[0031] With the development of the new energy vehicle industry and technological advancements, the thermal management systems of new energy vehicles are becoming increasingly complex. Among these systems, the heating device is a core component. In related technologies, the assembly structure of the heating device is complex, resulting in low assembly efficiency. For example, in some related technologies, the heating device includes a housing, a heater, and a connector. During assembly, the heater must first be installed inside the housing, then the connector is connected to the heater, and finally, the connector is secured to the housing with screws. The assembly process requires the use of tools to tighten the screws, making the assembly process cumbersome. Furthermore, tightening screws in a confined space presents considerable difficulty, leading to low assembly efficiency.

[0032] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art.

[0033] This utility model proposes a heating device 100, which aims to simplify the assembly structure of the heating device 100 and improve assembly efficiency.

[0034] Please see Figures 1 to 4 ,as well as Figure 6 In one embodiment of this utility model, the heating device 100 includes a housing 10, a heater 20, a quick-connect connector 30, and a snap-fit ​​member 40. The housing 10 has a receiving cavity 101 and a housing port 102 communicating with the receiving cavity 101; the heater 20 is disposed in the receiving cavity 101 and has a liquid flow channel 201; the quick-connect connector 30 is covered on the housing port 102 and is inserted into the heater 20, and the quick-connect connector 30 has a liquid flow channel 301 communicating with an external pipeline; the snap-fit ​​member 40 has a first snap-fit ​​part 41 and a second snap-fit ​​part 42 connected to each other, the first snap-fit ​​part 41 snaps into the quick-connect connector 30, and the second snap-fit ​​part 42 snaps into the housing 10 to lock the quick-connect connector 30 to the housing 10.

[0035] 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 housing port 102 communicating with the receiving cavity 101. The part of the heater 20 that mates with the quick-connect connector 30 faces the housing port 102 or extends out of the housing port 102. When the quick-connect connector 30 is assembled with the heater 20 and the housing 10, the quick-connect connector 30 can close the housing port 102 to form a sealed cavity inside 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.

[0036] 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 includes, but is not limited to, tubular heaters, plate heaters, or other types of heaters, as long as a liquid flow channel 201 for liquid circulation 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 includes, but is not limited to, straight channels, curved channels, or other irregularly shaped 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, so that the heater 20 as a whole has a U-shaped structure, and correspondingly, the liquid flow channel 201 has a U-shaped flow channel.

[0037] The quick-connector 30 has a hollow structure with a liquid flow channel 301 inside. The quick-connector 30 serves as a bridge connecting the heater 20 to external pipelines. After the quick-connector 30 is assembled with the housing 10 and the heater 20, the liquid flow channel 301 of the quick-connector 30 connects to the liquid flow channel 201 of the heater 20. The outlet end of the quick-connector 301 can be quickly plugged into an external pipeline, thereby connecting the heater 20 to the external pipeline. The quick-connector 30 covers the housing port 102 and is plugged into the heater 20. The quick-connector 30 can be used as a female end for insertion into the end of the heater 20, or it can be used as a male end, partially inserted into the heater 20, as long as the liquid flow channel 201 and the liquid flow channel 301 are connected while ensuring reliable sealing.

[0038] To ensure assembly reliability, the heating device 100 also includes a snap-fit ​​component 40, which has a first snap-fit ​​portion 41 and a second snap-fit ​​portion 42 that are interconnected. When the quick-connect fitting 30 is placed on the housing port 102 and inserted into the heater 20, the first snap-fit ​​portion 41 of the snap-fit ​​component 40 is snapped into the quick-connect fitting 30, and the second snap-fit ​​portion 42 of the snap-fit ​​component 40 is snapped into the housing 10. In this way, the snap-fit ​​component 40 can lock the quick-connect fitting 30 to the housing 10, thereby preventing the quick-connect fitting 30 from becoming loose and causing leakage. Furthermore, when the heating device 100 needs to be disassembled for maintenance, the snap-fit ​​component 40 can be easily released from the housing 10 and the quick-connect fitting 30, improving maintenance convenience. The number of snap-fit ​​components 40 can be set according to actual needs, and can be one, two, or more. Optionally, at least two snap-fit ​​connectors 40 are provided, and the quick-connect connector 30 can be locked to the housing 10 by at least two snap-fit ​​connectors 40, which can further improve assembly reliability.

[0039] The heating device 100 of this utility model includes a housing 10, a heater 20, a quick-connect connector 30, and a snap-fit ​​component 40. During assembly, the heater 20 is placed inside the receiving cavity 101 of the housing 10, and then the quick-connect connector 30 is placed over the shell port 102 of the housing 10 and inserted into the heater 20, thereby allowing the liquid flow channel 201 of the heater 20 to communicate with the liquid flow channel 301 of the quick-connect connector 30. After the quick-connect connector 30 and the heater 20 are assembled, the first snap-fit ​​part 41 of the snap-fit ​​component 40 engages with the quick-connect connector 30, and the second snap-fit ​​part 42 engages with the housing 10, thereby locking the quick-connect connector 30 to the housing 10 and preventing the quick-connect connector 30 from becoming loose and causing leakage. Compared to screw connections, the snap-fit ​​component 40 engages with both the quick-connect fitting 30 and the housing 10, resulting in a simpler assembly structure. Furthermore, no additional tools are required; operators can assemble the snap-fit ​​component 40 by hand, leading to higher assembly efficiency. This design simplifies the assembly structure of the heating device 100 and improves assembly efficiency.

[0040] Furthermore, in the thermal management system, when the heating device 100 is integrated with the compressor 200, the compressor 200 will vibrate during operation. If the quick-connect fitting and the housing are connected by screws, the screws are prone to loosening due to vibration, reducing reliability. This technical solution uses a snap-fit ​​fitting 40 instead of screws, which can improve assembly reliability.

[0041] like Figure 4 As shown, in order to further improve assembly convenience and assembly reliability, in one embodiment, the quick connector 30 is inserted into the heater 20 along the first direction, and the quick connector 30 is locked to the housing 10 by a snap-fit ​​member 40 on each of the opposite sides along the second direction, and the first direction and the second direction intersect.

[0042] In this embodiment, the shell port 102 is located at one end of the shell 10 along the first direction, for example, as Figure 8 As shown, when the housing 10 is placed upright, the first direction can be the height direction of the housing 10, and the housing port 102 is located at the top of the housing 10. The part of the heater 20 that mates with the quick-connect connector 30 faces the housing port 102. Thus, when the quick-connect connector 30 is closed onto the housing port 102 from top to bottom along the first direction, the quick-connect connector 30 can also be inserted and mated with the heater 20 along the first direction, thereby achieving one-step assembly in the same direction and improving assembly efficiency. The quick-connect connector 30 is locked to the housing 10 by a snap-fit ​​member 40 on each of its opposite sides along the second direction, so that both sides of the quick-connect connector 30 can be limited, which can further improve the assembly reliability of the quick-connect connector 30, the housing 10, and the heater 20. The second direction can be the width direction of the housing 10 (e.g., the left-right direction).

[0043] like Figures 4 to 6 As shown, in one embodiment, the snap-fit ​​member 40 includes a first snap-fit ​​portion 41 and a second snap-fit ​​portion 42 that are opposite to and spaced apart, and an elastic portion 43 that connects the first snap-fit ​​portion 41 and the second snap-fit ​​portion 42. The quick-connect connector 30 has a first mating portion 31, and the housing 10 has a second mating portion 11. The first snap-fit ​​portion 41 is snap-fitted with the first mating portion 31, and the second snap-fit ​​portion 42 is snap-fitted with the second mating portion 11.

[0044] In this embodiment, the first latching portion 41 and the second latching portion 42 are positioned opposite each other and spaced apart, and connected by an elastic portion 43. Under external force, the elastic portion 43 can deform, causing the distance between the first latching portion 41 and the second latching portion 42 to change. This facilitates the assembly or disassembly of the latching member 40 with the housing 10 and the quick-connect connector 30, and improves assembly reliability. For example, during assembly, the elastic portion 43 can be stretched to increase the distance between the first latching portion 41 and the second latching portion 42, facilitating assembly. Once assembled, the first latching portion 41 and the second latching portion 42 tend to move closer together under the action of the elastic portion 43, causing the first latching portion 41 to abut against the first mating portion 31 and the second latching portion 42 to abut against the second mating portion 11, thereby improving assembly reliability. When disassembly is required, external force can be applied again to increase the distance between the first latching portion 41 and the second latching portion 42, facilitating disassembly.

[0045] For example, the first latching portion 41 and the second latching portion 42 are arranged opposite to each other and spaced apart along a first direction, and the first mating portion 31 and the second mating portion 11 are arranged opposite to each other and spaced apart along a second direction. Figure 7 As shown, when the snap-fit ​​component 40 is in its natural state (i.e., the initial state in which the snap-fit ​​component 40 is not assembled with other components), there is a first preset distance between the first snap-fit ​​portion 41 and the second snap-fit ​​portion 42; as Figure 7 As shown, when the snap-fit ​​member 40 is in the working state (that is, when the snap-fit ​​member 40 locks the quick-connect connector 30 to the housing 10), the elastic part 43 undergoes elastic deformation and elongates. At this time, there is a second preset distance between the first snap-fit ​​part 41 and the second snap-fit ​​part 42, which is greater than the first preset distance. In the working state, the elastic part 43 of the snap-fit ​​member 40 has elastic potential energy and can provide a rebound force, so that the first snap-fit ​​part 41 and the second snap-fit ​​part 42 tend to move closer to each other in the first direction, thereby enabling the first snap-fit ​​part 41 to abut against the first mating part 31 and the second snap-fit ​​part 42 to abut against the second mating part 11.

[0046] like Figure 4As shown, in order to further improve assembly reliability, the first mating part 31 is provided with a first slot 311 that is open on the side opposite to the housing 10, and the second mating part 11 is provided with a second slot 111 that is open on the side opposite to the quick connector 30. The first snap-fit ​​part 41 snaps into the first slot 311, and the second snap-fit ​​part 42 snaps into the second slot 111.

[0047] In this embodiment, the first snap-fit ​​part 41 is snapped into the first snap-fit ​​groove 311. The groove wall of the first snap-fit ​​groove 311 can limit the first snap-fit ​​part 41 and prevent the first snap-fit ​​part 41 from loosening from the first mating part 31. The second snap-fit ​​part 42 is snapped into the second snap-fit ​​groove 111. The groove wall of the second snap-fit ​​groove 111 can limit the second snap-fit ​​part 42 and prevent the second snap-fit ​​part 42 from loosening from the second mating part 11. In this way, the assembly of the snap-fit ​​part 40 with the housing 10 and the quick-connect connector 30 can be more stable and reliable, thereby further improving the assembly reliability of the quick-connect connector 30 and the heater 20.

[0048] For example, the quick-connect connector 30 includes a base 32 and a liquid-passing pipe 33 disposed on one side of the base 32. The side of the base 32 facing away from the liquid-passing pipe 33 covers the shell port 102 of the housing 10 along a first direction. The liquid-passing pipe 33 is inserted into the heating tube 21 of the heater 20 along the first direction. The base 32 has a first mating part 31 on each of its opposite sides along a second direction. The side of the first mating part 31 facing away from the housing 10 has a first slot 311, which is a through groove extending along a third direction. The housing 10 includes a housing body and a second mating part 11 protruding from the peripheral wall of the housing body. The second mating part 11 is disposed on the housing body near the shell port 102. The side of the second mating part 11 facing away from the quick-connect connector 30 has a second slot 111, which is a through groove extending along a third direction. The first engaging portion 41 and the second engaging portion 42 of the latching member 40 are arranged opposite each other along the first direction and are strip-shaped extending in the third direction, so that they can be easily latched into the corresponding slots. Furthermore, the groove walls of the first slot 311 and the second slot 111 can restrict the movement of the latching member 40 along the second direction. The first direction, the second direction, and the third direction intersect each other.

[0049] Furthermore, such as Figure 5 and Figure 6As shown, the first latching portion 41 has a first latching side 411 facing the second latching portion 42, and the second latching portion 42 has a second latching side 421 facing the first latching portion 41. The vertical distance between the first latching side 411 and the second latching side 421 is d1. The first slot 311 has a first stop side 311a that contacts the first latching side 411, and the second slot 111 has a second stop side 111a that contacts the second latching side 421. The vertical distance between the first stop side 311a and the second stop side 111a is d2. When the latching member 40 is in its natural state, the following condition is met: d1 is not greater than d2.

[0050] In this embodiment, when the snap-fit ​​component 40 is in its natural state (i.e., the initial state in which the snap-fit ​​component 40 is not assembled with other components), d1 equals d2, or d1 is less than d2. After the snap-fit ​​component 40 is assembled with the quick-connect connector 30 and the housing 10, the first snap-fit ​​side 411 of the first snap-fit ​​portion 41 contacts the first stop side 311a of the first slot 311, and the second snap-fit ​​side 421 of the second snap-fit ​​portion 42 contacts the second stop side 111a of the second slot 111. If d1 equals d2 when the snap-fit ​​component 40 is in its natural state, the elastic portion 43 does not deform after the snap-fit ​​component 40 is assembled. Since the first slot 311 and the second slot 111 have a certain depth, the snap-fit ​​portion can be prevented from loosening by the limiting effect of the first slot 311 and the second slot 111. When the snap-fit ​​40 is in its natural state, if d1 is less than d2, the elastic part 43 will be stretched after the snap-fit ​​40 is assembled in place. The elastic part 43 generates a rebound force, which makes the first snap-fit ​​side 411 and the second snap-fit ​​side 421 tend to move closer to each other. Thus, under the action of the elastic force of the elastic part 43, the first snap-fit ​​side 411 can be pressed against the first stop side 311a, and the second snap-fit ​​side 421 can be pressed against the second stop side 111a, which makes the assembly of the snap-fit ​​40 more stable and reliable.

[0051] like Figure 6 As shown, in one embodiment, the first snap-fit ​​portion 41 is configured as a first stop 41a, and the second snap-fit ​​portion 42 is configured as a second stop 42a. The first stop 41a and the second stop 42a are arranged opposite to each other and spaced apart along a first direction, and extend along a third direction respectively. The snap-fit ​​member 40 also includes two elastic portions 43 that are arranged opposite to each other and spaced apart along a third direction. The first stop 41a, one elastic portion 43, the second stop 42a, and the other elastic portion 43 are connected end to end to form a closed loop structure, and the first direction intersects with the third direction.

[0052] In this embodiment, the first direction can be the insertion direction of the quick-connect connector 30 and the heater 20 (e.g., the up-down direction), and the third direction can be the thickness direction of the housing 10 (e.g., the front-back direction). The first snap-fit ​​portion 41 is constructed as a slender first stop 41a, which facilitates assembly into the first slot 311, and the second snap-fit ​​portion 42 is constructed as a slender second stop 42a, which facilitates assembly into the second slot 111. The first stop 41a, one elastic portion 43, the second stop 42a, and the other elastic portion 43 are connected end to end in sequence, so that the snap-fit ​​member 40 is constructed as a closed ring structure. For example, the snap-fit ​​member 40 can be a U-shaped snap spring. The two elastic portions 43 of the snap-fit ​​member 40 are respectively provided on both sides of the snap-fit ​​member 40, so that the snap-fit ​​member 40 is subjected to more uniform force when elastic deformation occurs. And when the snap-fit ​​member 40 is assembled with the housing 10 and the quick-connect connector 30, the elastic portions 43 on both sides can also play a limiting role to prevent the snap-fit ​​member 40 from loosening along the third direction. Of course, in some embodiments, the elastic part 43 may be provided only on one side, so that the snap-fit ​​member 40 is constructed as a non-closed-loop structure similar to the shape of an inverted circle.

[0053] In one embodiment, each elastic portion 43 includes a plurality of elastic segments arranged and connected along a first direction, at least some of which are configured as convex arc segments protruding toward the side away from another elastic portion 43. The number of elastic segments can be two, three, or more. The convex arc segments, which provide stable elastic force and control the direction of deformation, can provide stable elastic force. Optionally, all of the multiple elastic segments are configured as convex arc segments protruding toward the side away from another elastic portion 43, resulting in smoother force distribution and higher reliability.

[0054] like Figure 7 As shown, in one embodiment, the elastic portion 43 includes a first elastic segment 431 and a second elastic segment 432 arranged at an angle. The end of the first elastic segment 431 away from the second elastic segment 432 is connected to a first retaining edge 41a, and the end of the second elastic segment 432 away from the first elastic segment 431 is connected to a second retaining edge 42a. The first elastic segment 431 and the second elastic segment 432 are arranged at an angle, and the portion where the first elastic segment 431 and the second elastic segment 432 meet protrudes towards the side away from the other elastic portion 43. The first elastic portion 43 and the second elastic portion 43 are bent and connected, so that the elastic portion 43 is constructed with a V-shaped structure. In this way, the elastic portion 43 can achieve a large stroke within a limited space and can provide a continuous and stable elastic force. Furthermore, during assembly, only the protruding portion of the elastic portion 43 needs to be squeezed to deform the elastic portion 43, thereby increasing the distance between the first retaining edge 41a and the second retaining edge 42a, which facilitates the assembly of the snap-fit ​​member 40.

[0055] Furthermore, such as Figure 7As shown, each elastic section 43 also includes a third elastic section 433 connecting the first elastic section 431 and the second elastic section 432. The third elastic section 433 is a convex arc segment that protrudes toward the side away from the other elastic section 43. The first elastic section 431 and the second elastic section 432 are transitionally connected by the arc-shaped third elastic section 433, which can eliminate stress concentration, achieve smooth deformation, and thus greatly improve fatigue life and stability.

[0056] In one embodiment, the angle between the first elastic segment 431 and the first stop 41a is a right angle or an obtuse angle. That is, the angle between the first elastic segment 431 and the first stop 41a is α, which satisfies 90°≤α<180°. For example, the angle α between the first elastic segment 431 and the first stop 41a can be 90°, 100°, 120°, 135°, 150°, 175°, or any value within the above range.

[0057] In one embodiment, the angle between the second elastic segment 432 and the second stop 42a is a right angle or an obtuse angle. That is, the angle between the second elastic segment 432 and the second stop 42a is β, which satisfies 90° ≤ β < 180°. For example, the angle β between the second elastic segment 432 and the second stop 42a can be 90°, 100°, 120°, 135°, 150°, 175°, or any value within the above range.

[0058] like Figure 4 and Figure 12 As shown, in some embodiments, the heater 20 has a port portion 20a that extends out of the housing 10 from the housing port 102. The quick-connect fitting 30 is sleeved around the port portion 20a. A sealing member 50 is provided between the quick-connect fitting 30 and the port portion 20a. The sealing member 50 is used to seal the port portion 20a and the quick-connect fitting 30 together.

[0059] In this embodiment, the port portion 20a of the heater 20 extends out of the housing 20 to engage with the quick-connect connector 30. For example, the quick-connect connector 30 may include a quick-connect portion 331 and a lead-out portion 332. The quick-connect portion 331 has a quick-connect opening 302, and the port portion 20 can be inserted into the quick-connect portion 311 of the quick-connect connector 30 through the quick-connect opening 302. The heater 20 may include a heating tube 21, and the tube end 21a of the heating tube 21 can serve as the port portion 20a of the heater 20. To further ensure sealing reliability and reduce the risk of leakage, a sealing element 50 is provided between the quick-connect connector 30 and the port portion 20a. The sealing element 50 can seal the quick-connect connector 30 and the port portion 20a, ensuring sealing performance and preventing liquid in the heater 20 from leaking from the gap between the port portion 20a and the quick-connect connector 30. The sealing element 50 includes, but is not limited to, sealant, sealing rings, or sealing tape. For example, the sealing element 50 may be a sealing ring made of rubber or silicone.

[0060] The seal 50 can be used to achieve radial sealing or end-face sealing between the port portion 20a and the quick-connect fitting 30. Furthermore, the number of seals 50 can be set to one or more as needed.

[0061] In one embodiment, the sealing member 50 is disposed between the outer peripheral wall of the port portion 20a and the inner peripheral wall of the quick connector 30; and / or, the inner wall of the quick connector 30 is provided with a stepped surface 30a opposite to the end face of the port portion 20a, and the sealing member 50 is disposed between the end face of the port portion 20a and the stepped surface 30a.

[0062] For example, such as Figure 4 As shown, the seal 50 is disposed between the outer peripheral wall of the port portion 20a and the inner peripheral wall of the quick-connect fitting 30. Thus, the outer peripheral wall of the port portion 20a and the inner peripheral wall of the quick-connect fitting 30 jointly compress the seal 50, causing it to deform and thereby sealingly connecting the outer peripheral wall of the port portion 20a and the inner peripheral wall of the quick-connect fitting 30, achieving a radial seal between them. Optionally, the seal 50 is an O-ring.

[0063] Optionally, the inner peripheral wall of the quick-connect connector 30 is provided with an annular sealing groove 322, and the sealing element 50 is installed in the sealing groove 322. When the end 21a of the heating tube 21 is inserted into the quick-connect port 302, the outer wall of the heating tube 21 presses against the sealing element 50, causing the sealing element 50 to deform, thereby achieving a reliable sealing connection. Of course, in some embodiments, the sealing element 50 can also be sleeved on the outer periphery of the port portion 20a, or an annular sealing groove 322 for accommodating the sealing element 50 can be formed on the outer peripheral wall of the port portion 20a.

[0064] For example, such as Figure 12As shown, the inner peripheral wall of the quick-connect fitting 30 has a stepped surface 30a opposite to the end face of the port portion 20a. The sealing member 50 is disposed between the end face of the port portion 20a and the stepped surface 30a. Thus, the end face of the port portion 20a and the stepped surface 30a of the quick-connect fitting 30 jointly compress the sealing member 50, causing it to deform and sealingly connecting the end face of the port portion 20a with the stepped surface 30a of the quick-connect fitting 30, achieving an end-face seal between them. Optionally, the sealing member 50 is a rectangular sealing ring.

[0065] Of course, a sealing element 50 can also be provided on the outer periphery of the port portion 20a and the end face of the port portion 20a respectively, so as to achieve both radial sealing and end face sealing with the quick connector 30, thereby achieving a double sealing effect.

[0066] like Figure 4 , Figures 9 to 11 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 end of each heating tube 21 facing away from the flow passage 22 is a tube end 21a. The quick-connect connector 30 includes a base 32 covering the shell port 102, and at least two liquid passages 33 disposed on the side of the base 32 away from the shell 10. Each liquid passage 33 is provided with a liquid flow channel 301. The base 32 has a mating surface 321 facing the shell port 102. Each liquid flow channel 301 has a quick-connect port 302 penetrating the mating surface 321. Each liquid flow channel 301 is provided with an outlet 303 at the end away from the quick-connect port 302. The tube end 21a of the heating tube 21 is inserted into the quick-connect port 302 one-to-one.

[0067] In this embodiment, during assembly, the mating surface 321 of the base 32 is placed over the shell port 102 of the housing 10, and the tube end 21a of the heating tube 21 is inserted into the quick-connect port 302 of the quick-connect connector 30, thereby achieving quick connection and assembly between the heating tube 21 and the quick-connect connector 30. Furthermore, one end of the quick-connect connector 30 with the outlet 303 can be used for quick connection and assembly with external pipelines, thereby improving assembly efficiency. In addition, since at least two liquid passage pipes 33 are integrated on the base 32, when assembling with at least two parallel heating tubes 21, only one pressing action is needed to simultaneously connect each quick-connect port 302 to the corresponding heating tube 21, without having to connect individual connectors to the corresponding heating tubes 21 one by one, simplifying the assembly steps and saving assembly time. Moreover, since at least two liquid passage pipes 33 are integrated on the base 32, the overall integration is higher, the structure is more compact, and it helps to reduce the space occupied.

[0068] like Figure 10 and Figure 11As shown, in one embodiment, each liquid passage 33 includes a quick-connect portion 331 and an outlet portion 332 connected to each other. The liquid passage 301 includes a first flow channel 3011 provided in the quick-connect portion 331 and a second flow channel 3012 provided in the outlet portion 332. The end of the first flow channel 3011 away from the second flow channel 3012 is provided with a quick-connect port 302, and the end of the second flow channel 3012 away from the first flow channel 3011 is provided with an outlet 303.

[0069] In this embodiment, the number of outlets 332 is the same as the number of quick-connect parts 331. The outlets 332 and quick-connect parts 331 are connected one-to-one. The second flow channel 3012 of the outlet 332 communicates with the first flow channel 3011 of the quick-connect part 331 to form a liquid flow channel 301, allowing the fluid in the heating tube 21 to be transported to the external pipeline via the first flow channel 3011, the second flow channel 3012, and then through the outlet 303. The outlets 332 and quick-connect parts 331 can be integrally formed or assembled. Optionally, the outlets 332 and quick-connect parts 331 are integrally formed to simplify the manufacturing process, improve structural strength, ensure the sealing reliability of the connection 34, and reduce the risk of leakage. The shape of the outlets 332 is not limited, and includes, but is not limited to, straight tubes, bent tubes, or other irregular tube shapes. Optionally, the outlet 332 is designed as a straight tube, which simplifies the structure and reduces the flow resistance of the fluid within the outlet 332.

[0070] The lead-out portion 332 can be customized according to different lead-out directions and insertion directions to meet different usage requirements. That is, the extension direction of the lead-out portion 332 can be designed to be consistent with or inconsistent with the extension direction of the quick-connect portion 331. For example, the axis of the lead-out portion 332 intersects the axis of the quick-connect portion 331, in which case the extension directions of the lead-out portion 332 and the quick-connect portion 331 are inconsistent. Intersection in this document includes perpendicular intersection or oblique intersection. Another example is that the axis of the lead-out portion 332 coincides with the axis of the quick-connect portion 331, in which case the lead-out portion 332 and the quick-connect portion 331 extend coaxially. Furthermore, the axis of the lead-out portion 332 can also be designed to be parallel to the axis of the quick-connect portion 331. In addition, the extension directions of different lead-out portions 332 can be consistent or inconsistent. The outlets 303 of different lead-out portions 332 can face the same side or different sides of the quick-connect connector; no specific limitation is made here.

[0071] In this embodiment, during assembly, each quick-connect part 331 can be simultaneously connected to its corresponding heating tube 21 through a single pressing action, eliminating the need to connect individual connectors to their respective heating tubes 21 one by one. This simplifies the assembly process and saves assembly time. Furthermore, the overall integration is higher, the structure is more compact, and it helps to reduce space occupation. The lead-out part 332 extends the fluid transport path within the quick-connect connector 30, allowing the outlet 303 to be positioned as far away from the housing 10 as possible. Thus, when the end of the lead-out part 332 with the outlet 303 is connected to an external pipeline, interference from the housing 10 with the installation of the external pipeline can be avoided, reducing the difficulty of installing the external pipeline and allowing for unrestricted pipeline layout. Moreover, the lead-out direction of the lead-out part 332 can be customized to maximize the center distance between the outlets 303 of two adjacent lead-out parts 332 for assembly with external pipelines. This effectively solves the problem of limited pipeline installation caused by an insufficient center distance between two parallel heating tubes 21.

[0072] To facilitate the connection of the quick-connect connector 30 to the external pipeline, each lead-out portion 332 is further provided with a connecting portion 34, which is used to connect to the external pipeline and to connect the lead-out portion 303 to the external pipeline.

[0073] There are various structures for the connector 34, which can be designed according to different pipeline structures. The assembly of the external pipeline and the connector 34 can be a jacket structure or an internal insertion structure.

[0074] For example, the connecting part 34 is configured as a upset head structure protruding from the outer peripheral surface of the lead-out part 332. When the external pipeline is a rubber hose, the upset head structure can be inserted into the external pipeline and can be interference-fitted with the inner wall of the external pipeline. Then, the external pipeline and the connecting part 34 can be locked together using a clamp.

[0075] For example, the connector 34 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 34 can be inserted into the female connector of the external pipeline for quick assembly. To improve versatility, the connector 34 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 34 may be configured as an SAE (Society of Automotive Engineers) male connector for insertion into an SAE female connector of an external pipeline.

[0076] For example, the connecting part 34 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 34 can be fitted over the male connector of the external pipeline to achieve quick assembly. To improve versatility, the connecting part 34 may optionally be configured as a VDA (Verbander Automobile Industry) female connector for plugging into and mating with the VDA male connector of the external pipeline.

[0077] Optionally, such as Figure 11 As shown, the extending direction of the quick-connect portion 331 intersects the extending direction of the outlet portion 332. For example, the quick-connect portion 331 extends vertically, and the outlet portion 332 extends laterally. The axis of the outlet portion 332 and the axis of the corresponding quick-connect portion 331 can intersect perpendicularly or obliquely. This design changes the fluid flow direction, allowing the outlet 303 to be located as far away from the housing 10 as possible, preventing interference from the housing 10 when connecting external pipes to the outlet 303. Furthermore, the direction of the outlet 303 changes compared to the outlet direction of the heating tube 21, facilitating easier connection to external pipes located radially to the heating tube 21.

[0078] Since the pipe wall of the liquid-passing pipe 33 will be subjected to a certain pressure when fluid passes through it, in order to improve the structural strength of the liquid-passing pipe 33, the quick-connect fitting 30 may optionally include a reinforcing rib 35 provided on the outer wall of the liquid-passing pipe 33. For example, when the quick-connect part 331 and the lead-out part 332 are bent and connected, the reinforcing rib 35 can be provided at the connection between the quick-connect part 331 and the lead-out part 332. In addition, the reinforcing rib 35 can also connect two adjacent quick-connect parts 331, or connect two adjacent lead-out parts 332, or connect the lead-out pipe to the base 32, so as to improve the overall structural strength of the quick-connect fitting 30.

[0079] like Figure 4 and Figure 10 As shown, in one embodiment, the heating tube 21 includes a tube body and a heating section. The tube body has a heating channel, and the cross-section of the tube body along the extension direction perpendicular to the heating 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.

[0080] The liquid flow channel 201 has an inlet and an outlet, with one liquid pipe 33 connected to the inlet and the other liquid pipe 33 connected to the outlet. The heating flow channels of at least two pipes constitute at least a portion of the liquid flow channel 201. 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. The liquid flow channel 201 in the heater 20 can be entirely composed of the heating flow channels of the heating pipe 21. In this case, the inlet for the heat exchange medium to flow into the heater 20 and the outlet for the heat exchange medium to flow out of the heater 20 are the openings of the heating pipe 21. Alternatively, an inlet connector and an outlet connector can be provided at the opening end 21a of the heating pipe 21. At this time, the heating channel of the heating tube 21 can form part of the liquid channel 201, and the liquid inlet channel in the liquid inlet connector and the liquid outlet channel in the liquid outlet connector can also form part of the liquid channel 201. The liquid inlet and liquid outlet can be respectively provided in the liquid inlet connector and the liquid outlet connector. When the tube end 21a of the heating tube 21 is provided with a liquid inlet connector and a liquid outlet connector, the quick-connect part 331 of the quick-connect connector 30 is used to connect and cooperate with the liquid inlet connector or the liquid outlet connector.

[0081] 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 channel, the tube body can be a continuous and complete annular cross-section, so that the tube body can have a complete annular wall in the circumferential direction. 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.

[0082] To increase the heating area of ​​the heating section, reduce the volume of the heating tube 21, and improve the convenience of arranging the heating section, in one embodiment, the heating section 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 section uses a thick film heating method. Simultaneously, it also facilitates efficient heat transfer through the tube body for the heating section 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 section is located on the outer peripheral wall of the tube body and extends circumferentially along the tube body. That is, the heating section 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 section continuously surrounds the outer peripheral wall of the tube body; or, the heating section consists of multiple small heating elements spaced apart along the outer periphery of the tube body.

[0083] 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 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 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 at 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 20. 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 20.

[0084] like 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.

[0085] 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.

[0086] 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, or a screw compressor, etc., and is not limited thereto.

[0087] 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.

[0088] The controller is used to control the operation of the compressor 200 and the heater 20, such as controlling the starting, stopping, and speed adjustment of the motor in the compressor 200, and controlling the starting, stopping, 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.

[0089] 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 body 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 body 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.

[0090] 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 heating channel is formed by the tube itself of the heater 20, 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.

[0091] This utility model 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.

[0092] This utility model 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.

[0093] 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.

[0094] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
