The aim of the of the planned research project is to develop a methodology and also production technologies for the design and manufacture of optimized secondary structures for pillow plate heat exchangers. These should have significantly improved application properties. Two focal areas of work thus result for the planned research. The first of these is the research and development of application-specific optimized structuring, which should be carried out against the background of easy producibility of the structures. A method is to be developed to this end for thermohydraulic multi-scale modelling on the basis of CFD models which can be used for the reliable determination of optimised pillow plate secondary structures for specified application cases. The second focal area, which is closely interlinked with the first one, consists in developing a manufacturing technology that is suitable for introducing optimised secondary structuring into sheet metal semi-finished products. It should be possible in particular to produce very fine contours having small radii, with a simultaneously high surface quality and also shape and dimensional accuracy, in a reliable process. This should be cost-efficient especially for components produced in small quantities. Incrementally-applied electrohydraulic forming is a promising approach here. In order to further develop this method for the processing of larger-area sheet metal semi-finished products suitable for pillow plate heat exchangers, appropriate FEM models are to be created and elaborated on the basis of these tools (tool systems) and process control or process control strategies.

计划中的研究项目的目的是开发一种设计和制造枕板式换热器优化二次结构的方法和生产技术。这些应该会显著改善应用程序属性。因此，计划中的研究有两个重点工作领域。首先是针对特定用途的优化结构的研究和开发，这是在结构易于制造的背景下进行的。为此，将开发一种基于CFD模型的热液多尺度建模方法，该方法可用于针对特定应用情况可靠地确定优化的枕板二次结构。与第一个密切相关的第二个重点领域在于开发一种适合于将优化的二次结构引入板材半成品的制造技术。特别是应该可以在可靠的工艺中产生具有小半径、同时具有高表面质量以及形状和尺寸精度的非常精细的轮廓。这应该是具有成本效益的，特别是对于小批量生产的零部件。渐进式电液成形是一种很有前途的方法。为了进一步发展这种适合于枕板式换热器的大面积板材半成品的加工方法，需要在这些工具(工具系统)和过程控制或过程控制策略的基础上建立适当的有限元模型并加以阐述。
