Abstract
The electric module includes a sealed enclosure (104), at least one item of electrical equipment (106) arranged in the sealed enclosure (104) and which, in operation, heats the atmosphere, and a secondary cooling circuit. The secondary circuit includes a guiding channel (108) arranged in the sealed enclosure (104) so as to guide the atmosphere which has been heated by the item or items of electrical equipment (106) towards its top opening (108B), and a passage (109) for the atmosphere delimited, at least partly, by the sealed enclosure (104) in order to enable a cooling of the atmosphere upon contact with the sealed enclosure (104). The guiding channel (108) is thermally isolated from the sealed enclosure (104).
