Abstract
To remove the heat generated in cabinets in which inserts carrying components in the form of electrical instruments are arranged one above the other, it is necessary to provide for cooling by use of convection or fans. This requires space between the inserts which takes up usable space in the cabinet. The novel insertable housing is intended to reduce the space required for ventilation and eliminate the need for the prior art fan inserts and metal guide sheets. In standard prior art systems, at least two height units were required for each ventilation measure. In the novel insertable housing, its jacket is only one height unit higher than the component carrier 1. An air intake shaft is provided within the jacket below the component carrier and above the component carrier is provided an air discharge shaft, with the air intake shaft being followed by a front air intake opening provided in a frontal frame and the air discharge shaft being followed by an air discharge opening in the rear wall of the housing. The insertable housing, which is suitable as a table-model housing as well as for insertion, is used within a 19-inch modular system.
