Abstract
A system and method for cooling an electronic image assembly having a plurality of channels place behind the electronic image assembly. A first fan may be used to force cooling gas through a first grouping of channels while a second fan may be used to force cooling gas through a second grouping of channels. Temperature sensing devices may be positioned so as to measure the temperature of the first and second groupings of channels. The speeds of the first and second fans may be adjusted based on the temperature measurements of the channel groupings. Additional fans with additional temperature sensing devices may be used for further accuracy and control over the temperature gradients of the electronic image assembly. Manifolds may be used to distribute/collect cooling gas to/from the channels.
