Battery liquid cooling device and method based on vibration strengthened phase change

Abstract

The application discloses a battery liquid cooling device and method based on vibration strengthened phase change, which comprises a sealed box body containing cooling liquid, a battery, a vibration assembly, a controller, a gas cavity is arranged between the upper surface of the cooling liquid and the top wall in the sealed box body, the battery is detachably installed in the sealed box body and is immersed in the cooling liquid, the vibration assembly is arranged at the bottom outside the sealed box body, a pressure sensor is installed on the top surface in the sealed box body, one end of a pressure regulating pipeline is communicated with the gas cavity of the sealed box body, the other end is connected with the inlet of a condenser, the outlet of the condenser is connected with a circulating water pipeline, and the circulating water pipeline is communicated with the bottom of the sealed box body. The vibration assembly is used for applying periodic mechanical vibration to the sealed box body, actively destroying the thermal boundary layer on the surface of the battery, synchronously strengthening the vaporization and condensation phase change processes of the cooling liquid, and forming a vibration and phase change coordinated heat transfer enhancement mechanism.
