High-Power Thermal Test Emulator (TTE)-Thermal Test Vehicle (TTV)

What is a Thermal Test Emulator (TTE)?

A Thermal Test Emulator (TTE) is a Thermal Test Vehicle (TTV) used to replicate the thermal output of high-performance processors and mainboard components (CPUs, GPUs, and AI Servers, and other semiconductor devices). The Thermal Test Emulator (TTE) extends the capabilities of TTVs by combining multiple TTV modules to simulate the total heat load of an entire server rack or cabinet. It provides engineers with an accurate heat simulation, enabling them to test and validate the efficiency of cooling solutions, such as heatsinks, fans, and liquid cooling systems, before the final hardware is available. TTEs are widely used in R&D labs, server environments, and high-performance computing (HPC) settings to optimize thermal management systems.

This modular thermal test solution ensures comprehensive evaluation of cooling efficiency for modern AI servers, GPU clusters, HPC workloads, data center and CDU .
