​​Grand Opening of 2025 China Refrigeration Expo: Innovative Materials Lead the Green and Intelligent Transformation of HVAC Industry​​
On April 27, 2025, the 36th International Refrigeration, Air Conditioning, Heating, Ventilation, and Food Freezing Processing Exhibition (2025 China Refrigeration Expo) commenced at the Shanghai New International Expo Center. Under the theme “Intelligent Connectivity for Cold and Warmth, Sharing a Sustainable Future,” the event brought together nearly 1,200 exhibitors from 32 countries and regions, covering a record-breaking exhibition area of 115,000 square meters. Highlighting innovation under the “dual-carbon” goals, breakthroughs in materials such as ​​high-efficiency heat exchange tubes​​ and ​​fin tubes​​ took center stage, driving the industry toward energy efficiency and intelligent manufacturing.

​​High-Efficiency Heat Exchange Technology: From Industrial Applications to Green Solutions​​

In the core exhibition zone, ​​Qingdao Beibingyang Refrigeration & Heating Energy Technology​​ showcased its self-developed “99 High-Pressure Ratio Heat Pump Centrifugal Unit.” This system integrates ​​ultra-efficient centrifugal compressor technology​​ and ​​eco-friendly refrigerant adaptation solutions​​, utilizing ​​dual-threaded high-efficiency heat exchange tubes​​ to achieve an industrial-grade hot water output of 99°C—a global first for high-temperature heat pumps

. These tubes enhance heat transfer efficiency both internally and externally, reducing energy consumption by over 30% compared to traditional boilers. The innovation attracted immediate trial orders from Middle Eastern and Southeast Asian buyers.

​​Midea Group​​ unveiled its pioneering “C-Type Small-Diameter Fin Tube Heat Exchanger,” featuring φ5mm internal threaded copper tubes and optimized airflow design. This technology, applied in the V8 Series Commercial Air Conditioners, improves heating performance by 20% and reduces refrigerant usage by 30% through ​​multi-row fin tube layouts​​. Such advancements position it as a leading solution for smart building retrofits.

​​Fin Tube Innovations: Manufacturing Excellence Meets Versatile Applications​​

The exhibition spotlighted ​​flanged cold-rolled high-frequency welded fin tubes​​, which combine enhanced thermal conductivity (40% improvement) and durability (16MPa pressure resistance) through seamless high-frequency welding. For instance, ​​Jiangsu Kelinku​​ demonstrated vertical finned microchannel heat exchangers using ​​aluminum fin tube layered designs​​, ideal for high-temperature and corrosive environments. These systems minimize refrigerant usage while optimizing condensate drainage, already deployed in Middle Eastern markets.

​​Zhejiang Xingxing Cold Chain​​ introduced ​​magnetic levitation fin tube technology​​ for refrigeration equipment. Its AI-driven fin tube condenser modules achieve 25% energy savings by dynamically matching cooling loads, propelling the transition to “zero-carbon cold chain logistics”.

​​Industry-Academia Collaboration and Global Partnerships: Building a Sustainable Ecosystem​​

The “Industry-Academia Integration Roadshow Zone” featured joint R&D achievements, such as ​​corrosion-resistant titanium alloy fin tubes​​ and ​​nano-coating heat transfer enhancement technologies​​ by Tsinghua University and Xi’an Jiaotong University. Notably, ​​Midea’s collaboration with Shanghai Synchrotron Radiation Facility​​ produced “photon-enhanced fin tubes,” leveraging advanced material microstructure analysis to boost efficiency by 15%, with mass production slated for 2026.

Globally, ​​Magnetrol Environment​​ expanded into emerging markets like Argentina and Thailand with ​​salt-resistant fin tube systems​​, tailored for Belt and Road Initiative projects. Meanwhile, ​​Xinlei Compressor​​ secured European partnerships through its ​​ultra-low-temperature fin tube heat exchanger patents​​, accelerating the global reach of Chinese core components
