Converter having a separate interior

A converter, converter, comprising:

• a converter housing having a first interior and a second interior, said first interior arranged separately from said second interior and having a part which protrudes into the second interior to form a heat exchanger duct, said second interior configured to form a cooling duct;
• a gaseous heat flow circuit formed within the first interior, said gaseous heat flow circuit flowing in through an inlet opening of the heat exchanger duct and flowing out through an outlet opening of the heat exchanger duct;
• and
• a gaseous cooling flow flowing through the cooling duct and flowing around the heat exchanger duct,
• wherein the cooling duct formed by the second interior 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,
• wherein the converter is configured to dissipate heat loss generated during operation such that a first heat loss generated in the first interior is at least partially absorbed by the gaseous heat flow circuit and at least partially transferred from the gaseous heat flow circuit to the gaseous cooling flow via the heat exchanger duct and conducted away by 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 conducted away by the gaseous cooling flow.
