摘要

High-brightness LEDs present a special cooling challenge in the design of projectors.rnThermal, acoustic, electrical and optical considerations limit the solution space availablernfor the design of a projector cooling system. This paper will describe how a projectorrncooling system using Pumped Liquid Multiphase Cooling (PLMCTM) addresses each ofrnthese areas, for a commercial theater projection system.rnUse of a non-conductive, inert refrigerant (R-134a) in a pumped, forced convectionrnboiling cooling system is described. Low thermal resistance cold plates are electricallyrnisolated from one another and from the chassis of the projector. Electrically “live” highrnbrightness LED’s are directly attached to the cold plates without the need for electricallyrnnon-conductive thermal interface material. Three cold plates are arranged aroundrncombining optics in a series flow arrangement and each cold plate operates at the samernrefrigerant saturation temperature. The condenser is mounted in the chassis remotelyrnfrom the cold plates and is cooled by ambient air. Performance data for the system willrnbe presented.
