HYDRAULICALLY OPERATED UNIT COOLER DEVICE AND DRIVING METHOD OF THE SAME

摘要

PURPOSE: A hydraulically operated unit cooler device and driving method of the same are provided to reduce consumption of electric energy and manufacturing cost. CONSTITUTION: A hydraulic pressure generating device is installed on the outside of a storehouse and comprises a hydraulic oil storage tank(1), a hydraulic oil pump(2) installed by the hydraulic oil storage tank and a hydraulic pressure control valve(3) installed on a tube. A unit cooler(5) is installed in the storehouse and comprises a hydraulic motor(6) and a cooling fan(7) connected to one end of the hydraulic pump. Hydraulic oil supplied from the hydraulic pressure generating device through the tube drives the hydraulic motor to generate rotary force so as to rotate the cooling fan.
