Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
The embodiment of the application provides a liquid cooling plate for a battery pack, which can solve the problems of flow non-uniformity and on-way resistance of a cooling plate due to the baffling flow design of a cooling medium in the conventional cooling plate.
Referring to fig. 1 to 5, a liquid cooling plate for a battery pack according to the present embodiment includes a plate body 1, two liquid collecting chambers 5 provided at both ends of the plate body 1, and at least two flow passages 101 provided in the plate body 1 and independently arranged in parallel.
Referring to fig. 1, both ends of the flow channel 101 are respectively connected to the two liquid collecting chambers 5, and the shape of the flow channel 101 is configured to: when the flow direction of the cooling medium is changed, the included angle between the changed direction and the direction before the change is not more than 90 degrees.
When the flowing direction of the cooling medium is changed, if the included angle between the changed direction and the direction before the change is larger than 90 degrees, the cooling medium can be baffled greatly, so that a flowing dead zone is easy to form, the flow distribution is uneven, and the cooling effect is reduced.
Referring to fig. 2, specifically, the flow channel 101 may have a straight line shape, a zigzag shape, or a wavy shape, for example, when the flow channel 101 is provided in a zigzag shape, the angle of each corner of the flow channel 101 is set to be not less than 90 ° so that the angle of each change in the flow direction of the cooling medium is not more than 90 °, and when the flow channel 101 is provided in a wavy shape, the angle of each change in the flow direction of the cooling medium is not more than 90 °.
Through the arrangement, the design of the structure of the flow channel 101 can ensure that the cooling medium does not flow in the flow channel 101 or reduce the flow deflection amplitude, and reduce the dead zone of the cooling medium flow, thereby enhancing the flow uniformity of the cooling medium in the flow channel 101 and improving the cooling effect.
In this embodiment, the plate body 1 has a rectangular parallelepiped shape, and the flow channel 101 extends from one end to the other end of the plate body 1, and is illustrated as a straight line shape of the flow channel 101.
Referring to fig. 2 to 4, further, the number of the flow channels 101 may be set according to the design size thereof and the size of the plate body 1, and the plurality of flow channels 101 may be sequentially arranged along the length direction or the width direction of the plate body 1; when the battery module 2 is connected with the liquid cooling plate, the battery module 2 is attached to one side surface of the liquid cooling plate and is arranged on the liquid cooling plate through the heat conduction structural adhesive 8, so that the contact area between the battery module 2 and the liquid cooling plate is maximized to improve the cooling effect, a plurality of battery modules 2 can be connected to one liquid cooling plate as required, and a plurality of battery modules 2 are cooled through one liquid cooling plate.
Referring to fig. 1, further liquid collecting cavities 5 are disposed at two ends of the plate body 1 and are fixedly connected with the plate body 1, the length of each liquid collecting cavity is rectangular and is consistent with the width of the plate body 1, openings communicated with a plurality of flow channels 101 are formed in one side wall of each liquid collecting cavity 5, the flow channels 101 are all communicated with the openings, wherein a liquid inlet 6 is formed in one liquid collecting cavity 5, and a liquid outlet 7 is formed in the other liquid collecting cavity 5.
Through the arrangement, the two ends of the flow channel 101 are directly communicated with the two liquid collecting cavities 5, so that the length of the flow channel 101 can be obviously shortened, the flow path of a cooling medium is reduced, the flow resistance of the cooling medium is reduced, and the pressure difference between an inlet and an outlet of the liquid cooling plate is reduced.
Further, referring to fig. 2-4, a turbulence assembly for enhancing turbulence of the cooling medium is disposed in the flow channel 101, and a cross-sectional area of the turbulence assembly disposed in at least one flow channel 101 perpendicular to the flow direction of the cooling medium is 30% -70% of the flow cross-sectional area of the flow channel 101 (refer to fig. 4). When the cross section area of the disturbance component is less than 30% of the cross section area of the flow channel 101, the heat exchange effect is poor, and when the cross section area of the disturbance component is more than 70% of the cross section area of the flow channel 101, the pressure of the flow channel 101 is high, so that it is preferable that the cross section area of the disturbance component arranged in at least one flow channel 101 is 40% -60% of the cross section area of the flow channel 101, so that the disturbance component has enough disturbance effect, the heat exchange effect of the cooling medium is improved, and the pressure of the cooling medium in the flow channel 101 is not easy to be excessively high.
Referring to fig. 2-3, further, the projection area of the disturbance component disposed in at least one flow channel 101 on the plane of the plate body 1 accounts for 20% -40% of the projection area of the flow channel 101 on the plane of the plate body 1. This arrangement can further improve the disturbing effect of the disturbing assembly to improve the heat exchanging effect of the cooling medium, and at the same time, the excessive pressure of the cooling medium in the flow passage 101 is not easily caused.
Specifically, the disturbance module includes a plurality of disturbance blade sets 3, and the plurality of disturbance blade sets 3 are distributed along the length direction of the flow channel 101.
Referring to fig. 2-4, the turbulence plate group 3 includes a plurality of turbulence plates 301 distributed along the width direction of the flow channel 101, and the sum of characteristic lengths of the plurality of turbulence plates 301 in the turbulence plate group 3 is smaller than the width of the flow channel 101, so as to ensure that the cooling medium can circulate normally. Correspondingly, the cross section of the disturbance component perpendicular to the flow direction of the cooling medium accounts for the percentage of the flow cross section of the flow channel 101, that is, the percentage of the area of the disturbance piece 301 in the next flow channel 101 to the area of the flow channel 101 in the view of fig. 4; the projected area of the disturbance component disposed in one flow channel 101 on the plane of the plate body 1 is the percentage of the projected area of the flow channel 101 on the plane of the plate body 1, that is, the percentage of the area of all disturbance plates 301 in the flow channel 101 in the view angles of fig. 2 and 3 to the area of the flow channel 101.
Specifically, the shape of the disturbance plate 301 may be a cylindrical shape, a square shape, or an irregular shape, and the disturbance plate 301 may be designed so that disturbance can be generated when the cooling medium flows through the disturbance plate 301.
By arranging the disturbance plate group 3, the disturbance of the cooling medium can be enhanced when the cooling medium flows in the flow channel 101, the heat exchange coefficient is increased, and the heat exchange effect is enhanced.
As shown in fig. 2-3, further, the plurality of disturbance plate groups 3 may be distributed at equal intervals over the flow channel 101, or the intervals between adjacent disturbance plate groups 3 may be gradually decreased in the flow direction of the cooling medium.
Because the temperature difference between the cooling medium at the inlet of the flow channel 101 and the battery module 2 is greater than the temperature difference between the cooling medium at the outlet and the battery module 2, when the battery module 2 adopts an arrangement mode that the distance between adjacent disturbance plates 3 along the flow direction of the cooling medium is gradually reduced, the density of the disturbance plates 301 arranged at the outlet of the flow channel 101 is greater than the density of the inlet, so that the disturbance of the cooling medium at the outlet of the flow channel 101 is more severe, the heat exchange coefficient at the outlet of the flow channel 101 is greater than the heat exchange coefficient at the inlet, the aim of uniform heat exchange of the whole liquid cooling plate is achieved, the consistency of the temperature of the battery cells is improved, and the temperature difference between the battery cells is reduced.
Correspondingly, the liquid collecting cavity 5 with the larger density end of the disturbance piece 301 in the flow channel 101 is the liquid outlet end liquid collecting cavity 5, the liquid outlet 7 is arranged on the liquid collecting cavity, the liquid collecting cavity 5 with the smaller density end of the disturbance piece 301 in the flow channel 101 is the liquid inlet end liquid collecting cavity 5, and the liquid inlet 6 is arranged on the liquid collecting cavity 5.
For the battery module 2 with metal end plates at two ends, as the end plates are metal, the heat exchange coefficient of the end plates is large, so that the heat dissipation of the battery cells at two ends is faster than that of the battery cells in the middle, and the temperature consistency of the battery cells is poor. Therefore, the intercepting members 4 for reducing the heat exchange area of the end portions can be disposed at both ends of the flow channel 101, and the width of the intercepting members 4 is smaller than that of the flow channel 101, so that a fluid-free area is formed in the flow channel 101 at the intercepting members 4, that is, no cooling medium flows in the fluid-free area in the thickness direction of the flow channel 101, the heat exchange area of the end portion of the flow channel 101 can be reduced, that is, the heat exchange area of the end portion of the liquid cooling plate is reduced, the heat exchange between the battery module 2 with the end plate at the end portion and the liquid cooling plate is reduced, the effect of improving the consistency of the temperature of the battery cells is achieved, and the uniformity of the temperature of the battery module 2 is improved.
Referring to fig. 5, in particular, the intercepting member 4 in this embodiment is an intercepting block, whose upper and lower sides are engaged with the upper and lower inner walls of the flow channel 101 and integrally formed with the plate body 1, so as to form a fluid-free region at the end of the flow channel 101; in other embodiments, the fluid-free region may be formed by stamping the plate body 1 at the end of the flow channel 101.
As shown in fig. 5, further, the width of the intercepting member 4 is gradually reduced in a direction away from the end of the flow channel 101, and the intercepting member 4 is provided at the middle of the flow channel 101 in the width direction, even though the fluid-free region is smaller in width as it is farther from the end of the flow channel 101, and the fluid-free region is located at the middle of the flow channel 101 in the width direction, the fluid-free region can be made to function to enhance the disturbance of the cooling medium at the end of the flow channel 101, so as to enhance the heat exchange effect.
The cross section of the flow channel 101 may be circular or polygonal, and is set according to actual needs, and is illustrated as a rectangle in this embodiment.
The tamper strip 301 may be disposed within the flow channel 101 by welding, extrusion, or other integral molding.
The plate body 1 can be made of aluminum alloy or other materials which are easy to process and have large heat conductivity coefficient, and the plate body is selected according to actual needs.
The liquid cooling plate of this embodiment is simple and small, and is simple and convenient with the connection of battery module 2, can integrate in the battery box.
The liquid cooling plate of the embodiment can also be used for heating a module in a battery pack, and the type of medium can be selected according to the requirement.
The implementation principle of the implementation is as follows: the battery pack is arranged on the liquid cooling plate, when the battery pack works, a cooling medium enters the liquid collecting cavity 5 at the inlet end through the liquid inlet 6 and then enters the plurality of flow channels 101, the cooling medium flows in the flow channels 101 and exchanges heat with the plate body 1, and the plate body 1 exchanges heat with the battery pack through the heat conduction structural adhesive 8 to realize cooling of the battery pack; the cooling medium is disturbed when flowing in the disturbance sheet group 3 in the flow channel 101, so that the heat exchange capacity of the cooling medium is enhanced; the cooling medium flows into the liquid collecting cavity 5 at the outlet end after flowing through the flow channel 101 and is discharged from the liquid outlet 7, so that the purpose of cooling the battery module 2 through the liquid cooling plate is achieved; the purpose of heating the battery module 2 can also be achieved by replacing the cooling medium with the heating medium.
