A low temperature jet impingement based heat sink module has been developed for potential application in a near-term fusion power plant divertor. The design is composed of a number of hexagonal CuCrZrsheets bonded together in a stack to form a laminate structure. This method allows the production ofcomplex flow paths using relatively simple manufacturing techniques. The thermo-fluid performance ofa baseline design employing cascade jet impingement has been assessed and compared to a non-cascadecase. Experimental validation of the numerical work was carried out on a scaled model using air as theworking fluid. Local heat transfer coefficients were obtained on the surface using surface temperaturedata from thermochromic liquid crystals.
