Abstract
A plate heat exchanger designed as a heat tube in the form of a multi-layer expanded partly laminated body has an integrated, fluidically continuous large-surface channel structure. Formed in the vicinity of the outer edge is a condensate-collecting channel which is fluidically connected unobstructedly to the channel structure. A heating bar or a heating channel is arranged near the edge separately but connected heat-conductively. To prevent condensate from flowing off on one side within the condensate-collecting channel as a result of gravity and/or horizontal acceleration and thereby to ensure the best possible heating effect, the condensate-collecting channel is subdivided into condensate pockets by a plurality of flow obstacles.
