Lithographic apparatus, and motor cooling device |
摘要 |
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. |

1. A cooling device for removing heat from a motor, the cooling device comprising:
a cooling element provided in thermal contact with at least part of the motor; a cooling duct assembly comprising a supply duct configured to supply a cooling fluid to the cooling element, a discharge duct configured to discharge the cooling fluid from the cooling element, and a recirculating duct configured to connect the discharge duct and the supply duct to each other, the recirculation duct having a first pump; a second pump configured to cause the cooling fluid to flow through at least part of the cooling duct assembly; and a flow control device configured to control a flow rate of the first pump and the second pump, so as to maintain a predetermined average temperature of the cooling fluid in the cooling element. |
