Chubu Electric Power Co., Inc. (President & Director: Satoru Katsuno; Location: Nagoya City, Aichi Prefecture), Yutaka Electronics Industry Company Ltd. (President & CEO; Takafumi Morita; Location: Kariya City, Aichi Prefecture; hereinafter "Yutaka Electronics Industry") and NAOMOTO Corporation (Representative Director and CEO: Yukio Naomoto; Location: Osaka City, Osaka Prefecture; hereinafter "NAOMOTO") jointly developed a "rapid cooling apparatus" (product name: HD Blast Cooler) that can cool metal products in less than 1/100 of time compared to the conventional natural heat radiating method and fan cooling method.
The problem with the cooling methods that used natural heat radiation or fan, which were mainstream in the process of cooling metal products at the factory, was that cooling time was long. There was also a method of shortening cooling time by immersing metal in water, but the problem with this was that it caused defects in products due to cracking and that drying was necessary after cooling. Thus, a cooling method that shortened cooling time and resolved defects in products was desired.
By applying micro droplets (mist) and high-pressure air to products, the developed apparatus cools products without causing defects in less than 1/100 of time compared to the conventional natural heat radiating method and fan cooling method. Products weak against water can be cooled with high-speed cold air from the installed fan.
The developed apparatus will be released in January 2018 from Yutaka Electronics Industry and NAOMOTO, aiming for annual sales volume of 50 units.
The developed apparatus will be exhibited at "Techno Fair 2017" to be held on October 26 and 27 by the Technological Development Division of Chubu Electric Power (20-1 Kitasekiyama, Odaka-cho, Midori Ward, Nagoya City).
