Description

具有热超导换热器的动力电池包及动力电池包系统 技术领域
本发明属于半导体制造技术领域，特别是涉及一种具有热超导换热器的动力电池包及动力电池包系统。
背景技术
随着时代的发展，全球已然掀起一波新能源汽车(电动汽车)的浪潮，同时也加速了电动汽车替代传统燃油车的步伐。最核心的部件就是动力电池。新能源电动汽车最核心部分是由一个或多个动力电池包所组成，而动力电池包是由多个电池单体密集摆放，当电动汽车持续在大负载条件下运行时,动力电池将持续处于大倍率放电状态。此时,电池包内迅速产生大量热量,中间区域必然热量聚集较多，边缘区域较少而增加了电池包中各单体电池温度的不均衡，最终影响整个电池包的性能。当中间区域的热量不能及时快速有效地散热，电池温度会显著升高而导致内部热点，就有可能导致电池热失控、电解液氧化燃烧、甚至爆炸现象的发生。
电池包的设计既要密封、防水、防尘、绝缘等，又要考虑均匀散热。电池包的散热已成为业内研究的一个重要领域。动力电池包的散热通常采用直接风冷散热和液冷散热两种方式。采用风冷就是冷空气直接通过电池单体带走热量，其主要优点有：结构简单，质量轻，有害气体产生时能有效通风，成本较低；不足之处在于：与电池壁面之间换热系数低，冷却速度慢，效率低，且电池间距大，体积大等。采用液冷散热方式通常是用液冷板放在电池底部或用微通道设置与电池单体之间，通过液体流动带走热量。液冷的主要优点有：与电池壁面之间换热系数高，冷却速度快；不足之处在于：密封性要求高，质量相对较大，维修和保养复杂，需要水套、换热器等部件，结构相对复杂。

作为示例，所述热超导板113采用热超导传热技术实现所述电池单体12与所述散热器111及所述加热器112的热交换，这里需要说明的是，所述热超导传热技术包括在密闭的相互连通的微槽道系统内充装工作介质，通过工作介质的蒸发与冷凝相变实现热超导传热的热管技术；以及通过控制密闭体系中工作介质微结构状态，即在传热过程中，液态介质的沸腾(或气态介质的冷凝)被抑制，并在此基础上达到工质微结构的一致性，而实现高效传热的相变抑制(PCI)传热技术。
作为示例，所述传热工质1137为流体，优选地，所述传热工质1137可以为气体或液体或气体与液体的混合物，更为优选地，本实施例中，所述传热工质1137为液体与气体的混合物。

作为示例，在该示例中，所述散热器111还包括散热翅片1114，所述散热翅片1114设置于所述冷却板1111上。优选地，所述散热翅片1114垂直插设于所述冷却板1111远离所述热超导板113的表面上，且所述散热翅片1114与所述冷却板1111的表面相垂直。所述散热翅片1114的数量可以为多个，多个所述散热翅片1114平行间隔分布。

作为示例，如图4及图5所示，所述热超导板1313包括波浪部1131及弯折部1132；其中，所述波浪部1131包括相对的第一表面及第二表面，所述波浪部1131还包括若干个向第一表面凸起的第一凸起部11311及向第二表面凸起的第二凸起部11312，所述第一凸起部11311与所述第二凸起部11312沿所述热超导板113的长度方向依次交替分布且连接为一体；所述弯折部1132位于所述波浪部1131的两端，且与所述波浪部1131的两端相连接；具体的，所述弯折部1132的数量为两个，一个所述弯折部1132位于所述波浪部1131的一端，且与所述波浪部1131的该端连接为一体结构，另一个所述弯折部1132位于所述波浪部1131的另一端，且与所述波浪部1131的该端连接为一体结构；各所述热超导板113经由所述弯折部1132 分别与所述散热器111的表面及所述加热器112的表面相连接(当所述散热器111包括所述冷却板1111时，所述弯折部1132与所述冷却板1111的表面相连接，当所述散热器111包括所述固定基板1115及所述散热翅片1114时，所述弯折部1132与所述固定基板1115远离所述散热翅片1114的表面相连接)；所述电池单体12位于所述波浪部1131的第一表面一侧及第二表面一侧；且位于所述波浪部1131第一表面一侧的所述电池单体12与所述第二凸起部11312对应设置，且贴置于所述第二凸起部11312，位于所述波浪部1131第二表面一侧的所述电池单体12与所述第一凸起部11311对应设置，且贴置于所述第一凸起部11311。
作为示例，所述第一凸起部11311在向所述波浪部1131的第一表面凸起的同时，在所述波浪部1131的第二表面一侧形成了与凸起相对应的凹槽，所述凹槽作为所述电池单体12的容纳空间；同理，所述第二凸起部11312在向所述波浪部1131的第二表面凸起的同时，在所述波浪部1131的第一表面一侧形成了与凸起相对应的凹槽，所述凹槽同样作为所述电池单体12的容纳空间。
