Converter, comprising a converter housing with a first interior and a second interior, wherein - the first interior is arranged separately from the second interior, - part of the first interior protrudes into the second interior and forms a heat exchanger duct, - the converter can be operated such that a gaseous heat flow circuit is formed within the first interior which flows in through a first inlet opening of the heat exchanger duct and flows out through a first outlet opening of the heat exchanger duct, - the second interior forms a cooling duct, - the converter can be operated in such a manner that a gaseous cooling flow that flows through the cooling duct is formed, which flows around the heat exchanger duct, - the cooling duct is arranged in a region that overlaps with the heat exchanger duct, such that a first flow direction of the gaseous heat flow circuit runs substantially perpendicularly or parallel in relation to a second flow direction of the gaseous cooling flow, characterised in that - the converter is embodied to dissipate heat loss generated during operation in such a manner that - a first heat loss generated in the first interior is at least partially absorbed by the gaseous heat flow circuit, - the first heat loss absorbed in this manner is at least partially transferred from the gaseous heat flow circuit to the gaseous cooling flow of the second interior by means of the heat exchanger duct and is conducted away by means of the gaseous cooling flow and - a second heat loss generated in the second interior is at least partially absorbed by the gaseous cooling flow and is conducted away by means of the gaseous cooling flow. - the first interior is arranged separately from the second interior, - part of the first interior protrudes into the second interior and forms a heat exchanger duct, - the converter can be operated such that a gaseous heat flow circuit is formed within the first interior which flows in through a first inlet opening of the heat exchanger duct and flows out through a first outlet opening of the heat exchanger duct, - the second interior forms a cooling duct, - the converter can be operated in such a manner that a gaseous cooling flow that flows through the cooling duct is formed, which flows around the heat exchanger duct, - the cooling duct is arranged in a region that overlaps with the heat exchanger duct, such that a first flow direction of the gaseous heat flow circuit runs substantially perpendicularly or parallel in relation to a second flow direction of the gaseous cooling flow, characterised in that - the converter is embodied to dissipate heat loss generated during operation in such a manner that - a first heat loss generated in the first interior is at least partially absorbed by the gaseous heat flow circuit, - the first heat loss absorbed in this manner is at least partially transferred from the gaseous heat flow circuit to the gaseous cooling flow of the second interior by means of the heat exchanger duct and is conducted away by means of the gaseous cooling flow and - a second heat loss generated in the second interior is at least partially absorbed by the gaseous cooling flow and is conducted away by means of the gaseous cooling flow. - a first heat loss generated in the first interior is at least partially absorbed by the gaseous heat flow circuit, - the first heat loss absorbed in this manner is at least partially transferred from the gaseous heat flow circuit to the gaseous cooling flow of the second interior by means of the heat exchanger duct and is conducted away by means of the gaseous cooling flow and - a second heat loss generated in the second interior is at least partially absorbed by the gaseous cooling flow and is conducted away by means of the gaseous cooling flow.
