具体实施方式
为使本公开解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本发明实施例的技术方案作进一步的详细描述，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。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
如图1～15所示，于本实施例中，一种高性能热管理动力电池模组，包括若 干交错排布的电芯100、热传导模块、液冷模块以及用于固定电芯100的电芯固定模块。所述电芯固定模块包括电芯限位装置以及位于所述电芯限位装置两侧的模组支撑装置300。所述液冷模块集成在所述模组支撑装置300中，所述热传导模块同时与所述电芯100以及所述模组支撑装置300接触。
本方案中根据热传导模块的厚度将电芯100交错排列，固定在电芯固定模块中，并通过热传导模块将热量传递至模组支撑装置300，并由集成在所述模组支撑装置300上的液冷模块将热量带走，从而降低电芯100的温度，同时利用热传导模块的高导热性，使同一排的电芯100温度被拉平，提高电芯100温度的一致性。
通过液冷模块的集成与热传导模块的使用，以及模组的合理设计，确定了电芯100之间的排布方式，去除电芯100之间的冷却水管，从而缩小了电芯100之间的间隔距离，在单位体积内可以布置更多的电芯100，降低了系统的重量，提高了液冷系统的比能量，提高车辆的续航里程。同时将液冷模块布置在两侧，减少水管的实际长度，降低了因液冷模块带来的渗漏的风险，提高系统的可靠性能。采用合理的导热材料的排布方式，将电芯100进行隔绝，避免电芯100热失控的连锁反应，提高系统的使用安全性。
本实施例中所述模组支撑装置300具有空心腔体200，所述空心腔体200的侧壁上设置有进水口以及出水口，所述进水口与所述出水口处设置有管接头500，所述空心腔体200与所述管接头500组成所述液冷模块。
可选地，所述空心腔体200内设置有若干腔体补强件201，所述腔体补强件201相互平行设置，两端分别连接所述空心腔体200的内壁。所述模组支撑装置300具有装置本体310以及支撑连接板320，所述空心腔体200设置在所述装置本体310内部，所述支撑连接板320位于所述装置本体310远离所述电芯100的一侧 与所述装置本体310固定连接，所述支撑连接板320上设置有若干箱体连接孔321。
所述模组支撑装置300采用铝合金材料加工而成，所述空心腔体200以及所述腔体补强件201与装置本体310通过一道生产工序一体成型，在满足冷却需求的同时可以提高整体支架的结构强度，避免在长时间使用的过程中出现疲劳损坏。在一体成型后的铝合金模组支撑装置300的进水口以及出水口处钎焊所述管接头500，本方案中采用汽车级别的快速接头，从而保证系统管路的密封性能与耐久性。最后在支撑连接板320上机加工对应的箱体连接孔321，通过箱体连接孔321以及螺栓将电池模组固定在箱体中。由于此种方式与电池箱体的固定为面接触，确保多个模组固定后的机械强度，增加模组的使用寿命。
所述电芯限位装置包括盖板组件以及支架组件，所述支架组件包括上支架600以及下支架601，所述上支架600与所述下支架601分别设置在所述电芯100的两端，所述盖板组件包括上面盖701以及下面盖700，所述上面盖701位于所述上支架600远离所述电芯100的一侧，所述下面盖700位于所述下支架601远离所述电芯100的一侧。
所述电芯100与所述支架组件通过UV胶水粘结，所述盖板组件以及所述支架组件均采用透明PC材料制成。
本方案中所述电芯限位装置为四层结构，四层结构均采用透明PC材料制成，使用透明PC材料的目的是在使用UV胶水来固定中间的电芯100后，紫外线的照射可以穿过透明PC材料，从而有效的实现胶水的固化，并且可以准确控制固化时间，更利于生产的自动化。通过UV胶水粘结，能够保证更大的机械强度与耐久性，提高产品的可靠性。采用四层结构的目的是将电芯100与上支架600、下之间先通过UV胶水进行固定、从而更好的控制电芯100整体的高度一致性，从而降低底部与顶部的焊接汇流片设备的要求，更快速实现自动化。
所述热传导模块采用导热石墨400制成，其环绕每个所述电芯100并连接成一整体，所述热传导模块的两端分别与所述模组支撑装置300接触。
在采用液冷方式的电池热管理系统中，将电芯100产生的热量带走的方式是系统设计的关键，本实施例的高性能的热管理系统中，采用具有高导热性能的石墨复合材料作为其中的传热介质，将材料环绕电芯100四周并粘接在电芯100表面，利用其高导热性将电芯100产生的热量传导到两侧的模组支撑装置300上，从而将热量带走，并起到一个电芯100之间的均温作用。由于所使用的材料的绝缘性能，通过环绕方式将电芯100与电芯100彻底隔绝，从而在单颗电芯100发生热失控后与其他电芯100隔绝开，形成一个屏蔽，避免电芯100直接接触从而导致连锁反应，发生系统热失控，增加热管理系统的安全性与可靠性。
所述装置本体310上朝向所述上支架600以及所述下支架601的表面分别设置有限位凸起312，所述上支架600以及所述下支架601上与所述限位凸起312对应的设置有限位凹槽311，所述装置本体310通过所述限位凸起312以及所述限位凹槽311卡接在所述上支架600与所述下支架601之间。
可选地，所述上支架600以及所述下支架601上对称的设置有第一电芯安装孔602，所述电芯100的两端分别穿过所述第一电芯安装孔602固定安装在所述上支架600以及所述下支架601中。所述上面盖701以及所述下面盖700上分别设置有第二电芯安装孔702，所述第二电芯安装孔702为沉头孔，所述电芯100穿过所述第一电芯安装孔602的端部位于所述沉头孔中。
