Abstract
A cooling arrangement for a motor assembly includes a motor operably connected to a load. Also included is a motor controller disposed adjacent to, and fluidly coupled to, the motor, the motor controller disposed within a housing enclosing a cooling fluid for immersion of a plurality of motor controller components. Further included is a duct arrangement configured to route a cooling flow to a location proximate the housing of the motor controller for cooling therealong.
Claims7
A cooling arrangement for a motor assembly comprising:
- a motor operably connected to a load;
- a motor controller disposed adjacent to, and fluidly coupled to, the motor, the motor controller disposed within a housing enclosing a cooling fluid for immersion of a plurality of motor controller components;
- a duct liner located radially outwardly of an outer surface of the housing and defining an annulus therebetween;
- a condenser disposed within the annulus and comprising a plurality of condenser fins extending from the outer surface of the housing;
- a duct arrangement configured to route a cooling flow to a cooling flow inlet disposed at an upstream end of the annulus for receiving the cooling flow for cooling of the motor controller;
- and
- a cooling flow outlet disposed at a downstream end of the annulus for routing the cooling flow along the motor, the cooling flow comprises vapor ingested into the duct arrangement.
