GPKL-Ⅱ型循环软水冷却系统采用闭式冷却塔结构，冷却用软水在密封水箱及冷却管道中流动，由顶置风机 喷淋水方式冷却内循环软水，其工作原理为:利用水蒸发时吸收热量的原理使被冷却软水冷却。喷淋水贮于冷却塔底部，软水在闭式冷却塔的散热盘管内进行封闭循环，喷淋水由喷淋系统泵经水分配系统和喷淋嘴喷淋在盘管表面，一部分水被蒸发吸走热量，从而降低管内软水的温度。热空气中的水和未蒸发的水被挡水板截住并流经PVC热交换层，PVC交换层中的水被流过的空气冷却，温度降低，落入冷却塔底部。

适用范围：60kW～1200kW感应加热电源。

Circulation Soft Water Cooling System (air-water cooler)

Model GPKL-Ⅱcirculation soft water cooling system adopts closed cooling tower structure. Cooling soft water flow in sealed water tank and cooling pipes. The inner circulation soft water is cooled by overhead fan and water-spray method using the principle of absorbing heat when evaporation. The spray water store at the bottom of cooling tower, soft water circulate inside the closed cooling tower’s heat dissipation pipe, spray-water spray at pipes’ surface by spray-water distribution system and sprayer through spray system, some heat is taken by dissipation and soft water temperature inside the pipe go down accordingly. The cut board stops water in hot air and undissipated water, make them flow through PVC heat exchange layer, the water in the layer is cooled by air, then temperature goes down and fall down to the bottom of the tower.

Apply range: 60kW～1200kW induction heating power supply.
