A control cabinet arrangement, comprising a cooling device which is received in a control cabinet housing, wherein the cooling device can be slidably held on the control cabinet housing via a linear adjusting unit, particularly a bar system, and can be adjusted between a pull-out position and a slide-in position, wherein the cooling device in the slide-in position is completely received in the control cabinet housing, and in the pull-out position, the cooling device protrudes at least partially beyond a door side of the control cabinet housing from the control cabinet housing, and wherein a door element, which closes in its closed position the door side of the control cabinet housing, comprises at least one air passage opening which opens into an air outlet and/or an air inlet of the cooling device in the closed position of the door element, when the cooling device is in the slide-in position.

Electrical enclosure assembly comprising a cooling device which is received in an electrical enclosure housing

The invention relates to a heat exchanger for cooling a switch cabinet, with a first line system for a first coolant and with a second line system, separated fluidically from the first line system, for a second coolant, in which the first and the second line system are coupled thermally to one another, and to a corresponding switch cabinet.

Heat exchanger for cooling a switch cabinet and corresponding cooling arrangement

A cooling unit for cooling the air admitted to the interior of a switchgear cabinet (), which cooling unit has an inner circuit, through which the air to be cooled is routed from a switchgear cabinet interior, and an outer circuit () which is fluidically partitioned from the inner circuit and through which the surrounding air is routed, wherein the inner circuit contains a first heat exchanger and the outer circuit contains a second heat exchanger, between which a coolant is circulating, wherein the heat exchangers have an air flow direction along which the heat exchangers allow air to pass between an air inlet side and an air outlet side, characterized in that at least one of the heat exchangers has a first air guide upstream on the air inlet side, which extends at an angle with 5&#x3c;&#x3b2;&#x3c;45&#xb0; relative to the air inlet side and forms an air duct between itself and the air inlet side, which tapers along a dimension of the air inlet side.

Cooling unit for cooling the air admitted to the interior of a switchgear cabinet, and a corresponding switchgear cabinet arrangement

The disclosure relates to a cooling device, in particular for cooling components that are housed in a switchgear cabinet, comprising a first cooling fan for blowing air from the switchgear cabinet through a first heat exchanger, and a second cooling fan for blowing ambient air through a second heat exchanger, characterized in that the cooling device further comprises a voltage supply having a step-up and/or step-down converter, which is connected via a rectifier to a wide-range input for single-phase or multiphase AC voltage, and which charges a capacitor to a DC link voltage which is higher or lower than a mains voltage across the wide-range input, a power supply unit of at least one of the two cooling fans being connected in parallel to the capacitor. The disclosure further relates to the use of such a cooling device and to a corresponding method for operating the cooling device.

Cooling device, in particular for cooling components housed in a switchgear cabinet, corresponding use and corresponding method

The invention relates to a switch cabinet with a cooling apparatus which has a first closed coolant circuit and a second closed coolant circuit separated fluidically from the first coolant circuit, the first coolant circuit having a refrigerating machine or a cold water set and the second coolant circuit having a heat pipe arrangement.
