Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a heating device, a compressor integrated device, a thermal management system, and a vehicle. Background Technology

[0002] The thermal management system of new energy vehicles has a demand for miniaturization, making the integration of heater functionality into the electric compressor an industry trend. To improve assembly efficiency, it is desirable for the heater and the piping in the thermal management system to be connected via quick-connect fittings; for example, the heater's interface end is a male plug, and the thermal management system's piping is a female plug. However, the heater's interface end (e.g., the end of the heating element) is typically produced using an extrusion molding process, resulting in a cylindrical shape with thick walls. This makes it difficult to form the bayonet structure required for quick-connect fittings. Therefore, quick-connect functionality between the heater and the thermal management system's piping is challenging, impacting connection efficiency. Utility Model Content

[0028] The thermal management system of new energy vehicles has a growing demand for miniaturization, making the integration of heater functionality into the electric compressor an industry trend. To improve assembly efficiency, it is desirable for the heater and the piping in the thermal management system to be connected via quick-connect fittings; for example, the heater's interface end is a male plug, and the thermal management system's piping is a female plug. However, the heater's interface end (e.g., the end of the heating element) is typically produced using an extrusion molding process, resulting in a cylindrical shape with thick walls, making it difficult to form the bayonet structure required for a quick-connect fitting. Therefore, designing a quick-connect structure between the heater and the thermal management system's piping presents a challenge.

[0029] This utility model proposes a heating device 100 that enables quick-connection between the heater 20 and the pipeline of the heat pipe system.

[0030] Please see Figures 1 to 4 In one embodiment of this utility model, the heating device 100 includes a housing 10, a heater 20, and an adapter 30. The housing 10 has a receiving cavity 101 and a shell port 102 communicating with the receiving cavity 101; the heater 20 is disposed in the receiving cavity 101, and the heater 20 has a liquid flow channel 201 and an interface end 20a communicating with the liquid flow channel 201, the interface end 20a being disposed facing or extending out of the shell port 102; the adapter 30 includes a plug-in portion 31 and a lead-out portion 32 connected to each other, the plug-in portion 31 being plugged into the interface end 20a, and the lead-out portion 32 having a connection portion 33 suitable for plugging into an external pipeline at one end away from the plug-in portion 31, and the adapter 30 having a liquid flow channel 301 for communicating the liquid flow channel 201 with an external pipeline.

[0031] The housing 10 is configured to form a receiving cavity 101 for accommodating the heater 20. One end of the housing 10 is open to form a shell port 102 communicating with the receiving cavity 101. For example, when the housing 10 is in an upright state, the shell port 102 can be located at the top of the housing 10. Of course, the shell port 102 can also be located on the side of the housing 10. When the heating device 100 is applied to the compressor integrated device 1000, the heating device 100 is integrated with the compressor 200. In this case, the housing 10 of the heater 20 can also be formed together with the outer shell of the compressor 200 to enclose the receiving cavity 101. Optionally, the housing 10 is made of a metal material, such as aluminum alloy, to ensure structural strength.

[0032] The heater 20 is disposed within the receiving cavity 101 of the housing 10, and the housing 10 provides protection for the heater 20. The heater 20 may include, but is not limited to, a tubular heater, a plate heater, or other types of heaters, as long as a liquid channel for liquid flow can be constructed within the heater 20, and the heater 20 heats the liquid within the liquid channel. The shape of the liquid flow channel 201 within the heater 20 may include, but is not limited to, a straight flow channel, a curved flow channel, or other irregular flow channels. For example, the heater 20 may include two heating tubes 21 extending in parallel, and a flow passage 22 connecting the two heating tubes 21, giving the heater 20 an overall U-shaped structure, and correspondingly, the liquid flow channel 201 also exhibits a U-shaped flow channel. The heater 20 has an interface end 20a communicating with the liquid flow channel 201 for connection to the adapter 30. For example, the end of the heating tube 21 can serve as the interface end 20a of the heater 20. The heater 20 generally has an inlet and an outlet, and the parts of the heater 20 with the inlet and outlet can be respectively used as an interface end 20a.

[0033] To facilitate connection of the heater 20 to external piping, the heating device 100 also includes an adapter 30 for connecting the heater 20 to external piping (e.g., piping of a thermal management system). The interface end 20a of the heater 20 faces or extends beyond the housing port 102 to facilitate connection between the interface end 20a and the adapter 30. For example, the interface end 20a of the heater 20 may be slightly below or flush with the housing port 102, allowing part of the adapter 30 to extend into the housing 10 for connection with the interface end 20a of the heater 20. Alternatively, the interface end 20a of the heater 20 may be above the housing port 102, in which case it extends beyond the housing 10, allowing for easier connection with the adapter 30.

[0034] To facilitate connection between the adapter 30 and the interface end 20a of the heater 20, the adapter 30 has a plug-in portion 31, which plugs into the interface end 20a of the heater 20. The plug-in portion 31 can serve as a female end for the interface end 20a of the heater 20 to plug into, or it can serve as a male end for insertion into the interface end 20a of the heater 20, as long as the liquid flow channel 201 of the heater 20 and the liquid flow channel 301 of the adapter 30 are connected while ensuring reliable sealing. To facilitate connection with external pipelines, the adapter 30 also has a lead-out portion 32, which extends the liquid flow path so that the end of the lead-out portion 32 furthest from the plug-in portion 31 is as far away from the housing 10 and the heater 20 as possible. This avoids interference between the housing 10 and the heater 20 and the installation of the external pipeline when the end of the lead-out portion 32 furthest from the plug-in portion 31 is connected, reducing the difficulty of installing the external pipeline. The end of the outlet 32 ​​away from the insertion part 31 is provided with a connecting part 33 suitable for insertion into an external pipeline. Thus, by inserting the external pipeline into the connecting part 33 of the outlet 32, a quick connection can be achieved between the heater 20, the adapter 30, and the external pipeline, allowing the liquid flow channel 201 of the heater 20 to communicate with the external pipeline via the liquid flow channel 301 of the adapter 30. The connecting part 33 can be designed according to different pipeline structures. The assembly of the external pipeline and the connecting part 33 of the outlet 32 ​​can be an outer sleeve structure or an inner insertion structure. For example, the connecting part 33 can be a upset head structure protruding from the outer circumference of the outlet 32. Another example is that the connecting part 33 is configured as a male connector for insertion into the female connector of the external pipeline. Yet another example is that the connecting part 33 is configured as a female connector for fitting over the male connector of the external pipeline.

[0035] The heating device 100 of this utility model includes a housing 10, a heater 20, and an adapter 30. The heater 20 is placed inside the receiving cavity 101 of the housing 10, with the interface end 20a of the heater 20 facing or extending out of the shell port 102 of the housing 10. This facilitates the insertion of the connector 30's plug-in portion 31 into the interface end 20a of the heater 20. The lead-out portion 32 of the adapter 30 extends the liquid flow path, so that the end of the lead-out portion 32 away from the plug-in portion 31 is as far away from the housing 10 and the heater 20 as possible. Thus, when the end of the lead-out portion 32 away from the plug-in portion 31 is connected to an external pipeline, interference between the housing 10 and the heater 20 and the installation of the external pipeline can be avoided, reducing the difficulty of installing the external pipeline. Furthermore, the end of the lead-out portion 32 away from the insertion portion 31 is provided with a connecting portion 33 suitable for insertion into an external pipeline. Thus, by inserting the external pipeline into the connecting portion 33 of the lead-out portion 32, a quick connection can be achieved between the heater 20, the adapter 30, and the external pipeline, allowing the liquid flow channel 201 of the heater 20 to communicate with the external pipeline via the liquid flow channel 301 of the adapter 30. This enables a quick-connect function between the heating device 100 and external pipelines (such as pipelines in a thermal management system), improving pipeline connection efficiency.

[0036] like Figure 9 and Figure 10 As shown, in one embodiment, the outlet portion 32 includes a first pipe segment 321 and a second pipe segment 322 that are interconnected. The first pipe segment 321 and the second pipe segment 322 are arranged at an angle. A plug-in portion 31 is provided at the end of the first pipe segment 321 away from the second pipe segment 322, and a connecting portion 33 is provided at the end of the second pipe segment 322 away from the first pipe segment 321. In this embodiment, the first pipe segment 321 and the second pipe segment 322 are arranged at an angle and are interconnected. This ensures that the liquid flow channel 301 has sufficient length, while also preventing the overall height of the adapter 30 from being too high in the axial direction of the first pipe segment 321. Furthermore, the second pipe segment 322 is bent relative to the first pipe segment 321, which can change the flow direction of the liquid flow channel 201, thereby facilitating the connection of the adapter 30 to an external pipeline located on the radial side of the first pipe segment 321 and improving adaptability.

[0037] Optionally, the central axis of the first pipe segment 321 and the central axis of the second pipe segment 322 form an angle θ, which is a right angle or an obtuse angle. That is, 90° ≤ θ < 180°. For example, the angle θ can be 90°, 100°, 120°, 135°, 165°, 175°, or any value within the above range.

[0038] like Figure 10As shown, in one embodiment, the outlet portion 32 further includes a transition pipe section 323 disposed between the first pipe section 321 and the second pipe section 322. Both the first pipe section 321 and the second pipe section 322 are straight pipes, while the transition pipe section 323 is a bent pipe. In this embodiment, both the first pipe section 321 and the second pipe section 322 are straight pipes, which can reduce fluid resistance. Furthermore, the smooth transition between the first pipe section 321 and the second pipe section 322 via the bent transition pipe section 323 avoids the direct connection of the first pipe section 321 and the second pipe section 322 to form a right-angle bend, further reducing fluid resistance.

[0039] The first pipe segment 321 can be assembled and connected to the transition pipe segment 323 or integrally formed; and / or, the second pipe segment 322 can be assembled and connected to the transition pipe segment 323 or integrally formed. Optionally, the first pipe segment 321, the transition segment, and the second pipe segment 322 can be integrally formed, for example, they can be integrally injection molded, which can simplify the manufacturing process, ensure structural strength, and avoid the risk of water leakage at the connection between adjacent pipe segments.

[0040] In one embodiment, the adapter 30 further includes a limiting flange 34 protruding from the outer peripheral surface of the second pipe section 322. Thus, when the external pipe is inserted into the second pipe section 322, the limiting flange 34 can abut against and limit the end face of the external pipe.

[0041] Optionally, the adapter 30 is a one-piece molded structure. For example, the plug portion 31, lead-out portion 32, connecting portion 33, limiting flange 34, and fixing portion 35 of the adapter 30 are integrally injection molded. This simplifies the manufacturing process, ensures structural strength, and reduces the risk of leakage.

[0042] There are various structures for the connector 33, which can be designed according to different pipeline structures. The assembly of the external pipeline and the connector 33 can be a jacket structure or an internal insertion structure.

[0043] For example, the connecting part 33 is configured as a upset head structure protruding from the outer peripheral surface of the second pipe section 322. When the external pipe is a rubber hose, the upset head structure can be inserted into the external pipe and can be interference-fitted with the inner wall of the external pipe. Then, the external pipe and the connecting part 33 can be locked together using a clamp.

[0044] For example, the connector 33 is configured as a male connector for insertion into a female connector of an external pipeline. When the external pipeline has a female connector, the connector 33 can be inserted into the female connector of the external pipeline for quick assembly. To improve versatility, the connector 33 may optionally be configured as a VDA (Verbander Automobile Industry) male connector for insertion into a VDA female connector of an external pipeline. Alternatively, the connector 33 may be configured as an SAE (Society of Automotive Engineers) male connector for insertion into an SAE female connector of an external pipeline.

[0045] For example, the connecting part 33 is configured as a female connector for fitting over the male connector of an external pipeline. For example, when the external pipeline has a male connector, the connecting part 33 can be fitted over the male connector of the external pipeline to achieve quick assembly. To improve versatility, the connecting part 33 may optionally be configured as a VDA (Verbandder Automobileindustrie) female connector for plugging into the VDA male connector of the external pipeline.

[0046] To ensure sealing reliability, such as Figure 2 and Figure 10 As shown, in one embodiment, the plug-in portion 31 is provided with a plug-in hole 311 communicating with the liquid flow channel 301. The interface end 20a of the heater 20 is inserted into the plug-in hole 311. A sealing member 40 is provided between the interface end 20a of the heater 20 and the plug-in portion 31. The sealing member 40 is used to seal the interface end 20a and the plug-in portion 31.

[0047] In this embodiment, the plug-in portion 31 and the interface end 20a are sealed together by the sealing element 40, which ensures sealing performance and prevents liquid in the heater 20 from leaking from the gap between the interface end 20a and the plug-in portion 31. The sealing element 40 includes, but is not limited to, sealant, sealing ring, or sealing tape.

[0048] The seal 40 can be used to achieve a radial seal or an end face seal between the port portion 20a and the quick-connect fitting 30. Furthermore, the number of seals 40 can be set to one or more as needed.

[0049] In one embodiment, the sealing member 40 is disposed between the outer peripheral wall of the interface end 20a and the inner peripheral wall of the insertion part 31; and / or, the inner peripheral wall of the insertion part 31 is provided with a stepped surface 31a opposite to the end face of the interface end 20a, and the sealing member 40 is disposed between the end face of the interface end 20a and the stepped surface 31a.

[0050] For example, such as Figure 2As shown, the sealing element 40 is disposed between the outer peripheral wall of the interface end 20a and the inner peripheral wall of the insertion part 31. Thus, the outer peripheral wall of the interface end 20a and the inner peripheral wall of the insertion part 31 jointly compress the sealing element 40, causing it to deform and thereby sealingly connecting the outer peripheral wall of the interface end 20a and the inner peripheral wall of the insertion part 31, achieving a radial seal between them. Optionally, the sealing element 40 is an O-ring.

[0051] The sealing element 40 can be pre-assembled into the insertion hole 311, or it can be pre-fitted onto the outer periphery of the interface end 20a of the heater 20. Optionally, the inner peripheral wall of the insertion hole 311 is provided with a sealing groove 312, and the sealing element 40 is disposed in the sealing groove 312. In addition, the number of sealing elements 40 can be set to one or more as needed. For example, multiple sealing rings can be arranged at intervals along the axial direction of the insertion hole 311 to achieve a multiple sealing effect.

[0052] For example, such as Figure 11 As shown, the inner wall of the insertion part 31 has a stepped surface 31a opposite to the end face of the interface end 20a, and the sealing member 40 is disposed between the end face of the interface end 20a and the stepped surface 31a. Thus, the end face of the interface end 20a and the stepped surface 31a of the insertion part 31 jointly compress the sealing member 40, causing the sealing member 40 to deform, thereby sealingly connecting the end face of the interface end 20a and the stepped surface 31a of the insertion part 31, achieving end face sealing between the two. Optionally, the sealing member 40 is a rectangular sealing ring.

[0053] Of course, sealing elements 40 can also be provided on the outer periphery of the interface end 20a and the end face of the interface end 20a respectively, so as to achieve both radial sealing and end face sealing with the insertion part 31, so as to play a double sealing role.

[0054] like Figure 9 As shown, in one embodiment, the adapter 30 further includes a fixing part 35 disposed around the insertion part 31, and the fixing part 35 is connected and fixed to the housing 10. Thus, the adapter 30 is connected and fixed to the housing 10 through the fixing part 35, preventing the adapter 30 from rotating circumferentially, thereby preventing the adapter 30 from becoming detached from the interface end 20a of the heater 20, ensuring assembly reliability and reducing the risk of leakage. The connection method between the fixing part 35 and the housing 10 includes, but is not limited to, welding, fastener 50 connection, snap-fit, or other connection methods.

[0055] like Figure 2 and 10As shown, in one embodiment, the fixing part 35 and the housing 10 are respectively provided with mounting holes 351. The heating device 100 also includes fasteners 50 that pass through the mounting holes 351, and the fasteners 50 lock the fixing part 35 and the housing 10 in place. The adapter 30 and the housing 10 are connected by the fasteners 50, and the connection structure is simple and reliable. The fasteners 50 include, but are not limited to, screws, bolts, etc.

[0056] For example, such as Figure 4 As shown, the housing 10 includes a housing body 11 and a lug 13 disposed on the outer periphery of the housing body 11. The lug 13 is disposed near the housing port 102 and has a mounting hole 351. When the adapter 30 is inserted into the interface end 20a of the heater 20, the adapter 30 can be rotated at a certain angle so that the fixing part 35 of the adapter 30 is opposite to the lug 13 of the housing 10, thereby aligning the mounting hole 351 on the fixing part 35 with the mounting hole 351 on the lug 13. Then, the fastener 50 is passed through the mounting hole 351 and locked in place.

[0057] Optionally, the width of the fixing part 35 narrows towards the side away from the insertion part 31, and the mounting hole 351 is provided at the narrow end of the fixing part 35. In this way, the volume of the fixing part 35 can be minimized, making the connector suitable for installation in confined spaces.

[0058] like Figure 2 and Figure 5 As shown, in one embodiment, the heater 20 includes at least two heating tubes 21 arranged side by side, and a flow passage 22 connecting the at least two heating tubes 21. The heating tubes 21 and the flow passage 22 are connected to form a liquid flow channel 201. The ends of the at least two heating tubes 21 facing away from the flow passage 22 form the interface end 20a of the heater 20. At least two adapters 30 are provided, and the adapters 30 are plugged into the interface end 20a of the heater 20 one-to-one.

[0059] In this embodiment, the number of adapters 30 is the same as the number of interface ends 20a of the heater 20. For example, the heater 20 typically has two interface ends 20a, an inlet and an outlet, and correspondingly, the number of adapters 30 is also two. The number of heating tubes 21 can be set to two, three, or more as needed. For example, when there are two heating tubes 21, the two heating tubes 21 are arranged side by side and spaced apart along the height direction of the housing 10, and the ends of the two heating tubes 21 away from the housing port 102 are connected through the flow passage 22, so that the heater 20 is U-shaped, and the ends of the two heating tubes 21 away from the flow passage 22 respectively form the interface ends 20a of the heater 20. Of course, the number of heating tubes 21 can also be three or more, and among the three or more heating tubes 21, at least two heating tubes 21 can have their tube ends used as the interface ends 20a of the heater 20. Each adapter 30 is independent of the others, so that the installation of any one adapter 30 is not restricted by the other adapter 30. This allows for free adjustment of the orientation of the lead-out portion 32 of any one adapter 30, thereby better avoiding interference from other structures and facilitating adjustment to a suitable position for connection with external pipelines, making the installation of the adapter 30 more flexible.

[0060] like Figures 1 to 4 As shown, in one embodiment, the housing 10 includes a housing body 11 and an assembly plate 12 disposed on the housing body 11. The housing body 11 is provided with a receiving cavity 101 and a housing port 102. The housing port 102 is located at one end of the housing body 11 along a first direction. The assembly plate 12 is provided to protrude from the housing port 102 along the first direction. The lead-out portions 32 of at least two adapters 30 are arranged side by side at intervals along a second direction. Each lead-out portion 32 includes a first pipe section 321 and a second pipe section 322 that are interconnected. The second pipe section 322 is located at the end of the first pipe section 321 away from the heating tube 21. The first pipe section 321 extends along the first direction, and the second pipe section 322 extends along a third direction. The first pipe section 321 and the second pipe section 322 are bent and connected to form a cavity for the assembly plate 12 to be received. The first direction, the second direction and the third direction intersect each other.

[0061] In this embodiment, the first direction can be the height direction of the housing 10 (e.g., vertical direction), the second direction can be the width direction of the housing 10 (e.g., horizontal direction), and the third direction can be the thickness direction of the housing 10 (e.g., front-back direction). The mounting plate 12 facilitates the integration of the heating device 100 with other components. For example, in a thermal management system, the heating device 100 can be integrated with the compressor 200, and the mounting plate 12 can be used to fix it to the housing 10 of the compressor 200. The adapter 30 includes a first pipe section 321 and a second pipe section 322, whose extension directions are not the same. For example, the first pipe section 321 can extend coaxially with the heating pipe 21, and the second pipe section 322 can extend radially along the heating pipe 21. This makes the adapter 30 have an L-shaped structure, which helps to reduce the height of the adapter 30 in the extension direction of the heating pipe 21. Furthermore, the mounting plate 12 can be accommodated in the cavity constructed by the adapter 30, resulting in a more compact overall structure and contributing to the miniaturization of the heating device 100.

[0062] like Figure 7 As shown, in one embodiment, the heating tube 21 includes a tube body 211 and a heating section 212. The tube body 211 has a heating channel inside, and a single heating channel constitutes part of the liquid channel 201. The cross section of the tube body 211 along the extension direction perpendicular to the heating channel is a continuous and complete annular surface. The outer peripheral wall of each tube body 211 is provided with a heating section 212, and the heating section 212 extends circumferentially along the tube body 211.

[0063] The liquid flow channel 201 has an inlet and an outlet, with one adapter 30 connected to the inlet and the other adapter 30 connected to the outlet. The inlet of the heater 20 is for the heat exchange medium to flow into the heater 20, and the outlet is for the heat exchange medium to flow out of the heater 20. At least two heating tubes 21 can be arranged in series, in parallel, or a combination of partially series and partially parallel. In a cross-section perpendicular to the extension direction of the heating flow channel, the tube body 211 can be a continuous and complete annular cross-section, so that the tube body 211 can have a complete annular wall in the circumferential direction. The annular surface of the tube body 211 can be a circular annular, elliptical annular, polygonal annular, or irregular annular closed cross-section. The heating element 212 can be a thick film, or it can be an electromagnetic induction coil; this application does not limit the type of heating element 212.

[0064] To increase the heating area of ​​the heating section 212, reduce the volume of the heating tube 21, and improve the ease of arranging the heating section 212, in one embodiment, the heating section 212 can be made of a thick film. In this case, the tube body 211 can be made of metal. When the heating section 212 uses a thick film heating method, a thick film is printed on the tube body 211. Simultaneously, this facilitates efficient heat transfer through the tube body 211 for the heating section 212 located outside the tube body 211, improving the heating efficiency of the heat exchange medium located in the heating channel. Furthermore, the heating section 212 is disposed on the outer peripheral wall of the tube body 211 and extends circumferentially along the tube body 211. That is, the heating section 212 can completely surround the outer periphery of the tube body 211, or it can surround a portion of the outer periphery of the tube body 211. For example, the heating section 212 can continuously surround the outer peripheral wall of the tube body 211; or, the heating section 212 can be composed of multiple small heating elements, which are spaced apart along the outer periphery of the tube body 211.

[0065] The cross-section of the tube body 211 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 211 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 211 a complete annular wall in its circumferential direction and good sealing performance. In other words, the heating tube 21 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 21. The cross-section of the tube 211 is a continuous and complete annular surface, which makes the heating channel circumferentially sealed. The heating part 212 can be continuously or intermittently arranged around the tube 211. It can heat the heat exchange medium in the heating channel at least two different positions around the tube 211 in different directions. On the one hand, the heat exchange medium can be heated at all points around the tube 211. Compared with the single-piece heating of the plate heating element, the heating part 212 occupies less space, thereby reducing the volume of the heater 20. On the other hand, during vehicle operation, the circumferentially sealed state of the tube 211 allows the heat exchange medium to flow stably in the heating channel even in a long-term vibration environment, thereby reducing the probability of heat exchange medium leakage and ensuring the stability of the heater 20.

[0066] In one embodiment, at least two heating tubes 21 include a first heating tube 21a and a second heating tube 21b. The first heating tube 21a and the second heating tube 21b are arranged side by side and spaced apart. The first heating tube 21a, the flow passage 22 and the second heating tube 21b are connected in sequence. The flow passage 22 is located inside the housing 10 on the side away from the housing port 102. The ends of the first heating tube 21a and the second heating tube 21b away from the flow passage 22 respectively form the interface end 20a of the heater 20.

[0067] There are various ways to connect the first heating tube 21a, the flow passage 22, and the second heating tube 21b.

[0068] For example, in one embodiment, the first heating tube 21a, the flow passage 22, and the second heating tube 21b are integrally formed. This improves the structural strength and sealing performance of the heater 20, reduces assembly processes, and increases material utilization and production efficiency. The first heating tube 21a, the flow passage 22, and the second heating tube 21b can be integrally formed by casting, injection molding, or stamping.

[0069] For example, in one embodiment, the first heating tube 21a is integrally formed with the flow passage 22; or, the flow passage 22 is integrally formed with the second heating tube 21b.

[0070] For example, in one embodiment, the flow passage 22 is assembled and connected to the first heating tube 21a and the second heating tube 21b, respectively.

[0071] like Figure 6 As shown, in one embodiment, the flow passage 22 includes a connecting plate 221 and a connecting seat 222. The connecting plate 221 has two through holes 2211 arranged in a first direction and a first side and a second side opposite to each other. The first heating tube 21a and the second heating tube 21b are disposed on the first side of the connecting plate 221 and are respectively connected to a through hole 2211. The connecting seat 222 is provided with a through groove 2221 on the side facing the connecting plate 221. The connecting seat 222 is disposed on the second side of the connecting plate 221 and covers the two through holes 2211. The through groove 2221 connects the first heating tube 21a and the second heating tube 21b through the two through holes 2211.

[0072] It is understood that the first heating tube 21a and the second heating tube 21b are located on the same side of the connecting plate 221, and the connecting seat 222 can be located on the other side of the connecting plate 221. Two through holes 2211 are provided on the connecting plate 221. The first heating tube 21a and the second heating tube 21b are respectively connected to one through hole 2211 and to the through groove 2221 through the through holes 2211. Thus, the heating channels of the first heating tube 21a and the second heating tube 21b, together with the through groove 2221, constitute the liquid flow channel 201. At this time, the flow passage 22 is arranged in a block shape. Compared with a U-shaped connecting tube, this design is advantageous in further reducing the size of the flow passage 22 along the first direction, thereby reducing the overall height of the heater 20.

[0073] To improve the ease of connection between the first heating tube 21a and the second heating tube 21b and the connecting plate 221, a sealing flange is provided on the periphery of the connecting hole 2211 facing the first side. The first heating tube 21a and the second heating tube 21b are respectively inserted into the connecting hole 2211 or sleeved on the sealing flange, and are respectively sealed by welding, bonding, sintering, sealing ring or threading with the sealing flange.

[0074] To simplify the assembly process, the connecting plate 221 and the connecting seat 222 are sealed by welding, bonding, sintering, sealing ring, or threading.

[0075] Welded seals are formed by welding, and the weld seam forms a sealing barrier to prevent leakage of the heat exchange medium.

[0076] Adhesive sealing achieves a closed connection through the combined action of adhesives and sealants, preventing leakage of the heat exchange medium.

[0077] Sintered sealing involves densifying powder materials through a high-temperature sintering process to form structural components or coatings with sealing properties, thereby achieving a connection seal and preventing leakage of the heat exchange medium.

[0078] A sealing ring seal is a method of achieving a sealed connection by setting a sealing ring.

[0079] Threaded seals utilize the characteristics of threaded structures to achieve a sealing function. They prevent leakage of heat exchange media by using the radial pressure generated during threaded connection or the physical barrier formed by filling.

[0080] In another embodiment, the connecting plate 221 and the connecting seat 222 are integrally formed. This improves the structural strength and sealing performance of the connector, reduces assembly processes, and increases material utilization and production efficiency.

[0081] like Figure 7 As shown, in one embodiment, the heating area of ​​the heating part 212 on the outer peripheral wall of the tube body 211 is S, which satisfies: 45cm² 2 ≤S≤300cm 2 .

[0082] It is understandable that if the heating area S of the heating part 212 on the outer peripheral wall of the tube body 211 is less than 45 cm², 2 If the heating area is too small, it will be difficult to meet the heating power required by the heater 20; if the heating area S of the heating part 212 on the outer peripheral wall of the tube body 211 is greater than 300 cm², then the heating area is too small. 2 If the heating area is too large, it will result in redundant heating power, which is not conducive to reducing product costs. Furthermore, an excessively large heating area is also detrimental to the miniaturization of the heater 20. Specifically, the heating area S of the heating part 212 on the outer peripheral wall of the tube body 211 can be 45 cm².2 60cm 2 75cm 2 90cm 2 105cm 2 120cm 2 135cm 2 150cm 2 180cm 2 210cm 2 240cm 2 255cm 2 270cm 2 285cm 2 Or 300cm 2 Of course, it can also be any value within the above range.

[0083] like Figure 8 As shown, in one embodiment, the heating element 212 includes a first insulating layer 2121, a heating layer 2122, and a second insulating layer 2123. The first insulating layer 2121, the heating layer 2122, and the second insulating layer 2123 are sequentially stacked on the tube body 211 in a direction away from the tube body 211. The heating layer 2122 is electrically connected to the electronic control device. This configuration means that the heating element 212 employs thick-film heating technology, where the first insulating layer 2121, the heating layer 2122, and the second insulating layer 2123 are layered sequentially on the tube body 211 using screen printing technology. The heating layer 2122 can quickly respond to commands from the electronic control device, achieving rapid temperature rise. This rapid heating capability can significantly shorten the preheating time of the heater 20, improve battery start-up efficiency, and help the vehicle enter a stable operating state more quickly. The electrical connection between the heating layer 2122 and the electronic control device enables the heating element 212 to achieve precise temperature control, thereby ensuring that the thermal management system maintains the optimal operating temperature under different operating conditions, improving the operating efficiency and performance stability of the battery assembly. The first insulating layer 2121 and the second insulating layer 2123 are disposed on the inner and outer sides of the heating layer 2122, thereby providing reliable insulation protection for the heating layer 2122 and improving the reliability and safety of the heater 20.

[0084] In one embodiment, the thickness of the first insulating layer 2121 is T1, where 100μm ≤ T1 ≤ 200μm. This ensures both the protective effect of the first insulating layer 2121 and the thermal conductivity. The thickness of the first insulating layer 2121 can be 100μm, 110μm, 120μm, 130μm, 140μm, 150μm, 160μm, 170μm, 180μm, 190μm, 200μm, etc., or any value within the above range.

[0085] In one embodiment, the thickness of the heating layer 2122 is T2, where 10μm≤T2≤20μm. This ensures the heating effect of the heating layer 2122. The thickness of the heating layer 2122 can be 10μm, 11μm, 12μm, 13μm, 14μm, 15μm, 16μm, 17μm, 18μm, 19μm, 20μm, etc., or any value within the above range.

[0086] In one embodiment, the thickness of the second insulating layer 2123 is T3, where 30 ≤ T3 ≤ 80 μm. This provides sufficient protection for the heater 20 while reducing the thickness of the second insulating layer 2123. The thickness of the second heating layer 2122 can be 30 μm, 40 μm, 50 μm, 160 μm, 70 μm, 80 μm, etc., or any value within the above range.

[0087] like Figure 7 and Figure 8 As shown, in one embodiment, the length of the heating part 212 along the axial direction of the tube body 211 is L1, and the outer diameter of the tube body 211 is D1. L1 and D1 satisfy: 2≤L1 / D1≤20.

[0088] It is understandable that the ratio of L1 to D1 is greater than or equal to 2, meaning that the axial length of the heating section 212220 along the tube body 211 is at least twice the outer diameter of the tube body 211. This means the tube body 211 is essentially a strip-shaped tube, ensuring that the heat exchange medium flowing through the tube body 211 receives sufficient heating time to reach the required heating temperature. If the ratio of L1 to D1 is less than or equal to 20, because the heating area of ​​the heating section 212 is limited, if the axial length L1 of the heating section 212 along the tube body 211 increases, the corresponding circumferential width of the heating section 212 along the tube body 211 will inevitably decrease. This will also lead to a smaller diameter of the tube body 211, and consequently, a smaller flow cross-sectional area. Therefore, the flow cross-sectional area of ​​the tube body 211 may not meet the requirements. Furthermore, an excessively small flow cross-sectional area of ​​the tube body 211 may also cause redundant heating power, resulting in energy waste.

[0089] The ratio of the length L1 of the heating section 212 along the axial direction of the tube 211 to the outer diameter D1 of the tube 211 can be 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, etc., or any value within the above range. Optionally, 4 ≤ L1 / D1 ≤ 10.

[0090] like Figure 2 and Figure 5 As shown, in one embodiment, the heater 20 further includes a cover plate 23, which covers the shell port 102. The cover plate 23 has a through hole through which the heating tube 21 passes. The interface end 20a of the heater 20 is located on the side of the cover plate 23 away from the shell port 102.

[0091] The cover plate 23 can be used to cover the housing port 102 and simultaneously to fix the heater 20 inside the housing 10. The cover plate 23 can be integrally formed with the heating tube 21, or it can be separately formed and then assembled. The assembly methods between the heating tube 21 and the cover plate 23 include, but are not limited to, welding, bonding, sintering, snap-fitting, or screwing. Optionally, the heating tube 21 is vertically mounted on the cover plate 23. This arrangement makes the installation of the heating tube 21 more stable and less prone to shaking, thereby improving the stability of the welding. Of course, using other aforementioned processes for fixing and connecting also has the same effect, which will not be elaborated further here.

[0092] Optionally, the heating device 100 also includes a temperature detection component configured to detect the temperature of the heat exchange medium within the liquid flow channel 201.

[0093] like Figure 12 and Figure 13 As shown, this utility model also proposes a compressor integrated device 1000, including a compressor 200, a heating device 100, and a controller. The heater 20 of the heating device 100 is connected to the compressor 200; the controller is electrically connected to both the compressor 200 and the heater 20. The specific structure of the heating device 100 is as described in the above embodiments. Since this 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 elaborated here.

[0094] 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.

[0095] 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, a piston compressor, or a screw compressor, etc., and is not limited thereto.

[0096] The heater 20 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 heater 20 to the required temperature before being delivered to the battery via the circulation pipeline, thus heating the battery. Of course, heating the battery is just one example; the heat exchange media heated by the heater 20 in this solution can also be delivered to other locations in the vehicle, such as the engine and seats.

[0097] The controller is used to control the operation of the compressor 200 and the heater 20, such as controlling the start, stop, and speed adjustment of the motor 220 in the compressor 200, and controlling the start, stop, and heating power adjustment of the heater 20. The controller may include a circuit board and control chips mounted on that circuit board. The compressor 200 and heater 20 can be controlled by the same control chip. Alternatively, different control chips can be used to control the compressor 200 and heater 20 separately. In this case, the two control chips can be located on the same circuit board or on different circuit boards.

[0098] In this embodiment, the compressor integration device 1000 integrates the heater 20, compressor 200, and 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 heater 20 and the controller. Quick-connect fittings facilitate easy connection of the heater 20 to external pipelines, forming a closed circulation channel. The cross-section of the tube 211 along the direction perpendicular to the extension of the heating channel is a continuous and complete annular surface. 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 211 a complete annular wall in its circumferential direction, resulting in good sealing performance. In other words, the heating tube 21 has good sealing performance, and the heat exchange medium is less prone to leakage when flowing through the heating channel, thereby improving the sealing effect and reliability of the heating tube 21.

[0099] In the prior art, heaters 20 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. However, in this application, the tube body 211 of the heater 20 itself forms the heating channel, eliminating the need for multiple components to be joined together. This makes the heater 20 less prone to leakage and improves vehicle safety when applied to vehicles.

[0100] like Figure 13 As shown, in one embodiment, the compressor 200 includes a compression section 210 and a motor 220. The motor 220 is drivenly connected to the compression section 210, and the controller is electrically connected to the motor 220. The compressor 200 is provided with a refrigerant interface communicating with the compression section 210 and a circuit interface electrically connected to the controller. The motor 220 includes a rotating shaft 220a. The housing 10 of the heating device 100 has a first circumferential side facing the rotating shaft 220a and a second axial side facing the rotating shaft 220a. The housing port 102 is provided on the first side of the housing 10, and the second side of the housing 10 is connected to the outer shell of the compressor 200. The heater 20 is inserted into the receiving cavity 101 from the housing port 102.

[0101] like Figure 13 As shown, in one embodiment, the heater 20 includes a heating tube 21, and a heating channel is formed inside the heating tube 21. The motor 220 includes a rotating shaft 220a, and an angle α is formed between the center line of the heating channel and the rotation axis of the rotating shaft 220a, where α satisfies: 80°≤α≤100°.

[0102] This design, by limiting the included angle α, allows the air bubbles generated by the liquid to move upward naturally under the action of buoyancy when the liquid flows within the heating channel of the heating tube 21. This accelerates the expulsion of air bubbles from the heater 20, reducing the retention and / or accumulation of air bubbles within the heating channel. This ensures sufficient heating space within the heating channel and also improves the heat transfer efficiency of the heating tube 21, thereby increasing the heating efficiency of the heater 20. The value of the included angle α can be 80°, 82°, 84°, 86°, 88°, 90°, 92°, 94°, 96°, 98°, or 100°, or any value within the above range.

[0103] In one embodiment, α satisfies: 90°≤α≤100°. This configuration, where the centerline of the heating tube 21 is tilted away from the motor 220 (i.e., the heating tube 21 is offset away from the motor 220), gradually increases the distance between the end of the heating tube 21 (i.e., the interface end 20a of the heating device 100) and the compressor 200. This provides sufficient space for external piping to connect to the interface end 20a of the heating device 100 via the adapter 30, improving the ease of assembly of the compressor integrated device 1000. However, if α is greater than 100°, the heating tube 21 will be offset too much away from the motor 220, which is detrimental to the miniaturization of the compressor integrated device 1000.

[0104] like Figure 13 As shown, in one embodiment, the heater 20 further includes a cover plate 23 covering the shell port 102. The cover plate 23 has a through hole, through which the heating tube 21 passes. An included angle β is formed between the extended surface of the cover plate 23 and the rotation axis of the rotating shaft 220a, where β satisfies: 0°≤β≤10°.

[0105] It is understandable that the compressor integrated device 1000 is usually externally mounted during actual use, and water may splash onto the cover plate 23 during use, or water may drip from the vehicle frame onto the cover plate 23. In this embodiment, the rotation axis of the rotating shaft 220a is set in the horizontal direction, and the included angle β is between 0 and 10 degrees, that is, the extended surface of the cover plate 23 can be set in the horizontal direction, or it can be set at an angle relative to the horizontal plane. When the extended surface of the cover plate 23 is set at an angle relative to the horizontal plane, it can reduce the residue of water or other debris on the cover plate 23, which is beneficial to improving the sealing between the cover plate 23 and the housing 10, and reducing the heat loss caused by water absorbing the heat generated by the heating tube 21.
