Abstract: A spiral heat exchanger includes a vessel, a plurality of concentric sheet metal spirals situated in the vessel and defining first and second spiral flow channels for respective first and second fluids for effecting a heat exchange therebetween; first and second closure plates extending perpendicularly to the vessel axis and covering the spirals at opposite spiral edges thereof; and mounting bars pressing the closure plates against axially opposite edges of the spirals. The first closure plate defines a first axially oriented opening and the second closure plate defines a second axially oriented opening providing, in the first flow channel, an inlet and an outlet for the first fluid. The vessel comprises a cylindrical vessel shell entirely surrounding the spirals. The first closure plate has a radially outer circumferential edge surrounded by the first axially oriented opening and the second closure plate has a radially inner circumferential edge surrounding the second axially oriented opening, whereby the first axially oriented opening communicates with a radially outer part and the second axially oriented opening communicates with a radially inner part of the first flow channel.

Abstract translation: 螺旋式热交换器包括容器，位于容器中的多个同心金属片螺旋，并且为相应的第一和第二流体限定第一和第二螺旋流动通道，用于在它们之间进行热交换; 第一和第二封闭板垂直于容器轴线延伸并以相对的螺旋边缘覆盖螺旋; 以及安装杆将密封板压靠在螺旋的轴向相对的边缘上。 第一封闭板限定第一轴向定向的开口，并且第二闭合板限定第二轴向定向的开口，在第一流动通道中提供用于第一流体的入口和出口。 容器包括完全围绕螺旋的圆柱形容器壳体。 第一封闭板具有由第一轴向定向的开口围绕的径向外周边缘，并且第二封闭板具有围绕第二轴向定向开口的径向内周边缘，由此第一轴向定向开口与径向外部部分连通， 轴向定向的开口与第一流动通道的径向内部部分连通。
