Abstract
An immersion pump assembly comprises a pump and a wet-rotor motor driving the pump. The motor and the pump have a common shaft which is closable and hollow and which is partly filled with a fluid, for dispersal of waste heat from the rotor chamber of the motor into a heat sink provided by the liquid to be conveyed by means of the pump. The shaft together with the fluid constitutes a rotating heat pipe system.
