Solution Overview
Problem
Current heat transfer plates for plate heat transformers face challenges in achieving high heat exchange efficiency and low flow resistance while minimizing the risk of fouling and maintaining structural integrity.
Innovation Solution
The heat transfer plate design features structural elements arranged in concentric paths, particularly circular railways, on a flat envelope with a base plate, allowing for efficient guidance of working media between inlet and outlet areas, made from heat-conductive materials like stainless steel, with specific arrangements to promote counter-current or cross-flow principles and mirror symmetry for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If structural elements are arranged in conventional patterns on heat transfer plates, then the plate can guide working media from inlet to outlet, but heat exchange efficiency is limited and flow resistance increases
Solution Approach 1:
The structural elements are arranged along concentric circular paths around a reference point in the inlet or outlet area, creating a radial flow pattern that improves heat exchange efficiency while reducing flow resistance compared to conventional linear arrangements
Solution Approach 2:
The invention transitions from conventional linear or grid patterns to a two-dimensional radial concentration pattern, with all structural elements organized around a central reference point, creating efficient flow paths in multiple directions simultaneously
2Productivity
If multiple heat transfer plates are used to achieve high heat exchange efficiency, then thermal performance improves, but device complexity and system size increase
Solution Approach 1:
The heat transfer plate design with concentric circular structural elements can be universally applied in various plate heat exchanger configurations, allowing a single plate design to achieve high heat exchange efficiency without requiring multiple specialized plates
Solution Approach 2:
The invention combines multiple flow guidance functions into a single plate design with concentric circular structural elements that simultaneously manage fluid distribution, heat exchange, and flow collection, reducing the need for additional plates
3Productivity
If structural elements are densely arranged to improve heat exchange, then thermal efficiency increases, but flow resistance and fouling risk increase
Solution Approach 1:
The concentric circular arrangement creates smooth curved flow paths that reduce turbulence and dead zones where fouling could accumulate, while maintaining sufficient structural element density for effective heat exchange
Solution Approach 2:
The structural elements are strategically positioned along concentric circles at optimal intervals, providing sufficient heat exchange surface area while maintaining adequate flow channels to prevent fouling, rather than uniform dense distribution

AI summary
The invention relates to a heat exchanger plate for a plate heat exchanger, for the transfer of heat from one working medium to another working medium of the plate heat exchanger, with at least one inlet area (14a; 14b; 14c) and an outlet area (16a; 16b; 16c) for the working medium and/or for the other working medium, and with a plurality of structural elements (18a, 19a; 18b, 19b; 18c, 19c) for guiding the working medium and/or the other working medium from the inlet area (14a; 14b; 14c) to the outlet area (16a; 16b; 16c). It is proposed that the structural elements (18a, 19a; 18b, 19b; 18c, 19c) are arranged along several at least substantially concentric paths (20a, 21a), in particular circular paths, around a reference point (22a; 22b; 22c) located in the inlet area (14a; 14b; 14c) and/or in the outlet area (16a; 16b; 16c).
