Abstract: The invention relates to an air-conditioning box comprising a heat exchanger for regulating the temperature. The air-conditioning box is used especially in systems for cooling computer centers or servers. The special design of the heat exchanger allows energy costs to be reduced such that systems operating with the air-conditioning box of the invention use less energy.

Abstract: This invention entails an air conditioning device (2) for cooling an electronic device cabinet or the like. It is equipped with a housing, an air supplying device (10) and a heat exchanger (4). The air supplying device (10) sucks air in from one side and conducts it through a heat exchanger (4) to a second side (14) and supplies it in radial direction to the second side (14). The heat exchanger (4) is connected so as to impact with its external or internal cooling device the heat exchangers with cooled cooling medium. The outgoing current of radially streaming air is applied to front surface of adjacent electronic device cabinets so that the air can thus be used without being substantially mixed in advance with warmer air. The air can also be sucked in by the electronic device cabinets and used for cooling without losses of efficiency levels.
