ELECTRICAL MACHINE Russian patent published in 2016 - IPC H02K9/18 H02K1/20 H02K1/32 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to devices for cooling of electric machines with detachable cooler. On upper side of housing (1) of electrical machine near front/back ends (5, 6) there are holes (7, 8) for air inlet, and between them there is hole (9) for air outlet; front/rear elements (10, 11) for air injection, by means of which air is inhausted through holes (7, 8) for air inlet and is exhausted through hole (9) for air outlet. Detachable cooler (13) includes front/rear removable separation walls (16, 17), which are arranged between outlet hole (9) and corresponding hole (7, 8) for air inlet, and extend from upper side of housing (1) upwards. In housing (1) with detachable cooler (13) there are guide elements (22, 23, 28, 29) and transverse separation walls (24, 27), through which air, exhausted from the hole (9) for air outlet in area facing to corresponding hole (7, 8) for inlet of air is supplied to respective other hole (8, 7) for air inlet.

EFFECT: technical result consists in reduced to minimum temperature difference between air supplied via front air inlet hole and rear air discharge hole.
