3-Zone Thermal Shock Chamber: Introduction & Applications

The 3-zone thermal shock chamber is a test device for simulating extreme temperature shock environments, composed of a high-temperature chamber, a low-temperature chamber, and a test chamber.

I.  Detailed Introduction

1.1 Working Principle

The high-temperature chamber achieves precise temperature control via heaters and a PID logic circuit, while the low-temperature chamber maintains low temperatures through a refrigeration system. During testing, the sample stays stationary in the test chamber; the control system switches dampers to rapidly inject high/low-temperature air into the test chamber for thermal shock tests.

1.2 Structural Features

Adopting an upper-middle-lower structure (upper: high-temperature; lower: low-temperature; middle: test chamber), its internal/external materials are mostly stainless steel. Insulation materials (superfine glass fiber, polyurethane foam) ensure excellent thermal insulation. A test hole on the left facilitates external power supply and load wiring for component testing.

1.3 Performance Parameters

Programmable temperature shock range: typically -40℃ to +150℃; temperature control accuracy: ±0.2℃; chamber uniformity: ±2℃; maximum shock duration: 999h59min; adjustable cycles: 1-999 times.

1.4 Control & Operation

Equipped with a large color LCD touch controller (Chinese/English interface), it supports independent setting of multiple test specifications, and features real-time status display and curve visualization.

1.5 Safety Protection

Comprehensive protections include power overload, leakage, control circuit overload/short-circuit, compressor, grounding, and over-temperature protection, ensuring reliable long-term operation.

II. Main Applications

• Electronics Industry: Tests performance/reliability of electronic components, PCBs, semiconductors under extreme temperatures to ensure stable operation and reduce after-sales failures.
• Automotive Industry: Evaluates temperature resistance of auto parts (engine, battery, electronic control system, interior materials) by simulating climatic temperature changes, guaranteeing vehicle performance and safety.
• Aerospace Field: Tests aerospace electronics, sensors, aero-engine blades, and materials under thermal shock to ensure flight safety.
• Materials Science: Assesses thermal expansion/contraction and weather resistance of materials, providing data for R&D and application of new materials.
