Sound abating heat sink and motor housing
First Claim
1. A centrifuge, comprising:
- a rotor configured to receive sample containers;
a drive shaft operatively coupled to the rotor; and
a motor operatively coupled to the drive shaft to rotate the drive shaft and the rotor during a centrifugal operation, herein the motor comprises;
(i) a housing;
(ii) a plurality of substantially parallel fins integral with the housing, each fin having a free end spaced from the housing, wherein the free ends of the plurality of fins are disposed in a common cylindrical plane; and
(iii) a plurality of substantially parallel grooves, each groove disposed between a pair of adjacent fins and having a groove depth defined by a distance between the common cylindrical plane and the housing,wherein the plurality of grooves comprises a first multitude of grooves having a common groove depth and a second multitude of grooves having a groove depth that is not the same as the common groove depth and each of the second multitude of grooves has a different groove depth from each other, wherein the first and second multitude of grooves are interleaved.
