CABINET FOR HOLDING RADIO-ELECTRONIC EQUIPMENT Russian patent published in 2005 - IPC

FIELD: engineering of devices for positioning and cooling heat-producing radio-electronic equipment.

SUBSTANCE: in accordance to invention, forced air cooling by cooling machine is implemented. Radio-electronic equipment is positioned in no less than two vertical stands of cabinet. Equipment with varying heat production is positioned in levels in different posts, separated from each other by wall with apertures made between levels. Cooling of equipment with low heat production is performed by influx ventilation in upward direction with preliminary passage of air from atmosphere through evaporator of cooling machine for its cooling and drying. Cooling of equipment with significant heat production is performed by air-ejection ventilation in downward direction with addition of cold air, injected through apertures in wall from adjacent stand. Processed air, after passing through accumulator of cooling machine and cooling it in the process, is finally forced into atmosphere by ejection ventilator.

EFFECT: increased efficiency of radio-electronic equipment cooling, decreased energy costs of cooling.
