Project Cases
Application of High-Temperature Resistant Aluminum Electrolytic Capacitors in Variable Frequency Air Conditioners
With the maturity of frequency conversion technology, this technology has been widely applied in air conditioning systems. Currently, the power consumption of frequency converters used in air conditioning is relatively high, requiring greater ripple resistance from the aluminum electrolytic capacitors at the input end of the converters. Moreover, since the frequency converters are located on the outdoor unit of the air conditioning system, they are subjected to higher environmental temperatures. In tropical regions of Southeast Asia, the outdoor temperature can be reaching 38-50°C. Therefore, aluminum electrolytic capacitors used in such environments cannot withstand prolonged high-temperature operation, leading to a high failure and maintenance rate. To address this issue, Linkeycon independently developed a high-temperature resistant aluminum electrolytic capacitor for frequency conversion air conditioners in 2018.
Linkeycon capacitors overcomes two current failure characteristics of aluminum electrolytic capacitors under high-temperature conditions: solvent volatilization and electrolyte decarboxylation. By utilizing high-boiling solvents as well as corresponding auxiliary solvents, the electrolyte can tolerate temperatures exceeding 135°C. The method of adding stabilizers has slowed the decarboxylation rate of the electrolyte.
Linkeycon’s high-temperature-resistant aluminum electrolytic capacitors fully meet customer requirements. In terms of lifespan, they can achieve 135°C and 5000 hours under high temperature DC load and high temperature ripple tests, far surpassing the lifespan specifications of similar capacitors from peers at 105°C for 5000 hours or 105°C for 10000 hours. The products have been widely applied in the field of air conditioning inverters, with rapid market growth. Major clients include Midea Group, AUX Group, Shenzhen Ruiling Industrial Co., Ltd., Megatronic, and others,earning trust from customers both domestically and internationally.
Filter low-impedance capacitors
The use of a double-row staggered riveting method instead of the traditional single-row riveting enhances the stability of the connection, reduces the current density at the riveting points, allowing aluminum electrolytic capacitors to better withstand current surges, while also lowering the resistance value and improving the filtering effect.
Superior performance: The traditional design adjusts the riveting position of the plates arbitrarily to meet the spacing of the two leads. This product adopts various methods to adjust the internal structure, ensuring that the leads are precisely riveted at the center of the plates, resulting in a lower impedance value and better filtering characteristics for the designed aluminum electrolytic capacitors.
Quality assurance: The company emphasizes product quality with standardized management. It possesses a professional technical research and development team, an experienced management team, advanced production equipment and processes, and is equipped with complete testing instruments and technical means to effectively ensure product quality.
Market situation: Various specifications and models can meet the diverse needs of customers. The products can be applied in fields such as network communication power supplies, with rapid market growth.
High safety factor small-sized capacitors
This product improves space utilization by reducing the thickness of the electrolytic paper. Openings or cards are set on the winding needle to facilitate the winding of the electrolytic paper. By first winding the electrolytic paper inside the core package, it reduces product failures caused by internal short circuits in aluminum electrolytic capacitors.
Superior performance: The new process allows for more winding counts in the finished core package within the same shell volume, enabling an increase in the capacitance of aluminum electrolytic capacitors by 8-10% without affecting other performance aspects. This effectively enhances the capacitance within the same volume, improving space utilization.
Quality assurance: The company places great importance on product quality, with standardized management practices. It has a professional R&D team and an experienced management team, along with advanced production equipment and processes. It is equipped with comprehensive testing instruments and technical means, effectively ensuring product quality.
Market situation: Multiple specifications and models can meet different customer needs. The products are applicable in the consumer electronics field, with rapid market growth. Users include Midea Group and DIXON TECHNOLOGIES (INDIA) LIMITED, earning strong trust from domestic and international customers.
