摘要

In a pack of rectangular plates to be used in a regenerative heat exchanger the plates are kept in position by a plurality of mutually parallel tension rods passing through registering openings in the plates. Each tension rod has at its ends securing means co-operating with the outer plates of the stack for holding the plates pressed against each other. At least one of the tension rods is provided with a lifting eye device which can be moved into the pack and out of the pack, respectively.
