Bird 20kW负载8745 8746
20 kW, Water-Cooled Terminations are designed as compact, low VSWR and non-radiating terminations for high-power transmitter/transmission line systems. The units generate almost no ambient heat, making installation space minimal and convenient, in any position. The RF power is converted to heat in the hollow resistive film load resistor and directly absorbed by the water flowing through it. Broadband water-cooled load for long-term RF dissipation when heat must be efficiently transferred away from the area Small size may be carried easily, used in any position and installed anywhere there is a source of potable water Requires flow rate of up to 8 gallons (30.4 liters) per minute 20千瓦水冷终端结构紧凑,低电压驻波比和非散热器大功率发射机/传输线系统。单位产生几乎没有周围的热量,使安装空间*小,可放在任何位置。射频功率转换为中空式电阻负载电阻热由水流过它直接吸收。 宽带水冷负荷长期射频热耗散时,必须有效地转移远离该区域 体积小,可随身携带,使用和安装在任何位置都有一个饮用水源 需要多达8加仑(30.4升)的流量每分钟
