The invention provides a thermal management system, an electric driving system and an electric working machine. The thermal management system comprises a box body, a thermal fluid circulation pipeline and a cold fluid circulation pipeline. In the operation process, the heat exchange fluid medium in the box body circularly flows through the cold fluid circulation pipeline. In the process that the heat exchange fluid medium circularly flows in the cold fluid circulation pipeline, the heat exchange fluid medium cools the heating element. And meanwhile, the heat exchange fluid medium in the box body circularly flows through the hot fluid circulating pipeline. And in the process that the heat exchange medium fluid circularly flows in the hot fluid circulation pipeline, the cooling device cools the heat exchange fluid medium. According to the heat management system provided by the invention, the hot fluid circulation pipeline is used for circularly cooling the heat exchange fluid medium in the box body, and the cooled heat exchange fluid medium cools a heating element of the operation machine through the cold fluid circulation pipeline.
本发明提供一种热管理系统、电驱动系统和电动作业机械,该热管理系统包括箱体、热流体循环管路和冷流体循环管路。在运行过程中,箱体内的换热流体介质经冷流体循环管路循环流动。在换热流体介质在冷流体循环管路内循环流动的过程中,换热流体介质对发热元件降温。与此同时,箱体内的换热流体介质通过热流体循环管路循环流动。在换热介质流体在热流体循环管路内循环流动的过程中,冷却装置对换热流体介质进行降温。本发明提供的热管理系统,热流体循环管路用于对箱体内的换热流体介质循环降温,降温后的换热流体介质经冷流体循环管路对作业机械的发热元件进行降温。
