Parker Chomerics’ booth at EV & HEV Expo to display thermal gels offering high thermal conductivity for use in high-voltage battery systems

The Chomerics Division of Parker Hannifin Corporation, the global leader in motion and control technologies, today announced that visitors to the Electric & Hybrid Vehicle Technology Expo Europe (Hannover, Germany, 15-17 May 2018) will be able to view displays of the latest thermal management and EMI shielding technologies for automotive electronics at the Parker Hannifin booth #321.

Chomerics will be highlighting the latest THERM-A-GAPTM thermally conductive gels, which provide a high-performance thermal interface between an electric vehicle’s (EV) or hybrid electric vehicle’s (HEV) lithium-ion traction battery modules and the battery enclosure. Chomerics gels also provide a thermal interface for electronics components and modules in active safety systems, power electronics circuits and other automotive systems.

Manufacturers of traction power systems for EVs and HEVs are increasingly adopting thermal gels because of their suitability for use in high-volume and highly automated production environments. Unlike thermal pads and gap fillers – a commonly used thermal interface material – thermal gels may be applied by dispensing equipment, operating as part of an automotive system manufacturer’s automated production line. In addition, a thermal gel conforms readily to the shape of a battery module without imposing mechanical strain on the battery assembly.

The thermal gels which Chomerics will display at the Hannover Expo offer outstanding performance and reliability in automotive applications. The TC50 product, for instance, offers very high thermal conductivity of 5.0 W/m-K and has an operating temperature range of -55 °C to 200 °C. Its heavy paste-like consistency enables controlled dispensing, applied in variable thicknesses to suit the needs of the system.

Chomerics will also be showing its integrated solutions for handling EMI/RFI and protecting against environmental and thermal effects in automotive sub-systems including electronic control units. The Chomerics booth #321 will feature a selection of extrusions for EMI shielding of battery modules.

Visitors to the Parker Hannifin stand will also be able to see Chomerics’ Premier TM PBT-225, an electrically conductive plastic which can be used to form robust and weight-saving gaskets and EMI shields. Premier TM PBT-225 is growing in popularity as a replacement for aluminium or steel gaskets, as it is substantially lighter while offering a good level of attenuation of EMI over a broad frequency range.
