Numerical Simulation Of Fin Oscillating Heat Pipe Heat Shtrengthened

With the need of science and society, the development of electronic products was become more and more miniaturization and integration. To increase the performance of electronic products, it will grow the power and heat of products. Operating temperature will has a deeply influence on the normal operation of the electronic products. From the display of relevant information, the failure of more than 55% of the electronic component was due to the high temperature. Therefore, the heat issue has become a key issue of continued development and the stable operation to electronic products. Oscillating heat pipe transfer heat by using its own working fluid phase change.It has a simple structure, good thermal conductivity, no moving parts, high reliability advantages. Oscillating heat pipe is a great potential for heat transfer components in cooling of microelectronic components. Therefore, the oscillating heat pipe research is very necessary.The paper was based on the integration of existing literature. We use the ANSYS to do the simulation of the heat pipe, according to the start-up performance and heat transfer performance of heat pipe oscillation. Based on the theory and working conditions, we accomplished the simulation model of oscillating heat pipe. Simulate the oscillating heat pipe process from the initial to the stable operation. At 60% of the filling rate, research the oscillating heat pipe with different working fluid Research oscillating heat pipe Finned radiator, simulate the radiator in different fin pitch, size, work hole location. The results are as follows: Observed the process of heat pipes running gas-liquid two-phase diagram changes. Shows the flow pattern inside the heat pipe bursting bubbles merge changes and other phenomena, Close the literature. The physical properties of the working fluid can affect Startup characteristics, heat and mass transfer. Obtained temperature distribution on the fin surface under different working conditions. Analyze the relationship between different factors and radiator performance and optimize radiator.
