Claim 13:
14. 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, the device further defining surfaces of at least one exit channel, the at least one exit channel sharing surfaces with, and extending circumferentially about, a perimeter of the plenum chamber, wherein the plenum chamber comprises four side walls, the four side walls also forming side walls of the at least one exit channel, the at least one 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 at least one exit channel being provided on a second side of the side walls such that the at least one exit channel extends circumferentially, about a perimeter of the plenum chamber, the at least one 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, wherein the plenum chamber is dimensioned to operably form a pressurised chamber such that fluid flow entering into 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, wherein the plenum chamber defines a first stagnant chamber and the at least one exit channel defines a second stagnant chamber.
