Overview
The Jianhu JH-2026 Thermal Shock Test Chamber is an engineered solution for accelerated reliability assessment under extreme thermal transients. Based on the two-chamber (hot/cold) or single-chamber (air-blast) thermal shock principle, it subjects test specimens to rapid, repetitive transitions between predefined high- and low-temperature extremes—mimicking real-world operational stresses encountered in aerospace avionics, automotive power electronics, semiconductor packaging, and battery module qualification. Unlike general-purpose environmental chambers, the JH-2026 prioritizes metrological integrity over feature density: its core architecture targets reproducible temperature recovery kinetics, spatially uniform thermal distribution, and long-term operational stability under cyclic duty (≥500,000 cycles). Designed and validated per IEC 60068-2-14 (Test N: Change of Temperature), MIL-STD-810H Method 503.6, and GB/T 2423.22–2012, the system supports qualification testing aligned with AEC-Q200, JEDEC JESD22-A104, and ISO 16750-4 requirements.
Key Features
- Dual-Zone Independent Control Architecture: Separated hot (+150 °C) and cold (−70 °C) chambers with pneumatically actuated transfer mechanisms ensure minimal thermal cross-contamination and sub-5-minute recovery times in high-spec configurations.
- Multi-Wing Air Distribution System: Patented asymmetric airflow design with variable-frequency-driven centrifugal blowers achieves ±2.0 °C uniformity across full working volume (per IEC 60068-3-10 Annex B).
- Industrial-Grade Refrigeration Core: Twin-circuit, hermetic scroll compressors (Embraco or Bitzer, depending on capacity tier), pre-aged at −40 °C for 72 h prior to assembly; integrated oil management and low-temperature lubricant formulation ensure >8,000 h MTBF.
- ATEX/IECEx-Certified Options: Explosion-proof variants available with Class II 2G Ex d IIB T4 Gb / Class II 2D Ex tD A21 IP65 enclosures for volatile solvent testing or battery thermal runaway validation.
- Robust Structural Integrity: 304 stainless steel inner chamber, 100 mm polyurethane foam insulation (λ ≤ 0.022 W/m·K), and reinforced door sealing system rated for 100,000+ open/close cycles.
- Calibration-Ready Metrology Interface: Dual PT100 sensors per zone (redundant measurement), traceable to NIM (China National Institute of Metrology); optional third-party calibration certificate (ISO/IEC 17025 accredited).
Sample Compatibility & Compliance
The JH-2026 accommodates diverse sample geometries—from 2-mm-diameter semiconductor dies to 1.2-m-long EV battery modules—via fully customizable internal dimensions and configurable mounting fixtures (e.g., non-conductive ceramic trays, forced-air convection racks, or inert-gas purged sample ports). It complies with key regulatory frameworks governing product safety and data integrity: FDA 21 CFR Part 11 (electronic records/signatures), EU Annex 11 (computerized systems), and GLP/GMP audit readiness via embedded audit trail logging. All firmware and control logic undergo static code analysis and functional safety review per IEC 61508 SIL 2. The chamber’s electromagnetic compatibility meets EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions), verified through third-party EMC testing.
Software & Data Management
Control and data acquisition are managed via the Jianhu ETS-Link™ platform—a deterministic real-time OS (VxWorks-based) with dual Ethernet interfaces (LAN + isolated service port). The GUI supports multi-language operation (English, Chinese, Japanese, Korean), intuitive profile programming (up to 999 steps, 999 cycles), and synchronized logging of temperature, pressure, valve position, compressor status, and alarm history at 1 Hz resolution. Export formats include CSV, PDF test reports (with digital signature), and XML for LIMS integration. Optional cloud connectivity enables remote monitoring, predictive maintenance alerts (via vibration/ampere signature analysis), and automated report generation compliant with ISO/IEC 17025 Clause 7.8.2. Full audit trail—including user login/logout, parameter changes, and manual overrides—is retained for ≥10 years and exportable for regulatory submission.
