Abstract:
A device that includes a region comprising an integrated device, and a heat dissipating device coupled to the region comprising the integrated device. The heat dissipating device is configured to dissipate heat away from the region. The heat dissipating device includes a fluid, an evaporator configured to evaporate the fluid, a condenser configured to condense the fluid, an inner wall coupled to the evaporator and the condenser, an outer shell encapsulating the fluid, the evaporator, the condenser and the inner wall, an evaporation portion configured to channel an evaporated fluid from the evaporator to the condenser, and a collection portion configured to channel a condensed fluid from the condenser to the evaporator. The heat dissipating device includes one or more piezo structures configured to move fluid inside the heat dissipating device.
