An integrated circuit device is provided. The integrated circuit device includes a die having a first surface and a second surface opposite the first surface. The die has at least one circuit element positioned on its first surface. At least one micro-channel is defined in the second surface of the die. The integrated circuit device includes a cooling substrate attached to the second surface of the die. At least one fluid routing channel is defined in the cooling substrate. The at least one fluid routing channel is connected to the at least one micro-channel defined in the die. Additionally, the cooling substrate has at least one valve positioned within the at least one fluid routing channel. The at least one valve is configured to autonomously regulate a flow rate of a cooling fluid flowing through the at least one fluid routing channel.

An electrical device is described herein. The electrical device includes a housing that includes an inner surface that defines a cavity, a heat sink that is coupled to the housing and oriented along a first plane, and at least one electrical component positioned within the housing cavity and oriented along a second plane that is different than the first plane. A heat exchange assembly is coupled to the electrical component and the heat sink for adjusting a temperature of the electrical component. The heat exchange assembly includes an evaporator section, a condenser section, and a transport section extending between the evaporator section and the condenser section for channeling a working fluid between the evaporator section and the condenser section. The heat exchange assembly is configured to bend along at least one bending axis oriented with respect to the transport section.

A synthetic jet assembly includes a synthetic jet having a cavity and an opening formed therein. The synthetic jet assembly also includes an actuator element coupled to a second surface of the body to selectively cause displacement of the second surface, and a control unit electrically coupled to the actuator element. The control unit is configured to transmit a multi-frequency drive signal to the actuator element, the multi-frequency drive signal comprising a cooling frequency component and an acoustic frequency component superimposed on the cooling frequency component. The cooling frequency component causes a cooling jet to eject from the opening of the body. The acoustic frequency component produces a desired audible output.

An electrical machine includes a stator having a radically inwardly directed duct adjacent the center of the machine for flowing cooling medium into the gap between the stator and rotor. The rotor includes radial or diagonal ducts having scoops for directing flow generally radically inwardly to cool the field windings in the center of the machine. The cooling medium flows either into subslots for radial or diagonal outward flow through outlet ducts for return to the gap.
