[0037] The embodiments of this utility model are described in detail below.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following is for reference. Figures 1-12The heating device 100 according to an embodiment of the present utility model, by setting up the heating component 2, the water pipe component 3 and the heat conductor 1 to work together, can enable the heating component 2 to transfer heat to the water pipe component 3 through the heat conductor 1, and the heat transfer is uniform and the heating efficiency is high. Moreover, the heating component 2 and the water pipe component 3 will not be in direct contact, so the heating component 2 and the water pipe component 3 can be separated, avoiding the heating component 2 from water corrosion and thermal shock, which can improve the service life of the heating component 2. The overall structure has high reliability, good heating effect and high safety.

[0041] like Figures 1-12 As shown, a heating device 100 according to an embodiment of the present invention includes: a heat conductor 1, a heating component 2, and a water pipe component 3.

[0042] The heating device 100 is a device that converts electrical energy or other forms of energy into heat energy and transfers heat through a specific structure to meet the heat requirements of certain devices. In this embodiment, the heating device 100 is used to transfer heat energy to a heat transfer medium, thereby enabling the heating device 100 to provide heat to the corresponding device through the heat transfer medium.

[0043] Furthermore, the heat conductor 1 refers to an object capable of conducting heat energy. Objects that are good conductors of heat are called good conductors of heat, while those that are not good conductors of heat are called poor conductors of heat. The heat conductor 1 itself does not generate heat; it transfers heat through its heat transfer properties. The heating component 2 is a part that converts electrical energy or other forms of energy into heat energy. The heating component 2 can be constructed as a heating wire, heating tube 21, etc. The water pipe assembly 3 is a component in the heating device 100 used for transporting water.

[0044] Heating component 2 and water pipe component 3 are both located inside heat conductor 1. Heating component 2 and water pipe component 3 are distributed at intervals and conduct heat through heat conductor 1.

[0045] Specifically, such as Figures 4-6 As shown, both the heating component 2 and the water pipe component 3 are disposed within the heat conductor 1. The heating component 2 can generate heat, and the water pipe component 3 is used to circulate water and can receive heat. This allows the heat from the heating component 2 to be transferred to the water pipe component 3 within the heat conductor 1. Heat transfer within the heat conductor 1 reduces the outward diffusion of heat from the heat conductor 1, thereby improving the heat transfer effect of the heat conductor 1.

[0046] The heating element 2 and the water pipe assembly 3 are spaced apart, and the space between them is filled by a heat conductor 1. In this way, heat can be transferred between them through the heat conductor 1. The separation between the heating element 2 and the water pipe assembly 3 prevents direct contact between them, which reduces the overheating of the water pipe assembly 3 by the heating element 2. This reduces the expansion and pressure increase of the water in the water pipe assembly 3 due to heat, and may even cause the water pipe to rupture or leak, thus improving safety. In addition, the separation can control the water temperature, allowing heat to be transferred more evenly to the water in the water pipe assembly 3, avoiding the phenomenon of some areas being too hot and some areas being too cold.

[0047] Furthermore, the water pipe assembly 3 includes a heating water pipe 31, which is wrapped around the heating component 2. In other words, the heating water pipe 31 is distributed around the heating component 2. The space formed inside the heating water pipe 31 can be used for the arrangement of the heating component 2. With this arrangement, after the heating component 2 generates heat, it will be transferred to the heating water pipe 31 in multiple directions around the periphery. The water flow inside the heating water pipe 31 absorbs the heat, and the water flow inside the heating water pipe 31 will continue to flow, so that the heat of the heating component 2 can be continuously transferred to the water flow inside the heating water pipe 31. Moreover, the heating water pipe 31 is connected to the external water circuit, so it can continuously supply heat to the external heating equipment.

[0048] Traditional air-source heat pump heating systems, particularly in cold regions during winter, suffer from reduced heating efficiency due to low temperatures, failing to meet demand and limiting their widespread adoption. Purchasing higher-powered units to address this issue is costly. While existing electric heating devices 100 avoid the effects of low temperatures, the heating element 21, directly immersed in water, is subject to corrosion and thermal shock, increasing the risk of cracking and electrical leakage. Furthermore, when installed outside the water system, their heat transfer is poor, leading to stratification within the pipes and hindering heat transfer to the water.

[0049] In this embodiment, the heating water pipe 31 is wrapped around the heating component 2, which avoids direct contact between the heating component 2 and the water, thus achieving separation between the heating component 2 and the water pipe component 3. The heating component 2 will not be corroded by water or subjected to cold shocks, and the heating component 2 will not crack, thus preventing leakage and ensuring high safety. Furthermore, the heating component 2 and the heating water pipe 31 are located inside the heat conductor 1, which can improve the heat transfer efficiency between the heating water pipe 31 and the heating component 2, thereby improving the heating capacity of the heating device 100.

[0050] In some embodiments, the water pipe assembly 3 further includes an inlet component 32 and an outlet component 33, and there are at least two heating water pipes 31, with at least two heating water pipes 31 connected in parallel between the inlet component 32 and the outlet component 33.

[0051] Specifically, the water inlet component 32 is used for water inlet of the water pipe assembly 3, the water outlet component 33 is used for water outlet of the water pipe assembly 3, and the heating water pipe 31 is connected between the water inlet component 32 and the water outlet component 33, which can realize the water circuit arrangement of the water pipe assembly 3.

[0052] Furthermore, at least two heating water pipes 31 are provided, and both heating water pipes 31 are wrapped around the heating component 2. The two ends of the at least two heating water pipes 31 are respectively connected to the water inlet component 32 and the water outlet component 33. In this way, the water from the external water path enters the water inlet component 32 and is diverted to enter the at least two heating water pipes 31. After being heated in each heating water pipe 31, the water flows to the water outlet component 33 and flows out of the heating device 100 from the water outlet component 33.

[0053] Therefore, by setting at least two heating water pipes 31 in parallel between the water inlet component 32 and the water outlet component 33, the contact area between the heating water pipes 31 and the heating component 2 can be increased, thereby increasing the heat exchange area between them. The water flow can be evenly distributed through the water inlet component 32 and the water outlet component 33, thereby improving the heat transfer efficiency and heat transfer uniformity between the heating component 2 and the water pipe assembly 3.

[0054] The heat conductor 1 can be constructed as a square structure, and the water inlet component 32 and the water outlet component 33 can be disposed at both ends along the length of the heat conductor 1, and as shown in the figure. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 10 and Figure 11 As shown, the water inlet component 32 and the water outlet component 33 can be located on the same side of the heat conductor 1 and connected to the external water passage on the same side of the heating device 100. Alternatively, the water inlet component 32 and the water outlet component 33 can be located on opposite sides of the heat conductor 1. The arrangement is varied and can be flexibly selected according to actual space requirements. Furthermore, there can be two or three heating water pipes 31.

[0055] In some embodiments, there are two heating water pipes 31, which are spirally wound around the heating assembly 2, and the two heating water pipes 31 are spiraled in opposite directions.

[0056] Specifically, such as Figure 7 , Figure 8As shown, two heating water pipes 31 are spirally wound around the heating component 2, allowing them to be distributed around the outer periphery of the heating component 2. This increases the contact area between the two heating water pipes 31 and the heating component 2, enabling faster and more uniform heat transfer. Furthermore, the opposite spiral directions of the two heating water pipes 31 help to counteract some of the thermal stress generated by heating, resulting in more uniform heating of the water pipe assembly 3 and preventing localized overheating or undercooling. This promotes efficient heat transfer, and uniform heating reduces stress on the heating component 2 caused by thermal expansion and contraction, thereby reducing the risk of damage due to stress concentration and extending the service life of the heating component 2. The opposite spiral directions of the two heating water pipes 31 also make the overall structure more compact and efficient.

[0057] The heating component 2 can be configured as a heating tube 21. After the heating tube 21 is powered on and heated, the water in the two heating water pipes 31 flows in opposite directions and in opposite spiral paths. The water in the two heating water pipes 31 can absorb the heat from the heating tube 21 at the same time, which can raise the temperature of the water in the two heating water pipes 31, thereby achieving rapid heating of the water in the heating water pipes 31.

[0058] Furthermore, by setting two heating water pipes 31, the diameter of a single heating water pipe 31 can be reduced, and the water flow rate of the two heating water pipes 31 can be increased, thereby improving the heat exchange efficiency between the heating water pipes 31 and the heating component 2.

[0059] In some embodiments, each heating water pipe 31 includes at least one bent pipe section 311 and at least two straight pipe sections 312. The at least two straight pipe sections 312 are distributed along the length of the heating assembly 2, and two adjacent straight pipe sections 312 are connected by a bent pipe section 311.

[0060] Specifically, the two heating water pipes 31 can be configured in the same way, such as... Figure 7 , Figure 10 and Figure 11 As shown, the heating water pipe 31 includes a straight pipe section 312 and a bent pipe section 311. There are at least two straight pipe sections 312, which are spaced apart along the length of the heating component 2. Adjacent straight pipe sections 312 are connected by a bent pipe section 311. The two straight pipe sections 312 and one bent pipe section 311 are distributed around the heating component 2, which allows the heating water pipe 31 to be wrapped around the heating component 2, thereby increasing the contact area between the heating water pipe 31 and the heating component 2 and thus increasing the heat exchange area between them.

[0061] The bent pipe section 311 can be one, two, three, or four, and the straight pipe section 312 can be two, three, or four. The bent pipe section 311 can be constructed as an arc-shaped section, allowing for continuity between adjacent straight pipe sections 312 and enabling angle variations to achieve a spiral winding around the heating element 2. The bent pipe section 311 ensures the heating water pipe 31 fits tightly against the exterior of the heating element 2, maintaining effective heat transfer. Compared to using only straight pipe sections 312, this allows for smoother water flow, increases flow velocity, and alleviates thermal stress caused by heating to some extent. The bent pipe section 311 releases some stress, reducing stress concentration caused by thermal expansion and contraction in the straight pipe section 312, thus extending the service life of the heating water pipe 31. Furthermore, the overall structure of the heating water pipe 31 is more stable, stronger, and provides better heating performance.

[0062] Furthermore, the number of bent pipe sections 311 and straight pipe sections 312 is not limited to that described in this embodiment, but mainly depends on the length of the heating component 2 and the length of the heat conductor 1. Its arrangement is highly flexible, selective, and applicable to a wider range of situations.

[0063] In some embodiments, the straight pipe segments 312 of the two heating water pipes 31 are distributed parallel to each other in the thickness direction of the heating component 2, and the bent pipe segments 311 of the two heating water pipes 31 are distributed crosswise in the width direction of the heating component 2.

[0064] Specifically, such as Figure 8 As shown, in the thickness direction of the heating component 2, the straight pipe segments 312 of the two heating water pipes 31 are arranged in parallel and spaced apart, so that the water flow in the two heating water pipes 31 is distributed on both sides of the thickness direction of the heating component 2. That is, the straight pipe segments 312 of the two heating water pipes 31 respectively transfer heat to the heating component 2 in its thickness direction, which can ensure that the heat is evenly distributed in the thickness direction of the heating component 2, while avoiding the thermal stress problem caused by excessive heat concentration.

[0065] And such as Figure 7 , Figure 9 , Figure 11 and Figure 12 As shown, in the width direction of the heating component 2, the bent pipe segments 311 of the two heating water pipes 31 are distributed in a cross manner, so that the bent pipe segment 311 of one heating water pipe 31 extends from one side to the other side in the thickness direction of the heating component 2, and the bent pipe segment 311 of the other heating water pipe 31 extends from the other side to one side in the thickness direction of the heating component 2, so as to achieve the cross distribution of the two bent pipe segments 311. That is, in the width direction of the heating component 2, one bent pipe segment 311 bends close to the heating component 2, and the other bent pipe segment 311 bends away from the heating component 2. In this arrangement, the two bent pipe segments 311 can transfer heat at both ends in the width direction of the heating component 2.

[0066] Therefore, through the above arrangement, the two heating water pipes 31 can be wound around the heating component 2 in the thickness and width directions respectively, so that the two heating water pipes 31 are evenly distributed outside the heating component 2, and the two heating water pipes 31 are well embedded together. The two heating water pipes 31 do not interfere with each other, and the heat transfer is not affected. Moreover, the heat distribution of the two heating water pipes 31 is more uniform, which can improve the heat exchange efficiency between the heating water pipes 31 and the heating component 2. The structure is reliable and the heat exchange stability is high.

[0067] In some embodiments, among the two heating water pipes 31, the distance between two adjacent straight pipe segments 312 of one heating water pipe 31 is greater than the outer diameter of the straight pipe segment 312 of the other heating water pipe 31.

[0068] Specifically, each heating water pipe 31 is spirally wound around the heating assembly 2. The distance between two adjacent straight pipe segments 312 of the same heating water pipe 31 is greater than the outer diameter of the straight pipe segment 312 of the other heating water pipe 31. In this way, the two heating water pipes 31 can be alternately distributed along the length of the heating assembly 2. The arrangement of the two heating water pipes 31 can be realized in enough space, and the outer diameter of a single heating water pipe 31 can be increased. The bending radius can also be increased, making it easier to process and convenient to embed another water pipe inside one water pipe, making the arrangement of the two heating water pipes 31 easier to realize.

[0069] Thus, through the above arrangement, the two heating water pipes 31 can be staggered and spirally distributed along the length of the heating component 2, and the two heating water pipes 31 can fit together well, making the overall arrangement of the water pipe assembly 3 smoother and more orderly, and making the distribution of the water pipe assembly 3 outside the heating component 2 more uniform, resulting in more uniform and reliable heat exchange.

[0070] In some embodiments, the straight pipe segments 312 at both ends of each heating water pipe 31 are connected to the water inlet component 32 and the water outlet component 33, respectively. Each heating water pipe 31 has an inlet side and an outlet side, and the inlet side and outlet side of each heating water pipe 31 are distributed at the ends of the corresponding straight pipe segments 312, such as... Figure 7 As shown, the inlet side of each heating water pipe 31 is connected to the inlet component 32, and the outlet side of each heating water pipe 31 is connected to the outlet component 33. In this way, each heating water pipe 31 can be connected to both the inlet component 32 and the outlet component 33, so that water can be supplied to and discharged from each heating water pipe 31 through the inlet component 32 respectively. This allows two heating water pipes 31 to have one inlet component 32 and one outlet component 33 at the same time. The overall structure is simple and easy to assemble.

[0071] Furthermore, straight pipe sections 312 at both ends of each heating water pipe 31 are connected to the water inlet component 32 and the water outlet component 33, respectively. The straight pipe sections 312 can be arranged horizontally, which makes the water inlet and outlet structure of the heating water pipe 31 simpler and more convenient, facilitates the connection and disassembly of the heating water pipe 31 with the external water circuit, and reduces maintenance costs.

[0072] In some embodiments, both the water inlet component 32 and the water outlet component 33 are configured as a three-way pipe. The three-way pipe includes a water source interface 321 and at least two connection ports 322. The at least two connection ports 322 are connected to the water source interface 321 and are respectively connected to at least two heating water pipes 31 in a one-to-one correspondence.

[0073] Specifically, the three-way pipe is connected between the heating water pipe 31 and the external water circuit. At least two connection ports 322 of the three-way pipe are respectively connected to the water source interface 321, so that water at the water source interface 321 can flow to the two connection ports 322, and water at the two connection ports 322 can flow to the water source interface 321. The water flow directions of the inlet component 32 and the outlet component 33 are opposite. The inlet component 32 introduces external water into the heating water pipe 31, and the outlet component 33 discharges the water in the heating water pipe 31 out of the heating water pipe 31.

[0074] Among them, such as Figure 1 , Figure 2 , Figure 5 and Figure 11 As shown, the T-connector can be connected to an external water system through the water source interface 321, and can be connected to at least two heating water pipes 31 one-to-one through at least two connection ports 322. The outlet side of the T-connector can be connected to the heating water pipe 31. In this way, water from the external water system flows into the T-connector from the water source interface 321, and flows to one heating water pipe 31 through at least two connection ports 322 to supply water to the heating water pipe 31. The outlet side of the heating water pipe 31 is connected to the external water system through the T-connector, so that water from at least two heating water pipes 31 can flow into the T-connector from at least two connection ports 322, and then flow out from the water source interface 321 to achieve the outlet of the heating water pipe 31.

[0075] Therefore, by setting it as a three-way pipe, the water flow on the inlet side of the heating water pipe 31 can be split, and the water flow on the outlet side of the Xi'an heating water pipe 31 can be merged. The water flow can be concentrated for input and output. The structure is simpler and more convenient. In this embodiment, the three-way pipe is constructed as a Y-shaped pipe, but it can also be constructed as a T-shaped pipe, which are used to change the water flow and guide the flow respectively. The setting method is diverse and can be flexibly selected.

[0076] In some embodiments, at least two connection ports 322 have the same inner diameter, which makes the cross-sectional area of ​​the water flowing through at least two connection ports 322 the same, so that the water flow rate of at least two connection ports 322 is more uniform, thereby improving the flow distribution uniformity of the three-way pipe. Furthermore, at least two connection ports 322 of the three-way pipe are connected to at least two heating water pipes 31 in a one-to-one correspondence, making the water flow rate of each heating water pipe 31 more uniform. This allows each heating water pipe 31 to carry away the heat of the heating component 2 more evenly, improving the heat exchange uniformity between the heating water pipe 31 and the heating component 2, thereby improving the heat exchange performance of the heating device 100.

[0077] In this design, the inner diameters of at least two connection ports 322 can be similar, and the inner diameters of at least two connection ports 322 can be the same as the inner diameter of the corresponding heating water pipes 31. This improves the smoothness and speed of water flow. Furthermore, the inner diameters of at least two connection ports 322 can be set to be less than or equal to the inner diameter of the water source interface 321, which helps to increase the flow rate and speed of water. This configuration also simplifies the overall pipeline structure and makes the layout more uniform. Additionally, the diameters of at least two heating water pipes 31 can be the same, resulting in a mirror-image structure after molding. This ensures that the water resistance of the two heating water pipes 31 is similar, leading to even flow distribution. The two heating water pipes 31 can also be nested together effectively, allowing for more piping to be arranged within a smaller volume, minimizing space waste.

[0078] In some embodiments, the heat conductor 1 is integrally formed on the heating component 2 and the water pipe assembly 3. In actual processing, it can be integrally formed with the heating component 2 and the water pipe assembly 3 by die casting or casting, making the structure of the entire heating device 100 more compact and stable. This allows the heating device 100 to better adapt to various complex environments, such as high temperature, high pressure or corrosive environments. The integral forming allows the heat conductor 1 to fit tightly against the outside of the heating component 2 and the water pipe assembly 3, which helps to transfer heat more effectively from the heating component 2 to the fluid in the water pipe assembly 3, allowing the fluid to reach the required temperature more quickly. This also helps to distribute heat more evenly and has a certain buffer to prevent local overheating or overcooling. This close contact reduces thermal resistance and improves heat transfer efficiency, thereby helping to extend the life of the heating device 100 and improve its overall performance.

[0079] Furthermore, this integrated structure reduces the number of connection points between the heat conductor 1, heating component 2, and water pipe assembly 3, thereby reducing the risk of leakage and failure due to poor or loose connections, and enhancing the stability and reliability of the system. Since the heat conductor 1, heating component 2, and water pipe assembly 3 are already integrally molded, operators do not need to install these components separately, which reduces the need for connecting parts and assembly steps, simplifying the installation process and reducing installation time and costs.

[0080] Furthermore, the heat conductor 1 is also provided with a fixing part for fixing the thermostat, fuse, temperature probe and other protective devices for thermal protection. It can monitor the temperature of the heating device 100 and provide overheat protection for the heating device 100 to improve the safety and reliability of the operation of the heating device 100.

[0081] In some embodiments, the heat conductor 1 is made of aluminum alloy, which has a high thermal conductivity, enabling efficient and rapid heat transfer and dissipation. That is, under the same heating conditions, the aluminum alloy heat conductor 1 can more quickly transfer the heat from the heating component 2 to the fluid in the water pipe assembly 3, thereby improving heating efficiency. Furthermore, the aluminum alloy heat conductor 1 can distribute heat more evenly, preventing localized overheating or undercooling, thus helping to extend the lifespan of the heating device 100 and improve overall performance, while also shortening heating time and saving energy.

[0082] Aluminum alloys have a low density but high strength, which allows the heat conductor 1 to maintain efficient heat conduction while also being lightweight. This helps reduce the overall weight of the heating device 100, facilitating installation and maintenance. Aluminum alloys also have good corrosion resistance, maintaining stable performance under harsh environmental conditions, extending the service life of the heat conductor 1 and reducing maintenance costs.

[0083] Among them, the heat conductor 1 can also be made of materials such as aluminum nitride and ceramics. Some polymer composite materials such as thermally conductive silicone, thermally conductive grease, and thermally conductive gel are also used as materials for the heat conductor 1. The setting methods are diverse and can be flexibly selected according to needs.

[0084] In some embodiments, the heating assembly 2 includes a plurality of parallel, spaced-apart heating tubes 21, which can be evenly spaced apart. This allows for a more uniform heat distribution, resulting in a more uniform temperature within the heating area of ​​the heating assembly 2. This helps to accelerate the heating process and improve heating efficiency. Furthermore, at least two heating water pipes 31 are wrapped around the outside of the plurality of heating tubes 21, allowing for a more even transfer of heat from the heating tubes 21 to the heating water pipes 31. This prevents localized overheating or undercooling of the heating water pipes 31, thereby improving the heating quality.

[0085] Furthermore, the design of multiple heating tubes 21 can increase the redundancy of the heating device 100. Even if one or more heating tubes 21 fail, the other heating tubes 21 can still continue to work, ensuring the normal operation of the heating device 100 and improving the reliability and stability of the heating device 100.

[0086] The heating component 2 can be configured as multiple heating tubes 21 evenly spaced along the horizontal or vertical direction. The overall structure is simple and reliable, and makes the maintenance and replacement of individual heating tubes 21 more convenient. When a heating tube 21 fails, it can be removed and replaced without large-scale disassembly of the entire heating component 2, which can improve maintenance convenience and reduce maintenance costs.

[0087] And such as Figure 2 , Figure 4 , Figure 10 and Figure 11 As shown, there are six heating tubes 21, and the heating tubes 21 can also be set to two, three, four, five, seven, etc.

[0088] This utility model also proposes a water heater.

[0089] According to the embodiments of the present utility model, the water heater is provided with a heating device 100 of any of the above embodiments. For example, the heating device 100 is provided on the hydraulic module of the water heater, and the water inlet component 32 and the water outlet component 33 are connected into the water circuit to heat the water entering the heat pump so as to realize the heating function of the water heater.

[0090] Furthermore, by setting up the heating component 2, water pipe assembly 3 and heat conductor 1 for coordinated use, the heating component 2 can transfer heat to the water pipe assembly 3 through the heat conductor 1, and the heat transfer is uniform and the heating efficiency is high. It can also avoid direct contact between the heating component 2 and the water pipe assembly 3, avoid the heating component 2 from water corrosion and thermal shock, and improve the service life of the heating component 2. This makes the overall structure of the water heater highly reliable, has a good heating effect and high safety.
