Embodiment Construction

[0026] An important field of application of the invention is large engines, such as large two-stroke diesel engines, preferably provided with an exhaust gas turbocharger. Engines of this type are used extensively in marine propulsion. exist figure 1 An engine of this type is shown in . Although the invention will be described by means of this preferred embodiment, it should not be construed as limiting the invention thereto.

[0027] asfigure 1 Engines of the basic type generally comprise a plurality of cylinders 1 arranged side by side in rows, said cylinders having an upper exhaust gas outlet 3 controllable by an exhaust valve 2 and a lower one controlled by pistons 4 which move up and down. The air inlet slit 5 is used to supply the necessary air to the working chamber through the air inlet slit. The exhaust gas outlets 3 of the cylinders 1 lead into an exhaust gas manifold 6 . The air inlet slit communicates with a distribution pipe 7 . In naturally aspirated engines,...

Abstract

The invention relates to an air loaded air cooler (9) such as an engine. The air cooler has an area (15) designed to a heat exchanger arranged between an air inlet and an air outlet. The area contains a plurality of vertical flow passages (18) which is crossed by an uncooling air from up to down and limited by an outer cooling surface, wherein a high reliability and a long service life can be realized by that the area (15) designed to the heat exchanger is rotated about a half rotation around an axis which traverses the uncooling air and extends along the flow direction from up to down, and the area (15) designed to the heat exchanger can be loaded by the uncooling air crossing the area from up to down at an up and down reversal position which is rotated about a half rotation.

Description

technical field [0001] The invention relates to a method for cleaning an air cooler and a device for carrying out the method, as well as an air cooler designed for this purpose. Background technique [0002] Contaminants (impurities) in the form of dust particles or the like brought into the air cooler by the air to be cooled can narrow and block the flow channels assigned to the air. According to experience, such narrowings or blockages are already formed at a small distance from the inlet side, i.e. from the upper side of the air cooler, where condensation water usually also starts to form, so that the pollutants are humidified and can interact with each other. Gather into a viscous substance. As the flow channel narrows or becomes progressively more clogged, a progressively higher pressure drop occurs. Once the pressure drop has reached the specified level, the air cooler must be cleaned. The problems described above occur, for example, in engines operating with intern...
