Advanced Thermal Testing Facility
Heatscape’s Advanced Thermal Testing Facility is where empirical design validation and simulation meet real-world performance. While Computational Fluid Dynamics (CFD) software offers essential preliminary insight, hardware validation in an optimized lab setting is critical to guarantee physical performance.
Our facility utilizes precision wind tunnels, closed-loop liquid testing rigs, multi-channel data loggers, and automated thermal sensors to accurately measure thermal resistance, pressure drop (dP), volumetric airflow (CFM), and fluid dynamics under exact environmental conditions.
When to Use It
Relying solely on simulations can introduce structural blind spots like interface resistance deviations, localized hot spots, or bypass airflow anomalies. You should utilize our testing facility when:
- Validating Critical Prototypes: Correlating physical test data against initial CFD models to eliminate design variances.
- Testing High-Power Densities: Verifying thermal dissipation for high-performance ASICs, CPUs, or 1000W+ GPUs where minor thermal failures lead to catastrophic system downtime.
- Optimizing Airflow and Pressure Drops: Ensuring complex fin geometries do not cause severe pressure drops that strain system fans.
- Validating Compliance and Reliability: Ensuring compliance with rugged environmental standards across telecommunications, medical equipment, and data center environments.
💡 Engineering Tip: For highly complex or unreleased chips, combine our testing facility with custom Thermal Test Vehicles (TTVs). Our TTVs accurately simulate specialized heat fluxes up to 1000W+ with local hot spots, preserving expensive live silicon during early validation phases.
Required Design Inputs
To accelerate setup and achieve the highest level of testing precision, we request the following technical inputs:
- CAD Models & Mechanical Layouts: .STEP, .IGS, or SolidWorks files detailing the system enclosure, component placement, and board geography.
- Thermal Performance Target: Maximum allowable junction temperature ($T_j$), target thermal resistance ($R_{th}$), and expected power dissipation (Watts).
- Boundary Conditions: Airflow parameters (available linear feet per minute – LFM, volumetric flow rate), ambient operating temperatures ($T_{amb}$), and liquid loop parameters (coolant type, flow rate in GPM, inlet temperatures) if liquid cooling is used.
- TIM Specifications: Details regarding your preferred Thermal Interface Material (thickness, conductivity, and clamping pressure requirements).
The Testing Process
- Fixture Engineering & Setup: We design customized mounting plates or test enclosures to isolate bypass airflow and replicate your system’s exact physical orientation.
- Sensor & Probe Calibration: Thermocouples (Type T or K) are embedded into critical junction points, and RTD sensors or thermal imaging cameras are aligned.
- Data Acquisition Running: The assembly is subjected to controlled thermal loads. We systematically track temperature deltas ($\Delta T$), pressure drop curve characteristics, and flow velocity metrics.
- Data Correlation & Analysis: Test results are rigorously compared against initial design criteria and CFD models to confirm structural accuracy.
- Comprehensive Reporting: You receive detailed thermal resistance curves, aerodynamic pressure drop data, and actionable engineering recommendations.
Applications
Our testing services are tailored across a wide variety of specialized architectures and custom cooling solutions:
- AI & High-Performance Computing (HPC): Testing micro-skived cold plates and vapor chamber integrations engineered for high-density server racks.
- Telecommunications & 5G Infrastructure: Evaluating ruggedized, sealed enclosures under natural or forced convection, mimicking harsh outdoor conditions.
- Custom Heatsink Optimization: Empirical testing of performance differences across various manufacturing technologies—ranging from low-cost Extruded Heatsinks with embedded heat pipes to highly intricate Skived & Microskiving Heatsinks for high heat densities.
