Description

Technical Field

[0001] This application relates to the field of battery technology, and more particularly to battery devices and power-consuming devices. Background Technology

[0002] New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already widely used. In addition, batteries are being used more and more in the field of energy storage.

[0003] In battery-powered new energy vehicles, batteries can provide all or part of the power. In the energy storage field, batteries can be installed in energy storage enclosures or directly on the user side. In these application scenarios, battery devices are equipped with adapter components for connecting to external heat exchange pipelines. During installation and use, the interfaces of these adapter components are often singular and have a fixed orientation, making it difficult to meet the connection requirements of diverse interfaces. Therefore, improving the multi-directional adaptability of adapter components is one of the research topics in the industry. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a battery device and an electrical device.

[0005] This application is achieved through the following technical solution.

[0006] A first aspect of this application provides a battery device. In some embodiments, the battery device includes a housing, a plurality of battery cells, a heat exchanger, and a transfer assembly. The housing has a receiving space, and the heat exchanger is used for heat exchange with the battery cells. Along a first direction, a portion of the heat exchanger protrudes from the receiving space, the first direction being perpendicular to the direction of gravity. The heat exchanger has a flow channel for receiving a heat exchange medium. The transfer assembly is disposed on the protruding portion of the heat exchanger and located outside the receiving space. The transfer assembly has a plurality of transfer interfaces and a plurality of surfaces. At least two of the transfer interfaces are opened on different surfaces of the transfer assembly, and the transfer interfaces are used to connect the flow channel to an external pipeline.

[0007] In the technical solution of this application embodiment, since the heat exchanger protrudes from the housing space along the first direction, and the adapter is disposed on the protruding part of the heat exchanger and located outside the housing space, the installation of the adapter does not require occupying the space inside the housing for accommodating battery cells. This avoids pipes and connectors encroaching on the arrangement space of battery cells, improves the energy density of the battery device, and simplifies the internal structure. In addition, since the adapter has multiple adapter interfaces on different surfaces, it can be used to achieve branch connections with multiple external pipes through the access point of a single heat exchanger. The number of interfaces meets the requirements of diverse interfaces and simplifies the layout of the external thermal management pipes of the battery device.

[0008] In some embodiments, the adapter assembly includes an adapter connector and an adapter tube, the adapter tube connecting the adapter connector and the flow channel, and the adapter connector having a plurality of the adapter interfaces.

[0009] In the technical solution of this application embodiment, the adapter component adopts a modular design, which facilitates processing and assembly. In addition, since the adapter has multiple interfaces, the position of the adapter can be adapted to the installation requirements of external pipelines in different locations and directions, and it is convenient to centrally connect and manage multiple external pipelines, further simplifying the layout of external thermal management pipelines.

[0010] In some embodiments, the adapter has the adapter interface on at least one side along the direction of gravity, and / or the adapter has a plurality of the adapter interfaces along the direction perpendicular to the direction of gravity.

[0011] In the technical solution of this application embodiment, the multi-directional arrangement of the adapter interface is realized, which improves the versatility and flexible adaptability of the adapter component. It eliminates the need to redesign the adapter according to the direction of different external pipelines, meets the connection requirements of external thermal management pipelines, avoids mutual interference between thermal management pipelines, and optimizes the installation layout of the battery device.

[0012] In some embodiments, the battery device includes a first adapter component and a second adapter component, the first adapter component being connected to the liquid inlet of the flow channel and the second adapter component being connected to the liquid outlet of the flow channel.

[0013] In the technical solution of this application embodiment, the inlet flow path and the outlet flow path are completely separated, thus avoiding mutual interference between the inlet and outlet pipelines.

[0014] In some embodiments, the first adapter assembly includes a first adapter connector and a first adapter tube, the first adapter tube communicating with the flow channel and the first adapter connector, and the first adapter connector having a plurality of first adapter interfaces; the second adapter assembly includes a second adapter connector and a second adapter tube, the second adapter tube communicating with the flow channel and the second adapter connector, and the second adapter connector having a plurality of second adapter interfaces; the first adapter connector and the second adapter connector are plugged in, bolted together, or integrally formed.

[0015] In the technical solution of this application embodiment, since the first adapter and the second adapter are integrally formed, the number of independent parts is reduced, the structure of the adapter assembly is simplified, and the ability of the adapter assembly to resist external vibration and impact is enhanced, reducing the risk of heat exchange medium leakage due to seal failure and improving stability.

[0016] In some embodiments, the adapter assembly includes a sealing element, wherein the first adapter and / or the second adapter have an opening on the side away from the heat exchanger along the direction of gravity, and the sealing element covers the opening.

[0017] In the technical solution of this application embodiment, since the sealing component can be detachably covered and the gravity direction is away from the opening of the heat exchange component, the sealing component forms a sealing barrier to prevent the internal structure of the adapter from being exposed to the outside, effectively blocking external dust, water vapor and other impurities from entering the interior of the adapter, avoiding the flow channel from being blocked, and at the same time preventing the heat exchange medium from leaking and contaminating the components around the battery device, thereby improving the stability of the battery device.

[0018] In some embodiments, the first adapter is detachably connected to one side of the housing along the first direction, the second adapter is detachably connected to one side of the housing along the first direction, and / or the adapter assembly includes a mounting base, the first adapter pipe is detachably connected to the heat exchanger, and the second adapter pipe is detachably connected to the heat exchanger.

[0019] In the technical solution of this application embodiment, since the first adapter, the second adapter and the housing are detachably connected to one side along the first direction, when the adapter needs to be repaired or replaced, the adapter can be quickly disassembled without replacing the entire adapter assembly, which shortens the maintenance time and improves the convenience and efficiency of maintenance.

[0020] In some embodiments, the battery device includes a protective assembly comprising a protective shield detachably connected to the housing, and at least a portion of the adapter assembly is disposed between the protective shield and the housing.

[0021] In the technical solution of this application embodiment, since the protective component includes a protective cover, and at least a portion of the adapter component is disposed between the protective cover and the housing, the protective cover can provide a certain degree of physical protection for the adapter component. This reduces the impact, collision, and scratches caused by external vibrations and shocks, protecting the structural integrity of the adapter component and preventing heat exchange medium leakage due to damage to the adapter component, thereby improving the stability and reliability of the battery device. Furthermore, the removable protective cover facilitates the inspection, replacement, and maintenance of the adapter component, improving maintenance efficiency.

[0022] In some embodiments, the protective component includes an insulation layer that covers at least a portion of the adapter component.

[0023] In the technical solution of this application embodiment, since the insulation layer wraps at least part of the transfer component, it can reduce the heat exchange between the heat exchange medium in the transfer component and the external environment to a certain extent, maintain the temperature stability of the heat exchange medium during the flow process, and improve the heat exchange efficiency of the heat exchange component.

[0024] In some embodiments, at least two of the adapter interfaces intersect in the channel extension direction within the adapter assembly.

[0025] In the technical solution of this application embodiment, the adapter component can be flexibly connected to external pipelines in various directions through the adapter interface, thereby improving the adaptability of the adapter component.

[0026] The second part of the embodiments of this application discloses an electrical device, which in some embodiments includes the battery device described in the first part of the embodiments of this application, the battery device being used to store or provide electrical energy.

[0027] In the technical solution of this application embodiment, the layout of the internal thermal management pipeline of the electrical device can be simplified, and the assembly difficulty of the adapter components and pipelines can be reduced.

[0028] In some embodiments, the electrical device is a vehicle, and the multiple adapter ports of the adapter assembly are connected to the vehicle's water pump and air conditioner via the external piping.

[0029] In the technical solution of this application embodiment, the multiple adapter interfaces can be connected to pipelines in multiple areas of the vehicle, such as the engine compartment, chassis, and body, to meet the requirements of interface direction and space constraints in different areas.

[0030] The beneficial effects of the embodiments disclosed herein include: through this application, it is possible to use the adapter component to achieve a split connection with multiple external pipelines through the access point of a single heat exchanger, the number of interfaces meets the diverse interface requirements, and simplifies the layout of the external thermal management pipelines of the battery device.

[0031] The above description is only an overview of the technical solution of this application.

[0053] The following is a detailed description of this application.

[0054] Currently, new energy batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0055] In battery-powered new energy vehicles, batteries can provide all or part of the power. In the field of energy storage, batteries can be installed in energy storage enclosures or directly on the user side. In these application scenarios, the heat exchange adapter components of the battery device often have a single interface and a fixed orientation, making it difficult to meet the connection requirements of diverse interfaces. Therefore, improving the multi-directional adaptability of adapter components is one of the research topics in the industry.

[0056] After research and design, a transfer assembly is installed outside the battery device casing. The transfer assembly connects the inlet and outlet of the heat exchange component and has multiple adapters, each of which connects to the external heat exchange pipeline.

[0057] Based on this design concept, this application provides a battery device, which includes a housing, multiple battery cells, a heat exchanger, and a connecting assembly. The housing has a receiving space, and along a first direction, a portion of the heat exchanger protrudes from the receiving space. The first direction is perpendicular to the direction of gravity. The heat exchanger has a flow channel for receiving a heat exchange medium. The connecting assembly is disposed on the protruding portion of the heat exchanger and located outside the receiving space. The connecting assembly has multiple connecting interfaces and multiple surfaces. At least two connecting interfaces are opened on different surfaces of the connecting assembly. The connecting interfaces are used to connect the flow channel and an external pipeline.

[0058] In the technical solution of this application embodiment, since the heat exchanger protrudes partially from the housing space along the first direction, and the adapter is disposed on the protruding part of the heat exchanger and located outside the housing space, the installation of the adapter does not require occupying the space inside the housing for accommodating battery cells. This avoids pipes and connectors encroaching on the arrangement space of battery cells, improves the energy density of the battery device, and simplifies the internal structure. In addition, since the adapter has multiple adapter interfaces disposed on different surfaces, it can be used to achieve branch connections with multiple external pipes through the access point of a single heat exchanger. The number of interfaces meets the requirements of diverse interfaces, simplifying the layout of the external thermal management pipes of the battery device.

[0059] In the following embodiments, for ease of explanation, a vehicle 1000 is used as an example of an electrical device according to an embodiment of this application. The description is as follows with reference to the accompanying drawings.

[0060] Figure 1 The diagram illustrates the structure of a vehicle 1000 as provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. Figure 1 As shown, a battery device 100 is installed inside the vehicle 1000. The battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0061] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0062] Figure 2 This is an exploded perspective view of the battery device 100 provided in an embodiment of this application. Figure 2 As shown, the battery device 100 includes a base plate 103, a cover 102, and at least one battery cell 104. The cover 102 covers the base plate 103, thereby forming a space for receiving the battery cell 104.

[0063] In the embodiments of this application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0066] The battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.

[0067] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells; as an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form a single module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0068] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0069] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0070] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0071] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0072] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0073] As an example, the housing can be part of the vehicle's chassis structure. For instance, the housing's roof can be at least part of the vehicle's floor, or the housing's frame can be at least part of the vehicle's crossbeams and longitudinal beams.

[0076] Below, refer to Figures 3 to 9 Some embodiments of this application will be described in detail.

[0077] Figure 3 Schematic diagrams of the battery device provided for some embodiments of this application; Figure 4 for Figure 3 Schematic diagram of the structure at point A; Figure 5 for Figure 3 Assembly diagram at point A; Figure 6 Schematic diagrams of the battery device provided for some embodiments of this application; Figure 7 for Figure 6 Sectional view at point BB; Figure 8 for Figure 6 Sectional view at CC; Figure 9 This is a schematic diagram of the structure of an adapter component provided for some embodiments of this application.

[0078] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a gravity direction are defined. These directions intersect each other, including perpendicular intersections. To facilitate understanding of the embodiments of this application, the embodiments shown in Figures 3 to 9 are illustrated using the example of the first direction, second direction, and gravity direction being perpendicular intersections. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect perpendicularly. For ease of explanation, as indicated by the arrows in Figures 2 to 9, the direction of arrow X is considered the first direction, the direction of arrow Y is considered the second direction, and the direction of arrow Z is considered the gravity direction. Sometimes, the direction pointed to by arrow Z along the gravity direction is referred to as "above," and its opposite direction as "below."

[0079] A first aspect of this application provides a battery device 100. In an embodiment of this application, the battery device 100 includes a housing 101, a plurality of battery cells 104, a heat exchanger 1, and a transfer assembly. The housing 101 has a receiving space, and the heat exchanger 1 is used for heat exchange with the battery cells 104. Along a first direction (X), a portion of the heat exchanger 1 protrudes from the receiving space. The first direction (X) is perpendicular to the direction of gravity (Z). The heat exchanger 1 has a flow channel 2 for receiving a heat exchange medium. The transfer assembly is disposed on the protruding portion of the heat exchanger 1 and located outside the receiving space. The transfer assembly has a plurality of transfer interfaces and a plurality of surfaces. At least two transfer interfaces are opened on different surfaces of the transfer assembly. The transfer interfaces are used to connect the flow channel 2 to an external pipeline.

[0080] Optionally, the housing 101 can adopt various structures. For example, such as... Figure 2 As shown, the box 101 can be a hollow structure with one side open, and the cover 102 closes to the open side, thus forming a box 101 with a placement space. Alternatively, the box 101 can also be constructed as a closed box 101.

[0081] For example, such as Figure 3 As shown, the box 101 may include a frame, and the area inside the frame is a receiving space.

[0082] Optionally, the housing 101 may also include a cover 102, which is disposed on both sides of the frame with the heat exchanger 1. The heat exchanger 1 and the cover 102 together with the frame define the accommodating space.

[0083] Understandably, the frame material should possess sufficient strength, rigidity, and corrosion resistance to provide support and protection within the battery device 100 while minimizing weight to improve energy efficiency. Commonly used materials include aluminum alloys, high-strength steel, or composite materials.

[0084] Alternatively, the frame can be made of a metal material with a certain strength.

[0085] Alternatively, the frame can be formed by die casting, roll forming, extrusion forming, or cutting from profiles.

[0086] Optionally, the shape of the border may include, but is not limited to, a rectangular structure, a circular structure, a triangular structure, a pentagonal structure, a hexagonal structure, a rhombus structure, or an elliptical structure. Accordingly, the shape of the accommodating space matches the shape of the border.

[0087] It is understandable that the heat exchanger 1 can be a water-cooled plate, which can contact the battery cell 104 and achieve heat exchange with the battery cell 104.

[0088] Optionally, the heat exchanger 1 can be in direct contact with the battery cell 104, or indirect contact can be achieved through a thermally conductive layer, adhesive layer, or other means.

[0089] Optionally, the heat exchanger 1 can cool or heat the battery cell 104 to maintain the operating temperature of the battery cell 104.

[0090] Optionally, the heat exchanger 1 can be made of a metal with excellent thermal conductivity, such as aluminum alloy or copper alloy.

[0091] Optionally, the heat exchanger 1 can be disposed on one side of the housing 101 along the gravity direction (Z), or on one side of the housing 101 along the first direction (X), or on one side of the housing 101 along the second direction (Y).

[0092] For example, the heat exchanger 1 is disposed at the bottom of the housing 101 and can serve as a base plate 103 to support the battery cell 104.

[0093] For example, such as Figure 3 , Figure 4 , Figure 5 As shown, heat exchanger 1 protrudes from the housing space and the box 101, and flow channel 2 also extends to the outside of the box 101.

[0094] It is understood that the embodiments of this application do not limit the shape and size of the protruding part, and can be designed according to the specific installation environment.

[0095] For example, such as Figure 3 , Figure 4 , Figure 6 As shown, the adapter assembly is also located on the outside of the housing 101.

[0096] Optionally, the heat exchanger 1 may include two stacked heat exchanger 1s, with a flow channel 2 defined between the two heat exchanger 1s.

[0097] It is understandable that the flow channel 2 is a channel opened inside the heat exchanger 1 to contain the heat exchange medium, realize the circulation of the heat exchange medium, and then exchange heat with the battery cell 104.

[0098] Optionally, the cross-sectional shape of the flow channel 2 can be circular, elliptical, square, rectangular or other irregular shapes, and this embodiment does not limit this.

[0099] It is understood that the flow channel 2 can be a straight shape, a bent shape, or a combination of both. This application does not limit the shape of the flow channel 2 in its embodiments.

[0100] Understandably, the number and shape of the flow channels 2 can be adjusted according to the size of the heat exchange component 1 and the heat dissipation requirements of the battery cell 104. Multiple flow channels 2 connected in parallel can improve heat exchange uniformity.

[0101] It is understandable that the heat exchange medium is a medium that circulates and transfers heat between the flow channel 2 and the external pipeline, which can carry away the heat generated by the battery cell 104 when it is working, or provide heat to the battery cell 104 in a low-temperature environment.

[0102] Optionally, the heat exchange medium may be water, ethylene glycol solution, mineral oil, etc., and the embodiments of this application do not limit this.

[0103] It is understandable that the adapter is an intermediate component that connects the heat exchanger 1 to the external pipeline (not shown), enabling the flow channel 2 to connect with the external pipeline, and can adapt to the connection requirements of external pipelines of different directions and specifications.

[0104] Optionally, the number of adapter components is at least two, with the inlet 2A and outlet 2B of the flow channel 2 each connected to at least one adapter component. Optionally, multiple adapter components can be arranged on the same side of the housing 101, for example, on the same side along the first direction (X), or they can be arranged on different sides.

[0105] Optionally, multiple adapter components can be molded as a single piece, or multiple adapter components can be set up independently.

[0106] Optionally, each adapter component has multiple adapter interfaces. These multiple adapter interfaces may have the same shape and size, or they may have different shapes and sizes. This application embodiment does not limit this.

[0107] Optionally, the adapter interface in each adapter assembly faces a different direction. For example, the adapter interface may be opened on one side of the adapter assembly (specifically the adapter connector) along a first direction (X), a second direction (Y), or the direction of gravity (Z).

[0108] Optionally, the adapter interface can be a threaded interface, a flange interface, a quick-connect interface, etc., and this application embodiment does not limit this.

[0109] It is understandable that the adapter has multiple surfaces along different directions. For example, along the direction of gravity (Z), the adapter has a first surface and a second surface; along the first direction (X), the adapter has a third surface and a fourth surface; and along the second direction (Y), the adapter has a fifth surface and a sixth surface.

[0110] It is understood that multiple adapter interfaces are located on different surfaces of the adapter component. For example, two adapter interfaces may be located on opposite first and second surfaces, or they may be located on adjacent surfaces, such as the first and third surfaces. Other embodiments are not listed here, and this application does not limit the scope of the application.

[0111] For example, multiple adapter interfaces on the same surface can be of equal size.

[0112] As another example, the sizes of multiple adapter interfaces on different surfaces may not be equal.

[0113] For example, the adapter interface may be equipped with seals (such as sealing rings or gaskets) to further improve sealing and prevent leakage of heat exchange medium.

[0114] It is understandable that, although not shown in the diagram, the adapter interface can be connected to an external thermal management pipeline (hereinafter referred to as the external pipeline). The external pipeline is a pipeline that connects the adapter component to external equipment (such as the vehicle's air conditioning or water pump) to realize the circulation of the heat exchange medium and to exchange heat on the battery cell 104.

[0115] Understandably, the material and size of the pipes must match the adapter interface.

[0116] Alternatively, the external piping can be made of rubber tubing, metal tubing, or the like.

[0117] In the technical solution of this application embodiment, since the heat exchanger 1 protrudes from the accommodating space of the housing 101 along the first direction (X), and the adapter is disposed on the protruding part of the heat exchanger 1 and located outside the accommodating space, the installation of the adapter does not require occupying the space inside the housing 101 that accommodates the battery cell 104, thus avoiding the encroachment of pipelines and connectors on the arrangement space of the battery cell 104, improving the energy density of the battery device 100, and simplifying the internal structure. In addition, since the adapter has multiple adapter interfaces, it can be used to achieve branch connections with multiple external pipelines through the access point of a single heat exchanger 1. The number of interfaces meets the requirements of diverse interfaces, simplifying the layout of the external thermal management pipelines of the battery device 100.

[0118] In the embodiments of this application, the adapter component includes an adapter connector and an adapter pipe, the adapter pipe connecting the adapter connector and the flow channel 2, and the adapter connector having multiple adapter interfaces.

[0119] It is understandable that the adapter is used to open the adapter interface to connect with the external pipeline and connect the adapter pipe, so as to realize the connection between the adapter pipe, flow channel 2 and the external pipeline, and at the same time distribute or collect the heat exchange medium.

[0120] Optionally, the adapter can be made of stainless steel, copper alloy, aluminum alloy, etc.

[0121] Optionally, the adapter can be in the shape of a block or a ball, etc. For example, such as... Figure 9 As shown, the adapter is a rectangular block, and the block shape makes it easy to open multiple adapter interfaces in different directions.

[0122] It is understandable that the adapter interface is connected to the fluid channel of the adapter pipe, and thus to the flow channel 2.

[0123] Optionally, the adapter and adapter pipe can be integrally molded. Alternatively, they can be designed as separate structures, assembled during installation using threads, flanges, snap-fits, or other methods.

[0124] As is understood, the adapter pipe is the delivery pipe section that connects the adapter to the two ports of the flow channel. Optionally, it is usually a metal pipe (such as stainless steel or aluminum pipe) or a rubber or nylon pipe.

[0125] Optionally, a sealing element, such as a sealing ring or sealing gasket, can be provided at the connection between the adapter pipe and the inlet 2A and the outlet 2B.

[0126] In the technical solution of this application embodiment, the adapter component adopts a modular design, which facilitates processing and assembly. In addition, since the adapter has multiple interfaces, the position of the adapter can be adapted to the installation requirements of external pipelines in different locations and directions, and it is convenient to centrally connect and manage multiple external pipelines, further simplifying the layout of external thermal management pipelines.

[0127] In the embodiments of this application, the adapter has an adapter interface on at least one side along the gravity direction (Z), and / or, the adapter has multiple adapter interfaces in a direction perpendicular to the gravity direction (Z).

[0128] For example, such as Figure 4 , Figure 5 , Figure 9 As shown, the adapter has an adapter interface on one side (below) along the direction of gravity (Z).

[0129] For example, such as Figure 4 , Figure 5 , Figure 9 As shown, the adapter has an adapter interface on at least one side along the first direction (X).

[0130] For example, such as Figure 4 , Figure 5 , Figure 9 As shown, the adapter has an adapter interface on at least one side along the second direction (Y).

[0131] As an example, in an embodiment not shown, the adapter also has an adapter interface on the upper side along the direction of gravity (Z).

[0132] Understandably, multiple adapter ports can be connected to different external pipelines, eliminating the need for external valves, such as three-way valves and four-way valves.

[0133] In the technical solution of this application embodiment, the multi-directional arrangement of the adapter interface is realized, which improves the versatility and flexible adaptability of the adapter component. It eliminates the need to redesign the adapter according to the direction of different external pipelines, meets the connection requirements of external thermal management pipelines, avoids mutual interference between thermal management pipelines, and optimizes the installation layout of the battery device 100.

[0134] In the embodiments of this application, the battery device 100 includes a first adapter component 10 and a second adapter component 20. The first adapter component 10 is connected to the liquid inlet 2A of the flow channel 2, and the second adapter component 20 is connected to the liquid outlet 2B of the flow channel 2.

[0135] For example, the first adapter assembly 10 and the second adapter assembly 20 are disposed on the same side of the housing 101.

[0136] Optionally, the first adapter component 10 may have the same structure as the second adapter component 20, or it may have a different structure.

[0137] Understandably, the heat exchange medium flows into the inlet 2A from the first transfer assembly 10, and after flowing through the flow channel 2 that contacts the battery cell 104, it flows out from the outlet 2B and the transfer interface of the second transfer assembly 20.

[0138] In the technical solution of this application embodiment, the inlet flow path and the outlet flow path are completely separated, thus avoiding mutual interference between the inlet and outlet pipelines.

[0139] In the embodiments of this application, the first adapter assembly 10 includes a first adapter connector 11 and a first adapter pipe 12, the first adapter pipe 12 connects the flow channel 2 and the first adapter connector 11, and the first adapter connector 11 has a plurality of first adapter interfaces 11A; the second adapter assembly 20 includes a second adapter connector 21 and a second adapter pipe 22, the second adapter pipe 22 connects the flow channel 2 and the second adapter connector 21, and the second adapter connector 21 has a plurality of second adapter interfaces 21A; the first adapter connector 11 and the second adapter connector 21 are plugged in, bolted together, or integrally formed.

[0140] Optionally, multiple adapter components can be molded as a single unit.

[0141] For example, the first adapter 11 and the second adapter 21 have different functions. The first adapter 11 is used to connect the external liquid inlet pipe to the first adapter pipe 12, and the second adapter 21 is used to connect the external liquid outlet pipe to the second adapter pipe 22.

[0142] Optionally, the first adapter interface 11A of the first adapter 11 can be adapted to an external liquid inlet pipe (such as an air conditioner liquid outlet pipe or a water pump liquid outlet pipe), and the second adapter interface 21A of the second adapter 21 can be adapted to an external liquid outlet pipe (such as an air conditioner liquid inlet pipe or a water pump liquid inlet pipe). The specifications of the two can be adjusted according to the corresponding pipe to ensure compatibility.

[0143] Optionally, the first adapter 11 and the second adapter 21 are detachably connected. For example, they can be fixed by means of plug-in or bolt connection.

[0144] For example, such as Figure 9 As shown, the two adapters are integrally molded into a block structure, separated by partitions and blocks to prevent the heat exchange medium from mixing between the inlet and outlet liquids.

[0145] Understandably, the first adapter pipe 12 is used to connect the first adapter joint 11 to the liquid inlet 2A of the heat exchanger 1, and the second adapter pipe 22 is used to connect the second adapter joint 21 to the liquid outlet 2B of the heat exchanger 1.

[0146] Optionally, the first adapter pipe 12 and the second adapter pipe 22 can be symmetrically arranged on both sides of the integrally formed adapter joint to form a U-shaped structure, which can be adapted to the position of the liquid inlet 2A and the liquid outlet 2B of the heat exchanger 1, while reducing the space occupied by the pipeline.

[0147] Optionally, the length and diameter of the first adapter pipe 12 and the second adapter pipe 22 may be the same or different, and this application embodiment does not limit this.

[0148] Understandably, the first adapter port 11A is used to connect to the external liquid inlet pipe, allowing the heat exchange medium to enter the first adapter assembly 10, and the second adapter port 21A is used to connect to the external liquid outlet pipe, allowing the heat exchange medium to flow out of the second adapter assembly 20.

[0149] Optionally, the number and orientation of the first adapter 11A and the second adapter 21A can be adjusted according to the external pipeline requirements. For example, the first adapter 11 can have two first adapters 11A in the horizontal direction (for example, to connect the inlet pipelines of the air conditioner and the water pump respectively), and the second adapter 21 can have one second adapter 21A in the vertical direction (to connect the outlet pipeline), thus improving compatibility.

[0150] For example, such as Figure 9 As shown, the first adapter 11 has two first adapter interfaces 11A, and the second adapter interface 21A has two second adapter interfaces 21A.

[0151] Alternatively, the one-piece molding process may include casting, injection molding, machining, stamping, etc.

[0152] Optionally, reinforcing ribs can be installed at the connection between the adapter and the adapter pipe to improve the overall strength and prevent the adapter from deforming or breaking due to external vibration and impact.

[0153] In the technical solution of this application embodiment, since the first adapter 11 and the second adapter 21 are integrally formed, the number of independent parts is reduced, the structure of the adapter assembly is simplified, and the ability of the adapter assembly to resist external vibration and impact is enhanced, reducing the risk of heat exchange medium leakage due to seal failure and improving stability.

[0154] In an embodiment of this application, the adapter assembly includes a sealing member 13, and the first adapter 11 and / or the second adapter 21 have an opening on the side away from the heat exchanger 1 along the direction of gravity (Z), and the sealing member 13 covers the opening.

[0155] Understandably, the sealing component 13 is used to cover and seal the opening to prevent heat exchange medium leakage, and at the same time prevent external dust, water vapor and other impurities from entering the adapter and damaging the internal structure or blocking the flow channel 2.

[0156] Optionally, the material of the sealing component 13 can be the same as that of the adapter (such as stainless steel, copper alloy, aluminum alloy), or it can be a polymer material (such as engineering plastics).

[0157] Optionally, the sealing element 13 can be a block, spherical, or sheet-like structure.

[0158] Optionally, the sealing element is a sheet-like structure, and its shape can be circular, elliptical, square, etc., to match the shape of the opening. Understandably, the thickness of the sealing element 13 can be adjusted according to the sealing pressure; the higher the pressure, the thicker the element, resulting in a more secure seal.

[0159] The opening is located on the side of the first adapter 11 and / or the second adapter 21 away from the heat exchanger 1 along the direction of gravity (Z), that is, at the top of the adapter. The opening facilitates the processing, cleaning and maintenance of the internal flow channels of the adapter.

[0160] Optionally, the specifications of the opening can be adjusted according to the size of the adapter and the structure of the internal flow channel. A sealing groove can be provided on the edge of the opening for installing a seal (such as a sealing ring) to improve the sealing performance of the sealing component 13.

[0161] Optionally, the number of openings can correspond to the number of adapters. The first adapter 11 and the second adapter 21 can each be provided with one opening, or they can share one opening, separated by a partition to avoid crossflow.

[0162] Optionally, the sealing element 13 can be connected to the adapter by means of bonding, welding, snap-fit, threading, etc. The two can be detachable or fixed.

[0163] For example, such as Figure 7 , Figure 8 As shown, the sealing element 13 can be a sealing plate with an opening in a stepped shape, and the sealing plate covers the opening.

[0164] In the technical solution of this application embodiment, since the sealing member 13 can be detachably covered and the gravity direction (Z) is far away from the opening of the heat exchange member 1, the sealing member 13 forms a sealing barrier to prevent the internal structure of the adapter from being exposed to the outside, effectively blocking external dust, water vapor and other impurities from entering the interior of the adapter, avoiding the flow channel 2 from being blocked, and at the same time preventing the heat exchange medium from leaking and contaminating the components around the battery device 100, thereby improving the stability of the battery device 100.

[0165] In the embodiments of this application, the first adapter 11 is detachably connected to the housing 101 along one side of the first direction (X), the second adapter 21 is detachably connected to the housing 101 along one side of the first direction (X), and / or, the adapter assembly includes a mounting base 40, the first adapter pipe 12 is detachably connected to the heat exchanger 1, and the second adapter pipe 22 is detachably connected to the heat exchanger 1.

[0166] Understandably, the mounting base 40 is an auxiliary fixing component of the adapter assembly. It is fitted around the outer periphery of the adapter pipe to fix the adapter pipe, realize the detachable connection between the adapter pipe and the heat exchanger 1, and improve the installation stability and maintenance convenience of the adapter assembly.

[0167] For example, such as Figure 5 As shown, the mounting base 40 may have a flange structure and be connected to the heat exchanger 1 by bolts.

[0168] As another example, the first adapter 11 and the second adapter 21 are fixed to the housing 101 by bolts.

[0169] For example, the adapter is fixed to the enclosure using M5 bolts. This bolt fixing method eliminates the need for welding or riveting, reducing assembly difficulty. During maintenance, only the bolts need to be removed to replace the interface; there is no need to replace the entire enclosure 101.

[0170] Stability: The strength of the M5 bolts is sufficient to ensure the reliability of the interface under vibration.

[0171] In the technical solution of this application embodiment, since the first adapter 11, the second adapter 21 and the housing 101 are detachably connected to one side along the first direction (X), when the adapter needs to be repaired or replaced, the adapter can be quickly disassembled without replacing the entire adapter assembly, which shortens the maintenance time and improves the convenience and efficiency of maintenance.

[0172] In an embodiment of this application, the battery device 100 includes a protective component 30, the protective component 30 includes a protective cover 31, the protective cover 31 is detachably connected to the housing 101, and at least a portion of the adapter component is disposed between the protective cover 31 and the housing 101.

[0173] For example, the protective component 30 is an auxiliary component used to protect the adapter component from bumps, impacts, and foreign object corrosion.

[0174] Optionally, the protective component 30 may include a protective cover 31, which provides physical protection for the adapter to prevent it from being bumped, scratched, or corroded by foreign objects, while also engaging with the housing 101.

[0175] Optionally, the protective cover 31 forms a storage space to store all or part of the adapter components.

[0176] For example, the protective cover 31 houses at least a portion of the transfer pipe.

[0177] Optionally, the protective cover 31 may be made of metal (such as aluminum alloy) or polymer (such as engineering plastic).

[0178] For example, the protective cover 31 is made of lightweight metal stamping sheet, which covers the outside of the adapter pipe to effectively prevent mechanical damage.

[0179] Optionally, a buffer layer (such as a rubber pad or foam pad) can be provided inside the protective cover 31 to reduce the impact of collisions on the adapter components.

[0180] It is understood that the shape and size of the protective cover 31 can be adjusted according to the size of the adapter component and the installation position, for example, to adapt to the shape and size of the adapter pipe. This application embodiment does not limit this.

[0181] For example, such as Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the protective cover 31 can protect the adapter pipe and is detachably connected to the housing 101 by bolts.

[0182] In the technical solution of this application embodiment, since the protective component 30 includes a protective cover 31, and at least a portion of the adapter component is disposed between the protective cover 31 and the housing 101, the protective cover 31 can provide a certain degree of physical protection for the adapter component. This reduces the impact, collision, and scratches caused by external vibrations and shocks, protecting the structural integrity of the adapter component and preventing heat exchange medium leakage due to damage to the adapter component, thereby improving the stability and reliability of the battery device 100. In addition, the detachable protective cover 31 facilitates the inspection, replacement, and maintenance of the adapter component, improving maintenance efficiency.

[0183] In embodiments of this application, the protective component 30 includes an insulation layer 32 that covers at least a portion of the adapter component.

[0184] Understandably, the insulation layer 32 can reduce the heat exchange between the heat exchange medium inside the transfer component and the external environment, maintain the temperature stability of the heat exchange medium, and also has a certain buffering function.

[0185] For example, the insulation layer 32 is an insulation cotton layer, which can be made of glass wool, rock wool, polyurethane foam, silicone wool, etc. The specific material and thickness of the insulation layer 32 are not limited.

[0186] In the technical solution of this application embodiment, since the insulation layer 32 covers at least a portion of the transfer component, it can reduce heat exchange between the heat exchange medium inside the transfer component and the external environment to a certain extent, maintain the temperature stability of the heat exchange medium during the flow process, and improve the heat exchange efficiency of the heat exchanger 1. The dual protection design of the insulation layer 32 and the protective cover 31 significantly improves the durability and reliability of the transfer component and reduces failures caused by external factors.

[0187] In embodiments of this application, at least two adapter interfaces intersect in the channel extension direction within the adapter component.

[0188] It should be noted that the channel inside the adapter assembly refers to the fluid channel inside the adapter assembly. In this embodiment, the fluid channel refers to the part near the adapter. Since multiple adapters can be set on different surfaces, their extension directions intersect.

[0189] Alternatively, the direction of the channel extension can be an acute angle, a right angle, or an obtuse angle.

[0190] For example, such as Figure 7 , Figure 9 As shown, the channel extension directions of multiple adapter interfaces can be perpendicular to each other.

[0191] In the technical solution of this application embodiment, the adapter component can be flexibly connected to external pipelines in various directions through the adapter interface, thereby improving the adaptability of the adapter component.

[0192] The second part of the embodiments of this application discloses an electrical device, which includes the battery device 100 of the first part of the embodiments of this application. The battery device 100 is used to store or provide electrical energy.

[0193] In the technical solution of this application embodiment, the layout of the internal thermal management pipeline of the electrical device can be simplified, and the assembly difficulty of the adapter components and pipelines can be reduced.

[0194] In the embodiments of this application, the electrical device is a vehicle 1000, and the multiple adapter interfaces of the adapter assembly are connected to the water pump and air conditioner of the vehicle 1000 through external pipelines.

[0195] For example, such as Figure 1 As shown, a battery device 100 is installed inside the vehicle 1000. The battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power requirements of the vehicle 1000 during starting, navigation, and driving.

[0196] It is understood that a water pump refers to a mechanical pump that drives the heat exchange medium to circulate between the battery unit 100 and the radiator / heater. Air conditioning refers to the vehicle's cooling system. Through pipe connections, the low-temperature refrigerant in the air conditioning system, as a heat exchange medium, can be introduced into the flow channel 2 of the heat exchanger 1 to cool the battery cells 104.

[0197] Understandably, the air conditioning system of Vehicle 1000 needs to connect to multiple areas of the vehicle, such as the engine compartment, chassis, and body, and the interface directions and space constraints of different areas vary. The fixed refrigerant interface in related technologies cannot meet this multi-directional requirement, resulting in assembly difficulties, complex piping layout, and even affecting the system's sealing and durability.

[0198] In the technical solution of this application embodiment, the multiple adapter interfaces of the adapter component can be connected to pipelines in multiple areas of the vehicle 1000, such as the engine compartment, chassis, and body, to meet the requirements of interface direction and space constraints in different areas. Through the multiple interface design, the arrangement of external pipelines in areas such as the engine compartment and chassis is more flexible, shortening assembly time and significantly improving maintenance efficiency.

[0199] The specific solutions of the embodiments of this application are described below with reference to the accompanying drawings.

[0200] In a specific embodiment, the battery device 100 includes a housing 101 and battery cells 104 inside the housing 101. A water-cooled plate (heat exchanger 1) is provided at the bottom of the housing 101. The heat exchanger 1 protrudes from the housing 101. A transfer assembly is provided on the heat exchanger 1 outside the housing 101, connecting the flow channel 2 of the heat exchanger 1 to an external thermal management pipe. The first transfer assembly 10 and the second transfer assembly 20 are respectively connected to the liquid inlet 2A and the liquid outlet 2B of the flow channel 2.

[0201] In a specific embodiment, the adapter assembly includes an adapter connector, an adapter pipe, a protective assembly 30, and a mounting base 40. The adapter pipe extends upward along the direction of gravity (Z), with its bottom inserted into the heat exchanger 1 and communicating with the inlet and outlet of the flow channel 2, and its top connected to the adapter connector.

[0202] In a specific embodiment, the adapter and the adapter pipe are integrally formed, and the adapter has multiple adapter interfaces, which are connected to components such as air conditioners and water pumps through pipes.

[0203] In a specific embodiment, such as Figure 3 , Figure 4 , Figure 6 As shown, a first adapter assembly 10 and a second adapter assembly 20 are provided on the heat exchanger 1. The two adapter assemblies are integrally formed. Specifically, the first adapter 11 and the second adapter 21 are integrally formed, and the flow channels of the two are separated by a partition.

[0204] In a specific embodiment, the mounting base 40 is fitted around the outer periphery of the adapter pipe, and the mounting base 40 is connected to the heat exchanger 1 by screws. The adapter can also be connected to the housing 101 by screws.

[0205] In a specific embodiment, the protective component 30 also includes a protective cover 31 and an insulation layer 32. The protective cover 31 installs the adapter pipe on the outside of the housing 101, and the insulation layer 32, i.e., insulation cotton, is arranged around the outer periphery of the adapter pipe.

[0206] This solution allows adapters to be configured with upward, downward, front, left, or right outlets to meet various interface requirements, adapting to a wider range of interfaces. The design also enables refrigerant adapters to be arranged in multiple directions to meet the overall vehicle interface needs, overcoming the space limitations of traditional solutions.
