摘要：
A system (50) includes a material layer (52) having an opening (62) extending through it and a pumping device (54) positioned behind the layer (52). A target element (56) is positioned in front of the material layer (52). In a partial cooling mode (124), the pumping device (54) drives a jet (134) of coolant through the opening (62) toward the target (56). Transducers (58, 60), positioned at opposing ends of the opening (62), produce output signals (130, 132) that perturb the jet (134) to partially control its oscillation. The jet (134) spreads from a location (96) on the target element (56) in one direction (142) to provide uniform cooling over a portion (126) of the target element (56) in the direction (142), and the jet (134) non-uniformly spreads in another direction (144) to provide non-uniform cooling over a portion (128) of the target element (56) in the other direction (144).
