Abstract
A handheld device may include a magnetic convection cooling system, which may include a fluid chamber that is in thermal communication with electronic circuitry of the handheld device. The fluid chamber may be closed and may contain a substantially non-gaseous first fluid and a substantially non-gaseous second fluid, wherein first fluid may include a magnetic property different from a magnetic property of second fluid. At least one electromagnet may be selectively activated to move the first and second fluids within the fluid chamber to provide convective cooling of the electronic circuitry.
Claims14
A handheld device, comprising:
- a first fluid and a second fluid that are substantially non-gaseous and within a fluid chamber that is in thermal communication with electronic circuitry, wherein the first fluid includes a magnetic property different from the second fluid;
- a first electromagnet positioned at a first side of the fluid chamber;
- a second electromagnet positioned at a second side of the fluid chamber;
- a temperature sensor that is in thermal communication with a component of the electronic circuitry;
- and
- control circuitry in communication with the temperature sensor, wherein the control circuitry is to:
- determine whether a temperature of the component exceeds a threshold temperature;
- and
- alternate activation of the first electromagnet and the second electromagnet in response to determination that the temperature of the component exceeds the threshold temperature, wherein the first fluid and the second fluid are to change locations based on the alternate activation.
A handheld device, comprising:
- electronic circuitry;
- a fluid chamber in thermal communication with the electronic circuitry;
- a means for determining a temperature of a component of the electronic circuitry;
- a means for cooling a portion of the handheld device, wherein the means for cooling includes a first substantially non-gaseous fluid and a second substantially non-gaseous fluid contained within the fluid chamber;
- a means for positioning the means for cooling within the fluid chamber, wherein the means for positioning includes a first electromagnet positioned at a first side of the fluid chamber and a second electromagnet positioned at a second side of the fluid chamber;
- and
- a means for activating the means for positioning, wherein the means for activating is to:
- determine whether the temperature of the component exceeds a threshold temperature based on an output of the means for determining;
- and
- alternatively activate the first electromagnet and the second electromagnet to reposition the means for cooling in response to determination that the temperature of the component exceeds the threshold temperature, wherein the first fluid and the second fluid are to change locations based on alternate activation of the first electromagnet and the second electromagnet.
