To ensure the life expectancy of the components inside the nacelle the heat generated by the process of energy conversion and solar radiation needs to dissipate. Heatex develops complete and customized cooling systems.
Customized solutions with proven performance for all types of turbines.
Complete cooling systems with flexible design to meet space and performance requirements.
Closed loop solutions for efficient and reliable cooling of sensitive electronic equipment.
GE Renewable Energy’s Haliade-X, one of the most powerful wind turbines in the world, is cooled by a Heatex custom-made closed-loop cooling system. “With the air-to-air cooling system from Heatex we will reach the cooling required for the Haliade-X generator with a robust and proven technology says Anton Hoang, Head of Sourcing at GE Renewable Energy – Offshore Wind”
Read Case Study
CSIC HZ windpower’s 10MW H210-10.0 turbine was first released in 2019 and features a 210-metre rotor, offering a low 289W/m2 specific power rating specifically aimed at favourable Chinese offshore locations with mean wind speeds above 8.5m/s (IEC class I). It is now in full serial production and operating outside the coast of the Shandong province in China.
When converting between different forms of energy, a part of the available energy is lost, often as heat. In a wind turbine, kinetic energy is converted to electrical energy and the losses are transferred into heat. Generally, larger generators create more heat than smaller versions.
Heatex Air-to-Air Heat Exchangers
In an air-to-air heat exchanger, the outside air passes through the plate heat exchanger on one side of the plate and the air from the nacelle recirculates on the other side. The air coming from the inside of the nacelle is cooled by the outside air through thin aluminium plates.
The outside air, contaminated with salinity, humidity and dust, and the clean dry inside air never mix, creating a closed-loop system and a desirable environment for the electronic components inside the nacelle.
The heat exchanging process depends on differences in temperature between the supply (inside) air and the exhaust (outside) air. Higher differences between these flows require less fan power to transfer the same amount of heat.
To save energy even further, it’s possible to install a VFD, Variable Frequency Drive.
Heatex offers a cooling system that combines the positive aspects of traditional cooling methods while minimizing the drawbacks found in filtered air and liquid-to-air solutions. Heatex air-to-air cooling systems are suitable for both onshore and offshore applications and allow for a high degree of flexibility which makes it possible to retrofit Heatex cooling solutions in existing wind turbines generators.
