Abstract:
A device (201) is provided which includes a host device (203) having a heat source (205) therein. A synthetic jet ejector (207) is embedded in the host device and is equipped with a temperature sensor (205) and a controller (211) which controls the operation of the synthetic jet ejector. The controller starts the synthetic jet ejector only when the temperature sensed by the temperature sensor exceeds a minimum threshold value Tv.
Abstract:
A method is provided for operating a thermal management system which includes providing a set of synthetic jet actuators A={a1, . . . , an} (309, 311, 313), wherein n≧3, and wherein each member of A has a diaphragm which oscillates along a principle axis. The members of set A are arranged and operated such that they have corresponding forces F1, . . . , Fn at any given time during their operation, wherein any force Fk ε {F1, . . . , Fn} has vector components along mutually orthogonal axes x, y and z of Fkx, Fky, and Fkz, wherein at least one of the sets Sx={|F1x|, . . . , |Fnx|}, Sy={|F1y|, . . . , |Fny|} and Sz={|F1z|, . . . , |Fnz|} has more than one member, and wherein the sum TF=Σi=1n Fi is essentially zero.
