Novel Thermal Design Reduces Inverter Volume
Lenze has developed 8200 vector inverters using the 'cold plate' technique for cases where the inverter can be mounted directly onto a substantial heatsink. AC Tech (Lenze AG) 8200 Vector Inverters are available for power 0.55 to 90kW with three-phase supply. In the more popular smaller sizes up to 22kW, a space saving variant can reduce the requirement for panel space by up to 40%. By dissipating the heat outside the cabinet, these 'cold plate' versions enable panels to have higher enclosure ratings. Alternatively a plate with external cooling by liquid or air can be used. The cold plate versions of the 8200 vector inverters have no heat fins, so heat generated is passed to the mounting plate and transmitted out of the cabinet. In this way inverters require less mounting depth and the space savings are substantial. For a 1.5kW inverter the saving is 25%, rising to 40% for a 22kW inverter. Therefore panels can be smaller and costs reduced. As the heat is now transmi...
