    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 heat transfer performance of the dual synthetic jets actuator, micron particle two-phase flow and their combination was studied. The mechanism of enhancing heat transfer capacity with dual synthetic jet actuator was studied and analyzed. The flow process of the dual synthetic jets actuator and Cu-water micron particle fluid in the tube was modeled, and the influence of five particle concentrations on the enhanced heat transfer capacity of the fluid was simulated by the single Euler model. Meanwhile, Cu-water, CuO-water and Al2O3-water micron particle fluids 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. When the micron particle fluid is a copper particle with a particle concentration of 8%, the chip temperature is reduced from 328.225 K to 303.816 K after the synthetic double-jet actuator is turned on.
