Thermal analysis plays a critical role across industries such as manufacturing, engineering, and materials science. It involves evaluating how materials behave under varying temperature conditions to understand their thermal properties and performance in real-world environments. This insight is essential for optimizing designs, ensuring product reliability, and meeting safety and regulatory requirements.

Our thermal analysis services provide comprehensive insight into material behavior, enabling customers to optimize manufacturing processes, enhance product performance, and ensure compliance with relevant industry standards. These analyses also help identify and mitigate potential risks, including thermal degradation, phase transitions, and material incompatibility.

Renxin.Thermal offers advanced thermal analysis and validation services using powerful Computational Fluid Dynamics (CFD) tools and proprietary simulation platforms. Our in-house thermal engineers support the entire development cycle—from component level to board and full system level analysis. By directly importing CAD data into our simulation environment, we deliver fast and accurate thermal evaluations within short lead times

Our CFD-based thermal analysis leverages state-of-the-art modeling techniques in fluid dynamics and finite element analysis. This enables rapid optimization of heatsink designs to meet specific performance targets—often within 24 hours.

The simulation platform can:

• Predict thermal performance under varying airflow conditions
• Optimize fin configurations, including density, thickness, and layout
• Identify the best fin structure to balance heat dissipation and pressure drop
• Evaluate multiple design scenarios efficiently

In addition, our system integrates manufacturing process knowledge—including die casting, micro forging, extrusion, investment casting, and CNC machining—allowing us to recommend the most cost-effective solution based on both thermal performance and production feasibility.

Through iterative simulation, we can quickly converge on an optimized heatsink design, significantly reducing development time and cost. Once the design is validated, rapid prototyping technologies are used to produce functional samples within days.

This approach enables:

• Faster design validation in real application environments
• Reduced need for multiple prototype iterations
• Shortened time-to-market

Electronic assemblies must effectively dissipate heat to prevent overheating and premature failure. Renxin.Thermal specializes in designing custom thermal solutions to address complex heat dissipation challenges.

In a project with a world-leading lithography equipment manufacturer, a critical module within the system experienced overheating issues. Using ANSYS Icepak and theoretical data analysis, our engineering team conducted detailed thermal simulations and identified two key root causes:

1. The fluid channel diameter was undersized, resulting in a low heat transfer coefficient
2. The fluid path design was overly complex, leading to excessive pressure drop

To address these challenges, the design was optimized as follows:

• Increased the fluid channel diameter from 10 mm to 12 mm
• Redesigned and simplified the coolant flow path
• Optimized the layout considering the impact of mounting holes on the flow channels

Following redesign and validation, prototype testing was completed within 5 days. The final solution was delivered to ASML for system-level integration testing.
