During climb out; the Left Pack Trip Off illuminated. We consulted the QRH and cleared the Master Caution light. Prior to reaching the cruise altitude of FL370; the Left Pack Trip Off illuminated again followed by the Right Pack Trip Off. We immediately donned our oxygen masks and informed ATC we were performing an emergency descent. The Captain was flying and told ATC we wanted to divert to an airport which was close to our en route position. After completing the QRH; we coordinated with Dispatch and it was determined we were going to land overweight at approximately 134;000 LBS. We declared an emergency with ATC; informed the flight attendants and the passengers. We landed overweight without incident. The emergency personnel standing by inspected the brakes before we continued the taxi to the gate.

A B737-700 Left Pack Tripped Off during climb but reset. It tripped again at cruise; followed by the Right Pack Trip; so an emergency was declared and the flight diverted to a nearby airport.
