ABSTRACT:
A seal assembly for providing seal between an end face of a cylindrical and rotatable heat-transferring member and an opposite surface of a stationary member of the heat exchanger, having a loop-shaped and cross-sectionally rectangular seal member of a heat-resistant and rigid material, a loop-shaped groove formed in the surface of the stationary member to loosely receive the seal member, a loop-shaped back-up member of a resilient material tightly received in the bottom of the groove such that the seal member is sandwiched with a compressive force between the back-up member and the end face of the heat-transferring member, and a loop-shaped auxiliary seal member of a resilient material arranged to provide seal between the outer surface of the seal member and the outer wall of the groove and press the seal member against the inner wall of the groove.
