FIELD: heat engineering.
SUBSTANCE: invention relates to the field of heat engineering and can be used in air cooling apparatuses (ACA). In an air cooling apparatus consisting of a heat exchanger unit, a fan with a drive, and supports, wherein frames with a mesh and a filtering sheet are installed between said supports, axes are fixed on the inner side of the mesh, whereon valve curtains made of an air-impermeable material are installed, wherein the axes are fixed vertically on the inner side mesh.
EFFECT: stabilisation of the pressure and flow of the cooling air jet along the entire perimeter of the working structure, reduced losses for throttling of air (gas) in the system, as well as increased heat exchange efficiency.
