Description

Technical Field

[0001] This utility model relates to the field of battery box technology, and in particular to a new energy vehicle battery box with a cooling structure and the vehicle itself. Background Technology

[0002] With the deepening of the global energy transition and the "dual-carbon" strategy, the new energy vehicle industry is experiencing explosive growth. According to the International Energy Agency, the global electric vehicle fleet will exceed 300 million vehicles by 2030, posing unprecedented challenges to the safety, reliability, and environmental adaptability of power battery systems. Under continuous high-speed driving, fast charging, and complex operating conditions, the temperature field uniformity inside the battery pack directly affects energy density, cycle life, and safety margins.

[0003] Traditional liquid cooling systems suffer from heat dissipation lag when dealing with intense charging and discharging conditions, resulting in temperature differences between battery cells exceeding 15°C. This severely impacts the overall efficiency of the battery pack, and these issues significantly hinder breakthroughs in new energy vehicles towards longer driving ranges and faster refueling efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new energy vehicle battery box with a cooling structure and a vehicle. The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A new energy vehicle battery box with a cooling structure includes a water-cooled plate, a frame beam is fixedly provided around the periphery of the water-cooled plate, a water-cooled plate coolant circulation channel is provided inside the water-cooled plate, and an inlet connector and an outlet connector connected to the water-cooled plate coolant circulation channel are fixedly provided on the side of the water-cooled plate; a plurality of circular cooling column mechanisms are uniformly arranged along the extension direction of the water-cooled plate coolant circulation channel.

[0005] The beneficial effects of this utility model are: the heat generated by the battery module during operation is transferred to the coolant in the cooling fluid circulation channel of the water-cooled plate through the liquid cooling plate. The arrangement of the circular cooling column mechanism in the cooling fluid circulation channel of the water-cooled plate can effectively increase the heat exchange area of ​​the coolant and accelerate the cooling, thereby effectively increasing the heat exchange efficiency of the water-cooled plate.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the circular cooling column mechanism includes a circular diversion column, with arc-shaped heat sinks fixed on both sides of the circular diversion column. The circular diversion column is located inside the two arc-shaped heat sinks, and coolant inlets and outlets are spaced apart between the two ends of the two arc-shaped heat sinks. The two coolant inlets and outlets are spaced apart along the extension direction of the coolant circulation channel of the water-cooled plate.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the circular diversion column is located at the center of the entire structure, and the arc-shaped heat sinks are symmetrically distributed on both sides of the diversion. The design of the circular diversion column can reduce the impact force of the coolant entering the circular cooling column mechanism at the moment, and the setting of the arc-shaped heat sinks can effectively increase the heat exchange area of ​​the coolant and accelerate the cooling.

[0009] Furthermore, a wave-shaped heat sink is fixedly provided on the inner side of the arc-shaped heat sink.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the setting of the wave-shaped heat sink can increase the heat exchange area of ​​the heat sink and the flow rate loss of the coolant is low when it passes through.

[0011] Furthermore, a central longitudinal beam is fixedly provided on the upper surface of the water-cooled plate, and a longitudinal beam coolant circulation channel is provided inside the central longitudinal beam. The two ends of the longitudinal beam coolant circulation channel are respectively connected to the water inlet connector and the water outlet connector.

[0012] The beneficial effect of adopting the above-mentioned further solution is that a coolant circulation channel is set inside the middle longitudinal beam. Cooling water enters the coolant circulation channel from the inlet joint and then flows out from the outlet joint to circulate the cooling water, thereby increasing the heat dissipation capacity of the middle area of ​​the box.

[0013] Furthermore, the longitudinal beam coolant circulation channel includes cooling pipes that abut against the two side walls of the central longitudinal beam, one end of each cooling pipe is connected to the inlet connector and the outlet connector, and the other ends of the two cooling pipes are connected to each other through a connecting channel.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the cooling pipes abut against the two side walls of the central longitudinal beam, which can quickly realize the rapid exchange of heat in the box and improve the heat dissipation efficiency.

[0015] Furthermore, the frame beam includes a left longitudinal beam, a right longitudinal beam, a front crossbeam, and a rear crossbeam. The left and right longitudinal beams are arranged in parallel, as are the front and rear crossbeams. The left, front, right, and rear crossbeams are connected end to end in sequence. All the left, right, front, and rear crossbeams are fixedly connected to the upper surface of the water-cooled plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the split-type frame beam facilitates the installation and disassembly of the frame beam.

[0017] Furthermore, the left longitudinal beam and the right longitudinal beam of the frame are provided with an inner cavity, and a honeycomb structure is provided in the inner cavity, and a heat insulation filler is provided in the honeycomb structure.

[0018] The beneficial effects of adopting the above-mentioned further solutions are as follows: the left and right longitudinal beams of the frame may be subjected to external lateral impacts. By setting a honeycomb structure in the inner cavity, the impact received by the left and right longitudinal beams of the frame during the collision process can be reduced, the impact of external impacts on the box can be reduced, and the risk of explosion of the battery module after being impacted can be avoided. Filling the honeycomb structure with heat insulation filler can further improve the impact resistance of the frame. Moreover, since the heat insulation filler has good heat insulation ability, it can effectively isolate the box from the external temperature and avoid the box being affected by the external temperature.

[0019] Furthermore, the inner cavity is divided into multiple sub-cavities by multiple partition plates extending to both ends of the inner cavity, and the honeycomb structure is disposed within the sub-cavities.

[0020] The beneficial effect of adopting the above-mentioned further solution is that it further improves the strength of the left and right longitudinal beams of the frame.

[0021] Furthermore, there are multiple honeycomb structures, and these multiple honeycomb structures are spaced apart along the length of the inner cavity.

[0022] The beneficial effects of adopting the above-mentioned further solutions are: the interval setting can improve the strength of the left and right longitudinal beams of the entire frame while reducing material usage and lowering costs.

[0023] This utility model solves the above-mentioned technical problems and also provides a car, including the new energy vehicle battery box with a cooling structure as described above.

[0024] The beneficial effects of adopting the above scheme are: the heat generated by the battery module during operation is transferred to the coolant in the cooling fluid circulation channel of the water-cooled plate through the liquid cooling plate. Arranging a circular cooling column mechanism in the cooling fluid circulation channel of the water-cooled plate can effectively increase the heat exchange area of ​​the coolant and accelerate the cooling, thereby effectively increasing the heat exchange efficiency of the water-cooled plate.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] Example 1 like Figures 1 to 8 As shown in the figure, this embodiment discloses a new energy vehicle battery box with a cooling structure, including a water-cooled plate 1. A frame beam is fixedly provided around the periphery of the water-cooled plate 1. A water-cooled plate coolant circulation channel 101 is provided inside the water-cooled plate 1. An inlet connector 102 and an outlet connector 103 communicating with the water-cooled plate coolant circulation channel 101 are fixedly provided on the side of the water-cooled plate 1. A plurality of circular cooling column mechanisms 2 are uniformly arranged along its extension direction inside the water-cooled plate coolant circulation channel 101.

[0028] In this embodiment, the water-cooled plate 1 includes a water-cooled base plate 104 and a water-cooled cover plate 105. The frame beam is fixedly disposed on the upper surface of the water-cooled cover plate 105. The middle part of the water-cooled base plate 104 is recessed downward to form the water-cooled plate coolant circulation channel 101. The flow extension direction of the water-cooled plate coolant circulation channel 101 can be set according to the corresponding heat dissipation requirements. For example, the volume of the water-cooled plate coolant circulation channel 101 below the battery module with a large heat generation is larger so as to accommodate more coolant, thereby increasing the heat exchange area and accelerating cooling.

[0029] The upper surface of the water-cooled base plate 104 is provided with a receiving groove for accommodating the water-cooled cover plate 105. The water-cooled cover plate 105 is disposed in the receiving groove, and the periphery of the water-cooled cover plate 105 is sealed against the periphery of the receiving groove to prevent coolant from flowing out from the gap between the water-cooled cover plate 105 and the water-cooled base plate 104, causing coolant loss or even short circuit of the battery module. To improve the sealing performance between the water-cooled cover plate 105 and the water-cooled base plate 104, a sealing gasket can be provided between the periphery of the water-cooled cover plate 105 and the periphery of the receiving groove.

[0030] like Figure 3 As shown, to facilitate the connection between the water-cooled plate 1 and the frame beam, the water-cooled base plate 104 is provided with multiple connection holes around its perimeter. The frame beam is fixedly connected to the water-cooled base plate 104 by bolts passing through the connection holes. When the frame beam is fixedly connected to the water-cooled base plate 104, the bottom end of the frame beam abuts against the upper surface of the perimeter of the water-cooled cover plate 105, pressing and fixing the water-cooled cover plate 105 onto the water-cooled base plate 104, thereby achieving a fixed connection between the frame beam, the water-cooled cover plate 105, and the water-cooled base plate 104, while ensuring the sealing of the water-cooled cover plate 105 and the water-cooled base plate 104.

[0031] To facilitate the fixed connection between the water-cooled plate 1 and the vehicle body, a plurality of connecting plates 106 are evenly fixed around the periphery of the water-cooled base plate 104, and the connecting plates 106 are provided with through holes for fixed connection with the vehicle body.

[0032] like Figure 4 As shown, in this embodiment, the circular cooling column mechanism 2 includes a circular diversion column 201. Arc-shaped heat sinks 202 are fixedly arranged on both sides of the circular diversion column 201. The circular diversion column 201 is located inside the two arc-shaped heat sinks 202. Coolant inlets and outlets 203 are spaced apart between the two ends of the two arc-shaped heat sinks 202. The two coolant inlets and outlets 203 are spaced apart along the extension direction of the coolant circulation channel 101 of the water-cooled plate. A wave-shaped heat sink 204 is fixedly arranged on the inner side of the arc-shaped heat sink 202. The circular diversion column 201 is located at the center of the entire structure, and the arc-shaped heat sinks 202 are symmetrically distributed on both sides of the diversion. The design of the circular diversion column 201 can reduce the impact force of the coolant entering the circular cooling column mechanism 2 at the moment of entry. The arrangement of the arc-shaped heat sinks 202 can effectively increase the heat exchange area of ​​the coolant and accelerate cooling. The arrangement of the wave-shaped heat sink 204 can increase the heat exchange area of ​​the heat sink and reduce the flow rate loss of the coolant when passing through.

[0033] The bottom ends of the circular diversion column 201 and the arc-shaped heat sink 202 are welded and fixed to the water-cooled base plate 104. To reduce weight, the middle part of the circular diversion column 201 is hollow.

[0034] Multiple circular cooling column mechanisms 2 are arranged on the water-cooled base plate 104, which can effectively increase the heat exchange efficiency of the water-cooled plate 1. At the same time, the design of the circular diversion column 201 and the arc-shaped heat sink 202 can save material usage when used on the cylindrical battery. Compared with other shapes, the arc-shaped surface of the circular diversion column 201 can effectively reduce the impact of the coolant on the column.

[0035] like Figure 1 As shown, specifically, the frame beam includes a left longitudinal beam 4, a right longitudinal beam 5, a front crossbeam 6, and a rear crossbeam 7. The left longitudinal beam 4 and the right longitudinal beam 5 are arranged in parallel, and the front crossbeam 6 and the rear crossbeam 7 are arranged in parallel. The left longitudinal beam 4, the front crossbeam 6, the right longitudinal beam 5, and the rear crossbeam 7 are connected end-to-end in sequence. All three beams are fixedly connected to the upper surface of the water-cooled plate 1. The split-type frame beam facilitates installation and disassembly.

[0036] A central longitudinal beam 3 and a plurality of spaced-apart supporting crossbeams 12 are fixedly provided on the upper surface of the water-cooled cover plate 105. The supporting crossbeams 12 are arranged parallel to the front crossbeam 6 and the rear crossbeam 7 of the frame. The middle of the plurality of supporting crossbeams 12 is provided with a mounting groove for installing the central longitudinal beam 3. One end of the central longitudinal beam 3 abuts against the side of the supporting crossbeam 12 near the rear crossbeam 7 of the frame. The middle of the front crossbeam 6 of the frame is provided with a clearance hole 11 for the central longitudinal beam 3 to pass through. The other end of the central longitudinal beam 3 passes through and extends out of the clearance hole 11, and is connected to the water inlet connector 102 and the water outlet connector 103 fixed on the water-cooled cover plate 105 through a coolant distribution pipe.

[0037] In an embodiment of this utility model, a plurality of connecting seats 13 are fixedly provided on the upper part of the supporting beam 12, and the connecting seats 13 are provided with connecting screw holes to facilitate the installation of the box cover and the fixing of the box cover.

[0038] The central longitudinal beam 3 is provided with a longitudinal beam coolant circulation channel. The two ends of the longitudinal beam coolant circulation channel are respectively connected to the water inlet connector 102 and the water outlet connector 103. The cooling water enters the longitudinal beam coolant circulation channel from the water inlet connector 102 and then flows out from the water outlet connector 103 to circulate the cooling water and increase the heat dissipation capacity of the central area of ​​the box.

[0039] Specifically, the longitudinal beam coolant circulation channel includes cooling pipes 301 that abut against the two side walls of the central longitudinal beam 3. One end of each cooling pipe 301 is connected to the inlet connector 102 and the outlet connector 103, respectively, and the other ends of the two cooling pipes 301 are connected to each other through a connecting channel 302. The abutment of the cooling pipes 301 against the two side walls of the central longitudinal beam 3 enables rapid heat exchange within the casing, improving heat dissipation efficiency.

[0040] like Figure 5 As shown, in this embodiment, the central longitudinal beam 3 is a profile, and the cooling pipe 301 and the central longitudinal beam 3 are an integral structure. For ease of processing, both ends of the central longitudinal beam 3 are through-type structures. To prevent coolant from flowing out from the end of the cooling pipe 301 and causing coolant loss, a plug 304 for sealing the end of the cooling pipe 301 is provided on the end away from the inlet connector 102 and the outlet connector 103. The ends of the two cooling pipes 301 away from the inlet connector 102 and the outlet connector 103 are connected by the connecting channel 302. During installation, the end of the central longitudinal beam 3 with the plug 304 abuts against the side of the supporting beam 12 to prevent the plug 304 from falling off under the hydraulic pressure of the coolant, thus improving safety. One end of the central longitudinal beam 3 that connects the water inlet connector 102 and the water outlet connector 103 is provided with a block 303 that covers the entire end face of the central longitudinal beam 3, and the block 303 is provided with a connection port. The two connection ports are respectively connected to two cooling pipes 301 so as to connect with the water inlet connector 102 and the water outlet connector 103 through the coolant distribution pipe.

[0041] like Figure 6 , Figure 7 , Figure 8 As shown, the left longitudinal beam 4 and the right longitudinal beam 5 of the frame are provided with an inner cavity, and a honeycomb structure 10 is provided in the inner cavity. The honeycomb structure 10 is filled with heat insulation material. The left longitudinal beam 4 and the right longitudinal beam 5 of the frame may be subjected to external lateral impacts. By providing the honeycomb structure 10 in the inner cavity, the impact received by the left longitudinal beam 4 and the right longitudinal beam 5 during the collision process can be reduced, the impact of external impacts on the box can be reduced, and the risk of explosion of the battery module after being impacted can be avoided. Filling the honeycomb structure 10 with heat insulation material can further improve the impact resistance of the frame. Moreover, since the heat insulation material has good heat insulation ability, it can effectively isolate the box from the external temperature and prevent the box from being affected by the external temperature.

[0042] In this embodiment, the heat insulation filler can be selected from aerogel, foam EPS, or foamed polypropylene.

[0043] The inner cavity is divided into multiple sub-cavities 9 by multiple partition plates 8 extending to both ends of the inner cavity. The honeycomb structure 10 is disposed within each sub-cavity 9, further improving the strength of the left longitudinal beam 4 and the right longitudinal beam 5 of the frame. Both the left longitudinal beam 4 and the right longitudinal beam 5 of the frame are profiles, and the partition plates 8 are integrally formed with the inner wall of the inner cavity.

[0044] The number of honeycomb structures 10 is multiple, and the multiple honeycomb structures 10 are spaced apart along the length direction of the inner cavity. The spaced arrangement can improve the strength of the left longitudinal beam 4 and the right longitudinal beam 5 of the entire frame while reducing material usage and lowering costs.

[0045] This invention employs three battery housing cooling structures, integrated into a single battery housing. Each of the three structural strategies can operate independently without interfering with the others. The parallel operation of these three strategies effectively increases the cooling capacity of the battery housing, thereby significantly improving battery range. Furthermore, the design of the left longitudinal beam 4 and right longitudinal beam 5 of the frame effectively enhances resistance to lateral impacts, reducing the risk of battery spontaneous combustion in collision accidents.

[0046] Example 2 This embodiment discloses a vehicle, including the new energy vehicle battery box with a cooling structure as described above.

[0047] In this invention, the heat generated during the operation of the battery module is transferred to the coolant in the cooling fluid circulation channel 101 of the water-cooled plate via the liquid cooling plate. The circular cooling column mechanism 2 arranged in the cooling fluid circulation channel 101 of the water-cooled plate can effectively increase the heat exchange area of ​​the coolant and accelerate the cooling, thereby effectively increasing the heat exchange efficiency of the water-cooled plate 1.
