[0059] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0060] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0061] Additionally, the term "plurality" shall mean two or more.

[0062] 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.

[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 are used to fit the battery; the first flow guide component 100 is connected to the second flow guide component 200 to separate 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] The temperature regulating structure can be used in a battery system. For example, the battery system may include a battery case and a battery pack, the battery pack being disposed 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 surface of the battery case. In another example, the temperature regulating structure may be disposed separately in the battery case, and the temperature regulating structure may be attached to the corresponding side surface of the battery pack, so that the temperature regulating structure may regulate the temperature of the battery pack. In another example, the temperature regulating structure may also be attached to the bottom or side surface of a single cell, so that the temperature regulating structure may regulate the temperature of the corresponding surface of the single cell. In addition, the temperature regulating structure may also be attached between two adjacent single cells, so that the temperature regulating structure may regulate the temperature of the 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 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.

[0066] The first plate 10 has a first surface and a second surface facing each other. A first flow guide assembly 100 is provided on the first surface of the first plate 10. For example, the first flow guide assembly 100 and the first plate 10 may be integrally formed. In another example, the first flow guide assembly 100 may be provided on the first surface of the first plate 10 by welding or gluing. The first flow guide assembly 100 may divide the first surface of the first plate 10 into a plurality of first flow guide grooves, and the second flow guide assembly 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, each first flow guide groove overlaps with each second flow guide groove, forming a corresponding flow channel 30 between the first flow guide groove and the corresponding second flow guide groove. When the fluid is transported through the corresponding flow channel 30, the fluid is 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 for the battery. For another example, each first guide groove and each second guide groove are arranged to intersect with each other in a one-to-one correspondence, so that the first guide groove and the corresponding second guide groove form a corresponding cross flow channel 30. The fluid flows crosswise in each flow channel 30, and 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 facing each other. The first surface of the second plate 20 is provided with a second flow guide assembly 200. For example, the second flow guide assembly 200 and the second plate 20 may be integrally formed. In another example, the second flow guide assembly 200 may 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 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.

[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 flow guide component 100 and the second flow guide component 200 are abutted, so that a contact 50 can be formed at the connection between the first flow guide component 100 and the second flow 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, and then the fluid performs heat exchange with the battery, thereby realizing rapid and accurate temperature regulation of the battery.

[0070] 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 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, pure water or a water mixture with additives.

[0071] In the above 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 are 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, and arranges a second flow guide component 200 on the first surface of the second plate 20. The second surface of the first plate 10 or the second surface of the second plate 20 is arranged in contact with one side surface of the battery. The first flow guide component 100 is connected to 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 the connection between the first flow guide component 100 and the second flow guide component 200. Then, 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 sides 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 assembly 100 includes a plurality of first guide bars 112 and a plurality of second guide bars 114; the second guide assembly 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] The first guide bar 112 and the second guide bar 114 can be linear ribs. For example, the first end of the first guide bar 112 is connected to the first end of the corresponding second guide bar 114, the second end of the first guide bar 112 can extend to the corresponding side of the first plate 10, and the second end of the second guide bar 114 can extend to the corresponding side of the first plate 10. 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.

[0074] The first end of the third guide bar 212 is connected to the first end of the corresponding fourth guide bar 214. The second end of the third guide bar 212 can extend to the corresponding side edge of the second plate 20, and the second end of the fourth guide bar 214 can extend to the corresponding side edge of the second plate 20. The third guide bar 212 and the fourth guide bar 214 form a second predetermined angle between them, which can be an obtuse angle or an acute angle. For example, at least a portion of the third guide bars 212 are arranged at intervals and have different lengths. At least a portion of the fourth guide bars 214 are arranged at intervals and have different lengths.

[0075] Exemplarily, the first preset angle and the second preset angle can be set to any one of the following combinations: the first preset angle is set to an acute angle and the second preset angle is set to an obtuse angle, the first preset angle is an acute angle and the second preset angle is set to an acute angle, the first preset angle is an obtuse angle and the second preset angle is set to an obtuse angle.

[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. This allows a first gap of a certain distance to be formed between the two adjacent first guide bars 112, allowing fluid to flow smoothly through the first gap; and a second gap of a certain distance to be formed between the two adjacent second guide bars 114, allowing fluid to 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. This allows a third gap of a certain distance to be formed between the two adjacent third guide bars 212, allowing fluid to flow smoothly through the third gap; and a fourth gap of a certain distance to be formed between the two adjacent fourth guide bars 214, allowing fluid to flow smoothly through the second gap.

[0077] In one embodiment, the height of the first guide bar 112 ranges from 2 to 4 mm, and the height of the second guide bar 114 ranges from 2 to 4 mm; the thickness of the first guide bar 112 ranges from 0.3 to 2 mm, and the thickness of the second guide bar 114 ranges from 0.3 to 2 mm. Similarly, the height of the third guide bar 212 ranges from 2 to 4 mm, and the height of the fourth guide bar 214 ranges from 2 to 4 mm; the thickness of the third guide bar 212 ranges from 0.3 to 2 mm, and the thickness of the fourth guide bar 214 ranges from 0.3 to 2 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 30 within the accommodating cavity, allowing the fluid to fully contact the inner wall of each flow channel 30, thereby improving heat exchange efficiency.

[0078] In one example, the top surface of the first guide bar 112 can be chamfered, with the diameter of the fillet ranging from 0.2 to 0.8 mm; the top surface of the second guide bar 114 can be chamfered, with the diameter of the fillet ranging from 0.2 to 0.8 mm; the top surface of the third guide bar 212 can be chamfered, with the diameter of the fillet ranging from 0.2 to 0.8 mm; the top surface of the fourth guide bar 214 can be chamfered, with the diameter of the fillet ranging 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 the contact 50, and the second guide bar 114 is connected to the corresponding fourth guide bar 214 to form the 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 point 50 is formed between the first guide bar 112 and the corresponding second guide bar 114; by arranging each third guide bar 212 and each fourth guide bar 214 on the first surface of the second plate 20, a contact point 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 point 50 is formed between the first guide bar 112 and the corresponding third guide bar 212; based on the connection between the first guide bar 112 and the corresponding third guide bar 212, a contact point 50 is formed between the first guide bar 112 and the corresponding third guide bar 212; The second guide bar 114 is connected to the corresponding fourth guide bar 214, and 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. When the fluid flows through the contact 50, turbulence will be generated. 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 the 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 spacing 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), the better the heat exchange performance between the fluid and the plates (the first plate 10 and the second plate 20). This is primarily 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, a reduction in contact points leads to a decrease in heat exchange capacity. When the spacing 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) is constant, a larger first or second preset angle results in a wider flow channel 30, resulting in greater turbulence and improved heat exchange performance.

[0081] In one embodiment, Figure 3 、 Figure 7 and Figure 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, thereby forming a contact point 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, thereby forming a contact point between the second guide bar 114 and the corresponding fourth guide bar 214. 14, so that the flow channels 30 in the accommodating cavity form a cross flow channel 30, and then after the fluid enters the accommodating cavity, the fluid can cross-flow in the flow channels 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. 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 performs heat exchange on 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 assembly 100 also includes a first guide trunk 116; the second guide assembly 200 also includes a second guide trunk 216; the first guide trunk 116 is provided with at least 2 first guide bars 112 and at least 2 second guide bars 114; the second guide trunk 216 is provided with at least 2 third guide bars 212 and at least 2 fourth guide bars 214.

[0084] The first flow guiding trunk 116 can be a linear rib. The first flow guiding trunk 116 and the first plate 10 can be integrally formed. In another example, the first flow guiding trunk 116 can be welded or glued to the first surface of the first plate 10. The second flow guiding trunk 216 can be a linear rib. The second flow guiding trunk 216 and the second plate 20 can be integrally formed. In another example, the second flow guiding trunk 216 can be welded or glued to the first surface of the second plate 20.

[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. Contacts are formed between the first guide bar 112 and the first guide trunk 116, and contacts are 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 forms a preset angle with the side of the first plate 10, 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). 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. Contact points are formed between the third flow guiding strip 212 and the second flow guiding trunk 216, and contact points are formed between the fourth flow guiding strip 214 and the second flow guiding trunk 216, thereby further increasing the number of contact points, thereby increasing the disturbance of the fluid and enhancing the heat exchange between the fluid and the plate wall. Therefore, the increase in contact points 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 intersected 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. 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 vortices at the contact point, 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 performs heat exchange on the battery, realizes rapid and accurate temperature regulation of the battery, and extends 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 bar 112; there is a fourth preset angle between the first guide trunk 116 and the corresponding second guide bar 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 bar 212; there is a sixth preset angle between the second guide trunk 216 and the corresponding fourth guide bar 214; the fifth preset angle ranges from 30° to 150°, and the sixth preset angle ranges from 30° to 150°.

[0090] By arranging the corresponding first guide strips 112 and the first guide trunk 116 at a third preset angle, the first guide strips 112 are arranged at intervals. When the spacing 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 spacing 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 arranging the corresponding third guide strips 212 and the second guide trunk 216 at a fifth preset angle, the third guide strips 212 are spaced apart, and when the spacing 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 spaced apart, and when the spacing 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 connecting the corresponding first guide trunks 116, and the second guide bars 114 connecting 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 connecting the corresponding second guide trunks 216, and the fourth guide bars 214 connecting 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 provided on the first side of the reference line 40 of the first plate 10, and one first flow guide group 110 is provided on the second side of the reference line 40 of the first plate 10, with the two first flow guide groups 110 being symmetrically arranged about the reference line 40. By providing at least two first flow guide groups 110 on the first surface of the first plate 10, the number of contact points can be increased, which is conducive to improving the turbulence of the fluid, thereby improving the heat exchange efficiency of the first plate 10. Furthermore, since the first surface of the first plate 10 is provided with at least two first flow guide trunks 116, the strength of the first plate 10 is enhanced.

[0094] For another example, one second flow guide group 210 is provided on the first side of the reference line 40 of the second plate 20, and one second flow guide group 210 is provided on the second side of the reference line 40 of the second plate 20, with the two second flow guide groups 210 being symmetrically arranged about the reference line 40. By providing at least two second flow guide groups 210 on the first surface of the second plate 20, the number of contact points can be increased, which is conducive to improving the turbulence of the fluid, thereby improving the heat exchange efficiency of the second plate 20. At the same time, since the first surface of the second plate 20 is provided with at least two second flow guide trunks 216, 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 contact, and the first guide group 110 intersects with the corresponding second guide group 210, thereby forming multiple 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 vortexes 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 on the battery, thereby realizing rapid and accurate temperature regulation of the battery, and extending the service life of the battery.

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

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

[0098] In one embodiment, Figure 12 、 Figure 13 and Figure 14 As shown, the first guide bars 112 connecting the corresponding first guide trunks 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 connecting the corresponding first guide trunks 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 connecting the corresponding second guide trunks 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 connecting the corresponding second guide trunks 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, the first guide bars 112 connecting the corresponding first guide trunks 116 can be arranged at equal intervals, and the second guide bars 114 connecting the corresponding first guide trunks 116 can be arranged at equal intervals. By setting the first interval to be greater than or less than the second interval, the flow channel 30 on one side of the first guide trunk 116 can be narrower, while the flow channel 30 on the other side of the first guide trunk 116 can be wider. The third guide bars 212 connecting the corresponding second guide trunks 216 can be arranged at equal intervals, and the fourth guide bars 214 connecting the corresponding second guide trunks 216 can be arranged at equal intervals. By setting the third interval to be greater than or less than the fourth interval, the flow channel 30 on one side of the second guide trunk 216 can be narrower, while the flow channel 30 on the other side of the second guide trunk 216 can be wider. 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, the turbulence of the fluid is improved, and it is beneficial 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, Figure 15 、 Figure 16 and Figure 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; adjacent first guide branches 118 form a seventh preset angle, and 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 provided between two adjacent third guide bars 212 connecting the corresponding second guide trunk 216; at least one fourth guide branch 222 is provided between two adjacent fourth guide bars 214 connecting the corresponding second guide trunk 216; adjacent third guide branches 218 form a ninth preset angle, and adjacent fourth guide branches 222 form a tenth preset angle; 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] The first guide branch 118, the second guide branch 122, the third guide branch 218, and the fourth guide branch 222 can be linear ribs. The first guide branch 118, the second guide branch 122, the third guide branch 218, and the fourth guide branch 222 can be integrally formed with the first plate 10. 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°; and 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 guiding branch 118 and the first guiding trunk 116 can be set to 2 mm, the minimum distance between the second guiding branch 122 and the first guiding trunk 116 can be set to 0.5 mm, the minimum distance between the third guiding branch 218 and the second guiding trunk 216 can be set to 2 mm, and the minimum distance between the fourth guiding branch 222 and the second guiding trunk 216 can be set to 0.5 mm. The spacing between two adjacent first guiding branches 118 ranges from 4 to 16 mm; the spacing between two adjacent second guiding branches 122 ranges from 4 to 16 mm; the spacing between two adjacent third guiding branches 218 ranges from 4 to 16 mm; and the spacing between two adjacent fourth guiding branches 222 ranges from 4 to 16 mm.

[0104] By setting a first guide branch 118 and a second guide branch 122 on the first surface of the first plate 10, and setting a third guide branch 218 and a 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 flow crosswise 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 achieving rapid and accurate temperature regulation of the battery and extending the service life of the battery.

[0105] In one embodiment, Figure 18 、 Figure 19 and Figure 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 formed between the corresponding first guide bar 112 and the third guide bar 212, and another flow channel 30 is formed 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 and making the fluid flow evenly in each flow channel 30. The fluid performs heat exchange on the battery, thereby realizing rapid and accurate temperature regulation of the battery, thereby extending the service life of the battery.

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

[0108] The first diverter strip 124 and the second diverter strip 224 can be long, curved ribs. By arranging the first diverter strip 124 between two adjacent first openings 126, the fluid input to the first opening 126 can be diverted and transmitted. The first diverter strip 124 can divide the flow channel 30 between two adjacent first guide strips 112 into two corresponding sub-flow channels, and the flow channel 30 between two adjacent second guide strips 114 into two corresponding sub-flow channels. By arranging the second diverter strip 224 between two adjacent second openings 226, the fluid input to the second opening 226 can be diverted and transmitted. The second diverter strip 224 can divide the flow channel 30 between two adjacent third guide strips 212 into two corresponding sub-flow channels, and the flow channel 30 between two adjacent fourth guide 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 with each other, the second guide bar 114 and the corresponding fourth guide bar 214 can be stacked in abutment with each other, the first diverter bar 124 and the corresponding second diverter bar 224 can be stacked in abutment with each other, and 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 flows into the second through hole by 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 area, and then the fluid performs efficient heat exchange with the battery, realizes rapid and accurate temperature regulation of the battery, and extends 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.

[0111] In one embodiment, Figure 21 、 Figure 22 and Figure 23 As shown, at least one first protrusion 128 is provided between two adjacent first guide bars 112 , at least one second protrusion 132 is provided between two adjacent second guide bars 114 ; at least one third protrusion 228 is provided between two adjacent third guide bars 212 , and at least one fourth protrusion 232 is provided between two adjacent fourth guide bars 214 .

[0112] Among them, the first protrusion 128 can be but not limited to a truncated cone, a trapezoidal or a prismatic shape; the second protrusion 132 can be but not limited to a truncated cone, a trapezoidal or a prismatic shape; the third protrusion 228 can be but not limited to a truncated cone, a trapezoidal or a prismatic shape; the fourth protrusion 232 can be but not limited to a truncated cone, a trapezoidal or a prismatic shape.

[0113] By arranging a first protrusion 128 between adjacent first guide bars 112, a second protrusion 132 between adjacent second guide bars 114, a third protrusion 228 between adjacent third guide bars 212, and a fourth protrusion 232 between adjacent fourth guide bars 214, the fluid can be cross-diverted when passing through the protrusions, thereby achieving more uniform fluid distribution, further enhancing the eddy current intensity, and improving the heat exchange performance of the plate.

[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 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.

[0116] A side surface of the battery is attached 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 accommodating 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 accommodating 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 to 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 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. 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.

[0118] The technical features of the above embodiments can be combined arbitrarily.
