Nanfeng Group Secures National Patent for Breakthrough Immersed Thick-Film Liquid Heater Technology
Nanfeng Group is proud to announce the official grant of China's invention patent for its innovative Immersed Thick-Film Liquid Heater. This technological milestone redefines precision temperature control standards across multiple industries.
The newly patented electric heater has been launched, featuring six key technological upgrades that significantly improve performance and reliability:
1. High Energy Efficiency: Thermal efficiency exceeds 98%, with fully submerged heating plates eliminating heat loss, extending lifespan and improving energy savings.
2. Low-Temperature & High Reliability: Operating temperature reduced to 170°C for more stable performance.
3. Enhanced Safety: Complete isolation between electrical and water chambers prevents condensation and insulation risks.
4. Improved Sealing: Removal of vent valves ensures superior airtightness.
5. Optimized Design: Elimination of heating plate fins simplifies structure.
6. Advanced Manufacturing: Laser welding technology eliminates leakage risks.
This breakthrough innovation sets a new industry benchmark for high performance and safety.
Current applications span one strategic sectors: new energy vehicle battery thermal management (delivering industry-leading temperature uniformity).
