Abstract:
A power control unit that controls a rotary electric machine that drives a vehicle, and that is mounted onto a motor case in which the rotary electric machine is housed, includes a fixed base (22) that is made of resin; a cooler (27) that is arranged on the fixed base (22) and that includes a power module; and a control substrate (29) that is arranged on the cooler (27). The fixed base (22) inhibits conduction of heat from the motor case (31) to the power control unit.
Abstract:
An electric pump comprises an outer housing including a motor cavity and a controller cavity separated by a partition wall. An inner housing is positioned within the motor cavity of the outer housing. One of the inner and outer housings includes radially extending ribs positioned adjacent to the other of the inner and outer housings to define a coolant flow path between the inner housing and the outer housing. The flow path is partially defined by the partition wall. An electric motor is positioned within the inner housing and includes a hollow rotor shaft driving a pump member. The hollow rotor shaft forms a portion of the coolant path and interconnects a volume between the inner and outer housings with a low pressure cavity containing the pump member. A controller is positioned within the controller cavity in heat transfer relation with the partition wall.
Abstract:
The invention is directed at articles and devices for thermal energy storage, and for process of storing energy using these articles and devices. The articles comprise a capsular structure 10 having one or more sealed spaces 14, wherein the sealed spaces encapsulate one or more thermal energy storage materials 26: wherein the capsular structure has one or more fluid passages 16 which are sufficiently large to allow a heat transfer fluid to flow through the one or more fluid passages; and when a heat transfer fluid contacts the capsular structure 10 the thermal energy storage material 26 is Isolated from the heal transfer fluid. The devices include two or more articies arranged so that a fluid, such as a heat transfer fluid, may flow through the fluid passage 16 of an article before or after flowing through a space between two of the articles.
Abstract:
Cooling systems and methods of use are disclosed. A particular method includes routing at least a first portion of a coolant stream from a first heat exchanger to a second heat exchanger to receive heat from a hot side of a thermoelectric cooling device. The method also includes cooling one or more electronic devices using a cold side of the thermoelectric cooling device. The method also includes routing at least a second portion of the coolant stream to an engine.
