Abstract: A cooling plant for cooling one or more switch cabinets. According to this invention, a large heat exchanger or several small heat exchangers operating in parallel are housed in a heat exchanger cabinet, wherein an inner space of the heat exchanger cabinet is coupled to a central air-conditioning device supplying cold air to a double bottom by an air inlet in the cabinet bottom and an air outlet of the double bottom. The cold air fed to the heat exchanger cabinet goes through the large heat exchanger or the small heat exchangers and cools the coolant flowing therein. The water supply and the water return of the large heat exchanger or the small heat exchangers are connected to the feed line and the return line of the switch cabinets that are to be cooled. This simple construction makes it possible to easily adapt the efficiency of cooling and the capacity to the variable number of switch cabinets.

Abstract: A unit arrangement having a receiving housing, in particular a switchgear cabinet, in an interior of which electrical units are accommodated and having a cooling device which is in air-conducting communication with the interior of the receiving housing via at least one air inlet and at least one blower aperture, and a cooling operation monitoring device. A requirement-orientated control of the cooling operation is possible when the cooling operation monitoring device has an inlet temperature sensor which measures a temperature of the air to be cooled which is supplied to the cooling unit via the air inlet. An outlet temperature sensor measures a temperature of the cooled air which is supplied to the interior of the receiving housing via the blower aperture. A computing unit of the cooling operation monitoring device determines a temperature difference between the temperature measured by the inlet temperature sensor and the outlet temperature sensor.

Abstract: A liquid cooling system having cooling units individually assigned to electronic component groups housed in a rack or a switchgear cabinet, which are to be cooled, and having a monitoring and control arrangement for monitoring a cooling temperature. Effective cooling and temperature monitoring is obtained because the cooling units are liquid cooling units and are connected via branch points to a common central liquid line system integrated into the rack or the switchgear cabinet. The control and monitoring arrangement is for monitoring the cooling temperature in the central liquid line system and for emitting an error signal when a predetermined or a predeterminable threshold temperature in a liquid return branch is exceeded, or when a predetermined or predeterminable threshold temperature difference between a temperature in an inlet branch and a temperature in the return branch is exceeded, or when the liquid flow falls below a predetermined or predeterminable threshold value.

Abstract: A housing arrangement including a receiving housing with an interior inside which a cooling device and one or several electric units are accommodated. The cooling device includes a flow line and a return line extending at least partially between the base area and ceiling area of the receiving housing. Connecting lines run from the flow line and the return line and are physically connected to a cooling circuit of one or several electric units. Effective cooling of receiving areas which are fitted in a complex manner with built-in components is obtained because a distributor line is respectively guided from a flow line and a return line to a distributor which is maintained inside the receiving housing. The distributor includes several distributor connections that can be connected to connection lines which are guided to the electric built-in component, such as a computer unit.

Abstract: An assembly of devices including at least one switchgear cabinet and a cooling device. The switchgear cabinet has a closed interior, in which electric installations can be housed. The cooling device is attached in the vicinity of or near a lateral surface of the switchgear cabinet that runs vertically with respect to the front face, extending at least over part of the height of the switchgear cabinet and having a spatial connection with the interior via at least one air inlet and at least one vent outlet. The cooling device includes a receiving chamber that houses at least one heat exchanger. This invention facilitates the adaptation of the cooling device in superstructures of this type to modified cooling requirements. To achieve this, at least sections of the receiving chamber of the cooling device are divided into two or more receiving sub-chambers that are situated one above the other and a cooling module is housed in at least one of the receiving sub-chambers.

Abstract: A cooling system for cooling a switchgear cabinet including, in the interior thereof, heat generating built-in components situated one above the other and to which individual heat sinks are assigned and included in a coolant circuit via a flow line and a return line. The heat sinks are connected to the flow line and to the return line via individual unit supply lines and are supplied with coolant. The coolant circuit is closed via the coolant exit side of the air/water heat exchanger. The air/water heat exchanger is arranged in the bottom area of the switchgear cabinet, and is coupled, via air entry side by an air entry opening of the switchgear cabinet bottom and of an air outlet opening of a double bottom of a setting-up bottom of the switchgear cabinet, to a central air-conditioning device, which supplies the double bottom with cool air. A pump and an expansion tank are included in the closed coolant circuit.
