Abstract:
1. An instrument cabinet comprising: a wall structure with vertical studs, a cooling element with a flow channel that comprises a group of substantially parallel channels for feeding cooling liquid in the vertical direction from bottom to top through the cooling element that is arranged upright and at least partly in the space between the vertical studs, at least one wall that separates the cooling element from a space containing electric components of the instrument cabinet, and between the wall and the wall structure of the instrument cabinet, there is a first part of the flow channel, in which air flowing through the flow channel is directed in the longitudinal direction of the cooling element from top to bottom, which is an opposite flow direction to the flow direction of the cooling liquid through the cooling element, and the space containing electric components forms a second part of the flow channel that is connected to the first part of the flow channel through openings at different heights, and a fan for cooling the electric components to be installed in the instrument cabinet with airflow produced by the fan, wherein the fan is located below the space containing the electric components, and draws air from the first part of the flow channel and to discharge air to the second part of the flow channel, and is aligned in such a manner that the airflow produced by the fan is directed directly upwards to the space containing the electric components.
