Abstract
A rotary machine for conveying a fluid includes a drive unit configured to drive a shaft, an impeller arranged at the shaft, and configured to convey the fluid, at least one mechanical seal configured to seal the shaft, a first and a second heat exchange system configured to cool or heat the mechanical seal, the first heat exchange system configured for direct application of a fluid heat carrier at the mechanical seal and the second heat exchange system comprising a heat exchange jacket capable of having a fluid heat carrier flow therethrough without direct contact with the mechanical seal, the first and the second heat exchange systems forming a common heat exchange system in which a common fluid heat carrier is capable of being circulated, and a fan wheel configured to circulate the common fluid heat carrier in the common heat exchange system.
