Mobile device case including an active cooling system

A mobile device case, comprising:

• a housing for retaining a mobile device, a portion of the housing into which an active cooling system is integrated having a thickness not exceeding three millimeters;
• and
• the active cooling system integrated into the housing, the active cooling system having a depth not exceeding two millimeters, the active cooling system configured to cool a surface of the mobile device, the active cooling system further including an orifice plate having at least one orifice therein, a top plate having at least one vent therein, and a cooling element in communication with a fluid, the cooling element being configured to use vibrational motion to direct the fluid to be incident on the surface of the mobile device, the cooling element being between the orifice plate and the top plate, the cooling element configured to undergo the vibrational motion when actuated to draw the fluid into the at least one vent, direct the fluid toward the orifice plate, and drive the fluid through the at least one orifice.

A method, comprising:

• driving a cooling element of an active cooling system at a frequency to induce a vibrational motion, the active cooling system being integrated into a housing of a mobile device case, the housing configured to retain a mobile device, the active cooling system including an orifice plate having at least one orifice therein, a top plate having at least one vent therein, and the cooling element between the orifice plate and the top plate, the cooling element configured to undergo the vibrational motion when driven at the frequency to draw a fluid into the at least one vent, direct the fluid toward the orifice plate, and drive the fluid through the at least one orifice.
