Description
TECHNICAL FIELD
[0001] The present specification relates to the technical field of power battery thermal management, and in particular to a manifold heat exchange structure, a battery structure and a vehicle. BACKGROUND
[0002] A large amount of heat is generated in the charging and discharging process of a power battery. If the heat cannot be dissipated in time and evenly, the temperature of the battery will rise, and the temperature distribution in the battery pack will be uneven (i.e., poor temperature field consistency). Excessive temperature will accelerate the chemical side reactions inside the battery, causing thermal runaway risk, which seriously threatens the safety of the vehicle. Uneven temperature will cause inconsistent decay rates of each single battery in the battery pack, and some batteries will be overcharged or overdischarged, thereby significantly reducing the overall energy efficiency, charging and discharging performance and cycle life of the battery pack. Therefore, efficient and uniform thermal management technology, especially cooling technology, has become the core and key of the design of a power battery system.
[0003] Among many thermal management technologies, liquid cooling technology has been widely used in medium and high power density power battery packs due to its high thermal conductivity, large specific heat capacity and high heat transfer capacity. At present, the most mainstream implementation scheme of liquid cooling technology is to use a brazed aluminum battery cold plate. The battery module is directly installed on the surface of the cold plate, the cooling liquid flows in the flow channel inside the cold plate, and the heat generated by the battery is conducted to the cold plate through a heat conducting medium (such as heat conducting glue), and then taken away by the cooling liquid.
[0004] In the prior art, the internal processing of the serpentine or S-shaped flow channel cold plate has a continuous bending single flow channel. After the cooling liquid flows into the inlet, it needs to flow through the entire surface of the cold plate in a meandering manner, and finally flows out of the outlet. Although this structure is simple and the manufacturing process is mature, it has the following inherent defects: when the cooling liquid flows in the long-distance, multi-bend serpentine flow channel, it will generate significant along-path resistance and local resistance, which will result in the need for higher pumping power to drive the circulation of the cooling liquid, thereby reducing the energy efficiency of the entire thermal management system; the temperature of the cooling liquid gradually rises from the inlet to the outlet of the flow channel (i.e., there is a significant temperature rise) during the flow process. This results in inconsistent temperatures in different regions of the cold plate surface, and the temperature of the battery installed in the inlet region of the cold plate is lower, while the temperature of the battery in the outlet region is higher, causing a huge temperature gradient inside the battery module. This temperature inconsistency will seriously deteriorate the working state of the battery pack, affecting its performance and life. SUMMARY
[0005] The present specification provides a manifold heat exchange structure to solve the problem of insufficient performance and short life of the battery pack caused by uneven temperature of the battery pack in the prior art.
[0006] The present specification adopts the following technical solutions: The present specification provides a manifold heat exchange structure, comprising a sealed shell, a heat exchange cavity is formed inside the sealed shell, a micro-channel heat exchange layer and a manifold dividing rib are arranged in the heat exchange cavity, the manifold dividing rib is stacked on the micro-channel heat exchange layer, the manifold dividing rib divides the heat exchange cavity into a front manifold distribution layer and a rear manifold convergence layer, the front manifold distribution layer and the rear manifold convergence layer are communicated through the micro-channel heat exchange layer; further comprising an upper pipe port assembly and a lower pipe port assembly, the upper pipe port assembly is communicated with the front manifold distribution layer, and the lower pipe port assembly is communicated with the rear manifold convergence layer.
[0007] According to the above technical means, the manifold dividing rib is used to divide the heat exchange cavity into a front manifold distribution layer and a rear manifold convergence layer, the front manifold distribution layer and the rear manifold convergence layer are communicated through the micro-channel heat exchange layer to form a cooling liquid / refrigerant flow channel, and when in use, the cooling liquid / refrigerant flowing out of the upper pipe port assembly quickly reaches and fills the front manifold distribution layer, uniformly cools the corresponding area of the front manifold distribution layer, and avoids excessive temperature difference in different areas; after the secondary flow of the front layer manifold distribution layer is uniformly distributed, the cooling liquid / refrigerant uniformly enters the rear manifold convergence layer through the micro-channel heat exchange layer, and the multiple flow uniform distribution can improve the uniformity of heat exchange, avoid local heat exchange shortage caused by uneven flow distribution, thereby reduce the temperature gradient inside the battery pack / module, and ensure the performance and service life.
[0008] Further, the micro-channel heat exchange layer comprises two or more micro-channel rib grooves arranged in parallel with each other, and each micro-channel rib groove is communicated with the front manifold distribution layer and the rear manifold convergence layer.
[0009] According to the above technical means, by arranging two or more micro-channel rib grooves arranged in parallel with each other, the main heat exchange area is divided into many independent micro flow channels, the heat exchange area of the cooling liquid / refrigerant is increased, a large heat exchange interface is provided for efficient heat transfer from the battery pack to the cooling liquid, and the overall heat exchange efficiency and heat dissipation capacity are improved; the cooling liquid / refrigerant can flow through each micro-channel rib groove synchronously, ensuring that the cooling effect can uniformly act on the entire battery pack; the parallel arrangement of multiple micro-channels is equivalent to dispersing the total flow into many small flow channels, so that the cooling liquid does not need to flow through a long and winding path, thereby greatly reducing the overall flow resistance of the system.
[0010] Further, both ends of each micro-channel rib groove are respectively in abutment with the inner side wall of the sealed shell.
[0011] Based on the above technical means, it is ensured that the coolant / refrigerant can flow from one side of the sealed housing to the other side, forming the shortest and most direct heat exchange path in the planar dimension. The coolant / refrigerant can pass through the entire heat exchange area at the fastest speed, which not only reduces its residence time in the flow channel and improves the thermal response speed and temperature uniformity, but also helps to ensure the sealing between the flow channels, improving the structural reliability and service life of the product.
[0012] Furthermore, each of the aforementioned microchannel ribs is formed by dividing it into two or more microchannel rib walls.
[0013] According to the above-mentioned technical means, each microchannel rib groove is composed of two or more microchannel rib walls, which can transfer the temperature of the coolant / refrigerant to the microchannel rib walls on both sides of each microchannel rib groove, thereby making the heat exchange area of the microchannel heat exchange layer large.
[0014] Furthermore, the two ends of the manifold dividing rib abut against the inner sidewall of the sealing housing.
[0015] Based on the above technical means, the front manifold distribution layer and the rear manifold converging layer are divided into two independent cavities, which prevents the coolant from "short-circuiting" between the upper and lower cavities and ensures that the coolant / refrigerant flows from the front manifold distribution layer, through the microchannel heat exchange layer, and then into the rear manifold converging layer.
[0016] Furthermore, the manifold dividing rib includes two or more sub-dividing ribs, each of which is connected end to end in sequence, and adjacent sub-dividing ribs are arranged in a "V" shape.
[0017] Based on the above technical means, the "V"-shaped arrangement forms a flow channel structure with guiding function in the manifold distribution layer, which can more effectively transport the fluid to the area far away from the inlet, maintain a low overall flow resistance, reduce the flow dead zone, and ensure that the coolant can uniformly cover the inlet section of the entire microchannel heat exchange layer, thus achieving uniform flow distribution of coolant / refrigerant.
[0018] Furthermore, the upper manifold assembly includes an upper main pipe and two or more upper branch pipes, each of the upper branch pipes being connected to the upper main pipe, and each of the upper branch pipes being disposed toward the front manifold distribution layer.
[0019] According to the above technical means, the coolant can flow through the upper branch pipe and the upper main pipe to the front manifold distribution layer. By setting multiple upper branch pipes, the coolant flows into the front manifold distribution layer through multiple upper branch pipes. This two-stage distribution mode of "first splitting, then distributing" avoids the problem of excessive local flow rate or uneven distribution that may be caused by single-point injection of coolant / refrigerant, and can evenly distribute the incoming coolant to the upper manifold distribution layer.
[0020] Furthermore, the lower manifold assembly includes a lower main pipe and two or more lower branch pipes, each of the lower branch pipes being connected to the lower main pipe and each of the lower branch pipes being disposed toward the rear manifold converging layer.
[0021] Based on the above technical means, by setting multiple lower branch pipes, it can be ensured that the coolant / refrigerant can enter the rear manifold converging layer evenly from the microchannel heat exchange layer and then flow out from the lower main pipe and lower branch pipes in a timely manner, preventing the coolant / refrigerant from accumulating in the rear manifold converging layer. This effectively avoids backflow obstruction caused by a single outlet or insufficient local heat exchange caused by local eddies, thus ensuring battery performance and lifespan.
[0022] Furthermore, a battery structure is also provided, including a battery pack and the aforementioned manifold heat exchange structure, wherein the battery pack is arranged on the manifold heat exchange structure, and the manifold heat exchange structure is used to exchange heat with the battery pack.
[0023] Furthermore, a vehicle is also provided, including a vehicle body and the aforementioned battery structure, wherein the battery structure is mounted on the vehicle body.
[0024] The above-mentioned technical solutions adopted in this specification can achieve the following beneficial effects: The coolant / refrigerant flowing out from the upper port assembly first reaches the front manifold distribution layer, and then enters the microchannel heat exchange layer to exchange heat with the battery pack / module. This ensures that the coolant / refrigerant covers the entire heat exchange area, avoiding insufficient local heat exchange caused by uneven flow distribution, thereby reducing the temperature gradient inside the battery pack / module and ensuring its performance and lifespan. Similarly, the rear manifold converging layer is connected to the microchannel heat exchange layer. The coolant / refrigerant flows from the microchannel heat exchange layer through the rear manifold converging layer and out from the lower port assembly, ensuring smooth flow of the coolant / refrigerant and preventing coolant / refrigerant from accumulating in the rear manifold converging layer.

[0034] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.
[0035] Example 1 like Figure 1 and Figure 2 As shown, this embodiment proposes a manifold heat exchange structure, including a sealed shell 1, with a heat exchange cavity (not shown in the figure) formed inside the sealed shell 1. The heat exchange cavity is provided with a microchannel heat exchange layer 2 and a manifold partition layer (not shown in the figure). The manifold partition layer is stacked on the microchannel heat exchange layer 2, and the manifold partition layer divides the heat exchange cavity into a front manifold distribution layer 11. Figure 3 The area enclosed by the dotted line) and the rear manifold converging layer 12 ( Figure 3 The area enclosed by the midpoint line) includes the front manifold distribution layer 11 and the rear manifold converging layer 12 connected by the microchannel heat exchange layer 2; it also includes an upper pipe port assembly 3 and a lower pipe port assembly 4, with the upper pipe port assembly 3 connected to the front manifold distribution layer 11 and the lower pipe port assembly 4 connected to the rear manifold converging layer 12.
[0036] like Figure 1 andFigure 2 As shown, in this embodiment, when cooling is required, the coolant / refrigerant (not shown in the figure) first flows out from the upper port assembly 3 and enters the front manifold distribution layer 11. Since the front manifold distribution layer 11 and the rear manifold converging layer 12 are connected through the microchannel heat exchange layer 2, the coolant / refrigerant flows from the front manifold distribution layer 11 through the microchannel heat exchange layer 2 and the rear manifold converging layer 12, and finally flows out from the rear manifold converging layer 12 through the lower port assembly 4.
[0037] In other embodiments, when heating is required, a coolant / refrigerant at a higher temperature (not shown in the figure) flows from the upper port assembly 3 into the front manifold distribution layer 11, passes through the front manifold distribution layer 11, the microchannel heat exchange layer 2 and the rear manifold converging layer 12 in sequence, and finally flows out from the rear manifold converging layer 12 through the lower port assembly 4.
[0038] In this preferred embodiment, the microchannel heat exchange layer 2, the front manifold distribution layer 11, and the rear manifold converging layer 12 can be integrally formed, such as by brazing, laser welding, and diffusion welding.
[0039] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the microchannel heat exchange layer 2 includes two or more microchannel ribs 21 arranged in parallel with each other, and each microchannel rib 21 is connected to the front manifold distribution layer 11 and the rear manifold converging layer 12 respectively.
[0040] In this preferred embodiment, the flow direction of the microchannel rib groove 21 is perpendicular to or at a certain angle to the distribution flow direction of the front manifold distribution layer 11.
[0041] In this embodiment, the dimensions of each microchannel rib 21 can be determined by computational fluid dynamics (CFD) simulation optimization, such as simulation software like COMSOL and ANSYS Fluent. The width of each microchannel rib 21 is preferably 2~4mm, and the material is preferably copper, aluminum, or aluminum alloy.
[0042] By setting two or more parallel microchannel fins 21, the main heat exchange area is divided into numerous independent micro-channels, increasing the heat exchange area of the coolant / refrigerant. This provides a larger heat exchange interface for the efficient transfer of heat from the battery pack 6 to the coolant / refrigerant, thereby improving the overall heat exchange efficiency and heat dissipation capacity. The coolant / refrigerant can flow synchronously through each microchannel fin 21, ensuring that the cooling effect can be uniformly applied to the entire battery pack 6. The parallel arrangement of multiple microchannel fins 21 is equivalent to dispersing the total flow rate into many small channels, so that the coolant / refrigerant does not need to flow through a long and tortuous path, thereby significantly reducing the overall flow resistance of the system.
[0043] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, both ends of each microchannel rib groove 21 abut against the inner sidewall of the sealing housing 1.
[0044] This ensures that the coolant / refrigerant can flow from one side of the sealed housing 1 to the other side, forming the shortest and most direct heat exchange path in the planar dimension. The coolant / refrigerant can pass through the entire heat exchange area at the fastest speed, which not only reduces its residence time in the flow channel, improves the thermal response speed, and improves temperature uniformity, but also helps to ensure the sealing between the flow channels, improving the structural reliability and service life of the product.
[0045] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, each microchannel groove 21 is divided by two or more microchannel rib walls 22. The division of each microchannel groove 21 by two or more microchannel rib walls 22 allows the temperature of the coolant / refrigerant to be transferred to the microchannel rib walls 22 on both sides of each microchannel groove 21, resulting in a large heat exchange area for the microchannel heat exchange layer 2.
[0046] In this embodiment, the height of each microchannel rib 22 is 3~5 mm, the wall thickness of each microchannel rib 22 is 1~2 mm, and the material of each microchannel rib 22 is preferably copper, aluminum or aluminum alloy.
[0047] like Figure 2 and Figure 3 As shown, in this embodiment, the manifold partition layer includes manifold partition ribs 5, with both ends of the manifold partition ribs abutting against the inner sidewall of the sealing housing 1. This divides the front manifold distribution layer 11 and the rear manifold converging layer 12 into two independent cavities, ensuring that the coolant / refrigerant flows along the path of the front manifold distribution layer 11, through the microchannel heat exchange layer 2, and then into the rear manifold converging layer 12.
[0048] likeFigure 2 and Figure 3 As shown, in this embodiment, the manifold dividing rib 5 includes two or more sub-dividing ribs 51, each sub-dividing rib 51 is connected end to end in sequence, and the adjacent sub-dividing ribs 51 are arranged in a "V" shape.
[0049] The “V”-shaped arrangement, with its ends connected, forms a flow channel structure with guiding function within the manifold distribution layer. This structure can more effectively deliver coolant / refrigerant to areas far from the inlet, maintaining low overall flow resistance, reducing dead zones, and ensuring that coolant / refrigerant can uniformly cover the entire inlet section of the microchannel heat exchange layer 2, thus achieving uniform flow distribution of coolant / refrigerant.
[0050] like Figure 4 As shown, in this embodiment, the upper pipe assembly 3 includes an upper main pipe 31 and two or more upper branch pipes 32. Each upper branch pipe 32 is connected to the upper main pipe 31, and each upper branch pipe 32 is arranged facing the front manifold distribution layer 11.
[0051] In this preferred embodiment, the diameter of the upper main pipe 31 is set according to the flow requirements of the vehicle's thermal management piping system, and can be 4~8 cm (for example, for a power battery pack 6 of about 100 kWh, the outer diameter of the upper main pipe 31 is preferably 6~8 cm to ensure sufficient coolant flow); the distance between two adjacent upper branch pipes 32 is 1~1.5 times that of the upper main pipe 31. For example, an upper branch pipe 32 is set every 5~8 cm on an upper main pipe 31 with a diameter of 6 cm, which is used to evenly distribute the incoming coolant / refrigerant to the front manifold distribution layer 11.
[0052] Coolant can flow through the upper branch pipe 32 and the upper main pipe 31 to the front manifold distribution layer 11. By setting multiple upper branch pipes 32, the coolant flows into the front manifold distribution layer 11 through multiple upper branch pipes 32. This two-stage distribution mode of "first splitting, then distributing" avoids the problem of excessive local flow rate or uneven distribution that may be caused by single-point injection of coolant / refrigerant, and can evenly distribute the incoming coolant / refrigerant to the front manifold distribution layer 11.
[0053] like Figure 6 As shown, in this embodiment, the lower pipe assembly 4 includes a lower main pipe 41 and two or more lower branch pipes 42. Each lower branch pipe 42 is connected to the lower main pipe 41, and each lower branch pipe 42 is arranged towards the rear manifold converging layer 12.
[0054] In this preferred embodiment, the structure of the lower pipe assembly 4 is similar to that of the upper pipe assembly 3. The diameter of the lower main pipe 41 is the same as that of the upper main pipe 31, and the distance between two adjacent lower branch pipes 42 on the lower main pipe 41 is the same as the distance between two adjacent upper branch pipes 32 on the upper main pipe 31.
[0055] By setting multiple lower branch pipes 42, it can be ensured that the coolant / refrigerant can enter the rear manifold converging layer 12 evenly from the microchannel heat exchange layer 2 and then flow out from the lower main pipe 41 and the lower branch pipes 42 in a timely manner, preventing the coolant / refrigerant from accumulating in the rear manifold converging layer 12. This effectively avoids backflow obstruction caused by a single outlet or insufficient local heat exchange caused by local eddies, thus ensuring its performance and lifespan.

[0057] like Figure 1 As shown, this embodiment also provides a battery structure, including a battery pack 6 and the aforementioned manifold heat exchange structure. The battery pack 6 is arranged on the manifold heat exchange structure, which is used to exchange heat with the battery pack 6.
[0058] Example 3 This embodiment is similar to Embodiment 1, and the same parts are described in Embodiment 1. The following description only focuses on the improved parts.
[0059] This embodiment also provides a vehicle, including a vehicle body and the aforementioned battery structure, wherein the battery structure is mounted on the vehicle body.

Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
