Covered-cassette-cooling element performance raising device, has small-radial ventilator absorbing convection air, and rotary-air passage blowing-out convection air, where passage distributes convection air over covered-cooling elements

摘要

The device has a small-radial ventilator (2) absorbing a convection air (1), and a rotary-air passage (3) blowing-out the convection air. The rotary-air passage distributes the convection air over covered-cooling elements (4) to perforated longitudinal sides (5). A warm air is upwardly raised over an expansion gap (6) of the cooling elements, and an air passing element consists of a connection plate (8) for a ventilator (9), an air passage plate (10) and an adjustable blowing-out segment (11).
