Abstract (en)

[origin: DE19652999A1] The heat accumulator block has a dirt pan (6) consisting of a plurality of guard plates (12) which are placed substantially parallel to one another in order to form flow channels, and are fastened by their lateral walls (13) to a holding device (14). Adjacent guard plates (12) are held separated but fastened to each other by spacers (15). The spacers (15) are so arranged that they lie on the face against which the cold medium flows, at a distance from the front-side edges of the guard plates (12). This reduces the formation of sediment in the area of these edges. Furthermore, the guard plates (12) consist of elastically ductile synthetic material and have an undulated profile. Their motivity under vibration and thermal expansion promotes the flaking of sediment.
