Liquid cools drives efficiently

Third Quarter 2007 Electrical switching & drive systems & components

When faced with large power losses classical electric enclosure design requires extensive cooling of the panel using vents. The vent openings in the panel could potentially contaminate the electronic components. In environments with heavy contamination a totally enclosed panel with airconditioning is needed. A technical and economical solution is to liquid cool the drives. Liquid cooling is a very efficient way to dissipate heat.

KEB Combivert F5 is the third generation of UR-approved liquid-cooled drives. The design allows that 70-80% of the power losses are dissipated through the cooling liquid. The anodised LC (liquid cooling) heatsinks are available in five drive housing sizes. Liquid cooled drives can be used in open or closed cycle cooling systems operating at pressures of up to 10 bar.

All LC drives can be provided in a design suited for a complete installation inside the panel or in push-through design that separates the electronics from the cooling circuit. The drives manage the liquid cooling control, eliminating condensation and reducing build up in the heatsink. The temperature management control determines exact consumption of cooling liquids thus reducing waste. A temperature management control for liquid cooled motors (KTY/PT100) is available as an option.

Efficient heat dissipation reduces the temperature in the panel considerably. A lower temperature for electronic components optimises operating conditions and leads to a longer lifetime for the system.
