Solution Overview
Problem
Existing methods for producing microstructures on heat transfer surfaces are limited in their ability to enhance both heat and mass transport, as well as chemical reactivity, particularly in systems with curved surfaces, and do not effectively utilize concave and convex areas for heat transfer and catalytic reactions.
Innovation Solution
A method involving electroplating and mechanical spray compacting processes to create microstructures on components with curved surfaces, using a radiation-sensitive photoresist that adapts to the surface shape, forming continuous microstructures on both convex and concave areas, and incorporating microfine pores through ion beam technology and deep etching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electroplating methods are used on flat surfaces, then microstructures can be produced, but they cannot effectively cover curved surfaces with concave and convex areas
Solution Approach 1:
The patent applies a radiation-sensitive photoresist that can adapt to curved surfaces, allowing the formation of microstructures on components with concave and convex areas. The photoresist is applied in a plasticized state, enabling it to conform to the surface curvature, and then hardened to maintain the adapted shape, achieving uniform microstructure coverage on non-planar surfaces.
Solution Approach 2:
The patent changes the physical state of the photoresist from plasticized (flexible) to hardened (rigid) through radiation exposure. This parameter change allows the photoresist to first adapt to the curved surface geometry and then maintain that adaptation during subsequent processing steps, enabling precise microstructure formation on complex geometries.
2Productivity
If microstructures are produced only on convex surfaces, then production is simpler, but heat transfer and mass transport efficiency is reduced
Solution Approach 1:
The patent creates a universal method for producing microstructures that works on all surface types (convex, concave, and curved). The photoresist application process and electroplating method are designed to be universally applicable to any component geometry, enabling microstructure formation throughout the entire heat transfer surface area, thereby maximizing heat transfer and mass transport efficiency.
3Productivity
If ion beam technology and deep etching are used to create microfine pores, then heat transfer performance increases, but manufacturing complexity increases
Solution Approach 1:
The patent applies the photoresist in a plasticized state before electroplating, allowing it to adapt to the surface geometry in advance. This preliminary adaptation simplifies subsequent processing steps, as the photoresist is already positioned correctly to receive the metal layer and guide the formation of microfine pores through ion beam technology and deep etching, reducing overall manufacturing complexity.
