交換器のシール装置。 A low-temperature fluid passage on the upstream side of the heat storage body is opened in a housing that accommodates a heat storage body that is freely rotatably interposed in both the high-temperature fluid passage and the low-temperature fluid passage, and is connected to both sides of the heat storage body. At the end of the high temperature fluid passage and at the end of the low temperature fluid passage on the downstream side of the heat storage element, a sealing device for preventing fluid mixing is provided which presses and presses the heat storage element in a freely sliding manner.
In a rotary regenerative heat exchanger that performs heat exchange between fluids, a sealing member is attached to the side surface of the heat storage body via an elastic member at least at the end of the low temperature fluid passage on the downstream side of the heat storage body and the end of the high temperature fluid passage on the upstream side of the heat storage body. 1. A sealing device for a rotary regenerative heat exchanger, characterized in that the sealing device is attached to the rotary regenerative heat exchanger so that the sealing member can be moved toward and away from the heat exchanger, and further includes a sealing member driving means for separating the sealing member from a side surface of the heat storage body when the engine operation is stopped.
