摘 要：To explore the relationship between the supply air rate and the resistance of the cooling module itself,this paper provides a simulation method for cooling front module andsingle cooler supply air rate and wind *** the matching method,the monomer with the same characteristic structure is simplified to porous medium,and its characteristic parameters are obtained,the CFD is used to simulate the problem,and the accuracy is verified by the test;and the wind speed-resistance characteristics are simulated by the super position of multiple monomers,and the results are *** method can accurately predict the wind resistance of the cooling system during the design stage,and provide a basis for the selection of the scheme.
