[0059] Additionally, the term "plurality" shall mean two or more.

[0060] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0061] In one embodiment, Figure 1 、 Figure 4 and Figure 5 As shown, a temperature regulation structure is provided, including a first plate 10 and a second plate 20, wherein the first surface of the first plate 10 is provided with at least two groups of first guide groove groups 100; the first surface of the second plate 20 is arranged in contact with each first guide groove group 100, and the second surface of the first plate 10 and / or the second surface of the second plate surface is used to contact the battery; the first guide groove group 100 and the first surface of the second plate 20 are enclosed to form a guide channel group 30, and the guide channel group 30 is used to transmit fluid and perform heat exchange on the battery through the fluid.

[0062] Among them, the temperature regulating structure can be used in the battery system. For example, the battery system may include a battery case and a battery pack, the battery pack is arranged in the battery case, and the temperature regulating structure may be a panel of the battery case, for example, the temperature regulating structure may serve as the bottom surface or side surface of the battery case. For another example, the temperature regulating structure is separately arranged in the battery case, and the temperature regulating structure is arranged in contact with the corresponding side surface of the battery pack, so that the temperature regulating structure can regulate the temperature of the battery pack. In another example, the temperature regulating structure can also be arranged in contact with the bottom surface or side surface of the single battery, so that the temperature regulating structure can regulate the temperature of the corresponding surface of the single battery. In addition, the temperature regulating structure can also be arranged in contact between two adjacent single batteries, so that the temperature regulating structure can regulate the temperature of the two adjacent single batteries.

[0063] The first plate 10 can be a plate made of aluminum or copper, and the first plate 10 can be a plate made of a composite metal material with a high thermal conductivity. The first plate 10 can be a flat plate structure, and the shape of the first plate 10 can be, but not limited to, square, round, or oval. It should be noted that the shape and size of the first plate 10 can be determined according to the actual application scenario of the battery system. Similarly, the second plate 20 can be a plate made of aluminum or copper, and the second plate 20 can be a plate made of a composite metal material with a high thermal conductivity. The second plate 20 can be a flat plate structure, and the shape of the second plate 20 can be, but not limited to, square, round, or oval. It should be noted that the shape and size of the second plate 20 are the same as those of the first plate 10.

[0064] The first plate 10 has a first surface and a second surface facing each other. The first surface of the first plate 10 is provided with at least two first guide groove groups 100. For example, the first guide groove groups 100 and the first plate 10 may be integrally formed. In another example, the first guide groove groups 100 may be provided on the first surface of the first plate 10 by welding or gluing. The first guide groove group 100 may include a plurality of first guide grooves 110, each of which is distributed on the first surface of the first plate 10. When the first plate 10 and the second plate 20 are combined together, the first guide groove group 100 is fitted on the first surface of the second plate 20. For example, the first guide groove group 100 abuts the first surface of the second plate 20 to achieve a tight connection between the first guide groove group 100 and the first surface of the second plate 20, so that the first guide groove group 100 and the second plate 20 are enclosed to form a guide channel group 30. The fluid is transmitted through the guide channel group 30, and the fluid will be strongly disturbed due to the change in flow direction, thereby enhancing the heat exchange capacity between the fluid and the solid wall of the disturbance area, thereby improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery.

[0065] The second surface of the first plate 10 or the second surface of the second plate 20 can be used to fit the first surface of the battery. For example, the second surface of the first plate 10 and the first surface of the battery can be provided with thermally conductive adhesive to tightly fit the first surface of the battery to the second surface of the first plate 10, avoiding the presence of a gap between the second surface of the first plate 10 and the first surface of the battery, which would affect the heat exchange efficiency. For another example, the second surface of the second plate 20 and the first surface of the battery can be provided with thermally conductive adhesive to tightly fit the first surface of the battery to the second surface of the second plate 20, avoiding the presence of a gap between the second surface of the second plate 20 and the first surface of the battery, which would affect the heat exchange efficiency. It should be noted that the battery can be a lithium-ion battery, and the battery can have a square structure. The first surface of the battery can be the bottom surface or the side surface of the battery, and the side surface of the battery can be the left side, the right side, the front side, or the back side.

[0066] Each first guide groove group 100 can be tightly connected to the second surface of the second plate 20 by welding, screwing, or bonding. The first guide groove group 100 and the second plate 20 enclose a guide channel group 30. For example, the guide channel group 30 may include a plurality of guide channels 310. When the first surface of the battery is attached to the second surface of the first plate 10 and / or the second surface of the second plate 20, the fluid is transferred through each guide channel 310, thereby performing heat exchange with the battery, thereby achieving rapid and accurate temperature regulation of the battery.

[0067] Exemplarily, the first plate 10 and / or the second plate 20 are provided with an input interface, and the first plate 10 and / or the second plate 20 are provided with an output interface, and the input interface and the output interface are respectively connected to the guide channel group 30. The input interface is used to input fluid, and the output interface is used to output fluid. It should be noted that the fluid can be a coolant, for example, pure water or a water mixture with additives.

[0068] In the above embodiment, the first surface of the first plate 10 is provided with at least two groups of first guide groove groups 100; the first surface of the second plate 20 is arranged in contact with each first guide groove group 100, and the second surface of the first plate 10 and / or the second surface of the second plate surface is used to contact the first surface of the battery; the first guide groove group 100 and the first surface of the second plate 20 are enclosed to form a guide channel group 30, and the guide channel group 30 is used to transmit fluid, perform heat exchange on the battery through the fluid, and realize temperature regulation of the corresponding side of the battery. The present application arranges at least two first guide groove groups 100 on the first surface of the first plate 10, and the second surface of the first plate 10 or the second surface of the second plate 20 is arranged to be in contact with one side surface of the battery. The first guide groove group 100 and the first surface of the second plate 20 are enclosed to form a guide channel group 30. When the fluid enters the guide channel group 30 for transmission, turbulence will be generated when the fluid flows through the guide channel group 30, which increases the turbulence of the fluid and enhances the heat exchange performance of the corresponding side of the battery, thereby improving the heat exchange efficiency between the first plate 10 and the second plate 20 and extending the service life of the battery.

[0069] In one embodiment, Figure 2 and Figure 4 As shown, at least two groups of second guide groove groups 200 are provided on the first surface of the second plate 20; each first guide groove group 100 is provided in one-to-one correspondence with each second guide groove group 200, and the first guide groove group 100 and the corresponding second guide groove group 200 are enclosed to form a guide channel group 30.

[0070] The second plate 20 has a first surface and a second surface facing each other. The first surface of the second plate 20 is provided with at least two second guide groove groups 200. For example, the second guide groove groups 200 and the second plate 20 may be integrally formed. In another example, the second guide groove groups 200 may be provided on the first surface of the second plate 20 by welding or gluing. The second guide groove group 200 may include a plurality of second guide grooves 210, each of which is distributed on the first surface of the second plate 20. When the first plate 10 and the second plate 20 are combined together, each first guide groove group 100 and each second guide groove group 200 are arranged in a one-to-one correspondence. For example, the first guide groove group 100 is stacked and abutted against the corresponding second guide groove group 200 to achieve a close connection between the first guide groove group 100 and the corresponding second guide groove group 200, so that the first guide groove group 100 and the corresponding second guide groove group 200 are enclosed to form a guide channel group 30, thereby increasing the space of the guide channel group 30. The fluid is transmitted through the guide channel group 30, and the fluid will be strongly disturbed due to the change in flow direction, thereby enhancing the heat exchange capacity between the fluid and the solid wall of the disturbance area, thereby further improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery.

[0071] In one embodiment, Figure 1 、 Figure 2 and Figure 5 As shown, the first guide groove group 100 includes several first guide grooves 110; the second guide groove group 200 includes several second guide grooves 210; the guide channel group 30 includes several guide channels 310; the first surface of the first plate 10 is provided with several first guide strips 120 at intervals, and two adjacent first guide strips 120 are enclosed to form the first guide groove 110; the first surface of the second plate 20 is provided with several second guide strips 220 at intervals, and two adjacent second guide strips 220 are enclosed to form the second guide groove 210; the second guide groove 210 and the corresponding first guide groove 110 are enclosed to form the guide channel 310.

[0072] The first guide bars 120 and the second guide bars 220 can be zigzag ribs. For example, the first guide bars 120 are arranged at intervals on the first surface of the first plate 10, so that two adjacent first guide bars 120 enclose a first guide groove 110; and the second guide bars 220 are arranged at intervals on the first surface of the second plate 20, so that two adjacent second guide bars 220 enclose a second guide groove 210. When the first plate 10 and the second plate 20 are combined, the first guide grooves 110 and the corresponding second guide grooves 210 enclose a guide channel 310.

[0073] By arranging each first guide bar 120 on the first surface of the first plate 10 and each second guide bar 220 on the first surface of the second plate 20, based on the fitting arrangement of the first guide bar 120 and the corresponding second guide bar 220, a plurality of guide channels 310 are formed between the first plate 10 and the second plate 20, and the fluid is transmitted in each guide channel 310. When the fluid flows through each guide channel 310, turbulence will be generated, which increases the turbulence of the fluid and enhances the heat exchange performance of the corresponding side of the battery, thereby improving the heat exchange efficiency between the first plate 10 and the second plate 20 and extending the service life of the battery.

[0074] The distance between two adjacent first guide bars 120 ranges from 3 to 16 mm, and the distance between two adjacent second guide bars 220 ranges from 3 to 16 mm, thereby forming a first gap of a certain distance between the two adjacent first guide bars 120 so that the fluid can flow smoothly through the first gap; and forming a second gap of a certain distance between two adjacent second guide bars 220 so that the fluid can flow smoothly through the second gap.

[0075] In one embodiment, the height of the first guide bar 120 ranges from 2 to 4 mm, and the height of the second guide bar 220 ranges from 2 to 4 mm. This creates a certain distance between the first surface of the first plate 10 and the second surface of the second plate 20, allowing the fluid to fill each flow channel within the accommodating cavity and fully contact the inner walls of each flow channel, thereby improving heat exchange efficiency. It should be noted that the first guide bar 120 and the second guide bar 220 are equal in height.

[0076] It should be noted that the higher the height of the guide bar (the first guide bar 120 or the second guide bar 220), the larger the recessed space between two adjacent guide bars (the first guide bar 120 or the second guide bar 220), which increases the fluid turbulence and enhances the heat exchange efficiency between the fluid and the plates (the first plate 10 and the second plate 20). The smaller the spacing between two adjacent guide bars (the first guide bar 120 or the second guide bar 220), the better the heat exchange performance between the fluid and the plates (the first plate 10 and the second plate 20). This is mainly because increasing the spacing between two adjacent guide bars reduces the number of contact points. Contact points between the plates (the first plate 10 and the second plate 20) can increase fluid turbulence and enhance heat exchange between the fluid and the plate walls. Therefore, reducing the number of contact points will lead to a decrease in heat exchange capacity. When the distance between two adjacent guide bars (the first guide bar 120 or the second guide bar 220 ) is constant, a larger bending angle of the guide bars results in a wider flow channel, greater turbulence, and better heat exchange performance.

[0077] In one embodiment, Figure 3 and Figure 6 As shown, the first guide bar 120 includes a plurality of first bending segments 122 , and the first bending segments 122 are connected in series; the second guide bar 220 includes a plurality of second bending segments 222 , and the second bending segments 222 are connected in series.

[0078] The first bending section 122 may have a sawtooth structure. In another example, the first bending section 122 may also have an arc-shaped structure. The second bending section 222 may have a sawtooth structure. In another example, the second bending section 222 may also have an arc-shaped structure.

[0079] Based on the fact that the first guide bar 120 is composed of several first bending sections 122 and the second guide bar 220 is composed of several second bending sections 222, when the first plate 10 and the second plate 20 are combined together, the first guide bar 120 is fitted on the corresponding second guide bar 220, so that several guide channels 310 are formed between the first plate 10 and the second plate 20, and corresponding contacts 50 are formed at the bends of the guide channels 310. The fluid is transmitted through each guide channel 310, and the flow direction of the fluid changes when passing through the contacts 50. The fluid is then strongly disturbed due to the change in flow direction, which increases the turbulence of the fluid and enhances the heat exchange capacity between the fluid and the solid wall of the disturbance zone, thereby improving the heat exchange efficiency of the first plate 10 or the second plate 20 for the battery, realizing rapid and accurate temperature regulation of the battery, and extending the service life of the battery.

[0080] In one embodiment, Figure 3 and Figure 6 As shown, the first guide bar 120 includes at least one first bending sub-segment 124 and at least one second bending sub-segment 126; each first bending sub-segment 124 is connected in series with each second bending sub-segment 126; the bending direction of the first bending sub-segment 124 is opposite to the bending direction of the second bending sub-segment 126; the second guide bar 220 includes at least one third bending sub-segment 224 and at least one fourth bending sub-segment 226; each third bending sub-segment 224 is connected in series with each fourth bending sub-segment 226; the bending direction of the third bending sub-segment 224 is opposite to the bending direction of the fourth bending sub-segment 226.

[0081] The first bending sub-segment 124 and the second bending sub-segment 126 may have a sawtooth structure; in another example, the first bending sub-segment 124 and the second bending sub-segment 126 may also have an arc-shaped structure. The third bending sub-segment 224 and the fourth bending sub-segment 226 may have a sawtooth structure; in another example, the third bending sub-segment 224 and the fourth bending sub-segment 226 may also have an arc-shaped structure.

[0082] For example, each first bending sub-segment 124 and each second bending sub-segment 126 may be alternately connected, that is, one second bending sub-segment 126 is provided between two adjacent first bending sub-segments 124, the first bending sub-segment 124 bends vertically upward, and the second bending sub-segment 126 bends vertically downward, and each first bending sub-segment 124 and each second bending sub-segment 126 are connected to form a triangular wave-shaped or wavy first guide strip 120. Each third bending sub-segment 224 and each fourth bending sub-segment 226 may be alternately connected, that is, one fourth bending sub-segment 226 is provided between two adjacent third bending sub-segments 224, the third bending sub-segment 224 bends vertically upward, and the fourth bending sub-segment 226 bends vertically downward, and each third bending sub-segment 224 and each fourth bending sub-segment 226 are connected to form a triangular wave-shaped or wavy second guide strip 220.

[0083] When the first plate 10 and the second plate 20 are combined together, the first guide bar 120 is fitted on the corresponding second guide bar 220, so that a number of guide channels 310 are formed between the first plate 10 and the second plate 20, and then corresponding contacts 50 are formed at the bends of the first bending sub-segment 124, the second bending sub-segment 126, the third bending sub-segment 224 and the fourth bending sub-segment 226. The fluid is transmitted through each guide channel 310, thereby increasing the number of contacts 50. When the fluid passes through the contacts 50, the flow direction will change, and then it will be strongly disturbed due to the change in flow direction, further increasing the turbulence of the fluid, enhancing the heat exchange capacity between the fluid and the solid wall of the disturbance zone, thereby improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery, realizing rapid and accurate temperature regulation of the battery, and extending the service life of the battery.

[0087] It should be noted that when the second guide groove group 200 is not set on the first surface of the second plate 20, the folding angle of the first bending sub-segment 124 and the folding angle of the second bending sub-segment 126 can be set to any one of the following combinations: the folding angle of the first bending sub-segment 124 is an acute angle, the folding angle of the second bending sub-segment 126 is an acute angle, and the first surface of the second plate 20 is not set with the second guide groove group 200; the folding angle of the first bending sub-segment 124 is an acute angle, the folding angle of the second bending sub-segment 126 is an obtuse angle, and the first surface of the second plate 20 is not set with the second guide groove group 200; the folding angle of the first bending sub-segment 124 is an obtuse angle, the folding angle of the second bending sub-segment 126 is an acute angle, and the first surface of the second plate 20 is not set with the second guide groove group 200; the folding angle of the first bending sub-segment 124 is an obtuse angle, the folding angle of the second bending sub-segment 126 is an acute angle, and the first surface of the second plate 20 is not set with the second guide groove group 200.

[0088] By setting the angles of the first bending sub-segment 124 and the second bending sub-segment 126 on the first plate 10, as well as the angles of the third bending sub-segment 224 and the fourth bending sub-segment 226 on the second plate 20, when the fluid enters the corresponding guide channel 310, the fluid can flow crosswise or directly in each guide channel 310. When the fluid flows through the contact 50 at the corner, turbulence is generated, which increases the turbulence of the fluid and further enhances the heat exchange efficiency of the first plate 10 or the second plate 20. The fluid performs heat exchange on the battery, thereby achieving rapid and accurate temperature regulation of the battery and extending the service life of the battery.

[0089] In one embodiment, two adjacent first guide bars 120 are arranged in parallel and spaced apart, and two adjacent second guide bars 220 are arranged in parallel and spaced apart; or, two adjacent first guide bars 120 are arranged in symmetrical spaced apart, and two adjacent second guide bars 220 are arranged in symmetrical spaced apart.

[0090] For example, Figure 1 、 Figure 5 and Figure 7 As shown, two adjacent first guide bars 120 are arranged in parallel and spaced apart, thereby forming corresponding first guide grooves 110 with the same width from the input port to the output port; two adjacent second guide bars 220 are arranged in parallel and spaced apart, thereby forming corresponding second guide grooves 210 with the same width from the input port to the output port, that is, the width of the guide channels 310 formed thereby is the same. When the fluid enters the corresponding guide channel 310 for transmission, the transmission flow of the fluid into the guide channel 310 is increased, thereby enhancing the heat exchange performance of the corresponding side of the battery.

[0091] For example, Figure 9 and Figure 10 As shown, two adjacent first guide bars 120 are symmetrical and spaced apart, thereby forming a corresponding first guide groove 110 with a smaller width for the input port and a larger width for the output port; two adjacent second guide bars 220 are symmetrical and spaced apart, thereby forming a corresponding second guide groove 210 with a smaller width for the input port and a larger width for the output port, that is, the diameter of the input through-hole of the guide channel 310 formed thereby is smaller and the diameter of the output through-hole is larger. When the fluid enters the corresponding guide channel 310 through the input through-hole, the flow rate can be increased, the pressure can be reduced, the outlet cross-sectional area suddenly increases, the fluid will be ejected, and the fluid distribution can be made more even, thereby enhancing the heat exchange performance of the corresponding side of the battery, thereby improving the heat exchange efficiency of the first plate 10 and the second plate 20, and extending the service life of the battery.

[0092] In one embodiment, Figure 11 and Figure 12As shown, the first guide trough group 100 is provided with a plurality of first guide blocks 130 and a plurality of second guide blocks 140; the size of the first guide block 130 is larger than the size of the second guide block 140; each first guide block 130 is arranged at intervals, and a second guide block 140 is arranged between two adjacent first guide blocks 130; the second guide trough group 200 is provided with a plurality of third guide blocks 230 and a plurality of fourth guide blocks 240; the size of the third guide block 230 is larger than the size of the fourth guide block 240; each third guide block 230 is arranged at intervals, and a fourth guide block 240 is arranged between two adjacent third guide blocks 230; each first guide block 130 is arranged in one-to-one correspondence with each third guide block 230, and each second guide block 140 is arranged in one-to-one correspondence with each fourth guide block 240.

[0093] The first guide block 130, the second guide block 140, the third guide block 230, and the fourth guide block 240 may be square in shape. For example, the first guide block 130, the second guide block 140, the third guide block 230, and the fourth guide block 240 may be prismatic in shape. For example, the minimum diameter of the first guide block 130 ranges from 2 to 6 mm, the minimum diameter of the second guide block 140 ranges from 0.4 to 1.6 mm, the minimum diameter of the third guide block 230 ranges from 2 to 6 mm, and the minimum diameter of the fourth guide block 240 ranges from 0.4 to 1.6 mm.

[0094] For example, the size of the first guide block 130 can be set to be larger or smaller than the size of the second guide block 140. By arranging the first guide blocks 130 at intervals and arranging the second guide block 140 between two adjacent first guide blocks 130, the first guide blocks 130 and the second guide blocks 140 are alternately arranged, thereby forming two types of recesses between the first guide blocks 130 and the second guide blocks 140. The size of the third guide block 230 can be set to be larger or smaller than the size of the fourth guide block 240. By arranging the third guide blocks 230 at intervals and arranging the fourth guide block 240 between two adjacent third guide blocks 230, the third guide blocks 230 and the fourth guide blocks 240 are alternately arranged, thereby forming two types of recesses between the third guide blocks 230 and the fourth guide blocks 240.

[0095] When the first plate 10 and the second plate 20 are combined together, the first guide block 130 is fitted on the corresponding third guide block 230, and the second guide block 140 is fitted on the corresponding fourth guide block 240, so that a plurality of guide channels 310 are formed between the first plate 10 and the second plate 20, and then a plurality of recesses are formed on the guide channels 310. When the fluid enters the guide channels 310, when the fluid flows through the recesses, it disturbs the fluid near the wall, and generates a secondary flow at the recesses. When the input fluid flows to the first type of recess, it is divided into two fluid paths for transmission; when the fluid flows to the second type of recess, it is divided into two fluid paths for transmission; the hot fluid generated by the secondary flow at the recesses mixes with the mainstream fluid, continuously destroying the thermal boundary layer, thereby enhancing the heat transfer effect, thereby improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery, realizing rapid and accurate temperature regulation of the battery, and extending the service life of the battery.

[0096] In one embodiment, Figure 13 and Figure 14 As shown, the first guide groove group 100 includes several first guide grooves 110; the second guide groove group 200 includes several second guide grooves 210; the guide channel group 30 includes several guide channels 310; the first guide grooves 110 are arranged in an array, and the second guide grooves 210 are arranged in an array; the first guide grooves 110 and the second guide grooves 210 correspond one by one to form a guide channel 310; the first guide groove 110 includes several first guide sub-grooves 112 and several second guide sub-grooves 114; a second guide sub-groove 114 is arranged between two adjacent first guide sub-grooves 112; the second guide groove 210 includes several third guide sub-grooves 212 and several fourth guide sub-grooves 214; a fourth guide sub-groove 214 is arranged between two adjacent third guide sub-grooves 212.

[0097] The first flow guide groove 112, the second flow guide groove 114, the third flow guide groove 212 and the fourth flow guide groove 214 may be annular grooves. For example, the first flow guide groove 112, the second flow guide groove 114, the third flow guide groove 212 and the fourth flow guide groove 214 may be prismatic grooves.

[0098] For example, the size of the first guide groove 112 can be set to be larger than or smaller than the size of the second guide groove 114, by arranging each first guide groove 112 at intervals, and arranging the second guide groove 114 at intervals between two adjacent first guide grooves 112, thereby forming the first guide grooves 112 and the second guide grooves 114 alternately arranged, and each first guide groove 112 and each second guide groove 114 of the corresponding first guide groove 110 are connected in sequence, so that a cross contact is formed between the first guide groove 112 and the corresponding second guide groove 114. The size of the third guide sub-groove 212 can be set to be larger than or smaller than the size of the fourth guide sub-groove 214. By arranging the third guide sub-grooves 212 at intervals and arranging the fourth guide sub-grooves 214 at intervals between two adjacent third guide sub-grooves 212, the third guide sub-grooves 212 and the fourth guide sub-grooves 214 are alternately arranged, and the third guide sub-grooves 212 and the fourth guide sub-grooves 214 of the corresponding second guide groove 210 are connected in sequence, so that cross contacts are formed between the third guide sub-grooves 212 and the corresponding fourth guide sub-grooves 214.

[0099] When the first plate 10 and the second plate 20 are combined together, the first guide groove 110 and the corresponding second guide groove 210 enclose the corresponding guide channel 310, thereby forming multiple cross contacts on the guide channel 310. The fluid enters the guide channel 310, and turbulence is generated when the fluid flows through the cross contacts, which increases the turbulence of the fluid and enhances the heat exchange performance of the corresponding side of the battery, thereby improving the heat exchange efficiency between the first plate 10 and the second plate 20 and extending the service life of the battery.

[0100] In one embodiment, Figure 1 、 Figure 2 and Figure 5 As shown, the first surface of the first plate 10 is also provided with a first guide trunk groove 150; the first surface of the second plate 20 is also provided with a second guide trunk groove 250; the first guide trunk groove 150 and the second guide trunk groove 250 are enclosed to form a guide trunk channel 40; at least one first guide trunk group 100 is provided on the first side of the first guide trunk groove 150, and at least one first guide trunk group 100 is provided on the second side of the first guide trunk groove 150; at least one second guide trunk group 200 is provided on the first side of the second guide trunk groove 250, and at least one second guide trunk group 200 is provided on the second side of the second guide trunk groove 250.

[0101] For example, the first main flow guiding groove 150 and the first plate 10 can be integrally formed. In another example, the first main flow guiding groove 150 can be disposed on the first surface of the first plate 10 by welding or gluing. The second main flow guiding groove 250 and the second plate 20 can be integrally formed. In another example, the second main flow guiding groove 250 can be disposed on the first surface of the second plate 20 by welding or gluing.

[0102] When the first plate 10 and the second plate 20 are combined together, the first guide trunk groove 150 and the second guide trunk groove 250 are abutted and stacked to achieve a close connection between the first guide trunk groove 150 and the second guide trunk groove 250, and then the first guide trunk groove 150 and the second guide trunk groove 250 are enclosed to form a guide trunk channel 40, and the fluid is transmitted through the guide trunk channel 40. When the fluid flows through the guide trunk channel 40, the flow channel is wider, which increases the heat exchange area, and the fluid will be strongly disturbed due to the change in flow direction, thereby enhancing the heat exchange capacity between the fluid and the solid wall surface of the disturbance area, thereby improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery.

[0103] In one embodiment, Figure 1 、 Figure 5 and Figure 7 As shown, each first guide groove group 100 is symmetrically arranged based on the first guide groove 150; each second guide groove group 200 is symmetrically arranged based on the first guide groove 150.

[0104] For example, the first main flow guiding groove 150 may be disposed in the middle of the first surface of the first plate 10 ; and the second main flow guiding groove 250 may be disposed in the middle of the first surface of the second plate 20 .

[0105] One first guide channel group 100 is provided on the first side of the first guide channel main channel 150 , one first guide channel group 100 is provided on the second side of the first guide channel main channel 150 , and the two first guide channel groups 100 are symmetrically arranged based on the first guide channel main channel 150 . A second guide groove group 200 is provided on the first side of the second guide groove 250, and a second guide groove group 200 is provided on the second side of the second guide groove 250, and the two second guide groove groups 200 are symmetrically arranged based on the second guide groove 250. When the first plate 10 and the second plate 20 are combined together, and then when the fluid enters the guide channel group 30 for transmission, the fluid flowing through the guide channel group 30 will generate turbulence, and at the same time the fluid will enter the guide main channel 40 for transmission, which can make the flow distribution more uniform, increase the flow channels, increase the contact points of the flow channels, increase the disturbance of the fluid, enhance the heat exchange between the fluid and the wall, and thus enhance the heat exchange performance of the corresponding side of the battery, improve the heat exchange efficiency of the first plate 10 and the second plate 20, and extend the service life of the battery.

[0106] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, a plurality of fifth guide blocks 160 are provided in the first guide trunk groove 150; the fifth guide blocks 160 are arranged at intervals; a plurality of sixth guide blocks 260 are provided in the second guide trunk groove 250; the sixth guide blocks 260 are arranged at intervals.

[0107] The fifth guide block 160 may be square. For example, the fifth guide block 160 may be prismatic. By arranging the fifth guide blocks 160 at intervals, a recess is formed between two adjacent fifth guide blocks 160. By arranging the sixth guide blocks 260 at intervals, a recess is formed between two adjacent sixth guide blocks 260.

[0108] When the first plate 10 and the second plate 20 are combined together, the fifth guide block 160 is fitted on the corresponding sixth guide block 260, so that a guide trunk channel 40 is formed between the first plate 10 and the second plate 20, and then a plurality of recesses are formed on the guide trunk channel 40. When the fluid enters the guide trunk channel 40, it will disturb the fluid near the wall when flowing through the recesses, and generate secondary flow at the recesses. When the input fluid flows into the recesses, it is divided into two fluid paths for transmission, that is, the fluid crosses and diverts in the guide trunk channel 40, continuously destroying the thermal boundary layer, thereby enhancing the heat transfer effect and the turbulence intensity, further improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery, realizing rapid and accurate temperature regulation of the battery, and extending the service life of the battery.

[0109] In one embodiment, Figure 7 and Figure 8 As shown, a third guide bar group 170 is provided in the first guide trunk groove 150; a fourth guide bar group 270 is provided in the first guide trunk groove 150; the third guide bar group 170 includes two third guide bars 172; the two third guide bars 172 are intersectingly arranged; the fourth guide bar group 270 includes two fourth guide bars 272; the two fourth guide bars 272 are intersectingly arranged.

[0110] The third guide strip 172 and the fourth guide strip 272 may be zigzag ribs.

[0111] By intersecting the two third guide bars 172 and the two fourth guide bars 272, when the first plate 10 and the second plate 20 are combined, the third guide bar group 170 and the fourth guide bar group 270 are arranged in a close-fitting manner, thereby forming several intersecting contact points within the main guide channel 40. As the fluid is transmitted within the main guide channel 40, the fluid flowing through the intersecting contact points within the main guide channel 40 generates turbulence, increasing the fluid turbulence and enhancing the heat exchange performance on the corresponding sides of the battery. This improves the heat exchange efficiency between the first plate 10 and the second plate 20, thereby extending the battery life. At the same time, the third guide bar group 170 is provided on the first plate 10, and the fourth guide bar group 270 is provided on the second plate 20, thereby enhancing the strength of the first plate 10 and the second plate 20.

[0112] In one embodiment, the two third guide bars 172 enclose a plurality of first concave units or a plurality of first convex units; the two fourth guide bars 272 enclose a plurality of second concave units or a plurality of second convex units.

[0113] For example, two third guide bars 172 enclose a plurality of first concave units, i.e., the intersection of the two third guide bars 172 is a concave portion; two fourth guide bars 272 enclose a plurality of second concave units, i.e., the intersection of the two fourth guide bars 272 is a concave portion, thereby increasing the heat exchange area, and the fluid flowing through the first concave units forms a cross flow, increasing turbulence and enhancing heat exchange efficiency. For another example, two third guide bars 172 enclose a plurality of first convex units, i.e., the intersection of the two third guide bars 172 is a convex portion; two fourth guide bars 272 enclose a plurality of second convex units, i.e., the intersection of the two fourth guide bars 272 is a convex portion, thereby enhancing the strength of the middle portion of the plate and dividing the main guide channel 40 into two upper and lower sub-channels, thereby controlling the flow rate, enhancing the heat transfer coefficient, and balancing the pressure in the main guide channel 40.

[0114] In one embodiment, Figure 9 and Figure 10 As shown, two adjacent first guide groove groups 100 are symmetrically arranged based on a first reference line; and two adjacent second guide groove groups 200 are symmetrically arranged based on a second reference line.

[0115] Exemplarily, the first guide groove group 100 includes two first guide grooves 110, and the two first guide grooves 110 within the same first guide groove group 100 are symmetrically arranged; the second guide groove group 200 includes two second guide grooves 210, and the two second guide grooves 210 within the same second guide groove group 200 are symmetrically arranged. The first guide groove 110 can be triangular or wavy, and the second guide groove 210 can be triangular or wavy. For example, the fold angle of the first guide groove 110 can be an obtuse angle, and the fold angle of the first guide groove 110 can range from 95° to 165°; the fold angle of the second guide groove can be an obtuse angle, and the fold angle of the second guide groove 210 can range from 95° to 165°. The minimum spacing within the first guide groove 110 is in the range of 0.5 mm. The diameter of the input through-hole of the guide channel 310 formed by the first guide groove group 100 and the corresponding second guide groove group 200 is relatively small. When the fluid enters the corresponding guide channel 310 through the input through-hole, the flow rate can be increased, the pressure can be reduced, the outlet cross-sectional area suddenly increases, and the fluid will be ejected, which can make the fluid distribution more uniform, thereby enhancing the heat exchange performance of the corresponding side of the battery, thereby improving the heat exchange efficiency of the first plate 10 and the second plate 20, and extending the service life of the battery.

[0116] In one embodiment, a battery system is further provided, comprising a battery and a temperature regulating structure as described above; one side of the battery is fitted on the temperature regulating structure.

[0117] For the detailed description of the battery and the temperature regulating structure, please refer to the detailed description of the battery and the temperature regulating structure in the above embodiments, which will not be repeated here.

[0118] One side of the battery is bonded to the second side of the first plate or the second side of the first plate, and the first side of the first plate is provided with at least two groups of first guide groove groups; the first side of the second plate is bonded to each first guide groove group; the first guide groove group and the second plate are enclosed to form a guide channel group, which is used to transmit fluid, perform heat exchange on the battery through the fluid, and achieve temperature regulation of the corresponding side of the battery.

[0119] In the above-mentioned embodiment, at least two groups of first guide groove groups are arranged on the first surface of the first plate, and the second surface of the first plate or the second surface of the second plate is arranged to fit one side surface of the battery. The first guide groove group and the first surface of the second plate are enclosed to form a guide channel group. When the fluid enters the guide channel group for transmission, turbulence will be generated when the fluid flows through the guide channel group, which increases the turbulence of the fluid and enhances the heat exchange performance of the corresponding side of the battery, thereby improving the heat exchange efficiency of the first plate and the second plate and extending the service life of the battery system.

[0120] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
