Battery Cold-Plate Flow Distribution

A thermal-fluid concept comparing manifold layouts for a liquid-cooled battery-module cold plate.

Project brief

This concept would compare cold-plate channel and manifold layouts for a generic battery module using imposed heat loads. The study would make heat-source assumptions, coolant properties, and contact resistance explicit so that geometry effects can be discussed without implying a validated pack design. Candidate layouts would be evaluated for temperature uniformity, pressure-drop tendency, and practical machining or joining constraints. CAD sections would explain the flow path and the interfaces to a representative module. A later bench experiment would use electrical heaters and instrumented coolant rather than live cells for initial characterization. The proposed deliverables are a geometry trade study, model setup notes, and a correlation plan. No cell life, fast-charge capability, or thermal performance result is claimed.

Design concept developed for this portfolio. The diagrams describe the proposed system; implementation and testing are part of the validation plan.

The engineering challenge

Distribute coolant and remove nonuniform heat without making the plate excessively restrictive or difficult to manufacture.

Engineering approach

  1. Define imposed heater loads and coolant assumptions.
  2. Compare parallel and serpentine channel families.
  3. Review manifold balance and contact-resistance sensitivity.
  4. Plan a heater-based thermal correlation experiment.

Validation plan

  • Check mesh sensitivity and energy balance in the model.
  • Measure inlet, outlet, and plate temperatures on a heater rig.
  • Compare measured pressure drop with the modeled trend.

Concept scope

  • Parameterized flow channels
  • Manifold comparison
  • Contact-resistance sensitivity
  • Machining-aware geometry
  • Heater-based test concept
