Sažetak

The article demonstrate significance
of radiation heat transfer on cooling
performance of radiators used in power
transformers with air natural cooling
configuration using analytical calculations
and computional fluid dynamics
simulations on two different case
studies. Convective and radiative heat
transfer mechanisms are modelled on
a single radiator and a good agreement
with the experimental measurement
results is observed. The radiation contributes
21.3 % of total heat dissipation
and thus has a significant impact on
overall heat dissipation and cannot be
neglected. This study will be useful –
for the transformer designer – to point
on the relevance of the radiative heat
transfer in cooling.
