press release

Fujikura Ltd. (President and CEO: Masahiko Ito) has announced that its cold plates have been adopted as cooling components for the supercomputer "Fugaku," jointly developed by the RIKEN Institute and Fujitsu Limited.

"Fugaku" is the world's top supercomputer, ranking first in the four major unit of "TOP500," "HPCG (High Performance Conjugate Gradient)," "HPL-AI," and "Graph500" in global rankings that compete on the calculation speed of supercomputers.
Supercomputers are large-scale computers whose primary purpose is scientific and technological calculations. With their high computing power, they are expected to make a major contribution to cutting-edge research and development, including improving the accuracy of weather forecasts, earthquake simulations, and predictions of natural disasters such as floods caused by heavy rain, as well as their use in drug discovery and medical treatment for cancer and the new coronavirus, and the creation of new materials and energy.

The high-performance CPUs used in "Fugaku" generate a lot of heat, so our cold plates are used as a space-saving and efficient cooling technology. This cold plate is a high-performance liquid cooling unit that uses a microchannel fin structure (Figure 1). It has strong point / feature of being several times more efficient at cooling compared to air-cooled cooling units while being less than one-third the size (Figure 2). This performance was highly evaluated, leading to its adoption in "Fugaku."

Up until now, we have been involved in many products that use our thermal technology, such as heat pipes, which are internal cooling components for electronic devices such as computers and smartphones. Going forward, we will continue to work on development to further improve the performance of our thermal technology products, including this cold plate, and continue to provide products that meet our customers' expectations.
