Three tests, one box to solve! Temperature/Humidity/Vibration Three Integrated Chamber, making testing more efficient
Publish Time: 2025-05-06
In high-end manufacturing fields such as aerospace, automotive electronics, and communication equipment, product reliability is directly related to safety and performance. In order to cope with extreme challenges in complex environments, Temperature/Humidity/Vibration Three Integrated Chamber came into being. This device integrates the three core environmental simulation functions of temperature, humidity, and vibration to achieve multi-dimensional environmental stress coupling testing, providing key technical support for product development and quality control.
1. Modular design: flexible adaptation to multiple testing needs
Two-dimensional vibration platform support
The device supports horizontal platform and vertical platform vibration modes. Users can choose single-axis or multi-axis composite vibration testing according to product characteristics. The vibration table adopts an upper and lower roller guide structure, and the anti-overturning moment is increased by 30%, ensuring the stability of the equipment under high-frequency vibration. The maximum acceleration of the vibration system can reach 1200m/s² (sine), which meets the military-grade vibration test standards.
Full-size customization service
The test chamber studio supports customized production from 800×850×700mm to 2000×1500×1800mm, with a volume of 480L to 5400L. The box body uses SUS304 stainless steel liner and polyurethane foam insulation layer with a thickness of 100mm to ensure that there is no condensation on the surface during the wide temperature range test from -70℃ to +150℃. Customers can choose a fixed or hydraulic lifting test platform according to the product size, with a lifting stroke of 1200mm, which is suitable for large equipment testing needs.
2. Intelligent control system: accurate simulation of complex environment
Three-factor independent/cooperative control
The equipment is equipped with a dual-channel PID control system, which can independently perform temperature (-70℃~+150℃), humidity (10%~98%RH) or vibration (0.1~200Hz) tests, and can also realize three-factor dynamic coupling. For example, when simulating a tropical rainforest environment, the temperature can be set to 40°C, humidity to 95%RH and random vibration to 5-500Hz to accurately reproduce the real environmental stress.
Multi-mode vibration control
Supports three modes: sine sweep, random vibration, and impact test. The sine vibration frequency range is 0.1~500Hz, and the amplitude accuracy is ±0.5dB; the random vibration power spectrum density (PSD) control range is 0.01~10g²/Hz, meeting international standards such as MIL-STD-810G and IEC 60068-2-64.
Mobile high and low temperature track
The high and low temperature test track innovatively adopts a magnetic suspension guide rail design, supports a horizontal moving distance of 2500mm, and an adjustable moving speed of 0.1~1m/s. This design makes the equipment compatible with vibration tables of different heights, realizing "one box for multiple tests" and reducing enterprise testing costs.
3. Technological breakthrough: improving test efficiency and reliability
Fast temperature change rate
Through the dual compressor parallel refrigeration and PWM flow control technology, the equipment achieves a heating rate of ≥4℃/min from -40℃ to +85℃ and a cooling rate of ≥1℃/min from +85℃ to -40℃, which is 50% more efficient than traditional equipment and shortens the product development cycle.
Precise humidity control
Dual calibration using dry-wet bulb method and capacitive sensor, the humidity deviation is controlled at ±2%RH (>75%RH) and ±5%RH (≤75%RH). The unique humidity water filtration system can remove impurities in the water and extend the life of the humidifier by more than 3 times.
Redundant safety design
The equipment is equipped with a three-level protection mechanism: the first level is hardware overload protection (automatic power off when current/voltage/temperature exceeds the limit); the second level is software redundant control (dual CPU real-time monitoring); the third level is physical isolation (the vibration table and the test chamber are connected by a silicone rubber soft film to isolate vibration transmission). According to actual measurements, this design reduces the equipment failure rate to 0.02%.
4. Industry application: full process support from R&D to mass production
Aerospace field
In satellite component testing, the equipment passes the -55℃ to +125℃, 10%~98%RH, 5-2000Hz vibration combination test to verify the reliability of electronic components in the space environment, and the fault detection rate is increased by 40%.
Automotive electronics industry
For vehicle controllers, the equipment simulates -40℃ to +85℃, 95%RH, and sinusoidal vibration (5-500Hz) environment to detect the electrical performance attenuation of products under extreme temperature differences and vibrations, helping products pass AEC-Q100 certification.
Communication equipment testing
In the 5G base station module test, the equipment screens out potential solder joint crack problems through 72 hours of continuous random vibration (PSD=0.04g²/Hz) and 85℃/85%RH double 85 tests, reducing the product market repair rate by 65%.
5. Future Outlook: Intelligent and Green Upgrade
With the advancement of Industry 4.0, the three integrated chambers are moving towards intelligence. The new generation of equipment will integrate AI fault diagnosis system and predict equipment life through machine learning; at the same time, it will use CO₂ environmentally friendly refrigerant to reduce energy consumption by 30%. For example, a company has launched a test chamber that supports 5G remote monitoring. Customers can view test data in real time through the cloud to achieve global collaborative research and development.
The Temperature/Humidity/Vibration Three Integrated Chamber solves the problem of single function and low efficiency of traditional test equipment through modular design, intelligent control and technological innovation. Its "one box, multiple tests" capability not only shortens the product development cycle, but also helps companies improve product quality and market competitiveness by accurately simulating complex environments. In the field of high-end manufacturing, this equipment has become an indispensable research and development tool.
