Sound abating heat sink and motor housing |
摘要 |
A centrifuge includes a rotor configured to receive sample containers; a drive shaft operatively coupled to the rotor; and a motor. The motor includes a housing; 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 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 includes 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, wherein the first and second multitude of grooves are interleaved. |

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. |
