Aspect ratio 20 times. Standardization of tall corrugated fins. Presentation of materials introducing examples of problem-solving.
The "Corrugated Fin" is a heat transfer fin made by bending thin sheet metal using our unique equipment. Generally, as the aspect ratio (fin height ÷ fin pitch) increases, the fin thickness becomes thicker and the gaps become smaller. However, by bending thin sheet metal, sufficient gaps can be secured even with an aspect ratio of 20 or more. Moreover, even with a large aspect ratio, the gaps are maintained, making it significantly lighter compared to typical heat sinks of the same size. The maximum fin height is 75mm and the flow path length is 100mm, but we can also accommodate requests for custom dimensions. 【Features】 ■ Lightweight while maintaining size and surface area ■ Three sizes available in the lineup (as of September 2021) ■ For users of our folding fins, both sides of the fin contribute to the heat exchange area, allowing for an increase in surface area while remaining lightweight. *You can view materials introducing examples of problem-solving from the "PDF Download."

basic information
Generally, for press processing, the fin height is around 25mm. Heights beyond that often require special methods or are produced through sheet metal processing (one bend at a time), both of which have challenges such as high investment costs or low productivity. At our company, we have developed our own manufacturing equipment, allowing us to produce corrugated fins with a height of up to 75mm using minimal parts. If you are looking for new tall heat transfer fins or cannot find a processing partner for sheet metal corrugated fins, please feel free to consult us. 【Specifications】 Material: Aluminum A1050 Plate thickness: 0.2/0.3mm Fin pitch: 2.0/2.5/3.0mm Fin height: 40/60/75mm Fin width: 100mm Fin length: 62/77.5/93mm ★ We are also developing thin plate high aspect ratio offset fins, twist fins, wrapping fins, and more! Please feel free to contact us for more details.
