摘要:
A method is provided for forming tinsel on a synthetic jet actuator. The method comprises (a) providing a synthetic jet actuator assembly (201) comprising a bobbin (203), a voice coil (213), driver electronics (215), and a surround (205); and (b) printing polymer thick film (PTF) conductive ink (209) across the surround, thus connecting the voice coil to the driver electronics.
摘要:
A system is provided for producing synthetic jets. The system comprises a first synthetic jet ejector equipped with a first diaphragm which operates at a first frequency f1, and a second synthetic jet ejector equipped with a second diaphragm which operates at a second frequency f2. The first and second synthetic jet ejectors are positioned with respect to each other such that the sound intensity of at least one of the first and second synthetic jet ejectors is reduced through destructive interference, wherein f1 and f2 are out-of-phase by φ degrees, and wherein 20≦φ≦60.
摘要:
A device, comprising (a) a chamber having a liquid disposed therein, (b) an LED array having a first surface which is in contact with said liquid, and (c) at last one actuator adapted to dislodge vapor bubbles from said first surface through the emission of pressure vibrations.
摘要:
A light source (101) is provided which comprises (a) a housing element (107); (b) a heat sink (109); (c) a first flow channel element (111) which, alone or in combination with said housing element, creates (i) a first set of flow paths (221) for the flow of fluid in a first direction through the light source, and (ii) a second set of flow paths (223) for the flow of fluid in a second direction through the light source; (d) a set of synthetic jet actuators (143, 145) having at least one member and being in fluidic communication with said first set of flow paths; and (e) a set of LEDs (113) containing at least one member and being in thermal contact with said heat sink.
摘要:
A synthetic jet ejector is provided which comprises (a) an LED (119), (b) a heat sink (121), (c) a first synthetic jet actuator (111) equipped with a first diaphragm (162) which is adapted to vibrate such that it undergoes displacements along a first axis, and (d) a second synthetic jet actuator (113) equipped with a second diaphragm (163) which is adapted to vibrate such that it undergoes displacements in an opposite direction along said first axis from said first diaphragm.
