Company patents
SHENZHEN ENVICOOL TECHNOLOGY CO., LTD.
SHENZHEN ENVICOOL TECHNOLOGY CO., LTD. shows a surprising shift in its patent strategy, moving away from its expected core in Refrigerators & Cold Storage and HVAC & Air Conditioning, which together represent only 23.8% of its portfolio and saw declines of -100.0% and -100.0% respectively so far in 2026. Instead, the company has rapidly increased its focus on Printed Circuits & Electronic Assemblies, which grew by +300.0% in 2025 and now constitutes 38.1% of its portfolio, and Machine Testing, which surged by +700.0% in 2025, indicating an emerging emphasis on semiconductor and manufacturing testing technologies.

Novel designs and configurations for heat exchangers that improve heat transfer efficiency, compactness, or enable specific phase change or separation processes within refrigeration and heat pump cycles.
Heat transfer devices that utilize the phase change of a working fluid (evaporation and condensation) to efficiently move heat, often incorporating capillary structures, heat pipes, or vapor chambers.
Methods and systems for detecting fluid or gas leaks, or assessing the quality and continuity of seals in containers, systems, or structures. This often involves pressure changes, electrical properties, or acoustic analysis.
Design and control strategies for improving the efficiency, stability, and operational flexibility of refrigerant circuits, including component integration, flow management, phase separation, and pressure regulation.
Systems for precisely directing and controlling chilled air within a refrigerator, often creating distinct temperature zones or optimizing cooling efficiency for different compartments.
Integrated systems within refrigerators for dispensing chilled water, ice, or preparing beverages, often including filtration, storage components, and user interface controls.
Technologies focused on improving indoor air quality by removing pollutants, microorganisms, or excess humidity, often employing specialized materials, filtration, or air circulation strategies.
Systems designed to manage the temperature of multiple components in electric or hybrid vehicles, such as batteries, electric motors, power electronics, and the passenger cabin, often using shared or interconnected cooling/heating circuits.
Systems and components designed to store thermal energy, often using sensible, latent (phase change material), or thermochemical reactions, for later release and utilization in various applications.
Software, algorithms, and associated hardware for monitoring, controlling, and optimizing battery performance, safety, and lifespan, including charge/discharge cycles, thermal regulation, and system integration.
