Abstract

A stacked plate heat exchanger may include a plurality of stacked plates stacked on top of one another, between which a plurality of hollow spaces for two media may be alternately defined. The plurality of stacked plates may include at least two first stacked plates and at least one second stacked plate. The plurality of stacked plates may respectively include at least one first passage opening surrounded by a dome and at least one second passage opening. The at least one second passage opening of the at least one second stacked plate may be surrounded by an annular bead. The at least one second stacked plate may be arranged between the at least two first stacked plates such that the dome of a lower first stacked plate, the dome of an upper first stacked plate, and the annular bead are connected to one another and define an immersion tube.
