Cooling
N003E cooling system
The high-power transmitters (klystron tubes) are cooled by “closed cycle” liquid system.
The working temperature of the liquid “antifriz 65” is +55°C.
The cooling system is engaged immediately after the radar is switched on.
The front radar bay is cooled with “ram” air. The flow volume is 650-800kg/h.
The air-cooling system maintains operating temperature of 55-60°C inside the radar bay.
If the temperature exceeds limit, the cooling slots are closed.
