What is a transformer radiator?What is the working principle of transformer radiator?

2025,06,30

Transformer radiator is an indispensable part of power equipment, mainly used to help transformers dissipate heat efficiently and ensure its stable operation.

Transformers generate a lot of heat during operation. If the heat cannot be dissipated in time, the equipment temperature will be too high, affecting performance and even causing failures.

Therefore, transformer radiators optimize the heat dissipation structure, improve cooling efficiency, and ensure the safety and stability of the power system.

Hubei Jutai will answer questions about transformer radiators, working principles, etc. in detail. Users with needs are also welcome to consult product details. Don't miss high-quality transformer manufacturers.

Working principle of transformer radiator

The core function of transformer radiator is to quickly transfer the heat generated inside the transformer to the external environment through natural convection or forced air cooling. Its working principle mainly includes the following key links:

1. Heat conduction: When the transformer is running, the heat generated by the winding and the core is transferred to the surface of the radiator through the insulating oil.

2. Heat sink expands the heat dissipation area: The plate radiator adopts a multi-layer heat sink design, which greatly increases the heat dissipation surface area and improves the heat dissipation efficiency.

3. Air convection heat dissipation: Natural convection or fan forced ventilation allows cold air to flow through the heat sink, taking away heat and reducing oil temperature.

In large substations, a combined heat dissipation solution is usually used, combining a plate radiator and an oil pump circulation system to ensure that large-capacity transformers can still maintain stable operation in high temperature environments.

Transformer radiators are widely used in various power systems, mainly including the following scenarios:

1. Substation

In substations, high-voltage transformers need to run at full load for a long time, and the heat dissipation requirements are extremely high. The plate radiators provided by Hubei Jutai have the characteristics of high temperature resistance and corrosion resistance, and are suitable for the harsh environment of outdoor substations.

2. Industrial power system

Large-scale power equipment in industries such as steel, chemical, and mining rely on efficient heat dissipation solutions. Transformer radiators can effectively prevent equipment from overheating and extend service life.

3. New energy power generation system

The step-up transformers of wind power and photovoltaic power stations also require reliable heat dissipation solutions. With their lightweight and modular design, plate radiators have become an ideal choice in the new energy field.

4. Rail transit and data centers

High-speed rail traction transformers and data center distribution systems have strict requirements on heat dissipation. Customized transformer radiators can meet the heat dissipation requirements of high-density power equipment.

Conclusion

The transformer radiator is a key component to ensure the safe operation of power equipment. Its efficient heat dissipation performance directly affects the life and stability of the transformer. With its excellent heat dissipation performance, the sheet radiator has become the preferred solution for modern power systems.
