Structural Optimization Of The Heat Sink And Heat Sink For The Assembled Radiator Of The Vehicle

In this paper, numerical simulation part is the optimization of assembly type heat pipe type heat sink structure and structure parameters. Fin heat pipe was studied with four different structural parameters by numerical simulation method and eleven kinds o f different structure parameters on the temperature and pressure characteristics, analysis of the results to obtain the optimal structure parameters.(1) In this paper, First make a reasonable simplification for the model of waist tube, flat tube and elliptical tube radiator, then the heat dissipation unit is modeled, divided into grid and numerical simulation. respectively with different inlet velocity condition variables, through the distribution of the pressure, velocity, temperature and heat transfer in contrast four sets of heat radiating unit, find out the 2# tube is higher than that of the other three kinds of heat sink.(2) In the process of optimizing the structure of the heat sink, it is based on the foundation of the heat dissipation tube is the optimal structure of the tube type. First establish heat dissipation model of several different window opening a ngle, in order to find the best angle; And then the optimal angle is set as the angle of the shutter in the model, to optimize the fin spacing;at the last, get optimal louver window angles and fin spacing is known to establish different sizes of fin thick ness model and find the optimal fin thickness values.Finally, it is concluded that when the tube is 2#, the heat sink is 23 degree, the fin spacing is 0.9mm and the fin thickness is 0.10 mm, the heat dissipation effect of the radiator is the best.(3) Through the wind tunnel experiment of different tube type heat radiator, the heat transfer of the heat transfer tube radiator of 2# is 13.4%, and the error of the simulation results is 5.5%.
