Embodiment Construction

[0019] figure 1 Shown is a horizontal cross section cut through a row of switch cabinets 20 in which a cooling device 1 designed according to the prior art is integrated. As can be seen from the figure, the cooling device 1 protrudes beyond the front side of the switch cabinet 20 on the side of the cold air opening, through which the switch cabinet 20 draws in the cooling air already provided by the cooling device 1 . Due to the protruding front of the cooling device 1 into the cooling vent, the cooling device 1 according to the prior art forms an obstacle that locally compresses the cooling vent and thus also adversely affects the air distribution within the cooling vent. The switchgear 20 blows the heated air through its rear side into the hot air inlet, while the heated air is sucked in through the air inlet 2 of the cooling device 1 , conducted through the heat exchanger 4 , and with the aid of a centrifugal ventilation The ventilation unit 5 of the machine is blown out l...

Abstract

The invention relates to a cooling apparatus (1) for control cabinet cooling, the cooling apparatus having an air inlet side (2) for hot air and an air outlet side (3) for cooled air, wherein a heat exchanger (4) and at least one fan unit (5) having a radial fan (6) are arranged between the air inlet side (2) and the air outlet side (3). Between the air inlet side (2) and the air outlet side (3) the fan unit (5) generates an air current having a main flow direction (x) through the heat exchanger (4), the fan unit (5) being arranged in the main flow direction (x) downstream of the heat exchanger (4). The invention is characterised in that the fan unit (5) has an air ducting geometry (7) such that air exiting from the radial fan (6) is diverted into the main flow direction (x).

Description

technical field [0001] The invention relates to a cooling device for cooling switch cabinets, the cooling device having an air inlet side for hot air and an outlet side for cold air, wherein on the air inlet side and the outlet side Arranged between the heat exchanger and at least one ventilation unit with a centrifugal fan, and wherein the ventilation unit between the inlet side and the outlet side generates an airflow with a main flow direction through the heat exchanger, wherein , place the ventilation unit after the heat exchanger in the main flow direction. Such a cooling device is known from the published international application PCT / EP2011 / 052932. Background technique [0002] This type of cooling device is especially used in computing centers with cold air outlets and hot air outlets, wherein the cold air outlets and hot air outlets are separated by a row of switch cabinets erected in sequence on a straight line. In this case, cooling devices of this type are desi...
