Micro-jet array impingement as a high heat flux cooling technology has potential application to a high power laser, micro-electronic clip and other high heat flux devices. The heat transfer characteristics of micro-jet array impinging on constant heat flux wall is simulated and analyzed in this paper. The cooling effect with both staggered and paralleled jet holes arrangement is compared, and finally the effects of jet Reynolds number, the distance of adjacent jet holes, impinging distance on cooling characteristics are studied.
