Technical Field

[0002] With the development of automotive technology, the functions of automotive thermal management systems are becoming increasingly complex, and the requirements for integration are constantly increasing. Thermal management systems generally integrate heating devices. In order to improve assembly efficiency, it is desirable for the heating devices to be able to be quickly assembled with the pipelines in the thermal management system through a quick-connect structure. However, the port of the heating device is usually made by extrusion molding, and its shape is cylindrical with a thin wall, making it difficult to form a structure that can be adapted to the quick-connect structure. This makes it impossible to achieve quick assembly with the pipelines, and the assembly reliability is not high, and it is easy to loosen in the vibrating environment. Summary of the Invention

[0019] In one embodiment, each of the adapters is provided independently of the other; or, at least two of the adapters are connected to each other.

[0020] In one embodiment, at least two of the adapters include a first adapter and a second adapter that are separately configured.

[0021] In one embodiment, the housing includes a housing body and a cover plate. The housing body and the cover plate surround a receiving cavity for accommodating the heater.

The lead-out component can be integrated into the external pipeline or be part of the heating device. Since the adapter and lead-out component are independent of the port, their materials and manufacturing processes are not constrained by the port, allowing the adapter to be constructed as a quick-connect joint suitable for the lead-out component. Thus, through the bridging effect of the adapter and lead-out component, rapid assembly of the heating device with the external pipeline is achieved. Furthermore, the sleeve of the adapter is equipped with an anti-detachment part. When the adapter and lead-out component are assembled in place, the anti-detachment part at least partially extends into the lead-out component, forming a tight fit with the inner wall surface of the lead-out component. This prevents the lead-out component from axially loosening relative to the sleeve under vibration conditions, improving assembly reliability, preventing loosening, and reducing the risk of fluid leakage.

[0034] With the development of automotive technology, the functions of automotive thermal management systems are becoming increasingly complex, and the requirements for integration are constantly increasing. Thermal management systems generally integrate heating devices. In order to improve assembly efficiency, it is desirable for the heating devices to be able to be quickly assembled with the pipelines in the thermal management system through a quick-connect structure. However, the port of the heating device is usually made by extrusion molding, and its shape is cylindrical with a thin wall, making it difficult to form a structure that can be adapted to the quick-connect structure. This makes it impossible to achieve quick assembly with the pipelines, and the assembly reliability is not high, and it is easy to loosen in the vibrating environment.

[0035] Based on this, this application proposes a heating device 100 that enables rapid assembly between the heating device 100 and the pipeline, improves assembly reliability, and prevents loosening under vibration.

[0036] For ease of understanding and explanation, the specification of this application is attached. Figures 1 to 20 In the diagram, solid arrows indicate spaces, slots, or holes.

[0037] Please see Figures 1 to 5 The heating device 100 provided in one embodiment of this application includes a device body 10 and an adapter 20. The device body 10 has a fluid channel 101 and a port portion 121, with the flow port 1011 of the fluid channel 101 located at the port portion 121. The adapter 20 is used to connect the port portion 121 to an external pipeline outlet 30. The adapter 20 includes a sleeve 21 and an anti-detachment portion 223 located on the sleeve 21. The sleeve 21 is fitted onto the port portion 121, and the outlet 30 is fitted onto the sleeve 21. The anti-detachment portion 223 extends at least partially into the outlet 30 and is used to limit the outlet 30 from axially loosening relative to the adapter 20.

[0038] The main body 10 of the device serves as the main structure of the heating device 100, providing a fluid channel 101. The main body 10 also heats the fluid (e.g., liquid) within the fluid channel 101. For example, when the heating device 100 is connected to the piping of a thermal management system, the heat exchange medium within the fluid channel 101 can be heated by the heating device 100 and transported to other components requiring heat exchange via the piping of the thermal management system. The heating device 100 has a port portion 121, where a flow channel port 1011 of the fluid channel 101 is located. For example, the flow channel port 1011 of the fluid channel 101 typically includes a fluid inlet (e.g., a liquid inlet) and a fluid outlet (e.g., a liquid outlet). Accordingly, the heating device 100 has at least two port portions 121, one of which has a fluid inlet and the other has a fluid outlet.

[0039] The function of the adapter 20 is to bridge the main body 10 of the device and the lead-out member 30, enabling them to be mechanically connected. It is worth noting that in this embodiment, the lead-out member 30 can be a plug structure that comes with the external pipeline. For example, the lead-out member 30 is a female connector and the adapter 20 is a male connector. The adapter 20 and the lead-out member 30 can be quickly assembled.

[0040] The adapter 20 includes a sleeve 21 and an anti-detachment part 223 disposed on the sleeve 21. The sleeve 21 is cylindrical with both ends open, allowing it to be fitted around the periphery of the port portion 121. The sleeve 21 and the port portion 121 are connected by means including, but not limited to, interference fits and snap-fits to limit the axial movement of the sleeve 21 relative to the port portion 121. The sleeve 21 is provided with the anti-detachment part 223. When the lead-out member 30 is fitted onto the outer periphery of the sleeve 21, the anti-detachment part 223 extends at least partially into the lead-out member 30. The anti-detachment part 223 and the lead-out member 30 are engaged to limit the axial loosening of the lead-out member 30 relative to the adapter 20. The limiting fit between the anti-detachment part 223 and the lead-out member 30 includes, but is not limited to, interference fits and snap-fits. For example, the anti-detachment part 223 can be pressed against the inner wall of the lead-out part 30 to form an interference fit, thereby achieving the anti-detachment function; or the anti-detachment part 223 can be constructed as a hook-like structure, and the anti-detachment function can be achieved by engaging with the protrusions or grooves on the inner wall of the lead-out part 30. For example, the adapter 20 may include a cylindrical body and an anti-detachment claw 22 provided on the cylindrical body. The anti-detachment claw 22 has an anti-detachment part 223 and a snap-fit ​​part 222. The cylindrical body is sleeved around the port part 121, and the snap-fit ​​part 222 of the anti-detachment claw 22 engages with the port part 121, so that the adapter 20 can be stably installed on the port part 121. Furthermore, when the lead-out member 30 is fitted around the adapter 20, the anti-detachment portion 223 of the anti-detachment claw 22 can at least partially extend into the lead-out member 30. The anti-detachment portion 223 forms a tight fit with the inner wall surface of the lead-out member 30, making the assembly of the lead-out member 30 and the adapter 20 more stable and reliable. The number of anti-detachment portions 223 can be designed as one or more according to actual needs. Optionally, multiple anti-detachment portions 223 are provided, arranged circumferentially along the cylinder body, to further enhance the anti-detachment function and improve assembly stability.

[0041] The technical solution of this application involves providing an adapter 20 at the port 121 of the main body 10 of the device, using the adapter 20 to connect the port 121 to the lead-out member 30 of the external pipeline, thereby enabling the fluid channel 101 of the main body 10 to communicate with the external pipeline via the lead-out member 30. Since the adapter 20 is independent of the port 121, the material and manufacturing process of the adapter 20 are not constrained by the port 121, allowing the adapter 20 to be constructed as a connector structure suitable for quick insertion with the lead-out member 30 of the external pipeline. Thus, through the bridging effect of the adapter 20 and the lead-out member 30, rapid assembly of the heating device 100 with the external pipeline can be achieved. Furthermore, the sleeve 21 of the adapter 20 is provided with an anti-detachment part 223. When the adapter 20 and the lead-out part 30 are assembled in place, the anti-detachment part 223 extends into the lead-out part 30 at least partially. The anti-detachment part 223 forms a tight fit with the inner wall surface of the lead-out part 30, which can prevent the lead-out part 30 from loosening relative to the sleeve 21 in the axial direction under vibration environment. This can improve assembly reliability, prevent loosening, and reduce the risk of fluid leakage.

[0042] Please see Figures 1 to 5 The heating device 100 provided in one embodiment of this application includes a device body 10, an adapter 20, and an outlet 30. The device body 10 has a fluid channel 101 and a port portion 121, with the flow port 1011 of the fluid channel 101 located at the port portion 121; the adapter 20 includes a sleeve 21 and an anti-detachment portion 223 located on the sleeve 21, with the sleeve 21 fitted onto the port portion 121; one end of the outlet 30 is fitted onto the adapter 20, and the other end is configured to be connected to an external pipeline, with the outlet 30 having a flow channel 301 that connects the fluid channel 101 to the external pipeline; the anti-detachment portion 223 of the adapter 20 extends at least partially into the outlet 30, and the anti-detachment portion 223 and the outlet 30 are mutually restrictive to prevent the outlet 30 from axially detaching from the adapter 20.

[0043] The main body 10 and adapter 20 in this embodiment are similar to those in the previous embodiments, and can be referred to the description in the previous embodiments, which will not be repeated here. The difference between this embodiment and the previous embodiments is that in the previous embodiments, the lead-out member 30 was a connector structure built into the external pipeline, while in this embodiment, the lead-out member 30 is part of the heating device 100. That is, the heating device 100 has the lead-out member 30 built in, and when it needs to be connected to an external pipeline, it is only necessary to connect the lead-out member 30 to the external pipeline. In this way, the adaptability to external pipelines is higher, and it is suitable for connecting to external pipelines that do not have their own connectors.

[0044] like Figure 10 and Figure 11As shown, the lead-out part 30 may include a plug-in part 31 and a lead-out part 32. The end of the plug-in part 31 away from the lead-out part 32 forms a plug-in interface 311 for insertion of the port part 121, and the end of the lead-out part 32 away from the plug-in part 31 forms an outlet 302 for connecting to an external pipeline. Through the plug-in engagement of the plug-in part 31 and the port part 121, quick-connect assembly of the adapter 20 and the lead-out part 30 can be achieved. The lead-out part 32 extends the liquid flow path, so that the end of the lead-out part 32 away from the plug-in part 31 is as far away from the housing 11 and the heater 12 as possible. Thus, when the end of the lead-out part 32 away from the plug-in part 31 is connected to an external pipeline, interference from the housing 11 and the heater 12 on the installation of the external pipeline can be avoided, reducing the difficulty of installing the external pipeline. The end of the lead-out part 32 away from the plug-in part 31 may be provided with a connecting part suitable for connection to an external pipeline. For example, the connecting part may be a upset head structure protruding from the outer peripheral surface of the lead-out part 32. For example, the connector may be configured as a male connector for insertion into a female connector of an external pipeline. Or, for another example, the connector may be configured as a female connector for fitting over a male connector of an external pipeline.

[0045] The technical solution of this application involves providing an adapter 20 at the port 121 of the device body 10 and an outlet 30 around the adapter 20. The adapter 20 and outlet 30 connect the port 121 to an external pipeline, allowing the fluid channel 101 of the device body 10 to communicate with the external pipeline via the flow channel 301 of the outlet 30. Since the adapter 20, outlet 30, and port 121 of the device body 10 are independent of each other, the material and manufacturing process of the adapter 20 and outlet 30 are not constrained by the port 121. This allows the adapter 20 and outlet 30 to be constructed as quick-connect fittings; for example, the adapter 20 can be constructed as a male connector and the outlet 30 as a female connector, enabling quick connection and assembly. Simultaneously, the outlet 30 is designed for connection to an external pipeline. Thus, through the bridging effect of the adapter 20 and the lead-out member 30, the heating device 100 can be quickly assembled with the external pipeline. Furthermore, the sleeve 21 of the adapter 20 is provided with an anti-detachment part 223. When the adapter 20 and the lead-out member 30 are assembled in place, the anti-detachment part 223 extends at least partially into the lead-out member 30. The anti-detachment part 223 forms a tight fit with the inner wall surface of the lead-out member 30, preventing the lead-out member 30 from axially detaching from the sleeve 21 under vibration conditions. This improves assembly reliability, prevents detachment, and reduces the risk of fluid leakage.

[0046] Based on the two embodiments described above, further improvements to the heating device 100 will be described in detail below.

[0047] To further improve the assembly reliability of the adapter 20 and the lead-out member 30 and enhance the anti-loosening function, in some embodiments, the anti-loosening part 223 extends into the lead-out member 30 with a length of not less than 1 mm in the axial direction of the sleeve 21; and / or, multiple anti-loosening parts 223 are provided, and the multiple anti-loosening parts 223 are arranged circumferentially along the sleeve 21.

[0048] In the axial direction of the sleeve 21, the anti-detachment part 223 extends into the lead-out member 30 by a length of not less than 1 mm. This ensures that the contact length between the anti-detachment part 223 and the inner wall of the lead-out member 30 along the axial direction of the sleeve 21 is not too short, guaranteeing a large contact area between them. This ensures a stable and reliable tight fit between the anti-detachment part 223 and the inner wall of the lead-out member 30, further improving the assembly reliability of the lead-out member 30 and the adapter 20. Furthermore, the length of the anti-detachment part 223 extending into the lead-out member 30 is not too short, preventing it from detaching from the lead-out member 30 and failing in a vibrating environment.

[0049] like Figure 5 As shown, the length of the anti-detachment part 223 extending into the lead-out member 30 along the axial direction of the sleeve 21 refers to the distance H between the end face of the anti-detachment part 223 facing the second port 212 of the sleeve 21 and the end face of the insertion interface 311 of the lead-out member 30 along the axial direction of the sleeve 21. That is, H ≥ 1mm. For example, H can be 1mm, 2mm, 3mm, etc. The maximum length of the anti-detachment part 223 extending into the lead-out member 30 can be adjusted according to the size of the insertion part 31 of the lead-out member 30, and is not specifically limited here.

[0050] like Figures 6 to 8 As shown, multiple anti-detachment parts 223 are provided, arranged circumferentially along the sleeve 21. This allows each anti-detachment part 223 to form a limiting structure with the inner wall of the lead-out member 30, thereby creating multiple anti-detachment points on the circumferential surface of the lead-out member 30. The multiple circumferential anti-detachment parts 223 distribute the total anti-detachment force across the entire circumference. Each anti-detachment part 223 bears only a portion of the force, significantly reducing the load on individual components, thereby significantly improving the overall anti-detachment capability and reliability, and avoiding the risk of "single-point failure".

[0051] In order to significantly improve the overall anti-detachment capability and reliability, optionally, multiple anti-detachment parts 223 are provided at intervals along the circumference of the sleeve 21, and the length of each anti-detachment part 223 extending into the lead-out member 30 in the axial direction of the sleeve 21 is not less than 1 mm.

[0052] like Figures 6 to 8As shown, in some embodiments, the adapter 20 further includes an anti-detachment claw 22 disposed on the sleeve 21, which engages with the port portion 121. By engaging the anti-detachment claw 22 with the port portion 121, the assembly stability of the adapter 20 and the port portion 121 can be further improved, preventing the adapter 20 from becoming loose relative to the port portion 121 under vibration.

[0053] The anti-detachment claw 22 can be integrally formed with the sleeve 21, or the anti-detachment claw 22 can be assembled and connected to the sleeve 21 by welding, bonding, snap-fitting, or other methods. Optionally, the sleeve 21 and the anti-detachment claw 22 can be integrally formed, which can simplify the manufacturing process and ensure the connection strength. For example, the anti-detachment claw 22 and the sleeve 21 can be integrally injection molded. The number of anti-detachment claws 22 can be single or multiple. To ensure the reliability of anti-detachment, multiple (i.e., at least two) anti-detachment claws 22 are provided, and the multiple anti-detachment claws 22 are arranged circumferentially along the sleeve 21. The anti-detachment part 223 can be constructed as part of the anti-detachment claw 22, or the anti-detachment part 223 and the anti-detachment claw 22 can be independent of each other. Optionally, the anti-detachment part 223 is integrally formed with the anti-detachment claw 22.

[0054] Furthermore, in one embodiment, the outer peripheral wall of the port portion 121 is provided with a mating portion 122, and the sleeve 21 has a first port 211 and a second port 212 that are axially opposite each other. The sleeve 21 is sleeved around the port portion 121 from the first port 211. The peripheral wall of the sleeve 21 is provided with an opening 213 that penetrates both sides of the thickness. The anti-detachment claw 22 includes an elastic arm 221 and a snap-fit ​​portion 222 provided in the elastic arm 221. The elastic arm 221 is provided in the opening 213 and connected to the sleeve 21. The snap-fit ​​portion 222 snaps into the mating portion 122.

[0055] In this embodiment, the sleeve 21 has a first port 211 and a second port 212 that are axially opposite each other. The sleeve 21 is fitted around the port portion 121 from the first port 211. That is, the first port 211 is the insertion port for the port portion 121 to be inserted into the sleeve 21. The peripheral wall of the sleeve 21 is provided with an opening 213 that penetrates the inner and outer peripheral walls of the sleeve 21. By providing the opening 213, an installation space and deformation space are provided for the anti-detachment claw 22. Since the opening 213 penetrates both sides of the thickness of the sleeve 21, the anti-detachment claw 22 is installed in the opening 213. When the port portion 121, the adapter 20, and the lead-out member 30 are assembled in place, the inner side of the anti-detachment claw 22 can contact the outer wall of the port portion 121 and form a limiting fit structure, and the outer side of the anti-detachment claw 22 can contact the inner wall of the lead-out member 30 and form a fit structure. The anti-detachment claw 22 includes an elastic arm 221 and a locking portion 222 provided on the elastic arm 221. One end of the elastic arm 221 can be connected to one side edge of the opening 213, and the other end of the elastic arm 221 and both sides of the elastic arm 221 in the width direction are spaced apart from the side edge of the opening 213, thereby enabling the elastic arm 221 to have a greater degree of freedom of elastic deformation. The locking portion 222 can be a groove or protrusion provided on the elastic arm 221 to form a limiting fit with a protrusion or groove provided on the outer peripheral wall of the port portion 121. For example, the outer peripheral wall of the port portion 121 is provided with a mating portion 122, which can be a protrusion protruding towards the outside of the port portion 121 or a recessed portion recessed towards the inside of the port portion 122. The locking portion 222 can be a locking protrusion provided on the side of the elastic arm 221 facing the outer peripheral wall of the port portion 121. For example, the mating part 122 is a protrusion on the outer peripheral wall of the port part 121. During the assembly of the sleeve 21 from the first port 211 to the port part 121, the snap-fit ​​part 222 first abuts against the mating part 122 on the outer periphery of the port part 121 on the side facing the first port 211. By applying a certain external force, the elastic arm 221 can be deformed and expanded outward, so that the snap-fit ​​part 222 can continue to move past the mating part 122. After the sleeve 21 and the port part 121 are assembled in place, the snap-fit ​​part 222 is held in place on the side of the mating part 122 near the first port 211, so that it can form an axial limit with the mating part 122, preventing the adapter 20 from moving away from the port part 121 and loosening, thus improving the assembly reliability. For example, the mating part 122 is a recess on the outer peripheral wall of the port part 121. When the adapter 20 is assembled with the port part 121, the locking part 222 is locked in the recess on the outer peripheral wall of the port part 121, thereby forming an axial limit with the mating part 122. The number of anti-disengagement claws 22 can be one, two, three, four or more.

[0056] To further improve the assembly reliability of the port section 121 and the adapter 20, optionally, multiple anti-disengagement claws 22 are provided, arranged circumferentially along the sleeve 21, and engaging with the mating part 122. This ensures that multiple anti-disengagement claws 22 engage with the mating part 122 in the circumferential direction of the sleeve 21, forming multiple clamping force-bearing points. This makes the force on the adapter 20 more balanced in the circumferential direction. By optimizing the locking force from a single point to a multi-point load, a synergistic enhancement effect is generated, significantly improving the mechanical strength, vibration resistance, and reliability of the connection, effectively preventing loosening and leakage. Secondly, the multi-point elastic clamping achieves automatic centering of the connecting components, compensating for manufacturing and assembly tolerances, ensuring uniform pressing of the sealing surface, and greatly improving the reliability of the seal. Furthermore, while maintaining the advantages of rapid clamping operation, the reasonable distribution of force reduces the performance requirements of individual parts.

[0057] When multiple anti-detachment claws 22 are provided, in order to adapt to multiple anti-detachment claws 22, multiple mating parts 122 are further provided. The multiple mating parts 122 are arranged circumferentially along the port part 121, and the anti-detachment claws 22 are engaged with the mating parts 122 one-to-one; or, the mating parts 122 are arranged in a ring shape extending circumferentially along the port part 121, and the multiple anti-detachment claws 22 are engaged with the mating parts 122 respectively.

[0058] For example, in one embodiment, multiple mating parts 122 are provided, and the multiple mating parts 122 are arranged at intervals along the circumference of the port part 121, so that the multiple mating parts 122 are discretely arranged on the outer periphery of the port part 121. Correspondingly, multiple anti-detachment claws 22 are arranged at intervals along the circumference of the sleeve 21, and the anti-detachment claws 22 are engaged with the mating parts 122 one-to-one.

[0059] For example, in another embodiment, the mating portion 122 is annular around the outer periphery of the port portion 121, and multiple anti-disengagement claws 22 are arranged at intervals along the circumference of the sleeve 21, each anti-disengagement claw 22 engaging with the mating portion 122. The mating portion 122 can have a cross-sectional shape perpendicular to its extension direction that is angular, trapezoidal, or arc-shaped. This, with its guide bevel, facilitates the smooth sliding and insertion of the engaging portion 222 into place during insertion, reducing assembly resistance and providing a clearer "click" feel. Preferably, the mating portion 122 has an arc-shaped cross-section perpendicular to its extension direction, which reduces stress concentration and allows for better mechanical performance when combined with the specifically shaped engaging portion 222. The mating part 122 is a continuous ring extending circumferentially along the port part 121 without any breaks, which allows the adapter 20 to be engaged with the port part 121 at any rotation angle. In the confined space and complex pipeline layout of the automotive power compartment, it allows for greater flexibility in pipeline layout. During assembly, there is no need to painstakingly align the specific snap-fit ​​part 222 position, which greatly improves the convenience and fault tolerance of assembly.

[0060] To further improve the assembly reliability of the port section 121, the adapter 20, and the lead-out part 30, such as Figures 5 to 8 As shown, in one embodiment, the elastic arm 221 extends axially along the sleeve 21. One end of the elastic arm 221 near the first port 211 is connected to the sleeve 21, and the other end of the elastic arm 221 is a free end. The anti-detachment part 223 is provided at the free end of the elastic arm 221. When the sleeve 21 is subjected to external force and tends to move away from the first port 211, the mating part 122 presses the locking part 222 to make the elastic arm 221 expand toward the outside of the sleeve 21, thereby making the anti-detachment part 223 abut against the inner wall surface of the lead-out member 30 to restrict the lead-out member 30 from axially loosening relative to the adapter 20.

[0061] In this embodiment, the anti-detachment claw 22 includes an elastic arm 221, a locking part 222, and an anti-detachment part 223. The elastic arm 221 serves as a carrier for the locking part 222 and the anti-detachment part 223, and can drive the locking part 222 and the anti-detachment part 223 to move, thus having a certain degree of freedom of movement. The elastic arm 221 is a long strip extending along the axial direction of the sleeve 21. The end of the elastic arm 221 near the first port 211 is a fixed end connected to the sleeve 21, and the end of the elastic arm 221 near the second port 212 is a free end. The anti-detachment part 223 is located at the free end of the elastic arm 221, and the locking part 222 is located on the side of the elastic arm 221 near the outer peripheral wall of the port part 121, and the locking part 222 is located on the side of the anti-detachment part 223 near the first port 211. Thus, when the port portion 121, the adapter 20, and the lead-out portion 30 are assembled in place, the snap-fit ​​portion 222 abuts against the end of the mating portion 122 near the first port 211, so that the adapter 20 and the port portion 121 form a snap-fit ​​structure to achieve the first-level anti-detachment. The anti-detachment portion 223 extends at least partially into the lead-out portion 30 to form a tight fit with the inner wall of the lead-out portion 30 to achieve the second-level anti-detachment; thereby ensuring that the assembly between the three is stable and reliable. When the adapter 20 is subjected to an external force and tends to move away from the first port 211 relative to the port portion 121, the mating portion 122 on the outer wall of the port portion 121 applies a compressive force to the locking portion 222, causing the elastic arm 221 to expand away from the outer wall of the port portion 121. Since the anti-detachment portion 223 extends at least partially into the lead-out member 30, it moves closer to the inner wall of the lead-out member 30, further pressing against the inner wall of the lead-out member 30 to form a tight fit. This prevents the lead-out member 30 from loosening relative to the adapter 20 away from the first port 211. In other words, the cooperation of the port portion 121, the adapter 20, and the lead-out member 30 achieves a double interlocking structure, ensuring the reliability of the assembly of the three components and avoiding the risk of fluid leakage due to loosening in a long-term vibration environment. Optionally, in the axial direction of the sleeve 21, the anti-detachment part 223 extends into the lead-out part 30 by a length of not less than 1 mm.

[0062] Furthermore, in one embodiment, the elastic arm 221 has a recess 224 on one side facing the outer peripheral wall of the port portion 121. The recess 224 is located between the snap-fit ​​portion 222 and the anti-detachment portion 223. The recess 224 has a first sidewall 2241 and a second sidewall 2242 opposite to each other along the extending direction of the elastic arm 221. The mating portion 122 is located between the first sidewall 2241 and the second sidewall 2242. The snap-fit ​​portion 222 forms the first sidewall 2241 on the side that abuts against the mating portion 122.

[0063] In this embodiment, the elastic arm 221 is further provided with a recess 224. A locking portion 222, a recess 224, and an anti-detachment portion 223 are arranged sequentially in the direction from the fixed end of the elastic arm 221 to the free end. The recess 224 and the locking portion 222 share a first sidewall 2241. Thus, when the adapter 20 is assembled with the port portion 121, the locking portion 222 is held by the first sidewall 2241 against the mating portion 122 near the first port 211 on the outer periphery of the port portion 121. Simultaneously, the mating portion 122 can be accommodated within the recess 224. This avoids fatigue damage or even breakage of the elastic arm 221 caused by the mating portion 122 pressing against it for extended periods without external force, thus extending the service life of the adapter 20 and further ensuring assembly reliability. Optionally, both the first sidewall 2241 and the second sidewall 2242 are sloped, so that the recess 224 has an flared structure that gradually widens towards the outer peripheral wall of the port portion 121, thereby facilitating the sliding of the mating portion 122 into the recess 224 along the inclined first sidewall 2241. Optionally, the snap-fit ​​portion 222 has an inclined guide surface on the side away from the first sidewall 2241, so that during the assembly of the adapter 20 and the port portion 121, the sliding engagement between the guide surface and the mating portion 122 guides the mating portion 122 into the recess 224.

[0064] To improve the sealing reliability between the port section 121 and the lead-out member 30 and reduce the risk of fluid leakage, such as Figure 4 and Figure 5 As shown, in some embodiments, the heating device 100 further includes a seal 40, which is disposed between the port portion 121 and the lead-out member 30, for sealing the gap between the port portion 121 and the inner wall of the lead-out member 30.

[0065] In this embodiment, a sealing element 40 is provided between the port portion 121 and the lead-out member 30, enabling direct sealing between them. The sealing element 40 is a component used to fill, seal, or prevent leakage of liquids, gases, or solids. The sealing element 40 can be located on the end face and / or outer peripheral wall of the port portion 121. When the lead-out member 30 and the adapter 20 are assembled, the inner wall of the lead-out member 30 can directly contact the sealing element 40. The port portion 121 and the lead-out member 30 jointly compress the sealing element 40, causing it to deform and sealing the gap between the port portion 121 and the inner wall of the lead-out member 30. This prevents fluid in the fluid channel 101 from leaking outwards through the gap between the port portion 121 and the lead-out member 30, reducing the risk of fluid leakage. The sealing element 40 may include, but is not limited to, sealing rings, sealant, or sealing tape. Optionally, the sealing element 40 may be a sealing ring made of rubber or silicone. Additionally, the seal 40 can be disposed between the outer peripheral wall of the port portion 121 and the inner peripheral wall of the lead-out member 30 to achieve radial sealing; and / or, the seal 40 can be disposed between the end face of the port portion 121 and the inner wall of the lead-out member 30 to achieve end face sealing. The number of seals 40 can be set to one or more as needed.

[0066] Further, in one embodiment, the sleeve 21 has a first port 211 and a second port 212 that are axially opposite each other. The port portion 121 has a sleeve section 121a and an extension section 121b arranged axially. The sleeve 21 is fitted onto the outer periphery of the sleeve section 121a from the first port 211, and the extension section 121b extends out of the second port 212 of the sleeve 21. The sealing member 40 is fitted onto the outer periphery of the extension section 121b, and the sealing member 40 is used to seal the extension section 121b. It is worth noting that during actual assembly, the seal 40 can be fitted onto the outer periphery of the extension 121b first, and then inserted into the lead-out part 30 as a whole; or, the seal 40 and the lead-out part 30 can be assembled as a whole first, and then the extension 121b can be inserted into the seal 40 and the lead-out part 30.

[0067] To facilitate the installation and positioning of the seal 40, in one embodiment, the inner wall of the lead-out member 30 is provided with a sealing groove, and the seal 40 is disposed within the sealing groove. The sealing groove may include two side groove walls arranged axially opposite each other along the outer extension 121b, with the seal 40 sandwiched between the two side groove walls, thereby axially limiting the seal 40. To facilitate the installation of the seal 40, the groove wall on the side of the sealing groove closest to the insertion interface 311 of the lead-out member 30 may be omitted, leaving only one groove wall to limit the seal 40 away from the insertion interface 311. The side of the seal 40 closest to the insertion interface 311 may be limited by other components (such as the adapter 20 or the stop 50).

[0068] like Figure 4 As shown, in one embodiment, the inner wall of the lead-out member 30 is provided with a limiting step surface 312 facing the second end 202 of the adapter 20. The limiting step surface 312 is used to limit the side of the seal member 40 away from the second end 202 of the adapter 20. In this way, by providing the limiting step surface 312, the movement of the seal member 40 toward the side away from the second end 202 of the adapter 20 can be restricted.

[0069] In one embodiment, a stop 50 is provided within the lead-out member 30. The stop 50 is sleeved on the outer periphery of the extension section 121b and located between the second end 202 of the adapter 20 and the seal 40. The stop 50 is used to limit the movement of the seal 40 near the second end 202 of the adapter 20. Thus, by providing the stop 50, the movement of the seal 40 near the second end 202 of the adapter 20 can be restricted.

[0070] Optionally, the inner wall of the lead-out member 30 is provided with a limiting step surface 312 facing the second end 202 of the adapter 20. The limiting step surface 312 is used to limit the side of the seal 40 away from the second end 202 of the adapter 20. The lead-out member 30 is provided with a stop member 50, which is sleeved on the outer periphery of the extension 121b and located between the second end 202 of the adapter 20 and the seal 40. The stop member 50 is used to limit the side of the seal 40 close to the second end 202 of the adapter 20. In this way, through the joint cooperation of the limiting step surface 312 and the stop member 50, the axial sides of the seal 40 can be limited to ensure the installation stability of the seal 40.

[0071] In this embodiment, the lead-out member 30 includes a plug-in portion 31 for the port portion 121 to insert into. The plug-in portion 31 has a plug-in interface 311, a first plug-in segment, and a second plug-in segment connected in sequence. The port portion 121 is inserted from the plug-in interface 311 into the first plug-in segment and the second plug-in segment in sequence. The inner diameter of the first plug-in segment is larger than that of the second plug-in segment, forming a limiting step surface 312 between the first and second plug-in segments. The larger inner diameter of the first plug-in segment facilitates the assembly of the seal 40 from the plug-in interface 311 into the first plug-in segment until it abuts against the limiting step surface 312. Then, the stop member 50 is assembled from the plug-in interface 311 into the first plug-in segment until it abuts against the seal 40. This facilitates the installation of the seal 40, and the combined action of the limiting step surface 312 and the stop member 50 limits the axial sides of the seal 40, ensuring the installation stability of the seal 40. In addition, since the inner diameter of the first plug segment is relatively large, an annular space is formed between the inner peripheral wall of the first plug segment and the outer peripheral wall of the port portion 121 to accommodate at least part of the adapter 20.

[0072] Optionally, the end of the extension 121b of the port portion 121 away from the socket portion 121a is narrowed; and / or, the first end 201 of the adapter 20 is flared. In this way, interference can be avoided when the adapter 20 and the port portion 121 are socketed together, thereby improving assembly efficiency.

[0073] like Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, the outer wall of the sleeve 21 is provided with a limiting rib 23, which extends along the axial direction of the sleeve 21; the inner wall of the lead-out member 30 is provided with a limiting groove 313 for the limiting rib 23 to be inserted.

[0074] In this embodiment, the outer wall of the sleeve 21 is provided with a limiting rib 23, and the inner wall of the lead-out member 30 is provided with a limiting groove 313. The limiting rib 23 and the limiting groove 313 extend in the same direction. One end of the limiting groove 313 is connected to the insertion interface 311 of the lead-out member 30, and the end of the limiting groove 313 away from the insertion interface 311 forms a limiting surface. In this way, through the cooperation of the limiting rib 23 and the limiting groove 313, the axial insertion of the sleeve 21 and the lead-out member 30 can be guided. When the adapter 20 and the lead-out member 30 are assembled in place, the limiting surface of the limiting groove 313 can abut against the end of the limiting rib 23 to limit the connection, thereby realizing the rapid positioning and assembly of the adapter 20 and the lead-out member 30. Furthermore, once assembled, the limiting groove 313, along the two side walls of the sleeve 21, can limit the two sides of the limiting rib 23, preventing the lead-out part 30 from rotating circumferentially relative to the adapter 20, thus enhancing the stability of the connection point under vibration. In addition, to install the anti-detachment claw 22, an opening 213 needs to be provided on the sleeve 21, which reduces the overall structural strength of the sleeve 21. By providing the limiting rib 23 on the outer wall of the sleeve 21, it can also act as a reinforcing rib, increasing the overall rigidity and structural strength of the adapter 20. The cross-section of the limiting rib 23 can be circular, rectangular, or trapezoidal. A rectangular or trapezoidal cross-section, in conjunction with the corresponding groove, provides better torsional resistance and guidance. The inlet of the limiting groove 313 is usually designed with a large chamfer or flared opening to facilitate insertion.

[0075] Optionally, the outer peripheral wall of the sleeve 21 is provided with a plurality of limiting ribs 23, which are arranged at intervals along the circumference of the sleeve 21. Correspondingly, the inner peripheral wall of the lead-out member 30 is provided with a plurality of limiting grooves 313, and the limiting ribs 23 and the limiting grooves 313 are inserted and matched one-to-one. In this way, the anti-rotation function between the adapter 20 and the lead-out member 30 can be further enhanced, the structural strength of the adapter 20 can be enhanced, and the coaxiality of the assembly of the sleeve 21 and the lead-out member 30 can also be improved.

[0076] Optionally, the sleeve 21 is provided with multiple limiting ribs 23 and multiple anti-detachment claws 22, and the limiting ribs 23 and anti-detachment claws 22 are arranged alternately along the circumference of the sleeve 21.

[0077] Optionally, the adapter 20 can be constructed as a single-piece molded structure. For example, the adapter 20 can be an injection-molded part, which simplifies the manufacturing process and ensures structural strength. For example, the anti-slip claw 22, the limiting rib 23, the flange 24, and other structures can all be integrally molded onto the sleeve 21.

[0078] To further ensure the assembly reliability of the lead-out component 30 and the adapter component 20, such as Figure 4 , Figures 10 to 11 As shown, in some embodiments, the sleeve 21 is provided with a first bayonet 214, the lead-out member 30 is provided with a second bayonet 314, and the heating device 100 further includes a snap-fit ​​member 60, which snaps into the first bayonet 214 and the second bayonet 314 to lock the sleeve 21 and the lead-out member 30.

[0079] The sleeve 21 is provided with a first bayonet 214. The first bayonet 214 can be a through-hole that penetrates the wall of the sleeve 21, or it can be a blind opening. When the first bayonet 214 is a blind opening, it can be understood as a groove located on the outer wall of the sleeve 21. The insertion portion 31 of the lead-out member 30 is provided with a second bayonet 314. The second bayonet 314 is typically a through-hole that penetrates the wall thickness of the lead-out member 30, and it extends circumferentially along the insertion portion 31. In embodiments where the first bayonet 214 is a blind opening, it can be configured as an annular groove. In this case, the first bayonet 214 and the second bayonet 314 do not need to be radially aligned, reducing the difficulty of docking the insertion portion 31 and the sleeve 21.

[0080] In this embodiment, through the cooperation of the first bayonet 214, the second bayonet 314 and the snap-fit ​​60, the operator only needs to align the snap-fit ​​60 with the first bayonet 214 and the second bayonet 314 to complete the reinforced connection between the adapter 20 and the lead-out part 30 without performing complicated operation steps, and also improves the stable connection between the plug part 31 and the sleeve 21.

[0081] In some embodiments, the sleeve 21 is provided with two opposing first latches 214, which extend circumferentially along the sleeve 21; the insertion portion 31 is provided with two opposing second latches 314, which extend circumferentially along the insertion portion 31; the latching member 60 includes two opposing latching arms 61 and an operating arm 62 connected to one end of the two latching arms 61; the operating arm 62 is located outside the lead-out member 30; each latching arm 61 can be latched into a first latch 214 from a second latch 314. During assembly, by acting on the operating arm 62, the latching arm 61 is pressed or pushed, so that the latching arm 61 is aligned and latched into the second latch 314, and then into the first latch 214. When disassembly is required, the locking connection between the latching arm 61 and the first latch 214 and the second latch 314 can be easily released by reversing the operation. This operation is simple and quick, facilitating maintenance or replacement.

[0082] Optionally, each of the two locking arms 61 has a retaining part 63 at its end away from the operating arm 62. After the two locking arms 61 are respectively engaged with the two second locking slots 314 and the two first locking slots 214, the retaining part 63 is secured to the outer side wall of the lead-out member 30. This enhances the stability of the engagement between the locking member 60 and the lead-out member 30, and further improves the connection reliability of the lead-out member 30 and the sleeve 21 in the connected state.

[0083] Considering that the adapter 20 and the port portion 121 of the device body 10 are plug-in connected, circumferential rotation is prone to occur. To prevent the adapter 20 from rotating circumferentially relative to the port portion 121 under vibration conditions, thus causing seal failure, such as... Figure 8 and Figure 9 As shown, in some embodiments, the adapter 20 further includes a flange 24 disposed on the outer wall of the sleeve 21, and the flange 24 is limitedly connected to the device body 10. The flange 24 of the adapter 20 and the device body 10 are fitted together by means including but not limited to snap-fit ​​connection, fastener connection, welding, bonding, and insertion, as long as it can at least limit the circumferential rotation of the adapter 20 relative to the port 121. Of course, in some embodiments, the limited fit between the flange 24 of the adapter 20 and the device body 10 can also limit the axial movement of the adapter 20 relative to the port 121, to prevent the adapter 20 relative to the port 121 from loosening axially.

[0084] The following example illustrates the limiting fit structure between the adapter 20 and the main body 10 of the device.

[0085] In one embodiment, one of the device body 10 and the flange portion 24 is provided with a limiting pin 113, and the other is provided with a limiting hole 241, wherein the limiting pin 113 and the limiting hole 241 are inserted into each other. Thus, after the adapter 20 is assembled with the main body 10, the sleeve 21 of the adapter 20 is fitted around the port portion 121. Simultaneously, the flange portion 24 of the adapter 20 and the main body 10 can be engaged via a limiting pin 113 and a limiting hole 241, thereby restricting the circumferential rotation of the adapter 20 relative to the port portion 121. Optionally, the limiting pin 113 can be interference-fitted with the limiting hole 241 to prevent it from easily dislodging, further limiting the axial movement of the adapter 20.

[0086] For example, such as Figure 9 As shown, the main body 10 of the device includes a housing 11 and a heater 12 disposed within the housing 11. The housing 11 includes a shell body 111 and a cover plate 112. The port portion 121 of the main body 10 extends out of the cover plate 112, and a limiting pin 113 is provided on the top surface of the cover plate 112. The adapter 20 includes a sleeve 21 and a flange portion 24 disposed on the outer periphery of the first end 201 of the sleeve 21. The flange portion 24 is provided with a limiting hole 241. When the adapter 20 is assembled with the port portion 121, the sleeve 21 is sleeved around the port portion 121, and the first end 201 of the sleeve 21 abuts against the top surface of the cover plate 112. At the same time, the limiting pin 113 is inserted into the limiting hole 241, thereby realizing a reliable connection between the adapter 20 and the port portion 121. The limiting pin 113 can be separately set from the cover plate 112 and then assembled and connected by welding, screws or other methods, or the limiting pin 113 can be integrally formed with the cover plate 112. Of course, in some embodiments, the positions of the limiting pin 113 and the limiting hole 241 can be interchanged. For example, the adapter 20 has the limiting pin 113 and the cover plate 112 has the limiting hole 241.

[0087] In one embodiment, the device body 10 and the flange portion 24 are respectively provided with fixing holes for fasteners to pass through, and the fasteners lock the flange portion 24 to the device body 10. By locking the adapter 20 to the device body 10 with fasteners, not only can the circumferential limitation of the adapter 20 be achieved, but also the axial limitation of the adapter 20 can be achieved, thereby further improving the assembly reliability. Alternatively, the fasteners can also be interference-fitted with the fixing holes to achieve locking.

[0088] In one embodiment, the device body 10 and the flange 24 are secured together by a spring clip 70. Thus, the spring clip 70 can limit the movement of the adapter 20 and the device body 10, while also facilitating the disassembly and assembly of the adapter 20 and the device body 10, improving assembly and disassembly efficiency.

[0089] For example, such as Figure 20As shown, the flange portion 24 of the adapter 20 is provided with a first hook 27, and the outer wall of the housing 11 of the device body 10 is provided with a second hook 114. The first hook 27 and the second hook 114 are arranged opposite to each other. The first hook 27 has a first groove that opens to the side away from the second hook 114, and the second hook 114 has a second groove that opens to the side away from the first hook 27. The elastic spring 70 can be arranged in a ring shape. The elastic spring 70 has a first stop and a second stop opposite to each other, and an elastic part that connects the first stop and the second stop. The first stop is engaged in the first groove, and the second stop is engaged in the second groove. The elastic part provides elastic force, so that the first stop and the second stop tend to move closer to each other, thereby realizing the engagement and limiting of the adapter 20 and the device body 10. When disassembly is required, simply squeeze the elastic part to increase the distance between the first and second stops, thereby disengaging the elastic snap ring 70 from the first hook 27 and the second hook 114 respectively, thus unlocking the lock. The operation is simple and convenient, requiring no additional tools for disassembly and assembly, which can improve disassembly and assembly efficiency.

[0090] like Figures 2 to 4 As shown, in some embodiments, the main body 10 of the device includes a housing 11 and a heater 12. The heater 12 is disposed on the housing 11 and includes a plurality of heating elements 123 and a connecting portion 124. The connecting portion 124 connects the plurality of heating elements 123 to form at least a partial fluid channel 101. The ends of at least two heating elements 123 protrude from the housing 11, and the portions of the heating elements 123 protruding from the housing 11 are configured as port portions 121, each port portion 121 being provided with a connector 20.

[0091] The main body 10 of the device includes a housing 11 and a heater 12 disposed within the housing 11. The heater 12 has a fluid channel 101 for the flow of heat exchange medium. The fluid channel 101 has at least two port portions 121, with a fluid inlet and a fluid outlet formed on one of the port portions 121. After being heated by the heating element 123, the heat exchange medium in the fluid channel 101 can be output to an external pipeline through the fluid outlet on one of the port portions 121. The fluid medium that needs to be heated in the external pipeline can be transported to the fluid channel 101 of the heating device through the fluid inlet on the other port portion 121 for heating, thus forming a thermal circulation system.

[0092] The heater 12 includes a heating element 123 and a connecting portion 124. Both the heating element 123 and the connecting portion 124 are hollow, allowing the heating element 123 to communicate with the connecting portion 124 to form at least a partial fluid channel 101. At least two ends of the heating elements 123 protrude from the housing 11, and the protruding portions of the heating elements 123 are configured as port portions 121. By allowing the port portions 121 to protrude from the housing 11, it is easy to insert and engage the adapter 20 with the port portions 121. The number of adapters 20 is matched with the number of port portions 121. The heating elements 123 and the connecting portion 124 can be configured as tubular, box-shaped, or other shapes. Optionally, the heating element 123 is a heating tube extending along the height direction of the housing 11. The ends of at least two heating tubes extend out of the housing 11 to form port portions 121, and the connecting portion 124 is connected to the ends of the at least two heating tubes away from the port portions 121. When there are multiple adapters 20, each adapter 20 can be set independently of each other, or at least two adapters 20 can be connected to each other.

[0093] like Figures 1 to 8 As shown, in one embodiment, each adapter 20 is independently configured. This ensures that the installation of any one adapter 20 is not restricted by the other, allowing for free adjustment of the rotation angle of any adapter 20. This allows the lead-out portion 32 of the adapter 20 to avoid interference from other structures, facilitating adjustment to a suitable position for insertion into external pipelines, making the installation of the adapter 20 more flexible. Furthermore, the adapter 20 is manufactured independently, resulting in a simpler structure, reducing the difficulty of mold manufacturing and saving costs. It is understood that in this design, after each adapter 20 is assembled with its corresponding port portion 121, a limiting structure is needed to circumferentially limit the adapter 20 and port portion 121 to prevent circumferential rotation of the adapter 20 relative to the port portion 121. For example, a flange portion 24 can be provided on the outer wall of the sleeve 21 of each adapter 20, and the flange portion 24 can be used to limit the connection with the housing 11 of the device body 10. For example, the flange portion 24 is provided with a limiting hole 241, and the housing 11 is provided with a limiting pin 113 that engages with the limiting hole 241. Alternatively, each adapter 20 may have a splicing portion 26 on its circumference. When each adapter 20 is assembled with its corresponding port portion 121, the splicing portions 26 of two adjacent adapters 20 can be spliced ​​together to form a limiting structure, thereby restraining each other and preventing circumferential rotation.

[0094] like Figures 13 to 18As shown, in one embodiment, at least two adapter pieces 20 are interconnected. By connecting at least two adapter pieces 20 as a single unit, during assembly, at least two adapter pieces 20 can be fitted onto their respective port portions 121 in a single pressing action, thereby improving assembly efficiency. Furthermore, after assembly, the at least two interconnected adapter pieces 20 constrain each other, thus limiting the circumferential rotation of the adapter pieces 20 relative to the port portion 121 without the need for additional limiting structures. The at least two adapter pieces 20 are connected by methods including, but not limited to, integral molding, bonding, snap-fitting, and fastener connection.

[0095] like Figure 19 As shown, in one embodiment, at least two adapters 20 include a first adapter 20a and a second adapter 20b that are separately configured. Both the first adapter 20a and the second adapter 20b have a splicing portion 26. The splicing portion 26 of the first adapter 20a is spliced ​​with the splicing portion 26 of the second adapter 20b so that the first adapter 20a and the second adapter 20b are combined to form an adapter module 20'.

[0096] In this embodiment, the first adapter 20a and the second adapter 20b can be manufactured independently, reducing mold manufacturing difficulty and production costs. Furthermore, after the first adapter 20a and the second adapter 20b are respectively assembled with their corresponding port portions 121, the splicing portions 26 of the first adapter 20a and the second adapter 20b interlock to form a limiting structure. This allows the first adapter 20a and the second adapter 20b to combine to form an adapter module 20'. The first adapter 20a and the second adapter 20b constrain each other, preventing circumferential rotation. For example, the splicing portion 26 of one of the first adapter 20a and the second adapter 20b can be a groove, and the splicing portion 26 of the other can be a protrusion. The protrusion and the groove interlock, simplifying the structure of the adapter 20 and enabling rapid splicing and positioning of the first adapter 20a and the second adapter 20b.

[0097] like Figure 17As shown, in another embodiment, at least two adapters 20 are connected via a base 25 to form an adapter module 20', which is constructed as a single-piece structure. That is, at least two adapters 20 are integrated onto the base 25 to form an adapter module 20'. When connection to at least two port portions 121 is required, the adapter module 20' can be directly plugged into each port portion 121 in a single insertion action, improving assembly efficiency. Furthermore, the connection of each adapter 20 via the base 25 forms a constraint, preventing circumferential rotation of each adapter 20 relative to the port portion 121. The single-piece structure of the adapter module 20' results in higher overall structural strength, reduces the number of parts, decreases assembly steps, and lowers costs. Optionally, the adapter module 20' is integrally injection molded.

[0098] like Figure 4 As shown, in one embodiment, the housing 11 includes a housing body 111 and a cover plate 112. The housing body 111 and the cover plate 112 surround a receiving cavity for accommodating the heater 12. The cover plate 112 is provided with a through opening communicating with the receiving cavity. The port portion 121 passes through the through opening and protrudes from the cover plate 112. The adapter 20 is limited and engaged with the housing 11.

[0099] In this embodiment, the shell body 111 has a shell port, and a cover plate 112 is provided on the shell port of the shell body 111. The shell body 111 and the cover plate 112 form a receiving cavity, allowing the main structure of the heater 12 to be housed within the receiving cavity. The shell 11 provides protection for the main structure of the heater 12. Additionally, the port portion 121 of the heater 12 can extend through a through-hole on the cover plate 112, protruding from the cover plate 112 to facilitate the insertion and engagement of the adapter 20 with the port portion 121. The cover plate 112 provides support for the heater 12 and also limits and supports the adapter 20. The limiting engagement between the adapter 20 and the shell 11 restricts the circumferential rotation of the adapter 20 relative to the port portion 121. For example, the adapter 20 can be limited by engaging with the shell body 111 using an elastic retaining spring 70. For example, the adapter 20 can be inserted into the cover plate 112 via the limit pin 113 for positioning.

[0100] In one embodiment, each heating element 123 includes a tube body and a heating section. The tube body has a heating flow channel, which is a portion of the fluid channel 101. The cross-section of the tube body along the extension direction perpendicular to the heating flow channel is a continuous and complete annular surface. The outer peripheral wall of each tube body is provided with a heating section, which extends circumferentially along the tube body.

[0101] In this embodiment, the cross-section of the tube body is a continuous and complete annular cross-section in a section perpendicular to the extension direction of the heating channel, so that the tube body can have a complete annular wall in the circumferential direction. The annular surface of the tube body can be a circular annulus, an elliptical annulus, a polygonal annulus, or an irregular annular closed cross-section. The heating element can be a thick film, or it can be an electromagnetic induction coil; this application does not limit the type of heating element.

[0102] To increase the heating area of ​​the heating element, reduce the volume of the heating tube, and improve the convenience of arranging the heating element, in one embodiment, the heating element can be made of a thick film. In this case, the tube body can be made of metal, and a thick film is printed on the tube body when the heating element uses a thick film heating method. This also facilitates efficient heat transfer through the tube body for the heating element located on the outside of the tube body, improving the heating efficiency of the heat exchange medium located in the heating channel. Furthermore, the heating element is located on the outer peripheral wall of the tube body and extends circumferentially along the tube body. That is, the heating element can completely surround the outer periphery of the tube body, or it can surround a portion of the outer periphery of the tube body, for example, the heating element continuously surrounds the outer peripheral wall of the tube body; or, the heating element consists of multiple small heating elements spaced apart along the outer periphery of the tube body.

[0103] The cross-section of the tube body along the extension direction perpendicular to the heating channel is a continuous and complete annular surface. That is, the cross-section of the tube body is a continuous and complete annular surface. The continuous annular surface is uninterrupted, crack-free, and spliced ​​in the circumferential direction. The complete annular surface is closed as a whole and without any gaps. This gives the tube body a complete annular wall in its circumferential direction, resulting in good sealing performance. In other words, the heating tube has good sealing performance, and the heat exchange medium is not easy to leak when flowing through the heating channel, thereby improving the sealing effect and reliability of the heating tube. The cross-section of the tube is a continuous and complete annular surface, which makes the heating channel circumferentially sealed. The heating element can be set continuously or intermittently in the circumference of the tube. It can heat the heat exchange medium in the heating channel at least two different positions in the circumference of the tube in different directions. On the one hand, the heat exchange medium can be heated in all parts of the circumference of the tube. Compared with the single-piece heating of the plate heating element, the heating element occupies less space, thereby reducing the volume of the heater 12. On the other hand, during vehicle operation, the circumferentially sealed state of the tube means that even in the long-term vibration environment, the heat exchange medium can still flow stably in the heating channel, thereby reducing the probability of heat exchange medium leakage and ensuring the stability of the heater 12.

[0104] like Figure 1 and Figure 13 As shown, this application also proposes a compressor integrated device 1000, including a compressor 200, a heating device 100, and a controller. The heating device is disposed on the compressor 200; the controller is electrically connected to both the compressor 200 and the heating device 100.

[0105] The specific structure of the heating device 100 is as described in the above embodiments. Since the compressor integrated device 1000 uses all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0106] The compressor integrated device 1000 proposed in this application can be used in vehicles as described below, or it can be used in equipment such as air conditioners. This application does not limit the type of equipment to which the compressor integrated device 1000 is applied.

[0107] The compressor 200 is a power device that uses mechanical energy to do work on gas, converting the low-pressure gas it draws in into high-pressure gas. The compressor 200 proposed in this application can be a scroll compressor 200, a piston compressor 200, or a screw compressor 200, etc., and is not limited here.

[0108] The heating device 100 can be used to heat liquids entering the heating channel for delivery to areas requiring heating. For example, in a vehicle battery, the rate of internal chemical reactions slows down at low temperatures, leading to reduced charging and discharging efficiency and decreased battery performance. Therefore, a circulation pipeline connected to the heating channel can be provided so that water, oil, or other heat exchange media, after entering the heating channel, can be heated by the heating device 100 to the required temperature before being delivered to the battery via the circulation pipeline, thereby heating the battery. Of course, heating the battery is only an exemplary explanation; the heat exchange media heated by the heating device 100 in this solution can also be delivered to other locations in the vehicle, such as the engine and seats.

[0109] The controller is used to control the operation of the compressor 200 and the heating device 100, such as controlling the start and stop of the motor in the compressor 200 and adjusting the motor speed, and controlling the start and stop of the heating device 100 and adjusting the heating power. The controller may include a circuit board and control chips mounted on that circuit board. The compressor 200 and the heating device 100 can be controlled by the same control chip. Alternatively, different control chips can be used to control the compressor 200 and the heating device 100 separately. In this case, the two control chips can be mounted on the same circuit board or distributed on different circuit boards.

[0110] In this embodiment, the compressor integration device 1000 integrates the heating device 100, the compressor 200, and the controller into one unit, resulting in higher overall integration, a more compact structure, and a smaller footprint. Integration shortens the wiring path for electrical connections between the heating device 100 and the controller. Quick-connect couplings facilitate easy connection of the heating device 100 to external pipelines, forming a closed circulation channel. The heating element 123 of the heating device 100 has a continuous and complete annular cross-section along the direction perpendicular to the extension of the heating channel. This continuous annular surface is uninterrupted, crack-free, and seamless in the circumferential direction, and the complete annular surface is completely closed and without gaps. This gives the tube a complete annular wall in its circumferential direction, resulting in good sealing performance. The heat exchange medium is less prone to leakage when flowing through the heating channel, thus improving the sealing effect and reliability of the heating tube.

[0111] Existing heating devices typically use at least two components joined together to form a heating channel. This method is susceptible to cracks in the heating channel due to vehicle vibration and collisions, which can lead to leakage of the heat exchange medium. In contrast, the heating element 123 of the heating device 100 in this application forms the heating channel itself, eliminating the need for multiple components to be joined together. This makes the heating device 100 less prone to leakage and improves vehicle safety when applied to vehicles.

[0112] This application also proposes a thermal management system, which includes a heating device 100. The specific structure of the heating device 100 can be referred to the above embodiments. Since this thermal management system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The heating device 100 can be set independently of the compressor 200 in the thermal management system, or it can be integrated with the compressor 200 to form a compressor integrated device 1000.

[0113] This application also proposes a thermal management system, which includes a compressor integrated device 1000. The specific structure of the compressor integrated device 1000 can be referred to the above embodiments. Since this thermal management system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0114] This application also proposes a vehicle that includes a thermal management system. The specific structure of the thermal management system can be referred to the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0115] The above description is merely an exemplary embodiment of this application and does not limit the scope of protection of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
