Abstract: A cooling system, in particular for electronics cabinets, is proposed, comprising a casing, wherein the casing comprises at least a cabinet side partitionment, wherein the cooling system comprises a first cooling circuit and a second cooling circuit, wherein the second cooling circuit is an active cooling circuit, wherein the first cooling circuit and the second cooling circuit are thermally coupled, wherein the second cooling circuit is not disposed in the cabinet side partitionment.

Abstract: A heat exchanger including a first heat absorbing section and a second heat releasing section, such that a plurality of heat exchange structures are arranged, preferably in parallel, in a plane of extension. The first heat absorbing section includes a first plurality of fluid guiding devices and the second heat releasing section comprises a second plurality of fluid guiding devices. Each heat exchange structure includes at least one fluid guiding devices of the first plurality and at least one fluid guiding devices of the second plurality thermally connected to each other, and preferably arranged in parallel. A clearance disposed between two adjacent heat exchange structures allows airflow between adjacent heat exchange structures and/or each heat exchange structure includes a heat sink to thermally couple the fluid guiding devices of the first plurality and the fluid guiding devices of the second plurality.

Abstract: A cooling system, in particular for electronics cabinets, comprising a casing, wherein the cooling system comprises a first cooling circuit and a second cooling circuit, the first cooling circuit comprising a heat releasing section and the second cooling circuit comprising a heat releasing section, is provided, wherein the casing comprises at least three compartments including a cabinet side compartment, a first external side compartment and a second external side compartment, wherein the three compartments are fluidically separated from each other so that respective airflows in the cabinet side compartment, the first external side compartment and the second external side compartment do not mix, wherein the heat releasing section of the first cooling circuit is arranged in the first external side compartment and wherein the heat releasing section of the second cooling circuit is arranged in the second external side compartment.

Abstract: In order to arrange an air passage device for the admission and purification of air, in particular ambient air, into the interior of a control cabinet or computer housing in such a way that the device can be used also in an environment which is subject to an increased degree of pollution, a first purifying includes a centrifugal separator.
