<p>The present invention relates to a method and an apparatus for cooling heat generating units, such as mobile telephone equipment in a radio base station. By providing a heat excahnger (69) having crossing flow directions for an internal vertical air flow (76) and external lateral, cooling air flows (70, 73) in a vertical area, such as a wall portion to the radio base station, for instance as a part of a door to the radio base station, excellent cooling may be achieved without substantially affecting the space by means of the heat exchanging function, which is intented for the equipment.</p> |
