Showa Denko Installs Additional Lines to Produce Aluminum Heat Radiators for xEVs TOKYO, Jul 29, 2021 - (JCN Newswire) - Showa Denko K.K. (SDK; TSE:4004) decided to double Oyama Plant's capacity to produce aluminum heat radiators for power modules (PMs)[1] to be installed in electrified vehicles (xEVs) including battery electric vehicles, hybrid vehicles and plug-in hybrid vehicles, in order to respond to an increase in demand for aluminum heat radiators for PMs. SDK has started installation of the additional production line whose start-up of operation is scheduled to be at the beginning of 2022. Aluminum heat radiator for PM PMs are important parts of xEVs and contribute to the improvement in the performance of xEVs. For example, PMs contribute to extension of cruising range and improvement in fuel economy of cars. PMs are usually installed into limited spaces of xEVs. Therefore, heat radiators for PMs must be small, be designed to allow various installation methods, and have high energy efficiency and large heat dissipation capacity.
