The invention provides a blowback fan energy-saving control valve bank and a heat dissipating capacity control method.The blowback fan energy-saving control valve bank comprises an oil inlet valve and an oil outlet valve, an inlet of the oil inlet valve is used for being connected with a hydraulic oil source, and an outlet of the oil inlet valve is connected with an inlet of the oil outlet valve through a hydraulic oil way; a proportional valve is arranged on a hydraulic oil way between an outlet of the oil inlet valve and an inlet of the oil outlet valve; and an outlet of the oil outlet valve is connected with a built-in oil cylinder in the blowback fan through a hydraulic pipeline. The device is small in size and can be conveniently installed and integrated in a hydraulic system; by means of pressure switching adjustment of the oil cylinder arranged in the blowback fan, air volume switching and continuous linear adjustment of the blowback fan are achieved, and the heat dissipating capacity of an engine is e
