FIELD: power industry.
SUBSTANCE: device includes chamber for the object to be cooled, fan the delivery part of which is connected to supply system of cooling air to cooled object chamber. System of air supply to the cooled object chamber includes air pipelines which are located on both sides of cooled object; at that, inlets of air pipelines are connected to delivery part of the fan. Besides, this system is provided with guide elements for cooling air, which are located on both sides of cooled object between air pipelines and cooled object, releasing elements located on the outlet side of each air pipeline and forming together with guide elements and cooled object the recirculation channels of cooling air, the inlets of which are connected to outlets of air pipelines, and outlets are connected to suction part of fan. At that, cooled heat exchangers are installed in air pipelines.
EFFECT: increasing efficiency of air cooling device.
