摘要
With the increase of power density of electronic components, in order to prolong their lifetime, developing cooling schemes with high heat dissipation performance has attracted much attention. The hybrid cooling schemes, combing the merits of microchannel and microjet, have been widely studied in the past decades. However, there is no good solution to the dilemma of blockage caused by multi jets, which weakens the heat dissipation performance of cooling schemes. In this study, a new hybrid cooling scheme was proposed, introducing coolant by microchannel to attenuate the vortex in order to improve heat transfer performance, and the heat flux of single-phase flow reached 233 W/cm2. A test module was constructed and tested using the deionized water as the coolant. A superposition technique was developed further, which now could correlate the single-phase heat transfer data for a new hybrid cooling scheme successfully, with all data falling within 95% confidence band. These findings have an impact on the further development of efficient cooling technology.
