储能系统散热装置及储能系统散热方法
本申请要求在2021年02月02日提交中国专利局、申请号为202110145288.1的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于储能技术领域，例如涉及一种储能系统散热装置及储能系统散热方法。
背景技术
集装箱储能系统主要由集装箱式机房、电池包、电池管理系统(Battery Management System，BMS)、储能变流系统(Power Conversion System，PCS)以及辅助控制系统等组成，辅助控制系统大多为温控系统和消防系统等。集装箱储能系统具有占地面积小、安装运输方便、建设周期短、环境适应能力强和智能化程度高等优点，集装箱储能系统可用于联网型微电网、独立型微电网、分布式发电和智能电网等场景，为实现风、光等可再生能源的规模化应用提供有力支撑，同时，集装箱储能系统亦可作为移动应急电源使用。
由于实际工况的复杂不确定性，处于工作状态的多个单体电池必然存在差距，故很难保证电池的工作温度的一致性。若多个电池之间的温度差距加剧，会影响电池模块的性能和使用寿命，甚至引起安全隐患。
CN109638379A公开了一种储能模组用逆流式双风道冷却系统，该系统包括箱体、抽风装置、储能模组和散热装置，抽风装置、储能模组和散热装置设置在所述箱体内，储能模组设置在散热装置上；箱体设有进风口和出风口，储能模组包括多个单体电芯，两两单体电芯之间设有缝隙，缝隙形成供空气流动的第一风道，第一风道与箱体的进风口以及箱体的出风口相连通；散热装置内部设有与第一风道空气流动逆向的第二风道，第二风道与箱体的进风口以及箱体的出风口相连通，通过第一风道和第二风道形成逆流式双风道冷却系统。在该申请中，通过逆流式双风道对储能模块进行冷却，具有均温效果好的特点，但是，该冷却系统不能保证对不同工作状态下的电芯进行温度均一性调控。
CN109037542A公开了一种散热优良的移动储能电池柜，该电池柜包括柜体、底座和储液箱；柜体设置在底座的上方，且柜体与底座的连接处设置有一块隔热板；储液箱固定于底座的下部；柜体与底座的右侧通过进液管相互连通，柜体与底座的左侧通过出液管相互连通。该申请通过泵体将储液箱内部的冷却液抽取送入柜体内部的多个冷却管路，利用铝制的冷却管路将柜体内部的热量 快速吸收，并将热量传递至冷却管路内部流经的冷却液，从而实现柜体的快速冷却，散热效率高。该电池柜依然存在电池温度均一性差的问题。
CN111029496A公开了一种可高效散热的储能电池散热支架，该散热支架包括支架本体、强制通风模块、水冷散热底盘模块和流场控制装置模块，强制通风模块包括至少一个通风管道、进风口和出风口，在每个通风管道内连接一个所述流场控制装置模块；水冷散热底盘模块设在支架本体的底部。该散热支架上综合了风冷和水冷两种冷却模式，冷却效果提升，且将通风管道与支架本体一体化，不需再另设风道，但是该散热支架的结构复杂。
散热装置存在结构复杂、适应性差和电池温度均一性差等问题，因此，如何在保证散热装置具有结构简单的情况下，还能够保证储能模块内电池温度的均一性以及适应性强，成为迫切需要解决的问题。
