1. A device for cooling a gas flow of an internal combustion engine, comprising a metal housing comprising a first wall section and a second wall section;the housing further comprising first surface facing a first direction and a second surface facing a second direction, the second direction being opposite to the first direction,said first surface having a gas flow channel surrounded by the first wall section,said second surface having a cavity between the first wall section and the second wall section, a liquid coolant flowing through the cavity on said second surface,said housing further comprising at least one cover part that is not integrally formed with the first and second wall section;a duct conveying the coolant arranged in the cover part;wherein the cover part comprises two plate-like elements that are arranged on top of another, and the duct is formed by a recess in at least one of the plate-like elements;an inlet and an outlet for the gas flow to be cooled, wherein the gas flow comprises at least one of exhaust gas and charge air of the internal combustion engine;an inlet and an outlet for the liquid coolant;a heat exchanger for heat transfer between the gas flow and the coolant;a side cover disposed adjacent to the first wall section, wherein the side cover includes a plurality of deflection bars disposed such that the liquid coolant is deflected at multiple locations;wherein the first wall section is arranged between the coolant and the gas flow and wherein a first side of the first wall section is in direct contact with the coolant and a second side of the first wall section is in direct contact with the gas flow, the first and second sides of the first wall section being parallel to each other and are facing opposite directions,andthe second wall section is arranged between the coolant and the atmosphere surrounding the metal housing and wherein a first side of the second wall section is in direct contact with the coolant and a second side of the second wall section is in direct contact with the atmosphere surrounding the metal housing, the first and second sides of the second wall section being parallel to each other and are facing opposite directions; andwherein the first wall section and the second wall section are materially integrally formed in one piece. 2. The device according to claim 1, wherein the housing comprises the first and the second wall section comprises a die-cast part. 3. The device according to claim 1, wherein the cover part comprises a seal for sealing off at least one of the coolant and the gas. 4. The device according to claim 1, wherein the cover part is soldered to the housing. 5. The device according to claim 1, wherein at least the inlet or the outlet for the coolant is arranged on the cover part. 6. The device according to claim 1, wherein at least part has an overflow opening connecting the duct to the housing. 7. The device according to claim 1, wherein the heat exchanger is formed as a stack of disks, and the stack is capable of allowing the coolant to flow through the heat exchanger and the gas to flow around the heat exchanger. 8. The device according to claim 1, wherein the heat exchanger comprises a tube bundle. 9. The device according to claim 1, wherein a valve member for the adjustable regulation of a total amount of gas flow is arranged in the housing. 10. The device according to claim 9, wherein a deflection of the gas flow through the heat exchanger or a bypass path is adjustable via the valve member. 11. The device according to claim 1, wherein the first wall section is entirely located inside the housing.
