More Information
Summary:A lithographic device includes a cooling device for removing heat from a motor. The cooling device has a cooling element provided in thermal contact with at least part of the motor. The cooling device further has a cooling duct assembly with a supply duct to supply a cooling fluid to the cooling element, and a discharge duct to discharge the cooling fluid from the cooling element. A pump causes the cooling fluid to flow through at least part of the cooling duct assembly. A flow control device controls a flow rate of the cooling fluid through at least part of the cooling duct assembly, to maintain a predetermined average temperature of the cooling fluid in the cooling element.
