As a global leader in automotive HVAC compression systems, Weixing delivers more than components—we deliver engineered thermal management solutions. With annual sales surpassing the billion-yuan benchmark, our success is built on deep technical expertise and an unwavering commitment to performance, serving a stable, multinational clientele that relies on our precision.
Mastery in Core Compression Technologies
Our portfolio is engineered to meet the exacting demands of modern vehicle architectures:
-
Electric Scroll Compressors: The cornerstone of Electric Vehicle thermal management, our high-voltage scroll compressors provide variable-speed control with exceptional isentropic efficiency and low NVH (Noise, Vibration, and Harshness). They are integral to both cabin comfort and critical battery cooling loops, featuring advanced refrigerant compatibility (R-1234yf/R-744) and robust brushless DC motor integration.
-
Variable Displacement Swash Plate Compressors: For internal combustion engine platforms, our variable displacement designs optimize efficiency by modulating swash plate angle to control piston stroke, reducing clutch cycling losses. Advanced internal control valves precisely manage displacement and suction pressure, ensuring optimal cooling capacity and fuel economy.
-
Fixed Displacement Piston Compressors: Renowned for robustness and cost-effectiveness, our fixed displacement units offer reliable performance, with a focus on high volumetric efficiency and durability under diverse climatic conditions.
Engineering for Peak System Performance
Weixing compressors are designed as system-level enablers:
-
Efficiency Optimization: We focus on minimizing mechanical friction losses, optimizing valve plate design for smoother refrigerant flow, and enhancing heat dissipation from the compressor body to maximize overall coefficient of performance (COP).
-
NVH Mitigation: Through precise rotational balance, advanced muffler design in the suction and discharge chambers, and innovative internal damping, we achieve class-leading acoustic performance.
-
Durability & Sealing: Components are subjected to extreme endurance testing. Critical sealing is ensured through high-precision shaft seal technology and rigorous leak testing with helium mass spectrometry, guaranteeing integrity against refrigerant leakage over the product lifecycle.
Validated Through Rigorous Simulation & Testing
Every design undergoes a gauntlet of virtual and physical validation:
-
CAE Analysis: We utilize advanced Computational Fluid Dynamics (CFD) for refrigerant flow and heat transfer analysis, and Finite Element Analysis (FEA) for structural integrity, fatigue life prediction, and modal analysis.
-
Performance & Environmental Testing: Prototypes are validated on calorimeter benches for capacity and efficiency mapping, and in environmental chambers for operation across extreme temperatures and humidity ranges. Salt spray tests and corrosion resistance protocols validate longevity.
-
Reliability Validation: Our accelerated life testing protocols, including high-speed cyclic duty tests and pressure pulse fatigue tests, simulate years of operation to ensure field reliability.
