Jianhu JH-Series Automotive Thermal Management Environmental Test Chamber

Overview

The Jianhu JH-Series Automotive Thermal Management Environmental Test Chamber is an engineered precision climate simulation system designed specifically for the development, validation, and reliability testing of automotive thermal management systems—including engine cooling modules, HVAC subsystems, power electronics, and battery thermal management systems (BTMS). It operates on a dual-parameter closed-loop control architecture, integrating high-stability Pt100 temperature sensors and capacitive humidity transducers with real-time feedback compensation algorithms to maintain stable, repeatable environmental conditions across extended test durations. Unlike general-purpose environmental chambers, the JH-Series incorporates application-specific thermal mass optimization, low-turbulence airflow distribution, and minimized thermal gradient zones—critical for simulating realistic under-hood or cabin-mounted component exposure profiles. Its operational envelope (15–45 °C / 30–98 % RH) aligns with ISO 16750-4 (road vehicles—environmental conditions and testing for electrical and electronic equipment) and SAE J2352 (thermal management system performance evaluation), making it suitable for functional verification, durability cycling, and failure mode analysis in both ICE and EV platforms.

Key Features

• High-fidelity dual-parameter control: Independent PID-regulated heating, refrigeration, and humidification circuits ensure simultaneous stability in temperature and relative humidity without cross-coupling drift.
• Air-cooled refrigeration system with scroll compressor and microchannel condenser—designed for continuous operation in ambient environments up to 35 °C without external water supply or chiller integration.
• Customizable internal chamber dimensions (standard base: W600 × D600 × H800 mm; scalable upon request) with stainless-steel 304 interior, reinforced insulated walls (100 mm polyurethane foam, λ = 0.022 W/m·K), and double-glazed observation window with anti-fog heater.
• Intuitive 7-inch color touchscreen HMI with multi-language support (English, German, Japanese, Chinese), configurable alarm thresholds, and real-time trend graphing of all monitored parameters.
• Compliance-ready hardware architecture: Optional data logging module with timestamped CSV export, audit trail capability, and optional 21 CFR Part 11-compliant user access control (role-based login, electronic signatures, change history).

Sample Compatibility & Compliance

The JH-Series accommodates full-scale automotive components—including battery packs (up to 150 kg), HVAC evaporator/condenser assemblies, electric motor inverters, and integrated thermal modules—via adjustable mounting rails and load-bearing floor plates (rated to 200 kg uniformly distributed load). Internal airflow velocity is maintained below 0.5 m/s at sample level to prevent convective interference with natural convection-dominated heat transfer in under-hood configurations. The chamber meets EN 60068-2-1 (cold), EN 60068-2-2 (dry heat), EN 60068-2-30 (damp heat, cyclic), and ISO 16750-4 Annex B (temperature/humidity combined stress testing). Optional IEC 60068-2-78-compliant condensation control mode supports accelerated corrosion pre-conditioning per ASTM D2247.

Software & Data Management

Jianhu’s proprietary ChamberControl™ software (v3.2+) enables remote monitoring via Ethernet or Wi-Fi, scheduled profile execution (up to 99 segments per program), and synchronized data acquisition from up to four external analog inputs (e.g., thermocouples, pressure transducers, current sensors). All logged data are stored with ISO 8601 timestamps, sensor calibration IDs, and operator metadata. Export formats include CSV, PDF test reports (with digital signature), and XML for LIMS integration. Firmware updates are delivered via secure HTTPS with SHA-256 signature verification. Calibration certificates traceable to NIM (National Institute of Metrology, China) are provided with each unit, and annual recalibration services comply with ISO/IEC 17025 requirements.

Applications

• Battery thermal runaway propagation studies under controlled humidity ramping (e.g., 40 °C → 60 °C at 95 % RH).
• HVAC system performance mapping across tropical (40 °C/95 % RH) and arid (25 °C/30 % RH) boundary conditions.
• Thermal interface material (TIM) aging validation under 1,000-hour damp heat cycling (85 °C/85 % RH).
• Electronic control unit (ECU) functional safety testing per ISO 26262 ASIL-B environmental stress screening.
• Thermal shock preconditioning prior to mechanical vibration testing (per ISO 16750-3).

FAQ

What standards does the JH-Series chamber comply with for automotive qualification?
It conforms to ISO 16750-4, SAE J2352, EN 60068-2 series, and supports test execution per GMW14872, Ford CETP 00.00-L-467, and VW 80101.
Can the chamber be integrated into an automated test cell with PLC or SCADA systems?
Yes—Modbus TCP and RS-485 (RTU) communication protocols are standard; optional OPC UA server license available for Industry 4.0 integration.
