Description

Technical Field

[0001] The present invention relates to the technical field of thermal management of energy storage batteries, and in particular to a thermal management structure of an energy storage battery module and an energy storage battery module structure. Background Art

[0002] At present, with the advancement of science and technology and the need for development, energy demand has increased, and the energy storage industry has risen accordingly. Lithium-ion battery energy storage has become the main electrochemical energy storage method due to its advantages such as high energy density, long cycle life, and low operation and maintenance costs. In the working conditions of lithium-ion batteries, temperature has an important impact on the decay rate of battery capacity, cycle life, and economic safety. Therefore, the use of efficient thermal management technology is conducive to increasing the working rate, extending the cycle life, reducing costs, and improving safety performance. At present, the traditional air cooling technology can no longer meet the growing heat dissipation needs of lithium-ion battery energy storage. Therefore, a major challenge in the development of lithium-ion battery energy storage is to optimize and update the traditional cooling technology and develop a more efficient thermal management technology solution.

[0003] Liquid cooling technology uses the heat exchange method of heat conduction and convection to exchange heat with the battery, thereby taking away the heat. Its cooling efficiency can be more than ten times higher than that of air cooling technology, and it has become an important development direction for thermal management of energy storage systems. Liquid cooling plates and immersion liquid cooling are the most commonly used liquid cooling technologies in energy storage battery systems. At present, both liquid cooling technologies are relatively mature. In comparison, immersion liquid cooling technology has better cooling effect and higher safety, but its fluid and manufacturing costs are higher, the required pumping power is greater, and the volume and weight are also larger. The cooling effect of the liquid cooling plate is not as good as that of the immersion type, but the cost is lower and it is easy to maintain, so it is favored. In order to further improve the cooling performance of the liquid cooling plate, the researchers designed its flow channel structure differently to enhance heat transfer.

[0004] Among the liquid cooling plate flow channel structures, the serpentine and meandering flow channel structures have a larger heat exchange area and a simpler structure, and therefore have been widely studied. In the prior art, some studies have proposed to arrange multiple liquid cooling flow channels in partitions on the liquid cooling plate, and each flow channel is looped into a cooling area, thereby forming multiple cooling areas. This structure can cool the heat source in a targeted manner and be adjusted to reduce the temperature difference of the battery pack. However, this structure is complicated, and the heat exchange area per unit volume has not increased, so the overall heat exchange effect is not significantly improved; secondly, if one of the flow channels is blocked or damaged, it will inevitably destroy the temperature balance of the battery module.

[0005] Therefore, it is necessary to develop a new thermal management structure for battery modules with high cooling efficiency, simple structure and excellent temperature uniformity, which is of great significance and value for maintaining low cell temperature, reducing the overall temperature of the battery pack, extending the battery cycle life, improving the working energy efficiency of the battery management system, and reducing economic investment.

[0006] Therefore, the inventor, relying on many years of experience and practice in related industries, proposes a thermal management structure of an energy storage battery module and an energy storage battery module structure to overcome the defects of the prior art. Summary of the invention

[0038] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0039] The specific embodiments of the present invention described herein are only used to explain the purpose of the present invention and cannot be understood as limiting the present invention in any way.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] like Figures 1 to 4As shown, the present invention provides a thermal management structure of an energy storage battery module, comprising: an integrated triangular channel heat exchanger structure 2 arranged at the bottom of the energy storage battery module 1, the integrated triangular channel heat exchanger structure 2 comprising a plurality of parallel heat exchange channels 21, the cross-section of the heat exchange channel 21 is arranged in a triangular shape, and the coolant flowing through the heat exchange channel 21 can directly contact the bottom of the energy storage battery module 1 for heat exchange; a vertically arranged inlet structure 23 and an outlet structure 24 are respectively provided on both sides of the integrated triangular channel heat exchanger structure.

[0042] The existing battery module liquid cooling plate mainly focuses on the design of the flow path in the liquid cooling plate. It has two disadvantages: first, the serpentine flow path basically maximizes the heat exchange area, and changing the flow path structure has little effect on increasing the heat exchange area per unit volume, so it is very difficult to improve the cooling capacity by changing the flow path structure; second, the flow path structure of the liquid cooling plate is relatively complex, and the pipeline path through which the coolant flows is relatively long, which reduces the fluidity and increases the total pressure drop of the heat exchanger.

[0043] In liquid cooling technology, the channel size of the microchannel heat exchanger is very small. Because the heat exchange area per unit volume is increased, it has efficient cooling capacity and has become an excellent cooling technology for microelectronic devices. Based on the above principle, the battery module is dozens of times larger than the size of microelectronic devices. The integrated triangular channel heat exchanger structure 2 of the present invention can also produce an equivalent cooling effect using relatively micro channels.

[0044] In the present invention, the integrated triangular channel heat exchanger structure is embedded in the bottom of the energy storage battery module, and the coolant flowing through the heat exchange channel can directly contact the bottom of the energy storage battery module for heat exchange, thereby realizing efficient heat dissipation of the battery module; the cross section of the heat exchange channel is triangular, and the triangular channel is small in size, so that the heat exchange area per unit volume of the heat exchanger is large, and the oblique ribs of the triangular channel have a larger heat dissipation area than conventional straight channels, further improving the heat exchange capacity; the coolant of the heat exchanger enters and exits through the vertically arranged inlet and outlet structures, respectively, which improves the coolant's fluidity and distribution uniformity, and improves the utilization rate of space resources. The present invention can strengthen the cooling of energy storage battery modules, improve cooling efficiency, reduce the weight and volume of the battery system, and reduce energy consumption.

[0045] Further, if Figure 1 , Figure 3 As shown, the integrated triangular channel heat exchanger structure 2 includes at least two heat exchangers, each heat exchanger includes a plurality of heat exchange channels 21, and each heat exchanger is provided with a vertically arranged inlet structure 23 at the first end of the heat exchange channel 21, and each heat exchanger is provided with a vertically arranged outlet structure 24 at the second end of the heat exchange channel 21.

[0046] At least two heat exchangers are arranged in parallel as an integrated unit. Compared with a single heat exchanger, the advantage is that there are at least two pairs of inlets and outlets, which not only improves the fluidity of the coolant and reduces the pumping power, but also facilitates the uniform distribution of the coolant in the channel.

[0047] Further, if Figure 1 , Figure 3 As shown, the heat exchanger includes a heat exchanger bottom plate 22, a plurality of heat exchange channels 21 are arranged on the heat exchanger bottom plate 22, an inlet structure 23 is arranged on the heat exchanger bottom plate 22 at the coolant inflow end of the heat exchange channel 21, an outlet structure 24 is arranged on the heat exchanger bottom plate 22 at the coolant outflow end of the heat exchange channel 21, and heat exchanger side plates 25 are arranged on the heat exchanger bottom plate 22 at both ends of the inlet structure 23 and the outlet structure 24;

[0048] The heat exchanger bottom plate 22, the inlet structure 23, the outlet structure 24 and the two heat exchanger side plates 25 enclose a heat exchange chamber with an opening at the top, and the top of the heat exchange channel 21 is abutted against the bottom of the energy storage battery module 1;

[0049] A side of the inlet structure close to the heat exchange channel, a side of the outlet structure close to the heat exchange channel and two heat exchanger side plates are sealed and connected to the bottom of the energy storage battery module.

[0050] Further, if Figure 1 , Figure 3 As shown, the integrated triangular channel heat exchanger structure 2 includes a plurality of heat exchangers, and adjacent sides of two adjacent heat exchangers share a heat exchanger side plate 25 .

[0051] In a specific embodiment, the integrated triangular channel heat exchanger structure is composed of two heat exchangers in parallel, and the fitting parts share a heat exchanger side plate 25. The integrated triangular channel heat exchanger structure is integrated at the bottom of the energy storage battery module 1. The heat exchanger has no top plate, and the internal coolant can directly contact the bottom plate of the energy storage battery module 1 to efficiently cool it, using less space resources to achieve a larger heat exchange area, reduce thermal resistance, and improve cooling effect. Two heat exchangers with vertical inlets and outlets are arranged in parallel as one body and integrated at the bottom of the energy storage battery module 1 to achieve efficient cooling. The integrated triangular channel heat exchanger structure has two pairs of inlet and outlet pipes, which improve the fluidity of the coolant compared to a pair of inlets and outlets of a single heat exchanger, and also improve the flow distribution uniformity of the coolant, thereby improving space utilization.

[0052] Further, if Figure 1 , Figure 3As shown, the inlet structure 23 and the coolant inlet end of the heat exchange channel 21 are spaced apart to form an inlet transition space 233; the inlet structure 23 includes an inlet end plate 232 extending upward from the heat exchanger bottom plate 22, and the inlet end plate 232 is sealedly connected to the bottom of the energy storage battery module 1 on one side close to the heat exchange channel, and an inlet connected to the inlet transition space is arranged on the inlet end plate 232, and the inlet is connected to a vertical inlet pipeline 231 extending upward, and the top end of the vertical inlet pipeline 231 is exposed to the energy storage battery module 1.

[0053] Further, if Figure 1 , Figure 3 As shown, the outlet structure 24 and the coolant outflow end of the heat exchange channel 21 are spaced apart to form an outflow transition space 243, and the outlet structure 24 includes an outflow end plate 242 extending upward from the heat exchanger bottom plate 22, and the outflow end plate 242 is sealedly connected to the bottom of the energy storage battery module 1 on one side close to the heat exchange channel 21, and an outlet connected to the outflow transition space 243 is arranged on the outflow end plate 242, and the outflow is connected to a vertical outlet pipeline 241 extending upward, and the top end of the vertical outlet pipeline 241 is exposed to the energy storage battery module 1.

[0054] Furthermore, the inlet and the vertical inlet pipeline are arranged in the middle position of the inlet end plate 232, and the outlet and the inlet are arranged opposite to each other.

[0055] Further, if Figure 1 , Figure 2 , Figure 4 As shown, the inflow end plate 232 and the outflow end plate 242 protrude from both sides of the bottom of the energy storage battery module 1.

[0056] The flow distribution of the coolant will affect the overall heat exchange effect. For channel heat exchangers, the inlet diversion design of the coolant needs to be considered. The use of horizontal inlet and outlet will result in obvious directionality of the coolant inflow and uneven flow distribution. When the coolant flows vertically into the heat exchanger, its flow is evenly distributed in all directions, which can improve the flow uniformity of the coolant.

[0057] The inflow end structure is consistent with the outflow end structure, protruding from both ends of the energy storage battery module 1, so that the inflow and outflow are connected to the vertical inlet pipeline 231 and the vertical outlet pipeline 241. The coolant flows in and out vertically from the inlet and outlet, and there is no initial velocity in the flow direction in the channel, which improves the uniformity of the coolant flow distribution and further improves the temperature uniformity. There is no side panel on the surface of the inflow and outflow end close to the channel, and this side is open and connected to the heat exchanger channel part.

[0058] Furthermore, the cross section of the heat exchange channel 21 is arranged in a micro-triangle shape, and the channel size is small, and the heat exchange area per unit volume is increased. The widest part of the micro-triangle is 21 mm and the height is 15 mm. The triangular channel size is small, and the channel fins of the triangular channel are inclined compared to the conventional rectangular channel, which can increase the heat dissipation area and improve the heat exchange performance.

[0059] The working process of the energy storage battery module thermal management structure of the present invention is as follows:

[0060] The coolant flows in from the vertical inlet pipe 231, flows into the heat exchange channel 21 evenly through the inlet and the transition space 233, and the coolant flowing through the heat exchange channel 21 directly contacts the bottom plate of the battery module for convection heat exchange. After heat exchange, the coolant takes away the heat, thereby achieving efficient cooling of the battery module.

[0061] like Figure 5 , Figure 6 As shown, the present invention also provides an energy storage battery module structure, including a battery cell 12 and a battery shell, the battery cell is arranged in the battery shell, the bottom of the battery shell is sealed and fastened to the aforementioned energy storage battery module thermal management structure, and the top of the heat exchange channel 21 of the energy storage battery module thermal management structure is in direct contact with the bottom of the battery shell.

[0062] Further, if Figure 6 As shown, the battery housing includes a battery bottom plate 14 , on which a battery side plate 13 is extended upward to seal and enclose the battery cell 12 , and a battery top plate 11 is sealed at the top of the battery side plate 13 ; the top of the heat exchange channel 21 is abutted and connected to the bottom surface of the battery bottom plate 14 .

[0063] In a specific embodiment, the top of the heat exchange channel 21 is welded to the bottom surface of the battery base plate 14, and the side of the inlet end plate 232 close to the heat exchange channel, the side of the outlet end plate 242 close to the heat exchange channel and the two heat exchanger side plates 25 are seamlessly welded to the battery base plate 14.

[0064] As described above, the energy storage battery module thermal management structure and energy storage battery module structure of the present invention have the following characteristics:

[0065] Beneficial effects:

[0066] In the present invention, the integrated triangular channel heat exchanger structure is embedded in the bottom of the energy storage battery module, and the coolant flowing through the heat exchange channel can directly contact the bottom of the energy storage battery module for heat exchange, thereby realizing efficient heat dissipation of the battery module; the cross section of the heat exchange channel is triangular, and the triangular channel is small in size, so that the heat exchange area per unit volume of the heat exchanger is large, and the oblique ribs of the triangular channel have a larger heat dissipation area than conventional straight channels, further improving the heat exchange capacity; the coolant of the heat exchanger enters and exits through the vertically arranged inlet and outlet structures, respectively, which improves the coolant's fluidity and distribution uniformity, and improves the utilization rate of space resources. The present invention can strengthen the cooling of energy storage battery modules, improve cooling efficiency, reduce the weight and volume of the battery system, and reduce energy consumption.

[0067] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
