Abstract
A gas-cooled heat exchanger, in particular a direct intercooler, for cooling of a fluid which flows through the heat exchanger, with a heat transfer block featuring a plurality of flow channels, with a first collection chamber and a second collection chamber. The collection chambers are fluidically connected with one another via the flow channels and the outside of the heat transfer block can be perfused by gas. In the direction of the perfusion, a screen is arranged in front of the heat transfer block for the prevention of flow in certain areas around the flow channels of the screen. One of the collection chambers features a vent for discharge of condensate of the fluid which can be sealed from or released into the surrounding area of the heat exchanger.
