FIELD: mechanical engineering.
SUBSTANCE: construction includes inlet air duct passing in parallel to flat base of body and being spaced form it for given distance. Excluding side inlet apertures for air, air duct is compacted relatively to the body and inlet side of compartments or sections, placed inside the body. On remote relatively to inlet apertures end of inlet air duct a recess is made for mounting a cooler. This cooler forces air vertically into compartment below inlet air duct, and this lower compartment is connected to side branch by air duct. Hot processed air is forced through outlet duct and is let out from the body in side direction. Along direction of air flow below cooler at least one electronic block and heat source is mounted, cooled by this flow. Second recess in inlet air duct is placed higher in direction of flow from recess with cooler mounted in it. In said second recess a cooled component is placed, which projects into lower compartment.
EFFECT: optimized cooling of inner components with minimized noise radiation.
