背景技术Background technique
电池系统是由众多电池组成，在使用过程中会产生很多热量，由于各个电池在电池系统中的位置不同引起其散热能力的不同，从而使电池系统中各个电池的温度存在很大差异，这个差异使得电池使用过程中的性能不一致，从而降低系统的使用效率，严重的会影响电池的使用寿命。The battery system is composed of many batteries, which will generate a lot of heat during use. Due to the different positions of each battery in the battery system, the heat dissipation capacity is different, so that the temperature of each battery in the battery system is very different. This difference The performance of the battery during use is inconsistent, thereby reducing the efficiency of the system, and seriously affecting the service life of the battery.
现行的解决方案是对电池系统进行风冷或液冷，风冷由于其导热性能差，难以有效的平衡电池系统的温差。对于有更高要求的电池系统往往采用液冷方式。但是现有的液冷方案仍有诸多不足，例如，由于液冷装置中的流道大小是一致的，因此液冷装置对电池系统中各个电池的冷却能力是一致的，不能对电池系统中不同温度的电池进行差异化管理，仍很难将电池系统中各个电池的温差控制在很小的范围，造成系统的使用效率低，影响电池的使用寿命。The current solution is to air-cool or liquid-cool the battery system. Due to its poor thermal conductivity, air-cooling is difficult to effectively balance the temperature difference of the battery system. For battery systems with higher requirements, liquid cooling is often used. However, there are still many deficiencies in the existing liquid cooling schemes. For example, since the flow channels in the liquid cooling device are of the same size, the cooling capacity of the liquid cooling device for each battery in the battery system is consistent, and it cannot be used for different battery systems in the battery system. It is still difficult to control the temperature difference of each battery in the battery system within a small range, resulting in low efficiency of the system and affecting the service life of the battery.

具体实施方式detailed description
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.
第一方面，本发明实施例提供一种电池液冷装置，如图1～3所示，该装置包括液冷板1以及设置在所述液冷板1上的流道流量调节部件，其中：In the first aspect, an embodiment of the present invention provides a battery liquid cooling device. As shown in FIGS. 1 to 3 , the device includes a liquid cooling plate 1 and a channel flow regulating component arranged on the liquid cooling plate 1 , wherein:
所述液冷板1包括板壳14和设置在板壳14内部的冷却液流道；The liquid cold plate 1 includes a plate shell 14 and a cooling liquid flow channel arranged inside the plate shell 14;
所述流道流量调节部件的制作材料中包括形状记忆材料，用于接触电池3并根据所接触电池3的表面温度调节所述冷却液流道的流量大小。The manufacturing material of the channel flow regulating component includes a shape memory material, which is used to contact the battery 3 and adjust the flow rate of the cooling liquid channel according to the surface temperature of the contacted battery 3 .
可理解的是，由于流道流量调节部件由形状记忆材料制成，其根据温度调节所述冷却液流道的流量大小的过程实际上是形状记忆材料的形变过程，形状记忆材料的形变导致冷却液流道的流量大小发生变化。It can be understood that since the channel flow regulating component is made of shape memory material, the process of adjusting the flow rate of the coolant channel according to the temperature is actually a deformation process of the shape memory material, and the deformation of the shape memory material leads to cooling The flow rate of the liquid channel changes.
举例来说，当流道流量调节部件接触到的电池3的表面温度比较低，低于形状记忆材料的形变温度时，形状记忆材料的形变导致冷却液流道的流量较小，此时的冷却效果较低。当流道流量调节部件接触到的电池3的表面温度升高至高于形状记忆材料的形变温度时，形状记忆材料的形变导致冷却液流道的流量变大，此时的冷却效果提高。当经较强的冷却后，流道流量调节部件接触到的电池3的表面温度降低至低于形状记忆材料的形变温度时，形状记忆材料的形变导致冷却液流道的流量变小，使冷却强度处于比较低的状态。For example, when the surface temperature of the battery 3 contacted by the flow channel flow adjustment component is relatively low, lower than the deformation temperature of the shape memory material, the deformation of the shape memory material will cause the flow rate of the cooling liquid channel to be small, and the cooling at this time less effective. When the surface temperature of the battery 3 contacted by the channel flow adjustment member rises above the deformation temperature of the shape memory material, the deformation of the shape memory material will cause the flow rate of the coolant channel to increase, and the cooling effect at this time will be improved. After stronger cooling, when the surface temperature of the battery 3 contacted by the flow channel flow adjustment component is lowered to lower than the deformation temperature of the shape memory material, the deformation of the shape memory material will cause the flow rate of the coolant flow channel to decrease, making the cooling Intensity is relatively low.
本发明提供的电池液冷装置中包括流道流量调节部件，该流量调节部件由形状记忆材料制成，温度的变化会导致流道流量调节部件的形变，从而引起冷却液流道的流量大小的变化，实现冷却强度自动调节的功能。由于本发明提供的电池液冷装置能够根据流道流量调节部件接触到的电池3的表面温度自动调节冷却强度，对于不同的电池3，与其接触的流道流量调节部件的形变量不同，所以液冷装置对于不同的电池3的冷却能力是不同的，可以实现对不同温度的电池3的差异化管理，从而将各个电池3的温差控制在很小的范围，提高电池3的使用效率，延长电池3的使用寿命。The battery liquid cooling device provided by the present invention includes a flow channel flow regulating part, which is made of a shape memory material. Changes in temperature will cause deformation of the flow channel flow regulating part, thereby causing a change in the flow rate of the cooling liquid channel. Changes to realize the function of automatic adjustment of cooling intensity. Since the battery liquid cooling device provided by the present invention can automatically adjust the cooling intensity according to the surface temperature of the battery 3 in contact with the flow channel flow regulating component, for different batteries 3, the deformation of the flow channel flow regulating component in contact with it is different, so the liquid The cooling capacity of the cooling device is different for different batteries 3, which can realize differentiated management of batteries 3 at different temperatures, thereby controlling the temperature difference of each battery 3 within a small range, improving the use efficiency of batteries 3, and prolonging battery life. 3 service life.
在具体实施时，所述流道流量调节部件可以采用多种结构形式实现，对此本发明不做限定。如图1～3所示，其中一种可选的结构为：In a specific implementation, the flow channel flow adjustment component can be implemented in various structural forms, which is not limited in the present invention. As shown in Figures 1 to 3, one of the optional structures is:
所述流道流量调节部件包括接触部21和截流部22，其中：The flow channel flow adjustment component includes a contact part 21 and a cut-off part 22, wherein:
所述接触部21，设置在所述板壳14外部，且穿过所述板壳14与所述板壳14内部的截流部22连接，用于接触所述板壳14外部的电池3；The contact portion 21 is arranged outside the plate case 14 and passes through the plate case 14 to connect with the cut-off portion 22 inside the plate case 14 for contacting the battery 3 outside the plate case 14;
所述截流部22，设置在所述板壳14内部的冷却液流道中，用于根据所连接的接触部21接触的电池3的表面温度发生形变以调节所述冷却液流道的流量大小。The cut-off part 22 is arranged in the cooling liquid channel inside the plate shell 14, and is used for adjusting the flow rate of the cooling liquid channel according to the temperature of the battery 3 contacted by the connected contact part 21 to be deformed.
举例来说，当接触部21接触到的电池3的表面温度比较低，低于形状记忆材料的形变温度时，截流部22处于比较舒展的状态，从而使得冷却液流道中可流通冷却液的截面比较小，因此冷却液流道的流量比较小，冷却强度比较低。当接触部21接触到的电池3的表面温度比较高，高于形状记忆材料的形变温度，截流部22收缩，从而使得冷却液流道中可流通冷却液的截面变大，冷却液流道的流量变大，冷却强度提高。当经过较强的冷却后，接触部21所接触的电池3表面温度降低，低于形状记忆材料的形变温度时，截流部22的形变恢复，使得冷却液流道的流量变小，使冷却强度变回比较低的状态。For example, when the surface temperature of the battery 3 contacted by the contact portion 21 is relatively low, lower than the deformation temperature of the shape memory material, the cut-off portion 22 is in a relatively stretched state, so that the cross-section of the cooling liquid can flow through the cooling liquid channel. Relatively small, so the flow rate of the coolant channel is relatively small, and the cooling intensity is relatively low. When the surface temperature of the battery 3 contacted by the contact portion 21 is relatively high, which is higher than the deformation temperature of the shape memory material, the cut-off portion 22 shrinks, so that the cross section through which the cooling liquid can flow in the cooling liquid channel becomes larger, and the flow rate of the cooling liquid channel becomes larger and the cooling intensity increases. After strong cooling, the surface temperature of the battery 3 contacted by the contact part 21 decreases, and when it is lower than the deformation temperature of the shape memory material, the deformation of the cut-off part 22 recovers, so that the flow rate of the cooling liquid channel becomes smaller, and the cooling intensity is reduced. return to a lower state.
在上述结构的流道流量调节部件中，设置在板壳14外部的接触部21用于接触电池3，设置在壳体内部的冷却液流道中的截流部22根据其连接的接触部21所感测到的温度发生形变，以实现对所述冷却液流道的流量大小的调节。该结构的流道流量调节部件结构简单、易实现。In the channel flow regulating part of the above structure, the contact part 21 provided outside the plate case 14 is used to contact the battery 3, and the cut-off part 22 provided in the cooling liquid channel inside the casing is sensed according to the connected contact part 21. deformation at a certain temperature to realize the adjustment of the flow rate of the cooling liquid channel. The flow channel flow regulating part of this structure is simple in structure and easy to realize.
在具体实施时，液冷板1内部的冷却液流道可以采用多种结构形式，对应的截流部22的设置方式也会不同。如图1～3所示，其中冷却液流道的一种可选结构形式为：所述冷却液流道包括主进流通道11、主回流通道12以及连通所述主进流通道11和所述主回流通道12的多个支路通道13。对于这种结构的冷却液流道，可以将截流部22设置在至少一个支路通道13中。In a specific implementation, the cooling liquid channel inside the liquid cooling plate 1 can adopt various structural forms, and the arrangement of the corresponding intercepting portion 22 will also be different. As shown in Figures 1 to 3, an optional structural form of the cooling liquid flow channel is: the cooling liquid flow channel includes a main inflow channel 11, a main return flow channel 12, and the main inflow channel 11 and the A plurality of branch channels 13 of the main return channel 12. For a coolant channel of this configuration, the shut-off 22 can be arranged in at least one branch channel 13 .
在上述结构的冷却液流道中，冷却液从主进流通道11流入，经过支路通道13后，从主回流通道12引出。由于截流部22设置在至少一个支路通道13，因此可以实现对该至少一个支路通道13的流量进行调节。In the cooling liquid channel with the above structure, the cooling liquid flows in from the main inflow channel 11 , passes through the branch channel 13 , and is led out from the main return flow channel 12 . Since the intercepting portion 22 is arranged on at least one branch channel 13 , the flow rate of the at least one branch channel 13 can be adjusted.
在上述结构的冷却液流道中，所述支路通道13可以有多种结构形式实现，例如参考图2，支路通道13由设置在所述主进流通道11和所述主回流通道12之间的多个筋条15形成，当然还可以采用其他结构形式实现。In the coolant channel of the above structure, the branch channel 13 can be realized in various structural forms, for example, referring to FIG. A plurality of ribs 15 between them are formed, of course, other structural forms can also be used to realize.
在具体实施时，上述的形状记忆材料可以采用形状记忆合金，也可以采用热致型形状记忆聚合物，当然还可以采用其他能够因温度而形变的材质，对此本发明不做限定。In specific implementation, the above-mentioned shape memory material can be a shape memory alloy, or a thermotropic shape memory polymer, and of course other materials that can be deformed by temperature can also be used, which is not limited in the present invention.
在具体实施是，上述板壳14可以采用多种制作材料制成，为了使其具有较好的导热性，可以选用金属，例如铜，也可以采用合金，例如铝合金。In a specific implementation, the plate shell 14 can be made of various materials. In order to make it have better thermal conductivity, metals such as copper or alloys can be used, such as aluminum alloy.
第二方面，本发明还提供一种电池系统，包括多个电池3，还包括上述任一电池液冷装置，所述电池液冷装置与各个电池3接触设置。In a second aspect, the present invention also provides a battery system, which includes a plurality of batteries 3 and any battery liquid cooling device described above, and the battery liquid cooling device is arranged in contact with each battery 3 .
可理解的是，由于第二方面提供的电池系统中包括第一方面提供的电池液冷装置，有关内容的解释、举例说明。可选实施方式、有益效果等内容可以参考第一方面提供的电池液冷装置中的相应部分，在此不再赘述。It can be understood that since the battery system provided by the second aspect includes the battery liquid cooling device provided by the first aspect, explanations and examples of relevant contents are provided. For optional implementation manners, beneficial effects, and other content, reference may be made to corresponding parts in the battery liquid cooling device provided in the first aspect, and details are not repeated here.
综上所述：本发明实施例提供的电池液冷装置及电池系统，包括流道流量调节部件，该流量调节部件由形状记忆材料制成，温度的变化会导致流道流量调节部件的形变，从而引起冷却液流道的流量大小的变化，实现冷却强度自动调节的功能。由于本发明实施例提供的电池液冷装置能够根据流道流量调节部件接触到的电池的表面温度自动调节冷却强度，对于不同的电池，与其接触的流道流量调节部件的形变量不同，所以液冷装置对于不同的电池的冷却能力是不同的，可以实现对不同温度的电池的差异化管理，从而将各个电池的温差控制在很小的范围，提高电池的使用效率，延长电池的使用寿命。To sum up: the battery liquid cooling device and the battery system provided by the embodiments of the present invention include a flow channel flow regulating part, which is made of a shape memory material, and changes in temperature will cause deformation of the flow channel flow regulating part. As a result, the flow rate of the coolant channel changes, and the function of automatic adjustment of the cooling intensity is realized. Since the battery liquid cooling device provided by the embodiment of the present invention can automatically adjust the cooling intensity according to the surface temperature of the battery in contact with the flow channel flow adjustment component, for different batteries, the deformation of the flow channel flow adjustment component in contact with it is different, so the liquid The cooling capacity of the cooling device is different for different batteries, which can realize the differentiated management of batteries with different temperatures, so as to control the temperature difference of each battery in a small range, improve the efficiency of battery use, and prolong the service life of batteries.
