At the same time, the existing heat dissipation structure is difficult to efficiently dissipate heat for battery modules of different sizes, especially the heat dissipation part and the length of the module are not compatible, and it is impossible to make a set of integrated heat dissipation structures directly applicable to different battery modules or battery pack sizes. For this reason, it is urgent to propose a new technical solution to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0028] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. As mentioned throughout the specification and claims, "including" is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0029] In the invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0030] In the present invention, the inventors found that a single cooling circuit cannot guarantee that each battery cell in the battery module can obtain the same cooling effect, which leads to uneven temperature. In addition, each battery cell with uneven temperature will show different performance during the charging and discharging process, thus affecting the consistency and reliability of the entire battery pack. At the same time, the life of the battery module that is in a state of uneven temperature for a long time will also be greatly affected.

[0031] In order to solve the above problems, the following Figures 1 to 4 The present invention is further described in detail with specific embodiments, and the first direction X, the second direction Y and the third direction Z in the drawings are perpendicular to each other, and the first direction X, the second direction Y and the third direction Z are three directions of a three-dimensional rectangular coordinate system, but are not intended to limit the present invention.

[0032] Example 1

[0033] A temperature control structure, see Figure 1 , including a first temperature control component 1 and a second temperature control component 2 arranged side by side along a second direction Y, the first temperature control component 1 has a plurality of first temperature control channels 10 connected in sequence along a first direction X, and the second temperature control component 2 has a plurality of second temperature control channels 20 connected in sequence along the first direction X, wherein the first temperature control channels 10 and the second temperature control channels 20 are respectively L-shaped, the first temperature control component 1 and the second temperature control component 2 are both winding tubular structures, and in order to make the temperatures of the two components match, the first temperature control channels 10 and the second temperature control channels 20 are staggered and stacked along the second direction Y, and the temperature control routes on the left and right sides can be flexibly moved toward or away from each other at the same time to flexibly adjust the overlapping area of ​​the two components.

[0034] In some embodiments, the relative sliding of the two components can be controlled by mounting the two components on a slide rail.

[0035] Furthermore, the first temperature control component 1 and the second temperature control component 2 may also move toward or in opposite directions along the first direction X to adjust the overlapping area of ​​the two components.

[0036] In some embodiments, at least part or all of the first temperature control channels 10 in the first temperature control component 1 can be set to a J-shape, or at least part or all of the second temperature control channels 20 in the second temperature control component 2 can be set to a J-shape. At the same time, the inlet and outlet of the first temperature control component 1 are located on one side of the second direction Y, and the inlet and outlet of the second temperature control component 2 are located on the other side of the second direction Y. The inlet of the first temperature control component 1 and the outlet of the second temperature control component 2 are located on one side of the first direction X, and the outlet of the first temperature control component 1 and the inlet of the second temperature control component 2 are located on the other side of the first direction X.

[0037] Preferably, the thermal conductivity of the pipe material forming the first temperature control channel 10 and the second temperature control channel 20 is not less than 400 W / m·K, the outer diameter of the pipe is at least 6 mm-12 mm, the thickness of the pipe is at least 0.5 mm-1.5 mm, and the battery can be cooled by flowing ethylene glycol aqueous solution in the pipe.

[0038] Preferably, the first temperature-controlled flow channel 10 has a first section 11 and a second section 12 connected to each other, the first section 11 extends along a first direction X, the second section 12 extends along a second direction Y, the length of the second section 12 can be set as needed, the length of the first section 11 is less than the length of the second section 12, so that the pipeline can be expanded along the left and right sides and can better adapt to various types of batteries.

[0039] Preferably, the second sections 12 of each first temperature control channel 10 are aligned along the first direction X, the length of the second section 12 is at least 5 times the length of the first section 11, the second section 12 is an L-shaped or J-shaped straight long side, the first section 11 is an L-shaped or J-shaped short side, and when the first temperature control channel 10 is set to be J-shaped, the first section 11 is an arc-shaped structure.

[0040] Preferably, the second temperature-controlled flow channel 20 has a first section 21 and a second section 22 connected to each other, the first section 21 extends along the first direction X, and the second section 22 extends along the second direction Y. The length of the second section 22 can be set as needed. The length of the first section 21 is less than the length of the second section 22, so that the pipeline can be expanded along the left and right sides and can better adapt to various types of batteries.

[0041] Preferably, the second sections 22 of each second temperature control channel 20 are aligned along the first direction X, the length of the second section 22 is at least 5 times the length of the first section 21, the second section 22 is an L-shaped or J-shaped straight long side, the first section 21 is an L-shaped or J-shaped short side, and when the second temperature control channel 20 is set to be J-shaped, the first section 21 is an arc-shaped structure.

[0042] Preferably, at least part of the first temperature control component 1 and the second temperature control component 2 have an overlapping area in the second direction Y, or the first temperature control component 1 and the second temperature control component 2 completely overlap, so that the first temperature control component 1 and the second temperature control component 2 have a high overlap. That is, after the left and right water cooling routes move toward each other at the same time, the middle parts will overlap. Assuming the overlap is A, the lower limit range of the overlap is: 0% < A ≤ 20%, and the upper limit range of the overlap is: 80% ≤ A < 100%.

[0043] The liquid in the two components that have been largely overlapped (the overlap degree is 90% to 95% or 95% to 99%) begins to flow at a set temperature and is set as a first state. In the first state, the liquid flows of the internal flowing liquids of the first temperature control component 1 and the second temperature control component 2 have n temperature points respectively, and the liquids in the two components increase in temperature from the inlet to the outlet. The n temperature points of the first temperature control component 1 are TL1, TL2, TL3, TL4, ..., TL (n-3) TL (n-2) TL (n-1) TL n The n temperature points of the second temperature control component 2 are TR1, TR2, TR3, TR4, ..., TR (n-3) ,TR (n-2) ,TR (n-1) ,TR n , satisfying the relationship: TL1+TR n =TL2+TR (n-1) =TL3+TR (n-2) =TL4+TR (n-3) =…=TL (n-3) +TR4=TL (n-2) +TR3=TL (n-1) +TR2=TL n +TR1; so that the temperature at the overlapping position is balanced everywhere, improving the liquid cooling effect of the temperature control structure, and n can be a preset constant and not less than 5.

[0044] Preferably, the number of the first temperature control flow channels 10 is i, and the number of the second temperature control flow channels 20 is j, satisfying the relationship: |ij|≤1. When the number of flow channels of the left and right water cooling routes is the same, since the overlap can be changed, it can ensure compatibility with battery modules of different lengths, that is, compatible with different numbers of battery cells in the length direction, and the number of batteries is 1, 2, 3, ..., (ni), i is a positive integer, and 0≤i≤(n-1). On the basis of this embodiment, considering that the battery module will also show changes in width due to different models, it can be considered that the number of flow channels on the left side is always one more than the number of flow channels on the right side, that is, the number of flow channels on the left side is 1, 2, 3, 4, ..., m+1, and the number of flow channels on the right side is 1, 2, 3, 4, ..., m. Similarly, the flow channel on the right side is always one more than the flow channel on the left side, thereby being compatible with modules of different width sizes. In this way, modules of different lengths and width sizes can be compatible at the same time, and this compatibility can be obtained within a certain range by moving the existing left and right flow channels and setting the left and right flow channels in non-equal quantities, rather than designing only a specific liquid cooling system for a specific model of battery module. Therefore, the temperature control structure of this embodiment has strong versatility, can be used more flexibly, and greatly saves the cost of replacement.

[0071] Preferably, the sixth section 3022 of each sixth temperature control channel 3020 is aligned along the third direction Z, the length of the sixth section 3022 is at least 5 times the length of the fifth section 3021, the sixth section 3022 is an L-shaped or J-shaped straight long side, the fifth section 3021 is an L-shaped or J-shaped short side, and when the sixth temperature control channel 3020 is set to be J-shaped, the fifth section 3021 is an arc-shaped structure.

[0072] Preferably, at least part of the fifth temperature control component 301 and the sixth temperature control component 302 has an overlapping area in the first direction X, or the fifth temperature control component 301 and the sixth temperature control component 302 completely overlap, so that the fifth temperature control component 301 and the sixth temperature control component 302 have a high overlap. That is, after the left and right water cooling routes move toward each other at the same time, the middle parts will overlap. Assuming the overlap is A, the lower limit range of the overlap is: 0% < A ≤ 20%, and the upper limit range of the overlap is: 80% ≤ A < 100%.

[0073] Furthermore, when the liquids in the two components that have been largely overlapped (the overlap degree is 90% to 95% or 95% to 99%) start to flow at the set temperature, the liquid flows of the internal flowing liquids of the fifth temperature control component 301 and the sixth temperature control component 302 have n temperature points respectively, and the liquids in the two components increase in temperature from the inlet to the outlet. The n temperature points of the fifth temperature control component 301 are TL1, TL2, TL3, TL4, ..., TL5, ..., TL6, ..., TL7, ..., TL8, ..., TL9, ..., TL10, ..., TL11, ..., TL12, ..., TL13, ..., TL14, ..., TL15, ..., TL16, ..., TL17, ..., TL18, ..., TL19, ..., TL20, ..., TL21, ..., TL22, ... (n-3) TL (n-2) TL (n-1) TL n The n temperature points of the sixth temperature control component 302 are TR1, TR2, TR3, TR4, ..., TR (n-3) ,TR (n-2) ,TR (n-1) ,TR n , satisfying the relationship:

[0074] TL1+TR n =TL2+TR (n-1) =TL3+TR (n-2) =TL4+TR (n-3) =…=TL (n-3) +TR4=TL (n-2) +TR3=TL (n-1) +TR2=TL n +TR1; so that the temperature at the overlapping position is balanced everywhere, improving the liquid cooling effect of the temperature control structure, and n can be a preset constant and not less than 5.

[0075] Preferably, the number of the fifth temperature control channels 3010 is i, and the number of the sixth temperature control channels 3020 is j, satisfying the relationship: |ij|≤1.

[0076] In some embodiments, the angle between the third temperature control structure 300 and the second direction Y can be an acute angle or an obtuse angle.

[0077] Example 4

[0078] See also Figure 4 A battery module 400 equipped with a temperature control module, wherein the first temperature control structure 100 is installed in the horizontal direction of the battery module 400, and the second temperature control structure 200 and the third temperature control structure 300 are installed on the two sides respectively, so as to realize three-dimensional cooling of the battery.

[0079] By designing the two water inlets and outlets in the water-cooled temperature control module on opposite sides and oppositely designed, the temperature of one water cooling route increases in a clockwise direction, and the temperature of the other water cooling route increases in a counterclockwise direction. Different battery modules or battery packs are dissipated and cooled by the two liquid cooling routes. The liquid cooling routes can ensure good dimensional scalability in both the length and width directions of the battery modules. One set of liquid cooling routes can be used for at least several battery modules or battery packs, instead of only matching one battery module or battery pack in the prior art. The present application can effectively solve the problems of uneven heat dissipation, low efficiency and insufficient safety in the existing battery pack heat dissipation technology.
