The patent's assignee is
News editors obtained the following quote from the background information supplied by the inventors: "Conventional clamshell computer systems place a video controller and central processing unit (CPU) nearby in the base. The display refresh signals connect to a display housing. Heat generated by the video controller is dissipated in the base of the clamshell computer, with the heat dissipated in the display housing. The base of the clamshell computer is typically designed and constructed to connect and dissipate the heat from the combination of CPU and video controller.
"Liquid cooling systems have sought to take advantage of the large passive area of the display rear enclosure to dissipate heat. Those systems transfer heat from the base through the hinge cavity (using thermally conductive material, including water) and then radiate the heat passively across the surface of the display housing. However, the space that is used for the video graphics adapter (VGA) controller circuitry and its thermal evacuation may be substantial, increasing the size of the base of the clamshell computer. Typically, a small or thin base size is attractive to a user. In addition, thermal evacuation on the base places the heat on the lap of a user and the fans used to remove the heat make noise which may be unattractive."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventor's summary information for this patent application: "Embodiments of various electrical housings, particularly display housings, are provided. In this regard, a representative housing, among others, includes one or more electrical components that are disposed at the housing; a thermal attachment that is designed to transfer heat generated by the one or more electrical components; and a rear enclosure that is designed to engage the thermal attachment. The rear enclosure is further designed to receive and dissipate the received heat from the thermal attachment.
"Other systems, methods, features, and advantages of the present invention will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.
BRIEF DESCRIPTION OF THE DRAWINGS
"Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views,
"FIG. 1 is a perspective view of an embodiment of a clamshell computer.
"FIG. 2 is a schematic view of a clamshell computer, such as that shown in FIG. 1.
"FIG. 3 is a preassembled view of a top housing of a clamshell computer, such as that shown in FIG. 1, having a thermal attachment.
"FIG. 4 illustrates a hot spot on a top housing of a clamshell computer, such as that shown in FIG. 1.
"FIG. 5 illustrates an ideal heat distribution across ear enclosure of a clamshell computer, such as that shown in FIG. 4.
"FIG. 6 is a perspective view of an embodiment of a thermal attachment, such as that shown in FIG. 3.
"FIG. 7 is a perspective view of another embodiment of a thermal attachment and a rear enclosure, such as that shown in FIG. 3, that include isolating members that thermally isolate the thermal attachment from the rear enclosure.
"FIG. 8 includes a preassembled view and a cross-sectional view of another embodiment of a thermal attachment and rear enclosure, such as that shown in FIG. 3, that decrease thermal resistance to the rear enclosure.
"FIG. 9 includes an assembled view and a cross-sectional view of another embodiment of the thermal attachment and rear enclosure, such as that shown in FIG. 8.
"FIG. 10 is a schematic view of another embodiment of a clamshell computer, such as that shown in FIG. 1."
