| 摘要 |
The invention relates to a plate heat exchanger (11), whose parallel opposite walls (15, 17) are produced from sheet metal with a high thermal conductivity, preferably copper or aluminium. A reinforced border is configured around the connection points (13) in the surface of each of the sheets. This prevents the deformation by peeling of the sheet metal in the region of the connection points (13), in such a way that even soldered or glued connection points can withstand an increased internal pressure. |
