Abstract
Heat exchanger or heat accumulator bodies which are simple to produce. The bodies consist of a stack of extruded hollow chamber panels with plane smooth outer walls and webs that join the outer walls in a single piece. The hollow chamber panels are joined to one another in the stack on the front side by locking connections. The locking connections can be produced with an inserted electrical band heater, by glue seams, or by undercut interlockings. The hollow chamber panels are not joined to one another in the in-between areas or are not everywhere joined in the in-between areas.
