Claim 0:
1. A liquid cooled thermal heat sink device comprising a housing having a fluid inlet and a fluid outlet, the fluid inlet being in fluid communication with a plenum chamber, the plenum chamber comprising a jet orifice plate which defines a plurality of jet orifices through which a pressurised liquid can operably exit the plenum chamber and contact a thermal surface, wherein the jet orifice plate defines a base of the plenum chamber, the plenum chamber further comprising side walls extending upwardly from the base, the device further defining surfaces of an exit channel, wherein the exit channel shares the side walls with the plenum chamber, the plenum chamber being provided on a first side of the side walls and the exit channel being provided on a second side of the side walls such that the exit channel extends circumferentially about a perimeter of the plenum chamber, the exit channel being configured to deliver fluid exiting the jet orifices to the fluid outlet, the fluid inlet being perpendicularly offset from the jet orifices, and wherein the plenum chamber is dimensioned to operably form a pressurized chamber, such that fluid flow entering the chamber is stagnated and then exits the chamber via each of the plurality of jet orifices at a constant flow rate, the flow rate exiting the chamber being greater than the flow rate entering the chamber, and wherein the plenum chamber defines a first stagnant chamber and the exit channel defines a second stagnant chamber.
