Customized Transformer Heat Sinks and Flat Radiators

Transformer heat sinks, also known as flat radiators, are essential cooling components used in oil-immersed transformers. They play a critical role in dissipating heat generated during transformer operation, ensuring stable performance, extended service life, and improved energy efficiency. These radiators are widely applied in both domestic and international power systems.

Advanced Manufacturing Process

The flat radiators are manufactured using high-quality cold-rolled steel strips, formed into fully corrugated plates to maximize heat dissipation surface area. The plates are assembled through precision spot welding and continuous seam welding to form a unified and robust structure.

CO2 gas shielded welding technology is used to connect the plates to the oil collector, effectively eliminating internal welding defects such as slag inclusion and iron filings. This advanced process significantly enhances product reliability and prevents contamination that could affect transformer insulation performance.

Strict Quality Control and Testing

Each radiator undergoes rigorous sealing tests to ensure leak-proof performance under operating conditions. Surface treatment processes improve corrosion resistance, making the product suitable for outdoor and harsh environments.

Additionally, hot oil flushing is performed to remove impurities and ensure internal cleanliness before installation. These strict quality control procedures guarantee consistent performance and long-term operational stability.

Compliance with Industry Standards

All technical specifications fully comply with JB/T5347-1999, the industry standard for laminated radiators for transformers. The product also meets the requirements of JB15347-2013, ensuring compatibility with modern transformer systems and international engineering practices.

Flexible Installation and Application

These transformer radiators are designed for large and medium-sized power transformers, reactors, and similar equipment. They can be directly mounted onto the transformer tank flange or installed independently on supporting brackets near the transformer, offering flexible configuration options based on site conditions.

Efficient Cooling Solution for Power Equipment

With optimized structural design, high-quality materials, and advanced manufacturing techniques, customized transformer heat sinks provide efficient thermal management for oil-filled transformers. They enhance cooling efficiency, reduce operating temperatures, and contribute to the safe and reliable operation of power systems.
