عنوان المقالة:دراسة عملية و عددية لصفيحة مبرة في ظروف تشغيلية مختلفة An Experimental and Numerical Study the Performance of Finned liquid Cold-Plate with Different Operating Conditions
The temperature is the most important thing that
limits the electronic devices applications around the world.
All of them need to be cooled under particular
temperature to be safe. During the history there are many
applications have been used for this purpose, such as coldplate,
which is considered one of them. One type of these
cold-plates has been investigated experimentally and
numerically in this study. Experimentally, the finned coldplate
is tested with different values of water flow rates and
inlet temperatures. In the numerical study, the STAR
CCM+ program is used by depending on the values of
water flow rates and inlet temperatures in experimental
tests. A comparison between these two approaches has
been made.
According to the results, there is agreement
between experimental data and numerical solution. Also,
the flow rate effect gives that, it has a slight effect on fin
temperature gradient, where the average change in coldplate
base temperature does not overstep 2%. In addition
to fin temperature distribution, water inlet flow rates
affect the water temperature along its slot, it can be
noticed that decreasing rate of water temperature has
inversely proportional with water flow rate. In-spite of this
proportional, the turbulent flow rate leads to dissipated
more energy than laminar flow rate, but the problem
should be encountered is that pressure drop might be
duplicated through this turn of flow rate. Furthermore,
the average change of dissipated power within laminar or
turbulent state only is not considerable.
