Lab Companion Walk-in Rapid Temperature Change Test Chamber — A New Testing Solution for Large-Scale Equipment in the AI Computing Era

In recent years, the iteration speed of core components of AI servers has been accelerating, and the heat load has risen sharply. Taking an AI server equipped with 8 high-end GPUs as an example, its peak power consumption easily exceeds 10kW, and the power density of high-density cabinets soars to more than 50kW or even 100kW, with heat output 3 to 5 times higher than that of traditional servers. More importantly, modern high-load clusters are not the occasional periodic peaks in traditional data centers, but continuous heat generation brought by high-intensity continuous operation. When the hardware operating temperature reaches the critical safety threshold of 85°C to 90°C, the GPU will automatically start the "thermal throttling" self-protection program to cool down by sharply reducing the core frequency, which directly leads to a significant attenuation of computing power, a drop in operating efficiency of up to 25%, and an unlimited passive extension of model training time, seriously restricting the efficiency of AI R&D and application landing.

The drawbacks of traditional environmental reliability testing solutions have been fully exposed in this context. Limited by the cavity volume and heat load capacity, traditional testing equipment cannot accommodate the entire AI server/rack system at all, nor can it simulate the dense heat generated during the actual operation of GPU clusters, failing to meet the full-scenario reliability verification needs of AI equipment. Under this premise, a walk-in rapid temperature change test chamber with high load capacity and accurate environmental simulation capabilities has become an essential key equipment in the R&D and mass production verification links of AI servers, and even a core support for solving the contradiction between computing power and heat dissipation.

Precisely Adapted to AI High-Heat Testing: Lab Companion Walk-in Rapid Temperature Change Environmental Chamber

As a "leader in domestic scenario adaptation" with more than 20 years of experience in the field of environmental reliability testing equipment, Lab Companion, in conjunction with the advanced technical standards of France's Jielong, based on China's strong local R&D and manufacturing capabilities, has launched a high-heat, high-load Walk-in rapid temperature change environmental chamber specifically designed for large-scale high-power equipment testing, which accurately matches the testing needs of the AI computing era.

Large Capacity + High Load, Easily Undertaking AI Whole-Rack Testing

Traditional testing solutions are generally limited by equipment load capacity, making it difficult to restore the real heat generation environment of AI servers under full load, resulting in a disconnect between test results and actual application scenarios. Lab Companion's walk-in environmental chamber has achieved a major technological breakthrough — it can simultaneously carry 1000kg of aluminum ingots and a heat load of up to 50kW for testing, and the load capacity can be flexibly expanded according to the customer's actual testing needs. Whether it is an entire rack of AI servers, GPU cluster cabinets, or high-power communication equipment whole-system, the environmental chamber can easily accommodate them with its "super large capacity", eliminating the need to build additional testing platforms, greatly simplifying the testing process, and improving testing efficiency and accuracy.

Indirect Refrigeration System, Achieving Dual Breakthroughs in Energy Saving and Precision

In terms of energy consumption control and testing accuracy, the environmental chamber is equipped with an advanced indirect refrigeration system, which not only strictly controls the temperature and humidity uniformity within ±2K and the temperature and humidity fluctuation within ±1K during the test to ensure the accuracy and reliability of test data, but also reduces energy consumption by more than 50% compared with traditional refrigeration methods. Long-term use can save customers a lot of energy costs, truly achieving a win-win situation of environmental and economic benefits, and adapting to the needs of enterprises' green development.

Wide Temperature Range and High Precision Control, Adapting to Diversified Industry Standards

The equipment's temperature testing range covers -70℃ to +150℃, and the humidity range covers the standard 20～98%RH (the low-humidity type can be expanded to 5～98%RH), which can meet the diverse testing scenario needs of different AI equipment. The rapid temperature change series supports linear or non-linear temperature change rates from 5℃/min to 25℃/min, and can be equipped with a liquid nitrogen auxiliary refrigeration system to increase the cooling rate to 30℃/min, efficiently simulating extreme temperature change environments. The overall design strictly follows the GB/T 2423.2-2008 high-temperature testing standard, and also meets the latest industry standards such as T/UNP 538-2025, ensuring that the test results are authoritative and universal.

Intelligent Control System, Easy Operation and Full-Process Traceability

The equipment is equipped with the Q8 series intelligent controller, which supports multi-segment program editing, precise temperature and humidity calculation and full-process data recording. It is easy to operate and understand, without cumbersome operations by professional personnel. The entire testing process is traceable, facilitating customers to review test data and optimize test plans. In addition, the environmental chamber can seamlessly conduct joint debugging and testing with new heat dissipation solutions such as liquid cooling, and supports external CDU thermal management equipment, helping whole-machine manufacturers accurately verify the reliability of products under different heat dissipation solutions, quickly find thermal design shortcomings, and then optimize the system thermal management plan to enhance the core competitiveness of products.

Laying a Solid Foundation for Computing Power Breakthroughs, Empowering the High-Quality Development of the AI Industry

Heat is the natural enemy of computing power and a key bottleneck restricting the sustainable development of the AI industry. Lab Companion's high-heat walk-in environmental chamber is precisely the underlying supporting force in the AI computing era — it can not only help enterprises accurately verify the operational stability of AI equipment under extreme heat loads, but also enable the new generation of computing power products to have "temperature resistance for real application scenarios" before they are launched, reducing product failure risks from the source, shortening the R&D cycle, and accelerating product mass production and landing.

Up to now, this series of products has been successfully applied in intelligent computing centers in many countries and regions in the Asia-Pacific. With stable operation performance, accurate testing capabilities and flexible scenario adaptability, it has won wide recognition and high evaluation from industry customers. In the future, with the continuous iteration of AI technology, computing power will be further upgraded, equipment power consumption and heat density will continue to increase, and testing requirements will become more stringent. Lab Companion will continue to deepen its presence in the field of environmental testing equipment, focus on AI computing power testing scenarios, continuously optimize product performance and iterate technical solutions, and contribute domestic strength to the breakthrough development of global AI computing power.
