On the path of technological innovation, EVOTEC never stops. Recently, two self-developed innovations — “a circulation cooling structure for alternators” and “a marine IP44 low-voltage alternator” — have been officially granted invention patent certificates by the China National Intellectual Property Administration.
This achievement not only affirms the dedication of EVOTEC’s R&D team in overcoming technical challenges, but also stands as strong proof of EVOTEC’s technological leadership in the alternator industry. To date, EVOTEC holds 69 authorized national patents, 23 of which are invention patents, building a solid core technology moat.
Patent 1: A Circulation Cooling Structure for Alternators
Solving thermal challenges, keeping alternators consistently “cool.”
Heat is the natural enemy of alternators; overheating can directly cause efficiency loss or even shutdown. This newly patented “circulation cooling structure” significantly improves heat dissipation
efficiency by optimizing internal flow channel design and heat exchange mechanisms.
· High Efficiency & Energy Savings: A more scientifically designed circulation path reduces energy consumption and improves overall alternator operating efficiency.
· Extended Lifespan: Precise temperature control effectively slows the aging of coils and components, extending equipment service life.
· Compact Design: Achieves maximum cooling effect within limited space, providing technical support for miniaturization and lightweight system integration.
Patent 2: A Marine IP44 Low-Voltage Alternator
The “heart” that conquers the ocean must withstand the test of wind and waves.
The IP44 protection rating means the alternator effectively prevents solid foreign objects larger than 1mm from entering and withstands splashing water from any direction without harmful effects. The granting of this invention patent marks a key breakthrough for EVOTEC in the sealing, corrosion resistance, and reliability of marine power generation equipment.
· Strong Adaptability: Specifically designed for marine and offshore environments, resistant to harsh conditions of high salt spray and humidity.
· Safety Assurance: Low-voltage design combined with high-level protection provides safer operation for crew and vessel electrical systems.
· Stable Output: Maintains stable power supply even under complex rolling and vibration conditions, safeguarding long-distance voyages.
