NOVELTY - The utility model claims a heat-resistant steel volute for turbocharger, relating to the field of turbocharger, comprising an inner shell and an outer shell; the bottom end of the inner shell and the outer shell is provided with a connecting base; the connecting base is fixedly connected with the inner shell and the outer shell; the outer side wall of the inner shell fixedly connected with with a heat conducting plate; one side of the heat conducting plate close to the inner shell fixedly connected with with a plurality of heat conducting columns distributed at equal intervals; the heat conducting column is embedded in the inner shell. The utility model through the inner shell is provided with a heat conducting plate and a heat conducting column; the heat conducting column transfers the heat received by the inner shell to the inner part of the heat conducting plate; then the heat is radiated to the outer side of the outer shell by a plurality of radiating fins on the heat conducting plate, so as to improve the radiating effect of the volute; The graphene radiating layer is set on the inner side wall of the outer shell body, which avoids the heat accumulation in the outer shell body, improves the radiating effect of the outer shell.
