Abstract
A system for cooling a mirror such as a laser mirror is provided. The system includes a mirror having a reflective surface and a plurality of coolant chamber cavities arranged in serial order from an inlet to an outlet. Restrictive flow passages formed within walls between the cavities control coolant flow and produce desired turbulence within the cavities for enhanced heat transfer from the mirror to the coolant.
Claims8
In a fluid cooled mirror assembly,
- a generally circular mirror having a reflective surface and a centrally disposed opening therethrough,
- a plurality of coolant chambers beneath said reflective surface of said mirror, said coolant chambers being serially arranged in two generally semicircular arcs from a first one to a last one of said plurality of coolant chambers,
- an inlet in said mirror for admitting coolant fluid to said first one of said plurality of coolant chambers,
- an outlet in said mirror for allowing removal of coolant fluid from said last one of said plurality of coolant chambers, walls formed in said mirror intermediate adjacent ones of said plurality of coolant chambers, and
- coolant passages in said walls interconnecting adjacent ones of said plurality of coolant chambers for flow of coolant fluid from said inlet to said outlet.
