Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a heat exchanger that can be used in automobiles. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers play an important role in chemical, petroleum, vehicle, food and many other industrial productions. For example, heat exchangers are widely used in the thermal management system of automobiles. Heat exchangers typically enable the exchange of heat between high-temperature water, low-temperature water, gaseous refrigerant, liquid refrigerant and oil.

[0003] Specifically, the heat exchanger usually has two sets of flow channels inside, which flow two different heat exchange media respectively. The heat exchanger has two pairs of fixed external connections. One pair of connections is connected to the inlet and outlet of one set of flow channels, and the other pair of connections is connected to the inlet and outlet of the other set of flow channels. The connections are used to connect the external pipelines to the corresponding flow channels inside the heat exchanger.

[0004] However, when heat exchangers are installed in different vehicle models, the layout of the thermal management circuits and the requirements for the interface direction are different. In the existing technology, heat exchangers are usually welded to the connectors and cannot be changed in direction. The same model of heat exchanger needs to be developed into a special version for different vehicle models, which increases the cost of mold development, as well as the difficulty of inventory management and assembly complexity. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the heat exchanger and the connector are fixedly connected in the prior art and cannot adapt to the requirements of different interface directions.

[0006] To solve the above-mentioned technical problems, the present invention discloses a heat exchanger, which includes a hollow shell and a connector connected to the shell, and a fluid channel is formed inside the shell.

[0007] One end of the connector forms a connecting part, and the housing has a mounting base with a mounting hole. The connecting part extends into the housing through the mounting hole of the mounting base and communicates with the corresponding fluid channel. The other end of the connector is used to communicate with an external pipeline.

[0008] Furthermore, the sidewall of the mounting hole is provided with multiple rotation limit positions. The connecting part can be fixed to the sidewall of the mounting hole in its circumferential direction at any of these rotation limit positions. By fixing the connecting part to the sidewall of the mounting hole in its circumferential direction at different rotation limit positions, the position of the connecting part relative to the sidewall of the mounting hole can be adjusted in the direction of rotation around the axis of the mounting hole. A cylindrical elastic seal is provided on the outer periphery of the connecting part. One end of the elastic seal is connected to the side of the mounting base near the fluid channel, and the other end is connected to the end of the connecting part near the fluid channel. The elastic seal can twist as the connecting head rotates.

[0009] Using the above technical solution, the internal fluid channel of this heat exchanger is connected to the external pipeline through the connector, which facilitates the heat exchange medium to enter the heat exchanger from the external pipeline for heat exchange. Furthermore, the mounting base of the heat exchanger is provided with multiple rotation limit positions on the side wall of the mounting hole. The connector can be assembled at any of the rotation limit positions through the connecting part, thereby adapting to the requirements of different interface directions and improving the applicability of the heat exchanger. For example, if the heat exchanger is used in one type of automobile, the connecting part of the connector can be assembled at one rotation limit position according to the installation space requirements, while if the heat exchanger is used in another type of automobile, the connecting part of the connector can be assembled at another rotation limit position according to the installation space requirements, thus eliminating the need to set up heat exchangers separately for different vehicle models.

[0010] Furthermore, a cylindrical elastic seal is provided on the outer periphery of the connector to ensure the sealing of the connector and the corresponding fluid channel at the connection. The elastic seal can rotate with the connector, so even if the rotation limit position of the connector on the mounting hole is changed, the sealing performance of the elastic seal will not be affected, thus meeting the sealing requirements of the connector when it is assembled at any rotation limit position.

[0011] The present invention also discloses a heat exchanger, wherein at least one protrusion is provided on the outer periphery of the connecting part, and the side wall of the mounting hole near the fluid channel is provided with a plurality of groove groups corresponding to a plurality of rotation limit positions, each groove group including at least one groove corresponding to at least one protrusion.

[0012] Each protrusion on the connecting part can engage with the corresponding groove of any groove group, so that the connecting part is fixed at the corresponding rotation limit position and the movement of the connecting part away from the housing along the axial direction of the mounting hole is restricted.

[0013] By adopting the above technical solution, at least one protrusion provided on the outer periphery of the connecting part can cooperate with the groove group corresponding to the rotation limit position to be assembled. This not only prevents the connector from circumferentially deflecting after being assembled at the predetermined rotation limit position, but also prevents the connecting part of the connector from detaching from the mounting hole, thereby improving the assembly stability between the connector and the mounting base of the housing.

[0014] The present invention also discloses a heat exchanger in which the elastic seal can extend and retract along the axial direction of the mounting hole, and an elastic element is provided in the housing at the corresponding position of the connecting part. The elastic element applies a pre-tightening force to the connecting part along the axial direction of the mounting hole toward the mounting seat, so that each protrusion on the connecting part is embedded and elastically abuts against the groove corresponding to any rotation limit position.

[0015] By adopting the above technical solution, the elastic element set in the housing can apply a pre-tightening force to the connecting part, ensuring that the connecting part will not easily move towards the housing along the axial direction of the mounting hole, preventing the protrusions on the connecting part from disengaging from the grooves at the corresponding rotation limit positions, and improving the assembly stability between the connecting part on the connector head and the corresponding mounting seat on the housing.

[0016] When it is necessary to adjust the position of the connector on the mounting base, pressure needs to be applied to the connector away from the mounting base along the axial direction of the mounting hole. The pressure should be sufficient to overcome the preload applied by the elastic element. The protrusions on the connector separate from the grooves at the corresponding rotation limit positions. Then, the connector is rotated around the axial direction of the mounting hole so that the protrusions on the connector are engaged with the grooves at another rotation limit position.

[0017] The present invention also discloses a heat exchanger in which the elastic seal is configured as a corrugated cylindrical structure. One end of the elastic seal is fixedly connected to the side wall of the mounting base near the fluid channel via a first circumferential fastener, and the other end is fixedly connected to the outer wall of the connecting part near the fluid channel via a second circumferential fastener.

[0018] The outer periphery of the connecting part is provided with a plurality of protrusions spaced apart in its circumferential direction, and each groove group includes a plurality of grooves that correspond one-to-one with the plurality of protrusions.

[0019] Using the above technical solution, the corrugated elastic seal can expand and contract along the axial direction of the mounting hole, and even if the connecting part moves along the axial direction of the mounting hole, it will not damage the elastic seal.

[0020] Furthermore, multiple protrusions are spaced apart on the outer periphery of the connecting part. When these protrusions mate with multiple grooves in the groove group, they can better restrict the rotation of the connecting part around the axis of the mounting hole, thereby improving the assembly stability between the connecting part and the mounting base.

[0021] The present invention also discloses a heat exchanger in which a first circumferential fastener is configured as a first clamp, which is sleeved on the side wall of the mounting base near the fluid channel and presses one end of the elastic seal onto the side wall of the mounting base near the fluid channel.

[0022] The second circumferential fastener is set as a second clamp, which is sleeved on the outer wall surface of the connection part and the fluid channel communication part, and presses the other end of the elastic seal on the outer wall surface of the connection part near the fluid channel.

[0023] By adopting the above technical solution, the mounting base is connected to the elastic seal, the elastic seal is connected to the connecting part and the fluid channel communication part by the first clamp and the second clamp respectively. This has the advantage of convenient assembly and improves the sealing performance of the elastic seal at the connection with other components.

[0024] The present invention also discloses a heat exchanger in which an assembly cavity extending along the axial direction of the mounting hole is formed at the corresponding position of the connection part inside the shell. The elastic element is a pre-compressed spring installed in the assembly cavity. One end of the spring is connected to the inner wall surface of the shell on the side away from the mounting seat, and the other end is connected to the end of the connection part near the fluid channel.

[0025] By adopting the above technical solution, the spring can apply a stable and continuous preload to the connector, and the protrusions on the connector will not easily disengage from the embedded groove.

[0026] The present invention also discloses a heat exchanger in which an axial limiting part for limiting an external pipeline is provided in the middle of the connector, the external pipeline is sleeved and fixed to the outer peripheral surface of the other end of the connector, and the end of the external pipeline abuts against the axial limiting part.

[0027] By adopting the above technical solution, the axial limiting part can play a limiting role in the assembly of external pipelines and connectors, thereby improving the assembly stability of external pipelines and connectors.

[0028] The present invention also discloses a heat exchanger, wherein the axial limiting part is configured as a limiting retaining ring that protrudes from the outer wall surface of the connector and surrounds the connector.

[0029] By adopting the above technical solution, the limiting retaining ring abuts against the corresponding end of the external pipeline, which not only restricts the axial movement of the external pipeline on the connector, but also reduces the risk of circumferential movement of the external pipeline sleeved on the outer periphery of the connector.

[0030] The present invention also discloses a heat exchanger in which a first fluid channel and a second fluid channel are formed independently within the shell. Two pairs of connectors are connected to the shell, one pair of connectors being connected and communicating with the outlet and inlet of the first fluid channel, respectively, and the other pair of connectors being connected and communicating with the outlet and inlet of the second fluid channel, respectively.

[0031] Furthermore, multiple heat exchange plates are spaced apart inside the shell, and two adjacent heat exchange plates are alternately arranged along the stacking direction to form a first fluid channel and a second fluid channel.

[0032] With the above technical solution, the outlets and inlets of the first and second fluid channels are connected to the corresponding external pipelines through connectors. The rotation limit position of any connector on the corresponding mounting base on the shell can be adjusted, which greatly improves the applicability of the heat exchanger. Furthermore, the two heat exchange media can smoothly enter the corresponding fluid channels of the heat exchanger through the connectors. The first and second fluid channels exchange heat with each other through multiple spaced heat exchange plates, which greatly improves the heat exchange efficiency.

[0033] The present invention also discloses an automobile that includes any of the above-mentioned heat exchangers.

[0034] By adopting the above technical solution, the fluid channel inside the heat exchanger is connected to the external pipeline through the connector, which facilitates the heat exchange medium to enter the heat exchanger from the external pipeline for heat exchange. Furthermore, the mounting base of the heat exchanger has multiple rotation limit positions on the side wall of the mounting hole. The connector can be assembled at any of the rotation limit positions through the connecting part, thereby adapting to different interface direction requirements, improving the applicability of the heat exchanger, and benefiting the space layout inside the car.

[0035] The beneficial effects of this utility model are as follows:

[0036] This utility model discloses a heat exchanger in which the internal fluid channel is connected to an external pipeline via a connector, facilitating the entry of the heat exchange medium from the external pipeline into the heat exchanger for heat exchange. Furthermore, the mounting base of the heat exchanger has multiple rotational limiting positions on the side wall of the mounting hole. The connector can be mounted at any of these rotational limiting positions via the connecting part, thus adapting to different interface orientation requirements and improving the applicability of the heat exchanger. Additionally, a cylindrical elastic seal is provided on the outer periphery of the connecting part to ensure the sealing performance between the connector and the corresponding fluid channel at the connection point. The elastic seal can twist as the connector rotates, so even if the rotational limiting position of the connecting part on the mounting hole is changed, the sealing performance of the elastic seal will not be affected, meeting the sealing requirements of the connecting part mounted at any of the rotational limiting positions.

[0050] As mentioned in the background section, when heat exchangers are installed in different vehicle models, the layout of the thermal management circuits and the interface direction requirements are different. In the prior art, heat exchangers are usually welded to the structure and cannot be changed in direction. The same model of heat exchanger needs to be developed into a special version for different vehicle models, which increases the cost of mold development, as well as the difficulty of inventory management and assembly complexity.

[0051] To address this issue, this invention provides a heat exchanger whose internal fluid channel is connected to an external pipeline via a connector, facilitating the entry of the heat exchange medium from the external pipeline. Furthermore, the heat exchanger's mounting base has multiple rotational limiting positions on the side wall of the mounting hole. The connector can be mounted at any of these positions, adapting to different interface orientation requirements and improving the heat exchanger's versatility. Even for vehicles with different spatial layouts, there is no need to redesign the heat exchanger; only the rotational limiting position of the connector within the mounting hole needs adjustment. Moreover, to enhance the heat exchanger's reliability and prevent leakage of the heat transfer medium between the connector and the housing, a cylindrical elastic seal is provided on the outer periphery of the connector. One end of the elastic seal is connected to the side of the mounting base near the fluid channel, and the other end is connected to the end of the connector near the fluid channel. The elastic seal can rotate with the connector, satisfying the sealing requirements of the connector at any of its rotational limiting positions.

[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0053] like Figure 1 As shown, this embodiment provides a heat exchanger 10, which includes a hollow shell 100 and a connector 200 connected to the shell 100. A fluid channel is formed inside the shell 100. Typically, the connector 200 connects the fluid channel inside the shell 100 to an external pipeline, thereby facilitating the entry of a heat transfer medium (e.g., cooling water or oil) from the external pipeline into the heat exchanger 10. The heat exchanger 10 typically exchanges heat between two heat transfer media; therefore, the shell 100 has a first fluid channel 120 (see...). Figure 2 ) and second fluid channel 130 (see Figure 2 Two different heat exchange media flow through them respectively. The two heat exchange media only exchange heat and do not flow into each other. That is to say, the first fluid channel 120 and the second fluid channel 130 are not connected to each other.

[0054] Both the first fluid channel 120 and the second fluid channel 130 have inlets and outlets, and the inlet and outlet of each fluid channel are connected to the corresponding external pipelines through connectors 200. Figure 1 Only the inlet and outlet of one set of fluid channels (first fluid channel 120) are shown. Since the connector 200 at each point is similar to the assembly structure of the housing 100, in the following text, it will be referred to as... Figure 1 The following explanation uses connector 200 at the inlet as an example.

[0055] Specifically, such as Figure 2 As shown, one end of the connector 200 forms a connecting portion 210 and is mounted on the housing 100 through the connecting portion 210, while the other end of the connector 200 extends in a bent manner relative to the connecting portion 210, thereby connecting to the external pipeline more smoothly.

[0056] The housing 100 has a mounting base 110. The upper surface of the mounting base 110 is a mating surface that mates with the connecting part 210. Therefore, the upper surface of the mounting base 110 protrudes from other outer surfaces of the housing 100 and has a higher machining precision than other outer surfaces of the housing 100. Furthermore, the mounting base 110 has a mounting hole 111. The connecting part 210 passes through the mounting hole 111 of the mounting base 110 and extends into the housing 100, communicating with a corresponding fluid channel. The sidewall of the mounting hole 111 has multiple rotational limiting positions. It should be noted that the sidewall of the mounting hole 111 can have two, three, four, or other numbers of rotational limiting positions; this embodiment does not specifically limit this. It should be noted that the sidewall of the mounting hole 111 can be understood as the area within the mounting base 110 that encloses the mounting hole 111.

[0057] The following is a detailed description of the specific assembly of the connector 200 and the mounting base 110 on the housing 100.

[0058] In this embodiment, the connecting part 210 can be fixed to the side wall of the mounting hole 111 in the circumferential direction at any rotational limiting position. Furthermore, by fixing the connecting part 210 to the side wall of the mounting hole 111 in the circumferential direction at different rotational limiting positions, the position of the connecting part 210 relative to the side wall of the mounting hole 111 can be adjusted in the direction of rotation around the axis of the mounting hole 111, thereby adapting to different interface direction requirements and improving the applicability of the heat exchanger 10. For example, if the heat exchanger 10 is used in one type of automobile, the connecting part 210 of the connector 200 can be assembled in one rotational limiting position according to the installation space requirements, while if the heat exchanger 10 is used in another type of automobile, the connecting part 210 of the connector 200 can be assembled in another rotational limiting position according to the installation space requirements, thus eliminating the need to set up the heat exchanger 10 separately for different vehicle models.

[0059] Furthermore, a cylindrical elastic seal 300 is provided on the outer periphery of the connecting part 210. One end of the elastic seal 300 is connected to the side of the mounting base 110 near the fluid channel, and the other end is connected to the end of the connecting part 210 near the fluid channel, ensuring the sealing of the connector 200 and the corresponding fluid channel at the connection. The elastic seal 300 can be twisted as the connector 200 rotates. Even if the rotation limit position of the connecting part 210 on the mounting hole 111 is changed, the sealing performance of the elastic seal 300 will not be affected, satisfying the sealing requirements of the connecting part 210 when it is assembled in any rotation limit position. This elastic seal 300 can be made of rubber or rubber combined with other materials. This embodiment does not make specific limitations on this.

[0060] To improve the assembly stability of the connector 200 and the mounting base 110 of the housing 100, that is, to ensure that the connector 210 does not deflect around the axis of the mounting hole 111 when it is engaged with any rotational limiting position of the mounting hole 111, therefore, in one embodiment, such as Figure 2 and Figure 3As shown, the outer periphery of the connecting portion 210 is provided with at least one protrusion 211. For example, the outer periphery of the connecting portion 210 may be provided with one, two, three, four or other numbers of protrusions 211. It should be noted that when multiple protrusions 211 are provided on the outer periphery of the connecting portion 210, the multiple protrusions 211 should be spaced apart along the circumference of the connecting portion 210. For example, when two protrusions 211 are provided, the two protrusions 211 are spaced 180° apart in the circumference of the connecting portion 210. When three protrusions 211 are provided, the two adjacent protrusions 211 are spaced 120° apart in the circumference of the connecting portion 210. When four protrusions 211 are provided, the two adjacent protrusions 211 are spaced 90° apart in the circumference of the connecting portion 210.

[0061] like Figure 2 and Figure 4 As shown, the sidewall of the mounting hole 111 near the fluid channel is provided with a plurality of groove groups corresponding to multiple rotation limit positions. When two rotation limit positions are provided on the mounting hole 111, two groove groups are provided on the sidewall of the mounting hole 111 near the fluid channel. When three rotation limit positions are provided on the mounting hole 111, three groove groups are provided on the sidewall of the mounting hole 111 near the fluid channel. When twelve rotation limit positions are provided on the mounting hole 111, twelve groove groups are provided on the sidewall of the mounting hole 111 near the fluid channel.

[0062] Furthermore, each groove group includes at least one groove 112 corresponding to at least one protrusion 211. For example, when one protrusion 211 is provided on the connecting part 210, each groove group includes one groove 112. When four protrusions 211 are provided on the connecting part 210, each groove group includes four grooves 112. It should be noted that the grooves 112 in different groove groups can all be set independently, or some can be shared and some can be set independently. This embodiment does not make specific limitations on this.

[0063] In this embodiment, each protrusion 211 on the connecting part 210 can engage with the corresponding groove 112 of any groove group, so that the connecting part 210 is fixed at the corresponding rotation limit position, preventing the connector 200 from circumferentially deflecting after being assembled at the predetermined rotation limit position. Moreover, after the protrusion 211 engages with the corresponding groove 112, it can restrict the movement of the connecting part 210 away from the housing 100 along the axial direction of the mounting hole 111, preventing the connecting part 210 of the connector 200 from detaching from the mounting hole 111, and improving the assembly stability between the connector 200 and the mounting base 110 of the housing 100.

[0064] It should be noted that, in this embodiment, the other end of the bent extension of the connector 200 can be assembled to the connector 210 by welding or gluing after the connector 210 is assembled with the mounting hole 111 of the mounting base 110. This embodiment does not make specific limitations on this.

[0065] Furthermore, in this embodiment, as Figure 2 As shown, an elastic element 400 is provided inside the housing 100 at the corresponding position of the connecting part 210. The elastic element 400 applies a preload force to the connecting part 210 along the axial direction of the mounting hole 111 toward the mounting base 110, so that each protrusion 211 on the connecting part 210 is embedded and elastically abuts against the groove 112 corresponding to any rotation limit position, ensuring that the connecting part 210 will not easily move toward the housing 100 along the axial direction of the mounting hole 111, and preventing each protrusion 211 on the connecting part 210 from disengaging from the groove 112 at the corresponding rotation limit position.

[0066] When it is necessary to adjust the position of the connector 200 on the mounting base 110, pressure needs to be applied to the connector 210 away from the mounting base 110 along the axial direction of the mounting hole 111. The pressure should be sufficient to overcome the preload applied by the elastic element 400. Each protrusion 211 on the connector 210 separates from the groove 112 at the corresponding rotation limit position. Then, the connector 210 is rotated about the axial direction of the mounting hole 111 so that each protrusion 211 on the connector 210 corresponds to and engages with the groove 112 at another rotation limit position.

[0067] Specifically, an assembly cavity 140 extending along the axial direction of the mounting hole 111 is formed in the housing 100 at the corresponding position of the connecting part 210. The elastic member 400 is a pre-compressed spring 410 installed in the assembly cavity 140. One end of the spring 410 is connected to the inner wall surface of the housing 100 on the side away from the mounting seat 110, and the other end is connected to the end of the connecting part 210 near the fluid channel. The spring 410 can apply a stable and continuous pre-tightening force to the connector 200, and the protrusions 211 on the connecting part 210 will not easily disengage from the embedded groove 112.

[0068] Of course, the structure of the elastic element 400 is not limited to the spring 410 in the above embodiment. It can also be a telescopic rod with a piston inside and which can extend and retract along the axial direction of the mounting hole 111. The telescopic rod has a compressed air chamber or a hydraulic chamber inside.

[0069] In this embodiment, since the connecting part 210 moves along the axial direction of the mounting hole 111 when adjusting the rotation limit position, in order to ensure the sealing reliability of the elastic seal 300, the elastic seal 300 can not only twist with the rotation of the connecting head 200, but also extend and retract along the axial direction of the mounting hole 111, so as to avoid being crushed or torn when the connecting part 210 moves along the axial direction of the mounting hole 111. Specifically, the elastic seal 300 can be set as a corrugated cylindrical structure. The corrugated elastic seal 300 can extend and retract along the axial direction of the mounting hole 111, so that even if the connecting part 210 moves along the axial direction of the mounting hole 111, it will not cause damage to the elastic seal 300. Of course, the elastic seal 300 can also be configured as a drum-shaped structure, that is, the diameter of the elastic seal 300 in the middle is much larger than the diameter of the two ends. When the connector 200 rotates or moves along the axial direction of the mounting hole 111, the redundant part in the middle of the elastic seal 300 is used to compensate for the pulling caused by the movement of the connector 200, and the elastic seal 300 can also be prevented from being damaged.

[0070] Furthermore, one end of the elastic seal 300 is fixedly connected to the side wall of the mounting base 110 near the fluid channel via the first circumferential fastener 310, and the other end is fixedly connected to the outer wall of the connecting part 210 near the fluid channel via the second circumferential fastener 320.

[0071] Specifically, the first circumferential fastener 310 is configured as a first clamp, which is fitted onto the side wall of the mounting base 110 near the fluid channel, pressing one end of the elastic seal 300 against the side wall of the mounting base 110 near the fluid channel. The second circumferential fastener 320 is configured as a second clamp, which is fitted onto the outer wall of the portion of the connecting part 210 that communicates with the fluid channel, pressing the other end of the elastic seal 300 against the outer wall of the connecting part 210 near the fluid channel. Of course, the circumferential fastener is not limited to clamps; it can also be a binding rope, which is used to tie the corresponding end of the elastic seal 300.

[0072] In this embodiment, the mounting base 110 is connected to the elastic seal 300, the elastic seal 300 is connected to the connecting part 210 and the fluid channel communication part by the first clamp and the second clamp respectively. This has the advantage of convenient assembly and improves the sealing performance of the elastic seal 300 at the connection with other components.

[0073] Of course, the two ends of the elastic seal 300 can not only be assembled by circumferential fasteners, but in another alternative embodiment, the two ends of the elastic seal 300 can be assembled by adhesive bonding.

[0074] Furthermore, the assembly of the connector 200 with the mounting base 110 of the housing 100 is not limited to the structure of the protrusion 211 and the groove 112 in the above embodiment. In another alternative embodiment, a blind hole is formed on the outer peripheral surface of the connector 210, and the mounting base 110 protrudes from the outer side wall of the housing 100. Multiple positioning holes are formed at positions corresponding to multiple rotation limit positions. Each positioning hole penetrates the side wall of the mounting base 110. When the connector 210 is assembled with any rotation limit hole, a fastener (such as a positioning pin or bolt) is passed through the corresponding positioning hole and connected with the blind hole on the connector 210. This can also improve the assembly stability of the connector 200 and the mounting base 110 of the housing 100.

[0075] The other structures on connector 200 are described below.

[0076] like Figure 3 As shown, the connector 200 not only needs to be connected to the mounting hole 111 of the corresponding mounting base 110 on the housing 100 through the connecting part 210, but the other end of the connector 200 also needs to be connected to the external pipeline. Therefore, an axial limiting part 220 for limiting the external pipeline is provided in the middle of the connector 200. The external pipeline is sleeved and fixed to the outer peripheral surface of the other end of the connector 200, and the end of the external pipeline abuts against the axial limiting part 220. The axial limiting part 220 can limit the assembly of the external pipeline and the connector 200, thereby improving the assembly stability of the external pipeline and the connector 200.

[0077] Specifically, the axial limiting part 220 is configured as a limiting ring 221 that protrudes from the outer wall surface of the connector 200 and surrounds the connector 200. The limiting ring 221 abuts against the end corresponding to the external pipeline, which not only restricts the axial movement of the external pipeline on the connector 200, but also reduces the risk of circumferential movement of the external pipeline sleeved on the outer periphery of the connector 200.

[0078] Of course, the axial limiting part 220 is not limited to the structure of the limiting ring 221. In another alternative embodiment, the axial limiting part 220 can also be set as multiple limiting protrusions on the outer periphery of the connector 200, such as two, three, or four limiting protrusions spaced apart on the outer periphery of the connector 200. Alternatively, the axial limiting part 220 can also be a limiting recess on the outer periphery of the connector 200, with the external pipeline engaging with the limiting recess on the connector 200 via protrusions. It should be noted that a sealing structure, such as a sealing ring, is also required at the connection between the external pipeline and the connector 200. This embodiment does not specifically limit this aspect.

[0079] The other structures on the housing 100 are described below.

[0080] Within the housing 100, the heat exchange medium in the first fluid channel 120 and the second fluid channel 130 needs to exchange heat. In one embodiment, a plurality of heat exchange plates 101 are spaced apart within the housing 100. For example, the housing 100 may be spaced apart with ten, thirteen, twenty, or other numbers of heat exchange plates 101. Two adjacent heat exchange plates 101 are alternately arranged along the stacking direction to form the first fluid channel 120 and the second fluid channel 130. The first fluid channel 120 and the second fluid channel 130 exchange heat with each other through the plurality of spaced heat exchange plates 101, which greatly improves the heat exchange efficiency.

[0081] Of course, in another alternative embodiment, the first fluid channel 120 and the second fluid channel 130 can also be configured as two double-helix extension pipes that surround each other, and the two heat exchange media exchange heat during the flow process. This embodiment does not specifically limit this.

[0082] The present invention also discloses an automobile, including any of the above-mentioned heat exchangers 10. Since the mounting base 110 of the heat exchanger 10 has multiple rotation limit positions on the side wall of the mounting hole 111, the connector 200 can be assembled at any rotation limit position through the connecting part 210, thereby adapting to different interface direction requirements, improving the applicability of the heat exchanger 10, and facilitating the space arrangement inside the automobile.
