Cooling units for high power serie LK have been developed for forced cooling with reasonable fans. Caused by new lamella design now an optimal relation of the material to distributed load performance is possible; independent of the technical limits for extrusions. For mounting semiconductors modules there are two mounting surfaces. The technical data refer to one flat milled surface by distributed load and free blowing operation. For double side device mounting the other side can also be milled flat. For corrosion protection all aluminium elements are chromated (RoHS-conformm). Height and breadth of the lamella cooled units are in accordance to the commercial fans. The length can be varried in the limit given by the air volume of the fan. The shown standard versions have been optimated by computer calculations with the fan data. Special design, adapted to your construction data, is possible. Test samples can be made in short time. Also a computer supported calculation is possible by an adequate requirement. Technical data: - The fan is only available in 220V - Dissipated power PV at D J = 40 K: 625 W - Maximum thermal resistance Rth max.: 0,064 K/W - Minimum thermal resistance Rth min.: 0,044 K/W - Air temperature rise at J U = 35°C: 0,013 K/W - Material of cooled unit: AlMgSi 0,5 F 22 - Finish: CR (chromate, RoHs-conform) - Mounting surface: milled flat (Rz max. 10µm) - Weight with fan: 5220 g - Weight without fan: 3690 g Mounting and operating instructions The safety regulations in accordance with the laws pertaining to working equipment should be observed. Single-phase motors can only be operated with permitted capacitor. The legal requirements for motor and earth lead connection should be observed.
