The invention provides a thermal management system and engineering machinery, and the thermal management system comprises a first refrigerant loop which comprises an evaporator, a first expansion valve, a first heat exchanger and a compressor which are connected in sequence; the motor loop, the battery loop and the heat exchange pipeline are used for guiding cooling liquid, the motor loop and the battery loop are connected in parallel to form a heat supply source, a first warm core body is arranged on the heat exchange pipeline, and the two ends of the heat exchange pipeline are connected with the heat supply source; when flowing through the first heat exchanger, a refrigerant in the first refrigerant loop absorbs heat, capable of exchanging heat with the first heat exchanger, in hydraulic oil, the refrigerant absorbing the heat is compressed through the compressor and then transferred into the evaporator, and the evaporator dissipates the heat carried by the refrigerant into a cab. Heat absorbed by cooling liquid in the motor loop flowing through the motor and heat absorbed by cooling liquid in the battery loop flowing through the battery are transferred to the first warm core body through the heat exchange pipeline, and the heat carried by the cooling liquid is dissipated into a cab through the first warm core body.
