At Electric & Hybrid Europe, Parker Chomerics is showcasing its latest thermal management materials for battery cooling including a range of thermal gels. The company will also be exhibiting its wider integrated solutions for the automotive industry on stand 404. The growing popularity of electric and electric hybrid vehicles has added further complexity to the tasks facing automotive electronic design engineers.

Efficient battery management is crucial to the development of next-gen cars and Chomerics is at the edge of thermal management technology for these applications including thermally conductive gels, gap fillers, insulators and phase change materials.

Chomerics is placing particular focus on its thermal gels which are suited to automated high speed dispensing. The THERM-A-GAP gels are supplied as pre-cured compounds that can be dispensed over heat generating components. They result in much lower mechanical stress than other materials and provide a flexible solution in circumstances where there are variable size gaps.

Thermal filler pads will also be showcased. These have a cross-linked gel structure that provides long-term thermal stability. In addition to battery thermal management, Chomerics will be showing its integrated solutions to handle EMI/RFI and protect against environmental and thermal effects in automotive sub-systems including ECUs. There is also a selection of extrusions for EMI shielding which could be used to shield the electric traction elements.

The level of electronics content within cars generally continues to rise driven by safety, infotainment and Advanced Driver Assistance Systems (ADAS). This brings with it a corresponding rise in the EMI/RFI shielding and thermal management challenges. These must be addressed to ensure that electronics systems and modules work reliably in the harsh electrical environment that is typical of in-vehicle applications.

Chomerics’ Premier PBT-225 electrically conductive plastic will also be on display. This facilitates a move from metal to plastic housing conversions, reducing the weight of enclosures and the costs associated with secondary operations such as assembly and machining.
