Thermal Management (Gap Filler)
Thermal management safely dissipates excessive heat away from a part, so that it functions properly and does not combust. In electric vehicles, this usually involves surrounding or encapsulating battery packs or modules in gap filler.
Handling Highly Abrasive Thermal Interface Material
Thermal interface materials used in gap filling applications are critical to overall battery performance and safety. When dispensed correctly, the gap fillers dissipate heat away from the battery, improving battery speed, longevity and decreasing the likelihood of thermal events.
However, pumping and dispensing thermal interface material (TIM) brings many challenges to electric vehicle (EV) battery assembly lines. Highly abrasive and low viscosity in nature, the gap filler can quickly wear out equipment. TIM also needs unique attention to pressurization to ensure optimal heat transfer.
To withstand this tough material, manufacturers should consider robust equipment that allows for high flow, precise metering and dispense.
Choose Elite construction for applications of highly abrasive thermal interface materials (TIMs), silicones, urethanes, and epoxies. When your system configuration includes pumps and valves with Elite construction, you can expect to…
- dispense at least 50,000 gallons (200,000 liters) before noticing any wear on pump pistons and cylinders*
- get at least 10 times more equipment life, compared to standard systems*
How do we know? Read the research.
* Results may vary. Variables affecting component life include, but are not limited to, material chemistry/fillers, flow rate, cycle rate, maintenance diligence, and system pressure.
