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.
Claims16
A housing for a dry-type electric machine, including a cooling system comprising:
- at least one plate-type heat exchanger for defining an inner circulation area and an outer circulation area of a cooling medium;
- first cooling channels provided within the housing, for conducting a flow of the cooling medium in a first direction around the electric machine;
- and
- second cooling channels for conducting a flow of the cooling medium in a second direction, opposite the first direction around the electric machine, the first cooling channels and the second cooling channels arranged in alternating order, wherein the housing accommodates the electric machine and the cooling system and forms a substantially hermetic encapsulation.
