The disclosed exemplary embodiments are directed to an assembly for removing heat generated by an electronic display.
Electronic displays are now being used in outdoor environments where high ambient temperatures and direct solar loading can cause the displays to malfunction due to excess heat.
The exemplary embodiments disclosed herein provide a heat exchanger assembly for cooling power module bricks, having a plurality of heat exchanger layers where a top layer is in conductive thermal communication with the power module brick. A series of metallic plates are preferably positioned within some or all of the spaces between heat exchanger layers and are preferably aligned with the power module brick. A circulating fan may be positioned to force circulating gas across the power module brick and through the heat exchanger. An external air fan may be positioned to force external air through the heat exchanger. Pass through junctions may be positioned near edges of the heat exchanger to permit the circulating gas to cross paths with the external air without allowing the two gas flows to mix with one another.
This and other unmet advantages are provided by the assemblies and methods described and shown in more detail below.
A better understanding of the disclosed embodiments will be obtained from a reading of the following detailed description and the set of accompanying drawings, wherein:
The general inventive concept is described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.
It will be understood that when an element or layer is referred to as being “on” another element or layer, the element or layer can be directly on another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.
Spatially relative terms, such as “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “lower” relative to other elements or features would then be oriented “upper” relative the other elements or features. Thus, the exemplary term “lower” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
Embodiments of the invention are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The electronic display can be any variety of electronic display 120, including but not limited to liquid crystal display (LCD), LED, OLED, plasma, electroluminescent polymers, field emission display, and laser video displays. In an exemplary embodiment the electronic display 120 would comprise an LED backlit LCD where the rear surface of the electronic display 120 would be the rear surface of the LED backlight.
Further, in an exemplary embodiment, the power modules 250 would be considered high voltage/high power electronics while the electronic assemblies 260 would be considered low voltage/low power electronics and these would be isolated into their own respective plenums. Generally speaking, the electronic assemblies 260 would include, but would not be limited to: hard drives, video players, microprocessors, wireless/satellite antennas, and CPU's. A wiring conduit 275 may provide wiring access into the plenums but should be substantially sealed so as not to allow contaminates or external air to enter the plenum through the wiring conduit 275. The wiring conduit 275 may provide the electrical communication between the low power and high power electronics and also between the low/high power electronics and the electronic display 120.
In an exemplary embodiment, the length and width of the metallic plates 360 are substantially the same as the length and width of the power bricks 350, however this is not required. Ideally, a series of metallic plates 360 may be aligned with each brick 350, such that a layer 205 of the heat exchanger is placed between the brick 350 and the first plate 360, as well as between each subsequent plate 360. While it may not be necessary to place a metallic plate 360 between every heat exchanger layer 205, this may be done in an exemplary embodiment. Each metallic plate 360 may be sandwiched between the layers 205 and may be held in place with adhesive.
The external air is forced through the heat exchanger 201 and exhausted out of the exhaust aperture 225. In this way, heat from the power module 250 may be transferred to the brick 350 and eventually to the plates 360 and heat exchanger layers 205 through conductive heat transfer. The external air removes heat from these assemblies as it passes through the heat exchanger 201.
Additionally, closed loop circulating gas is also travelling through the pathways of the heat exchanger 201, where the gas pathways may be defined as the space between heat exchanger layers 205. The layers 205 may be space apart based on the thickness of the plates 360, and held with this spacing once assembled around the plates 360. In this embodiment, the closed loop of circulating gas is forced around the closed loop by the pair of fans 300 and 301. The loop may be described as beginning at fan 301, traversing the pass through junction 375, travelling through the heat exchanger 201, traversing the pass through junction 370, passing the fan 300, and travelling across the power modules 250 before returning to the fan 301. The gas pathways alternate, where a pathway accepting circulating gas would be adjacent to a pathway accepting external air which is in turn adjacent to another pathway accepting circulating gas. Preferably, the circulating gas and external air are not permitted to mix with one another. However, as the two gases travel through their pathways, heat from the circulating gas can be transferred to the external air and removed from the display housing through the exhaust.
The opposing heat exchanger 202 is setup in a similar fashion as the heat exchanger 201 described above. The only difference would be that heat exchanger 202 would not contain the bricks 350, which are generally not used for the low power/voltage electronics 260. However, the metallic plates 360 may be used in the heat exchanger 202, in order to pull heat from the electronics 260 into the heat exchanger 202 for removal by the external air.
A series of donut gaskets 210 may be placed within each pathway 206 which accepts external air, such that the donut gasket 210 substantially surrounds and seals off the pathway 206 from the opening 371. In this way, external air traveling through the heat exchanger is permitted to flow through the pathway 206, but is not permitted to enter the opening 371 or mix with the circulating gas. The donut gaskets 210 do not preferably run the entire length of the heat exchanger, but would only surround the openings 371, which could be any shape but are typically found as rectangles, squares, circles, ovals, or some combination of these. The interior dimensions of the donut gaskets 210 preferable match that of the cutout 371. However, the exterior dimensions of the donut gaskets 210 can vary.
Although not required, it is preferable that the donut gaskets 210 are comprised of a compressible material, preferably an elastomer or rubber of some type, but soft and compressible materials have been found to provide acceptable results. In some embodiments, the donut gaskets 210 can simply comprise a sheet of compressible material having a void removed from the center, where that void can have any shape, including but not limited to any polygon, circle, or oval shape. Preferably, the donut gaskets 210 would have a continuous perimeter surrounding the void, which is preferably aligned with the opening 371, so that external air is not permitted to enter the opening 371, but can still travel through the pathway 206.
A series of donut gaskets 210 may again be placed within each pathway 206 which accepts external air, such that the donut gasket 210 substantially surrounds and seals off the pathway 206 from the opening 376. In this way, external air traveling through the heat exchanger is permitted to flow through the pathway 206, but is not permitted to enter the opening 376 or mix with the circulating gas. Here, the external air would travel around the donut gasket 210, eventually exiting the heat exchanger and exhausting out of the exhaust aperture 225.
An angled redirection plate 400 is preferably placed after the heat exchanger and adjacent to the exhaust aperture 225 in order to change the direction of the external air approximately 90 degrees, or in other words to direct it towards the exhaust aperture 225.
Another pair of pass through junctions with their own gasket donuts and blocking elements are preferably used for the opposing side of the assembly, which houses the electronics 260. The design could be substantially the same, however in some embodiments it may be possible to use a smaller heat exchanger or perhaps one with fewer layers, as there may be less heat generated by the electronics 260 when compared to the power modules 250. There could also be fewer fans used on this side of the assembly as well.
It should be noted that the term circulating gas does not require a ‘pure’ gas but could be any gaseous matter (which could of course be a mixture of various types of gases and even small amounts of contaminate, but the circulating gas would preferably have only a minimal amount of contaminates, and most preferably would be free of particulate and contaminates).
Having shown and described exemplary embodiments of the general inventive concept, those skilled in the art will realize that many variations and modifications may be made to affect the described embodiments and still fall within the scope of the general inventive concept. Thus, many of the elements indicated above may be altered or replaced by different elements which will provide the same result and fall within the spirit of the general inventive concept. It is the intention, therefore, to limit the general inventive concept only as indicated by the following claims.
This application claims priority to U.S. application Ser. No. 14/198,141 filed on Mar. 5, 2014, which claims the benefit of U.S. Provisional Application No. 61/791,421 filed on Mar. 15, 2013, both of which are hereby incorporated by reference as if fully recited herein.
