Guangzhou Chuangrui Automotive Electrical Appliance Co., Ltd. and Aipei Technology have reached a strategic cooperation: a 900 liter rapid temperature change test chamber helps upgrade the reliability of automotive electronics

——Breakthrough the industry testing bottleneck with a linear temperature change rate of 15 ℃/min

1、 Project background: High standard challenges in the new energy vehicle industry

Guangzhou Chuangrui Automotive Electrical Appliance Co., Ltd. (hereinafter referred to as "Chuangrui Automotive") is a core supplier of electronic components for new energy vehicles. Its products include key components such as on-board chargers, high-voltage distribution boxes, and battery management systems (BMS). With the increasingly stringent requirements for environmental adaptability in the new energy vehicle industry, Chuangrui Automotive needs to verify product reliability through more efficient testing methods to address the following challenges:

Rapid temperature change scenario: such as a vehicle quickly entering a low-temperature tunnel (-20 ℃) from a high-temperature exposure environment (60 ℃+), or rapidly accelerating to heat up after starting at low temperatures in high-altitude areas;

Testing efficiency bottleneck: The traditional testing chamber has a temperature change rate of only 8-10 ℃/min and a single testing cycle of 6-8 hours, which affects the speed of R&D iteration;

International certification requirements: Products need to pass international standards such as ISO 16750 and IEC 60068, with higher requirements for indicators such as temperature change rate and uniformity.

In January 2024, Chuangrui Automotive submitted an urgent request to Aipei Technology: to purchase a 900 liter high-capacity rapid temperature change test box, which is required to achieve a linear temperature rise and fall rate of 15 ℃/min, and have high uniformity, low noise, and long-term stability to support the research and development verification of its new generation of high-voltage platform products.

2、 Aipei Technology Solution: Technological Breakthrough and Customized Delivery

As a specialized and innovative "little giant" enterprise in the field of environmental testing equipment, Aipei Technology provides the following core solutions for the needs of Chuangrui vehicles:

1. Ultra high speed temperature change technology: 15 ℃/min linear control

Parallel connection of dual refrigeration system: using two sets of German Bitzer semi closed compressors, the refrigeration capacity is increased by 30%, achieving ultra wide temperature range coverage from -70 ℃ to 180 ℃;

Dynamic heating compensation: Equipped with imported heating tubes and intelligent PID algorithm, the heating rate also reaches 15 ℃/min, and the temperature fluctuation is ≤± 0.3 ℃;

Optimization design of air duct: Through CFD simulation, optimize the structure of the circulating air duct to ensure the uniformity of the temperature field in a 900 liter large space of ≤± 1.5 ℃ (industry average ± 2 ℃).

2. Intelligent and Reliable Design

AP-SSMART 4.0 control system: supports 200 segment program programming, real-time curve display, and remote monitoring, and can simulate complex temperature change curves (such as step heating and transient impact);

Safety protection mechanism: equipped with over temperature protection, compressor overload alarm, and power-off memory function to ensure stable operation of the equipment 24/7;

Energy saving and noise reduction: Adopting a variable frequency compressor and soundproof cotton design, the operating noise is ≤ 60dB, and the energy consumption is reduced by 15% compared to traditional equipment.

3、 Project Execution: Efficient Delivery and Rigorous Acceptance

Quick response and customized production

The Aipei Technology technical team completed the scheme confirmation within 72 hours and initiated the production process, shortening the delivery cycle to 45 days (industry average of 60 days) through modular design;

In response to the space limitations of the Chuangrui Automotive Laboratory, customized equipment sizes and mobile wheel designs are available for flexible deployment.

On site installation and training

In March 2024, the equipment arrived at the Guangzhou R&D center of Chuangrui Automotive. The Aipei Technology engineering team completed installation and debugging, and conducted operation training to ensure that the testing personnel mastered the key points of equipment use and maintenance.

Acceptance test results

Temperature change rate: No load 15.2 ℃/min, full load (500kg load) 14.8 ℃/min, as required by the contract;

Uniformity of temperature field: measured ± 1.3 ℃, better than the contractually agreed ± 1.5 ℃;

Stability test: Continuous operation for 72 hours, temperature fluctuation ≤ ± 0.5 ℃.

The director of the Chuangrui Automotive Laboratory commented, "Aipei Technology's equipment not only meets technical specifications, but its intelligent control system and energy-saving design have also significantly reduced our operating costs

4、 Collaboration value: Efficiency improvement and competitiveness leap

Double R&D efficiency

The single testing cycle has been shortened from 8 hours to 3 hours, saving over 2000 hours of testing time annually and accelerating product iteration speed;

Support parallel testing of multiple products, increasing laboratory utilization by 30%.

Quality control upgrade

Through rigorous temperature testing, the failure rate of Chuangrui automotive products has been reduced by 40%, and T ü V Rheinland certification has been successfully passed, obtaining market access qualifications in Europe;

The accumulated test data provides a quantitative basis for product optimization, helping to improve the performance of its high-voltage platform products by 15%.

cost optimization

Modular design reduces maintenance costs, with an expected 30% reduction in maintenance expenses within 5 years.

5、 Future outlook: Deepening cooperation and sharing the market

Based on this successful cooperation, Chuangrui Automotive and Aipei Technology have signed a long-term strategic cooperation agreement, planning to jointly develop a "comprehensive environmental testing system for automotive grade components", integrating multiple stress coupling testing functions such as temperature change, humidity, and vibration, further shortening the product development cycle. At the same time, Aipei Technology will assist Chuangrui Automotive in establishing a CNAS accredited laboratory to provide technical support for its localization layout.

Conclusion

This cooperation not only demonstrates the technical strength of Aipei Technology in the field of ultra high speed temperature change testing equipment, but also creates a full chain reliability guarantee system for Chuangrui vehicles from research and development to mass production through the dual wheel drive of "technology+service". In the future, both sides will continue to drive innovation and jointly promote China's new energy vehicle electronics industry towards higher standards.
