Abstract

The disclosure relates to a housing for an electric machine, for example, an electric power transformer, such as a dry-type transformer, with cooling channels being provided within the housing for a cooling medium. The electric machine and a cooling system can be arranged in the housing, with vertically arranged first and second channels for the cooling medium being provided. The medium can flow around the electric machine, with the housing accommodating the electric machine and the cooling system substantially forming a hermetic encapsulation.
