[0003] The present application relates to the technical field of cooling plates, and in particular to a battery cooling plate, a chemical compartment of a vehicle body, a vehicle body, and a vehicle. Background Art

[0004] In related technologies, when a battery cooling plate is subjected to impacts such as being stepped on, hit by objects, or struck, the flow channel is prone to collapse, causing the battery's thermal management function to deteriorate or even be lost.

[0005] Summary of the Invention

[0006] An embodiment of the present application provides a battery cooling plate that can reduce the risk of flow channel collapse.

[0007] In a first aspect, an embodiment of the present application provides a battery cooling plate, comprising: a plate body having a flow channel for circulating a heat exchange medium; a reinforcement member, the reinforcement member being connected to the plate body and at least used to strengthen the strength of the area on the plate body where the flow channel is located.

[0008] In the above technical solution, the strength of the flow channel area on the plate body is strengthened by the reinforcement member, thereby improving the overall impact resistance of the battery cooling plate, thereby reducing the risk of plastic deformation of the battery cooling plate and the risk of flow channel collapse, thereby improving the stability of the thermal management function.

[0009] In some embodiments, the plate body includes an impacted area, and the impacted area is correspondingly provided with the reinforcement.

[0010] In the above technical solution, reinforcements are provided corresponding to the impacted areas, so that the reinforcements can specifically improve the structural strength of the impacted areas and better reduce the risk of collapse of the impacted areas.

[0011] In some embodiments, the reinforcement is disposed in the flow channel and connected to a wall of the flow channel.

[0012] In this technical solution, the reinforcement not only connects to the channel wall to enhance the wall's structural strength and reduce deformation, but also provides support by occupying space within the channel when the channel wall deforms, minimizing further deformation. This resolves the channel collapse issue and reduces thermal management degradation. The reinforcement also increases the heat exchange area with the heat exchange medium, improving heat exchange efficiency.

[0013] In some embodiments, the plate body includes a first heat exchange region opposite to the high temperature region of the chemical chamber and a second heat exchange region opposite to the low temperature region of the chemical chamber, and the reinforcement is provided in the flow channel of the second heat exchange region.

[0014] In the above technical solution, the heat exchange medium flowing into the first heat exchange area is excess to the heat exchange medium flowing into the second heat exchange area. The heat exchange capacity of the first heat exchange area is stronger than that of the second heat exchange area, so that the heat exchange efficiency with the high-temperature area is higher than that with the low-temperature area, which is beneficial to reducing the temperature difference between the high-temperature area and the low-temperature area, and making the temperature distribution of the chemical chamber more uniform.

[0015] In some embodiments, the flow channel extends along a set direction, and a dimension of the reinforcement perpendicular to the set direction is less than or equal to a dimension of the flow channel perpendicular to the set direction.

[0016] In the above technical solution, the dimension of the reinforcement perpendicular to the set direction is equal to the dimension of the flow channel perpendicular to the set direction, so that both sides of the reinforcement perpendicular to the set direction are in contact with the wall surface of the flow channel, and the reinforcement provides more reliable support and reinforcement for the plate body. The dimension of the reinforcement perpendicular to the set direction is smaller than the dimension perpendicular to the set direction. Under the premise of meeting strength requirements, the space occupied by the reinforcement in the flow channel can be reduced, thereby improving heat exchange efficiency. Moreover, even if the plate body deforms to a certain extent, causing the dimension of the flow channel perpendicular to the set direction to deform, the support and limit of the reinforcement can still ensure that the flow channel retains a certain flow capacity, avoiding loss of thermal management function.

[0017] In some embodiments, the flow channel extends along a set direction, and the reinforcement has a channel penetrating along the set direction.

[0018] In the above technical solution, heat exchange medium can also flow in the channel of the reinforcement. On the premise that the reinforcement has a sufficiently large size perpendicular to the set direction to improve the strength, the reduction in the flow area of ​​the flow channel can be reduced, and sufficient heat exchange medium can flow in the flow channel to meet the heat exchange requirements.

[0019] In some embodiments, the reinforcement includes a connecting portion and multiple bending portions, the multiple bending portions are arranged perpendicular to the set direction, the bending portion has a channel groove on the side facing the connecting portion, the connecting portion covers the notch of the channel groove to define the channel, and the connecting portion is connected to the wall of the flow channel.

[0020] In the above technical solution, the structure formed by the bending portion and the connecting portion has high compressive strength, has a better effect of improving the structural strength of the battery cooling plate, and is simple to form, which is conducive to reducing the production cost of the reinforcement.

[0021] In some embodiments, the reinforcement includes an outer peripheral wall and a partition wall, wherein the partition wall is disposed in the space enclosed by the outer peripheral wall to divide the space enclosed by the outer peripheral wall into a plurality of the channels.

[0022] In the above technical solution, the reinforcement formed by the outer peripheral wall and the partition wall has high compressive strength, is more effective in improving the structural strength of the battery cooling plate, and is simple to form, which is conducive to reducing the production cost of the reinforcement.

[0023] In some embodiments, the reinforcement is in surface contact with the wall of the flow channel.

[0024] In the above technical solution, by the surface contact between the reinforcement and the wall of the flow channel, on the one hand, the connection strength and support stability between the reinforcement and the plate body can be increased, thereby improving the strength of the battery cooling plate; on the other hand, the heat exchange between the reinforcement and the plate body can be enhanced, thereby improving the heat exchange efficiency.

[0025] In some embodiments, the reinforcement is made of a corrosion-resistant material, or a corrosion-resistant material layer is provided on the surface of the reinforcement.

[0026] In the above technical solution, the corrosion-resistant material is not easy to react with the heat exchange medium. By making the entire reinforcement member of corrosion-resistant material or providing a corrosion-resistant material layer on the surface, the entire reinforcement member is not easy to react with the heat exchange medium or the exposed part is not easy to react with the heat exchange medium, which is beneficial to improving the service life of the reinforcement member and enhancing the structural stability of the battery cooling plate.

[0027] In some embodiments, the reinforcement member includes a first thinned region connected to a wall of the flow channel.

[0028] In the above technical solution, the thickness of the first thinned area is relatively small, so that the reinforcement can be connected to the wall of the flow channel through the area with smaller thickness, making the connection more convenient and firm.

[0029] In some embodiments, the first thinned area is a notch provided in the reinforcement member, the reinforcement member has channels located on both sides of the notch, and the notch connects the channels on both sides.

[0030] In the above technical solution, the notch groove can allow the heat exchange medium to circulate and connect the channels on both sides, so that the first thinned area used to connect with the plate body will not interfere with the flow of the heat exchange medium, which is conducive to improving the heat exchange efficiency.

[0031] In some embodiments, there are a plurality of reinforcement members, at least two of the reinforcement members include a second thinned region, and the second thinned regions of the two reinforcement members are stacked.

[0032] In the above technical solution, the stacked second thinned regions of the two reinforcements enhance the overall structural strength of the multiple reinforcements, further improving the structural strength of the battery cooling plate. Furthermore, the stacked second thinned regions reduce the overall thickness of the overlapping region between the two reinforcements, making the overlap more space-efficient and less likely to interfere with other structures.

[0033] In some embodiments, the reinforcement member has a channel, and the channel is partially located in the second thinned region.

[0034] In the above technical solution, the second thinned area does not block the circulation of the heat exchange medium in the channel, and the heat exchange medium in the reinforcement member flows smoothly.

[0035] In some embodiments, the plate body includes a first plate body and a second plate body, the first plate body is provided with a groove on the side facing the second plate body, the second plate body covers the notch of the groove to define the flow channel, and the reinforcement is connected to the first plate body or the second plate body.

[0036] In the above technical solution, the method of defining the flow channel is simple, and it is easy to realize a complex flow channel connection structure and to facilitate the assembly of reinforcement parts.

[0037] In a second aspect, an embodiment of the present application further provides a chemical compartment of a vehicle body, comprising the above-mentioned battery cooling plate.

[0038] In a third aspect, an embodiment of the present application further provides a vehicle body, comprising the chemical chamber of the above-mentioned vehicle body.

[0039] In some embodiments, the battery cooling plate is a floor of the vehicle body.

[0040] In this technical solution, the battery cooling plate not only serves as thermal management but also serves as the passenger compartment floor. This reduces the number of vehicle components and space, providing more space for battery installation, thereby improving energy density. Furthermore, by including reinforcements to enhance the strength of the battery cooling plate, the plate is less susceptible to impacts such as footsteps and objects hitting the floor, which could degrade or even eliminate its thermal management function. This improves the vehicle's service life and user experience.

[0041] In a fourth aspect, the present application also provides a vehicle comprising the above-mentioned vehicle body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0056] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0058] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0059] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0060] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0061] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0062] The term "plurality" used in this application refers to two or more (including two).

[0063] Batteries can be used in, but are not limited to, electrical devices such as vehicles, ships, or aircraft. Batteries and other components can form the power supply system of such devices to ensure the safety and reliability of the devices. For example, electrical devices can include, but are not limited to, vehicles, mobile phones, tablets, laptops, ships, spacecraft, electric toys, and power tools. Vehicles can be fuel-powered, gas-powered, new energy vehicles, or rail vehicles. New energy vehicles can include pure electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles, extended-range electric vehicles, and fuel cell vehicles.

[0064] The vehicle body refers to the arrangement of the various components that make up the vehicle. For example, the vehicle body can include an upper body and a lower body. The upper body refers to the portion of the vehicle used to transport passengers and cargo, and may include, for example, windows, doors, the cockpit, and the passenger compartment. The lower body may include the front cabin assembly, chemical compartment, and rear floor assembly.

[0065] The front compartment assembly is used to transfer frontal collision loads. For example, it may include a front anti-collision beam, two front longitudinal beams, and two front torsion boxes. The front ends of the two front longitudinal beams are connected to the ends of the front anti-collision beam, and the rear ends of the two front longitudinal beams are connected to the two front torsion boxes. The front torsion boxes are connected to the chemical chamber. When the vehicle is hit, the front anti-collision beam evenly bears the expansion load, and the collision load is shared by the two front longitudinal beams and the corresponding two front torsion boxes, minimizing damage to the passenger compartment.

[0066] The rear floor assembly is the mounting platform for interior and exterior trim, electrical components, and other system components. It carries passengers, houses the spare tire, and, during a rear-end collision, deforms to minimize fuel tank damage and passenger load. For example, the rear floor assembly may include a rear anti-collision beam, two rear longitudinal beams, two rear torsion boxes, a rear crossbeam, and a rear floor. The rear ends of the two rear longitudinal beams are connected to the ends of the rear anti-collision beam, while the front ends of the two rear longitudinal beams are connected to the two rear torsion boxes. The rear torsion boxes are connected to the battery assembly, while the rear crossbeam connects the two rear torsion boxes. The rear floor is installed between the two rear longitudinal beams.

[0067] A chemical tank is a physical module that contains one or more battery cells to provide higher voltage and capacity. For example, a chemical tank may include a tank body for encapsulating one or more battery cells or battery modules. The tank body can reduce or prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. In addition, the tank body can not only be used to accommodate battery cells, but can also be used to connect to the front cabin assembly and rear floor assembly, serving as a load-bearing and force-transmitting structure of the vehicle body.

[0068] Battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the present application does not limit this. Battery cells may be cylindrical, flat, rectangular, or other shapes, etc., and the present application does not limit this. Battery cells are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and the present application does not limit this.

[0069] For example, a battery cell may include a housing, an electrode assembly, and an electrolyte. The housing houses the electrode assembly and electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets.

[0070] During battery operation, batteries need to operate within a suitable temperature range, which necessitates temperature regulation. For example, a battery cooling plate can be used to heat the battery at low temperatures and dissipate heat at high temperatures. The battery cooling plate can be located inside the battery housing, outside the battery housing, or as part of the battery housing to achieve heat exchange with the battery, particularly regulating the temperature of the battery cells and providing thermal management.

[0071] Battery cooling plates can be stamped or blown. A stamped cold plate is a battery cooling plate with a flow channel, formed by stamping a flow channel plate and a heat sink plate, then joining them together through processes such as brazing. A blown cold plate is a battery cooling plate with a flow channel, formed by thermoplastically inflating the plate body by passing inflation gas between the two layers of the plate body. For example, a battery cooling plate may include a flow channel plate and a heat sink plate. The main body of the heat sink plate is a large flat plate, one flat surface of which is bonded to the flow channel plate and brazed, and the other flat surface is bonded to the heat sink surface of the battery cell.

[0072] The flow channel of the battery cooling plate can pass through a heat exchange medium, which can be a coolant or water. The heat exchange medium can exchange heat with the battery through the wall of the flow channel, thereby achieving temperature regulation of the battery.

[0073] If the battery cooling plate is subjected to impacts such as being stepped on, crushed by objects, or hit by external forces, it is prone to plastic deformation. More obvious plastic deformation will cause the flow channel to collapse, resulting in a decline in the thermal management function or loss of function. For example, in some embodiments, the battery cooling plate is used as the bottom guard plate of a chemical chamber, which is used in a vehicle, and the bottom guard plate is subjected to external force impact from the bottom of the vehicle; for another example, in some embodiments, the chemical chamber is used in a vehicle, and the battery cooling plate is used as the upper side of the battery and serves as the floor of the passenger compartment. The battery cooling plate is often stepped on by passengers and crushed by objects. Although carpet can be laid on the upper part of the battery cooling plate for cushioning, it will still undergo plastic deformation when it encounters stronger stepping or crushing by heavier objects.

[0074] Based on this, the present application proposes a battery cooling plate 100, comprising a plate body 10 and a reinforcement 20. The plate body 10 has a flow channel 101 for circulating a heat exchange medium. The reinforcement 20 is connected to the plate body 10 and is used to strengthen at least the area of ​​the plate body 10 where the flow channel 101 is located.

[0075] In the battery cooling plate 100 of the above-mentioned structure, the strength of at least the area where the flow channel 101 is located on the plate body 10 is strengthened by the reinforcement 20, thereby improving the overall impact resistance of the battery cooling plate 100, thereby reducing the risk of plastic deformation in the area where the flow channel 101 is located on the battery cooling plate 100, and reducing the risk of collapse of the flow channel 101, thereby improving the stability of the thermal management function of the chemical chamber 1000.

[0076] The battery cooling plate 100 disclosed in the embodiment of the present application can be used in a chemical chamber 1000, and the chemical chamber 1000 can be used in a vehicle 3000. The vehicle 3000 can be a fuel vehicle, a gas vehicle, a new energy vehicle, or a rail vehicle, wherein the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, a plug-in hybrid vehicle, an extended-range electric vehicle, and a fuel cell powered vehicle, etc.

[0077] Hereinafter, a battery cooling plate 100 according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0078] Please refer to Figures 1 to 5. Figure 1 is a schematic structural diagram of a battery cooling plate 100 provided in an embodiment of the present application; Figure 2 is a top view of Figure 1; Figure 3 is an exploded view of Figure 1; Figure 4 is a cross-sectional view of Figure 2 along the direction indicated by line AA; and Figure 5 is an enlarged structural diagram of the area circled at B in Figure 4. The battery cooling plate 100 includes: a plate body 10 and a reinforcement 20. The plate body 10 has a flow channel 101 for circulating a heat exchange medium. The reinforcement 20 is connected to the plate body 10, and the reinforcement 20 is used to at least strengthen the strength of the area on the plate body 10 where the flow channel 101 is located.

[0079] The plate body 10 defines a flow channel 101 for allowing a heat exchange medium to flow, so that the heat exchange medium exchanges heat with the chemical chamber 1000 through the plate body 10 , thereby achieving thermal management of the chemical chamber 1000 .

[0080] The reinforcement 20 is connected to the plate body 10. Here, the reinforcement 20 can be arranged outside the flow channel 101 or inside the flow channel 101 and connected to the plate body 10; the reinforcement 20 can be directly arranged in the area where the flow channel 101 is located, or it can be arranged in an area near the area where the flow channel 101 is located. It only needs to be able to improve the structural strength of the area where the flow channel 101 is located on the plate body 10 and reduce the risk of plastic deformation of the plate body 10 causing collapse of the flow channel 101.

[0081] Of course, according to the requirements of anti-plastic deformation of other areas of the plate body 10, it can also be set in other areas of the plate body 10 to enhance the strength of the area where the non-flow channel 101 of the plate body 10 is located, which is also within the scope of protection of this application.

[0082] It should also be noted that the reinforcement member 20 can strengthen the strength of the area where the flow channel 101 is located. This can be done by strengthening the strength of the entire area where the flow channel 101 is located, or by strengthening the strength of the area where part of the flow channel 101 is located. For example, the location of the reinforcement member 20 can be determined based on whether the area where the flow channel 101 is located is susceptible to impact, thereby reducing the number of reinforcement members 20 used while still improving strength and reducing costs.

[0083] In some embodiments where the reinforcement 20 is disposed outside the flow channel 101, the connection between the reinforcement 20 and the plate body 10 is utilized to enhance the structural strength of the plate body 10. Furthermore, the reinforcement 20 may extend beyond the surface of the plate body 10 so that the reinforcement 20 withstands the impact force before the plate body 10, thereby preventing the impact force from directly impacting the wall of the channel 201 and causing severe collapse of the channel 201. For example, the plate body 10 may be bent and extended so that the convex area of ​​the outer surface corresponds to the flow channel 101 and the concave area corresponds to the non-flow channel 101 area. The reinforcement 20 may be connected to the concave area and be higher than the convex area. This allows the reinforcement 20 to buffer the force when impacted and then transfer it to the non-flow channel 101 area, preventing the impact force from directly impacting the convex area, thereby effectively reducing deformation of the wall of the flow channel 101.

[0084] In the embodiment where the reinforcement 20 is disposed within the flow channel 101 and connected to the wall of the flow channel 101, the reinforcement 20 can not only be used to connect to the wall of the flow channel 101 to improve the wall's structural strength and reduce deformation, but also, when the wall of the flow channel 101 deforms, the reinforcement 20 can occupy space within the flow channel 101 to provide support, thereby reducing further deformation of the flow channel 101 wall, thereby resolving the problem of flow channel 101 collapse and reducing the degradation of thermal management functions. The reinforcement 20 can also increase the heat exchange area with the heat exchange medium, improving heat exchange efficiency.

[0085] The reinforcement 20 may be connected to the panel body 10 by methods including, but not limited to, welding, clamping, riveting, and other methods. The reinforcement 20 may be formed by methods including, but not limited to, extrusion, bending, stamping, and 3D printing. The reinforcement 20 may have a shape including, but not limited to, a plate, a tube, a frame, or a mesh.

[0086] According to the battery cooling plate 100 of the embodiment of the present application, the strength of at least the area where the flow channel 101 is located on the plate body 10 is strengthened by the reinforcement 20, thereby improving the overall impact resistance of the battery cooling plate 100, thereby reducing the risk of plastic deformation in the area where the flow channel 101 is located on the battery cooling plate 100, and reducing the risk of collapse of the flow channel 101, thereby improving the stability of the thermal management function of the chemical chamber 1000.

[0087] According to some embodiments of the present application, as shown in FIG. 2 , the plate body 10 includes an impacted area 102 , and a reinforcement 20 is correspondingly provided in the impacted area 102 .

[0088] The impact zone 102 is the area of ​​the battery cooling plate 100 that is most susceptible to impact during use. For example, if the battery cooling plate 100 is used as a passenger compartment floor, the entire floor area, excluding the center console, front seats, and rear seat cushions, is located within the passenger compartment, where footrests and heavy objects are most likely to strike. These areas constitute the impact zone 102 of the plate body 10.

[0089] Compared to other areas, the flow channel 101 in the impacted area 102 is at a higher risk of collapse. Installing reinforcements 20 in the impacted area 102 allows the reinforcements 20 to specifically enhance the structural strength of the impacted area 102, effectively reducing the risk of collapse in the impacted area 102. Areas outside the impacted area 102 can be equipped with reinforcements 20 as needed to further enhance the overall strength of the battery cooling plate 100, or they can be omitted to reduce costs.

[0090] In some embodiments in which the reinforcement 20 is disposed in the flow channel 101, as shown in Figures 4 and 5, the plate body 10 includes a first heat exchange region opposite to the high-temperature region of the chemical chamber 1000 and a second heat exchange region opposite to the low-temperature region of the chemical chamber 1000, and the reinforcement 20 is disposed in the flow channel 101 of the second heat exchange region.

[0091] For the chemical chamber 1000, there are differences in temperature in different areas during operation. For example, the temperature in the area with denser battery cells is higher, and the temperature in the area with fewer battery cells is lower. For another example, the temperature in the area near the center of the chemical chamber 1000 is higher, and the temperature in the area near the edge of the chemical chamber 1000 is lower. Of course, the temperature difference distribution includes but is not limited to this.

[0092] The placement of reinforcement 20 within flow channel 101 reduces the actual flow area of ​​flow channel 101, thereby reducing the flow of heat exchange medium into the area where reinforcement 20 is located, thereby changing the flow distribution of the heat exchange medium throughout the battery cooling plate 100. By placing reinforcement 20 within flow channel 101 in the second heat exchange region, while omitting reinforcement 20 within flow channel 101 in the first heat exchange region, excess heat exchange medium flowing into the first heat exchange region flows into the second heat exchange region. This results in a stronger heat exchange capacity for the first heat exchange region than for the second heat exchange region, resulting in a higher heat exchange efficiency with the high-temperature region of the chemical chamber 1000 than with the low-temperature region. This helps reduce the temperature difference between the high-temperature and low-temperature regions and achieves a more uniform temperature distribution within the chemical chamber 1000.

[0093] In addition, the reinforcement 20 is provided with a flow channel 101 which can also contact the heat exchange medium, so that the reinforcement 20 and the plate body 10 can simultaneously exchange heat with the heat exchange medium, thereby increasing the heat exchange area and enhancing the heat exchange effect.

[0094] According to some embodiments of the present application, please refer to Figures 3-8, where Figures 6-8 are schematic diagrams of partial structures of the first plate body 11 and the reinforcement member 20 provided in embodiments of the present application. The plate body 10 includes a first plate body 11 and a second plate body 12. The first plate body 11 has a groove 111 on the side facing the second plate body 12. The second plate body 12 covers the notch of the groove 111 to define the flow channel 101. The reinforcement member 20 is connected to the first plate body 11 or the second plate body 12.

[0095] The first plate 11 has a groove 111 on the side facing the second plate 12. The side of the first plate 11 facing away from the second plate 12 can have a corresponding concave-convex structure or can be flat. For example, the first plate 11 can be deformed through sheet metal processing to form a groove 111 and a protrusion on one side, and a protrusion corresponding to the position of the groove 111 and a concave corresponding to the position of the protrusion on the other side. The first plate 11 is simple to form, and the concave-convex structure acts as a reinforcing rib, enhancing the overall structural strength of the first plate 11.

[0096] The second plate 12 seals the notch of the groove 111 to define the flow channel 101. This simple method for defining the flow channel 101 facilitates complex flow channel 101 connectivity structures and facilitates assembly. During assembly, the first plate 11 and the second plate 12 can be machined first, and then the reinforcement 20 can be connected to the first plate 11 or the second plate 12, and then the first plate 11 and the second plate 12 can be connected. Alternatively, the first plate 11 and the second plate 12 can be machined first, and then the reinforcement 20 can be placed in the groove 111, and then the first plate 11, the second plate 12, and the reinforcement 20 can be connected.

[0097] In addition, a larger area of ​​the second plate body 12 can be in the form of a flat plate, which, on the one hand, facilitates the coordinated heat exchange between the second plate body 12 and the chemical chamber 1000, for example, facilitating thermal contact between the second plate body 12 and the heat dissipation surface of the battery cell; on the other hand, it facilitates the connection between the second plate body 12 and the first plate body 11. For example, as shown in Figure 5, the second plate body 12 and the first plate body 11 can be in surface contact to increase the area of ​​the connection area and improve the structural strength of the plate body 10.

[0098] In some specific embodiments, the first plate 11 can be formed as a flow channel 101 plate, and the second plate 12 can be formed as a heat dissipation plate, which is used to make thermal contact with the battery cells of the chemical chamber 1000 to achieve heat exchange with the battery cells, and then achieve heat exchange with the heat exchange medium.

[0099] In some embodiments of the present application, the flow channel 101 extends along a set direction, and a dimension of the reinforcement 20 perpendicular to the set direction is less than or equal to a dimension of the flow channel 101 perpendicular to the set direction.

[0100] The flow channel 101 extends along a set direction, which means that the heat exchange medium in the flow channel 101 flows generally along the set direction. It should be noted that the extension direction of the flow channel 101 in different areas of the plate body 10 can be different. For example, as shown in FIG2 , the plate body 10 is generally a rectangular plate with a length direction parallel to the front-to-back direction and a width direction parallel to the left-to-right direction. Some flow channels 101 on the plate body 10 extend in the front-to-back direction, some extend in the left-to-right direction, some run from front to back and tilt to the left, and some run from front to back and tilt to the left. Of course, the structure and extension direction of the flow channel 101 and the plate body 10 include but are not limited to this.

[0101] The dimension of the reinforcement 20 perpendicular to the set direction can be any dimension of the reinforcement 20 perpendicular to the set direction, such as the dimension along the thickness of the panel body 10. For example, in the areas shown in Figures 4 and 5 , the set direction is the left-right direction, and the dimension of the reinforcement 20 perpendicular to the set direction is the up-down dimension or the fore-aft dimension. The dimension of the flow channel 101 perpendicular to the set direction refers to the dimension of the panel body 10 when it is undeformed.

[0102] The dimension of the reinforcement 20 perpendicular to the set direction is equal to the dimension of the flow channel 101 perpendicular to the set direction, so that both sides of the reinforcement 20 perpendicular to the set direction are in contact with the wall surface of the flow channel 101, and the reinforcement 20 provides a more reliable support and reinforcement effect on the plate body 10. The dimension of the reinforcement 20 perpendicular to the set direction is smaller than the dimension perpendicular to the set direction. Under the premise of meeting the strength requirements, the space occupied by the reinforcement 20 in the flow channel 101 can be reduced, thereby improving the heat exchange efficiency. Moreover, even if the plate body 10 undergoes a certain deformation, causing the dimension of the flow channel 101 perpendicular to the set direction to deform, the support and limit of the reinforcement 20 can still enable the flow channel 101 to retain a certain flow capacity, avoiding the loss of thermal management function.

[0103] According to some embodiments of the present application, as shown in Figures 5 and 9-11, which are schematic structural diagrams of the reinforcement member 20 provided in the first to third embodiments of the present application, the flow channel 101 extends along a set direction, and the reinforcement member 20 has a channel 201 penetrating along the set direction.

[0104] In other words, heat exchange medium can also flow through the channel 201 of the reinforcement 20. On the premise that the reinforcement 20 has a sufficiently large size perpendicular to the set direction to improve the strength, the reduction in the flow area of ​​the flow channel 101 can be reduced, and sufficient heat exchange medium can flow through the flow channel 101 to meet the heat exchange requirements.

[0105] It should be noted that the channel 201 may extend along a set direction, may extend at a certain angle relative to the set direction, or may extend in an arc, curve, or other path. The channel 201 extending along the set direction means that the inlet of the channel 201 is located upstream of the outlet of the channel 201 in the set direction, so that the heat exchange medium in the flow channel 101 can enter the channel 201 through the inlet of the channel 201 and flow out through the outlet, and the resistance of the heat exchange medium flowing through the channel 201 is small.

[0106] The specific structure of the reinforcement member 20 defining the channel 201 can be flexibly configured. For example, in some embodiments, as shown in Figures 5 and 9 (Figure 9 is a schematic diagram of the structure of the reinforcement member 20 provided in the first embodiment of this application), the reinforcement member 20 includes a connecting portion 21 and a plurality of bent portions 22. The bent portions 22 are arranged perpendicular to a predetermined direction. The bent portions 22 have a channel groove on one side facing the connecting portion 21. The connecting portion 21 covers the notch of the channel groove to define the channel 201. The connecting portion 21 is connected to the wall surface of the flow channel 101.

[0107] The bent portion 22 is a plate extending along a non-planar surface, so that the surface of the bent portion 22 facing the connecting portion 21 includes a recessed area to define a channel groove. For example, the bent portion 22 shown in Figures 5 and 9 is an arc-shaped plate, and the channel groove is a semi-cylindrical groove.

[0108] The connection can be in any shape, such as a flat plate or an arcuate plate. The connection between the connection portion 21 and the wall of the flow channel 101 can be point contact, surface contact, or line contact, and the connection method can be welding, clamping, riveting, etc. The connection portion 21 and the bent portion 22 can be integrally formed or connected by welding or other methods.

[0109] The multiple bends 22 are arranged perpendicular to the set direction, so that the multiple channel grooves are arranged perpendicular to the set direction. The resulting multiple channels 201 are arranged perpendicular to the set direction, for example, along the front-to-back direction as shown in Figure 5. Multiple channels 201 can simultaneously flow heat exchange medium, improving heat exchange efficiency. By adjusting the number of bends 22, the number of channels 201 formed and the size of the reinforcement 20 can be adjusted, improving the adaptability of the reinforcement 20.

[0110] Furthermore, the structure formed by the bent portion 22 and the connecting portion 21 has high compressive strength, which can better improve the structural strength of the battery cooling plate 100 . Furthermore, the molding process is simple, which is beneficial to reducing the production cost of the reinforcement 20 .

[0111] In the above embodiment, the forming method of the connecting portion 21 and the bending portion 22 is not limited. For example, they can be formed separately and then connected together by welding or the like, or they can be formed integrally by extrusion or the like.

[0112] In other embodiments, referring to Figures 10 and 11 , which are schematic structural diagrams of a reinforcement member 20 according to the second and third embodiments of the present application, the reinforcement member 20 includes an outer peripheral wall 23 and partition walls 24 . The partition walls 24 are disposed within the space enclosed by the outer peripheral wall 23 to divide the space enclosed by the outer peripheral wall 23 into a plurality of channels 201 .

[0113] The peripheral wall 23 includes a peripheral wall extending in a set direction to generally form a tubular or cylindrical structure. The partition wall 24 can be connected to the inner peripheral surface of the peripheral wall 23 to separate the space enclosed by the peripheral wall 23. As needed, the number of channels 201 formed and the structural strength of the reinforcement 20 itself can be adjusted by adjusting the number of partition walls 24. The more partition walls 24 there are, the higher the strength and the smaller the area of ​​the channel 201. The extension direction of the partition wall 24 is not limited. It can extend in the up and down direction as shown in Figure 10, or it can extend at an angle as shown in Figure 11; and the multiple partition walls 24 can be parallel to each other or non-parallel, can be spaced apart from each other, or can be connected to each other. For example, the multiple partition walls 24 shown in Figure 10 are parallel to each other and spaced apart, which makes the structure simpler. For example, the multiple partition walls 24 shown in Figure 11 extend at an angle so that two connected partition walls 24 are connected to form a zigzag shape, which has a better effect of improving the structural strength.

[0114] The reinforcement 20 formed by the outer peripheral wall 23 and the partition wall 24 has high compressive strength, is more effective in improving the structural strength of the battery cooling plate 100, and is simple to form, which is conducive to reducing the production cost of the reinforcement 20.

[0115] In some embodiments, the reinforcement 20 is in surface contact with the wall of the flow channel 101. Surface contact means that the contact area between the reinforcement 20 and the wall of the flow channel 101 is a surface, rather than point or line contact. The contact surface can be any shape, such as a flat surface or a curved surface.

[0116] By ensuring that the reinforcement 20 is in surface contact with the wall of the flow channel 101, on the one hand, the connection strength and support stability between the reinforcement 20 and the plate body 10 can be increased, thereby improving the strength of the battery cooling plate 100; on the other hand, the heat exchange between the reinforcement 20 and the plate body 10 can be enhanced, thereby improving the heat exchange efficiency.

[0117] For example, in some embodiments including the connecting portion 21, the connecting portion 21 may be a flat plate and in surface contact with the wall of the flow channel 101; in some embodiments including the peripheral wall 23, a portion of the outer surface of the peripheral wall 23 may be a plane and in surface contact with the wall of the flow channel 101.

[0118] In the embodiment of the present application, the reinforcement 20 may be a part made entirely of one material, or may be composed of a combination of multiple different materials.

[0119] In some embodiments where the reinforcement member 20 is disposed in the flow channel 101 , the reinforcement member 20 may be made of a corrosion-resistant material, or a corrosion-resistant material layer may be disposed on the surface of the reinforcement member 20 .

[0120] Corrosion-resistant materials include, but are not limited to, tri-series aluminum and hexa-series aluminum. In some embodiments, the base material of the reinforcement member 20 is made of iron or steel, and a corrosion-resistant material layer is provided on the surface of the base material. The surface of the reinforcement member 20 includes an outer surface and an inner surface of the channel 201.

[0121] Corrosion-resistant materials are not easy to react with heat exchange media. By making the entire reinforcement 20 of corrosion-resistant material or providing a corrosion-resistant material layer on the surface, the entire reinforcement 20 is not easy to react with the heat exchange medium or the exposed part is not easy to react with the heat exchange medium, which is beneficial to improving the service life of the reinforcement 20 and enhancing the structural stability of the battery cooling plate 100.

[0122] According to some embodiments of the present application, as shown in FIG. 7 to FIG. 11 , the reinforcement member 20 may include a first thinned region 25 , and the first thinned region 25 is connected to the wall surface of the flow channel 101 .

[0123] The first thinned area 25 , ie, the thickness of the reinforcement 20 in this area is less than the maximum thickness of the reinforcement 20 . The thickness refers to the dimension in a direction perpendicular to the wall of the flow channel 101 , such as the dimension in the up-down direction.

[0124] By forming the first thinned region 25 and connecting it to the wall of the flow channel 101, the reinforcement member 20 can be connected to the wall of the flow channel 101 through the region of smaller thickness, making the connection more convenient and secure. For example, in an embodiment where the reinforcement member 20 is welded to the plate body 10, the first thinned region 25 can increase the strength of the weld, thereby improving the reliability of the connection.

[0125] In addition, in some embodiments in which the reinforcement 20 has a channel 201, continuing to refer to Figures 7-11, the first thinning area 25 can be a notch groove 251 provided in the reinforcement 20, and the reinforcement 20 has channels 201 located on both sides of the notch groove 251, and the notch groove 251 connects the channels 201 on both sides.

[0126] The thickness of the reinforcement member 20 in the area where the notch groove 251 is located is reduced to form a first thinned region 25. For example, the notch groove 251 can be formed by cutting the reinforcement member 20, or the notch groove 251 can be formed simultaneously during the molding process. In the example shown in Figure 9, the bent portion 22 can be cut to form the notch groove 251, and the portion of the connecting portion 21 opposite the disconnected region is formed as the first thinned region 25. In the examples shown in Figures 10 and 11, the top wall of the peripheral wall 23, the two side walls of the peripheral wall 23, and the partition wall 24 can be cut to form the notch groove 251, and the portion of the bottom wall of the peripheral wall 23 opposite the disconnected region is formed as the first thinned region 25.

[0127] The notch groove 251 can allow the heat exchange medium to circulate and connect the channels 201 on both sides, so that the first thinned area 25 used for connecting with the plate body 10 will not interfere with the flow of the heat exchange medium, which is conducive to improving the heat exchange efficiency.

[0128] In some embodiments, as shown in Figures 12-14, Figure 12 is a schematic diagram of the structure of stacked reinforcement members 20 provided in an embodiment of the present application; Figure 13 is a schematic diagram of the structure of one reinforcement member 20 in Figure 12; and Figure 14 is an enlarged schematic diagram of the structure of the circled area C in Figure 13. There are multiple reinforcement members 20, at least two of which include a second thinned region 26, and the second thinned regions 26 of the two reinforcement members 20 are stacked.

[0129] The second thinned region 26 , ie, the overall height of the reinforcement 20 in this region, is smaller than the maximum height of the reinforcement 20 .

[0130] The second thinning regions 26 of the two reinforcements 20 are stacked, that is, the extension directions of the two reinforcements 20 intersect and the two reinforcements 20 overlap each other, so that the overall structural strength of the multiple reinforcements 20 is stronger, and the effect of improving the structural strength of the battery cooling plate 100 is better.

[0131] Furthermore, the stacked arrangement of the second thinned regions 26 can reduce the overall height of the overlapping regions of the two reinforcement members 20, making the overlapping regions more space-efficient and less likely to interfere with other structures. For example, in an embodiment where the reinforcement members 20 are disposed within the flow channel 101, the second thinned regions 26 can ensure that the height of the overlapping regions is equal to or close to the height of the unthinned regions of the reinforcement members 20, thereby accommodating the spatial limitations of the flow channel 101 and preventing the overlapping regions from blocking the flow channel 101.

[0132] In addition, in some embodiments where the reinforcement 20 has a channel 201, as shown in Figures 12-14, the channel 201 can be partially located in the second thinning area 26, so that the second thinning area 26 will not block the circulation of the heat exchange medium in the channel 201, and the heat exchange medium inside the reinforcement 20 flows smoothly.

[0133] For example, in some specific embodiments, as shown in Figures 12-14, the channel 201 may include a first section 103 and a second section 104, wherein the first section 103 is located in the second thinned region 26, and the second section 104 is connected to the first section 103. The flow area of ​​the second section 104 is greater than the flow area of ​​the first section 103.

[0134] As a result, the first section 103 has a smaller flow area to accommodate the smaller height of the second thinned region 26. The second section 104 has a larger flow area to better accommodate the larger height of the non-thinned region, thereby increasing the flow rate of the heat exchange medium and providing support and reinforcement for the plate body 10. Furthermore, the connection between the first section 103 and the second section 104 ensures a continuous channel 201 within the reinforcement member 20, unaffected by other overlapping reinforcement members 20 and ensuring smooth flow of the heat exchange medium within the reinforcement member 20.

[0135] In some specific embodiments, the second thinned region 26 can be formed by flattening the reinforcement member 20, thereby simultaneously forming the first section 103 with a smaller flow area. This simplifies the manufacturing process. Furthermore, the flattening process can form a small facet in the second thinned region 26, which can serve as a mating surface with the second thinned region 26 of another reinforcement member 20, thereby further stabilizing the connection between the two reinforcement members 20.

[0136] The chemical chamber 1000 of the vehicle body 2000 according to the second embodiment of the present application includes the battery cooling plate 100 of the above-described embodiment. Thus, by employing the above-described battery cooling plate 100, the strength of at least the region of the plate body 10 where the flow channel 101 is located is reinforced by the reinforcement 20, thereby improving the overall impact resistance of the battery cooling plate 100. This reduces the risk of plastic deformation in the region of the flow channel 101 on the battery cooling plate 100 and reduces the risk of collapse of the flow channel 101, thereby improving the stability of the thermal management function of the chemical chamber 1000.

[0137] According to the third aspect of the present application, the vehicle body 2000 includes the chemical chamber 1000 of the vehicle body 2000 according to the above-described embodiment of the present application. Thus, by using the above-described chemical chamber 1000 of the vehicle body 2000, the strength of at least the region of the plate body 10 where the flow channel 101 is located is reinforced by the reinforcement 20, thereby improving the overall impact resistance of the battery cooling plate 100. This reduces the risk of plastic deformation in the region of the battery cooling plate 100 where the flow channel 101 is located, and reduces the risk of collapse of the flow channel 101, thereby improving the stability of the thermal management function of the chemical chamber 1000.

[0138] In some embodiments, as shown in Figure 15 , the battery cooling plate 100 serves as the floor of the vehicle body 2000 . Thus, the battery cooling plate 100 not only manages thermal management within the chemical compartment 1000 but also serves as the passenger compartment floor. This reduces the number of components and space required for the vehicle 3000 , providing more space for the installation of battery cells within the chemical compartment 1000 , thereby improving energy density. Furthermore, by including a reinforcing member 20 to enhance strength, the battery cooling plate 100 is less susceptible to impacts such as footsteps or objects impacting the passenger compartment floor, potentially reducing or even eliminating its thermal management function. This improves the service life and user experience of the vehicle 3000 .

[0139] As shown in FIG15 , a vehicle 3000 according to a fourth embodiment of the present application includes a vehicle body 2000 according to the aforementioned embodiment of the present application. Thus, by employing the aforementioned vehicle body 2000, the strength of at least the region of the plate body 10 where the flow channel 101 is located is reinforced by the reinforcement 20, thereby improving the overall impact resistance of the battery cooling plate 100. This reduces the risk of plastic deformation in the region of the flow channel 101 on the battery cooling plate 100, and reduces the risk of collapse of the flow channel 101, thereby improving the stability of the thermal management function of the chemical chamber 1000.

[0140] Chemical chamber 1000 can be used to power vehicle 3000. For example, chemical chamber 1000 can serve as an operating power source for vehicle 3000. Vehicle 3000 may also include a controller and a motor. The controller is used to control chemical chamber 1000 to power the motor, for example, to meet the power requirements of vehicle 3000 during startup, navigation, and driving.

[0141] The following describes a battery cooling plate 100 , a chemical chamber 1000 having the battery cooling plate 100 , and a vehicle 3000 having the chemical chamber 1000 according to some specific embodiments of the present application with reference to the accompanying drawings.

[0142] As shown in Figures 1-15, vehicle 3000 includes a body 2000, which comprises an upper and lower body. The lower body comprises a front cabin assembly, a chemical compartment 1000, and a rear floor assembly. The upper cover of the chemical compartment 1000 serves as a battery cooling plate 100. The battery cells in the chemical compartment 1000 are arranged in an inverted arrangement, with the electrical connections facing downward. The battery cooling plate 100 is bonded to the heat dissipation surfaces of the battery cells. After the lower and upper bodies are assembled, the battery cooling plate 100 serves as the floor of the passenger compartment. Components such as the center console, front seats, and rear seat cushions can be located above the battery cooling plate 100. The area without components is the impact zone 102, which is prone to foot contact and heavy objects.

[0143] The battery cooling plate 100 includes a first plate body 11, a second plate body 12 and a plurality of reinforcement members 20. The first plate body 11 is a flow channel 101 plate having a flow channel 101 groove. The second plate body 12 is a heat dissipation plate and the majority of the plate is a large-area flat plate. The second plate body 12 and the first plate body 11 are stacked along the thickness direction to cover the notch of the flow channel 101 groove to form the flow channel 101.

[0144] The reinforcement member 20 is disposed within the flow channel 101, and its height is less than or equal to that of the flow channel 101. The reinforcement member 20 can be located within the flow channel 101 in the impacted region 102 to increase strength and prevent collapse of the flow channel 101, thereby preventing loss of thermal management functionality and reducing degradation of thermal management functionality. Of course, the reinforcement member 20 can also be located within the flow channel 101 opposite the low-temperature region of the chemical chamber 1000 to enhance heat exchange and alter the flow distribution of the heat exchange medium.

[0145] The plurality of reinforcement members 20 can be independent of each other or can be spliced ​​and combined to form a shape, and the overlapping combination methods include welding, clamping, riveting, etc. The reinforcement member 20 can be fixed by first securely fixing the reinforcement member 20 on the first plate 11 and then brazing the first plate 11 and the second plate 12; or the reinforcement member 20 can be first securely fixed on the second plate 12 and then brazing the first plate 11 and the second plate 12; or the reinforcement member 20, the first plate 11, and the second plate 12 can be pre-assembled and then brazed, and during the brazing process, at least one surface of the reinforcement member 20 is fused to the first plate 11 or the second plate 12 by flux. The reinforcement member 20 can be fixed by welding, bonding, clamping, etc. For example, the reinforcement 20 has a first thinned area 25 as a welding area to facilitate welding with the first plate 11 or the second plate 12, so that the reinforcement 20 is reliably fixed on the first plate 11 or the second plate 12 to prevent the reinforcement 20 from moving or flipping in the flow channel 101.

[0146] The two reinforcers 20 spliced ​​together may have a second thinned area 26 formed by a flattening process. The second thinned area 26 has a small plane that can serve as an overlap and welding plane for the second thinned areas 26 of the two reinforcers 20 .

[0147] The reinforcement member 20 can be formed by extrusion, bending, stamping, 3D printing, or other methods. Furthermore, the reinforcement member 20 can have a high compressive strength and be easily formed, such as the structure formed by the connection portion 21 and multiple bent portions 22 shown in Figure 9, or the structure formed by the peripheral wall 23 and multiple partition walls 24 shown in Figures 10-11. The high compressive strength can effectively prevent the flow channel 101 from collapsing, while the simple forming process can reduce the production cost of the reinforcement member 20.

[0148] The plurality of reinforcement members 20 may be made of the same material and all of them may be resistant to corrosion by the heat exchange medium, such as VI series aluminum; or may have a coating on the surface thereof that is resistant to corrosion by the heat exchange medium.

[0149] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0150] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
