Conduction Cooling
Definition
Heat transfer through direct contact between solid materials. Primary mechanism for moving heat from battery cells to cooling system.
Why It Matters
- First step in thermal path for all battery cooling
- Thermal interface materials critical for effectiveness
- Contact pressure and surface finish significantly affect performance
- Most reliable cooling method (no moving parts)
Common Pitfalls
- Inadequate contact pressure between thermal interfaces
- Not accounting for thermal expansion mismatches
- Using materials with poor thermal conductivity in heat path
- Not considering thermal contact resistance in analysis
