This Is How It Works
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 vs Other Cooling Solutions
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.
| Cooling Technology | Maintenance Cost | Power Consumption | Cooling Capacity | Cooling Efficiency | ||||
| Air/Liquid | Complex systems with more components subjected to regular maintenance. | Moderate power consumption and operating cost. | Large systems with high capacity are possible. | High cooling capability with liquids but multiple heat exchangers in systems reduce the overall efficiency. | ||||
| Filtered Air | Filters must be replaced with regular intervals. Very costly offshore. | Low power consumption and operating cost. | High capacity is possible but proof of concept for offshore is not given. | The temperature of ambient air can be utilized for cooling. | ||||
| Heatex Air/Air Solutions |
Self-cleaning heat exchanger and less complex system with minimal maintenance. | Moderate power consumption and operating cost. | Large systems with high capacity are possible. | The temperature of ambient air might not be fully utilized but high efficiency can be achieved with optimized heat exchangers. | ||||
