Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to an energy storage liquid-cooled tray. Background Technology

[0002] In the field of battery technology, especially in energy storage battery systems, the liquid cooling tray serves as a core component for battery support and heat dissipation, and its performance directly affects the battery's operational stability and lifespan. In existing technologies, the liquid cooling tray typically consists of a mounting plate and a liquid guide plate. The battery is mounted on one side of the mounting plate, and the liquid guide plate and the other side of the mounting plate enclose a liquid flow space for coolant circulation. The flow of coolant removes the heat generated by the battery during operation. However, traditional liquid cooling trays typically employ a single-channel or simple parallel-channel structure for the liquid flow space. This single-path flow of the coolant can lead to uneven velocity distribution, causing coolant stagnation in certain areas (such as channel corners or areas far from the inlet). This results in insufficient heat dissipation for the battery on the mounting plate, leading to localized high temperatures. Furthermore, to ensure structural stability of the liquid flow space, the connection between the guide plate and the mounting plate often relies on edge fixation. Under the weight of the battery and external loads, relative deformation can easily occur between the two, potentially compressing the liquid flow space, affecting coolant circulation, and reducing the overall load-bearing capacity of the tray, thus impacting the safe operation of the battery system. Therefore, optimizing the liquid flow path of the liquid cooling tray to improve heat transfer uniformity and enhancing structural strength to ensure load-bearing stability have become pressing technical challenges in this field. Utility Model Content

[0003] To overcome the above-mentioned defects, embodiments of this utility model provide an energy storage liquid cooling tray, which solves the technical problem of uneven heat exchange caused by local coolant stagnation in related technologies.

[0004] According to one aspect, at least one embodiment of the present invention provides an energy storage liquid-cooled tray, comprising: Mounting plate, the aforementioned mounting plate is used to install the battery; A liquid guide plate is mounted on the mounting plate. The battery and the liquid guide plate are located on opposite sides of the mounting plate, and a liquid flow space is formed between the liquid guide plate and the mounting plate. The liquid guide plate has multiple recesses, the bottom wall of which abuts against the mounting plate. The multiple recesses are arranged in an array along the extension direction of the liquid flow space to make the liquid flow space appear as a mesh.

[0005] For example, in an energy storage liquid cooling tray provided by at least one embodiment of the present invention, at least two liquid flow spaces are formed between the liquid guide plate and the mounting plate. The liquid flow space includes a main cooling section and an auxiliary cooling section. There are multiple main cooling sections that are spaced apart. The auxiliary cooling section is used to connect the ends of the main cooling sections so that the multiple main cooling sections are connected in sequence. Each liquid flow space has a liquid inlet and a liquid outlet.

[0006] For example, in at least one embodiment of this utility model, an energy storage liquid cooling tray further includes: The liquid inlet pipe is located at the end of the liquid guide plate. The liquid inlet pipe is provided with at least two liquid inlet branches. Each liquid flow space is connected to one of the liquid inlet branches. The liquid inlet pipe, the liquid inlet branches and the liquid flow space are connected in sequence. The liquid outlet pipe is located at the end of the liquid guide plate and has at least two liquid outlet branches, with each of the liquid flow spaces connected to one of the liquid outlet branches.

[0007] For example, in an energy storage liquid cooling tray provided in at least one embodiment of the present invention, a settling section that fits the mounting plate is formed between two adjacent main cooling sections of the liquid guide plate.

[0008] For example, in an energy storage liquid cooling tray provided in at least one embodiment of the present invention, the mounting plate has a side baffle, the side baffle and the bottom wall of the mounting plate are integrally formed, and an installation space is formed between the side baffle and the bottom wall of the mounting plate, the installation space being used to accommodate a battery.

[0009] For example, in at least one embodiment of the present invention, an energy storage liquid cooling tray is provided, which further includes a support assembly disposed on the outer side wall of the side baffle. The support assembly includes a support portion and a reinforcing portion. The support portion is disposed on the outer side wall of the side baffle. The two ends of the reinforcing portion are respectively disposed on the liquid guiding plate and the side baffle. The end of the reinforcing portion near the support portion abuts against the support portion. The reinforcing portion covers the connection between the mounting plate and the side baffle to form a first support cavity. The side baffle, the support portion, and the reinforcing portion enclose each other to form a second support cavity.

[0010] For example, in at least one embodiment of the present invention, an energy storage liquid cooling tray is provided, which also includes an auxiliary plate. The auxiliary plate is provided at least once and is installed on the end face of the liquid guide plate away from the mounting plate. The auxiliary plate is used to strengthen the strength of the liquid guide plate. The auxiliary plate has an integrally formed groove and a support groove. The groove fits with the settling section, and the bottom wall of the support groove abuts against the end face of the liquid guide plate away from the mounting plate to form a third support cavity between the liquid guide plate and the auxiliary plate.

[0011] For example, in an energy storage liquid cooling tray provided in at least one embodiment of the present invention, the aforementioned reinforcing part is provided with a lifting hole.

[0012] For example, in an energy storage liquid cooling tray provided in at least one embodiment of the present invention, a fastening hole is provided at one end of the support portion away from the reinforcing portion. The fastening hole is used to pass through a fastener for connecting the sealing plate, and the sealing plate is used to close the installation space.

[0013] For example, in an energy storage liquid cooling tray provided in at least one embodiment of the present invention, the fastening hole is hexagonal, and the two opposite sidewalls of the fastening hole are parallel to the side baffle.

[0014] The beneficial effects of this utility model are as follows: In this invention, multiple recesses are provided on the liquid guide plate, with the bottom wall of each recess abutting against the mounting plate. These recesses are arrayed along the extension direction of the liquid flow space, creating a mesh-like structure. Firstly, the mesh-like liquid flow space allows the coolant to flow through multiple paths. The recesses guide the flow, reducing the accumulation of coolant on one side and ensuring a more uniform distribution of coolant along the width of the flow channel. This significantly increases the contact area between the coolant and the mounting plate, effectively improving heat exchange efficiency and ensuring that the heat generated during battery operation is promptly dissipated, preventing localized overheating that could affect battery performance and lifespan. Secondly, the abutting structure between the recesses and the mounting plate enhances the connection stability between the liquid guide plate and the mounting plate, improving the overall structural strength and load-bearing capacity of the tray. This better supports the battery mounted on the mounting plate, reducing tray deformation caused by battery weight or external forces and extending the tray's lifespan. Furthermore, this structural design, while ensuring good cooling performance and structural strength, eliminates the need for excessively complex components, facilitating a lightweight and compact tray design that meets the space and weight requirements of energy storage devices.

[0024] like Figures 1-3 and Figures 8-9As shown, an energy storage liquid-cooled tray according to one embodiment of the present invention is illustrated. The energy storage liquid-cooled tray is made entirely of stainless steel, and the components are securely connected by welding. The mounting plate 100 is flat, with the battery mounted on one side surface. A liquid guide plate 200 is fixed to the other side surface of the mounting plate 100 in a covering manner, with the edge of the liquid guide plate 200 connected to the edge of the mounting plate 100, forming a closed liquid flow space 300 between them. The side surface of the liquid guide plate 200 facing the mounting plate 100 has multiple recesses 210, which are recessed in a direction perpendicular to the surface of the mounting plate 100. The bottom wall of the recesses 210 contacts and is fixed to the surface of the mounting plate 100. The multiple recesses 210 are arranged in an array along the extension direction of the liquid flow space 300, forming channels for coolant flow between adjacent recesses 210. The arrangement of the multiple recesses 210 makes the liquid flow space 300 an interconnected mesh structure. For example, multiple rows of recesses 210 are spaced apart along the extension direction of the liquid flow space 300, with at least one recess 210 in each row, and the recesses 210 in adjacent rows are staggered along the extension direction of the liquid flow space 300. Figure 2 As shown, this allows the coolant to be evenly guided to both sides of the flow space and continue flowing forward when it flows between two adjacent recesses 210. During operation, the coolant flows in from the inlet of the flow space 300, flows along multiple channels of the mesh structure, flows through various areas of the mounting plate 100, and then flows out from the outlet.

[0025] The heat generated by the battery during operation is transferred to the mounting plate 100, which then transfers the heat to the side away from the battery. On one hand, the mounting plate 100 is in direct contact with the coolant in the liquid flow space 300, allowing heat to be transferred to the flowing coolant via the surface of the mounting plate 100. On the other hand, the mounting plate 100 is in contact with the bottom wall of the recess 210. After being transferred to the bottom wall of the recess 210, the heat diffuses along its sidewalls, which then contact the coolant in the liquid flow space 300, thus transferring heat to the coolant. Through these two pathways, the heat generated by the battery is absorbed by the coolant and carried out of the liquid flow space 300 by the flow of the coolant, achieving heat dissipation. In this structure, the contact between the recess 210 and the mounting plate 100 extends the connection point between the liquid guide plate 200 and the mounting plate 100 from the edge to the entire surface, reducing the relative deformation between them and preventing the liquid flow space 300 from being compressed due to deformation. Meanwhile, the mesh-like fluid flow space 300 allows the coolant to flow through multiple parallel channels, reducing the uneven flow velocity in a single channel, increasing the contact area between the coolant and the mounting plate 100, and improving the uniformity of heat exchange. The guide plate 200 is fixed to the mounting plate 100 using a welding process.

[0026] like Figures 4-9As shown, in this example, two independent liquid flow spaces 300 are provided between the liquid guide plate 200 and the mounting plate 100. Each liquid flow space 300 includes multiple main cooling sections 310 and multiple auxiliary cooling sections 320. The main cooling sections 310 extend parallel to the length of the mounting plate 100, and the multiple main cooling sections 310 are spaced apart along the width direction of the mounting plate 100. The auxiliary cooling sections 320 extend along the width direction of the mounting plate 100, and their two ends are respectively connected to the ends of adjacent main cooling sections 310, so that the multiple main cooling sections 310 are sequentially connected to form a continuous channel. One end of each liquid flow space 300 is a liquid flow inlet, and the other end is a liquid flow outlet. A liquid inlet pipe 400 is located at one end of the liquid guide plate 200. One end of the liquid inlet pipe 400 is connected to an external coolant source, and the other end branches to form two liquid inlet branches 410. Each liquid inlet branch 410 is connected to a liquid inlet of a liquid flow space 300. A liquid outlet pipe 500 is located at the other end of the liquid guide plate 200. One end of the liquid outlet pipe 500 is connected to an external recovery device, and the other end branches to form two liquid outlet branches 510. Each liquid outlet branch 510 is connected to a liquid outlet of a liquid flow space 300. On the liquid guide plate 200, the area between two adjacent main cooling sections 310 is recessed towards the mounting plate 100 to form a settling section 220. The surface of the settling section 220 is welded to the mounting plate 100.

[0027] Two independent fluid flow spaces 300 each receive coolant through a corresponding inlet branch 410. Within a single fluid flow space 300, the coolant flows along the channel formed by the main cooling section 310 and the auxiliary cooling section 320, exchanging heat only with the corresponding mounting plate 100 area, i.e., cooling only the batteries within that area. Because the number of batteries cooled by each fluid flow space 300 is reduced, the temperature rise of the coolant after absorbing heat from the corresponding battery area is limited to a smaller range. Compared to a single fluid flow space 300 needing to cool all batteries, resulting in a continuous rise in coolant temperature, this setup maintains a relatively low temperature within each independent space, resulting in a more stable temperature difference between the coolant and the batteries, thereby increasing the heat exchange rate per unit time and ensuring cooling quality. Simultaneously, the independent operation of the two fluid flow spaces 300 avoids the impact of abnormal heat generation in a particular battery area on the overall cooling effect, further improving the reliability of the cooling system.

[0028] The arrangement of multiple liquid flow spaces 300 enables coolant diversion, reduces the flow pressure within a single liquid flow space 300, and makes the flow velocity distribution more uniform. The combination of the main cooling section 310 and the auxiliary cooling section 320 creates a meandering liquid flow path, extending the flow time of the coolant within the liquid flow space 300 and increasing heat exchange efficiency. The settling section 220, through its contact with the mounting plate 100, further increases the connection points between the guide plate 200 and the mounting plate 100, improving structural stability.

[0029] The two side edges of the mounting plate 100 extend perpendicularly to its bottom wall to form side baffles 110. The side baffles 110 and the bottom wall of the mounting plate 100 are integrally formed, enclosing an installation space 120. The battery is placed in the installation space 120, and the side of the battery is in contact with the inner wall of the side baffles 110. A support assembly 600 is provided on the outer side wall of the side baffles 110. The support assembly 600 includes a reinforcing part 620 and a supporting part 610. The supporting part 610 is integrally formed with the side baffles 110 and is provided on the side baffles 110. The outer side wall of 10; the reinforcing part 620 is bent, and the two ends of the reinforcing part 620 are respectively welded to the liquid guide plate 200 and the side baffle 110. The end of the reinforcing part 620 near the supporting part 610 is welded to the supporting part 610. The reinforcing part 620 covers the connection between the mounting plate 100 and the side baffle 110. The reinforcing part 620, the mounting plate 100, the liquid guide plate 200, and the side baffle 110 form a first supporting cavity 630. The side baffle 110, the supporting part 610 and the reinforcing part 620 form a second supporting cavity 640.

[0030] The side baffle 110 and the mounting plate 100 are an integral structure, eliminating the connection gap between them. In traditional split structures, the connection between the side baffle 110 and the mounting plate 100 is prone to forming a channel for dust and moisture intrusion due to assembly gaps. However, the integral structure, through continuous molding, eliminates the splicing gaps at the transition between the side wall and the bottom wall of the installation space 120, structurally blocking the path of external dust entering the installation space 120 through gaps, and also reducing the condensation and penetration of moisture at the gaps.

[0031] Meanwhile, this integrated structure reduces the problem of gap expansion caused by long-term vibration and thermal expansion and contraction in the split connection, and can maintain the stability of the installation space 120 for a long time. The side baffle 110 and the mounting plate 100 are integrated structures, which reduces the number of positions in the installation space 120 that need to be sealed, enhances the sealing reliability of the installation space 120, reduces the chance of external humid air entering the installation space 120 and contacting the battery surface, reduces the risk of battery performance degradation or short circuit due to moisture, and thus improves the battery's operational stability in complex environments.

[0032] When the first support cavity 630 and the second support cavity 640 work together, they form a mutually supporting overall structure through the connection of the reinforcing part 620 and the supporting part 610. The first support cavity 630 utilizes the rigidity of the enclosed space to enhance the bending resistance of the connection between the mounting plate 100 and the side baffle 110; the second support cavity 640, through the enclosure of the side baffle 110, the supporting part 610, and the reinforcing part 620, enhances the shear resistance of the supporting part 610 in the direction perpendicular to the side baffle 110. The cooperation of the two cavities enriches the force distribution path of the support assembly 600. When external forces act on the side baffle 110 or the mounting plate 100, the forces can be transmitted to the walls of the two cavities through the reinforcing part 620 and the supporting part 610, and are jointly borne by the entire support assembly 600, avoiding overload of a single component, thereby improving the overall strength and deformation resistance of the support assembly 600.

[0033] An auxiliary plate 700 is provided on the side of the liquid guide plate 200 away from the mounting plate 100. Multiple auxiliary plates 700 are spaced apart along the length of the mounting plate 100. In this example, four auxiliary plates 700 are provided. The auxiliary plates 700 are installed on the end face of the liquid guide plate 200 away from the mounting plate 100 to enhance the strength of the liquid guide plate 200. A groove 710 and a support groove 720 are provided on the surface of the auxiliary plate 700 facing the liquid guide plate 200. The shape of the groove 710 matches the shape of the settling section 220, and the inner wall of the groove 710 fits against the outer wall of the settling section 220. The inner wall of the groove 710 and the outer wall of the settling section 220 are connected by welding. The support groove 720 is arranged in a direction perpendicular to the extension direction of the main cooling section 310. The bottom wall of the support groove 720 contacts the surface of the liquid guide plate 200 away from the mounting plate 100, forming a third support cavity 730 between the liquid guide plate 200 and the auxiliary plate 700. The edge of the auxiliary plate 700 is provided with multiple sunken parts that fit into the settling section 220. The sunken parts are connected to the settling section 220 by welding. The bottom wall of the support trough 720 is connected to the liquid guide plate 200 by welding.

[0034] The auxiliary plate 700 is positioned with the liquid guide plate 200 through the cooperation of the groove 710 with the settling section 220 and the cooperation of the sinking part with the settling section 220. The contact between the support groove 720 and the liquid guide plate 200 increases the support points of the auxiliary plate 700 for the liquid guide plate 200. The structure of the third support cavity 730 enhances the deformation resistance of the auxiliary plate 700 itself, thereby improving the overall strength of the liquid guide plate 200 and preventing the liquid guide plate 200 from bulging and deforming due to liquid flow pressure.

[0035] The surface of the reinforcing part 620 is provided with a lifting hole 621, which extends through both sides of the reinforcing part 620 in a direction perpendicular to the mounting plate 100. The mounting plate 100 has multiple fastening holes 130 at its edge away from the reinforcing part 620, extending through both sides along the thickness direction of the mounting plate 100. The sealing plate 800 is connected to the mounting plate 100 by fasteners passing through the fastening holes 130. The edge of the sealing plate 800 fits against the end of the side baffle 110, sealing the mounting space 120. The fastening hole 130 has a hexagonal structure, with its two opposite sidewalls parallel to the extending direction of the side baffle 110.

[0036] The lifting hole 621 provides a connection point for the entire pallet's handling, facilitating the movement of the pallet using lifting equipment. The sealing plate 800, connected to the mounting plate 100 via the fastening hole 130, encloses the battery within the mounting space 120, preventing external impurities from entering.

[0037] The support portion 610 has a fastening hole 130 at the end away from the reinforcing portion 620. The fastening hole 130 is hexagonal, with its two opposite sidewalls aligned with the extending direction of the side baffle 110. When a rivet nut is inserted into the fastening hole 130, the outer surface of the rivet nut can completely fit against the hexagonal hole wall, and the rivet nut and the support portion 610 are fixed together by the riveting process. Because the support portion 610 is relatively thin, it is not possible to directly machine threads on the inner wall of the fastening hole 130 to achieve a stable connection with the sealing plate 800. However, the introduction of the rivet nut provides an internal thread structure. When the sealing plate 800 is connected to the rivet nut by bolts, the threads of the bolts and the internal threads of the rivet nut engage tightly, avoiding the problem of insufficient thread strength caused by the thinness of the mounting plate 100. Meanwhile, the multiple sides of the hole wall form multi-directional constraints with the outer surface of the rivet nut, which disperses the force of the connection part, reduces the force in the width direction of the support part 610, matches the force direction of the overall structure of the mounting plate 100 and the side baffle 110, avoids shear stress at the edge of the hole wall, prevents the mounting plate 100 from cracking, and makes the connection between the mounting plate 100 and the sealing plate 800 tighter, ensuring the sealing of the installation space 120.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
