VENTILATION SYSTEM FOR CUBICLES WITH ELECTRONIC FUNCTIONAL UNITS PRODUCING CONSIDERABLE HEAT

摘要

The invention relates to a ventilation system for cubicles with functional units stacked, tower fashion, one above another and producing considerable heat, especially in data processing. Usually, an individual fan is provided for each functional unit and the hot air is discharged through the top of the cubicle concerned. Often, however, an air discharge at the front or back of the cubicle is desirable. The aim of the invention is therefore to provide such a ventilation system. To attain this aim according to the invention, four identical fan units (2) are arranged half-way up the cubicle (1) in such a way that there are two fan units (2) above each other and rotated through 180 DEG and two fan units (2) in identical positions side by side. The fan units consist of a fan housing (3) open on both longitudinal sides in which there is at least one axial-radial fan (4). Two of the fan units are fitted directly one on top of the other, while the other two are at a defined distance apart thus forming a horizontal air passage (5) between them. The fronts or backs of the fan units (2) are partitioned off by structural components in the cubicles.
