【Abstract】Byusing the calculation methodofone-dimensional-three-dimensional joint simulation，the influencesof AGS layoutformontheintakeairvolumeofthe front cabin，theheatdisipationof thecoling moduleandthe energy consumptionof theairconditioningcompressorwereexplored.Theresearchfinds thatwhenthedistancebetweenAGSblades andthegrilleis57～97mm，theeffectsof directandnon-directarrangementsonheatdissipationperformanceandenergy consumptiontendtobeconsistent.Theattenuationofintakeairvolumeisapproximately2.4%，thereductionofheatdissipation is lessthan1%，andthereisalmost no impactontheenergyconsumptionof thecompresor.When thedistance is lesthan 57mm（closetotegrlle），tedectaangementissuperiortohesaggeredarangemnt.Tisiseflectedinteactatthe intakeairvolumeincreasesby3.16%comparedtothestaggeredarangement，theeatdissipationincreasesbyapproximately 2% ，and the energy consumption of the compressor decreases by about 2% .When the distance is greater than 97 mm （close to thecolingmodule），theadoptionofastaggeredarrangementismoreconducivetoeducingtheairintakeatenuationcausedby AGS blades.
