根据本发明的板式热交换器包括至少一个用于接收至少一种第一例如发热流体的第一流体空间以及用于接收至少第二例如吸热流体的至少一个第二流体空间。 流体限制壁用于将流体空间彼此分离和/或从外部环境分离。 至少一个流体限制壁包括弹性材料，或者特别是由弹性材料形成。

The plate heat exchanger according to the invention comprises at least one first fluid chamber for receiving at least one first heat-dissipating fluid, for example, and at least a second fluid chamber for receiving at least a second heat-absorbing fluid, for example. Fluidbegrenzende walls serve to separate the fluid chambers from one another and / or against an external environment. At least one of the walls delimiting the fluid comprises a resilient material, respectively is formed, in particular of an elastic material.
