Often, air cooling of electrical components is limited, especially when the component must be very compact. To ensure the best possible cooling, a wide range of REO’s inductive and ohmic components are equipped with liquid cooling. These include liquid-cooled resistors and Chokes.
Liquid cooling not only enables optimum temperature behavior of the component, but also promotes performance and ensures a longer service life for the components. The entire body of the component remains at an optimum temperature even under full load.
The initially higher investment costs for the liquid cooling technology are quickly compensated for by a wide range of advantages. First of all, this technology makes it possible to use it in confined spaces where, due to design or protective measures against environmental influences, there is little or no supply and exhaust air. This is because the liquid-cooled components have a significantly smaller size with a high cooling capacity at the same time due to fewer cooling fins. The high efficiency goes hand in hand with a lower noise level, as loud, active fans are not necessary. The advantage increases the higher the ambient temperature. In this case, a technology based on air cooling would very quickly reach its thermal limits and, in contrast to water cooling, lead to a reduction in performance. This is because it is not possible to cool the component below the ambient temperature. The effective dissipation of heat through liquid cooling, on the other hand, leads to a constantly high output and a cooling capacity that can lower the temperature below the ambient temperature.
Another effect of liquid cooling is the lower housing temperature, so that operating personnel are not exposed to any risk of burns and the waste heat does not interfere with other components. As a result, REO products can also be used in industrial applications where assemblies with low surface temperatures are required, such as in the wood and textile industries or in explosion-proof environments. The lower temperature also protects the installed components and extends the service life of the system.
