The flange is fixed to the condenser housing, and the heat exchange coil is located inside the housing. Both ends of the heat exchange coil extend through the flange to the outside of the housing, forming an inlet and an outlet, respectively. In use, a medium (such as refrigerant) can be introduced into the inlet, passing through the heat exchange coil and exiting from the outlet, thereby achieving heat exchange between the medium and the liquid inside the housing through the heat exchange coil.

[0004] However, the heat exchange components mentioned above have low heat exchange efficiency in actual use. Utility Model Content

[0005] This application provides a heat exchange component and a water heater, which can solve the problem of low heat exchange efficiency of heat exchange components in actual use.

[0014] In one possible implementation, the heat exchange tube is a spiral tube;

[0015] And / or, the outer diameter of the heat exchange tube is less than 9 mm.

[0016] In one possible implementation, at least one support member is also included, which is correspondingly disposed on the heat exchange tube and is used to abut against the mounting part of the heat exchange assembly.

[0017] In one possible implementation, the support is ring-shaped and is fitted onto the heat exchange tube.

[0018] In one possible implementation, a connector is also included, wherein at least one of the inlet pipe and the outlet pipe is connected to the connector, the connector being used to fix the heat exchange assembly to the mounting bracket.

[0019] The liquid outlet and the liquid inlet are located on one side of the connector, and the heat exchange tube is located on the other side of the connector.

[0020] In one possible implementation, the connector is provided with a connecting flange, the connector being fixed to the mounting part of the heat exchange assembly via the connecting flange, the connecting flange being covered with a sealing gasket layer, the sealing gasket layer being used to contact the mounting part of the heat exchange assembly to seal the gap between the connecting flange and the mounting part of the heat exchange assembly.

[0022] This application provides a heat exchange component and a water heater. The heat exchange component includes: an inlet pipe with an inlet; an outlet pipe with an outlet; and multiple heat exchange tubes, one end of which is connected to the inlet pipe, and the other end of which is connected to the outlet pipe. During installation, multiple heat exchange tubes are placed inside a condenser housing, allowing them to simultaneously contact the liquid within the housing, thus increasing the contact area between the heat exchange component and the liquid. During use, a medium (such as refrigerant) is introduced into the inlet pipe, passes through the multiple heat exchange tubes, and then exits through the outlet. This process facilitates heat exchange between the medium and the liquid within the housing, significantly improving heat exchange efficiency.

Detailed Implementation

[0036] 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.

[0037] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0038] 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.

[0039] The heat exchanger is a crucial component of a water heater, typically located on the condenser. In related technologies, the heat exchanger includes a flange and a heat exchange coil. The flange is fixed to the condenser housing, and the heat exchange coil is located inside the housing. Both ends of the heat exchange coil penetrate the flange to the outside of the housing, forming an inlet and an outlet, respectively. During operation, a medium (such as refrigerant) is introduced into the inlet, passes through the heat exchange coil, and exits from the outlet, thus achieving heat exchange between the medium and the liquid inside the housing.

[0040] However, in actual use, the heat exchange components mentioned above only exchange heat with the liquid in the tank through a single heat exchange coil. At this time, the heat exchange efficiency between the heat exchange components and the liquid in the tank is easily affected by the contact area between the heat exchange coil and the liquid in the tank.

[0041] To address the aforementioned problems, this application provides a heat exchange component and a water heater. The heat exchange component includes: an inlet pipe with an inlet port; an outlet pipe with an outlet port; and multiple heat exchange tubes, one end of which is connected to the inlet pipe, and the other end of which is connected to the outlet pipe. During installation, multiple heat exchange tubes are placed within the condenser housing, allowing them to simultaneously contact the liquid within the housing, thus increasing the contact area between the heat exchange component and the liquid. During use, a medium (such as refrigerant) is introduced into the inlet pipe, passes through the multiple heat exchange tubes, and then exits through the outlet port. This process facilitates heat exchange between the medium and the liquid within the housing, significantly improving heat exchange efficiency. Furthermore, within the limited space occupied in the housing, the outer diameter of the heat exchange tubes can be reduced while increasing the number or length of the tubes, thereby increasing the contact area between the heat exchange component and the liquid, further enhancing heat exchange efficiency and solving the problem of low heat exchange efficiency in practical applications.

[0042] Figure 1 This is a schematic diagram of the structure of the heat exchange component provided in the embodiments of this application; Figure 2 for Figure 1 A magnified structural diagram of part A in the middle.

[0043] Combination Figure 1 As shown, this application provides a heat exchange assembly, including:

[0044] The liquid inlet pipe 100 has a liquid inlet 110;

[0045] The liquid outlet pipe 200 has a liquid outlet 210;

[0046] Multiple heat exchange tubes 300 are provided. One end of the heat exchange tube 300 in the extension direction is connected to the liquid inlet pipe 100, and the other end of the heat exchange tube 300 in the extension direction is connected to the liquid outlet pipe 200.

[0047] The heat exchange tube 300 can be made of stainless steel, copper, aluminum, or other materials with good thermal conductivity, and there are no restrictions on the material. Furthermore, there are no restrictions on the specific shape of the heat exchange tube 300.

[0048] During installation, multiple heat exchange tubes 300 can be placed inside the condenser housing, so that multiple heat exchange tubes 300 can simultaneously contact the liquid inside the housing, thereby increasing the contact area between the heat exchange assembly as a whole and the liquid inside the housing.

[0049] In use, a medium (such as refrigerant) is introduced into the inlet pipe 100 through the inlet port 110, passes through multiple heat exchange tubes 300, and is then discharged from the outlet port 210. This process facilitates heat exchange between the medium and the liquid inside the tank via the multiple heat exchange tubes 300, significantly improving heat exchange efficiency and solving the problem of low heat exchange efficiency in actual use of heat exchange components.

[0050] Furthermore, the liquid inlet pipe 100 is connected to at least two liquid inlet branch pipes 120, and one end of the heat exchange tube 300 in the extension direction is correspondingly connected to the liquid inlet branch pipe 120.

[0051] And / or, the liquid outlet pipe 200 is connected to at least two liquid outlet branch pipes 220, and the other end of the heat exchange tube 300 in the extension direction is correspondingly connected to the liquid outlet branch pipe 220.

[0052] In this embodiment, the inlet pipe 100 is connected to two inlet branch pipes 120, and the outlet pipe 200 is connected to two outlet branch pipes 220. The two ends of the heat exchange tube 300 in the extension direction are respectively connected to any one of the inlet branch pipes 120 and any one of the outlet branch pipes 220.

[0053] It should be noted that the connection between the inlet branch pipe 120 and the inlet pipe 100, the connection between the outlet branch pipe 220 and the outlet pipe 200, and the connection between the heat exchange tube 300 and the inlet branch pipe 120 or the outlet branch pipe 220 can all be achieved by welding, flange or threaded connection.

[0054] Therefore, the heat exchange tube 300 can be connected to the inlet pipe 100 or the outlet pipe 200 via the inlet branch pipe 120 or the outlet branch pipe 220. In use, a medium (such as refrigerant) is introduced into the inlet pipe 100 through the inlet port 110. After being diverted by the inlet branch pipe 120, the medium enters multiple heat exchange tubes 300, and then flows sequentially through the outlet branch pipe 220 and the outlet pipe 200 before being discharged from the outlet port 210.

[0055] Based on this, the outer diameter of the heat exchange tube 300 can be reduced within the limited space occupied in the box, while the number or length of the heat exchange tube 300 can be increased, thereby increasing the contact area between the heat exchange components and the liquid in the box, and thus improving the heat exchange efficiency.

[0056] In other embodiments, the number of inlet branch pipes 120 and outlet branch pipes 220 can be reasonably set according to actual needs, such as three, four or other numbers. Of course, only inlet branch pipes 120 or outlet branch pipes 220 can be set.

[0057] It should be noted that this heat exchange component can also be used in other heat exchange systems. In this case, the medium flowing inside the heat exchange tube 300 can be reasonably selected according to actual needs, such as cold water or hot water.

[0058] In the prior art, the outer diameter of the heat exchanger coil is typically 9.5 mm. In this embodiment, the outer diameter of the heat exchanger tube 300 can be set to less than 9 mm according to actual needs. For example, the diameter of the heat exchanger tube 300 can be set to 9 mm, 8 mm, 7.5 mm, 7 mm, 6.5 mm, 6 mm, etc. Furthermore, the wall thickness is not limited.

[0059] With the same internal space occupied, the larger the contact area between the heat exchange assembly and the liquid inside the tank, the higher the heat exchange efficiency. In the prior art, the surface area S1 of the heat exchange coil (calculated as a long straight cylinder) is S1 = 9.5 * π * L1, where L1 is the length of the heat exchange coil. In this embodiment, taking a heat exchange tube 300 with a diameter of 8 mm as an example, while ensuring the same internal space, i.e., π * 4.75... 2 *L1=π*4 2 *L2, where L2 is the length of heat exchange tube 300. Calculation shows that the surface area of ​​heat exchange tube 300 is S2=8*π*L2=11.3*π*L1. Therefore, S2>S1.

[0060] In other words, given the same amount of space occupied inside the housing, the smaller diameter heat exchange tube 300 has a relatively larger surface area, resulting in a larger heat exchange area and higher heat exchange efficiency.

[0061] Therefore, while occupying the same internal space within the chamber, the diameter of the heat exchange tubes 300 can be appropriately reduced according to actual needs, while the length of each individual heat exchange tube 300 can be increased accordingly. This increases the total length of the heat exchange tubes 300, thereby increasing the overall surface area of ​​the multiple heat exchange tubes 300, increasing the contact area between the heat exchange components and the liquid inside the chamber, and thus increasing heat exchange efficiency. Alternatively, the total length of the heat exchange tubes 300 can also be increased by increasing the number of heat exchange tubes 300.

[0062] Furthermore, in some scenarios, while maintaining the same total length and wall thickness of the heat exchange tube 300, the outer diameter of the heat exchange tube 300 can be appropriately reduced, resulting in a relatively smaller inner diameter and thus a smaller internal volume. Consequently, in actual heat exchange system applications, the flow rate of the liquid pumped into the heat exchange tube 300 can be reduced, while maintaining an appropriate flow velocity, thereby lowering the system's internal resistance, reducing system pressure drop, and lowering system energy consumption.

[0063] Combination Figure 1 As shown, in some embodiments, the heat exchange assembly further includes a connector 400, at least one of the inlet pipe 100 and the outlet pipe 200 being connected to the connector 400, the connector 400 being used to fix it to the mounting part of the heat exchange assembly;

[0064] The liquid outlet 210 and the liquid inlet 110 are located on one side of the connector 400, and the heat exchange tube 300 is located on the other side of the connector 400.

[0065] The connector 400 can be block-shaped, column-shaped, plate-shaped, or other shapes, and there are no restrictions on this.

[0066] In this embodiment, both the inlet pipe 100 and the outlet pipe 200 can be fixed to the connector 400 by welding, screwing, bonding or other means.

[0067] Specifically, the inlet pipe 100 passes through the connector 400, such that the two ends of the inlet pipe 100 in the extension direction are located on opposite sides of the connector 400, that is, the inlet port 110 and the inlet branch pipe 120 are located on opposite sides of the connector 400.

[0068] The outlet pipe 200 also passes through the connector 400, and the two ends of the outlet pipe 200 in the extension direction are located on opposite sides of the connector 400, that is, the outlet 210 and the outlet branch pipe 220 are located on opposite sides of the connector 400.

[0069] Furthermore, the inlet 110 and outlet 210 are located on the same side of the connector 400, and each inlet branch pipe 120 and each outlet branch pipe 220 are located on the same side of the connector 400. That is to say, the heat exchange tube 300 will be located on the other side of the connector 400 relative to the inlet 110 and outlet 210.

[0070] In practice, the heat exchange tubes 300, inlet pipe 100, outlet pipe 200, inlet branch pipe 120, and outlet branch pipe 220 can be installed simply by welding, screwing, or otherwise fixing the connector 400 to the housing within the condenser. This ensures that the heat exchange tubes 300 are located inside the housing, while the inlet 110 and outlet 210 are located outside. This makes the installation of the heat exchange components relatively convenient.

[0071] It should be noted that this embodiment uses the application of a heat exchange component in a condenser as an example, and the housing in the condenser is the mounting component of the heat exchange component. Of course, when applied to other equipment, the components on other equipment used to connect to the connector 400 are the mounting components of the heat exchange component.

[0072] Combination Figure 1 As shown, in some embodiments, multiple heat exchange tubes 300 are evenly distributed along the extension direction of the liquid inlet pipe 100.

[0073] The extension direction of each inlet branch pipe 120 is parallel to the extension direction of each outlet branch pipe 220.

[0074] In this embodiment, the two inlet branch pipes 120 are parallel to each other and extend horizontally, and the two outlet branch pipes 220 are parallel to each other and extend horizontally, so that the extension direction of each inlet branch pipe 120 and the extension direction of each outlet branch pipe 220 are parallel to each other, thereby reducing the possibility of interference between each inlet branch pipe 120, each outlet branch pipe 220 and the heat exchange tube 300.

[0075] Multiple heat exchange tubes 300 are evenly distributed in the horizontal direction. Therefore, after installing multiple heat exchange tubes 300 in the condenser housing, the multiple heat exchange tubes 300 can be evenly arranged in the housing to improve the temperature field distribution of the heat exchange components and improve the heat exchange performance.

[0076] In other embodiments, the extension directions of each outlet branch pipe 220 or the extension directions of each inlet branch pipe 120 may be parallel to each other.

[0077] Furthermore, the heat exchange tube 300 is a spiral tube. In this embodiment, the spiral direction of the heat exchange tube 300 is horizontal, that is, consistent with the extension direction of the liquid inlet pipe 100. This allows for an increase in the length of the heat exchange tube 300 within a limited space, thereby increasing the contact area between the heat exchange tube 300 and the liquid inside the condenser, and optimizing the heat exchange effect.

[0078] In other embodiments, the spiral direction of the heat exchange tube 300 may also be along other directions, such as vertical or oblique.

[0079] Combination Figure 1 As shown, in some embodiments, at least one support member 500 is also included, which is correspondingly disposed on the heat exchange tube 300 and is used to abut against the mounting part of the heat exchange assembly.

[0080] It should be noted that in actual applications, after multiple heat exchange tubes 300 are installed in the condenser housing, they are only fixed to the housing by the connector 400 on one side. The multiple heat exchange tubes 300 are prone to sag due to their own weight, and the sag is more obvious the further away from the connector 400.

[0081] Based on this, at least one support member 500 is used and correspondingly installed on the heat exchange tube 300, with the support member 500 abutting against the inner wall of the housing below the heat exchange tube 300. This supports the heat exchange tube 300, further improving its stability after installation. Furthermore, it reduces the possibility of the heat exchange tube 300 directly colliding with the housing during installation, optimizing the safety of the heat exchange tube 300 during installation and use.

[0082] Combination Figure 1 As shown, in some embodiments, the support 500 is annular and is correspondingly sleeved on the heat exchange tube 300.

[0083] In this embodiment, each liquid inlet branch pipe 120 and each liquid outlet branch pipe 220 are located inside the heat exchange tube 300, thereby ensuring that the liquid inlet branch pipe 120 and the liquid outlet branch pipe 220 do not easily come into direct contact with the condenser housing.

[0084] The support member 500 is annular and can be made of silicone or rubber. Each support member 500 is respectively fitted onto each heat exchange tube 300. In this embodiment, two support members 500 are provided for the same heat exchange tube 300, and the two support members 500 are fitted onto the two ends of the heat exchange tube 300 along its own spiral direction. The lower surface of the support member 500 abuts against the inner wall of the housing below the heat exchange tube 300. This improves the stability of the heat exchange tube 300 after installation and optimizes the safety of the heat exchange tube 300 during installation and use.

[0085] Furthermore, the support component 500 can be easily installed by simply fitting it onto the heat exchange tube 300.

[0086] In other embodiments, the support member 500 may also be a support block, support column, bracket or support pad connected to the heat exchange tube 300, and its specific shape is not limited.

[0087] Combination Figure 1 and Figure 2 As shown, in some embodiments, the connector 400 is provided with a connecting flange 410, and the connector 400 is used to be fixed to the mounting part of the heat exchange assembly through the connecting flange 410; the connecting flange 410 is covered with a sealing gasket 420, and the sealing gasket 420 is used to contact the mounting part of the heat exchange assembly to seal the gap between the connecting flange 410 and the mounting part of the heat exchange assembly.

[0088] The connecting flange 410 can be connected to the connector 400 by welding, integral molding, bonding or other means. The connecting flange 410 has multiple through holes, which allow bolts or screws to pass through during installation to secure the connecting flange 410 to the condenser housing.

[0089] The sealing gasket 420 can be made of silicone or rubber and wraps around the connecting flange 410. This allows the sealing gasket 420 to seal the gap between the connecting flange 410 and the mounting parts of the heat exchange assembly after the connecting flange 410 is fastened to the condenser housing, reducing the possibility of liquid leakage from this gap and optimizing the installation effect of the connector 400.

[0090] Combination Figure 1 and Figure 2 As shown, in some embodiments, the heat exchange assembly further includes a temperature measuring element 600, which is used to detect the temperature outside the heat exchange tube 300. The temperature measuring element 600 has a terminal 610, and the terminal 610 is detachably provided with a first protective element 700, which wraps around the terminal 610.

[0091] And / or, the heat exchange assembly further includes at least one second protective element 800, which is provided on the inlet pipe 100 or the outlet pipe 200 to block the inlet port 110 or the outlet port 210 respectively.

[0092] In this embodiment, the temperature sensing element 600 can be a temperature sensing tube, and the model is not limited. Furthermore, one end of the temperature sensing element 600 extending in the direction of extension is the detection end, and the other end extending in the direction of extension is the wiring terminal 610 for connection to an external circuit.

[0093] The temperature sensing element 600 can be fixed to the connector 400 by bonding, snapping, screwing, or other means, so that the two opposite ends of the temperature sensing element 600 are located on opposite sides of the connector 400. That is, the detection end on the temperature sensing element 600 is located on the same side of the connector 400 corresponding to the heat exchange tube 300, and the wiring end 610 on the temperature sensing element 600 is located on the same side of the connector 400 corresponding to the liquid inlet 110 or the liquid outlet 210.

[0094] During installation, after the connector 400 is fixed to the water heater tank, the detection end of the temperature sensor 600 can be located inside the tank, so that the temperature of the area inside the tank (outside the heat exchange tube 300) can be detected by the temperature sensor 600.

[0095] In other embodiments, the temperature measuring element 600 may also be an existing product used for temperature detection, such as a thermometer or temperature sensor.

[0096] The terminal 610 is detachably provided with a first protective element 700, which encloses the terminal 610. The first protective element 700 can be a protective cap, which can be connected to the terminal 610 by screwing, snapping, or other means.

[0097] During installation, after the external line is connected to the terminal 610, the first protective component 700 can be fixed to the terminal 610 to cover the part of the terminal 610 connected to the external line, thereby providing a certain degree of protection for the connection part, reducing the possibility of external moisture directly contacting the connection part, and improving the safety during use.

[0098] In addition, the first protective component 700 can clamp the external line to the terminal 610 to improve the stability of the connection between the external cable and the terminal 610.

[0099] Combination Figure 2 As shown, in this embodiment, the second protective member 800 can be a block or columnar plug. The second protective member 800 is used to be inserted into the liquid inlet 110 or the liquid outlet 210, so that the second protective member 800 is interference-fitted with the liquid inlet pipe 100 or the liquid outlet pipe 200.

[0100] Therefore, before installation, the inlet 110 or outlet 210 can be protected by the second protective component 800, reducing the possibility of external debris entering.

[0101] In practice, a second protective element 800 can be installed on both the inlet 110 and the outlet 210. Alternatively, only one second protective element 800 (e.g., two plugs connected to each other) can be installed, so that the second protective element 800 simultaneously blocks both the inlet 110 and the outlet 210.

[0102] In other embodiments, the second protective member 800 may also be a protective cover, which is connected to the inlet pipe 100 or the outlet pipe 200 to cover the inlet port 110 or the outlet port 210 respectively.

[0103] Both the first protective component 700 and the second protective component 800 can be made of PA (polyamide), silicone, or rubber.

[0104] In summary, the heat exchange assembly provided in this application allows multiple heat exchange tubes 300 to be placed inside the condenser housing during installation, ensuring that all heat exchange tubes 300 are simultaneously in contact with the liquid inside the housing, thereby increasing the overall contact area between the heat exchange assembly and the liquid inside the housing. During use, a medium (such as refrigerant) is introduced into the inlet pipe 100 through the inlet port 110. After being diverted through the inlet branch pipe 120, the medium enters the multiple heat exchange tubes 300, then sequentially passes through the outlet branch pipe 220 and the outlet pipe 200, and finally exits from the outlet port 210. This achieves heat exchange between the medium and the liquid inside the housing through the multiple heat exchange tubes 300, significantly improving heat exchange efficiency and solving the problem of low heat exchange efficiency in practical applications.

[0105] This application provides a water heater, such as a solar heat pump water heater, an electric water heater, a gas water heater, etc., including a housing and a heat exchange component in any of the above embodiments, wherein the heat exchange tube 300 in the heat exchange component is disposed in the housing.

[0106] Specifically, the water heater includes a condenser, which includes a housing and a heat exchange assembly as described in any of the above embodiments. The heat exchange tubes 300 in the heat exchange assembly are disposed within the housing. The specific structure of the heat exchange assembly has been described in detail in the above embodiments and will not be repeated here.

[0107] In addition, water heaters also include multiple components, such as compressors, evaporators, expansion valves, and water tanks, which can be configured according to the structure of existing water heater products without limitation.

[0108] During implementation, simply fasten the connector 400 in the heat exchange assembly to the housing (not shown in the figure) to complete the installation of the heat exchange tube 300, liquid inlet pipe 100, liquid outlet pipe 200, liquid inlet branch pipe 120, and liquid outlet branch pipe 220 on the condenser. Ensure that each heat exchange tube 300 is located inside the housing, and that the liquid inlet 110 and liquid outlet 210 are located outside the housing.

[0109] In summary, the water heater provided in this application allows a medium (such as refrigerant) to be introduced into the inlet pipe 100 through the inlet port 110 during use. The medium then passes through the heat exchange tubes 300 and is discharged from the outlet port 210 on the outlet pipe 200. This achieves heat exchange between the medium and the liquid inside the tank through multiple heat exchange tubes 300, significantly improving heat exchange efficiency and solving the problem of low heat exchange efficiency in actual use of heat exchange components.

[0110] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings.
