Exper ment s w ere l m ted by t he h g h temperature. In order t o st udy t he forced cool ng s t uat on of h gh temperature balk cargo, the numer cal s m ulat on was conducted on the opt m zed cool ng un t by us ng t he sof tw are Fluent. T he temperature d st r but ons of the cool ng process for graph t e w ere obta ned. T he result s showed that the nlet temperature of the cool ng un t s very h gh. T o prot ect t he cool ng un t, heat- res st ng mat er als are requ red. T he outlet t em perature falls to 324 K , w h ch s much low er than t he requ rement . T he cool ng eff ect s remarkable. Both of the out let t emperat ures of t he water n tw o st ag e cool ng un ts meet t he requ rement s. T here are n good agreement betw een the s mulat on result s and t he measurements. A ccord ng to the s mulat on results, the cool ng ef fect s tested and the furt her opt m zat on for the opt m zed cool ng un
