The utility model relates to the technical field of converters, in particular to a power unit, a heat dissipation device based on an electric power electronic power module and an energy storage converter. The 2M power devices are arranged in the M packaging modules respectively, so that the power devices are arranged in a scattered manner; because each packaging module comprises two power deviceswhich are complementary and conducted, namely when the packaged power unit is at any working moment, at most one power device in each packaging module emits heat, and the power devices are not liableto be damaged. The two power devices in each packaging module are heated in a time-sharing manner, and the position of each packaging module is not seriously heated, so that the power units are balanced in heating, and the heating degree of the power units is reduced compared with that of the prior art. 本实用新型涉及变换器技术领域，特别是涉及功率单元、基于电力电子功率模块的散热装置和储能变流器。由于本申请将2M个功率器件分别设置在M个封装模块内，使得各个功率器件分散设置；又由于本申请中的每个封装模块均包括两个互补导通的功率器件，即本申请中封
