Research on heat transfer optimization of heat sink based on phase change isothermal technology for deep hole drilling machine
Based on the phase change isothermal technology for deep hole drilling machine
a research methodology involving numerical simulation and experimental testing was applied to optimize the heat transfer design of a heat sink for a rail transit project with non-uniform heat flux density and multiple integrated heat source devices in its thermophysical field. First of all
a comparison was made on the temperature rise performance of heat sinks with phase change isothermal technology for deep hole drilling machine in different installation directions
the fluctuation range under different working conditions is only 1.6%-3.4%
showing a small difference
indicating that the heat transfer process of the working medium inside the heat sinks with phase change isothermal technology for deep hole drilling machine had good anti-gravity characteristics. Secondly
the performance of the newly designed and optimized heat sinks with phase change isothermal technology for deep hole drilling machine was compared with that of the conventional finned heat sink of the same size. The results show that the temperature rise of heat sinks with phase change isothermal technology for deep hole drilling machine can be reduced by 6.0-14.3 K
with a reduction rate of 10.9%-13.8%
compared with conventional finned heat sink under the same working conditions. The maximum reduction in the average temperature is 26.3 K
with a maximum reduction rate of 53.3%
and both the temperature rise control and the average temperature are greatly improved
indicating that the application of phase change isothermal technology for heat dissipation of deep hole drilling machine in thermophysical fields with non-uniform heat flux density and multiple integrated heat source devices can yield significant heat dissipation advantages.
