METHOD OF AND DEVICE FOR COOLING MAGNETOHYDRODYNAMIC GENERATOR CHANNEL Russian patent published in 1996 - IPC

FIELD: power engineering; MHD generators. SUBSTANCE: channel is cooled down by passing coolant through closed loop incorporating cooling zone and cooler. Part of main working medium flow is separated at channel outlet and used as coolant. Cooling zone is formed by clearances between channel walls and rear sides of electrodes. Coolant is admitted to cooling zone through nozzles mounted on inlet end wall of channel case. Nozzles are arranged along rear side of electrodes. Side walls of case in cooling zone mount additional nozzles arranged across cooling zone in spaces between jets of main nozzles. Electrodes are provided with holes to ensure communication between cooling region and working part of channel. EFFECT: improved cooling conditions. 6 cl, 2 dwg
