Suzhou, China — Trumony Aluminum Limited, a specialist in aluminum thermal management components, has introduced its new aluminum liquid cooling plate engineered for electric vehicle (EV) battery packs, energy storage systems (ESS) and high-density power electronics. The launch expands the company's cold plate portfolio and gives battery integrators a compact, high-efficiency way to control heat where air cooling is no longer enough.
As battery energy density rises, thermal management has become the decisive factor in pack safety, longevity and charging speed. Air-cooled designs struggle to remove heat uniformly, allowing hot spots that accelerate cell degradation and raise the risk of thermal runaway. The new liquid cooling plate addresses this by routing coolant through precision-brazed channels directly beneath the cells, holding cell-to-cell temperature differences within a narrow band while keeping pressure drop low.
"Liquid cooling is no longer a premium feature reserved for high-end vehicles," said a Trumony spokesperson. "It is becoming the baseline for reliable battery systems. Our goal is to make an efficient, fully customizable liquid cooling plate accessible to every integrator, from fast-growing EV startups to utility-scale storage manufacturers."
Built for Demanding Thermal Loads
The plate is manufactured from 3003, 3005 and 6061 aluminum alloys using vacuum brazing or roll bonding, producing leak-tight channels with excellent thermal conductivity and corrosion resistance. Each unit is 100% leak tested and dimensionally inspected before shipment, so downstream assemblers can integrate with minimal rework.
- High heat transfer efficiency: optimized channel geometry maximizes coolant contact area for faster heat removal.
- Uniform temperature control: balanced flow distribution protects battery life and performance.
- Lightweight aluminum construction: reduces pack weight without compromising strength.
- Leak-tight joining: vacuum brazing and roll bonding deliver reliable, durable seals.
- Fully customizable: size, thickness, port position and connector types tailored per project.
