The invention relates to a thermal management system, an agricultural machine, a control method and a storage medium. Comprising a motor loop assembly, a four-way valve, a PTC heater, a power battery and a three-way valve, wherein a third port of the four-way valve is connected to an outlet of the motor loop assembly; an inlet of the PTC heater is connected to a second port of the four-way valve; an inlet of the power battery is connected to an outlet of the PTC heater; a three-way valve first port of the three-way valve is communicated with a four-way valve first port of the four-way valve, a four-way valve fourth port of the four-way valve is further communicated with an inlet of the motor loop assembly, a power battery outlet is further connected with a battery radiator, and an outlet of the battery radiator is connected to a three-way valve third port of the three-way valve. The technical problems that waste heat of a motor of an existing electric agricultural machine is wasted, a battery pack is heated only through a PTC heater, and energy consumption is high can be solved.

    本发明涉及一种热管理系统、农用机械、控制方法及存储介质,其中,一种热管理系统,包括电机回路总成、四通阀第三端口连接于电机回路总成的出口的四通阀、入口连接于四通阀的四通阀第二端口的PTC加热器、入口连接于所述PTC加热器出口的动力电池以及三通阀第二端口连通动力电池出口的三通阀,所述三通阀的三通阀第一端口连通所述四通阀的四通阀第一端口,且所述四通阀的四通阀第四端口还连通所述电机回路总成的入口,所述动力电池出口还连接有电池散热器,所述电池散热器的出口连接于所述三通阀的三通阀第三端口。本发明可改善现有的电动农用机械的电机余热存在浪费,且电池包只通过PTC加热器进行加热,能耗较高的技术问题。
