Abstract:
1. Apparatus for reducing heat in a drive system of an elevator including a motor and a drive for providing a source of power for the motor, the apparatus comprising: at least one heat conducting element in heat exchanging contact with at least one component of the drive system, the at least one heat conducting element having a first portion for receiving heat from the at least one component of the drive system; the at least one heat conducting element being adapted to transfer heat from the first portion to a second portion spaced from the first portion; and a heat exchange device proximate the second portion of the at least one heat conducting element for withdrawing heat from the second portion without the use of a fan to cool the at least one component of the drive system; wherein the heat exchange device is a structural support element of the elevator separate from the motor and the drive that is adapted to exchange heat from the second portion of the at least one heat conducting element at a location spaced from the motor and the drive wherein the structural support element is a bedplate that structurally supports the motor.
