'Cold plate' mounting

Mounting an inverter on a substantial metal surface (cold plate) can avoid the need for a the heat sink. This reduces the depth required in the panel – quite substantially so for larger inverters. For example, 250mm reduces to 164mm at 18kW. Lenze now offers a cold plate version of its 8400 StateLine, HighLine and TopLine inverters for single phase supply 0.25 to 2.2kW and three phase 0.37 to 45kW.

An additional design change has resulted in small cold plate inverters up to 3kW having a mounting width reduction from 102 to 70mm. Side by side mounting without a gap is now possible and in this case the volume required in the panel reduces by more than 30% compared to the previous cold plate model. Cold plate inverters are screw mounted onto substantial metal surfaces that are flat, and the use of heat conducting paste is recommended.
