The invention relates to the technical field of power assemblies, and provides a power assembly and engineering machine.The power assembly comprises a plurality of generator sets, each generator set comprises an engine and a generator, and the engines and the generators communicate in a one-to-one correspondence mode; the cooling heat dissipation system comprises a plurality of radiators and at least one expansion water tank, and the expansion water tank is communicated with the at least one radiator and the at least one engine; and the radiators are in one-to-one correspondence with the engines. A plurality of generator sets are arranged, each generator set is composed of an engine and a generator which are relatively small in displacement, and a plurality of radiators small in size are adopted for cooling the engines, so that the size of the radiators is reduced; and the problems of poor production and manufacturing process, poor reliability in use and high failure rate caused by overlarge volume of the radiator are avoided.

    本发明涉及动力总成技术领域,提供一种动力总成及工程机械,其中,动力总成包括多组发电机组,每组发电机组均包括发动机和发电机,且发动机与发电机一一对应连通;冷却散热系统,包括多个散热器以及至少一个膨胀水箱,膨胀水箱与至少一个散热器和至少一个发动机连通;且散热器与发动机一一对应设置。本发明通过设置多组发电机组,每组发电机组由相对较小排量的发动机和发电机组成,而且,采用多个体积较小的散热器分别给发动机散热,减小了散热器的体积,避免了散热器由于体积过大而出现的生产制造工艺差和使用时可靠性差、故障率高的问题。
