The thermal resistance of a spin-polarized hydrodynamic Dirac plasma in graphene is considered. Here, a mechanism for the coupling of heat and spin flows is discussed, demonstrating that spin diffusion and spin thermocurrent modify viscous dissipation, leading to a significant enhancement of thermal resistance. Practical calculations are then presented for graphene devices in the Corbino geometry.
