Gree Awarded New Patent for Axially Overlapping Ultra-Thin Compressor
Gree Electric has obtained an invention patent authorization for "A Compressor and Its Air Conditioner" (Patent No.: CN202310698443.1) on April 14, 2026, marking a major structural innovation in compressor miniaturization for new energy vehicle and HVAC applications.
Core Technological Breakthrough
The patent features a revolutionary axial overlapping design, where motor and pump assembly are partially overlapped in the axial direction, differing from the traditional series layout.
1. The pump assembly is integrated inside the motor rotor
2. Significantly reduces the overall axial height of the compressor
3. Maintains the original lubrication circuit structure to ensure reliability
Key Application Advantages
1.Ultra-compact Size
Greatly reduces the vertical space occupation, making it highly suitable for new energy vhicle air conditioners and space-constrained cooling scenarios.
2.Stable Performance
Preserves mature oil supply and lubrication systems, avoiding performance or durability compromises while achieving miniaturization.
3.Independent Intellectual Property
As of 2026, Gree has been granted more than 2,000 patents, reinforcing its leading position in domestic compressor R&D and manufacturing.
Industry Significance
This design supports the trend of lightweight and compact thermal management systems for electric vehicles. It also provides a more flexible solution for residential and commercial air conditioners, enabling slimmer indoor and outdoor units while maintaining high efficiency. The technology further strengthens China’s self-reliance in core HVAC components and enhances global competitiveness.
