US 6,145,582 A · Heat accumulator block for regenerated heat exchanger

Abstract

A heat accumulator block for regenerative heat exchangers has a heat exchanger of a plurality of heat exchanger plates arranged substantially parallel to one another for formation of flow channels. A dirt collector is arranged upstream of a side of the heat exchanger exposed to an inflowing cold medium. The dirt collector consists of a plurality of protective plates which are arranged substantially parallel to the heat exchanger plates and have a plurality of spacers. The spacers are arranged between neighboring plates and connect the neighboring plates to one another. The spacers are positioned at a spacing to those edges of the protective plates which are exposed to an inflowing cold medium.
