Abstract
A mobile device, such as a mobile phone, including a housing and active cooling cells is described. The active cooling cells are in the housing. The cooling cells utilize vibrational motion to drive a fluid such that the mobile phone has a coefficient of thermal spreading (CTS) greater than 0.5 for a steady-state power generated by the mobile phone of at least five watts.
Claims16
A mobile phone, comprising:
- a housing;
- a plurality of active cooling cells in the housing, each of the plurality of active cooling cells including at least one cooling element configured to undergo vibrational motion to drive a fluid for transferring heat from a first heat-generating structure in the mobile phone such that the mobile phone has a coefficient of thermal spreading (CTS) greater than 0.5 for a steady-state power generated by a second heat-generating structure of the mobile phone of at least five watts.
A mobile device, comprising:
- a housing having at least one dimension with a length of not more than twenty-five millimeters;
- a cooling system including a plurality of active cooling cells residing in the housing, each of the plurality of active cooling cells including at least one cooling element configured to utilize vibrational motion to drive a fluid for transferring heat from a first heat-generating structure in the mobile device for a steady-state power generated by a second heat-generating structure of the mobile phone of at least five watts.
A method for cooling a mobile device having a housing, the method comprising:
- driving a plurality of active cooling cells in a cooling system residing in the housing, each of the plurality of active cooling cells including at least one cooling element configured to undergo vibrational motion to drive a fluid for transferring heat from a first heat-generating structure in the mobile device such that the mobile device has a coefficient of thermal spreading (CTS) greater than 0.5 for a steady-state power generated by a second heat-generating structure of the mobile phone of at least five watts.
