Abstract: A cooler for electronic components comprises a heatsink, a blower, and an electric drive with a rotor and a stator. The heatsink comprises heat-exchanging means, inflow and outflow openings, and a base providing thermal contact with said electronic components and said heat-exchanging means. The blower comprises a radial impeller, a casing with an inlet, and heat-exchanging elements that are located in an outflow path of the blower and are in the thermal contact with said heat-exchanging means. The outflow opening of the heatsink being coincided with said inlet of the blower thus cooling gas flows through said heat-exchanging means, said blower inlet, said radial impeller, and said heat-exchanging elements in a series way. The heatsink comprises a cover plate from the high heat conducting material with an outflow opening, and at least a part of said cover plate is made as a part of said casing.

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.
