Abstract
A quick release mechanism for a sprinkler head comprises a frangible element and a heat expansible fluid contained therein. A thermally conductive element or heat sink extends through a wall of the frangible element. A portion of the heat sink is in contact with the expansible fluid and another portion of the heat sink is disposed outside the wall. The heat sink conducts heat from the outside of the frangible element to the heat expansible fluid within so as to accelerate expansion of the fluid and rupture of the frangible element.
