[0058] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0060] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0061] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0062] Unless otherwise stated, the term "multiple" means two or more.

[0063] As the background technology shows, in existing solar water heaters, the water tank is often placed above the collector. This layout design is mainly based on the principle of natural heat convection, that is, heat always flows from the high-temperature area to the low-temperature area.

[0064] Solar collectors, as components that capture solar radiation and convert it into heat energy, effectively absorb sunlight and convert it into heat energy. When a solar collector is heated, the temperature of its internal working fluid (such as water or a heat-conducting medium) rises, forming a hot fluid.

[0065] Because the water tank is located above the solar collector, according to the natural law that hot air rises and cold air sinks, the hot fluid will naturally rise into the water tank under the influence of gravity and temperature difference, exchanging heat with the water in the tank and thus transferring heat energy to the water to complete the heating process. This natural circulation method requires no additional power consumption, greatly improving heating efficiency.

[0066] However, the overall height of a solar water heater increases due to this layout of the tank and collector, making the selection of installation locations more stringent. Especially in urban environments, the greater height and footprint can affect the ease of installation and maintenance of solar water heaters.

[0067] Furthermore, solar water heaters located at higher elevations are more susceptible to severe weather conditions such as strong winds and snow accumulation. Wind loads can cause structural loosening or damage, while snow accumulation not only adds extra loads but can also obstruct the collectors, affecting heat collection efficiency.

[0068] In view of this, the present application provides a water heater, including a heat collection device and a water tank; by setting the water tank and the heat collection device to overlap at least partially in the horizontal direction, the height of the water heater is effectively reduced, which can improve the structural stability of the water heater and increase its resistance to wind and snow loads.

[0069] Furthermore, the water tank does not extend completely beyond the plane area where the heat collection device is located, reducing the horizontal footprint of the water heater and enabling it to adapt to diverse installation environments, thus improving the convenience of installation and maintenance.

[0070] Water heaters also include heat exchange components. The heat energy collected by the collector is transferred to the water tank via these components, heating the water inside. By using a heat exchange component as an intermediate medium between the water tank and the collector, the water tank is protected from direct contact with the high-temperature collector, extending its lifespan. Furthermore, this facilitates a modular design, improving the water heater's adaptability and making it easier to adapt to different installation environments.

[0071] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0072] Combination Figure 1As shown, this application embodiment provides a water heater, including a heat collection device 100 and a water tank 200. The heat collection device 100 is a component used to capture solar radiation and convert it into heat energy. After being heated, the heat collection device 100 can transfer the heat to the water tank 200 to heat the water in the water tank 200 to meet the user's need for hot water.

[0073] The water tank 200 and the heat collector 100 overlap at least partially in the horizontal direction. This horizontal overlap design of the water tank 200 and the heat collector 100 effectively reduces the height of the water heater.

[0074] Lowering the overall height of the water heater reduces its vertical space requirements, facilitating flexible installation and convenient maintenance. Simultaneously, a lower height also means a lower center of gravity, improving stability and enhancing resistance to wind and snow loads.

[0075] Furthermore, the water tank 200 does not extend completely beyond the plane area where the heat collection device 100 is located, improving the compactness of the water heater and reducing its horizontal footprint. This reduced footprint allows the water heater to adapt to diverse installation environments and space constraints, improving the ease of installation and maintenance.

[0076] In some embodiments, the water heater further includes a heat exchange component, which conducts heat with the heat collection device 100; the heat exchange component is connected to the water tank 200.

[0077] It is understandable that directly connecting the heat collection device 100 to the water tank 200 may cause the water tank 200 to be subjected to excessively high temperatures, affecting the durability of the water tank 200.

[0078] By setting up a heat exchange component as an intermediate medium between the water tank 200 and the heat collection device 100, temperature regulation can be performed during the heat transfer process to ensure that the water tank 200 operates within a safe temperature range and effectively transfer the heat collected by the heat collection device 100 to the water tank 200.

[0079] For example, the heat exchange components can be configured as detachable or standardized forms, making them easy to install, maintain, and replace, thereby simplifying the water heater's production process and installation procedures, reducing manufacturing and installation time, and improving efficiency. By implementing a modular design for the water heater, it is possible to adapt to diverse user needs and installation scenarios.

[0080] In some embodiments, the water tank 200 has a heat circulation inlet 210 and a heat circulation outlet 220, the liquid outlet 610 of the heat exchange component is connected to the heat circulation inlet 210, and the liquid inlet 620 of the heat exchange component is connected to the heat circulation outlet 220.

[0081] With this configuration, the water tank 200 and the heat exchange components form a closed thermal circulation loop, utilizing the fluid's flowability and thermal conductivity to ensure efficient heat transfer between the water tank 200 and the heat exchange components. Through this thermal circulation loop, the water in the water tank 200 can be continuously heated, maintaining a stable hot water supply.

[0082] Specifically, the water heater provided in this application embodiment reduces height and floor space while improving structural stability and resistance to wind and snow loads, thus achieving efficient, safe, and flexible application of the water heater.

[0083] Combination Figure 2 As shown, in some embodiments, the height of the liquid outlet 610 of the heat exchange component is higher than the height of the liquid inlet 620 of the heat exchange component.

[0084] Understandably, in fluid dynamics, when there is a temperature difference, the fluid with a higher temperature tends to flow to higher places, while the fluid with a lower temperature tends to flow to lower places.

[0085] By setting the liquid outlet 610 of the heat exchange component to be higher than the liquid inlet 620, the flow of fluid in the heat exchange component can be promoted by utilizing gravity and the natural flow characteristics of the fluid, reducing the dependence on external power devices such as pumps, reducing the energy consumption of the water heater, and improving the overall efficiency.

[0086] In practice, the heat exchange component exchanges heat with the heat collection device 100, and the liquid inside the heat exchange component is heated, causing its temperature to rise. The hotter liquid can flow towards the higher outlet end 610, forming a natural upward flow path within the heat exchange component.

[0087] In some embodiments, the height of the liquid outlet 610 of the heat exchange component is not higher than the height of the heat cycle inlet 210, and the height of the liquid inlet 620 of the heat exchange component is not higher than the height of the heat cycle outlet 220.

[0088] This configuration ensures that the fluid circulation path between the heat exchange components and the water tank 200 remains unobstructed, preventing fluid stagnation or backflow in the circulation path.

[0089] In practice, the hot liquid inside the heat exchange component reaches the outlet 610 and continues to flow upward, entering the water tank 200 through the heat circulation inlet 210 to heat the water in the water tank 200.

[0090] The original unheated liquid inside the water tank 200 has a low temperature. The low-temperature liquid will flow out of the water tank 200 through the heat circulation outlet 220 and continue to flow downwards. It will enter the heat exchange component from the liquid inlet end 620 and then exchange heat with the heat collection device 100.

[0091] In this way, a stable fluid circulation is achieved between the water tank 200 and the heat exchange components, ensuring the effective transfer of heat energy between the water tank 200 and the heat exchange components.

[0092] Specifically, the water heater provided in this application embodiment optimizes the flow path of the fluid by controlling the height of the liquid outlet 610 and the liquid inlet 620 of the heat exchange component and utilizing the height difference and fluid dynamic characteristics, so that the water heater can achieve efficient heat transfer and water heating without additional power.

[0093] In some embodiments, the heat exchange assembly includes a heat exchange element 600, which is connected to both the heat circulation inlet 210 and the heat circulation outlet 220.

[0094] Understandably, the heat exchanger 600, as the core component of the heat exchange assembly, can quickly and effectively transfer heat energy to the water in the water tank 200, ensuring a rapid increase and stabilization of the water temperature.

[0095] The heat exchanger 600 is directly connected to the heat cycle inlet 210 and outlet, which simplifies the fluid path, reduces potential flow resistance, and can form an efficient heat exchange path.

[0096] In some embodiments, the heat collection device 100 includes a heat collection pipe 130, which is connected to a heat exchanger 600, and the heat exchanger 600 conducts heat with the heat collection pipe 130.

[0097] By connecting the heat collection tube 130 to the heat exchanger 600, the heat collection tube 130 can effectively transfer the collected heat energy to the heat exchanger 600, and then to the water tank 200 through the heat exchanger 600. This ensures the high efficiency and continuity of heat energy collection and transfer.

[0098] For example, the heat collector tube 130 may be a pulsating heat pipe. The heat collector tube 130 is filled with a working fluid (such as water, ethanol, etc.).

[0099] When the solar collector tube 130 is heated, the working fluid inside absorbs heat and evaporates, forming steam. The steam flows inside the tube, and when it reaches a cooler area (near the heat exchanger 600), it condenses, releasing heat during this process. The condensed working fluid then flows back to the heating area to continue circulating after heating.

[0100] The heat exchanger 600 can absorb the heat released during the condensation process through contact with the heat collector tube 130 and transfer it to the water tank 200.

[0101] By designing the heat collector 130 as a pulsating heat pipe, the efficiency of heat absorption and transfer can be effectively improved, heat loss reduced, and the overall energy efficiency of the water heater enhanced. Furthermore, the pulsating heat pipe has a highly efficient phase change and circulation mechanism, making the heat collector 100 highly adaptable and capable of stable operation under different environmental conditions. Moreover, the pulsating heat pipe does not require additional mechanical moving parts, enabling the heat collector 100 to possess high reliability and a long service life.

[0102] Combination Figure 1 As shown, in some embodiments, the heat collection device 100 further includes a heat absorption plate 110; the heat absorption plate 110 has a first surface and a second surface disposed opposite to each other, the first surface of the heat absorption plate 110 is used to absorb heat energy, and the heat collection tube 130 is disposed on the second surface of the heat absorption plate 110.

[0103] Understandably, in the solar collector 100, the heat absorber 110 is responsible for absorbing solar radiation to generate heat energy.

[0104] For example, the heat absorber 110 may be made of a highly thermally conductive material and coated with a selective absorption coating to improve the absorption rate of solar radiation.

[0105] The absorber plate 110 has a first surface facing the sun, which is dedicated to absorbing solar radiation, and a second surface facing the mounting base 90, which is used to transfer heat energy to the collector tube 130. With this configuration, the absorber plate 110 can efficiently transfer the absorbed heat energy to the collector tube 130, reducing heat loss.

[0106] In practice, after the first surface absorbs solar energy, the heat energy can be transferred to the second surface through the thermal conductivity of the material. The heat collection tube 130 is set in close contact with the second surface, and the heat energy can be quickly transferred to the fluid inside the heat collection tube 130.

[0107] In some embodiments, the water tank 200 faces the second surface of the heat absorber plate 110.

[0108] By arranging the water tank 200 close to the second surface of the heat absorber plate 110, the path of heat energy from the heat absorber plate 110 to the water tank 200 can be shortened, thereby reducing heat loss and improving heating efficiency.

[0109] Furthermore, since the water tank 200 is close to the second surface of the heat absorption plate 110, the position of the water tank 200 is lowered, which helps to reduce the overall height of the water heater, improves the structural stability of the water heater, increases its resistance to wind and snow loads, and can adapt to diverse installation environments, improving the convenience of installation and maintenance.

[0110] Furthermore, the water tank 200 is located near the second surface of the heat absorber plate 110, that is, the water tank 200 is located below the heat collection device 100. This can prevent the water tank 200 from blocking the heat absorber plate 110, so that the heat absorber plate 110 can be fully exposed to sunlight and maximize the solar energy capture efficiency.

[0111] Furthermore, the second surface of the water tank 200 close to the heat absorber plate 110 means that at least part of the water tank 200 is shielded by the heat absorber plate 110. The heat absorber plate 110 can be used to protect the water tank 200 from the direct impact of the external environment, such as wind and snow, thus improving the overall durability of the water heater.

[0112] In some embodiments, the heat collection tube 130 includes a connecting section and a plurality of heat collection sections; in the width direction of the heat absorption plate 110, the plurality of heat collection sections are arranged in parallel and connected end to end in sequence to form a heat collection section group; the first end of the connecting section is connected to the liquid inlet of the heat collection section group, and the second end of the connecting section is connected to the liquid outlet of the heat collection section group.

[0113] By dividing the heat collection tube 130 into a connecting section and multiple heat collection sections, it is easier to adjust and optimize during manufacturing and installation. The heat collection tube 130 can be arranged more flexibly to adapt to different sizes and shapes of the heat absorption plate 110.

[0114] By arranging the collector sections in parallel, the surface area of ​​the absorber plate 110 can be fully utilized, increasing the solar energy capture efficiency. The collector sections connected end to end can form a continuous fluid path, ensuring uniform heating and efficient transfer of fluid within the collector tube 130.

[0115] The connecting section serves as the inlet and outlet of the collector section assembly, guiding and connecting the fluid flow. It ensures smooth fluid flow when entering and leaving the collector section assembly, allowing for efficient fluid circulation within the collector tube 130.

[0116] Combination Figure 2 As shown, in some embodiments, the heat collection tube 130 includes a surrounding section 131, which is arranged around the outside of the heat exchanger 600.

[0117] By placing the surrounding section 131 on the outside of the heat exchanger 600, the surface of the heat exchanger 600 can be effectively used for heat transfer without the need to insert the heat collection tube 130 into the heat exchanger 600.

[0118] By surrounding the heat collector tube 130 with the outside of the heat exchanger 600, interference with the structure of the heat exchanger 600 is reduced, and complex sealing treatment inside the heat exchanger 600 can be avoided, thereby reducing the risk of working fluid leakage.

[0119] Furthermore, the surrounding section 131 is positioned on the outside of the heat exchanger 600, supporting modular installation. This allows each component to be manufactured and assembled independently, simplifying the installation process. This modular design also facilitates subsequent maintenance and replacement, reducing maintenance costs and time.

[0120] In some embodiments, there are multiple surrounding segments 131, which are arranged sequentially at intervals in the extending direction of the heat exchanger 600.

[0121] Understandably, the design of multiple surrounding sections 131 allows heat to be transferred at multiple locations, reducing the heat load at a single location and improving heat utilization.

[0122] Multiple surrounding segments 131 are arranged at intervals, which also increases the contact area between the heat collection tube 130 and the heat exchanger 600. This design utilizes the basic principle of heat conduction, enhancing the heat transfer effect by increasing the contact area.

[0123] By increasing the contact area between the heat collector tube 130 and the heat exchanger 600, it is ensured that heat energy can be transferred quickly and evenly from the heat collector tube 130 to the heat exchanger 600.

[0124] In some embodiments, the heat collection tube 130 further includes a transition section 132, which connects two adjacent surrounding sections 131.

[0125] The transition section 132 serves as a bridge connecting adjacent surrounding sections 131, providing a channel for the flow of working fluid between adjacent surrounding sections 131. This ensures the smooth flow of working fluid within the heat collection tube 130 and improves the circulation efficiency of the working fluid.

[0126] It should be noted that a portion of the pipe section of a surrounding section 131 and two transition sections 132 connected to the surrounding section 131 can form a heat collection section. That is, each heat collection section is provided with a surrounding section 131.

[0127] The steam formed by the working fluid inside the heat collection section when heated can quickly flow to the vicinity of the heat exchanger 600 for condensation, so as to transfer heat to the heat exchanger 600.

[0128] This configuration reduces the steam flow path, which helps to achieve efficient heat exchange between the collector tube 130 and the heat exchanger 600.

[0129] Combination Figure 3 As shown, in some embodiments, there are multiple surrounding segments 131, which are connected sequentially in the extending direction of the heat exchanger 600.

[0130] By setting multiple surrounding sections 131, the heat collection tube 130 can contact the heat exchange element 600 over a larger area, thereby increasing the total area for heat transfer and helping to improve the efficiency of heat collection and transfer, enabling the water heater to utilize solar energy more effectively.

[0131] The sequentially connected surrounding sections 131 enhance the modularity of the heat collector tube 130, simplifying its assembly process and making manufacturing and installation more convenient. Simultaneously, this modular design facilitates the assembly of the heat collector tube 130 with the heat exchanger 600, improving overall installation efficiency and maintenance convenience.

[0132] Combination Figure 4 As shown, in some embodiments, the heat collection tube 130 includes a plurality of extensions 133 disposed inside the heat exchanger 600.

[0133] The heat exchanger 600 has a receiving cavity 601, which can be used to contain refrigerant. The extension section 133 is disposed in the receiving cavity 601.

[0134] Understandably, placing the extension section 133 inside the receiving cavity 601 allows it to come into more direct contact with the refrigerant in the receiving cavity 601, thereby improving the efficiency of heat transfer.

[0135] By placing the extension section 133 within the receiving cavity 601, the advantage of direct contact is utilized, shortening the heat transfer path, reducing heat loss, and improving transfer efficiency, thereby enhancing the efficiency of heat transfer.

[0136] In some embodiments, a plurality of extension segments 133 are arranged sequentially at intervals in the extension direction of the heat exchanger 600.

[0137] Understandably, the design of multiple extensions 133 allows heat to be transferred at multiple locations, reducing the heat load at a single location and improving heat utilization.

[0138] Multiple extension sections 133 are arranged at intervals, increasing the contact area between the heat collection tube 130 and the heat exchanger 600. This design utilizes the basic principle of heat conduction, enhancing heat transfer by increasing the contact area.

[0139] By increasing the contact area between the heat collector tube 130 and the heat exchanger 600, it is ensured that heat energy can be transferred quickly and evenly from the heat collector tube 130 to the heat exchanger 600.

[0140] For example, the extension section 133 can be in the shape of a single-layer spiral, a multi-layer spiral, a circle, or a serpentine shape. The extension section 133 can also be bent toward the liquid inlet end 620 or the liquid outlet end 610 of the heat exchanger 600.

[0141] Specifically, the longer the extension section 133 is, the larger the contact area between the extension section 133 and the refrigerant in the receiving cavity 601 of the heat exchanger 600, and the better the heat transfer effect.

[0142] In some embodiments, the heat collection tube 130 further includes a plurality of transition sections 132, which connect two adjacent extension sections 133.

[0143] The transition section 132 serves as a bridge connecting adjacent extension sections 133, providing a channel for fluid flow between adjacent extension sections 133, ensuring smooth fluid flow within the heat collection tube 130, and improving fluid circulation efficiency.

[0144] It should be noted that a section of pipe of an extension 133 and a portion of the pipe of two transition sections 132 connected to the extension 133 can form a heat collection section. That is, each heat collection section is provided with an extension 133.

[0145] With this configuration, the steam formed by the working fluid inside each heat collector section when heated can quickly flow to the vicinity of the heat exchanger 600 and condense, so as to transfer heat to the heat exchanger 600. This reduces the flow path of the steam and helps to achieve efficient heat exchange between the heat collector tube 130 and the heat exchanger 600.

[0146] Combination Figure 5 As shown, in some embodiments, the heat collection tube 130 includes a plurality of extension segments 133, which are connected sequentially in the extension direction of the heat exchanger 600.

[0147] The design of multiple extension sections 133 allows the heat collection tube 130 to flexibly adapt to different heat exchanger 600 structures, increasing the contact area with the heat exchanger 600 and thus improving the efficiency of heat transfer.

[0148] Furthermore, the sequentially connected extension sections 133 enhance the modularity of the heat collector tube 130, simplifying its assembly process and making manufacturing and installation more convenient. This modular design also facilitates the assembly of the heat collector tube 130 with the heat exchanger 600.

[0149] Combination Figure 1 As shown, in some embodiments, the top height of the water tank 200 is lower than the top height of the heat collection device 100.

[0150] By setting the top of the water tank 200 lower than the top of the heat collector 100, the water tank 200 will not completely exceed the plane area where the heat collector 100 is located, which helps to reduce the horizontal footprint of the water heater and improves the flexibility and adaptability of installation.

[0151] Furthermore, the water tank 200 is located below the heat collector 100, which does not obstruct the heat collector 100 and ensures the maximum exposure area of ​​the heat collector 100 under direct sunlight, thus enhancing heat absorption. At the same time, this layout also utilizes gravity to allow the heated water to flow naturally into the water tank 200, reducing energy consumption.

[0152] Combination Figure 7 As shown, in some embodiments, the bottom height of the water tank 200 is higher than the bottom height of the heat collection device 100.

[0153] Specifically, by optimizing the relative positions of the water tank 200 and the heat collection device 100, the water heater can better adapt to different installation environments and user needs, providing an efficient and reliable hot water solution.

[0154] When the position of the water tank 200 is lowered, the position of the heat exchange components can be lowered accordingly to ensure that the positions of the heat circulation inlet 210 and the heat circulation outlet 220 of the water tank 200 are always higher than the position of the heat exchange components.

[0155] This design facilitates the use of the principle of heat convection, allowing hot water to rise naturally and flow into the water tank 200, while cold water flows back from the water tank 200 to the heat exchange components for heating.

[0156] Combination Figure 1 As shown, in some embodiments, the water tank 200 is provided with a tank liner 230, which is used to hold at least hot water.

[0157] By installing a tank liner 230 in the water tank 200, hot water can be stored and kept warm more effectively.

[0158] The tank liner 230 is designed to provide a dedicated internal space for hot water, effectively isolating the hot water from the external environment and reducing heat loss.

[0159] In some embodiments, at least a portion of the heat collection device 100 extends into the liner 230.

[0160] By extending the heat collection device 100 into the tank liner 230, heat energy can be directly transferred from the heat collection device 100 to the water in the tank liner 230. This enables direct heat energy transfer, reducing heat loss through intermediate media. This direct contact method reduces heat loss during the transfer process, improving heating efficiency and response speed.

[0161] In some embodiments, the water tank 200 is provided with a tank liner 230, which is used to contain at least hot water; the tank liner 230 is connected to the liquid outlet 610 of the heat exchange component through the heat circulation inlet 210, and the tank liner 230 is connected to the liquid inlet 620 of the heat exchange component through the heat circulation outlet 220.

[0162] Understandably, the working fluid inside the heat exchanger is water.

[0163] The outlet end 610 of the heat exchange component can be connected to the heat circulation inlet 210 of the tank 230 via a hot water pipe 400; the heat circulation outlet 220 of the tank 230 can be connected to the inlet end 620 of the heat exchange component via a cold water pipe 500.

[0164] The tank 230 and the heat exchange components can form a closed loop system. Water heated by the heat collector 100 in the heat exchange components can flow directly into the tank 230 for storage, while unheated or uncooled water in the tank 230 can return to the heat exchange components for reheating, ensuring continuous operation and efficient heating of the water heater.

[0165] In some embodiments, both the liquid inlet 620 and the liquid outlet 610 of the heat exchange component may be equipped with antifreeze valves.

[0166] By installing antifreeze valves, the water in the hot water pipe 400 and cold water pipe 500 can be prevented from freezing in cold weather, ensuring that the heat exchange components can still work normally in low-temperature environments and maintaining the continuity and reliability of the water heater.

[0167] Specifically, the water heater provided in this application embodiment connects the heat exchange component to the tank 230, which ensures effective heat transfer while avoiding direct contact between the high-temperature heat collection device 100 and the water tank 200, ensuring that the water tank 200 operates within a safe temperature range and extending the service life of the water tank 200.

[0168] In some embodiments, the water tank 200 is provided with a tank liner 230 and a heat exchange box 240; the tank liner 230 is used to contain at least hot water, and the heat exchange box 240 is used to contain at least refrigerant; the heat collection device 100 extends at least partially into the heat exchange box 240.

[0169] Understandably, the inner tank 230 effectively stores and insulates hot water. The heat exchanger 240 not only effectively isolates hot water and refrigerant but also provides a dedicated space for refrigerant heat exchange.

[0170] By extending the heat collector 100 into the heat exchange box 240, heat energy can be directly transferred from the heat collector 100 to the refrigerant in the heat exchange box 240. This enables direct heat energy transfer, reduces heat loss during the transfer process, and improves heating efficiency and response speed.

[0171] For example, the heat exchange box 240 may be arranged around the outer periphery of the box liner 230.

[0172] This configuration increases the heat exchange area between the heat exchange box 240 and the inner tank 230, making it easier for the heat obtained in the heat exchange box 240 to be transferred to the water tank 200 more quickly, so as to rapidly heat the water in the water tank 200.

[0173] For example, the refrigerant can be antifreeze. Antifreeze can effectively prevent freezing in low-temperature environments, ensuring that the water heater can still operate normally in cold climates and enhancing the water heater's adaptability to diverse environments.

[0174] In some embodiments, the water tank 200 is provided with a tank liner 230 and a heat exchange box 240; the tank liner 230 is used to contain at least hot water, and the heat exchange box 240 is used to contain at least refrigerant; the heat collection device 100 includes a heat collection pipe 130, and the heat exchange box 240 is connected to the heat collection pipe 130.

[0175] The refrigerant can be water or ethanol, etc.

[0176] By connecting the heat exchange box 240 to the heat collector tube 130, the heat exchange box 240 can act as a heat exchange component and directly exchange heat with the heat collector tube 130.

[0177] The connection between the heat collection tube 130 and the heat exchange box 240 optimizes the heat transfer path and storage method, ensures the direct transfer of heat energy, reduces heat loss in intermediate links, and improves the overall energy efficiency of the water heater.

[0178] In addition, the direct connection between the heat collection tube 130 and the heat exchange box 240 facilitates insulation and sealing of the connection points, which helps reduce the risk of refrigerant leakage.

[0179] Combination Figure 6 As shown, in some embodiments, the water tank 200 is provided with a tank liner 230 and a heat exchange box 240; the tank liner 230 is used to contain at least hot water, and the heat exchange box 240 is used to contain at least refrigerant; the heat exchange box 240 is connected to the liquid outlet 610 of the heat exchange component through the heat circulation inlet 210, and the heat exchange box 240 is connected to the liquid inlet 620 of the heat exchange component through the heat circulation outlet 220.

[0180] For example, the refrigerant can be antifreeze.

[0181] The outlet end 610 of the heat exchange component can be connected to the heat circulation inlet 210 of the heat exchange box 240 through the hot water pipe 400. The heated refrigerant can flow into the heat exchange box 240 through the hot water pipe 400 for storage or further transfer.

[0182] The heat circulation outlet 220 of the heat exchanger 240 can be connected to the liquid inlet 620 of the heat exchange component via a cold water pipe 500, forming a closed loop system between the heat exchanger 240 and the heat exchange component. The cooled refrigerant can return to the heat exchange component via the cold water pipe 500 for reheating, ensuring continuous operation of the heat exchange process.

[0183] Specifically, the water heater provided in this application embodiment, by setting a heat exchange component connected to the heat exchange box 240, can ensure effective heat transfer while avoiding direct contact between the high-temperature heat collection device 100 and the water tank 200, ensuring that the water tank 200 operates within a safe temperature range and extending the service life of the water tank 200.

[0184] Combination Figure 1 and Figure 6 As shown, in some embodiments, the water heater also includes a support base 300. The bottom end of the support base 300 is used to fix it to the mounting base 90, and the top end of the support base 300 is connected to the water tank 200.

[0185] Understandably, by setting up the support base 300, the water tank 200 can be supported.

[0186] The bottom of the support base 300 is fixed on the installation base 90, and the top of the support base 300 is connected to the water tank 200, which can form a stable support structure and reduce the tilting or movement of the water tank 200 due to external forces or environmental factors (such as wind and vibration).

[0187] In some embodiments, the support base 300 is provided with a plurality of pull rods 310, and one end of the pull rod 310 away from the support base 300 is disposed on the heat collection device 100.

[0188] One end of the pull rod 310 is connected to the support base 300, and the other end is connected to the second surface of the heat absorption plate 110.

[0189] The tie rod 310 can provide support for the heat absorber plate 110, stabilize the installation position of the heat absorber plate 110, and ensure its stability at different angles and positions.

[0190] The support provided by the tie rod 310 reduces the shaking or deformation of the water heater under wind or other external forces, thus improving the stability and durability of the water heater.
