Cooling systems

An electric drive for a mobile system consists of various components for converting electrical energy into mechanical energy, such as batteries, controllers, cables and motors. Every energy conversion that takes place is accompanied by losses. The losses that occur in the various components result in a conversion into heat. Despite the fact that the components are becoming increasingly efficient and therefore produce less heat, they are also becoming more compact and cooling them remains important. Cooling can take place in different ways, by means of air cooling and liquid cooling. A typical PMDC electric motor, the GVM from Parker with liquid cooling, can deliver 2 to 3 times more power than the same GVM motor with air cooling. Liquid cooling therefore results in a compact solution within the electric drive systems for mobile applications. The efficient and fast dissipation of heat using liquid cooling improves the efficiency and lifespan of components. Parker has the reliable and efficient integrated solution for you here. The Water Glycol QDC cooling system is designed to integrate with the highly efficient GVM motor from Parker in combination with the GVI inverters from Parker. Further simplification of the design allows integration of other components from Parker’s broad product range, including the IQAN control system and integrated sensors.
