Paper Abstract

Experimental studies of impinging liquid jet-array cooling modules are described. Heat fluxes have reached 7.2 MW/m2 over an area of 10.3 cm2. Heat loads are applied to a metallic faceplate by a plasma-sprayed resistance heater. Faceplates are a few millimeters thick and area made from either copper or molybdenum alloys. The faceplate is cooled by an array of 14 small diameter water jets operating at speeds of 46 m/s. Cooling is believed to be entirely convective, without boiling. The construction of the plasma sprayed heaters presents several challenges, including unpredictable thermal and electrical properties, high thermal resistances, and fracture at high temperatures. Thermal resistances are quantified and our experience with the heaters is described.
