Abstract

In this article the short review of the problem of cooling high-power electronic components by impinging jets at various initial conditions is presented. Experiments of researching the heat emission for boiling R-134a on microribbed and microroughed surfaces at the conditions of stationary heating are made. Graphics of dependences of density of the heat flux on distance between the channel and the effective surface are presented. Influence of the form of the channel on the temperature profile is positioned.
