| Popis: | A novel microfluidic cooling solution, based on a microfluidic cell array with self-adaptive valves, for efficient cooling of time-varying and non-uniform heating in microelectronics. The proposed cooling device is formed by an array of microfluidic cells, each one responsible for removing the local heat flux. Coolant flow is fed in parallel to the cells by interdigitated cold and warm flow channels connected to manifolds. Each cell, therefore, has a cold inlet flow, irrespective of its location. Heat is removed by the flow through microchannels enclosed in the cells. Each cell integrates a self-adaptive micro-valve capable of tailoring the local flow rate to the local cooling needs. In this paper, the actuation of self-adaptive valves, placed in each cell of an array of 6 by 10 microfluidic cells, is experimentally demonstrated. Also, the performance of the microfluidic cell cooling system is assessed and compared with regular microchannels, under a non-uniform and time dependent heat load, in order to identify the benefits of this novel microfluidic cooling solution. |
