Our company offers a revolutionary heat transfer fin that can be retrofitted onto piping. The "Standard Fin" is a standardized fin that achieves rapid supply and no initial costs from "design consideration" to "optimal selection." It can solve thermal challenges with thin plate fins. There are examples where using this product resulted in a 40% increase in heat dissipation, and cases where simply wrapping one fin around the piping led to a 20% increase in temperature reduction with natural air cooling and a 36% increase with forced air cooling. For more details, please refer to the PDF download. 【Thermal Fluid Analysis Examples】 - Evaluation of the performance obtained when multiple fins are attached to the piping. - Evaluation of the effect on the piping surface when multiple fins are attached. - Evaluation of the performance obtained when fins are attached to a hexagonal pipe carrying low-temperature fluid. - Evaluation of the performance obtained when a fin is attached to a cooling hole. *For more details, please refer to the PDF materials or feel free to contact us.

The "Wave Fin" is a heat transfer fin with a wavy shape in the fin section. Our products are manufactured using unique equipment that leverages the characteristics of press processing, resulting in minimal variation in fin height, which can improve production efficiency in subsequent processes (such as joining and assembly) and stabilize performance. This time, we have developed a high-performance fine wave fin in one shape as a standard product. It can be used in various applications, such as cooling Peltier elements, attaching to curved surfaces of motors, and wrapping around pipes. 【Features】 ■ High Performance - Enables heat exchange in a compact range ■ Flexible - The fin's pitch has been adjusted, making it easier to wrap around curved surfaces ■ Low Cost - Customization options for different fin heights and pitches can be accommodated with processing of only the mold parts *For more details, please feel free to contact us.

• Heat exchanger

Recommended for those who want to create several heat exchangers using wavy fins. ■ Plate Type A heat exchanger with a structure made by laminating several types of plate materials and our wavy fins. By innovating the hole shapes, plate thickness, and fin dimensions of the plate materials, it is possible to design heat exchangers with various flow path structures. It is recommended for liquid-liquid heat exchangers when the fin height is low. ■ Radiator Type A heat exchanger with a radiator structure composed of tubes, headers made from two sheets of metal, and two types of fins. By making the header part a laminated structure, it easily accommodates changes in fin height and the number of tubes. It is recommended for situations where one side is connected to existing piping and cooled with a fan, etc. Currently, design drawing data is available for download. 【Features】 ■ The variation in fin height is small due to press processing, and the flatness of the top and bottom surfaces is high. ■ By changing the curvature and pitch of the wave shape, it supports small lot production. ■ Customization is possible for shape, material, plate thickness, and manufacturing method. *For more details, please refer to the materials available via the download button. ★ Free samples are currently being offered.

The essential heat transfer fins for compact and high-performance heat exchangers come in various shapes, such as corrugated, wave, and offset shapes. Each shape requires a mold, making them not easily accessible. To cater to such customers, we have cataloged the waving fins. ■ Wave R1.6 The fin heights are available in three types: 2mm, 3mm, and 4mm. The Wave R has a small wave and a small wave pitch, resulting in a shape that causes intense and turbulent flow. Among the three types, it has the highest heat transfer performance, but it also has significant pressure loss, requiring fins or pumps with high static pressure. ■ Wave R2.8 The fin heights are available in five types ranging from 2mm to 6mm. Its performance and pressure loss are intermediate among the three types. The fluid flows along the moderate waves, making it less likely for debris to clog. ■ Wave R20 The fin heights are available in nine types ranging from 2mm to 10mm. Although it has the lowest performance among the three types, it also has low pressure loss, making it a user-friendly shape. With a wide variety of height options, it can be used in various specifications of heat exchangers. Currently, we are offering free samples. You can freely select the number of fins to match your heat exchanger and check the estimated quote online.

The "Waving Fin" is a heat transfer fin made from thin sheet metal through press processing. It standardizes the fin height in 1mm increments based on three types of wave shapes, allowing for purchases of one unit tailored to specific needs without the need for mold investment. You can also choose the number of fins, and we can accommodate dimensions other than standard products. Like typical corrugated fins, it can be used as a thin plate fin in heat exchangers, contributing to improved performance while keeping costs down. 【Features】 ■ The press processing results in minimal variation in fin height and high flatness on both the top and bottom surfaces. ■ By changing the curvature and pitch of the wave shape, it supports small lot production. ■ Customization is available for shape, material, thickness, and manufacturing method. *For more details, please refer to the materials available via the download button. ★ Free samples are currently being offered. If you are interested, please apply through the inquiry form.

• Heat exchanger

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."

Additionally, for dimensions and shapes other than standard products, we can create dedicated molds as a customization project to accommodate your needs. We also possess methods for low production quantities, mass production techniques, and large fins with a maximum flow path length of 600mm, so please feel free to consult us. 【Features】 ■ High-precision thin sheet metal heat transfer fins for small lot heat exchangers ■ Fin heights available in 1mm increments, as frequently requested ■ Can be used for catalyst support materials, leveraging surface area ■ Customization available: corrugated and offset shapes ■ Customization available: aluminum, copper, titanium, Inconel, etc. ■ Customization available: maximum flow path length of 600mm, maximum fin height of 50mm *For more details, please refer to the PDF document or feel free to contact us.

The "Slit Folding Fin (FFSL)" is a fin shape that has been improved from our original folding fin shape (hereinafter referred to as FF). By incorporating slits into the fin part of the "FF," flexibility is achieved in directions that could not be bent with the FF, allowing the fins to be wrapped not only parallel to the piping but also vertically. Depending on the orientation of the piping and the attachment location, changing the installation direction allows for aligning the fin orientation to a suitable direction even in retrofitting, enabling high performance. 【Features】 ■ Flexible ■ Lightweight ■ High performance *For more details, please refer to the PDF materials or feel free to contact us.
