SYSTEM OF CLOSED ELECTRICAL MACHINE COOLING Russian patent published in 2015 - IPC H02K9/19 H02K5/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electric power engineering, particularly, to closed electrical machine cooling systems. Cooling system of electrical machine consisting of stator pack with working windings, rotor with permanent tangentially magnetised magnets comprises forced liquid cooling channels coved by bottom metal shell and made in cylindrical body that are provided with turbolisers. The latter can be shaped to prisms of rhombic cross-section. Inlet and outlet manifolds are arranged at machine body. Heat exchanger is composed of the chamber incorporated with said forced liquid cooling closed system arranged under bottom shell and closed from outer side. Blower is fitted on machine shaft while bypass holes are regularly spaced over its periphery in said body. Machine liquid cooling channels are separated by steel webs extending beyond said channels and into heat exchanger and have cut-outs separated by the webs and space regularly in circle.

EFFECT: higher intensity of cooling.
