摘要:
Disclosed herein is an electronic display assembly including a backlight that is positioned to illuminate a liquid crystal display, and a novel cooling mechanism in the form of a thermal plate that is located and configured to transfer heat from the backlight to a thermally conductive housing of the electronic display assembly. The thermal plate is preferably placed in conductive thermal communication with the backlight and with the thermally conductive housing for this purpose. One or more air flow apertures may pass through the thermal plate. A convective cooling loop may also be provided, which cooling loop may include a fan that is located to move cooling air over the thermal plate and/or though one or more apertures in the thermal plate. Both a top and bottom thermal plate may be employed in some exemplary embodiments.

A heat exchanger assembly for an electronic image assembly placed within a housing where ambient air surrounds the exterior of the housing and a rear plate may be placed behind a backlight to create a channel. An ambient air fan may be placed between two portions of a heat exchanger to force ambient air through the heat exchanger. The fan may also be positioned to also force ambient air through the channel. A circulating gas fan may also be placed within the housing to force circulating gas through at least one portion of the heat exchanger.

An electronic display where various electrical components may be removed from a housing of the display and serviced or replaced without having to demount the display. The electronic display may include an electronic image-producing assembly in electrical communication with a backplane. Various electrical components (e.g., electronic assemblies) may be removably connected to the backplane using self-guiding electrical connectors. An access opening through a wall of the housing may be provided to facilitate removal of an electrical assembly through the housing while the display remains mounted to a vertical surface.

An in-field replaceable glass assembly for an electronic display placed within a housing is disclosed. The housing preferably contains a hanger at the top of the housing, where the glass assembly contains a frame surrounding a pane of glass and having a top and bottom. A tab is preferably placed at the top of the frame and adapted to hold the glass assembly in place when slipped over the hanger on the housing. The glass assembly also contains a means for attaching the bottom of the frame to the housing. In some embodiments this means is a threaded post which extends from the frame and passing through a portion of the housing. A nut may be tightened against the post. In other embodiments a threaded fastener may pass through the housing and thread into a female threaded hole within the frame.
摘要:
A system and method for cooling an electronic image assembly having a plurality of cooling gas pathways place behind the electronic image assembly. A first fan may be used to force cooling gas through a first grouping of cooling gas pathways while a second fan may be used to force cooling gas through a second grouping of cooling gas pathways. Temperature sensing devices may be positioned so as to measure the temperature of the first and second groupings of cooling gas pathways. The speeds of the first and second fans may be adjusted based on the temperature measurements of the cooling gas pathway 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 cooling gas pathways.

Disclosed herein is an electronic display assembly having a thermally conductive housing and an image assembly. The image assembly is positioned within the thermally conductive housing and behind a transparent plate assembly. An inlet opening and outlet opening are formed by gaps located between opposing edges of the image assembly and the housing. A space between the image assembly and the plate assembly forms a channel. A thermally conductive plate extends from near the image assembly within each of the inlet opening and outlet opening to contact the housing. Heat from the image assembly is conductively transferred to the housing by the thermally conductive plates. A fan may be positioned to circulate cooling air through the channel via the inlet and outlet openings and apertures in the thermally conductive plates.

Exemplary embodiments provide an electronic display assembly. One or more heat-generating components are preferably placed in thermal communication with a plate. One or more fans are placed to draw cooling air along the plate to remove the heat removed from the component. Some embodiments may place the plate behind the electronic image assembly, so that cooling air can remove heat from the plate as well as the electronic image assembly. Exemplary embodiments have power modules in thermal communication with optional conductive ribs. Conductive thermal communication is established between the optional ribs and the components in the exemplary embodiments.
