Overview
The Tongzhou Weipu MCe Series Integrated Circulating Chiller is a purpose-engineered thermal management system designed specifically for high-duty-cycle, long-duration fatigue testing of power electronics controllers, electric motor inverters, and battery management systems (BMS). Unlike conventional vapor-compression chillers, the MCe operates via direct heat exchange with facility-supplied chilled water or glycol-cooled secondary loops—eliminating onboard compressors, refrigerant circuits, and associated maintenance overhead. This architecture delivers inherently low acoustic emission (<62 dB(A) at 1 m), zero direct F-gas emissions, and up to 40% reduction in electrical consumption compared to compressor-based alternatives under equivalent thermal load conditions. The system maintains precise temperature setpoints across its full operational range (+10 °C to 95 °C) using PID-controlled proportional valves, dual-stage flow regulation, and integrated PT1000 sensor arrays with real-time compensation for inlet temperature drift and pressure drop across test fixtures.
Key Features
- Integrated all-in-one design with built-in circulation pump, expansion tank, filtration module, and digital HMI interface—no external plumbing or auxiliary components required.
- Five selectable flow rate ranges (2–20 L/min through 10–150 L/min) accommodate diverse DUT (Device Under Test) hydraulic impedances—from compact SiC inverter modules to large-format liquid-cooled battery packs.
- High-precision temperature stability of ±1 °C over 24-hour continuous operation, validated per ASTM E740 and ISO/IEC 17025 calibration traceability protocols.
- Corrosion-resistant stainless-steel primary loop (AISI 316L), EPDM-sealed quick-connect fittings, and optional 0.5 µm particulate filtration for compatibility with sensitive semiconductor cooling channels.
- Modular control architecture supports analog (0–10 V / 4–20 mA) and digital (Modbus RTU/TCP, CAN 2.0B) interfaces for seamless integration into automated test benches and PLC-driven validation rigs.
Sample Compatibility & Compliance
The MCe chiller is routinely deployed in laboratories conducting IEC 60068-2-14 thermal shock, ISO 16750-4 environmental stress screening, and SAE J2380 controller durability testing. Its non-refrigerant thermal transfer mechanism ensures full compliance with EU F-Gas Regulation (EU) No. 517/2014 and aligns with UL 61010-1 third-party safety certification requirements for industrial test equipment. All fluid-contact materials meet USP Class VI biocompatibility standards, enabling use in cleanroom-adjacent EV component qualification labs operating under ISO 14644-1 Class 7 conditions. System firmware includes audit-ready event logging and supports GLP/GMP-compliant data archiving when paired with validated SCADA platforms.
Software & Data Management
Embedded firmware provides local control via a 7-inch capacitive touchscreen HMI with multi-language support (English, German, Japanese, Chinese). Remote monitoring and parameter configuration are enabled through standard Ethernet (TCP/IP) and optional Wi-Fi 5 (802.11ac) connectivity. Logged data—including inlet/outlet temperatures, flow rate, pump speed, valve position, and alarm history—is exportable in CSV or .tdms format. For regulated environments, optional FDA 21 CFR Part 11-compliant software packages deliver electronic signatures, role-based access control, and immutable audit trails for all critical configuration changes and calibration events.
Applications
- Dynamic thermal cycling of automotive ADAS domain controllers under simulated road-load profiles.
- Continuous-duty life testing of 800 V silicon carbide (SiC) traction inverters at elevated coolant temperatures (up to 95 °C).
- Thermal boundary condition stabilization during ISO 12405-4 battery cell/module abuse testing (crush, nail penetration, overcharge).
- Steady-state thermal resistance measurement of cold plates used in high-power DC-DC converters.
- Environmental simulation for functional safety validation (ISO 26262 ASIL-D) of redundant controller architectures.
FAQ
Does the MCe chiller require refrigerant charging or periodic compressor servicing?
No—the MCe uses facility-supplied chilled water or glycol solution as its sole heat sink; it contains no refrigerant circuit, compressor, or oil-lubricated mechanical components.
Can the MCe maintain stable outlet temperature when inlet water temperature fluctuates significantly?
Yes—advanced feedforward + feedback control logic dynamically adjusts valve positions and pump speed based on real-time inlet temperature and flow measurements, ensuring ≤±0.8 °C deviation from setpoint even with ±5 °C inlet variation.
Is the system compatible with deionized (DI) water or inhibited glycol mixtures?
Yes—standard configuration supports DI water, 30/70 ethylene glycol/water, and propylene glycol blends. Optional corrosion-inhibitor dosing modules are available for extended loop longevity.
What certifications does the MCe hold for use in North American laboratories?
The unit carries cETLus listing per UL 61010-1 and complies with FCC Part 15 Class A emissions limits. CE marking (EMC Directive 2014/30/EU, LVD Directive 2014/35/EU) is also provided.
How is temperature calibration verified and documented?
Each unit ships with NIST-traceable calibration certificates for all primary sensors. Field recalibration is supported via USB-connected reference thermometers and built-in ISO/IEC 17025-aligned calibration routines.
