Thermal Test Vehicle (TTV) Product

Thermal Test Vehicles (TTV) & Thermal Test Emulators (TTE) — Advanced Cooling Validation for AI & HPC

As AI processors continue pushing power density boundaries, thermal validation has become a critical part of cooling system development. KLC offers a complete line of Thermal Test Vehicles (TTVs) and Thermal Test Emulators (TTEs) designed for chip-level, board-level, and system-level thermal validation.

Driven by next-generation AI servers, HPC platforms, GPU accelerators, and automotive ADAS processors, engineers must validate cold plates, liquid cooling systems, CDUs, and advanced thermal architectures before production silicon becomes available.
