Integration of active mems cooling systems into smart phones

A mobile phone, comprising:

• a cover defining an interior portion of the mobile phone;
• a circuit board to which a heat-generating structure is coupled, the circuit board being within the interior portion;
• a cooling system including at least one active cooling cell, the heat-generating structure being thermally coupled with the cooling system, the at least one active cooling cell being configured to utilize vibrational motion to drive a fluid for transferring heat from the heat-generating structure, the cooling system being contained by the cover;
• and
• wherein at least one of the mobile phone includes an interposer, the cover includes a raised portion, or the mobile phone includes a cavity therein, the interposer being coupled to the circuit board and including a gap configured such that a first portion of the cooling system thermally coupled with the heat-generating structure resides within the gap, the raised portion of the cover being configured such that a second portion of the cooling system resides in the raised portion, the cavity including the cooling system therein, separating the cooling system from the interior portion of the mobile phone, and configured such that the interior portion is water resistant.
