An example electronic device with which one or more embodiments interact. FIGS. 1 to 3 illustrate an ultra-compact to small sized mobile computer with built-in keyboard, touch pad, and screen, as an example of an electronic device most commonly referred to as a laptop but may go by other names, such as ultrabook, netbook, subnotebook, notebook, smartbook, tablet laptop, ultraportable laptop, and mini laptop. FIG. 1 illustrates the laptop in plan view with internal components diagramed in dashed line and internal air movement indicated by dashed lined arrows. FIG. 2 illustrates the laptop in cross-section with internal cooling fan, rear vent, and a built-in screen opened, with phantom lines showing screen movement. FIG. 2A illustrates an enlarged view of FIG. 2 with open screen air movement. FIG. 3 illustrates the laptop in front perspective view with an external monitor and external keyboard/mouse.
The laptop has an aluminum enclosure and structural frame 100, with a removable aluminum enclosure bottom panel 102. The laptop has a screen 104 connected to the enclosure 100 by a rotating screen hinge 106 located along the back edge 108. Rotating the screen 104 open exposes a keyboard interface 110 and a touch surface interface 112. The laptop has an air vent 114 located between the hinge 106, the enclosure 100, and the bottom panel 102. The air vent 114 allows airflow in both directions, providing fresh cool intake airflow 116 and waste hot exhaust airflow 118. With the screen 104 in an open position, the air vent 114 has airflow through an open air gap 120 between the screen 104 and hinge 106, as well as airflow through an bottom panel air slot opening 122 along the back edge of the enclosure's bottom panel 102. With the screen 104 in a closed position, the air vent 114 has airflow through the bottom panel air slot opening 122. The air vent 114 leads into an air chamber 124 located between internal electronic components 126 and bottom panel 102. The internal electronic components 126 include a central processing unit (CPU) 128 with an on-chip graphics processing unit (GPU) 130, logic board 132, memory and storage 134, battery cells 136, and a cooling system that consists of an internal cooling fan 138 connected to a heat exchanger 140 with cooling fins connected to a heat pipe 142 connected to heat sink 144 connected to the CPU 128.
The fan 138 pulls cool air 116 through the air vent 114 and into the air chamber 124, where the cool air 116 then passes over and cools the internal electronic components 126, then the fan 138 pulls the cool air 116 through and push it through the heat exchanger 140 to extract heat from the CPU 128 via the heat sink 144 and heat pipe 142, and finally the fan 138 exhausts waste hot air 118 out the air vent 114. When internal laptop temperatures exceed external ambient temperatures, the aluminum enclosure and structural frame 100 and bottom panel 102 absorb heat from internal electronic components 126 and transfers that heat to the surrounding environment by radiation and conduction. Reducing temperature of the laptop's internal electronic components 126, enclosure 100, and bottom panel 102 improves performance, speeds up cool down, reduces heat stresses on all laptop parts, reduces the occurrence of premature failure, and extends overall durability. The laptop's screen 104, keyboard 110, and touch interface 112 operate the laptop. Adding an external monitor 146, external keyboard 148, and/or external mouse 150 supplements or replace the laptop's screen 104, keyboard 110, and touch surface 112. Connecting the laptop to an external power supply 152, external monitor 146, external keyboard 148, and external mouse 150 allows the laptop to operate with the screen 104 closed and without the use of the laptop's screen 104, keyboard 110, and touch surface 112, as shown in FIG. 3.
Another example electronic device with which one or more embodiments interact is shown in FIG. 4, which illustrates a medium to large sized mobile computer with built-in keyboard, touch pad, and screen, as an example of an electronic device most commonly referred to as a laptop but may go by other names, such as notebook, smart book, rugged laptop, gaming laptop, professional laptop, and mobile desktop replacement computer. FIG. 4 illustrates the laptop in plan view with internal components diagramed in dashed line and internal air movement indicated by dashed lined arrows.
This laptop's description and operation is similar to the laptop shown in FIGS. 1 to 3, with the following modifications: The laptop has a larger aluminum enclosure and structural frame 156. The laptop includes a separate dedicated graphic processing unit (GPU) 130. The laptop includes two internal cooling fans 138. The laptop includes side air vents 154 that allows airflow in both directions.

The bottom face 246 has an angle matching the laptop support shelf s 206 angle. The removable pad 242 has countersunk holes 250 corresponding to the laptop support shelf s 206 pad mounting holes 216. A plurality of countersunk fasteners 252 pass through countersunk holes 250 and holes 240 to thread into pad mounting holes 216 and secure the removable pad 242 to the cradle 200. The removable pad 242 can be replaced with a plurality of replacement removable pads 254 with different thicknesses. Two bottom feet pads 256 adhere to the front and the back edges of the bottom 202.
A plastic back cover and fan filter screen 258 fits into and covers the area of the fan pocket 218 and has two power part tabs 260 that fit into and over the area of the power part pockets 224. The back cover 258 slightly overlaps onto the back 212. The back cover 258 has four countersunk holes 262 corresponding to the cradle's 200 fan mounting hole 220 locations. The back cover 258 has a multitude of air holes 264 located between the countersunk holes 262 and covering the area corresponding to the fan pocket 218. The power part tabs 260 each have a power part insert hole 266 centered over each power part pocket 224. A pushbutton on/off power switch 268 inserts and snap-locks into a power part insert hole 266. A power connector jack 270 inserts into the other power part insert hole 266 and locks in place with a nut 272. A removable power connector plug 274 inserts into the power jack 270. The power connector 274 has a power cord 276 that extends to a power conversion unit with wall plug prongs 278. A cable management loop 280 with a strip of hook-and-loop material attaches around and slides up and down the power cord 276. A 12-volt direct-current case fan 282 has a two wire cable connector 284, as well as corner holes 286 corresponding to the fan mounting holes 220 and the countersunk holes 262 locations. A negative wire 288 connects from the power jack 270 to the fan 282. A positive wire segment one 290 connects the power jack 270 to the power switch 268 and a positive wire segment two 292 connects the power switch 268 to the fan 282. Tape secures negative wire 288, positive wire segment one 290, and positive wire segment two 292 onto the fan 282. Four countersunk fasteners 294 insert through the back cover's 258 countersunk holes 262 and the fan's 282 corner holes 286, and thread into fan mounting holes 220. The countersunk fasteners 294 and the fan alignment tabs 222 secure and align the fan's 282 position within the fan pocket 218.
The embodiment has sufficient width, depth, and height to provide stable support for the laptop. The cradle's 200 air exhaust slot 226 and lower pad's 236 air seal lip 238 have an opening of sufficient width and height to deliver cooling air 296 from the fan's 282 into a variety of laptop's vents 114. In addition, the cradle's 200 laptop support shelf 206 and lower pad 236 have a width sufficient for supporting a variety of laptop's without blocking the laptop's vents 114 from exhausting hot air 118, and a height sufficient to allow airflow from the laptop's vents 114. The cradle's 200 air chamber 228 has a sufficient volume and distance between the air intake hole 230 and air exhaust hole 232 to allow the fan's 282 cooling airflow 296 to reach the laptop's vent 114, instead of kicking back against the fan 282.
The removable pad 242 and replacement removable pads 254 have a variety of thicknesses sufficient to allow a variety of laptop thicknesses to press all the way down against the lower laptop pad 236 and air seal lip 238, while having sufficient tightness against the laptop, to press the laptop's vent 114 into the air seal lip 238 so that the air seal lip 238 conforms to the laptop vent's 114 and creates an air seal around the laptop vent 114. The lower laptop pad's 236 air seal lip 238 has compression and flexibility sufficient to conform around the laptop's vent 114 to create an air seal so that fan 282 driven cooling airflow 296 pushes into the laptop's air chamber 124. The top pad 234, lower pad 236, removable pad 242, and replacement removable pads 254 have sufficient thickness, compression, and flexibility to protect the laptop from damage, prevent the laptop from slipping, reduce vibration transfer, and accommodate a variety of laptop sizes and shapes.
The laptop's closed screen operation in combination with the leaned back position of the cradle's 200 laptop support shelf 206 and laptop support back 208, configures the laptop's air vent 114 so that cool airflow 296 drives through the laptop's bottom panel air slot opening 122, through the laptop's air vent 114 into the laptop's air chamber 124, instead of bypassing the laptop's air chamber 124 and exiting through the open air gap 120 created with the screen 104 in an open position. The laptop's closed screen operation allows all CPU 128 and GPU 130 resources to be dedicate to driving an external monitor 148 and provide improve visual and speed performance as compared to using the laptop's screen 104 and the laptop having to divide CPU 128 and GPU 130 resources between both the laptop's screen 104 and an external monitor 146.
The fan 282 has a size and power sufficient to drive cooling airflow 296 into the laptop's intake vent 114 while remaining sufficiently quiet for a work place setting. The fan pocket 218 has a size sufficient to house the fan 282 with sufficient space around the fan 282 for wiring. The power part pockets 224 have a size sufficient to house the power switch 290 and power jack 292. The air holes 264 have a size sufficient to allow airflow while not allowing fingers to pass through the openings.
The fan's 282 use of a 12-volt external power source and the power plug's 278 remote location from the laptop, provide the fan 282 with greater power than a 5-volt source, prevents heat generation that would result from the laptop providing 5-volt fan power, and prevents heat transfer form the power plug 278 to the laptop.
The cradle's 200 aluminum construction, including the aluminum laptop support back 208, provide a thermal heat sink to cool the laptop by absorbing heat radiating from the laptop's enclosure 100 and bottom panel 102.
The cradle's 200 air exhaust slot 226, air chamber 228, fan pocket 218, and power part pockets 224, in combination with the air seal lip 238, fan 282, wiring 288, 290, 292, power switch 268, power jack 270, power connector 274, power cord 276, and power plug 278, pull cool airflow 296 from behind the embodiment and drive cool airflow 296 through the laptop's closed screen position air vent 114, pushing cool airflow 296 over laptop's internal electronic components 126, enclosure 100, and bottom panel 102, cooling the laptop's internal electronic components 126, enclosure 100, and bottom panel 102, feeding cool airflow 296 into the one or more fans 138, increasing the fans 138 efficiency, driving waste hot exhaust airflow 118 out vents 114, driving waste hot exhaust airflow 118 out of side vents 154 if present, flushing out heat, increasing the rate of air exchanges, increasing the laptop's overall cooling capacity, reducing CPU 128 and GPU 130 heat induced performance throttling, improving overall speed, reducing heat stress on internal components, reducing internal cooling fan 138 noise and mechanical wear, allowing the laptop to run at full load, and expanding maximum cooling capabilities enough to allow for CPU 128 and GPU 130 over-clocking upgrades.
The cradle's 200 front 204, laptop support shelf 206, and laptop support back 208, in combination with the top pad 234, lower pad 236, and removable pad 242 provide an elevated and stable support for the laptop to sit and lean at an angled position that takes up less desktop space and prominently displays the laptop as an aesthetic element. The substantially upright laptop position in the embodiment displays the front face of the device, hides cable clutter and other accessories behind the laptop and embodiment, as well as, provides for viewing front facing screens in devices such as tablet conversion laptops and tablets.
The cable management loop 280 collects cables to reduce clutter and clean up workspace appearance, as well as gathering and holding cables in place for a more efficient cable to laptop connection and disconnection process.
The embodiment in combination with the laptop and external input and output accessories, such external monitors 146, external keyboards 148, external mice 150, external hard drives, external speakers and data docks/hubs, provide for improved work station ergonomics as compared with working with a laptop's screen 104, keyboard 110 and touch interface 112.
The embodiment supports and cools a variety of devices with an air vent located near one of the sides, including the example laptops shown in FIGS. 1 to 4 with an air vent 114 located along the back edge 108 at the screen hinge 106.
