Porous media conditions: model parameter method of porous media for calculation. The numerical simulation result table lists the simulation data of the heat sink with the wave distance of the heat dissipation band. The radiator simulation data shows the numerical simulation results of the overall temperature field of the tube-belt radiator when the wave distance of the heat dissipation belt is at the water inlet flow rate and the air inlet speed. Result comparison and conclusion analysis The error comparison between the experimental data and the simulation results of the radiator with a wave distance of the heat sink The distance radiators have been processed as shown in the table.
The numerical simulation results of the radiator are in good agreement with the wind tunnel test data, where the maximum error of the outlet water temperature is and the maximum error of the wind resistance is. The errors between the test data and the simulation results mainly come from two aspects. On the one hand, the inevitable errors caused by the test equipment, test methods, and data collection in the heat transfer wind tunnel test of the radiator are caused by the radiator numerical simulation. Errors caused by assumptions and simplifications in the calculation of its physical model. Although there are certain errors, the accuracy of this simulation algorithm can already meet the needs of actual engineering, and it has certain reference value for the future research on the fluid flow and heat transfer mechanism inside and outside the tube-belt automotive radiator. Performance comparison of double drain pipe and single drain pipe radiator. Simulation results. The core of double drain pipe radiator is made of aluminum; the core is high, the air inlet speed, the water flow rate, the water temperature, the water temperature, the air temperature, the air temperature, and the heat dissipation. Wind resistance temperature, inlet air speed, inlet water flow rate test, outlet water temperature simulation, outlet temperature error test, wind resistance simulation wind resistance error year, width and thickness respectively; the number of heat dissipation water pipes is; the number of heat dissipation bands is the double drain pipe type heat dissipation water pipe row is row, water pipe The outer side is wide, the wall of the water pipe is thick, and the water pipe is long; the wave height, wave distance, and thickness of the heat dissipation belt are as follows. The window opening angle of the heat dissipation belt is simulated and calculated using the proven and reliable simulation algorithm for the double drain pipe radiator.
