Featuring a genuine 50kW full-load thermal testing capacity, our equipment provides robust, reliable thermal validation support for high-power-density AI computing hardware.

1. New Industry Demand: AI Thermal Testing Becomes Mandatory for Reliability

1.1 Skyrocketing Power Density Triggers Exponential Thermal Growth

The booming demand for large-model AI training and inference has driven a comprehensive upgrade of computing hardware power consumption. A single NVIDIA H100 GPU delivers a thermal design power of 700W, while an 8-GPU mainstream AI server achieves a peak power consumption of over 10kW. For high-density computing cabinets, the total heat load can reach 50kW to 100kW, 3 to 5 times higher than traditional general-purpose servers.

Different from the intermittent peak heat generation of conventional data center devices, modern AI computing clusters maintain continuous high-load operation around the clock. Once the core temperature reaches the critical threshold of 85℃–90℃, the GPU activates thermal throttling, significantly reducing core frequency and causing up to 25% computing performance loss. In this context, accurate and stable high-temperature reliability testing has become an indispensable procedure for AI hardware R&D and mass production.

1.2 Three Core Limitations of Traditional Test Equipment

Rapid temperature cycling testing is essential for validating the long-term reliability of AI servers, IP chips, and high-speed optical modules. However, traditional temperature cycling chambers fail to adapt to high-heat, large-size, heavy-weight AI test samples, restricting modern computing reliability verification.

First, self-heating interference causes inaccurate test data. Fully loaded AI servers and GPU modules generate massive continuous heat, disturbing the internal temperature field of traditional chambers. The actual ambient temperature around the DUT deviates greatly from the set value, resulting in poor accuracy and repeatability of test results.

Second, outdated control algorithms lead to temperature overshoot risks. Traditional PID control systems cannot respond dynamically to drastic thermal load changes. Slow heating response and unstable temperature stabilization frequently cause temperature overshoot, exposing high-value engineering samples to abnormal temperature stress and leading to sample damage or invalid test data.

Third, insufficient space and load capacity limit full-system testing. AI testing scenarios have expanded from single chips and boards to complete GPU clusters and 42U server cabinets. Traditional chambers below 1000L lack sufficient internal space and cooling redundancy to support full-cabinet, high-power continuous thermal testing.

Moreover, upgraded global and industrial testing standards further raise industry requirements. GB/T 2423.2-2008 requires server high-temperature testing at 55℃–85℃ for a minimum of 16 hours. The latest T/UNP 538-2025 specification formulates exclusive thermal and environmental adaptability standards for high-power-density servers, making traditional testing equipment completely incompatible with current industry verification demands.

2. Core Performance Specifications of Lab Companion Rapid Temperature Cycling Chambers

2.1 Ultra-wide Temperature Range & Real Full-load Rate Options

Lab Companion TC/TH series rapid temperature cycling chambers support a standard temperature range of -70℃ to +150℃ (max 220℃ temperature difference), with customizable ultra-wide range models from -80℃ to +200℃, covering all extreme high and low-temperature testing scenarios for AI hardware.

The equipment provides five temperature change rate options: 5℃/min, 10℃/min, 15℃/min, 20℃/min and 25℃/min.All rate parameters are tested and verified under full-load conditions, rather than empty-chamber theoretical values. The industry commonly suffers from inflated empty-chamber parameters, where the actual temperature rate drops sharply after loading samples. Lab Companion adheres to authentic full-load data calibration, ensuring consistent and reliable real-world performance for global customers.

2.2 Large Space & High Load Capacity for Full-cabinet Testing

To meet full-system testing demands for AI server cabinets, Lab Companion CW series walk-in rapid temperature cycling chambers offer flexible capacities from 1000L to 10000L, with fully customizable cabin dimensions to fit different laboratory environments.

The series delivers industry-leading load performance, supporting 1000kg mechanical load and 50kW continuous thermal load testing with expandable heat load capacity. With only 10m³ of test space, the chamber stably sustains 50kW+ high-heat-load operation, directly accommodating complete AI server cabinets, GPU clusters and high-power communication equipment without additional auxiliary test platforms.

2.3 High-precision Temperature Control with Ultra-low Overshoot

Lab Companion TC series achieves outstanding temperature stability, with temperature fluctuation ≤±0.3℃ and temperature deviation ≤±2℃. Even at a high cycling rate of 15℃/min, the temperature overshoot is strictly controlled within ±0.5℃.

This precise control performance is critical for thousand-cycle temperature reliability tests of server motherboards. It effectively avoids excessive thermal stress on BGA solder joints and PCB structures, preventing sample failure and ensuring the accuracy and consistency of long-term reliability test results.

3. Core Technologies Enabling Stable 50kW High-heat-load Testing

3.1 Enhanced Cooling System with Sufficient Power Redundancy

Traditional chambers are designed based on low-heat or zero-heat sample assumptions, resulting in insufficient cooling capacity under 10kW+ thermal loads and drastic temperature rate attenuation. Lab Companion upgrades the overall cooling architecture for high-power computing testing scenarios. The compressor power is more than twice that of conventional chambers with the same volume, providing sufficient cooling redundancy to offset continuous high heat generation from AI devices and maintain stable temperature cycling performance.

3.2 Advanced Indirect Refrigeration System: High Precision & Energy Saving

Equipped with a high-efficiency indirect refrigeration system, Lab Companion walk-in chambers optimize heat exchange and energy control logic. The system controls temperature and humidity uniformity within ±2K and fluctuation within ±1K, exceeding mainstream industry precision standards. Meanwhile, it reduces overall energy consumption by over 50% compared with traditional cooling solutions, significantly lowering long-term operational and R&D testing costs.

3.3 Optimized Air Duct Design Ensures Uniform Large-space Temperature Field

For large-volume walk-in test cabins, conventional fan solutions struggle to achieve uniform temperature distribution. Lab Companion adopts a high-volume forced convection system, combined with multi-point PID synchronous adjustment and zoned temperature compensation technology. This design eliminates local temperature differences in large cabins and ensures consistent test conditions and accurate data for full-cabinet AI hardware testing.
