The industrial climate has become increasingly important in recent years. Was formerly the heat of the components active cooling today be discharged or passively increasingly in demand. Passive cooling was realized as recordable only by the heat dissipation through the cabinet surface through ventilation grille or thermal coupling of particularly heat-problematic components. The disadvantages are but with the different methods are obvious: the surface cooling is too dependent on the site and on the ambient temperature. Open air vent control cabinet while for fresh air, but also for unwanted foreign matter / deposits, which in turn can lead to a failure of the system. The thermal coupling ultimately leads to conscious formation of hot spots. All three cooling concepts have one big disadvantage together: they are not or poorly controllable.
With active cooling, the heat dissipation is controlled. As a basis for adequate cooling solution one must first determine the basic data: How much cooling capacity I need anything, the cooling performance is continuously demanded what conditions prevail at the location of the cabinet, there are limitations in terms of space, volume, tension? After these considerations, one should select the appropriate cooling components.
