Heat dissipating motor mounting arrangement

Claim 1

A refrigeration condenser unit comprising: a housing having inlet openings arranged in at least one side of said housing and an outlet arranged in a top wall in said housing and a condenser in said housing arranged in air flow relationship with said openings and said outlet, a fan motor arranged for passing air through said openings between said housing and the ambient surroundings; a split ring motor support member on said motor having an inner portion dimensioned to embrace the outer wall surface of said motor; holding means formed integral with said support member being arranged on the end portions of said ring adjacent said split; clamping means engaging said holding means for urging said end portions toward each other so that the inner contact portion of said support member is maintained in engagement with the outer surface of said motor with sufficient pressure to prevent relative movement therebetween, and to provide a low resistance thermal conductive path between the motor and the motor support member; a plurality of parallel circumferentially spaced heat dissipating means being formed integral with said motor support member projecting radially outwardly and extending substantially the full axial dimension of said support member; support arms including a first end having a non-circular cross section secured to the motor support member at spaced intervals around the circumference thereof and having their other end attached to the wall portion adjacent housing opening so as to center the rotational axis of said motor relative to said opening; arm support elements formed integral with said motor support member and arranged substantially parallel to said heat dissipating means; a non-circular passageway extending through said support elements for receiving said first end of said support arm in mating relationship to secure said arm to said motor support member; a resilient member arranged between said first end of the support arm and said support element passageway for absorbing vibration between said motor support member and said support arms.
