Abstract: A cooling assembly includes a device chamber containing a device chamber cooling medium, a heat exchanger including at least one cooling surface in contact with the device chamber cooling medium, a control unit configured to control the heat exchanger, a humidity sensor configured to detect a humidity level in the device chamber, and a receptacle. The control unit is configured to perform a dehumidification operation as a response to the humidity level exceeding a predetermined threshold value in the device chamber. The dehumidification operation includes lowering a temperature of the at least one cooling surface in order to condensate water from the device chamber cooling medium on the at least one cooling surface. The receptacle is configured to receive water dripping from the at least one cooling surface.

Abstract: A cooling assembly includes a device chamber, a cooling chamber separated from the device chamber, a heat exchanger, a device chamber fan arrangement and a control unit. The heat exchanger includes a first portion located in the device chamber and a second portion located in the cooling chamber for transferring heat from the device chamber to the cooling chamber. The device chamber fan arrangement is configured to generate a device chamber cooling medium flow including a first partial flow interacting with the first portion of the heat exchanger. The cooling assembly also includes a first throttle arrangement for regulating the first partial flow. The control unit is configured to reduce a cooling power of the heat exchanger as a response to predetermined operating conditions by decreasing the first partial flow with the first throttle arrangement.

Abstract: Exemplary embodiments are directed to an equipment space that is a closed space provided with electrical equipment and an air dryer condensing the moisture of the air in the equipment space into water. A system for removing water from the equipment space includes a porous element having a capillary structure and being located in an outlet opening of the equipment space. The porous element is connected such that water condensed by the air dryer is directed to a first inner surface of the porous element. The capillary structure of the porous element is configured to propogate water from the inner surface of the porous element to an outer surface of the porous element. The outer surface of the porous element is configured to release water to ambient air outside the equipment space.
