, cooling furnaces and other equipment to improve production efficiency and product quality. In power plant boilers, generators and other equipment, the flow valve is used to control the flow of steam, fuel gas, cooling water, etc. to ensure the safety and stability of the power generation process. In hydraulic systems, the flow valve is used to control the flow of hydraulic oil to adjust the movement speed and output of the actuator (such as hydraulic cylinder, hydraulic motor) to achieve precise control of various mechanical actions. In urban water supply systems, the flow valve is an important part of the urban water supply network, which realizes automatic adjustment and monitoring of water quantity to ensure water supply safety and meet the water demand of urban residents and industries.

[0031] Optionally, the heating device further comprises a controller (not shown in the figure), which is in communication connection with the flow valve 40. Specifically, the controller is used to control the on-off of the flow valve 40 and the opening of the flow valve to control the flow size through the flow valve 40.

[0032] Reference Figure 1Optionally, the flow valve 40 is located outside the liquid container 30. In this way, the flow valve 40 can be prevented from being affected by the liquid in the liquid container 30 and from affecting the liquid.

[0033] With reference to Figure 1 Optionally, the heating device further comprises a box 50, and the coil 20 and the liquid container 30 are located inside the box 50.

[0034] Specifically, the relatively closed space inside the box 50 can reduce heat loss to the surrounding environment, so that heat exchange between the coil 20 and the liquid in the liquid container 30 is more sufficient and efficient. By placing the coil 20 and the liquid container 30 inside the box 50, the coil 20 and the liquid container 30 can be subjected to overall temperature control and monitoring, and temperature sensors and other devices can be arranged inside the box 50 as needed to provide real-time temperature feedback, so that the temperature of the fluid in the coil 20 and the temperature of the liquid in the liquid container 30 can be more accurately adjusted to ensure that the actual temperature requirements are met. The box 50 can provide physical protection for the coil 20 and the liquid container 30, preventing the coil and the liquid container from being mechanically damaged by external collisions, friction, and the like. The box can provide good protection, reducing the risk of the coil and / or the liquid container being broken, leaking, and the like due to accidents. By placing the coil 20 and the liquid container 30 inside the box 50, the coil 20 and the liquid container 30 can be isolated, preventing the liquid from directly contacting personnel or other equipment after leaking, thereby reducing the safety risk. Even if a leak occurs, the box 50 can collect the leaked liquid to some extent, facilitating subsequent processing and reducing pollution of the surrounding environment. By placing the coil 20 and the liquid container 30 inside the box 50, the layout of the entire heating device can be more compact, and space can be used more reasonably, especially in places where space is limited. In this way, the coil 20 and the liquid container 30 can be integrated together, making full use of space and avoiding the waste of space caused by the dispersion of the coil 20 and the liquid container 30. The box can shield the coil and the liquid container, making the appearance neat. The relatively concentrated coil 20 and liquid container 30 inside the box 50 facilitate regular inspection, maintenance, and repair by workers. When maintenance is required, the box 50 only needs to be opened to allow comprehensive inspection and operation of the internal components, eliminating the need to search for and disassemble scattered components in a complex space, thereby improving maintenance efficiency and reducing maintenance costs. The box 50 can effectively block dust, debris, and the like from entering, reducing pollution and blockage of the coil and the liquid container by dust, debris, and the like, helping to keep the coil 20 and the liquid container 30 clean and prolong their service life, while also ensuring normal operation of the heating device and reducing the frequency of faults caused by blockage of debris.

[0035] Optionally, the solar water heater is at least one.

[0036] Specifically, the solar water heater can be multiple, setting multiple solar water heaters can increase the output of hot water, multiple solar water heaters mean larger heat collection area and water storage capacity, can collect more solar energy and convert into heat energy, so as to provide more sufficient hot water supply, can meet the demand of using hot water, improve the supply capacity and guarantee degree of hot water. Improve energy collection efficiency: install multiple solar water heaters at different positions and angles, which can receive sunlight from different directions and angles, reduce the problem of insufficient heat collection caused by building shading, changes in sunlight angle and other factors. For example, in complex building structures, some areas may receive more sunlight in the morning, while other areas may receive more sunlight in the afternoon. By setting solar water heaters at different positions, we can make full use of sunlight resources throughout the day and improve the overall energy collection efficiency. Enhance stability: multiple solar water heaters can complement and back up each other, when one of them fails or cannot work normally due to special circumstances, the others can still provide hot water, ensuring the continuity and stability of hot water supply, reducing the risk of hot water supply interruption caused by single equipment failure. More accurate water temperature control: multiple solar water heaters can be connected in different ways to achieve more flexible water temperature adjustment. For example, some water heaters can be set to high-temperature heat collection mode for rapid water temperature rise, while others can be set to low-temperature heat collection mode for stable water temperature maintenance. In this way, we can adjust the hot water temperature more accurately according to actual needs. Adapt to different seasons and weather: in different seasons and weather conditions, the intensity of solar radiation and temperature change greatly. Multiple solar water heaters can be adjusted flexibly according to the changes of seasons and weather. In the summer with abundant sunlight, fewer water heaters can meet the hot water demand, while in the winter or on cloudy days, multiple water heaters can be used to ensure sufficient hot water supply and maintain appropriate water temperature. Energy saving and emission reduction: increasing the number of solar water heaters can make better use of solar energy, a clean energy, reducing dependence on traditional fossil fuels such as gas and electricity, thereby reducing carbon dioxide and other greenhouse gas emissions, which is of positive significance to environmental protection. With the increasing proportion of solar water heaters, the carbon footprint of the entire heating device will be significantly reduced, helping to achieve the goal of energy saving and emission reduction. Long-term cost savings: although the initial investment of multiple solar water heaters is relatively high, in the long run, it can save a lot of energy costs by reducing the consumption of other energy sources. Especially in the case of rising energy prices, cost savings will be more obvious, improving the economic efficiency and return on investment of the entire heating device. Facilitate device upgrade and expansion: for heating devices that need to be upgraded and expanded, pre-installing multiple solar water heater installation positions or reserving interfaces can facilitate the upgrade and expansion. Simply increase the number of solar water heaters or replace larger capacity devices can meet the new hot water demand without the need for large-scale modification of the entire heating device, reducing the cost and difficulty of heating device upgrade.Flexible adaptation to different needs: multiple solar water heaters can be individually configured according to different use scenarios and needs, and through reasonable pipeline connection and control, hot water supply for different purposes can be realized, improving flexibility and applicability.
