Enter Conditions
Enter your actual or estimated design conditions. The tool estimates the heat source temperature using product thermal impedance data.
Heat Source
Heat generated by the component under design operating conditions
Temperature limit the source contact surface must not exceed
Cooling & Assembly
Estimated temperature at the TIM–heat sink interface
Select the pressure closest to your actual assembly conditions
Effective Contact Area
Default: 25.4 × 25.4 mm. Adjust to the actual contact size.
Calculation Method & Assumptions
| Symbol | Meaning |
|---|---|
| Q | Heat source power (W) |
| k | TIM thermal conductivity (W/m·K) |
| L | TIM thickness (m) |
| A | Effective contact area (length × width, converted to in²) |
| Rt | TIM thermal impedance (°C·in²/W) |
| Th | Estimated source temperature (°C) |
| Tc | Heat sink contact surface temperature (°C) |

Notes
Before Use
- Values are typical catalog thermal impedance data. Actual performance varies with surface flatness, pressure uniformity, assembly method, long-term aging, and other factors.
- Results support preliminary screening only and do not replace sample testing or system validation. Please test samples before mass production, or consult our Sales or Technical Support team.
- LiPOLY assumes no liability for final design decisions made based on the results of this tool.
Interpreting Results
- Results use the typical thermal impedance data listed in the product catalog. The unit is °C·in²/W.
- If the selected pressure has no data, the nearest available pressure is used and marked with a grey label.
- Items without product pages show “Coming Soon” Contact Sales or Technical Support for details.
