[0062] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present 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.

[0063] In one embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a temperature regulating 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 a first flow guide component 100; the first surface of the second plate 20 is provided with a second flow guide component 200, and the first surface of the second plate 20 and the first surface of the first plate 10 are enclosed to form a receiving cavity; the second surface of the first plate 10 and / or the second surface of the second plate surface are used to fit the battery; the first flow guide component 100 is connected to the second flow guide component 200 to divide the receiving cavity into a plurality of flow channels 30; the flow channels 30 are used to transmit fluid and perform heat exchange on the battery through the fluid.

[0064] Among them, the temperature regulating structure can be used in a battery system; illustratively, 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 or side 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 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 or side of the single cell, so that the temperature regulating structure can regulate the temperature of the corresponding surface of the single cell. In addition, the temperature regulating structure can also be arranged in contact between two adjacent single cells, so that the temperature regulating structure can regulate the temperature of two adjacent single cells.

[0065] 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 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 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.

[0066] The first plate 10 has a first surface and a second surface opposite to each other. The first surface of the first plate 10 is provided with a first flow guide component 100. For example, the first flow guide component 100 and the first plate 10 may be an integrally formed structure. In another example, the first flow guide component 100 may also be provided on the first surface of the first plate 10 by welding or gluing. The first flow guide component 100 may divide the first surface of the first plate 10 into a plurality of first flow guide grooves, and the second flow guide component 200 may divide the first surface of the second plate 20 into a plurality of second flow guide grooves. When the first plate 10 and the second plate 20 are combined together, each first flow guide groove and each second flow guide groove are overlapped and arranged one by one, so that the first flow guide groove and the corresponding second flow guide groove are enclosed to form a corresponding flow channel 30. The fluid is transmitted through the corresponding flow channel 30. 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 zone, thereby improving the heat exchange efficiency of the first plate 10 or the second plate 20 to the battery. For another example, each first guide groove and each second guide groove are arranged to intersect each other in a one-to-one manner, so that a corresponding cross flow channel 30 is formed between the first guide groove and the corresponding second guide groove. The fluid flows crosswise in each flow channel 30. Turbulence is generated when the fluid flows through the contact. The fluid forms a larger vortex at the tail of the contact, thereby increasing the turbulence of the fluid. The fluid mixes with each other in the corresponding flow channel 30, thereby enhancing the heat exchange efficiency of the first plate 10 or the second plate 20.

[0067] Similarly, the second plate 20 has a first surface and a second surface opposite to each other, and the first surface of the second plate 20 is provided with a second flow guide component 200, for example, the second flow guide component 200 and the second plate 20 can be an integrally formed structure. In another example, the second flow guide component 200 can also be provided on the first surface of the second plate 20 by welding or gluing.

[0068] 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 closely 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 to 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 closely 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 to affect the heat exchange efficiency. It should be noted that the battery can be a lithium-ion battery, and the battery can be in a square shape. 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 surface, the right side surface, the front side surface or the rear side surface.

[0069] The first surface of the first plate 10 and the second surface of the second plate 20 can be tightly arranged by welding, screwing or bonding, so that a accommodating cavity is formed between the first plate 10 and the second plate 20, and the first guide component 100 and the second guide component 200 are abutted, so that a contact 50 can be formed at the connection between the first guide component 100 and the second guide component 200 to divide the accommodating cavity into a plurality of flow channels 30, and then 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 enters the accommodating cavity and is transmitted through each flow channel 30, so that the fluid performs heat exchange with the battery, thereby realizing rapid and accurate temperature regulation of the battery.

[0070] Exemplarily, an input interface is provided on the first plate 10 and / or the second plate 20, and an output interface is provided on the first plate 10 and / or the second plate 20, and the input interface and the output interface are respectively connected to each flow channel 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, the fluid can be pure water or a water mixture with additives.

[0071] In the above-mentioned embodiment, the first surface of the first plate 10 is provided with a first flow guide component 100; the first surface of the second plate 20 is provided with a second flow guide component 200, and the second plate 20 and the first plate 10 are enclosed to form a accommodating cavity; the second surface of the first plate 10 and / or the second surface of the second plate surface is used to fit the battery; the first flow guide component 100 is connected to the second flow guide component 200 to divide the accommodating cavity into a plurality of flow channels 30; the flow channels 30 are used to transmit fluid, and heat exchange is performed on the battery through the fluid to achieve temperature regulation of the corresponding sides of the battery. The present application arranges a first flow guide component 100 on the first surface of the first plate 10, arranges a second flow guide component 200 on the first surface of the second plate 20, and arranges the second surface of the first plate 10 or the second surface of the second plate 20 to be in contact with one side surface of the battery. The first flow guide component 100 is connected with the second flow guide component 200, and the accommodating cavity is divided into a plurality of flow channels 30, so that a plurality of contacts 50 are formed at the first flow guide component 100, the second flow guide component 200, and at the connection between the first flow guide component 100 and the second flow guide component 200. When the fluid enters the accommodating cavity, it can be transmitted through each flow channel 30. At the same time, when the fluid flows through the contacts, turbulence is generated, which increases the turbulence of the fluid. The fluids transmitted by the corresponding flow channels 30 mix with each other after flowing through the contacts, 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.

[0072] In one embodiment, Figures 1 to 4As shown, the first guide component 100 includes a plurality of first guide bars 112 and a plurality of second guide bars 114; the second guide component 200 includes a plurality of third guide bars 212 and a plurality of fourth guide bars 214; each first guide bar 112 is arranged in one-to-one correspondence with each second guide bar 114, and the first guide bar 112 and the corresponding second guide bar 114 are arranged at a first preset angle; each third guide bar 212 and each fourth guide bar 214 are arranged in one-to-one correspondence, and the third guide bar 212 and the corresponding fourth guide bar 214 are arranged at a second preset angle; the first guide bar 112 is connected to at least one third guide bar 212, and the second guide bar 114 is connected to at least one fourth guide bar 214.

[0073] Among them, the first guide bar 112 and the second guide bar 114 can be linear convex ribs.

There is a first preset angle between the first guide bar 112 and the second guide bar 114, and the first preset angle can be an obtuse angle or an acute angle. Exemplarily, at least a portion of the first guide bars 112 of each first guide bar 112 are arranged at intervals and have different lengths. At least a portion of the second guide bars 114 of each second guide bar 114 are arranged at intervals and have different lengths.

At least a portion of the fourth guide bars 214 of each fourth guide bar 214 are arranged at intervals and have different lengths.

[0076] The distance between two adjacent first guide bars 112 ranges from 8 to 16 mm, and the distance between two adjacent second guide bars 114 ranges from 6 to 14 mm, thereby forming a first gap of a certain distance between two adjacent first guide bars 112 so that the fluid can flow smoothly through the first gap; forming a second gap of a certain distance between two adjacent second guide bars 114 so that the fluid can flow smoothly through the second gap. Similarly, the distance between two adjacent third guide bars 212 ranges from 8 to 16 mm, and the distance between two adjacent fourth guide bars 214 ranges from 6 to 14 mm, thereby forming a third gap of a certain distance between two adjacent third guide bars 212 so that the fluid can flow smoothly through the third gap; forming a fourth gap of a certain distance between two adjacent fourth guide bars 214 so that the fluid can flow smoothly through the second gap.

[0078] In one example, the top surface of the first guide bar 112 can also be rounded, and the diameter of the rounded corners ranges from 0.2 to 0.8 mm; the top surface of the second guide bar 114 can also be rounded, and the diameter of the rounded corners ranges from 0.2 to 0.8 mm; the top surface of the third guide bar 212 can also be rounded, and the diameter of the rounded corners ranges from 0.2 to 0.8 mm; the top surface of the fourth guide bar 214 can also be rounded, and the diameter of the rounded corners ranges from 0.2 to 0.8 mm; so that the first guide bar 112 is connected to the corresponding third guide bar 212 to form a contact 50, and the second guide bar 114 is connected to the corresponding fourth guide bar 214 to form a contact 50. It should be noted that the heights of the first guide bar 112, the second guide bar 114, the third guide bar 212 and the fourth guide bar 214 are equal.

[0079] By arranging each first guide bar 112 and each second guide bar 114 on the first surface of the first plate 10, a contact 50 is formed between the first guide bar 112 and the corresponding second guide bar 114; arranging each third guide bar 212 and each fourth guide bar 214 on the first surface of the second plate 20, a contact 50 is formed between the third guide bar 212 and the corresponding fourth guide bar 214; based on the connection between the first guide bar 112 and the corresponding third guide bar 212, a contact 50 is formed between the first guide bar 112 and the corresponding third guide bar 212; based on The second guide bar 114 is connected to the corresponding fourth guide bar 214, and then a contact 50 is formed between the second guide bar 114 and the corresponding fourth guide bar 214, dividing the accommodating cavity formed by the first plate 10 and the second plate 20 into a plurality of flow channels 30, and then the fluid is transmitted in each flow channel 30. Turbulence will be generated when the fluid flows through the contact 50. The wider the flow channel 30 between adjacent contacts 50, the larger the vortex formed by the fluid at the tail of the contact 50, thereby increasing the turbulence of the fluid, and the fluid mixes with each other between the corresponding flow channels 30, thereby enhancing the heat exchange performance.

[0080] It should be noted that the higher the height of the guide bar (the first guide bar 112, the second guide bar 114, the third guide bar 212 or the fourth guide bar 214), the larger the recessed space between two adjacent guide bars (the first guide bar 112, the second guide bar 114, the third guide bar 212 or the fourth guide bar 214), which increases the turbulence of the fluid and can also enhance the heat exchange efficiency between the fluid and the plate (the first plate 10 and the second plate 20). The smaller the distance between two adjacent guide strips (the first guide strip 112, the second guide strip 114, the third guide strip 212 or the fourth guide strip 214), the better the heat exchange performance between the fluid and the plate (the first plate 10 and the second plate 20), mainly because the increase in the distance between the two adjacent guide strips will reduce the number of contacts, and the contacts between the plates (the first plate 10 and the second plate 20) can increase the disturbance of the fluid and enhance the heat exchange between the fluid and the plate wall. Therefore, the reduction of contacts will lead to a decrease in heat exchange capacity. When the distance between two adjacent guide strips (the first guide strip 112, the second guide strip 114, the third guide strip 212 or the fourth guide strip 214) is constant, the flow channel 30 formed when the first preset angle or the second preset angle is larger is wider, resulting in greater turbulence and stronger heat exchange performance.

[0081] In one embodiment, Figure 3 , Figure 7 and Fig.10 As shown, the first guide bar 112 is intersected with the corresponding third guide bar 212 , and the second guide bar 114 is intersected with the corresponding fourth guide bar 214 .

[0082] When the first plate 10 and the second plate 20 are combined together, the first guide bar 112 and the corresponding third guide bar 212 abut against each other, and the first guide bar 112 and the corresponding third guide bar 212 intersect each other, so that a contact point is formed between the first guide bar 112 and the corresponding third guide bar 212; the second guide bar 114 and the corresponding fourth guide bar 214 abut against each other, and the second guide bar 114 and the corresponding fourth guide bar 214 intersect each other, so that the second guide bar 114 and the corresponding fourth guide bar 214 are connected. A contact is formed between 14, so that each flow channel 30 in the accommodating cavity forms a cross flow channel 30, and then after the fluid enters the accommodating cavity, the fluid can cross-flow in each flow channel 30, and turbulence is generated when the fluid flows through the contact. The fluid forms a vortex at the contact, thereby increasing the turbulence of the fluid. The fluid mixes with each other in the cross flow channel 30, thereby enhancing the heat exchange efficiency of the first plate 10 or the second plate 20. The fluid exchanges heat with the battery, realizes rapid and accurate temperature regulation of the battery, and extends the service life of the battery.

[0083] In one embodiment, Figure 1 , Figure 2 and Figure 6 As shown, the first guide component 100 also includes a first guide trunk 116; the second guide component 200 also includes a second guide trunk 216; the first guide trunk 116 is provided with at least 2 first guide strips 112 and at least 2 second guide strips 114; the second guide trunk 216 is provided with at least 2 third guide strips 212 and at least 2 fourth guide strips 214.

[0084] The first flow guiding trunk 116 may be a linear convex rib. The first flow guiding trunk 116 and the first plate 10 may be an integrally formed structure; in another example, the first flow guiding trunk 116 may be disposed on the first surface of the first plate 10 by welding or gluing. The second flow guiding trunk 216 may be a linear convex rib. The second flow guiding trunk 216 and the second plate 20 may be an integrally formed structure; in another example, the second flow guiding trunk 216 may be disposed on the first surface of the second plate 20 by welding or gluing.

[0085] The first guide trunk 116 can be set on the first surface of the first plate 10 in an inclined manner, that is, the first guide trunk 116 and the side of the first plate 10 form a preset angle to divide the first surface of the first plate into a first area (such as the upper right area) and a second area (such as the lower left area). The first ends of at least two first guide bars 112 are connected and set on the first guide trunk 116, and each first guide bar 112 is located in the first area; the first ends of at least two second guide bars 114 are connected and set on the first guide trunk 116, and each second guide bar 114 is located in the second area. A contact is formed between the first guide bar 112 and the first guide trunk 116, and a contact is formed between the second guide bar 114 and the first guide trunk 116, thereby increasing the number of contacts. The contacts can increase the disturbance of the fluid and enhance the heat exchange between the fluid and the wall of the plate. Therefore, the increase in contacts improves the heat exchange capacity of the plate.

[0086] The second flow guiding trunk 216 can be set on the first surface of the second plate 20 in an inclined manner, that is, the second flow guiding trunk 216 and the side of the first plate 10 form a preset angle, so as to divide the first surface of the second plate into a third area (such as the upper right area) and a fourth area (such as the lower left area), and the first ends of at least two third flow guiding strips 212 are connected and set on the second flow guiding trunk 216, and each third flow guiding strip 212 is located in the third area; the first ends of at least two fourth flow guiding strips 214 are connected and set on the second flow guiding trunk 216, and each fourth flow guiding strip 214 is located in the second area, and a contact is formed between the third flow guiding strip 212 and the second flow guiding trunk 216, and a contact is formed between the fourth flow guiding strip 214 and the second flow guiding trunk 216, thereby further increasing the number of contacts, thereby increasing the disturbance of the fluid and enhancing the heat exchange between the fluid and the wall of the plate. Therefore, the increase in contacts improves the heat exchange capacity of the plate.

[0087] In one embodiment, Figure 1 , Figure 2 and Figure 6 As shown, the first flow guiding trunk 116 is arranged to intersect with the corresponding second flow guiding trunk 216 .

[0088] When the first plate 10 and the second plate 20 are combined together, the first flow guiding trunk 116 and the second flow guiding trunk 216 abut against each other, and the first flow guiding trunk 116 intersects with the corresponding second flow guiding trunk 216, thereby forming a contact point between the first flow guiding trunk 116 and the corresponding second flow guiding trunk 216, thereby increasing the number of contacts in the accommodating cavity, and then after the fluid enters the accommodating cavity, the fluid can cross-flow in each flow channel 30, and turbulence is generated when the fluid flows through the contact point. The fluid forms a vortex at the contact point, thereby increasing the turbulence of the fluid, and the fluid mixes with each other in the cross flow channel 30, thereby enhancing the heat exchange efficiency of the first plate 10 or the second plate 20, and 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, Figure 1 , Figure 2 and Figure 6 As shown, there is a third preset angle between the first guide trunk 116 and the corresponding first guide strip 112; there is a fourth preset angle between the first guide trunk 116 and the corresponding second guide strip 114; the third preset angle ranges from 30° to 150°, and the fourth preset angle ranges from 30° to 150°; there is a fifth preset angle between the second guide trunk 216 and the corresponding third guide strip 212; there is a sixth preset angle between the second guide trunk 216 and the corresponding fourth guide strip 214; the fifth preset angle ranges from 30° to 150°, and the sixth preset angle ranges from 30° to 150°.

[0090] By setting the corresponding first guide strips 112 and the first guide trunk 116 at a third preset angle, the first guide strips 112 are spaced apart, and when the interval between two adjacent first guide strips 112 is constant, a gap of a certain width is formed between the first guide strips 112 and the first guide trunk 116. When the third preset angle is larger, the corresponding flow channel 30 is wider, and when the fluid passes through the corresponding flow channel 30, the turbulence caused is greater, thereby improving the heat exchange efficiency of the corresponding position of the first plate 10.

[0091] Similarly, by setting the corresponding second guide strips 114 and the first guide trunk 116 at a fourth preset angle, each second guide strip 114 is arranged at intervals, and when the interval between two adjacent second guide strips 114 is constant, a gap of a certain width is formed between the second guide strip 114 and the first guide trunk 116. When the fourth preset angle is larger, the corresponding flow channel 30 formed is wider, and when the fluid passes through the corresponding flow channel 30, the turbulence caused is greater, thereby improving the heat exchange efficiency of the corresponding position of the first plate 10. By setting the fifth preset angle between the corresponding third guide strips 212 and the second guide trunk 216, the third guide strips 212 are arranged at intervals, and when the interval between two adjacent third guide strips 212 is constant, a gap of a certain width is formed between the third guide strips 212 and the second guide trunk 216. When the fifth preset angle is larger, the corresponding flow channel 30 is wider, and when the fluid passes through the corresponding flow channel 30, the turbulence caused is greater, thereby improving the heat exchange efficiency of the corresponding position of the second plate 20. By arranging the corresponding fourth guide strips 214 and the second guide trunk 216 at a sixth preset angle, the fourth guide strips 214 are arranged at intervals, and when the interval between two adjacent fourth guide strips 214 is constant, a gap of a certain width is formed between the fourth guide strips 214 and the second guide trunk 216. When the sixth preset angle is larger, the corresponding flow channel 30 is wider, and when the fluid passes through the corresponding flow channel 30, the turbulence caused is greater, thereby improving the heat exchange efficiency of the corresponding position of the second plate 20.

[0092] In one embodiment, Figure 6 , Figure 7 and Figure 8 As shown, the number of first guide trunks 116 is at least 2, and the number of second guide trunks 216 is at least 2; the first guide trunks 116, the first guide bars 112 connected to the corresponding first guide trunks 116, and the second guide bars 114 connected to the corresponding first guide trunks 116 constitute a first guide group 110; the two adjacent first guide groups 110 are symmetrically arranged based on the reference line 40; the second guide trunks 216, the third guide bars 212 connected to the corresponding second guide trunks 216, and the fourth guide bars 214 connected to the corresponding second guide trunks 216 constitute a second guide group 210; the two adjacent second guide groups 210 are symmetrically arranged based on the reference line 40.

[0093] The reference line 40 may be the middle dividing line of the first surface of the first plate 10 (or the second plate 20). For example, one first flow guide group 110 is disposed on the first side of the reference line 40 of the first plate 10, one first flow guide group 110 is disposed on the second side of the reference line 40 of the first plate 10, and two first flow guide groups 110 are symmetrically disposed based on the reference line 40. By disposing at least two groups of first flow guide groups 110 on the first surface of the first plate 10, the number of contact points can be increased, which is beneficial to improving the turbulence of the fluid, thereby improving the heat exchange efficiency of the first plate 10. At the same time, since at least two first flow guide trunks 116 are disposed on the first surface of the first plate 10, the strength of the first plate 10 is enhanced.

[0094] For another example, one second flow guide group 210 is disposed on the first side of the reference line 40 of the second plate 20, one second flow guide group 210 is disposed on the second side of the reference line 40 of the second plate 20, and two second flow guide groups 210 are symmetrically disposed based on the reference line 40. By disposing at least two groups of second flow guide groups 210 on the first surface of the second plate 20, the number of contact points can be increased, which is beneficial to improving the turbulence of the fluid, thereby improving the heat exchange efficiency of the second plate 20. At the same time, since at least two second flow guide trunks 216 are disposed on the first surface of the second plate 20, the strength of the second plate 20 is enhanced.

[0095] When the first plate 10 and the second plate 20 are combined together, each first guide group 110 and each second guide group 210 are in one-to-one correspondence with each other, and the first guide group 110 intersects with the corresponding second guide group 210, thereby forming a plurality of contacts between the first guide group 110 and the corresponding second guide group 210, so that each flow channel 30 in the accommodating cavity forms a cross flow channel 30, and then after the fluid enters the accommodating cavity, the fluid can flow crosswise in each flow channel 30, and turbulence is generated when the fluid flows through the contact point, and the fluid forms a vortex at the contact point, thereby increasing the turbulence of the fluid, further enhancing the heat exchange efficiency of the first plate 10 or the second plate 20, and the fluid performs heat exchange with the battery, thereby realizing rapid and accurate temperature regulation of the battery, and extending the service life of the battery.

[0096] In one embodiment, Fig. 9 , Fig.10 and Fig.11 As shown, two adjacent first flow guide groups 110 are arranged at intervals; and two adjacent second flow guide groups 210 are arranged at intervals.

[0097] For example, a first guide group 110 is provided on the first side of the reference line 40 of the first plate 10, a first guide group 110 is provided on the second side of the reference line 40 of the first plate 10, and two first guide groups 110 are arranged in parallel and spaced apart based on the reference line 40. By providing at least two groups of first guide groups 110 spaced apart and arranged in parallel on the first surface of the first plate 10, the width of the flow channel 30 and the number of contact points can be increased at the same time, and the turbulence of the fluid can be further increased, thereby improving the heat exchange efficiency of the first plate 10. For another example, a second guide group 210 is provided on the first side of the reference line 40 of the second plate 20, a second guide group 210 is provided on the second side of the reference line 40 of the second plate 20, and two second guide groups 210 are arranged in parallel and spaced apart based on the reference line 40. By arranging at least two sets of second flow guide groups 210 spaced apart and arranged in parallel on the first surface of the second plate 20, the width of the flow channel 30 and the number of contacts can be increased at the same time, further improving the turbulence of the fluid, thereby improving the heat exchange efficiency of the second plate 20.

[0098] In one embodiment, Fig.12 , Fig.13 and Fig.14 As shown, the first guide bars 112 connected to the corresponding first guide trunk 116 are arranged at intervals, and the distance between two adjacent first guide bars 112 is the first interval distance; the second guide bars 114 connected to the corresponding first guide trunk 116 are arranged at intervals, and the distance between two adjacent second guide bars 114 is the second interval distance; the first interval distance is greater than or less than the second interval distance; the third guide bars 212 connected to the corresponding second guide trunk 216 are arranged at intervals, and the distance between two adjacent third guide bars 212 is the third interval distance; the fourth guide bars 214 connected to the corresponding second guide trunk 216 are arranged at intervals, and the distance between two adjacent fourth guide bars 214 is the fourth interval distance; the third interval distance is greater than or less than the fourth interval distance.

[0099] For example, each first guide bar 112 connected to the corresponding first guide trunk 116 can be arranged at equal intervals, and each second guide bar 114 connected to the corresponding first guide trunk 116 can be arranged at equal intervals. By setting the first interval distance to be greater than or less than the second interval distance, the flow channel 30 on one side of the first guide trunk 116 is narrow, and the flow channel 30 on the other side of the first guide trunk 116 is wide. Each third guide bar 212 connected to the corresponding second guide trunk 216 can be arranged at equal intervals, and each fourth guide bar 214 connected to the corresponding second guide trunk 216 can be arranged at equal intervals. By setting the third interval distance to be greater than or less than the fourth interval distance, the flow channel 30 on one side of the second guide trunk 216 is narrow, and the flow channel 30 on the other side of the second guide trunk 216 is wide. When the first plate 10 and the second plate 20 are combined together, the width of the flow channel 30 can be increased at the same time, thereby improving the turbulence of the fluid and helping to enhance the heat exchange capacity of the plate. At the same time, the asymmetric structure can adjust the density of the flow channel 30 according to the actual heating conditions of the battery. For example, near the position where the battery heats up, the flow channel 30 is distributed more densely to enhance the heat exchange capacity of the flow channel 30. For example, at the position where the battery heats down, the flow channel 30 is distributed more sparsely to balance the pressure drop of the fluid flow.

[0100] In one embodiment, Fig.15 , Fig.16 and Fig.17 As shown, at least one first guide branch 118 is provided between two adjacent first guide bars 112 connected to the corresponding first guide trunk 116; at least one second guide branch 122 is provided between two adjacent second guide bars 114 connected to the corresponding first guide trunk 116; the adjacent first guide branches 118 form a seventh preset angle, and the adjacent second guide branches 122 form an eighth preset angle; the seventh preset angle ranges from 30° to 165°, and the eighth preset angle ranges from 30° to 165°. °; at least one third guide branch 218 is arranged between two adjacent third guide strips 212 connecting the corresponding second guide trunk 216; at least one fourth guide branch 222 is arranged between two adjacent fourth guide strips 214 connecting the corresponding second guide trunk 216; a ninth preset angle is formed between adjacent third guide branches 218, and a tenth preset angle is formed between adjacent fourth guide branches 222; the value range of the ninth preset angle is 30° to 165°, and the value range of the tenth preset angle is 30° to 165°.

[0101] Among them, the first guide branch 118, the second guide branch 122, the third guide branch 218 and the fourth guide branch 222 can be linear convex ribs. The first guide branch 118, the second guide branch 122, the third guide branch 218, the fourth guide branch 222 and the first plate 10 can be an integrally formed structure. The seventh preset angle can be an obtuse angle or an acute angle, for example, the seventh preset angle has a value range of 30° to 165°; the eighth preset angle can be an obtuse angle or an acute angle, for example, the eighth preset angle has a value range of 30° to 165°; the ninth preset angle can be an obtuse angle or an acute angle, for example, the ninth preset angle has a value range of 30° to 165°; the tenth preset angle can be an obtuse angle or an acute angle, for example, the tenth preset angle has a value range of 30° to 165°.

[0102] Exemplarily, the seventh preset angle, the eighth preset angle, the ninth preset angle and the tenth preset angle may be set to any one of the following combinations: the seventh preset angle is set to an acute angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an acute angle and the tenth preset angle is set to an acute angle; the seventh preset angle is set to an acute angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an acute angle and the tenth preset angle is set to an obtuse angle; the seventh preset angle is set to an acute angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an obtuse angle and the tenth preset angle is set to an acute angle; the seventh preset angle is set to an acute angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an obtuse angle and the tenth preset angle is set to an obtuse angle; the seventh preset angle is set to an acute angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an obtuse angle and the tenth preset angle is set to an obtuse angle; The ninth preset angle is set to an acute angle and the tenth preset angle is set to an obtuse angle; the seventh preset angle is set to an acute angle, the eighth preset angle is set to an obtuse angle, the ninth preset angle is set to an obtuse angle, and the tenth preset angle is set to an acute angle; the seventh preset angle is set to an acute angle, the eighth preset angle is set to an obtuse angle, the ninth preset angle is set to an obtuse angle, and the tenth preset angle is set to an obtuse angle; the seventh preset angle is set to an obtuse angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an obtuse angle, and the tenth preset angle is set to an acute angle; the seventh preset angle is set to an obtuse angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an obtuse angle, and the tenth preset angle is set to an obtuse angle; the seventh preset angle is set to an obtuse angle, the eighth preset angle is set to an acute angle, the ninth preset angle is set to an obtuse angle, and the tenth preset angle is set to an obtuse angle.

[0103] For example, the minimum distance between the first guide branch 118 and the first guide trunk 116 can be set to 2 mm, the minimum distance between the second guide branch 122 and the first guide trunk 116 can be set to 0.5 mm, the minimum distance between the third guide branch 218 and the second guide trunk 216 can be set to 2 mm, and the minimum distance between the fourth guide branch 222 and the second guide trunk 216 can be set to 0.5 mm. The spacing between two adjacent first guide branches 118 ranges from 4 to 16 mm; the spacing between two adjacent second guide branches 122 ranges from 4 to 16 mm; the spacing between two adjacent third guide branches 218 ranges from 4 to 16 mm; and the spacing between two adjacent fourth guide branches 222 ranges from 4 to 16 mm.

[0104] By setting the first guide branch 118 and the second guide branch 122 on the first surface of the first plate 10, and setting the third guide branch 218 and the fourth guide branch 222 on the first surface of the second plate 20, the number of contacts between the first plate 10 and the second plate is further increased, so that the fluid is transmitted in each flow channel 30, and the fluid can cross-flow in each flow channel 30. Turbulence will be generated when the fluid flows through the contacts, which increases the turbulence of the fluid. The fluid mixes with each other between the corresponding flow channels 30, further enhancing the heat exchange efficiency of the first plate 10 or the second plate 20. The fluid performs heat exchange on the battery, thereby realizing rapid and accurate temperature regulation of the battery and extending the service life of the battery.

[0105] In one embodiment, Fig.18 , Fig.19 and Fig. 20 As shown, the first guide bar 112 is overlapped with the corresponding third guide bar 212 , and the second guide bar 114 is overlapped with the corresponding fourth guide bar 214 .

[0106] For example, when the first plate 10 and the second plate 20 are combined together, the first guide bar 112 and the corresponding third guide bar 212 can be stacked in abutment with each other, and the second guide bar 114 and the corresponding fourth guide bar 214 can be stacked in abutment with each other, so that a flow channel 30 is enclosed between the corresponding first guide bar 112 and the third guide bar 212, and another flow channel 30 is enclosed between the corresponding second guide bar 114 and the fourth guide bar 214. After the fluid enters the accommodating cavity, the fluid can flow in each flow channel 30, thereby improving the flow smoothness of the fluid, allowing the fluid to flow evenly in each flow channel 30, and the fluid performs heat exchange with the battery, thereby achieving rapid and accurate temperature regulation of the battery, thereby extending the service life of the battery.

[0107] In one embodiment, Fig.18 , Fig.19 and Fig. 20As shown, the first guide bar 100 also includes at least one first diverter bar 124; the second guide bar 210 also includes at least one second diverter bar 224; a first opening 126 is provided between the first guide bar 112 and the corresponding second guide bar 114, and the first diverter bar 124 is spaced between two adjacent first openings 126; a second opening 226 is provided between the third guide bar 212 and the corresponding fourth guide bar 214, and the second diverter bar 224 is spaced between two adjacent second openings 226; the second diverter bar 224 is overlapped with the corresponding first diverter bar 124.

[0108] The first flow-dividing strip 124 and the second flow-dividing strip 224 can be long curved convex ribs. By setting the first flow-dividing strip 124 between two adjacent first openings 126, the fluid input to the first opening 126 can be diverted and transmitted; the first flow-dividing strip 124 can divide the flow channel 30 between two adjacent first flow-guiding strips 112 into two corresponding sub-flow channels, and divide the flow channel 30 between two adjacent second flow-guiding strips 114 into two corresponding sub-flow channels. By setting the second flow-dividing strip 224 between two adjacent second openings 226, the fluid input to the second opening 226 can be diverted and transmitted; the second flow-dividing strip 224 can divide the flow channel 30 between two adjacent third flow-guiding strips 212 into two corresponding sub-flow channels, and divide the flow channel 30 between two adjacent fourth flow-guiding strips 214 into two corresponding sub-flow channels.

[0109] When the first plate 10 and the second plate 20 are combined together, the first guide bar 112 and the corresponding third guide bar 212 can be stacked in abutment, the second guide bar 114 and the corresponding fourth guide bar 214 can be stacked in abutment, the first diverter bar 124 and the corresponding second diverter bar 224 are stacked in abutment, the first opening 126 and the corresponding second opening 226 are enclosed to form a through hole, and then the fluid enters through the corresponding through hole and is diverted and transmitted through the first diverter bar 124 and the corresponding second diverter bar 224, so that the fluid distribution is more uniform. For example, the fluid flows in through the first through hole, diverts along the corresponding sub-channel, and then merges into the second through hole from another sub-channel, and then continues to divert, and so on. The fluid will be strongly disturbed due to the periodic change of the flow direction, which enhances the heat exchange capacity between the fluid and the solid wall of the disturbance zone, and then the fluid performs efficient heat exchange with the battery, realizes rapid and accurate temperature regulation of the battery, and prolongs the service life of the battery.

[0110] It should be noted that the minimum diameter of the first opening 126 and the second opening 226 can be set to 2 mm. The minimum distance from the end of the first diverter strip 124 to the corresponding side of the first plate 10 can be set to 0.5 mm; the minimum distance from the end of the second diverter strip 224 to the corresponding side of the second plate 20 can be set to 0.5 mm.

[0114] 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.

[0115] For the specific description of the battery and the temperature adjustment structure, reference may be made to the specific description of the battery and the temperature adjustment structure in the above embodiments, which will not be repeated here.

[0116] A side surface of the battery is bonded to the second surface of the first plate or the second surface of the first plate, and a first flow guide component is provided on the first surface of the first plate; the second plate and the first plate are enclosed to form a receiving cavity, and a second flow guide component is provided on the first surface of the second plate; the first flow guide component is connected to the second flow guide component to divide the receiving cavity into a plurality of flow channels; the flow channels are used to transmit fluid, and heat exchange is performed on the battery through the fluid to achieve temperature regulation of the corresponding side surfaces of the battery.

[0117] In the above embodiment, a first flow guide component is arranged on the first surface of the first plate, a second flow guide component is arranged on the first surface of the second plate, the second surface of the first plate or the second surface of the second plate is arranged in contact with one side surface of the battery, and the first flow guide component is connected with the second flow guide component to divide the accommodating cavity into a plurality of flow channels, so that a plurality of contacts are formed at the first flow guide component, the second flow guide component and at the connection between the first flow guide component and the second flow guide component, and then when the fluid enters the accommodating cavity, it can be transmitted through each flow channel, and at the same time, when the fluid flows through the contacts, turbulence is generated, which increases the turbulence of the fluid. The fluids transmitted by the corresponding flow channels mix with each other after flowing through the contacts, thereby enhancing the heat exchange performance of the corresponding sides 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.
