固態(tài)高頻焊機循環(huán)軟水冷卻系統(tǒng)（風—水冷卻器）

GPKL-Ⅱ型循環(huán)軟水冷卻系統(tǒng)采用閉式冷卻塔結構，冷卻用軟水在密封水箱及冷卻管道中流動，由頂置風機 噴淋水方式冷卻內循環(huán)軟水，其工作原理為:利用水蒸發(fā)時吸收熱量的原理使被冷卻軟水冷卻。噴淋水貯于冷卻塔底部，軟水在閉式冷卻塔的散熱盤管內進行封閉循環(huán)，噴淋水由噴淋系統(tǒng)泵經(jīng)水分配系統(tǒng)和噴淋嘴噴淋在盤管表面，一部分水被蒸發(fā)吸走熱量，從而降低管內軟水的溫度。熱空氣中的水和未蒸發(fā)的水被擋水板截住并流經(jīng)PVC熱交換層，PVC交換層中的水被流過的空氣冷卻，溫度降低，落入冷卻塔底部。

適用范圍：60kW～1200kW感應加熱電源。

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.
