<p>A liquid cooled elevator machine drive employs a closed circuit coolant circulation system having a heat exchanger, reservoir, pump and piping or tubing (rigid or non-rigid) connected to one or more cold plates which are highly thermally conductive structures through which the coolant flows in the closed circuit. The one or more cold plate(s) are strategically placed with respect to the elevator machine and electronics thereof to maintain controlled temperature operation of the elevator machine drive resulting in enhanced reliability, more compact electronics packaging, reduced acoustic noise over forced convection air-cooled systems and higher performance.</p> |
