Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a heat exchanger, battery device and electrical equipment. Background Technology

[0002] The battery pack is a core component of electrical equipment, and its performance directly affects the performance of the equipment.

[0003] Currently, cooling of heat-generating components such as battery packs is typically achieved using liquid cooling plates. Specifically, a liquid cooling plate is usually attached to the bottom of the heat-generating component, such as the battery pack. The cooling medium flowing within the liquid cooling plate carries away heat from the battery pack, thus cooling it. However, for battery packs with multiple battery cells, there are gaps between them for structural components. Using a liquid cooling plate would interfere with these structural components, requiring the components to be moved outside the gaps, thus reducing the space utilization of the battery pack.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0059] With the development of new energy sources, more and more fields are adopting new energy sources as power sources. Due to their advantages such as high energy density, rechargeability, safety, and environmental friendliness, batteries are widely used in new energy vehicles, consumer electronics, energy storage systems, and other fields.

[0060] Power batteries are a core component of new energy vehicles, and their safety directly affects the overall safety performance of the vehicle.

[0061] Currently, cooling of heat-generating components such as battery packs is usually achieved through liquid cooling plates. Specifically, the liquid cooling plate is typically attached to the bottom of the heat-generating component, such as the battery pack. In this way, the cooling medium flowing in the liquid cooling plate can carry away the heat from the battery pack, thereby cooling the battery pack.

[0062] However, for battery packs with multiple battery modules, there are gaps between the modules to accommodate structural components. Using liquid cooling plates can interfere with these structural components, requiring the structural components to be moved outside the gaps, which reduces the space utilization of the battery pack.

[0063] To address the aforementioned problems, embodiments of this application provide a novel heat exchanger, battery device, and electrical equipment. The heat exchanger includes at least a heat exchange element and a flow channel. The heat exchange element includes a heat exchange body and at least one first clearance portion connected to the heat exchange body. The heat exchange body is used for heat exchange with a battery pack, and the first clearance portion is used to be disposed between adjacent battery packs. At least a portion of the flow channel is disposed on the side of the heat exchange body away from the battery pack, and the flow channel is used for circulating a heat exchange medium. The heat exchanger provided by embodiments of this application can improve the space utilization rate of the battery device.

[0064] The following detailed description, in conjunction with the accompanying drawings, describes the heat exchanger, battery device, and electrical equipment provided in the embodiments of this application.

[0065] Figure 1 This is a schematic diagram of a battery device provided in an embodiment of this application. Figure 2 This is another schematic diagram of the battery device provided in the embodiments of this application. Figure 3 This is a schematic diagram of the heat exchanger provided in an embodiment of this application.

[0066] Reference Figures 1 to 3 As shown, this application embodiment provides a heat exchanger 100 for dissipating heat from a battery module 210. The battery module 210 may include multiple battery packs 211. Specifically, the heat exchanger 100 may include at least a heat exchange element 110 and a flow channel 120.

[0067] In some embodiments, one side of the heat exchanger 110 may be in contact with the battery module 210, and the flow channel 120 may be disposed on the other side of the heat exchanger 110.

[0068] In this embodiment of the application, the heat exchanger 110 may include a heat exchange body 111 and at least one first clearance part 112. The first clearance part 112 is connected to the heat exchange body 111. The heat exchange body 111 is used to exchange heat with the battery pack 211, and the first clearance part 112 is used to be disposed between adjacent battery packs 211.

[0069] In this embodiment of the application, a portion of the heat exchange component 110 may be recessed toward the battery pack 211 to form a first clearance portion 112.

[0070] It should be noted that, in this embodiment, the first clearance portion 112 is designed to avoid other structural components between the battery packs 211 in the battery module 210. The heat exchange component 110 needs to be designed to conform to the actual contour of the battery module 210.

[0071] In this embodiment, the size of the heat exchanger 110 and the specific location and number of the first clearance portion 112 can be flexibly designed according to the outline of the battery module 210, and this embodiment does not limit this.

[0072] Exemplarily, in the embodiments of this application, such as Figure 3 As shown, the heat exchanger 110 includes a heat exchange body 111 and two first clearance portions 112. The two first clearance portions 112 are connected to the heat exchange body 111, and the heat exchange body 111 and the two first clearance portions 112 are adapted to the side of the battery module 210 facing the heat exchanger 110. At this time, the heat exchanger 110 presents a "U" shape.

[0073] In this embodiment, at least a portion of the flow channel 120 may be disposed on the side of the heat exchange body 111 away from the battery pack 211, and the flow channel 120 is used to circulate the heat exchange medium.

[0074] It should be noted that, in the embodiments of this application, the flow channel 120 may be provided only on the side of the heat exchange body 111 away from the battery pack 211. The flow channel 120 may extend along the arrangement direction of the heat exchange body 111 and the first clearance part 112, or it may intersect with the arrangement direction of the heat exchange body 111 and the first clearance part 112, or the flow channel 120 may be provided on both the heat exchange body 111 and the first clearance part 112.

[0075] In this embodiment of the application, at least a portion of the flow channel 120 may be disposed in the first clearance portion 112.

[0076] In this embodiment, the flow channel 120 can extend along the arrangement direction of the heat exchange body portion 111 and the first clearance portion 112, and a portion of the flow channel 120 can be recessed toward the battery pack 211 to form a second clearance portion 132, which can be connected to the first clearance portion 112.

[0077] In this embodiment, the cooling medium flows within the flow channel 120 and exchanges heat with the battery pack 211 through the heat exchanger 110, so as to maintain the temperature of the battery pack 211 within a suitable range.

[0078] By designing the heat exchanger 100 to include a heat exchange element 110 and a flow channel 120, the heat exchange body 111 of the heat exchange element 110 is used to exchange heat with the battery pack 211, the first clearance portion 112 of the heat exchange element 110 is used to be disposed between adjacent battery packs 211, and at least a portion of the flow channel 120 is disposed on the side of the heat exchange body 111 away from the battery pack 211, and the flow channel 120 is used to circulate the heat exchange medium. In this way, the first clearance portion of the heat exchange element can avoid structural components, and the heat exchange element can adaptably cool multiple battery packs 211. Therefore, the space utilization of the battery device 200 can be improved while cooling multiple battery packs 211.

[0079] Figure 4 This is a partial structural schematic diagram of a heat exchanger 100 provided in an embodiment of this application. Figure 5 This is a schematic diagram of another partial structure of the heat exchanger 100 provided in an embodiment of this application. Figure 6 This is another partial structural schematic diagram of the heat exchanger 100 provided in an embodiment of this application. Figure 7 This is another partial structural schematic diagram of the heat exchanger 100 provided in an embodiment of this application.

[0080] In this embodiment, the heat exchanger 100 may further include a heat exchange tube 130, the interior of which may form a flow channel 120 (see...). Figure 4 and Figure 5 as shown in Figure 5 , and a cooling medium for refrigeration is provided in the flow channel 120.

[0081] It should be noted that, in the embodiment of the present application, the heat exchange tube 130 can be a hollow single-channel pipe, and the heat exchange tube 130 can be processed by an extrusion method.

[0082] In addition, in a possible implementation manner, the heat exchange tube 130 and the heat exchange member 110 can be connected by a brazing method or an adhesive application method, so as to ensure good contact between the two, and further maintain good heat exchange between the heat exchanger 100 and the battery module 210.

[0083] Continue to refer to Figure 4 and Figure 5 As shown in Figure 5 , in the embodiment of the present application, the heat exchange tube 130 can include a main pipe portion 131 and at least one second avoidance portion 132. Among them, the second avoidance portion 132 is connected to the main pipe portion 131, the main pipe portion 131 can be connected to the heat exchange main body portion 111, and the second avoidance portion 132 can be connected to the first avoidance portion 112.

[0084] Exemplarily, in the embodiment of the present application, as Figure 3 shown in Figure 3 , the heat exchange tube 130 includes a main pipe portion 131 and two second avoidance portions 132. Among them, the two second avoidance portions 132 are connected to the main pipe portion 131, and the two second avoidance portions 132 and the main pipe portion 131 are adapted to the surface of the heat exchange member 110 facing the flow channel 120. At this time, the heat exchange tube 130 presents a "ji" shape, and the entire heat exchanger 100 can be in a "ji" shape.

[0085] In the embodiment of the present application, as Figure 1 and Figure 2 shown in Figure 2 , the heat exchanger 100 can be arranged closely following the contour of the battery module 210, and the structure of the heat exchanger 100 is very compact, occupying very little space.

[0086] The heat exchanger 100 is applicable to the situation of cooling multiple separate battery packs 211 and there are other structural members blocking between the battery packs 211.

[0087] For example, when the space inside the battery pack is narrow and multiple separate battery packs 211 need to be cooled, the heat exchanger 100 in the embodiment of the present application can be used.

[0088] As Figure 1 and Figure 2As shown, the battery module 210 has three layers. The top layer is divided into three battery packs 211. The two adjacent battery packs 211 are blocked by the vehicle frame beam 300. In this case, it is not possible to use a single liquid cooling plate to cool the upper part of the three battery packs 211 at the same time. Therefore, the "U"-shaped heat exchanger 100 in the embodiment of this application is required.

[0089] In this embodiment, the specific structure of the main tube 131 and the second clearance part 132 may include, but is not limited to, the following two possible implementations:

[0090] One possible implementation is as follows: Figure 4 As shown, the main tube 131 and the second clearance portion 132 are integrally formed. When there is sufficient available space, a bent heat exchanger 110 can be used directly. That is, the connection between the main tube 131 and the second clearance portion 132 can be continuously extruded.

[0091] Another possible implementation is: Figure 5 As shown, the main tube section 131 and the second clearance section 132 are two independent components.

[0092] When the main tube section 131 and the second clearance section 132 are two independent components, the heat exchanger 100 may further include a first adapter 140, through which the main tube section 131 and the second clearance section 132 may be connected.

[0093] Because there is a minimum bending angle requirement for pipe bends, the bent heat exchanger tube 130 will interfere with other components. When space is limited and the bending radius is smaller than the minimum bending radius of the heat exchanger 110, the main tube section 131 and the second clearance section 132 can also be connected in sections. That is, at the connection between the main tube section 131 and the second clearance section 132, the first adapter 140 can be connected to the main tube section 131 and the second clearance section 132 respectively.

[0094] In one possible implementation, the first adapter 140 can be connected to the main tube 131 and the second clearance part 132 by brazing.

[0095] In some embodiments, the heat exchanger 100 may further include a flow channel component, which may have a flow channel structure and may be connected to the side of the heat exchanger 110 away from the battery pack 211 to enclose and form a flow channel 120.

[0096] In this embodiment of the application, the heat exchange body 111 and the first clearance part 112 can be arranged along the first direction, and the flow channel 120 can extend along the first direction.

[0097] In this embodiment, the heat exchange tube 130 may be designed in a serpentine pattern.

[0098] In this embodiment, the number of heat exchange tubes 130 can be one, two, three, four, or more. The more heat exchange tubes 130 there are, the better the heat exchanger 100 can dissipate heat from the battery module 210.

[0099] In other words, there can be multiple flow channels 120, and multiple flow channels 120 can be arranged at intervals along the second direction, which can intersect with the first direction.

[0100] In some embodiments, the number of heat exchange tubes 130 can be one, and the heat exchange tube 130 can be disposed on the side of the heat exchanger 110 away from the battery module 210.

[0101] In this embodiment of the application, the heat exchanger 100 may further include a first connector 150 and a second connector 160, wherein the first connector 150 may be connected to one end of the heat exchange tube 130 to allow the cooling medium to enter the heat exchange tube 130. The second connector 160 may be connected to the other end of the heat exchange tube 130 to allow the cooling medium to flow out of the heat exchange tube 130.

[0102] Alternatively, in some other embodiments, there may be multiple heat exchange tubes 130. Multiple heat exchange tubes 130 may be disposed on the side of the heat exchange element 110 away from the battery module 210, and the extension direction of the multiple heat exchange tubes 130 is the same as the extension direction of the heat exchange element 110.

[0103] In this embodiment, the multiple heat exchange tubes 130 may be evenly spaced on the side of the heat exchanger 110 away from the battery module 210.

[0104] In addition, it should be noted that the width of the heat exchange tube 130 is not limited in this embodiment of the application, and can be flexibly set according to the heat dissipation requirements of the actual application scenario.

[0105] It is understandable that, such as Figure 6 and Figure 7 As shown in the embodiments of this application, the heat exchanger 100 may further include a manifold 170, and at least two of the plurality of flow channels 120 may be interconnected through the manifold 170.

[0106] In this embodiment of the application, the number of manifolds 170 can be at least two, and the at least two manifolds 170 can be located at both ends of the flow channel 120 along the first direction. The heat exchanger 100 can also include a first connector 150 and a second connector 160, and the first connector 150 and the second connector 160 can be respectively connected to at least one manifold 170.

[0107] In the embodiments of this application, the first connector 150 can be used for liquid inlet and the second connector 160 can be used for liquid outlet, or the first connector 150 can be used for liquid outlet and the second connector 160 can be used for liquid inlet. The embodiments of this application do not limit this.

[0108] In this embodiment of the application, the heat exchanger 100 may further include a reinforcing section 123, and the reinforcing section 123 is connected between at least two of the plurality of flow channels 120.

[0109] In this embodiment, the heat exchange body 111 and the first clearance part 112 can be arranged along the first direction, and the flow channel 120 can be bent and extended along the first direction.

[0110] In this embodiment, the flow channel 120 can bend and extend along a second direction, which intersects with the first direction.

[0111] In addition, it is understood that in the embodiments of this application, the heat exchanger 110 and the heat exchange tube 130 can be supplied as a whole, and the heat exchanger 100 does not use quick-connect fittings for internal connection. The components are connected by welding, which results in higher connection strength and lower risk of leakage.

[0112] At this time, in the embodiments of this application, such as Figure 6 As shown, the heat exchanger 100 may further include a first connector 150 and a second connector 160, wherein the first connector 150 may be connected to at least one of the plurality of heat exchange tubes 130 to allow cooling medium to enter the heat exchange tube 130. The second connector 160 may be connected to at least one of the plurality of heat exchange tubes 130 to allow cooling medium to flow out of the heat exchange tube 130.

[0113] In some embodiments, the manifold 170 is connected to the heat exchanger 110, and the first connector 150 and the second connector 160 may be welded to the manifold 170 to connect the heat exchanger 110 and the external water pipe, so that the cooling medium can flow into and out of the heat exchanger 100.

[0114] In one possible implementation, the heat exchanger 100 may be provided with a first connector 150 and a second connector 160 at both ends, which are connected to the pipeline outside the battery pack, so that the cooling medium can flow into and out of the heat exchanger.

[0115] It should be noted that the first connector 150 and the second connector 160 can be directly connected to the manifold 170. In this case, the heat exchanger 100 acts as an independent heat exchanger and is not connected to other heat exchangers. Alternatively, the heat exchanger 100 can also be connected to other heat exchangers through the manifold 170, that is, the cooling medium flows from one manifold 170 into another heat exchanger and then flows back from the other manifold 170.

[0116] It should be noted that the specific structure and dimensions of the first connector 150, the second connector 160, and the manifold 170 are not limited in the embodiments of this application, and can be flexibly set according to the needs of the actual application scenario.

[0117] like Figure 1 and Figure 2 As shown in the illustration, this application also provides a battery device 200, which may include a plurality of battery packs 211 and the heat exchanger 100 described above. At least two battery packs 211 may have a gap between them, and a first clearance portion 112 may be disposed within the gap.

[0118] By providing the heat exchanger 100 in the battery device 200, the heat dissipation capacity of the battery module 210 in the battery device 200 can be improved, thereby enhancing the performance of the battery device 200.

[0119] It should be noted that, in the embodiments of this application, the heat exchange body 111 and the first clearance part 112 can be arranged along the first direction, and the battery pack 211 can include: a plurality of batteries, wherein the plurality of batteries can be electrically connected sequentially along the first direction L1 to form the battery pack 211, and the extension direction of the flow channel 120 in the heat exchanger 100 can be parallel to the first direction L1.

[0120] In this way, the extension direction of the heat exchange tube 130 is parallel to the arrangement direction of the multiple batteries in the battery pack 211, and the heat exchange tube 130 can cool each battery in the battery pack 211, thereby improving the heat dissipation uniformity when the heat exchanger 100 dissipates heat from the battery module 210.

[0121] In this embodiment of the application, some of the battery packs 211 in the plurality of battery packs 211 can be stacked along the height direction of the battery device 200. There is a gap between two adjacent battery packs 211 in the plurality of battery packs 211 located at the top layer of the battery device 200, and a plurality of first clearance parts 112 can be respectively arranged in the gap.

[0122] In this embodiment of the application, the battery device may further include: a tray and a sealing cover, wherein the tray and the sealing cover enclose a receiving cavity, the battery pack 211 and the heat exchanger 100 may be disposed in the receiving cavity, and the sealing cover has a third clearance portion, which may be correspondingly disposed with the first clearance portion 112.

[0123] In addition, this application embodiment also provides an electrical device, which may include at least: an electrical device body and the aforementioned battery device 200, wherein the battery device 200 can be used to supply power to the electrical device body.

[0124] It should be noted that the electrical equipment of this utility model can be conventional electrical equipment in the field, such as power equipment (e.g., electric vehicles), electronic equipment (e.g., computers, mobile phones, digital cameras, printers, fax machines, etc.), wearable devices (e.g., watches, bracelets, VR glasses, etc.), and home appliances (e.g., air conditioners, refrigerators, washing machines, microwave ovens, etc.), etc., and there are no special limitations in this regard.

[0125] In this embodiment, the electrical equipment can be a vehicle. Taking a vehicle as an example, the vehicle can be a sedan, bus, or truck. For instance, the vehicle can be an electric vehicle (EV), a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), a new energy vehicle, or any vehicle with a battery.

[0126] The vehicle may also include a body, axles, and a motor, wherein the battery pack, axles, and motor may all be mounted on the body. The battery pack may be electrically connected to the motor, and the motor may be connected to the axle. The battery pack provides power to the motor, enabling it to rotate. During rotation, the motor drives the axle to rotate, thus allowing the vehicle to move.
