We would like to introduce the "Lotus Fin" handled by Towa Electric Co., Ltd. Lotus metal is a porous copper material created using a special casting method. The countless pores that penetrate from top to bottom dramatically increase the surface area and achieve excellent heat dissipation. Using this Lotus metal, we conducted comparative experiments on the cooling performance against commercially available high-spec PC CPU coolers. Despite a 76% reduction in volume ratio, it demonstrated 1.1 times the cooling performance. This translates to approximately four times the cooling performance at the same volume ratio. 【Features】 - Achieves thermal conductivity equivalent to silver sintering through unpressurized, low-temperature bonding. - With high heat dissipation performance, it enables miniaturization, high performance, and energy savings. - The pores are aligned in one direction, resulting in excellent thermal conductivity and fluid permeability. *For more details, please download the PDF or feel free to contact us.

"Galden" is a fluorinated insulating fluid suitable for immersion cooling systems. It has excellent electrical insulation properties and high chemical stability, making it widely useful for cooling semiconductor manufacturing equipment and electronic products, as well as for cleaning pumps and equipment due to its ease of handling. Additionally, it shows high compatibility with all metals, various rubbers, commercially available elastomers, and plastics. 【Features】 ■ Wide boiling point range from 55 to 270°C ■ Maintains high heat resistance ■ Decomposition temperature above 290°C ■ Particularly high boiling point grades have low evaporation loss ■ Ozone depletion potential is zero (zero ODP) *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "POC System" handled by Towa Electric Co., Ltd. This product is a two-phase liquid immersion cooling device that immerses the entire motherboard, which has high heat-generating components such as CPUs and GPUs, in a refrigerant. It can be used as an experimental device for immersing various materials around the substrate, such as electronic components, conductive parts, and insulating materials, in boiling refrigerant for an extended period. 【Features】 ■ Easy to conduct evaluation tests in a two-phase liquid immersion cooling environment ■ Desktop size *For more details, please refer to the related links or feel free to contact us.

The "Sora Sola Mini" is a desktop immersion cooling system designed to cool high-load devices that heavily utilize GPUs, such as supercomputers, mining, AI, and e-sports deep learning. It features a round transparent acrylic tank with excellent aesthetics that allows you to see the boiling process, making it suitable for gaming use. Additionally, the special refrigerant enables boiling latent heat cooling compared to oil immersion, and it offers good maintenance for the boards. 【Features】 ■ Designed to accommodate one built-in ATX board ■ Built-in GPU board ■ Equipped with dry-run prevention function ■ Compact high-performance bellows included ■ The dedicated radiator can cool one desktop immersion unit per unit ■ One MHI dry cooler can cool five desktop immersion units *For more details, please refer to the related links or feel free to contact us.

The "liquid immersion cooling system" is a system that immerses ICT equipment such as servers in a special insulating liquid to directly cool the servers. Because the refrigerant comes into direct contact with the equipment for cooling, it is gaining attention as a highly energy-efficient cooling method compared to traditional air cooling. Additionally, the refrigerants used in liquid immersion cooling include fluorinated inert liquids and silicone oils. 【Features】 ■ Better cooling efficiency compared to traditional air and water cooling ■ Space-saving ■ Reduces noise during cooling *For more details, please refer to the related links or feel free to contact us.
