Abstract
An arrangement for dissipating heat from components producing high heat flux densities, such as computers, features a combination fan and fluid pump with a magnetic coupling () which acts across a fluid-tight partitioning can (). The pump has a pump wheel () connected to a first permanent magnet (), and an electronically commutated internal-rotor motor (ECM) to drive it. The motor has a stator () inside which is rotatably arranged a rotor () equipped with a second permanent magnet (). Interaction between the first and second permanent magnets creates the magnetic coupling (). The stator () of the internal-rotor motor () is arranged radially outside the magnetic coupling (). A first shaft (), arranged on the outer side of the can (), serves for rotatable journaling of the rotor () of the internal-rotor motor () and a second shaft () inside the can serves for journaling the pump rotor.
