Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | In this paper, the hollow heat sink has been studied. The physical and
mathematical model of a hollow heat sink and CFD modeling are proposed for fitting the
experimental results. It has been shown that the model of a hollow heat sink allows to
calculate the velocity (and temperature) of the air flow coming out of the hollow heat
sink, to determine its dependence on the angle of the dissipated thermal power, length,
and degree of fin and cross-sectional area of the hollow heat sink. The influence of the
geometry of the inlets/outlets on the heat removal was analyzed. It has been shown that
the efficiency of the quasi-active system increases significantly in the presence of
external wind through the so-called “effect of spray” |
