Thermal simulation of heat sinks

We build a Conjugate Heat Transfer (CHT) thermal model of your heat sink design. Air and solid regions are modeled separately in our multi-region CHT approach, where heat transfer is calculated based on energy balance between air and solid regions. Heat convection and heat conduction can be simulated using our thermal model:

• An accurate thermal model is developed according to your application.
• CFD simulations are performed for various thermal conditions.
• Thermal resistance, Nusselt number and pressure drop of the heat sink are determined acording to the CFD results.
• Simulation results are post-processed and reported.

Benefits of thermal simulations

• Virtual Prototyping: Thermal simulations allow engineers to test and refine heat sink designs virtually before physical prototypes are built. This reduces development costs and time-to-market for IT devices.
• Performance Optimization: Simulations can predict the thermal performance of different heat sink designs under various operating conditions. This allows for optimization of fin design, material selection, and overall heat dissipation capabilities.
• Identifying Hotspots: Simulations can identify potential hotspots on the heat sink and surrounding components. This allows for targeted improvements in cooling strategies or component placement to prevent overheating.

Analyzing simulation results

• Temperature Distributions: Simulations provide visual representations (e.g., color maps) of temperature distribution across the heat sink and IT device components.
• Heat Flux Analysis: Heat flux values (rate of heat transfer) across different surfaces can be analyzed to identify areas requiring improved heat dissipation.
• Performance Metrics: Simulations can predict key performance metrics such as maximum operating temperature and thermal resistance of the heat sink.
