The invention relates to the technical field of hydraulic heat dissipation, in particular to a heat dissipation system and engineering machinery, the heat dissipation system is used for dissipating heat of a driving system, the heat dissipation system comprises a radiator, a cooling liquid outlet is connected with a liquid inlet of a flushing valve group of the driving system; the hydraulic pump is used for conveying working liquid to the radiator when target conditions are met; the heat dissipation system further comprises a liquid storage tank which stores cooling liquid; and the pump assembly is used for conveying the cooling liquid in the liquid storage tank into the radiator. According to the heat dissipation system, the pump assembly sucks the cooling liquid stored in the liquid storage tank, the cooling liquid conveyed by the pump assembly and the working liquid conveyed by the hydraulic pump enter the radiator, the flow of the liquid entering the radiator is increased, then the purpose of improving the heat dissipation efficiency of the driving system is achieved, the output power of the hydraulic pump is not changed, and the service life of the driving system is prolonged. The energy consumption of the whole machine is reduced, and the endurance time of engineering machinery is prolonged.
