ABSTRACT:
There is described a modular electronic circuit wherein a series of electronics modules are penetrated by a passageway having an air-permeable wall, and cooling air is supplied to the passageway at a pressure above that obtaining in the modules, so that each module receives a supply of air passing out through the wall of the passageway. The passageway is constituted by a plurality of aligned tubular sleeves mounted in respective modules. There is also described a ventilation module including blowers to pressurize the passageway. A second passageway may be provided, at a reduced pressure, to extract air from the modules.
