What are the key design considerations for heat dissipation in R-Type Transformers for high-density installation environments?

1. Core Principles of Heat Dissipation Design

Reducing temperature rise is the primary goal: Compared to traditional EI-type transformers, R-Type Transformers can reduce temperature rise to less than half, demonstrating their low-loss characteristics.
High-efficiency magnetic circuit and low leakage flux: The circular core cross-section reduces leakage flux to less than 10% of that of EI-type transformers, resulting in a more compact magnetic flux path and further reducing heat sources.

Thin structure increases heat dissipation area: Horizontal, thin structures are commonly used, facilitating placement in high-density cabinets while increasing the heat dissipation surface area of​the casing.

2. Optimization of Structure and Materials

High-quality grain-oriented silicon steel strip winding: Cold-rolled grain-oriented silicon steel strip is used, heat-treated and annealed, and impregnated with insulating varnish, formed in one piece, resulting in stable magnetic properties and low thermal resistance.

Circular winding reduces copper losses: The average turn length of circular windings is reduced by 6%-10%, significantly reducing copper losses and generating less heat.

High Thermal Conductivity Plastic Frame: The outer frame uses flame-retardant engineering plastics with excellent thermal conductivity, facilitating rapid heat transfer to the outer casing.
Precision CNC Machining: The company utilizes CNC machine tools to achieve high-precision machining of core components, ensuring tight fit between parts and minimizing thermal contact resistance [Company Advantages mentioned in the text].

3. Heat Dissipation Measures and Layout Techniques

Enhanced Natural Convection: Utilizing a thin outer casing design, sufficient ventilation gaps are left inside the cabinet to promote natural airflow.

Additional Heatsinks or Fans: For high-power models, heatsink mounting positions can be pre-installed on the back of the casing, or low-noise fans can be used for forced cooling.

Use of Thermal Interface Material (TIM): High thermal conductivity silicone grease or thermal pads are filled between the core and the casing to reduce thermal resistance and improve heat transfer efficiency.

Temperature Monitoring and Intelligent Control: A built-in temperature sensor monitors temperature rise in real time, and the control system automatically adjusts the load or activates air cooling when the temperature exceeds a set threshold.
