  • Instrument cabinet
    Publication number: 20070030651
    Abstract: The invention relates to an instrument cabinet comprising: a wall structure with vertical studs, a fan for cooling electric components to be installed in the instrument cabinet with an airflow produced by the fan, and a cooling element arranged in the airflow and having a flow channel for feeding cooling fluid through the cooling element for cooling the airflow that cools the electric components. To achieve a lower than before instrument cabinet that has fewer risks of leakage, the cooling element is arranged upright and at least partly in the space between the vertical studs.
