air running separately through the heatexchanger. Air/air heatexchangers thus support active cooling solutions. Active cooling devices and air/water heatexchangers Active cooling devices which also work [...] various cooling concepts. Filter fans and air/air heatexchangers Over a long period, filter fans are the most cost-effective means of thermalmanagement in electrical enclosures, provided the ambient air [...] improves the life expectancy of the electronic components. Air/water heatexchangers on the other hand use cold water for thermalmanagement. They can provide very effective cooling completely independently
