About GFNS3 concrete structure cooling towers of reinforced concrete frame series of energy-efficient counterflow cooling tower is the fourth by the Ministry of Machinery Industry Design and Research Institute of Tsinghua University jointly developed, single-cell water is 800-4000mm / h, a total of nine specifications. It has good thermal performance, low power consumption, good stability of the entire tower, beautiful appearance, low noise, construction and installation period is short, and low cost, widely used in enterprises and large quantity of petroleum, chemical, metallurgy, power generation and other circulatory system in. 1, "energy-efficient cooling tower" (patent number: 95395994.1), which uses a variable torque change pole motor, so that in ensuring the thermal performance of the premise, the annual energy consumption 40 - 50%, ranking the leading domestic and foreign level. 2, the "multi-span continuous beam cantilever main column of reinforced concrete cooling tower" (patent number: 9552355.4), characterized by the outside air inlet of the column to the inside move 1-2.5m, the flow of air directly into the water spray fillers, reducing the inlet vortex beams at the height of the tower and fell 0.5-0.9m. Even with the wind, the cold efficiency improvements. In cold areas, there will no longer reinforced concrete beams, columns thaw damage phenomenon. 3 "square cooling tower with oblique trapezoidal wave filler" (patent number: 9547967.2), characterized by a trapezoidal wave form a ramp by adhesive filler block head, good stability and durability. The trapezoidal wave height 23mm, relying on the mounting head film from 30mm.
