Abstract:In order to improve the heat dissipation capacity of the electronic equipment system of the near space vehicle and solve the problem of high heat flux of integrated and miniaturized electronic devices,the paper had a study on the heat transfer performance of dual synthetic jets actuators, by making use of two-phase flow composed of micron-particle and water and their combination. The mechanism of enhancing heat transfer capacity with dual synthetic jets actuator is was studied and analyzed. The flow process of the dual synthetic jets actuator and Cu-water micron particle fluid in the tube is was modeled, and the influence of five particle concentrations on the enhanced heat transfer capacity of the fluid is was simulated by the single Euler model. CUO-water and Al2O3-water micron particle fluids are were simulated. The results show that the heat transfer capacity of fluid can be enhanced by the dual synthetic jets. The heat transfer capacity in-creases with the increase of micron particle concentration. The two-phase flow heat transfer capacity of different metal particles varies with the thermal conductivity of metal particles. In the example, a microparticle fluid of Cu particles with a dual synthetic jets actuator on and a particle concentration of 8% is synthesized, and the chip temperature is reduced from 328.225K to 303.816K.
