Abstract

本发明提供一种新能源汽车用双温区紧凑型电储热装置，包括由内而外依次包裹的高温换热机构、高温隔热层、低温换热机构以及外保温层，所述高温换热机构包括若干圆柱状封装的高温相变材料单元、多孔介质强化传热材料、液体分布器以及泵驱气液两相循环系统，每根高温相变材料单元外包覆封装外壳，在封装外壳外包裹电加热层，若干高温相变材料单元阵列布置在多孔介质强化传热材料中。对于采用高温金属相变材料的高温换热机构，在充热阶段，利用低谷期的廉价电力通过内置于装置内的电加热套，将电能转化为热能，并储存在高温金属相变材料中。在放热阶段，利用液体分布器喷淋喷雾配合多孔介质强化传热材料增大换热面积，加强换热效率。
