Abstract
A piezoelectric cooling system and method for driving the cooling system are described. The piezoelectric cooling system includes a first piezoelectric cooling element and a second piezoelectric cooling element. The first piezoelectric cooling element is configured to direct a fluid toward a surface of a heat-generating structure. The second piezoelectric cooling element is configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.
Claims19
A cooling system comprising:
- a first piezoelectric cooling element configured to direct a fluid toward a surface of a heat-generating structure;
- and
- a second piezoelectric cooling element configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.
A piezoelectric cooling system, comprising:
- a first plurality of cells, each of the first plurality of cells including a chamber, a first piezoelectric cooling element, a plurality of orifices distributed on at least one surface of the chamber and a valve, the first piezoelectric cooling element directing a fluid toward a surface of a heat-generating structure, wherein a vibrational motion of the first piezoelectric cooling element causes an increase or decrease in a volume of the chamber as the first piezoelectric cooling element is deformed, the plurality of orifices allowing escape of the fluid from within the chamber during the decrease in the volume in response to the vibration of the first piezoelectric cooling element, the valve being configured to admit the fluid into the chamber when the volume increases and to substantially prevent fluid from exiting the chamber through the valve when the chamber volume decreases;
- a second plurality of cells, each of the second plurality of cells including a second piezoelectric cooling element configured to direct the fluid to an outlet area after heat has been is transferred to the fluid by the heat-generating structure;
- and
- a plurality of exhaust chimneys interposed between the first plurality of cells, allowing fluid exiting the chamber from the plurality of orifices to be transported away from the plurality of orifices toward the outlet area.
A method of cooling a device comprising:
- is selectively driving a first piezoelectric cooling element configured to direct a fluid toward a surface of a heat-generating structure;
- and
- selectively driving a second piezoelectric cooling element configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.
