技术领域
本发明涉及纯电动汽车电池热管理领域,尤其涉及一种冷热一体式液冷板。
背景技术
纯电动汽车是未来汽车发展的必然趋势,为了提高驾驶舒适度和市场竞争力以及整车电池寿命,为其配套热管理系统是必不可少的。传统燃油汽车空调系统是利用发动机余热供暖,由于纯电动汽车没有发动机,主要能量来源于电池,那么如何制热为纯电动汽车热管理系统带来了新的挑战。锂离电池的最佳温度范围为+20~+30℃。在低温时,锂电池因阳极析锂,导致容量永久性降低。在高温时,活性化学物质可能发生不可逆的反应,从而破坏电池。主要影响:循环寿命、行驶里程、充电时间。目前主要的方案分别为:水加热PTC配合液冷板,给电池提供加热和加热膜。针对上述方案,1.水加热PTC配合液冷板系统复杂成本高,2.加热膜易刺穿,耐电压差,温度易失控,存在漏电起火风险。针对上述问题我们研发了一款冷热一体式液冷板。

进一步改进在于:所述PTC发热芯体外设置有外壳,外壳设置在上平板底部,外壳位于接电线一端是开口的。
进一步改进在于:所述蛇形的流道下表面分布蛇形排列的向上凹的凹陷。
进一步改进在于:所述上平板位于接电线一端往侧面伸出有两个带有安装孔的固定臂。
