The invention discloses an integrated heat management device of a battery pack circuit breaking unit, which comprises a battery pack cooling pipeline, and the battery pack cooling pipeline at least comprises a first cooling loop and a second cooling loop which are arranged side by side, the first cooling loop and the second cooling loop extend in the arrangement direction of components in the battery pack circuit breaking unit, and the flow directions of refrigerants in the first cooling loop and the second cooling loop are opposite; by arranging the reverse cooling double pipelines, each component in the battery pack circuit breaking unit can be effectively cooled, so that the cooling efficiency of the battery pack circuit breaking unit is improved, and the problem that heating components arranged at the rear half section of a single one-way cooling pipeline cannot be well cooled is avoided.

    本发明公开了一种电池包断路单元的集成热管理装置,其包括电池包冷却管路,所述电池包冷却管路至少包括并排设置的第一冷却回路和第二冷却回路,所述第一冷却回路和第二冷却回路均沿电池包断路单元中元器件的布置方向延伸设置,且所述第一冷却回路和第二冷却回路中的冷媒流向相反;通过设置反向冷却双管道,使电池包断路单元中各个元器件均能够得到有效降温,从而提高电池包断路单元的冷却效率,避免设置在单条单向冷却管道后半段的发热元器件无法得到良好冷却的问题。
