[0019] In a possible design, the heat collecting pipe comprises a plurality of surrounding segments arranged on the outer side of the heat exchange member;

[0020] The plurality of surrounding segments are arranged in sequence and spaced apart between the liquid inlet end of the heat exchange member and the liquid outlet end of the heat exchange member.

[0021] The heat collecting pipe further comprises a plurality of transition segments connecting two adjacent surrounding segments.

[0023] The plurality of surrounding segments are arranged in sequence and spaced apart between the liquid inlet end of the heat exchange member and the liquid outlet end of the heat exchange member.

[0024] In a possible design, the heat collecting pipe comprises a plurality of extending segments arranged on the inner side of the heat exchange member;

[0037] The water heater of this application makes full use of the natural law that hot water rises and cold water falls, maintaining the heat transfer process between the heat exchanger and the water tank. This allows the circulating liquid to circulate between the heat exchanger and the water tank without additional power, reducing the complexity of the liquid circulation mode between the heat collection device and the water tank, and improving the overall reliability of the water heater's operation.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Unless otherwise stated, the term "multiple" means two or more.

[0061] As can be seen from the background technology, in order to continuously maintain the heat transfer process, a pumping system is usually configured between the heat collection device and the water tank in existing solar water heaters.

[0062] The core of the pumping system lies in using a circulating liquid (usually water or a special heat-conducting medium) as a carrier to transfer the solar radiation heat energy captured on the heat collection device to the water in the water tank.

[0063] The pumping system provides the necessary power to the circulating liquid through its built-in electric pump or solar-powered pump, ensuring that it can form a closed circulation loop between the solar collector and the water tank.

[0064] During the circulation process, the circulating liquid first flows through the heat collection device, absorbing heat energy converted from solar radiation, and its temperature rises accordingly. Subsequently, the heated liquid is pushed to the water tank area by the action of the pump.

[0065] Inside the water tank, the high-temperature liquid exchanges heat with the water to be heated, releasing the heat energy it carries to the water, thereby heating the water.

[0066] After heat exchange is complete, the cooled circulating liquid is pumped back to the heat collection device to begin a new round of heat absorption. This cyclical process ensures that heat can be continuously transferred from the heat collection device to the water tank.

[0067] However, while the circulating liquid driven by the pumping system effectively maintains heat transfer, the liquid circulation process is relatively complex. It requires not only a pumping system but also flow control and temperature monitoring of the circulating liquid. This not only increases the manufacturing cost and maintenance difficulty of solar water heaters but may also lead to problems such as liquid leakage and pumping failures during operation, affecting the stability and lifespan of the water heater.

[0068] In view of this, the present application provides a water heater, including a heat collection device, a heat exchanger and a water tank; the heat collection device includes a heat absorption plate, the heat exchanger is disposed on the heat absorption plate, the heat exchanger is inclined, and the height of the liquid inlet end of the heat exchanger is lower than the height of the liquid outlet end of the heat exchanger.

[0069] After heat exchange occurs between the heat exchanger and the heat collector, the temperature of the liquid inside the heat exchanger will rise. Therefore, there is a density difference between the liquids at different temperatures inside the heat exchanger, with the warmer liquid flowing towards the higher outlet end.

[0070] The heat circulation inlet of the water tank is connected to the liquid outlet of the heat exchanger. The high-temperature liquid at the liquid outlet of the heat exchanger will flow into the water tank during the rising process and exchange heat with the water in the water tank, so that the water in the water tank can be heated.

[0071] The hot circulation outlet of the water tank is connected to the liquid inlet of the heat exchanger, allowing the cooler liquid in the water tank to flow towards the lower inlet and enter the heat exchanger. The liquid entering the heat exchanger exchanges heat with the heat collector and is heated. The heated liquid can then re-enter the water tank from the outlet of the heat exchanger to further heat the water in the tank.

[0072] It can be seen that the above circulation method makes full use of the natural law of hot water rising and cold water falling, and can maintain the heat transfer process between the heat exchanger and the water tank without the need for additional power.

[0073] Specifically, the water heater in this application eliminates the reliance on a pumping system, reducing the complexity of the liquid circulation method between the heat collection device and the water tank. This not only helps to reduce manufacturing costs and maintenance difficulties, but also helps to improve the overall operational reliability.

[0074] 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.

[0075] Combination Figure 1 As shown in the figure, this application provides a water heater, including a heat collection device 100, a heat exchanger 600, and a water tank 200.

[0076] The solar collector 100 includes a heat absorber plate 110, which can be used to obtain solar thermal energy.

[0077] In some embodiments, the heat exchanger 600 is disposed on the heat absorber plate 110. The heat energy generated by the heat absorber plate 110 can be transferred to the heat exchanger 600 to realize heat conduction between the heat collection device 100 and the heat exchanger 600.

[0078] In some embodiments, the water tank 200 has a heat circulation inlet 210 and a heat circulation outlet 220, the heat circulation inlet 210 being connected to the liquid outlet 610 of the heat exchanger 600, and the heat circulation outlet 220 being connected to the liquid inlet 620 of the heat exchanger 600.

[0079] The heat exchanger 600 is connected to the water tank 200. After receiving the heat energy from the heat collection device 100, the heat exchanger 600 can transfer the heat to the water tank 200 to heat the water in the water tank 200 to meet the user's hot water needs.

[0080] In some embodiments, the extending direction of the heat exchanger 600 forms an angle with the width direction of the heat absorber plate 110, and the height of the liquid inlet end 620 of the heat exchanger 600 is lower than the height of the liquid outlet end 610 of the heat exchanger 600.

[0081] It should be noted that the width direction of the heat absorber plate 110 is parallel to... Figure 1 In the X direction, the height direction of the water heater is parallel to... Figure 1 The Z-direction in the middle.

[0082] Understandably, the liquid inlet end 620 of the heat exchanger 600 is... Figure 1 The height of the Z-axis is lower than the liquid outlet end 610 of the heat exchanger 600. Figure 1 The heat exchanger is tilted 600 degrees at the top height in the Z-direction.

[0083] Heat exchanger 600 conducts heat with heat collector 100. When the liquid in heat exchanger 600 is heated, the temperature rises and the density decreases, so the liquid will naturally rise and flow to the higher liquid outlet 610.

[0084] The high-temperature liquid located at the liquid outlet 610 of the heat exchanger 600 will flow into the water tank 200 during the rising process and exchange heat with the water in the water tank 200, so that the water in the water tank 200 can be heated.

[0085] The cooler liquid in the water tank 200 can flow to the lower inlet end 620 and enter the heat exchanger 600. The liquid entering the heat exchanger 600 exchanges heat with the heat collector 100 and is heated. The heated liquid can then enter the water tank 200 again from the outlet end 610 of the heat exchanger 600 to further heat the water in the water tank 200.

[0086] With this configuration, the water tank 200 and the heat exchanger 600 can form a closed thermal circulation loop. High-temperature liquid can flow from the outlet 610 of the heat exchanger 600 into the water tank 200, enter through the thermal circulation inlet 210, and exchange heat with the water in the water tank 200. The cooled liquid flows out from the thermal circulation outlet 220 of the water tank 200 and enters the inlet 620 of the heat exchanger 600, where it is reheated.

[0087] This heat circulation loop makes full use of the natural law that hot water rises and cold water falls, and can maintain the heat transfer process between the heat exchanger and the water tank without the need for additional power.

[0088] The water heater in this embodiment eliminates the reliance on a pumping system, which not only simplifies the water heater's structure and reduces manufacturing and maintenance costs, but also improves its reliability and lifespan. The absence of a mechanical pump reduces the risk of failure and energy consumption, making the water heater more environmentally friendly and economical.

[0089] 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.

[0090] The water heater provided in this application embodiment is configured with a heat exchanger 600 and a heat collection device 100 for heat conduction, and the heat exchanger 600 is connected to a water tank 200. The heat exchanger 600 serves as an intermediate medium between the water tank 200 and the heat collection device 100, and can regulate the temperature 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.

[0091] For example, the heat exchanger 600 can be configured as a detachable or standardized form, making it 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 can adapt to diverse user needs and installation scenarios.

[0092] Combination Figure 2 and Figure 1 As shown, in some embodiments, the height of the liquid inlet 620 of the heat exchanger 600 is not higher than the height of the heat cycle outlet 220, and the height of the liquid outlet 610 of the heat exchanger 600 is not higher than the height of the heat cycle inlet 210.

[0093] Understandably, the liquid inlet end 620 of the heat exchanger 600 is... Figure 1 The height of the Z-axis should not be higher than the heat circulation outlet 220. Figure 1 The height of the Z-axis; the liquid outlet end 610 of the heat exchanger 600 is at... Figure 1 The height of the Z-axis should not be higher than the heat cycle inlet 210. Figure 1 The height of the Z-axis upwards.

[0094] This configuration ensures that the fluid circulation path between the heat exchanger 600 and the water tank 200 remains unobstructed, preventing fluid stagnation or backflow in the circulation path.

[0095] In practice, the hot liquid inside the heat exchanger 600 will continue to flow upward after reaching the outlet 610 and enter the water tank 200 through the heat circulation inlet 210 to heat the water in the water tank 200.

[0096] 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 exchanger 600 from the liquid inlet end 620 and then exchange heat with the heat collection device 100.

[0097] In this way, a stable fluid circulation is achieved between the water tank 200 and the heat exchanger 600, ensuring the effective transfer of heat energy between the water tank 200 and the heat exchanger 600.

[0098] Specifically, the water heater provided in this application embodiment optimizes the flow path of the fluid by controlling the relative positions of the liquid outlet 610 and the heat circulation inlet 210, as well as the relative positions of the liquid inlet 620 and the heat circulation outlet 220, utilizing height differences and fluid dynamic characteristics. This enables the water heater to achieve efficient heat transfer and water heating without additional power.

[0099] Combination Figure 2As shown, in some embodiments, the liquid inlet end 620 of the heat exchanger 600 is close to the first end in the width direction of the heat absorber plate 110, and the liquid outlet end 610 of the heat exchanger 600 is close to the second end in the width direction of the heat absorber plate 110.

[0100] Understandably, the liquid entering the heat exchanger 600 from the heat circulation outlet 220 has a lower temperature.

[0101] By setting the liquid inlet 620 at the first end of the heat absorber plate 110, the liquid can flow along the entire width of the heat absorber plate 110 when it flows through the heat exchanger 600, thus fully absorbing the heat energy transferred by the heat absorber plate 110 and improving the heating efficiency of the liquid.

[0102] As the liquid flows through the heat exchanger 600, its temperature gradually increases with the distance traveled. By positioning the liquid outlet 610 at the second end of the absorber plate 110, the liquid can continuously absorb heat during its flow, ensuring that it reaches a higher temperature upon reaching the liquid outlet 610, thereby improving the efficiency of heat transfer.

[0103] In some embodiments, the extending direction of the water tank 200 is parallel to the width direction of the heat absorption plate 110.

[0104] The width direction of the heat absorber plate 110 is typically the main direction of heat distribution. By arranging the extension direction of the water tank 200 parallel to the width direction of the heat absorber plate 110, the water tank 200 can uniformly receive heat throughout its entire extension direction, thereby improving the heating uniformity and efficiency of the water in the water tank 200.

[0105] In some embodiments, the heat circulation inlet 210 and the heat circulation outlet 220 are respectively located at both ends of the water tank 200 in the extending direction.

[0106] When the high-temperature liquid enters the water tank 200 through the heat circulation inlet 210, it flows along the extension direction of the water tank 200 and exchanges heat with the water inside the water tank 200. By setting the heat circulation outlet 220 at the other end, it is ensured that the liquid flows through the entire water tank 200 before leaving, thus maximizing the efficiency and effect of heat exchange.

[0107] With this configuration, the flow path of the liquid in the water tank 200 is extended as much as possible, increasing the time and area for heat exchange and improving the efficiency of heat transfer.

[0108] Specifically, the water heater provided in this application embodiment optimizes the spatial layout of the water tank 200 and the heat absorption plate 110. The long path flow of liquid in the water tank 200 increases the time and area of ​​heat exchange, improves the heating efficiency of water, and makes the heat transfer more efficient and uniform.

[0109] CombinationFigure 1 As shown, in some embodiments, the heat absorber plate 110 has a first surface and a second surface disposed opposite to each other, and the first surface of the heat absorber plate 110 is used to absorb heat energy.

[0110] The first surface of the heat absorber 110 faces the sun to fully absorb solar heat energy. The second surface faces the mounting base 90 and can be used to transfer heat energy. After the first surface of the heat absorber 110 absorbs solar heat energy, the heat energy can be transferred to the second surface through the thermal conductivity of the material.

[0111] 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.

[0112] Combination Figure 2 As shown, in some embodiments, the heat collection device 100 further includes a heat collection tube 130 disposed on the second surface of the heat absorption plate 110.

[0113] The heat collection tube 130 can be set close to the second surface of the heat absorption plate 110, and the heat absorption plate 110 can efficiently transfer the absorbed heat energy to the heat collection tube 130, reducing heat loss.

[0114] In some embodiments, the heat exchanger 600 is disposed on the second surface of the heat absorber plate 110, and the heat collection tube 130 is connected to the heat exchanger 600, and the heat collection tube 130 conducts heat with the heat exchanger 600.

[0115] By connecting the heat collection tube 130 to the heat exchanger 600, the heat collection tube 130 can effectively transfer the received 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.

[0116] 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.).

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Combination Figure 2 As shown, in some embodiments, the water tank 200 faces the second surface of the heat absorber plate 110.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] Furthermore, since the water tank 200 is close to the second surface of the heat absorber plate 110, at least part of the water tank 200 will be 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, thereby improving the overall durability of the water heater.

[0125] In some embodiments, the water tank 200 and the heat absorption plate 110 at least partially overlap in the horizontal direction.

[0126] The horizontally overlapping design of the water tank 200 and the heat collection device 100 can effectively reduce the height of the water heater.

[0127] 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.

[0128] Furthermore, the water tank 200 may not extend completely beyond the plane area where the heat collection device 100 is located, thereby 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.

[0129] Combination Figure 3 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, and the bottom height of the water tank 200 is higher than the bottom height of the heat collection device 100.

[0130] By limiting the height of the water tank 200, the water tank 200 will not completely exceed the plane area where the heat collection device 100 is located, which helps to reduce the horizontal footprint of the water heater and improves the flexibility and adaptability of installation.

[0131] 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.

[0132] In some embodiments, the liquid outlet 610 of the heat exchanger 600 can be connected to the heat circulation inlet 210 via a hot water pipe 400, and the heat circulation outlet 220 can be connected to the liquid inlet 620 of the heat exchanger 600 via a cold water pipe 500.

[0133] Combination Figure 1 As shown, when the position of the water tank 200 is lowered, the position of the heat exchanger 600 can be lowered accordingly. While ensuring that the heat circulation inlet 210 and heat circulation outlet 220 of the water tank 200 are always higher than the heat exchanger 600, the length of the hot water pipe 400 and the cold water pipe 500 can also be reduced, promoting efficient liquid circulation.

[0134] 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 exchanger 600 for heating.

[0135] In some embodiments, the heat collection tube 130 may include a connecting section and multiple heat collection sections. Multiple heat collection sections are arranged in parallel along the width direction of the absorber plate 110, and are connected end-to-end 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.

[0136] 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.

[0137] 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.

[0138] The connecting section serves as the inlet and outlet of the heat collection section group, and plays a role in guiding fluid and connecting the pathways.

[0139] The connecting section ensures smooth flow of fluid when entering and leaving the collector section group, allowing the fluid to circulate efficiently within the collector tube 130.

[0140] Combination Figure 4 As shown, in some embodiments, the heat collection tube 130 includes a plurality of circumferential sections 131, which are arranged around the outside of the heat exchanger 600.

[0141] 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.

[0142] 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 of the heat exchanger 600 can be avoided, thereby reducing the risk of liquid leakage inside the heat exchanger 600.

[0143] Furthermore, positioning the surrounding section 131 on the outside of the heat exchanger 600 supports modular installation, allowing 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.

[0144] In some embodiments, a plurality of circumferential segments 131 are sequentially spaced between the liquid inlet end 620 and the liquid outlet end 610 of the heat exchanger 600.

[0145] Understandably, the design of multiple surrounding sections 131 allows heat to be transferred at more than 600 locations on the heat exchanger, reducing the heat load at any single location and improving heat utilization.

[0146] Multiple surrounding sections 131 are arranged at intervals, which also increases the contact area between the heat collection tube 130 and the heat exchanger 600.

[0147] According to the basic principles of heat conduction, increasing the contact area can enhance the heat transfer effect. By increasing the contact area between the heat collector tube 130 and the heat exchanger 600, it can be ensured that heat energy can be transferred quickly and evenly from the heat collector tube 130 to the heat exchanger 600.

[0148] In some embodiments, the heat collection tube 130 further includes a transition section 132, which connects two adjacent surrounding sections 131.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] This configuration reduces the steam flow path, which helps to achieve efficient heat exchange between the collector tube 130 and the heat exchanger 600.

[0153] Combination Figure 5 As shown, in some embodiments, a plurality of circumferential segments 131 are connected in sequence between the liquid inlet end 620 and the liquid outlet end 610 of the heat exchanger 600.

[0154] The surrounding section 131 can be installed at the connection section of the heat collector tube 130. The sequentially connected surrounding sections 131 can improve the modularity of the heat collector tube 130, help simplify the assembly process of the heat collector tube 130, and make manufacturing and installation more convenient. At the same time, this modular design also facilitates the assembly of the heat collector tube 130 and the heat exchanger 600, improving the overall installation efficiency and maintenance convenience.

[0155] Combination Figure 6 As shown, in some embodiments, the heat collection tube 130 includes a plurality of extension sections 133, which are arranged sequentially and at intervals between the liquid inlet end 620 and the liquid outlet end 610 of the heat exchanger 600.

[0156] Understandably, the design of multiple extension sections 133 allows heat to be transferred at more than 600 locations on the heat exchanger, reducing the heat load at any single location and improving the efficiency of heat utilization.

[0157] Multiple extension sections 133 are arranged at intervals in sequence, which increases the contact area between the heat collection tube 130 and the heat exchanger 600, ensuring that heat energy can be transferred quickly and evenly from the heat collection tube 130 to the heat exchanger 600.

[0158] In some embodiments, the extension 133 is disposed on the inner side of the heat exchanger 600.

[0159] 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.

[0160] 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.

[0161] By placing the extension section 133 inside the receiving cavity 601, the advantage of direct contact is utilized, which shortens the heat transfer path, reduces heat loss, and improves transfer efficiency, thereby improving the efficiency of heat transfer.

[0162] 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.

[0163] 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.

[0164] In some embodiments, the heat collection tube 130 includes a transition section 132 that connects two adjacent extension sections 133.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] Combination Figure 2 As shown, in some embodiments, multiple extension sections 133 are connected in sequence between the liquid inlet end 620 and the liquid outlet end 610 of the heat exchanger 600.

[0169] The extension section 133 can flexibly adapt to different heat exchanger 600 structures, increasing the contact area with the heat exchanger 600, thereby improving the efficiency of heat transfer.

[0170] Extension section 133 can be provided at the connection section of collector tube 130. Multiple sequentially connected extension sections 133 facilitate assembly, improve the modularity of collector tube 130, and make the manufacturing and installation of collector tube 130 more convenient. At the same time, this modular design also facilitates the assembly of collector tube 130 and heat exchanger 600.

[0171] Combination Figure 7 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.

[0172] By setting a tank liner 230 in the water tank 200, a dedicated internal space for containing hot water is provided, which can effectively isolate hot water from the external environment, allowing hot water to be stored and kept warm more effectively, reducing heat loss.

[0173] In some embodiments, the tank liner 230 is connected to the liquid outlet 610 of the heat exchanger 600 through the heat circulation inlet 210, and the tank liner 230 is connected to the liquid inlet 620 of the heat exchanger 600 through the heat circulation outlet 220.

[0174] It is understandable that the refrigerant inside the heat exchanger 600 is water.

[0175] The tank 230 and the heat exchanger 600 can form a closed loop system. The water heated by the heat collector 100 in the heat exchanger 600 can flow directly into the tank 230 for storage, while the water that is not heated or cooled in the tank 230 can return to the heat exchanger 600 for reheating, ensuring the continuous operation and efficient heating of the water heater.

[0176] In some embodiments, both the liquid inlet 620 and the liquid outlet 610 of the heat exchanger 600 may be equipped with antifreeze valves.

[0177] By installing an antifreeze valve, 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 exchanger 600 can still work normally in low-temperature environments and maintaining the continuity and reliability of the water heater.

[0178] Specifically, the water heater provided in this application embodiment connects the heat exchanger 600 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.

[0179] Combination Figure 2 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.

[0180] Understandably, the inner tank 230 can effectively store and keep hot water warm. The heat exchanger 240 can not only effectively isolate hot water and refrigerant, but also provide a dedicated space for heat exchange of the refrigerant.

[0181] In some embodiments, the heat exchange box 240 is connected to the liquid outlet 610 of the heat exchange element 600 through the heat circulation inlet 210, and the heat exchange box 240 is connected to the liquid inlet 620 of the heat exchange element 600 through the heat circulation outlet 220.

[0182] The outlet end 610 of the heat exchanger 600 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 to exchange heat with the water in the box liner 230.

[0183] The heat circulation outlet 220 of the heat exchanger 240 can be connected to the liquid inlet 620 of the heat exchanger 600 via a cold water pipe 500, thus forming a closed-loop circulation system between the heat exchanger 240 and the heat exchanger 600. The cooled refrigerant can return to the heat exchanger 600 via the cold water pipe 500 for reheating, ensuring continuous operation of the heat exchange process.

[0184] For example, the heat exchange box 240 may be arranged around the outer periphery of the box liner 230.

[0185] 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.

[0186] 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.

[0187] Combination Figure 7 and Figure 2 As shown, in some embodiments, the water heater also includes a support base 300; a first end of the support base 300 is used to fix it to the mounting base 90, and a second end of the support base 300 is connected to the water tank 200.

[0188] Understandably, the first end of the support 300 is opposite to the support 300. Figure 2 One end of the support 300 is in the Z-direction direction, and the second end of the support 300 is oriented towards the Z-direction direction. ​ One end in the Z direction.

[0189] The first end of the support base 300 is fixed on the mounting base 90, and the second end 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).

[0190] 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 connected to the heat collection device 100.

[0191] 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.

[0192] 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.

[0193] 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.
