System for Cooling an Electronic Display

A light-emitting diode (LED) assembly comprising:

• a mounting substrate;
• a plurality of LEDs mounted on the front side of the mounting substrate;
• an isolating structure placed behind the mounting substrate;
• a channel defined by the space between the isolating structure and the mounting substrate;
• a power module having electronic components on a first side and a heat sink on the second side, where the power module is attached to the isolating structure so that the heat sink is within the channel and the electronic components are outside the channel;
• and
• a fan positioned so as to draw ambient gas through the channel.

An electronic image assembly comprising:

• an electronic display assembly having a front and rear portion;
• a surface on the rear portion of the electronic image assembly and in thermal communication with the electronic display assembly;
• an isolating structure spaced apart from the surface;
• a first channel defined by the space between the isolating structure and the surface;
• a power module having electronic components on a first side and a heat sink on the second side, where the power module is attached to the isolating structure so that the heat sink is within the channel and the electronic components are outside the channel;
• and
• a first fan positioned so as to draw ambient gas through the first channel.
