The invention discloses a hydraulic system with excellent heat dissipation performance and an emergency drainage vehicle. The hydraulic system comprises a hydraulic oil tank; a variable pump; an engine; a reversing valve; the inlet of the multi-way reversing valve is communicated with the first outlet of the reversing valve, and the outlet of the multi-way reversing valve is communicated with the inlet of each actuating mechanism; an outlet of each executing mechanism is communicated with an inlet of the radiator through a multi-way reversing valve, and an outlet of the radiator is communicated with the hydraulic oil tank; the oil return pipeline is arranged in the drainage pipe, a second outlet of the reversing valve is communicated with an inlet of the execution element, an outlet of the execution element is communicated with one end of the oil return pipeline, and the other end of the oil return pipeline is communicated with an inlet of the radiator; an inlet of the switch valve is communicated with an outlet of the execution element, and an outlet of the switch valve is communicated with the hydraulic oil tank. The temperature of the hydraulic oil can be in the optimal working temperature range, and various hydraulic system problems caused by the fact that the temperature of the hydraulic oil is too high or too low are avoided.
