Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] Hereinafter, with reference to the accompanying drawings, a heat exchange assembly 10 according to an embodiment of the present invention will be described.

[0062] like Figures 1-10 As shown, the heat exchange component 10 according to an embodiment of the present invention includes: a heat exchange element 3 for circulating a heat exchange medium and a connecting element 4. The heat exchange element 3 includes a first heat exchange region 31 and a second heat exchange region 32 that are spaced apart. The connecting element 4 is used to connect the first heat exchange region 31 and the second heat exchange region 32.

[0063] This allows the first heat exchange zone 31 and the second heat exchange zone 32 to exchange heat with the corresponding components in a targeted manner, which can improve heat exchange efficiency, reduce temperature difference, and improve the design rationality of the battery box 100.

[0064] For example, refer to Figures 1-7 As shown, the heat exchange assembly 10 includes a heat exchange element 3 and a connecting element 4. The heat exchange element 3 is plate-shaped and has a heat exchange channel inside. The heat exchange channel is used to flow the heat exchange medium, and the cooling medium can be any of the following materials: water, mineral oil, etc.

[0065] The heat exchanger 3 includes a first heat exchange region 31 and a second heat exchange region 32 that are separated from each other. Both the first heat exchange region 31 and the second heat exchange region 32 are provided with heat exchange channels. The first heat exchange region 31 and the second heat exchange region 32 are used to exchange heat with different components. For example, the first heat exchange region 31 can be set to exchange heat with the control module 300, and the second heat exchange region 32 can be set to exchange heat with the battery cell module 200.

[0066] Of course, the first heat exchange area 31 and the second heat exchange area 32 can be set to exchange heat with different types of battery cell modules 200, such as lithium battery packs and sodium battery packs, solid-state batteries and lithium battery packs, etc.

[0067] The connecting member 4 is tubular in shape and is connected to the heat exchange member 3. The connecting member 4 is used to connect the heat exchange channels in the first heat exchange region 31 and the second heat exchange region 32, so that the heat exchange medium can flow from one of the first heat exchange region 31 and the second heat exchange region 32 to the other, so that the heat exchange medium can exchange heat with the control module 300 and the battery module 200 respectively.

[0068] It is understandable that by connecting the first heat exchange area 31 and the second heat exchange area 32 through the connecting member 4, the mutual constraints between the first heat exchange area 31 and the second heat exchange area 32 can be avoided, making the arrangement of the heat exchange channels more flexible. This allows the first heat exchange area 31 and the second heat exchange area 32 to exchange heat with corresponding components (such as the cell module 200 and the control module 300) in a targeted manner. For example, arranging denser channels in higher temperature locations helps to improve heat exchange efficiency, reduces the temperature difference of corresponding components, and enables the battery device 1000 to work more stably. It also helps to reduce the design and processing difficulty of the heat exchange component 3 and improves the practicality of the battery box 100.

[0069] According to the embodiment of the present utility model, the heat exchange component 10, by providing a connecting member 4, and making the connecting member 4 usable for connecting the first heat exchange region 31 and the second heat exchange region 32, can avoid mutual constraints between the first heat exchange region 31 and the second heat exchange region 32, making the arrangement of the heat exchange flow channel more flexible, so that the first heat exchange region 31 and the second heat exchange region 32 can exchange heat with the corresponding components in a targeted manner, which can improve the heat exchange efficiency, help reduce the temperature difference, and improve the design rationality of the battery box 100.

[0070] In some embodiments of this utility model, the connecting member 4 can be constructed as a through pipe, and sealing members are provided at both ends of the connecting member 4. This reduces the difficulty of molding the connecting member 4.

[0071] In some embodiments of this utility model, such as Figure 4 As shown, the heat exchanger 3 is provided with a first connecting hole 33, and the connecting member 4 is provided with a corresponding second connecting hole 44. The first connecting hole 33 and the second connecting hole 44 are connected to connect the first heat exchange region 31 and the second heat exchange region 32. With the above arrangement, the relative positions of the first heat exchange region 31 and the second heat exchange region 32 are not restricted, so that the arrangement of the heat exchanger 3 is more flexible and the practicality of the heat exchange assembly 10 is improved.

[0072] In some embodiments of this utility model, such as Figure 7 As shown, the connecting member 4 is provided with a connecting plug 42, and a second connecting hole 44 is provided in the connecting plug 42. The connecting plug 42 is inserted into the first connecting hole 33.

[0073] Specifically, multiple connector plugs 42 can be provided on the connecting member 4, each connector plug 42 having a second connecting hole 44, and multiple first connecting holes 33 can be provided on the heat exchange member 3. The first heat exchange area 31 and the second heat exchange area 32 are respectively provided with a number of first connecting holes 33. The multiple connector plugs 42 correspond one-to-one with the multiple first connecting holes 33. The connector plugs 42 are inserted into the first connecting holes 33, and the first connecting holes 33 and the second connecting holes 44 are connected, so that the connecting member 4 can connect the first heat exchange area 31 and the second heat exchange area 32.

[0074] It should be noted that the number of first connection holes 33 needs to be determined according to design requirements. The more first connection holes 33 there are, the smaller the pressure drop and the faster the flow rate of the heat exchange medium.

[0075] The above settings can reduce the installation difficulty of the connecting part 4 and the heat exchanger 3, improve the connection stability between the connecting part 4 and the heat exchanger 3, and improve the reliability of the battery tray 100.

[0076] Of course, this utility model is not limited to this. Multiple connecting plugs 42 can be provided on the heat exchanger 3, and several connecting plugs 42 can be provided on the first heat exchange region 31 and the second heat exchange region 32 respectively. A first connecting hole 33 is formed within each connecting plug 42, and multiple second connecting holes 44 are provided on the connecting member 4. Each connecting plug 42 corresponds one-to-one with a second connecting hole 44. The connecting plug 42 is inserted into the second connecting hole 44, and the first connecting hole 33 communicates with the second connecting hole 44, so that the connecting member 4 can connect the first heat exchange region 31 and the second heat exchange region 32. This facilitates meeting different operating conditions.

[0077] In some embodiments of this utility model, such as Figure 4 As shown, the heat exchanger 3 is provided with a plurality of first connection holes 33, and the number of first connection holes 33 in the first heat exchange region 31 is greater than the number of first connection holes 33 in the second heat exchange region 32. This reduces pressure drop, increases the flow rate of the heat exchange medium, and improves the heat exchange efficiency of the heat exchange assembly 10.

[0078] In some embodiments of this utility model, such as Figure 7 As shown, the outer peripheral wall of the connecting member 4 can be provided with a connecting plane 41. The connecting member 4 is connected to the side wall of the heat exchange member 3 through the connecting plane 41, such as by adhesive bonding or welding. The connecting plane 41 has a protruding connecting plug 42. The side wall of the heat exchange member 3 is provided with a first connecting hole 33. The connecting plug 42 is used to be inserted into the first connecting hole 33 when the connecting plane 41 is connected to the side wall of the heat exchange member 3.

[0079] With the above settings, a large-area connection can be achieved between the connecting element 4 and the heat exchange element 3, which helps to improve the connection stability between the connecting element 4 and the heat exchange element 3.

[0080] In some embodiments of this utility model, such as Figure 7As shown, the connecting plane 41 is welded to the heat exchanger 3, such as by laser welding or brazing. The minimum distance between the connecting plug 42 and the edge of the connecting plane 41 can be set to H1, satisfying: H1 ≥ 3mm. That is, the minimum distance H1 between the connecting plug 42 and the edge of the connecting plane 41 can be greater than or equal to 3mm, such as 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. This ensures that the weld has a larger width, improving the connection stability between the connecting part 4 and the heat exchanger 3.

[0081] In some embodiments of this utility model, such as Figure 7 As shown, at least one connecting channel 43 is formed within the connecting member 4. The connecting channel 43 connects the first heat exchange region 31 and the second heat exchange region 32. The inner diameter of the connecting channel 43 can be set to R, satisfying: R≥12mm. That is, the inner diameter R of the connecting channel 43 can be set to be greater than or equal to 12mm, such as 12mm, 12.5mm, 13mm, 13.5mm, 14mm, etc. This reduces the flow resistance of the connecting member 4, increases the flow velocity of the heat exchange medium, and thus improves the heat exchange efficiency of the heat exchange member 3.

[0082] In some embodiments of this utility model, such as Figure 7 As shown, at least one connecting channel 43 is formed within the connecting member 4. The connecting channel 43 connects the first heat exchange region 31 and the second heat exchange region 32. The minimum wall thickness of the connecting channel 43 can be set to H2, satisfying: H2 ≥ 1 mm. That is, the minimum wall thickness H2 of the connecting channel 43 can be set to be greater than or equal to 1 mm, such as 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, etc. Therefore, the connecting member 4 can meet the burst pressure requirements, improving the reliability of the connecting member 4.

[0083] In some embodiments of this utility model, such as Figure 3 As shown, a first heat exchange channel and a second heat exchange channel can be provided within the first heat exchange zone 31. The first heat exchange channel and the second heat exchange channel are connected. The heat exchange assembly 10 also includes a heat exchange joint 5, which is located adjacent to the first heat exchange zone 31. The inlet of the heat exchange joint 5 is connected to the first heat exchange channel, and the outlet of the heat exchange joint 5 is connected to the second heat exchange channel. Specifically, the heat exchange medium in the external pipeline can flow into the first heat exchange channel through the inlet of the heat exchange joint 5, and the heat exchange medium in the second heat exchange channel can flow out to the external pipeline through the outlet of the heat exchange joint 5.

[0084] The above settings can reduce the difficulty of connecting the heat exchange channel inside the heat exchanger 3 with the external pipeline, and help improve the connection stability, thereby improving the reliability of the heat exchange assembly 10.

[0085] In some embodiments of this utility model, such as Figure 5 As shown, there are at least two connecting parts 4. A third heat exchange channel is provided in the second heat exchange zone 32. The first heat exchange channel is connected to the liquid inlet of the third heat exchange channel through the connecting part 4, and the second heat exchange channel is connected to the liquid outlet of the third heat exchange channel through another connecting part 4.

[0086] Specifically, the first cavity 51 houses the control module 300, and the second cavity 52 houses the battery module 200. The heat exchange medium in the external pipeline can flow into the first heat exchange channel to exchange heat with a portion of the control module 300. Then, the heat exchange medium can flow through the connecting member 4 to flow into the third heat exchange channel. The heat exchange medium flowing into the third heat exchange channel exchanges heat with the battery module 200. After heat exchange, the heat exchange medium flows through another connecting member 4 to flow into the second heat exchange channel. The heat exchange medium flowing into the second heat exchange channel exchanges heat with another portion of the control module 300. Then, the heat exchange medium can flow out into the external pipeline.

[0087] The above settings can reduce the difficulty of connecting the external pipeline to the heat exchanger 3, facilitate the installation of the battery box 100, and improve the design rationality of the battery box 100.

[0088] In some embodiments of this utility model, the area of ​​the portion of the first heat exchange region 31 with the first heat exchange channel is smaller than the area of ​​the portion of the first heat exchange region 31 with the second heat exchange channel. For example, the area of ​​the portion of the first heat exchange region 31 with the first heat exchange channel is set to 1 / 2, 1 / 3, 1 / 4, etc., of the area of ​​the portion of the first heat exchange region 31 with the second heat exchange channel.

[0089] It is understandable that the operating temperature of the control module 300 is higher than that of the cell module 200. When the first receiving cavity 51 contains the control module 300 and the second receiving cavity 52 contains the cell module 200, by setting the area of ​​the portion of the first heat exchange region 31 with the first heat exchange channel to be smaller than the area of ​​the portion of the first heat exchange region 31 with the second heat exchange channel, the amount of heat exchange before the heat exchange medium flows into the third heat exchange channel can be reduced, so that the temperature of the heat exchange medium flowing into the third heat exchange channel is lower, thereby increasing the temperature difference between the heat exchange medium and the cell module 200. This is beneficial to improving the heat exchange efficiency between the heat exchange medium and the cell module 200 and improving the working stability of the battery device 1000.

[0090] In some embodiments of this utility model, such as Figure 6 As shown, the heat exchanger 3 can be constructed as a single-piece molded part, with the first heat exchange region 31 and the second heat exchange region 32 spaced apart in different parts of the heat exchanger 3. This reduces the number of parts and lowers the assembly difficulty of the battery housing 100.

[0091] In some other embodiments of this utility model, the heat exchanger 3 can be configured to include a first heat exchanger and a second heat exchanger formed separately. The first heat exchanger has a first heat exchange region 31, and the second heat exchanger has a second heat exchange region 32. This reduces the molding difficulty of the heat exchanger 3 and decreases its overall size, thus saving material costs.

[0092] In some embodiments of this utility model, such as Figures 8-9 As shown, the heat exchanger 3 has a partition groove 36, which is used to separate the first heat exchange region 31 and the second heat exchange region 32. The connecting member 4 is disposed on one side of the partition groove 36 along the horizontal direction or spans across the partition groove 36. For example, the connecting member 4 can be disposed on one side of the partition groove 36 along the length direction; or, the connecting member can be provided to span across the partition groove 36.

[0093] The above settings can prevent heat exchange between the first heat exchange region 31 and the second heat exchange region 32, thereby improving the independence of the first heat exchange region 31 and the second heat exchange region 32 and enhancing the heat exchange effect of the heat exchange component 10.

[0094] This utility model also proposes a battery box 100.

[0095] like Figure 5 As shown, the battery housing 100 according to an embodiment of the present invention includes a heat exchange assembly 10 according to any of the above embodiments. Specifically, the heat exchange assembly 10 may be disposed inside the battery housing 100 or may be part of the battery housing 100; the present invention does not limit this.

[0096] According to the battery housing 100 of this utility model embodiment, the heat exchanger 3 can achieve targeted cooling, has high heat exchange efficiency, and helps to reduce temperature difference, thereby improving the practicality of the battery housing 100.

[0097] In some embodiments of the present invention, the battery box 100 of the present invention further includes: a frame 1 and a partition beam 2, the partition beam 2 being disposed within the frame 1, the heat exchange assembly 10, the partition beam 2 and the frame 1 respectively enclosing a first receiving cavity 51 and a second receiving cavity 52; the first heat exchange area 31 is located in the first receiving cavity 51, and the second heat exchange area 32 is located in the second receiving cavity 52.

[0098] For example, refer to Figures 1-7As shown, the battery housing 100 includes a frame 1, a partition beam 2, and a heat exchange assembly 10. The heat exchange assembly 10 includes a heat exchange element 3 and a connecting element 4. A receiving space is formed within the frame 1. The partition beam 2 is disposed within the receiving space of the frame 1. The two ends of the partition beam 2 are respectively connected to the opposite side walls of the frame 1. The partition beam 2 and the frame 1 respectively enclose a first receiving cavity 51 and a second receiving cavity 52. ​​The first receiving cavity 51 is used to receive one of the battery cell module 200 and the control module 300, and the second receiving cavity 52 is used to receive the other of the battery cell module 200 and the control module 300.

[0099] Of course, the first receiving cavity 51 and the second receiving cavity 52 can also be configured to accommodate different types of battery cell modules 200, such as lithium battery packs and sodium battery packs, solid-state batteries and lithium battery packs, etc., which will not be elaborated here.

[0100] The heat exchanger 3 is plate-shaped and has a heat exchange channel inside. The heat exchange channel is used to flow the heat exchange medium. The cooling medium can be any of the following materials: water, mineral oil, etc. The heat exchanger 3 is located at the bottom of the frame 1 and is connected to the frame 1. Alternatively, the heat exchanger 3 and the frame 1 can be connected by friction stir welding.

[0101] The heat exchanger 3 includes a first heat exchange region 31 and a second heat exchange region 32 that are separated from each other. Both the first heat exchange region 31 and the second heat exchange region 32 are provided with heat exchange channels. The first heat exchange region 31 is located at the bottom of the first receiving cavity 51 and is used to exchange heat with the components installed in the first receiving cavity 51. The second heat exchange region 32 is located at the bottom of the second receiving cavity 52 and is used to exchange heat with the components installed in the second receiving cavity 52.

[0102] For example, a first receiving cavity 51 may be provided to house the control module 300, and a second receiving cavity 52 may be provided to house the battery cell module 200. The first heat exchange area 31 is used to exchange heat with the control module 300, and the second heat exchange area 32 is used to exchange heat with the battery cell module 200.

[0103] The connecting member 4 is connected to the heat exchange member 3. The connecting member 4 is used to connect the heat exchange flow channel in the first heat exchange region 31 and the heat exchange flow channel in the second heat exchange region 32, so that the heat exchange medium can flow from one of the first heat exchange region 31 and the second heat exchange region 32 to the other, so that the heat exchange medium can exchange heat with the control module 300 and the battery module 200 respectively.

[0104] It is understandable that by connecting the first heat exchange area 31 and the second heat exchange area 32 through the connecting member 4, the mutual constraints between the first heat exchange area 31 and the second heat exchange area 32 can be avoided, making the arrangement of the heat exchange channels more flexible. This allows the first heat exchange area 31 and the second heat exchange area 32 to exchange heat with corresponding components (such as the cell module 200 and the control module 300) in a targeted manner. For example, arranging denser channels in higher temperature locations helps to improve heat exchange efficiency, reduces the temperature difference of corresponding components, and enables the battery device 1000 to work more stably. It also helps to reduce the design and processing difficulty of the heat exchange component 3 and improves the practicality of the battery box 100.

[0105] In some embodiments of this utility model, such as Figure 7 As shown, a mounting cavity 111 can be provided within the frame 1. The mounting cavity 111 is open towards the heat exchanger 3 and is used to accommodate the connecting member 4. With the above arrangement, the connecting member 4 can be effectively prevented from being bumped or damaged, and the connecting member 4 can be avoided from being squeezed by the expansion of the cell module 200, which improves the stability of the connecting member 4. It can also make full use of space and help reduce the overall size of the battery box 100.

[0106] Of course, this invention is not limited to this; the connecting member 4 can also be located on the side of the heat exchange member 3 away from the frame 1. This is beneficial for meeting different working conditions.

[0107] In some embodiments of this utility model, such as Figures 8-10 As shown, support bosses 6 can be provided on both the frame 1 and the partition beam 2. The support bosses 6 protrude inward and are used to support the battery cell module 200. The supporting surface of the support bosses 6 is not lower than that of the heat exchanger 3, and the support bosses 6 are used to support the battery cell module 200 above the heat exchanger 3. It should be noted that the control module 300 is connected to the frame 1 and the partition beam 2 by screws.

[0108] In existing technology, the cell module 200 is placed on a cold plate. Since the cold plate itself has poor strength, a support plate needs to be welded to the back of the cold plate for reinforcement. This solution suffers from complex operation and poor reliability. To address these issues, the cell module 200 can be supported on the frame 1 and the partition beam 2, eliminating the pressure exerted by the cell module 200 on the heat exchange component 3. This saves on support plates, simplifies the manufacturing process, and improves the overall structural strength of the battery housing 100.

[0109] In some embodiments of this utility model, the frame 1 includes: two side beams 11 arranged along the first direction F1 and a first end beam 12 and a second end beam 13 arranged along the second direction F2. The partition beam 2 extends along the first direction F1 and is connected to the side beams 11 at both ends. The connecting member 4 is installed on the side beams 11. The first end beam 12 and the partition beam 2 define a first receiving cavity 51, and the second end beam 13 and the partition beam 2 define a second receiving cavity 52. ​​The second end beam 13 and the partition beam 2 are provided with a supporting boss 6. The second direction F2 intersects with the first direction F1.

[0110] For example, refer to Figure 2 , Figure 3 and Figure 8 As shown, the frame 1 includes two side beams 11, a first end beam 12, and a second end beam 13. The two side beams 11 are arranged along a first direction F1, and the first end beam 12 and the second end beam 13 are arranged along a second direction F2. The two side beams 11, the first end beam 12, and the second end beam 13 are welded together to form the frame 1, such as by argon arc welding.

[0111] The partition beam 2 extends along the first direction F1, and its two ends along the first direction F1 are respectively connected to the side beam 11, such as by argon arc welding. The connecting piece 4 is installed on the side beam 11 and extends along the second direction F2 so that the ends of the connecting piece 4 can extend to both sides of the partition beam 2 along the second direction F2.

[0112] The first end beam 12, the side beam 11 and the partition beam 2 together define the first receiving cavity 51, and the second end beam 13, the side beam 11 and the partition beam 2 define the second receiving cavity 52. ​​The first receiving cavity 51 is provided with a first heat exchange area 31 below it, and the second receiving cavity 52 is provided with a second heat exchange area 32 below it. The connecting member 4 is located on both sides of the partition beam 2 along the second direction F2 and is respectively opposite to and connected to the first heat exchange area 31 and the second heat exchange area 32.

[0113] The second end beam 13 and the partition beam 2 each have a supporting boss 6 on their respective sides facing each other. The battery cell module 200 is installed in the second receiving cavity 52, and both ends of the battery cell module 200 along the second direction F2 are supported on the supporting bosses 6. It should be noted that the first direction F1 and the second direction F2 intersect. For example, the first direction F1 can be set at... Figure 3 The left and right directions are shown, and the second direction F2 is set as... Figure 3 The front and back directions are shown.

[0114] The above-mentioned design simplifies the structure of the battery box 100, reduces the molding difficulty of the battery box 100, and improves the practicality of the battery box 100.

[0115] In some embodiments of this utility model, such as Figure 9As shown, the support boss 6 includes a first support boss 21 provided on the partition beam 2. The support surface of the first support boss 21 can be set as a first support surface 22. The first support surface 22 is used to support the battery cell module 200. In the second direction F2, the minimum width of the first support surface 22 is W1, which satisfies: 30mm≥W1≥10mm.

[0116] In other words, the minimum width W1 of the first support surface 22 can be set to be greater than or equal to 30mm and less than or equal to 10mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, etc. Through the above settings, the overlap width between the partition beam 2 and the cell module 200 can be larger, which is beneficial to improving the installation stability of the cell module 200 and improving the overall stability of the battery device 1000.

[0117] In some embodiments of this utility model, such as Figure 10 As shown, the support boss 6 includes a second support boss 131 provided on the second end beam 13. The support surface of the second support boss 131 can be set as a second support surface 132. The second support surface 132 is used to support the battery cell module 200. In the second direction F2, the minimum width of the second support surface 132 is W2, which satisfies: 30mm≥W2≥10mm.

[0118] In other words, the minimum width W2 of the second support surface 132 can be set to be greater than or equal to 30mm and less than or equal to 10mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, etc. Through the above settings, the overlap width between the second end beam 13 and the cell module 200 can be larger, which is beneficial to improving the installation stability of the cell module 200 and improving the overall stability of the battery device 1000.

[0119] In some embodiments of this utility model, such as Figure 7 As shown, the heat exchanger 3 includes a heat spreader 34 and a flow channel plate 35. The heat spreader 34 is connected to the frame 1 and is used for heat exchange with the control module 300 and the battery module 200. The flow channel plate 35 is located on the side of the heat spreader 34 away from the frame 1, and the flow channel plate 35 and the heat spreader 34 together define the heat exchange flow channel. This reduces the molding difficulty of the heat exchanger 3.

[0120] This utility model also proposes a battery device 1000.

[0121] like Figures 1-2As shown, the battery device 1000 according to an embodiment of the present invention includes: a battery housing 100, a cell module 200, and a control module 300. The battery housing 100 is the battery housing 100 according to any of the above embodiments. The cell module 200 is disposed inside the battery housing 100 and exchanges heat with the second heat exchange area 32. The control module 300 is electrically connected to the cell module 200 and is disposed inside the battery housing 100 and exchanges heat with the first heat exchange area 31.

[0122] According to the battery device 1000 of this utility model embodiment, the heat exchanger 3 can achieve targeted cooling for different components, with high heat exchange efficiency and the ability to eliminate temperature differences, thereby improving the overall thermal safety of the battery device 1000.

[0123] This utility model also proposes a battery device 1000.

[0124] like Figures 1-2 As shown, the battery device 1000 according to an embodiment of the present invention includes: a battery housing 100, a first battery cell module, and a second battery cell module. The battery housing 100 is the battery housing 100 according to any of the above embodiments. The first battery cell module is disposed inside the battery housing 100 and exchanges heat with the second heat exchange region 32. The second battery cell module is disposed inside the battery housing 100 and exchanges heat with the first heat exchange region 31. The cells of the first battery cell module and the cells of the second battery cell module are different.

[0125] It should be noted that the first and second cell modules can be different types of cell modules, such as lithium battery packs and sodium battery packs, solid-state batteries and lithium battery packs, or they can be cell modules of different sizes but the same type.

[0126] According to the battery device 1000 of this utility model embodiment, the heat exchanger 3 can achieve targeted cooling for different cell modules 200, with high heat exchange efficiency and the ability to eliminate temperature differences, thereby improving the overall thermal safety of the battery device 1000.

[0127] In some embodiments of this utility model, the frame 1 and the partition beam 2 are respectively provided with support bosses 6 for supporting the battery cell module 200. The support surface of the support bosses 6 is not lower than the heat exchange component 3. The battery cell module 200 is supported on the support bosses 6 at both ends in the second direction F2. The size of the part of each support surface that mates with the battery cell module 200 is L1. The length of the battery cell module 200 in the second direction F2 is L. The value range of L1 / L is 0.8%-30%.

[0128] For example, refer to Figures 8-10As shown, the frame 1 and the partition beam 2 are respectively provided with support bosses 6 for supporting the battery cell module 200. The support surface of the support bosses 6 is not lower than the heat exchanger 3. The battery cell module 200 is supported on the support surface of the support bosses 6 at both ends of the second direction F2, so as to fix the battery cell module 200 above the heat exchanger 3, so that the lower side wall of the battery cell module 200 can exchange heat with the heat exchanger 3.

[0129] Specifically, the dimension of each support surface mating with the cell module 200 can be set as L1 (including W1 and W2), and the length of the cell module 200 in the second direction F2 can be set as L. The value of L1 / L ranges from 0.8% to 30%. That is, the ratio of the dimension L1 of each support surface mating with the cell module 200 to the length L of the cell module 200 in the second direction F2 can be set to be greater than or equal to 0.8% and less than or equal to 30%, such as 0.8%, 1%, 5%, 10%, 15%, 20%, 25%, 30%, etc.

[0130] The above settings allow for a larger overlap between the support surface and the cell module 200, which improves the installation stability of the cell module 200 and enhances the overall reliability of the battery device 1000.

[0131] In some embodiments of this utility model, such as Figures 1-2 As shown, the battery device 1000 also includes a battery sealing cover 400 and a maintenance cover 500. The battery sealing cover 400 is disposed on the frame 1 and is used to seal the receiving cavity. The battery sealing cover 400 has a maintenance port 401 corresponding to the first receiving cavity 51. The maintenance cover 500 is detachably installed in the battery sealing cover 400 and is used to seal the maintenance port 401. In this way, the control module 300 can be maintained by removing and installing the maintenance cover 500. This reduces the difficulty of maintenance and improves the design rationality of the battery device 1000.

[0132] In some embodiments of this utility model, such as Figure 2 As shown, the battery device 1000 also includes a bottom protective plate 600. The bottom protective plate 600 is disposed on the side of the heat exchanger 3 away from the frame 1 and is adhesively bonded to the heat exchanger 3. The bottom protective plate 600 can be a one-piece molded part, and the bottom protective plate 600 is used to protect the heat exchanger 3. This can improve the structural stability of the battery device 1000.
