Equipment comprising a pump or fan embodiment arranged for connection to a heat exchanger where heat transfer between two media flows is effected by means of co-rotating surfaces. Cavities and rotating disc surfaces are stacked at different levels along a rotating shaft and heat exchange takes place from one level along the rotating shaft to another level. In a counter-flow heat exchanger one of the medias can, from a center channel inlet, enter a cavity between two rotating disc surfaces and then passing the cavity exit the cavity in radial slots at the periphery between two disc surfaces. |
