Homogenous Cooling
Homogenous cooling is essential in many applications. Especially in power modules that comprise several power semiconductors that are switched in parallel and, therefore, need the same operating temperatures. Homogenous cooling is particularly beneficial in wind turbine generators where huge assemblies of large power modules are running in parallel. By tailoring the way, the coolant moves along the module surface intelligently, it is also possible to achieve better cooling at for example, hotspots without jeopardizing the overall cooling efficiency.
In accelerated lifetime tests Shower Power has been able to provide constant cooling performance and secure water tightness for the requested lifetime of the system. Long term investigations at highly elevated temperatures (105°C) result in proven solutions for the 20 years of reliable service required by the wind industry.
By eliminating thermal interface material (TIM), it is possible to reduce complexity in design and increase the reliability of the application. This is especially important in applications that need long lifetimes, where pump-out and dry-out effects of the thermal interface material are known to be problematic. By integrating Shower Power in wind turbines the cost of energy can be reduced, making the wind turbine a more profitable investment.
Shower Power offers the opportunity to design easily scalable power stage solutions. Combined with transfer molded power module technology, Shower Power enables 3D solutions that offer the highest possible power density and great potential in a wide array of applications.
