Patent ID: 8418679

Claim:
A charger module for an internal combustion engine, comprising: a mechanical charger, two charge air coolers, wherein the two charge air coolers are positioned downstream from the mechanical charger for cooling compressed charge air; and wherein the mechanical charger is arranged along a centerline of the charger module between the two charge air coolers; an air distributor, wherein the air distributor is arranged between the mechanical charger and the charge air coolers; a bypass for partial-load adjustment, wherein the bypass is arranged above the mechanical charger; a one-piece, sand-cast, aluminum housing, wherein the one-piece, sand-cast, aluminum housing surrounds the mechanical charger, the two charge air coolers, the air distributor, and the bypass on at least a bottom side of the charger module and on two opposite sides of the charge module; and wherein the one-piece, sand-cast, aluminum housing further comprises: a first face having an opening for inserting the mechanical charger and the two charge air coolers, a second face, opposite to the first face, having an air intake opening, a bottom face comprising a plurality of air outlet openings, wherein the plurality of said air outlet openings, are arranged below the two charge air coolers, a vertical air channel for circulating air from the air intake to the mechanical charger through the air distributor and to the plurality of said air outlet openings, a plurality of parallel cooling fins arranged in a longitudinal direction of the two charge air coolers, parallel to a compressor shaft of the mechanical charger, and between opposite front boundary walls of the vertical air channel, and a plurality of connections for supply and removal of cooling water to the plurality of said parallel cooling fins, wherein air flowing through the vertical air channel flows in a cross-current direction with respect to cooling water flowing through the plurality of said parallel cooling fins.
