Abstract

An apparatus and method for a centrifugal pump (1) for pumping sensitive biological fluids which includes (i) an integral impeller and rotor (21) which is entirely supported and rotated magnetically by electromagnets (52, 54), (ii) a pump housing (12, 14) and arcuate passages for fluid flow and containment, (iii) a brushless driving motor (40) embedded and integral with the pump housing (12, 14), (iv) a power supply and (v) specific electronic sensing and control algorithms-all fitly jointed together to provide efficient, durable and low maintenance pump operation. A specially designed impeller (21) and pump housing (12, 14) provide the mechanism for transport and delivery of fluid through the pump to a pump output port with reduced fluid turbulence.

Dependent claims

A cooler for electronic devices comprising a heat exchange element and a centrifugal blower,

said heat exchange element having a first heat exchange surface and a second heat exchange surface, said first heat exchange surface having a plurality of continuous wall heat exchange channels and said second heat exchange surface being adapted to provide thermal contact with an electronic device,
said centrifugal blower being positioned on said first heat exchange surface with the periphery of said blower surrounded by said plurality of continuous wall heat exchange channels whereby an outlet of said centrifugal blower is located opposite inlets of said plurality of continuous wall heat exchange channels,
said centrifugal blower comprising a suction path positioned in a central part of said blower and an impeller surrounding said suction path,
said impeller being operable to draw cooling gas into said suction path to cool at least a portion of said first heat exchange surface which is in the vicinity of said suction path and then to flow through said impeller which directs said cooling gas into said plurality of continuous wall heat exchange channels.
