Abstract: A seal rotor which can include a plurality of fluid inlets on the exterior. The fluid inlets can draw fluid into the body of the seal which can assist in removing heat from the primary sealing interface, thereby reducing thermal deformation of the sealing interface with its non-rotating counterpart. The seal rotor configuration allows fluid to flow through the seal rotor and keep the seal rotor closer to an isothermal state than a prior art seal rotor. The seal's body can additionally include a series of fins on the inside of the body. The fins define channels through which fluid entering via the fluid inlets can flow. These features function as a system for spreading and dissipating the heat of the system.
