[0033] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The embodiment of this application provides a heat exchanger, which can adjust the flow rate of the heat exchange medium between different heat exchange components through a regulating valve, thereby adjusting the temperatures of different heat exchange zones corresponding to different heat exchange components and realizing the functions of different temperature zones.

[0035] The heat exchanger provided by this application will be further described in detail below with reference to the drawings and specific embodiments.

[0036] Refer to Figure 1 , which shows a schematic structural diagram of the heat exchanger according to the embodiment of this application, as Figure 1As shown in the figure, the heat exchanger provided by the embodiment of the present application may include: a plurality of heat exchange components 10 and a regulating valve 40. Among them, a heat exchange medium can be introduced into the heat exchange components 10 and is used for the circulation of the heat exchange medium. The regulating valve 40 is arranged between adjacent heat exchange components 10 and is respectively communicated with the plurality of heat exchange components 10. The regulating valve 40 is used to control the entry of the heat exchange medium into the heat exchange components 10. At the same time, by controlling the regulating valve 40, it can be used to adjust the flow rate or flow velocity of the heat exchange medium entering the plurality of heat exchange components 10 from the regulating valve 40. When the flow rate or flow velocity of the heat exchange medium in the plurality of heat exchange components 10 is different, different temperatures can be achieved between different heat exchange components 10, thereby realizing the multi-temperature zone function of the heat exchanger.

[0037] Further, the plurality of heat exchange components 10 are arranged at intervals along the first direction x. The heat exchanger further includes a first manifold 20 and a second manifold 30 extending along the first direction x. The plurality of heat exchange components 10 are connected between the first manifold 20 and the second manifold 30. In practical applications, the first manifold 20 can be used to introduce the heat exchange medium into the heat exchange components 10, and the second manifold 30 can be used to export the heat exchange medium in the heat exchange components 10. Among them, the regulating valve 40 is arranged in the first manifold 20. The regulating valve 40 is located between adjacent heat exchange components 10, and the regulating valve 40 is used to adjust the flow rate of the heat exchange medium introduced from the first manifold 20 into the adjacent heat exchange components 10.

[0038] Specifically, the first manifold 20 and the second manifold 30 may extend along the first direction x and are arranged at intervals along the second direction y, presenting a substantially parallel state. A heat exchange flow path for the circulation of the heat exchange medium is provided in the heat exchange component 10, and the heat exchange flow path in the heat exchange component 10 includes two ends arranged away from each other along the second direction y. Among them, one end of the heat exchange flow path is communicated with the first manifold 20, and the other end is communicated with the second manifold 30, so that the heat exchange flow path forms a one-way flow path. That is, the heat exchange medium enters the heat exchange flow path from the first manifold 20 and flows into the second manifold 30 after passing through the heat exchange flow path. When the heat exchange medium in the heat exchange flow path is in a continuous flow state, the function of heat exchange between the heat exchange component 10 and the surrounding environment can be realized.

[0039] Among them, the heat exchange medium includes but is not limited to air, water, steam, refrigerant, heat-conducting oil, etc. The heat exchange medium can exchange heat with the surrounding environment of the heat exchanger to adjust the environmental temperature.

[0040] The regulating valve 40 is disposed within the first header 20 and is located at a position between adjacent heat exchange modules 10. The two sides of the regulating valve 40 along the first direction x are respectively communicated with the two sides of the first header 20, so that the heat exchange medium can be split from the regulating valve 40 into the first headers 20 on both sides of the regulating valve 40, and the heat exchange medium is transported through the first headers 20 into the heat exchange flow channels of the heat exchange modules 10 to exchange heat with the external environment, thereby realizing the temperature regulation function. In the embodiment of the present application, the regulating valve 40 can be used to regulate the flow rate of the heat exchange medium flowing from the first header 20 into the adjacent heat exchange modules 10. It can be understood that since the cross-sectional area of the heat exchange flow channels between adjacent heat exchange modules 10 is constant, when the flow rates of the heat exchange medium between adjacent heat exchange modules 10 are different, the greater the flow rate, the faster the flow velocity of the heat exchange medium, which is beneficial to improving the heat exchange efficiency between the heat exchange medium and the external environment.

[0041] In addition, when adjacent heat exchange modules are arranged at intervals, air can be used as the heat insulation medium, and the heat transfer and heat exchange between adjacent heat exchange modules can be reduced, strengthening the multi-temperature zone control effect.

[0042] Exemplarily, when a cooling medium is introduced into the heat exchange module 10 to cool the environment, when the flow rate of the cooling medium is large, its flow velocity is faster, the cooling efficiency is higher, the temperature change of the temperature zone corresponding to the heat exchange module 10 is greater, and the actual temperature is lower, while on the side where the flow of the cooling medium is relatively small, the cooling efficiency is low, the temperature change of the temperature zone corresponding to the heat exchange module 10 is small, and the actual temperature is higher; since different temperatures are achieved in the temperature zones corresponding to adjacent heat exchange modules 10, that is, the multi-temperature zone control function of the heat exchanger is realized.

[0043] It should be noted that in the embodiment of the present application, disposing the regulating valve 40 in the first header 20 can simplify the external structure of the heat exchanger, facilitate the spatial layout of the heat exchanger in the thermal management system or the vehicle. In addition, integrating the regulating valve 40 into the first header 20 can reduce the external interfaces and effectively reduce the risk of heat exchange medium leakage.

[0044] In addition, in order to increase the heat exchange area, the area of the heat exchange module 10 is usually relatively large, and adjacent heat exchange modules 10 are generally arranged continuously. In the embodiment of the present application, on the basis of adjusting the flow rate of the heat exchange medium entering the adjacent heat exchange modules 10 by adding the regulating valve 40 to realize different temperature zone control of different heat exchange modules 10, the adjacent heat exchange modules 10 are also arranged at intervals. It can be understood that air medium can actually be regarded as the heat insulation medium. Therefore, in this case, the heat transfer and heat exchange between adjacent heat exchange modules 10 can be effectively reduced, ensuring different temperatures between different heat exchange modules 10 and strengthening the multi-temperature zone control function of the heat exchanger.

[0045] In the embodiment of the present application, asFigure 3 As shown, a medium inlet 23 is further provided between adjacent heat exchange components 10 in the first header pipe 20. A regulating valve 40 is disposed at the medium inlet 23 and divides the first header pipe 20 into a first sub-header pipe 21 and a second sub-header pipe 22. Among them, the first sub-header pipe 21 is communicated with one of the adjacent heat exchange components 10, and the second sub-header pipe 22 is communicated with the other of the adjacent heat exchange components 10. The regulating valve 40 is respectively communicated with the medium inlet 23, the first sub-header pipe 21, and the second sub-header pipe 22.

[0046] Specifically, the medium inlet 23 is connected to a liquid inlet pipe. The regulating valve 40 is disposed at the medium inlet 23 and communicated with the liquid inlet pipe. The heat exchange medium can enter the regulating valve 40 through the liquid inlet pipe, and the regulating valve 40 divides the heat exchange medium and flows it into the first sub-header pipe 21 and the second sub-header pipe 22 that are communicated with the regulating valve 40.

[0047] Refer to Figure 2 , which shows a schematic diagram of the flow path of the heat exchange medium in the heat exchanger described in the embodiment of the present application. As Figure 2 shown, the heat exchange medium can enter the regulating valve 40 provided in the first header pipe 20 from the medium inlet 23, and the regulating valve 40 makes the heat exchange medium flow into the first sub-header pipe 21 and the second sub-header pipe 22 on both sides of the regulating valve 40 respectively. When the flow rates controlled by the regulating valve 40 flowing into the first sub-header pipe 21 and the second sub-header pipe 22 are different, different temperature zone control functions can be realized.

[0048] In the embodiment of the present application, the regulating valve 40 includes a liquid inlet, a first liquid outlet, and a second liquid outlet. Among them, the liquid inlet is communicated with the medium inlet 23, the first liquid outlet is communicated with the first sub-header pipe 21, and the second liquid outlet is communicated with the second sub-header pipe 22.

[0049] Specifically, the liquid inlet, the first liquid outlet, and the second liquid outlet of the regulating valve 40 may be provided with a first valve port, a second valve port, and a third valve port; the medium inlet 23 is connected to an external heat exchange medium input pipeline, and the liquid inlet of the regulating valve 40 is connected to the medium inlet 23. By controlling the opening or closing of the first valve port, the on-off between the heat exchange medium and the first manifold 20 can be controlled; when the first valve port is open, the heat exchange medium can enter the first manifold 20 through the regulating valve 40. After the heat exchange medium enters the regulating valve 40, by adjusting the opening degrees of the second valve port and the third valve port, the flow rates of the heat exchange medium entering the first sub-manifold 21 and the second sub-manifold 22 from the first liquid outlet and the second liquid outlet can be controlled respectively. This way of controlling the flow rate through the regulating valve 40 to achieve the multi-temperature zone control function of the heat exchanger has a simple structure and strong practicability. It should be noted that the opening degrees of the second valve port and the third valve port here include the range from fully closed to fully open. When one of the second valve port and the third valve port is fully closed, the heat exchange medium completely enters the first manifold through the other valve port, and at this time, the heat exchange component without heat exchange medium flow does not undergo a heat exchange process.

[0050] In the embodiment of the present application, the regulating valve 40 is a three-way proportional valve.

[0051] Optionally, the regulating valve 40 may be an electric three-way valve, a pneumatic three-way valve, or a hydraulic three-way valve. The present application does not specifically limit the control method of the three-way valve, and those skilled in the art can select according to actual usage requirements.

[0052] In some optional embodiments of the present application, the heat exchanger further includes a heat insulation layer 50, and the heat insulation layer 50 is disposed between adjacent heat exchange components 10 and at least partially separates adjacent heat exchange components 10.

[0053] Specifically, the dimension of the heat insulation layer 50 along the second direction y may be less than or equal to the distance between the first manifold 20 and the second manifold 30, so as to partially or completely separate adjacent heat exchange components 10. It should be noted that when the dimension of the heat insulation layer 50 along the second direction y is less than the distance between the first manifold 20 and the second manifold 30, the heat insulation layer 50 partially separates adjacent heat exchange components 10, and in this case, the heat insulation effect between adjacent heat exchange components 10 can also be achieved.

[0054] In practical applications, the heat insulation layer 50 may be a solid heat insulation member, or may be a hollow heat insulation cavity filled with a heat insulation medium. The heat insulation medium may be a gas or a liquid, and the present application does not specifically limit this.

[0055] Further, when the dimension of the heat insulation layer 50 along the second direction y is smaller than the distance between the first header 20 and the second header 30, the heat insulation layer 50 can be disposed on the side closer to the first header 20 along the second direction y. It can be understood that on the side closer to the first header 20, since the heat exchange medium just enters the heat exchange module 10 and the heat exchange with the external environment just begins, disposing the heat insulation layer 50 here can insulate between adjacent heat exchange modules 10 from the beginning stage of heat exchange to reduce heat exchange, which is beneficial to ensuring the subsequent heat exchange effect.

[0056] In some alternative embodiments of the present application, the heat insulation layer 50 includes two ends disposed away from each other along the second direction y, and the two ends of the heat insulation layer 50 are respectively connected to the first header 20 and the second header 30 to completely separate adjacent heat exchange modules 10 along the second direction y.

[0057] Specifically, the two ends of the heat insulation layer 50 are fixedly connected to the first header 20 and the second header 30. In practical applications, the heat insulation layer 50 can be bonded to the first header 20 and the second header 30, or the heat insulation layer 50 can also be welded to the first header 20 and the second header 30. Those skilled in the art can make a choice according to the specific material and dimensional relationship of the structure. The present application does not specifically limit the connection manner between the heat insulation layer 50 and the headers.

[0058] In some alternative embodiments of the present application, at least part of the two sides of the heat insulation layer 50 along the third direction is exposed outside the heat exchange module 10.

[0059] It can be understood that the dimension of the heat insulation layer 50 along the third direction can be larger than the dimension of the heat exchange module 10 along the third direction, so that adjacent heat exchange modules 10 can be completely separated along the third direction, enhancing the heat insulation effect of the heat insulation member between adjacent heat exchange modules 10.

[0060] In some alternative embodiments of the present application, the heat insulation layer 50 includes at least one of a fiberglass heat insulation layer 50, a rock wool heat insulation layer 50, a polyurethane foam heat insulation layer 50, and a silicate heat insulation layer 50.

[0061] Exemplarily, the heat insulation layer 50 can include one or more layers of heat insulation media. When there are multiple layers of heat insulation media, the materials of the multiple layers of heat insulation media can be the same or different. When the materials of the multiple layers of heat insulation media are the same, the heat insulation effect can be enhanced. When the materials of the multiple layers of heat insulation media are different, multiple different materials of heat insulation media are combined with each other to achieve different heat insulation effects. In addition, the setting manner of the heat insulation layer 50 can also be comprehensively considered in combination with the material cost and the heat insulation effect. The present application does not specifically limit this.

[0062] In the embodiment of the present application, the heat exchange assembly 10 includes a plurality of heat exchange tubes 11. The heat exchange tubes 11 extend along the second direction y, and the plurality of heat exchange tubes 11 are arranged at intervals along the first direction x. The second direction y intersects with the first direction x. Openings are provided at both ends of the heat exchange tube 11, and the openings at both ends are respectively communicated with the first header 20 and the second header 30.

[0063] Preferably, the heat exchange tube 11 is set as a flat tube, and its length direction is along the first direction x, the width direction is along the second direction y, and the thickness direction is along the second direction y. In practical applications, due to its flat shape, the flat tube is convenient for the overall layout of the heat exchanger. When the layout space of the heat exchanger is limited, more flat tubes can be arranged, so as to increase the heat exchange surface area. The heat exchange medium inside is close to the tube wall, which can improve the heat exchange efficiency. In addition, the flat tube can also provide a larger flow cross-sectional area and reduce the flow resistance of the heat exchange medium.

[0064] Furthermore, the heat exchange tube 11 can be selected as a composite aluminum tube to improve the heat exchange efficiency.

[0065] In the embodiment of the present application, as Figure 4 shown, the heat exchange assembly 10 further includes heat exchange fins 12, and the heat exchange fins 12 are connected between adjacent heat exchange tubes 11. In practical applications, the heat exchange fins 12 can be selected as aluminum foil fins and are connected to the heat exchange tubes 11 by brazing, which can improve the assembly efficiency between components.

[0066] It should be noted that adding heat exchange fins 12 between adjacent heat exchange tubes 11 can increase the heat exchange area of the heat exchange assembly 10, improve the heat exchange efficiency, thereby accelerating the adjustment speed of the ambient temperature and enhancing the user experience.

[0067] In the embodiment of the present application, a plurality of heat exchange fins 12 are arranged between adjacent heat exchange tubes 11, and the plurality of heat exchange fins 12 are arranged at intervals along the first direction x on the heat exchange tubes 11. The adjacent heat exchange fins 12 can be arranged at a preset angle, and the plurality of heat exchange fins 12 can be connected end to end to form a shape similar to a wavy line.

[0068] It can be understood that since arranging heat exchange fins 12 between adjacent heat exchange fins 12 can increase the heat exchange area of the heat exchange assembly 10, when a plurality of heat exchange fins 12 are arranged between adjacent heat exchange tubes 11, the heat exchange area can be further increased, thereby improving the heat exchange efficiency.

[0069] In the embodiment of the present application, a medium outlet 31 is provided on the second header 30, and the medium outlet 31 is arranged at the middle position of the second header 30 along the first direction x.

[0070] In practical applications, a liquid outlet pipe can be provided at the medium outlet 31. After the heat exchange medium flows from the heat exchange assembly 10 into the second manifold 30, the heat exchange medium can flow out of the heat exchanger uniformly through the liquid outlet pipe, and the heat exchange process of this part of the heat exchange medium ends. It can be understood that when the medium outlet 31 is arranged at the middle position of the second manifold 30 along the first direction x, the distances between the heat exchange channels of the heat exchange assemblies 10 on both sides of the medium outlet 31 and the medium outlet 31 can be more uniform, so that the heat exchange medium can flow out of the second manifold 30 faster.

[0071] In summary, the heat exchanger provided by the embodiment of the present application has at least the following beneficial effects:

[0072] In the embodiment of the present application, the heat exchanger includes a plurality of heat exchange assemblies arranged side by side. A heat exchange medium can be introduced into the heat exchange assemblies to realize the circulation of the heat exchange medium, so as to realize the heat exchange function of the heat exchanger. Among them, the heat exchanger is also provided with a regulating valve, and the regulating valve is respectively communicated with a plurality of heat exchange assemblies. By controlling the regulating valve, the flow rate or flow velocity of the heat exchange medium entering the plurality of heat exchange assemblies from the regulating valve can be adjusted. When the flow rate or flow velocity of the heat exchange medium in the plurality of heat exchange assemblies is different, different temperatures can be achieved between different heat exchange assemblies, so as to realize the multi-temperature zone function of the heat exchanger, so as to simultaneously meet the temperature requirements of different users and improve user comfort and user experience.

[0073] The embodiment of the present application also provides a thermal management system, including a medium input pipeline, a medium output pipeline, and the heat exchanger as described above. Among them, the medium input pipeline is connected to the regulating valve 40 to introduce the heat exchange medium into the heat exchange assembly 10 through the regulating valve 40, and the medium output pipeline is connected to the heat exchange assembly 10 to export the heat exchange medium.
