The Analysis of Thermal Field and Thermal Deformation of a Water-Cooling Radiator by Finite Element Simulation

A water-cooling radiator is the effective heat dissipation device to ensure the high-power electrical equipment work properly and the heat transfer process and thermal deformation of the water-cooling radiator become hot research areas currently. Based on a water-cooling radiator of a company, the simulation model for its single water-cooling flow channel is established and the influence of the flow velocity of the inlet fluid and thermal convection of air on the outlet temperature of fluid is analyzed by the commercial software ANSYS. In addition, the thermal deformation of the water-cooling flow channel is discussed. The simulation results show that the outlet temperature declines progressively as the inlet velocity increases, the outlet temperature goes downlinearly with the increase of coefficient of air convection. And the thermal deformation of the brass water-cooling radiator is obviously non-uniform and becomes warp inevitably.
