運作原理 |
|
壓縮空氣, 通常在80到100 PSlG,從側邊進入管中,經過generator引起空氣渦漩。 空氣流經過導流葉片,從管內外部,流向熱氣控制閥然後排出熱氣,冷空氣則在中心形成另一渦漩,由另一端排出。因此,將壓縮空氣,分為冷熱兩端排出。 並且不需使用任何電力。
Nex FlowTM Frigid-XTM 渦流式冷卻器分為兩型,第一種是50000H型,第二種是50000C型。
Nex FlowTMFrigid-XTM50000H型:適用於大多數工業的應用上,例如:電路板冷卻,加工零件冷卻,加工機具、刀具冷卻。提供溫度在0℃以上冷空氣,適合需要用大量冷空氣的場合。
Nex FlowTMFrigid-XTM50000C型:可提供小量極低溫冷凍空氣,最低可達-40°C。
