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.　©　2022　by　Begell　House,　Inc.
