A plate heat exchanger includes a stack of plate pairs with gaps between adjacent pairs, arranged to provide flow paths for a first fluid to pass through inner volumes of the plate pairs while simultaneously allowing a second fluid to flow over the outer surfaces of the plate pairs. At least one cylindrical fluid manifold for the first fluid extends through the plate pairs. A non-planar cap is arranged at one end of the plate heat exchanger to close off the cylindrical fluid manifold. A reinforcement plate is arranged at that end between the non-planar cap and an end plate of the plate heat exchanger. The position of the non-planar cap relative to a central axis of the cylindrical fluid manifold is maintained in order to prevent failure of the plate heat exchanger due to internal pressurization. 一种板式热交换器，包括板对的堆叠件，其中在相邻的板对之间具有间隙，板对的堆叠件被布置成用以提供用于使第一流体穿过板对的内部容积的流路，同时允许第二流体流过板对的外表面。用于第一流体的至少一个圆柱形流体歧管延伸穿过板对。非平面盖布置在板式热交换器的一端处，以封闭圆柱形流体歧管。加强板布置在所述一端处在非平面盖与板式热交换器的端板之间。非平面盖相对于圆柱形流体歧管的中央轴线的位置被维持以便防止由于内部增压而导致板式热交换器的故障。
