New Energy Power parts compressor assembly 8104010-C3330

The assembly adopts brushless DC (BLDC) motor-driven scroll compression technology, specifically optimized for NEV energy efficiency. The scroll compressor design features two interlocking spiral scrolls (fixed and orbiting) that create a series of crescent-shaped compression chambers, enabling smooth, continuous refrigerant compression with minimal energy loss. The BLDC motor operates at variable speeds (1500-6000 RPM) controlled by the NEV’s thermal management ECU, adjusting compression capacity in real time based on cooling/heating demands—reducing power consumption by up to 30% compared to fixed-speed compressors. Additionally, the compressor achieves a high cooling capacity (up to 4.5 kW at 35°C ambient temperature) and heating capacity (up to 3.8 kW at -10°C ambient temperature) for NEV cabin comfort and battery thermal management, ensuring stable performance across a wide temperature range (-30°C to 55°C)

To comply with NEV high-voltage safety standards (e.g., GB/T 18384, IEC 61557), the assembly incorporates multiple safety features:

High-Voltage Isolation: The BLDC motor’s stator windings use class H insulation (180°C rated) with a minimum creepage distance of 15mm and clearance of 10mm, preventing high-voltage leakage (insulation resistance ≥ 100 MΩ at 1000V DC).

Overload & Short-Circuit Protection: A built-in high-voltage fuse (10A rating) and thermal protector (120°C cut-off) safeguard the motor from overload, short-circuit, or overheating, automatically shutting down the compressor if abnormal conditions occur.

IP67 Protection Rating: The compressor housing and electrical connectors meet IP67 dust and water resistance standards, protecting internal components from moisture, dust, and road debris—critical for under-chassis or engine bay mounting in NEVs

Compressor Housing: Constructed from die-cast aluminum alloy (ADC12) with a powder-coated finish (epoxy-polyester hybrid), providing high mechanical strength (tensile strength ≥ 220 MPa) and corrosion resistance (passing 1000+ hours of salt spray testing per ISO 9227).

Scroll Components: The fixed and orbiting scrolls are made of high-strength cast iron (HT250) with a wear-resistant PTFE coating, reducing friction and ensuring smooth operation for 10,000+ hours of service life.

Refrigerant Seals: The inlet/outlet ports use nitrile rubber (NBR) O-rings with a fluorine coating, ensuring leak-free refrigerant sealing (leak rate ≤ 1g/year) and compatibility with low-GWP refrigerants (e.g., R1234yf) commonly used in NEVs.

Bearings: High-precision deep-groove ball bearings (made of chrome steel GCr15) with lithium grease lubrication reduce motor friction and enable quiet operation (noise level ≤ 55 dB at full load)

This compressor assembly meets global NEV thermal management standards, including GB/T 21361 (Automotive air conditioning systems), SAE J2788 (Refrigerant compressors for electric and hybrid vehicles), and IATF 16949 quality management requirements. Each unit undergoes comprehensive pre-shipment testing:

Performance Testing: Measuring cooling/heating capacity, power consumption, and COP (Coefficient of Performance ≥ 3.2 at 35°C) on a dedicated test bench to ensure compliance with NEV thermal demands.

Electrical Safety Testing: Conducting high-voltage withstand tests (2500V AC for 1 minute) and insulation resistance tests to confirm safety compliance.

Durability Testing: Simulating 500,000+ compression cycles (equivalent to 200,000+ km of NEV driving) under variable speed and temperature conditions to ensure no component failure.

Environmental Testing: Exposing the assembly to extreme temperatures (-30°C to 55°C), vibration (10-2000 Hz, 20 g acceleration), and humidity (95% RH at 40°C) to validate performance stability.

Backed by a 36-month manufacturer’s warranty, the assembly ensures reliable thermal management for NEVs in both urban commuting and long-distance driving scenarios
