Air-Cooled Thermal Shock Test Chamber  is a rapid temperature transition destructive testing equipment used to evaluate the endurance of products or material structures and composite materials under continuous exposure to extreme high and low temperatures. It simulates harsh environments such as high temperature, low temperature, and rapid temperature changes to test product performance under varying temperature conditions, material reliability, and durability. It plays a critical role in assessing product durability and is an essential device in modern industrial production. It is widely used in optoelectronics, metals, photovoltaics, plastics, silicone, electrical appliances, rubber, electronics, and other material or industrial sectors. It is also commonly employed in consumer electronics, LED lighting, optoelectronics, semiconductors, biotechnology, aerospace, communications, automotive, academic research institutions, medical industries, security industries, information technology, and other industrial product testing.

Equipment Structure

- Three-chamber structure (for some models)

- Low-temperature storage cold zone (used during cold shock)

- High-temperature storage heat zone (used during thermal shock)

- Product testing area (used during thermal shock testing), where test products are statically placed on shelves. Cold or hot air is rapidly introduced via valve control to achieve the shock effect.

- Test chamber

- Provides conditions for placing items and simulating environments. The interior is typically made of stainless steel with excellent corrosion resistance to ensure accurate test results.

- Cooling system

- Utilizes compressor-based refrigeration during testing, with eco-friendly refrigerants for rapid cooling and precise temperature control.

- Heating system

- Employs electric heating during testing, offering fast heating speeds and accurate temperature control.

- Control system

- Features imported PLC and touchscreen (some models use original Japanese or Korean microcomputer large LCD touchscreens with bilingual display controllers). Easy to operate, with multi-group setting storage function, high-precision temperature control, and the ability to monitor temperature changes. Some models can automatically adjust compressor operation for energy-saving conditions, offer automatic and manual defrost cycles, and feature P.L.C. lockout processing for any component action.

- Data acquisition and recording system

- Automatically collects test data and presents it in report form for easy comprehension. Some models support USB connectivity for real-time data recording to USB drives, exporting historical data, importing images, and include standard RS232 communication interface (RS485 optional for some models).

III. Equipment Features

- Appearance and operation

- Design: Curved design with surface spray treatment, high-quality appearance, and flat non-reactive handles for easy and safe operation (some models).

- Observation window: Large, bright, wide-view observation window with triple-layer vacuum-coated glass and Philips energy-saving fluorescent lamps. No need for wipers to defog, ensuring clear visibility to monitor samples inside the chamber at any time (some models).

- Safety features

- Separated humidification system piping and control circuits: Prevents water leakage from affecting electrical circuits, enhancing safety (some models).

- Reliable refrigeration and control system: Uses European and American fully sealed compressors, imported eco-friendly refrigerants, and other refrigeration components. Easy to operate (some models).

- Equipped with automatic circuit and alarm signals for timely alerts during malfunctions. Includes emergency shutdown device in case of unstable power input (some models).

- Functional features

- Capable of independently setting high temperature, low temperature, and thermal shock test conditions. Supports two-chamber or three-chamber structures for thermal shock testing. In addition to rapid shock testing, it also includes standard functions of high-low temperature test chambers (some models).

- High program memory capacity, allowing storage of multiple program groups (some models support up to 100 programs, maximum cycle setting of 9999 cycles, and maximum time setting of 999 hours 59 minutes per segment).

- Equipped with RS-232C communication interface (some models also support USB for direct data export to USB drives, computer connectivity for control/editing/recording, and two dynamic contact points for convenience).

IV. Technical Parameters

- Dimensions

- Multiple internal size options, such as 360x350x400(HxD)MM (50L), 500x400x400(HxD)MM (80L), 600x500x500(HxD)MM (150L), 700x600x600(HxD)MM (250L), 1000x1000x1000(HxD)MM (1000L), etc. External dimensions vary by actual product (contact customer service for more size options).

- Temperature

- Multiple temperature range options, such as -40℃ to +150℃, -55℃ to +150℃, -65℃ to +150℃ (some models offer 0℃, -20℃, -40℃, -60℃, -70℃ to 150℃, etc.). Preheating range for heat storage tank: +60℃ to +200℃; precooling range for cold storage tank: -75℃ to -10℃. Temperature recovery time within 3-5 minutes, transition time within 10 seconds (for some models). Temperature control accuracy up to ±0.2℃ (some models).

V. Usage Precautions

- Before use, inspect the programmable thermal shock tester to ensure all components are undamaged and wiring is correct. Check that heating, cooling, and control systems are functioning properly.

- Set the temperature range and begin testing after programming. During testing, adjust chamber parameters as needed to ensure samples are unaffected by external factors.

- Perform regular cleaning and maintenance during daily use. Keep motor wires clean and protect the external surface of the equipment to avoid scratches or dents.

- Air-Cooled Thermal Shock Test Chamber: During thermal shock tests, implement safety measures in the laboratory to prevent accidents.

- Ensure power supply is within rated voltage range. The equipment is not explosion-proof; do not use water-cooled thermal shock test chambers in environments with flammable or explosive gases (for some models). Do not power on water-cooled thermal shock test chambers before installation and wiring are complete (for some models).
