Heat transfer system and method for electronic displays

An electronic display unit comprising:

• a sealed display housing;
• an electronic display at least partially inside the display housing;
• at least one circuit board inside the display housing, said at least one circuit board having a plurality of electronic components;
• a plurality of backlighting lamps mounted in metallic lamp end brackets that are oriented about lamp ends to approximately evenly distribute heat among the lamp ends;
• at least one heat collector inside the display housing;
• at least one heat dissipater at least partially outside the display housing;
• and
• a thermally conductive link between the heat collector and the heat dissipater, wherein excessive heat inside the display housing is transferred outside the display housing without exposing the electronic components to dust and moisture from outside the display housing.

A method for transferring heat from an electronic display unit comprising the steps of:

• establishing a thermally conductive link between at least one heat collector inside a display housing and at least one heat dissipater at least partially outside the display housing;
• providing an electronic display at least partially inside the display housing;
• providing at least one circuit board inside the display housing, said at least one circuit board having a plurality of electronic components;
• providing at least three chambers inside the display housing;
• providing a plurality of fan sets inside the display housing, each fan set comprising at least one fan, wherein a first fan set is positioned to circulate air from a second chamber to a first chamber and back to the second chamber and wherein a second fan set is positioned to circulate air from the second chamber to a third chamber and back to the second chamber;
• sealing the display housing from dust and moisture outside the display housing;
• and
• moving heat from areas of higher concentration using at least one fan set to selectively cool overheated locations or warm overly cold locations.

An electronic display unit comprising:

• a sealed display housing;
• an electronic display at least partially inside the display housing;
• at least one circuit board inside the display housing, said at least one circuit board having a plurality of electronic components;
• and
• a plurality of heat transport means inside the display housing for moving heat from areas of higher concentration to selectively cool overheated locations or warm overly cold locations without exposing the electronic components to dust and moisture from outside the display housing.
