Abstract
The present invention relates to a sealing device for minimizing leakage losses in a rotary regenerative type heat exchanger, and more particularly in a heat exchanger comprising a cylindrical matrix of heat absorbent material rotatably mounted in a stationary housing. To prevent a loss of efficiency of the heat exchanger, which occurs when an uncontrolled flow between the inlets and the outlets of the exchanger takes place, an axially extending annular groove (3) having bottom and side walls is formed in each of the two end surfaces (2) of the matrix (1). In each of these annular grooves (3) a stationary sealing sleeve (5) projects into each of said grooves.
