Abstract
A compressor that includes a frame, a rotor assembly, and a heat sink assembly. The rotor assembly includes a bearing assembly to which the heat sink assembly is secured. The compressor is configured such that, during use, air is drawn through the interior of the frame. The heat sink assembly then extends radially from the bearing assembly into the air path through the frame such that the air flows over the heat sink assembly.
Claims3
A compressor comprising a frame, a rotor assembly, and a heat sink assembly, wherein the rotor assembly comprises a bearing assembly to which the heat sink assembly is secured, the compressor is configured such that during use air is drawn through the interior of the frame, the heat sink assembly comprises a heat sink that is disc shaped, the heat sink extends radially from the bearing assembly into the air path extending through the frame, and air flows radially over the surface of the heat sink, wherein the heat sink is disposed beneath an impeller with respect to an axial component of the air path, wherein the air flows over the heat sink in a radially inward direction, and wherein the heat sink comprises an outer flange that is secured to the frame by a ring of adhesive.
