Description
The invention technical field
The present invention relates to a kind of movable heat-pipe apparatus that is used for being reduced in the heat that electronic device accumulates, particularly a kind ofly be used for being reduced in the rotatable of heat that microprocessor chip accumulates and heat-pipe apparatus slidably.
Background of invention
In computer industry, well-known, the microprocessor chip of the P5 type in the present age as the Pentium processor of Intel Company, can produce the heat that can not be ignored when operation.If the heat that processor produces can not suitably be scattered and disappeared, then heat will be accumulated, and the temperature of microprocessor chip is raise, and surpass the maximum operating temperature of its recommendation, thereby performance of processors is produced harmful effect.Continue to increase owing to introduce transistorized quantity in each new processor design, the heat that the chip operation of these renewals is produced also is tending towards increasing, so the accumulation of heat will continue to become the problem of microprocessor chip more of new generation.
Because accumulate the performance generation harmful effect of excessive heat to microprocessor chip, the producer of computer industry and designers adopt various equipment, so that this accumulation of heat problem is made a response.These equipment generally transfer away or lose from this chip and near the circuit it by the heat that microprocessor chip is produced, and keep the temperature of microprocessor chip and near its circuit, make it to be lower than the maximum operating temperature of recommendation.
For example, electric fan is that early stage a kind of being used for remains on the equipment of recommending operating temperature with microprocessor chip.Electric fan or be placed in processor above, hot-air is blown away from chip, or is placed near the processor, cold air is blown on the chip.Yet, use electric fan that some shortcomings are arranged.At first, necessary moving parts make them unreliable in these electric fans.The second, electric fan produces significant noise.The 3rd, using electric fan in needing the portable, battery powered computer of maximum battery life is a shortcoming, because can reduce the battery life of computer to the electric fan power supply.The 4th, the general big comparatively speaking size of electric fan need have bigger space in portable computer, and the space is very valuable in portable computer.The 5th, air circulation enters electric fan can bring dust and fragment.
It is radiator that another kind is used for keeping processor to recommend the equipment of operating temperature.Basically, radiator is by placing with the mode of processor heat exchange, and comprises a metal fever conductive block that is used for heat is delivered to from processor radiator.So the heat that is transmitted scatters and disappears by the surface area of radiator, thereby reduce the heat of in processor, accumulating.Radiator commonly used comprises a plurality of projections, is called fin, and it makes the gross area of spreader surface increase, thereby makes the heat that transmits from processor faster and more effectively lost.
Yet, use an elementary radiator, especially,, some shortcomings are arranged as using in the portable computer that adopts Pentium processor adopting the processor that produces remarkable heat.At first, if processor produces significant heat, then need larger sized radiator fully to lose with the heat that will be produced.Secondly, larger sized radiator certainly will be heavier, and occupy bigger space.Therefore, because the producers of portable computer make great efforts to make their portable machine littler lighter constantly, in the notebook based on Pentium or similar processor, the use of radiator is limited.
Another kind is used for keeping equipment that microprocessor chip recommends operating temperature that the use and the electric fan of radiator are combined.One of benefit of this combination is to use littler radiator.Increase because electric fan makes from the heat dissipation of spreader surface, the less radiator that uses with electric fan can scatter and disappear with the heat of the big radiator as much that does not use with electric fan.But, radiator and the combination of electric fan still be subjected to above-mentioned in the portable machine system obstruction of relevant all shortcomings of the use of electric fan.
Recently, computer manufacturing person have brought into use heat pipe so that more effective, by radiator heat are transferred away from processor more quickly.Heat pipe is used to by radiator heat is delivered to the bottom surface of the keyboard in the portable machine system from processor, so that further dispel the heat.A typical heat pipe comprises and partly fills liquid, as the hollow copper pipe of water.In another alternate embodiment, heat pipe may be made of the solid conductive heat material, or fills various other liquid.Use heat pipe than only with spreader surface area lost can quickly heat being transferred away from microprocessor chip in the air towards periphery, computer manufacturing person can reduce the whole dimension of radiator and the same heat that still can scatter and disappear thus.So,, therefore be preferably in the middle use heat pipe and the littler radiator of portable computer system because littler radiator does not significantly increase the size or the weight of portable computer system.This is littler, radiator that must be bigger when not using heat pipe, and by to place with the mode of processor heat exchange, the first end of heat pipe is fixed on the radiator.The second end of heat pipe is fixed on the metallic plate that is positioned at the keyboard bottom surface.Because heat pipe is that its position of related features is very little on the position fixing with respect to radiator and keyboard, must extra care to guarantee the appropriate placement in computer system of these parts.
The use of heat pipe combines with radiator and keyboard, has reduced or eliminated the many shortcomings relevant with electric fan and heat sink arrangement.For example, owing to do not need power supply to drive heat pipe, thereby the life-span of battery in the portable computer system is reduced.And, do not have dust or fragment to be sucked into and come, there is not the noise of electric fan, there is not the integrity problem of electric fan.In addition, because heat pipe strengthened littler radiator transfers away heat from processor ability, can do radiator littler and lighter.
But, use some shortcoming of mode of heat pipe at present.For example, in present most of portable computer system, processor is installed on the printed circuit board (PCB), and radiator is fixed on the processor, and printed circuit board (PCB) generally is fixed on the portable computer system outer casing bottom.Keyboard is fixed on the shell as lid, in the printed circuit board (PCB) that will comprise processor and radiator is enclosed in.Because in the installation process of heat pipe, heat pipe is to be connected to radiator and keyboard bottom surface rigidly, and is any for safeguarding, repairing or change and live keyboard or the attempt of opening the portable computer system shell all may cause the damage or the bending of heat pipe.For removing keyboard safely or open casing, the user must unload fixing rigidly heat pipe and do not damage or curve heat pipe from radiator or keyboard.
In the design of some portable computers, be turning with keyboard Designing or remove, thus can be with each parts of inside, as battery, hard disk drive, or floppy disk removes, and replaces, or exchange.Because in the installation of present heat pipe, heat pipe is to be connected to rigidly on radiator and the keyboard, adopt the portable computer system of turning or movable keyboard Designing can not utilize the benefit of the heat dissipation that heat pipe provides, may damage heat pipe because keyboard removed.
Therefore, need better solution so that the benefit of heat pipe heat dissipation to be provided, and the shortcoming that not have use of present and heat pipe to accompany.
The general introduction of invention
Movable heat-pipe apparatus of the present invention is used for reducing the heat of accumulating at electronic device, is provided at the benefit of heat dissipation in the portable computer system, and not with prior art in the shortcoming that accompanies of the use of heat pipe.Movable heat-pipe apparatus comprises heat pipe, radiator and heat diffuser.In a preferred embodiment, movable heat-pipe apparatus is used for reducing the heat of accumulating in the electronic device of the portable, battery powered computer system of using the processor that produces remarkable heat.
For example, Intel Company has released recently and has offered computer manufacturing person, carries the Pentium processor chip of encapsulation (TCP) with band.Because their size and weight reduce, so these TCP Pentium processors are mainly used in the portable, battery powered notebook computer system.These TCP Pentium processors are not encapsulated in the ceramic protecting sheathing, but they produce very big heat really.Accordingly, in a preferred embodiment, movable heat-pipe apparatus of the present invention can be used to reduce the heat of accumulating at the TCP Pentium processor that is used for the portable, battery powered notebook computer system.
Movable heat-pipe apparatus of the present invention is designed to its radiator and comprises a necessity, is suitable for holding the cylindrical pipe of the first end of heat pipe.Heat diffuser comprises sheet metal, and its first end is rolled to determine a cylindrical hole that is suitable for holding the second end of heat pipe.Heat pipe is preferably in the bending of two places, form the shape of similar lightning or crank axle, so that first end and the second end roughly are parallel to each other, the mid portion of heat pipe is from disalignment one angle, wherein, center line be defined as one imaginary, between the imaginary parallel lines of determining by the first end of heat pipe and the second end, extend, and the line of almost parallel with it.
Processor generally is positioned on the printed circuit board (PCB), and printed circuit board (PCB) is fixed on the bottom of portable computer system shell.Radiator is by placing with the mode of processor heat exchange, and can be with adhesive on processor, or by a jockey, is fixed on the printed circuit board (PCB) as screwed clip.The first end of heat pipe is slipped into to be constituted in the necessary cylindrical pipe of radiator, and wherein first end is rotatable in cylindrical pipe.Heat pipe is rotated as the rotating crank axle, make the second end of heat pipe be positioned on the height of first end, thereby the cylindrical hole of heat diffuser can be slided on the second end of heat pipe, wherein the second end is rotatable in cylindrical hole.
In a preferred embodiment, heat diffuser is attached on the metallic plate on the keyboard bottom surface.By rotating heat pipe, together with the downward activity of keyboard so that the second end of heat pipe reduces towards the height of first end, thus with keyboard activity to closed position.Because heat pipe rotates in cylindrical pipe and cylindrical hole, radiator and heat diffuser with respect to the horizontal plane keep their direction.By the opposite removable keyboard of step.
In a preferred embodiment, because heat diffuser is attached on the metallic plate below the keyboard, the surface area that the thickness of heat diffuser sheet metal and metallic plate are bigger combines, help by heat pipe from the heat sink to the heat diffuser sheet metal and the heat on the metallic plate of keyboard scatter and disappear quickly.
In another preferred embodiment, the second end of heat pipe is designed to keep and the heat leakage surface, as the movable thermo-contact of the metallic plate below the keyboard, rather than in fact is fixed on the heat leakage surface.
By being rotatable and slidably in cylindrical pipe and cylindrical hole with heat pipe design, and have the pair of curved place, make it to form and the similar shape of crank axle, thereby make the keyboard can be by fast, unload easily or remove, and do not damage and curve the risk of heat pipe.In addition, by being with respect to radiator and heat diffuser rotation with heat pipe design and sliding that the position of related features between these parts increases.Therefore, with the heat pipe that rigidly fixes of the prior art, thereby the execution mode difference that requires in computer system, accurately to place these parts, by permission movable heat-pipe apparatus parts to be placed with lower precision in computer system, movable heat pipe of the present invention has been simplified manufacture process.This is because mobilizable the cooperation cause tolerance to increase between heat pipe and the radiator and between heat pipe and the heat diffuser.
In addition, the structure of this improvement can combine with portable computer system, and it is just removable by opening and remove keyboard simply to make described system be designed to allow the user, replace, or the exchange internal part.Along with heat pipe rotates in cylindrical pipe and cylindrical hole, upwards be separated from the motion of shell together with keyboard, keyboard is by upwards movable to the position of opening, then the first end of heat pipe is skidded off the cylindrical pipe of radiator, or with the second end slippage of the cylindrical hole of keyboard, thereby keyboard can be unloaded from heat pipe.
In the art, well-known, the use of heat conduction lubricating grease can improve the heat transmission between two metal contacts.Because heat pipe, cylindrical pipe, and cylindrical hole do not have desirable smooth surface, between heat pipe and the radiator and the contact area between heat pipe and the heat diffuser have air.Have more the use of the heat conduction lubricating grease of thermal conductivity than air, filled these air-gaps, cause between heat pipe and the radiator and more continuous contact area between heat pipe and the heat diffuser.In a preferred embodiment, if heat-pipe apparatus is the lost enough heats of normal operation of processor, just without heat conduction lubricating grease, because the use of heat conduction lubricating grease increases manufacturing cost.Yet, if be that normal operation needs maximum heat dissipation, should understand, heat conduction lubricating grease can be used in first and second ends of heat pipe, to improve heat pipe and radiator, reach the heat transferred of the contact area between heat pipe and the heat diffuser.
Described above novel rotatable and slidably the use of heat-pipe apparatus benefit is provided, this be before application to be connected to the computer system institute of the heat pipe on radiator and the keyboard rigidly inaccessiable.
Therefore, one object of the present invention provides a kind of improved heat-pipe apparatus, is used for being reduced in the heat that electronic device is accumulated.

Detailed description of preferred embodiment
Fig. 1 illustrates movable heat-pipe apparatus 10, and it comprises heat pipe 20, radiator 30, and heat diffuser 40.Heat pipe 20 comprises first end 22 and the second end 24.Heat pipe 20 has one first bend 26 and second bend 28, and the shape of heat pipe 20 resembles a crank axle like this.
Heat diffuser 40 comprises sheet metal 44, thus an end of sheet metal 44 roll and determine a cylindrical hole 42 that is suitable for holding the second end 24 of heat pipe 20, and allow heat pipe 20 in cylindrical hole 42, to rotate.
Because heat pipe is with respect to radiator and heat diffuser rotates and slip, so the position of related features between these parts increases, thereby place in computer system with lower precision by allowing movable heat-pipe apparatus parts, simplified manufacture process, this be owing between heat pipe and the radiator and heat pipe increase with the movable tolerance that causes that cooperates between the heat diffuser.
Be absolutely necessary though should understand the effect of heat diffuser 40, the actual use with heat diffuser 40 of cylindrical hole 42 is not like this.Will further discuss as following, between all required just heat pipe 20 and the heat leakage surface mobilizable heat exchange be arranged.
Fig. 2-4 is illustrated in the portable, battery powered notebook computer system 56 (not shown display) that adopts movable heat-pipe apparatus 10 of the present invention, keyboard 50 is fixed on required step on the shell 52 of computer system.Keyboard 50 generally has a metallic plate attached to the bottom surface of keyboard 50.Can be with keyboard 50 according to the opposite order that reaches step discussed below shown in Fig. 2-4, remove or unload from the computer system shell, thereby the user can be removed, replace, or the exchange internal part, as battery, hard disk drive, or floppy disk (clear mark parts), and do not damage the danger of heat pipe 20.
Fig. 2 shows the required minimum feature of proper operation of expressing movable heat pipe 20 of the present invention.Various other details of general portable, battery powered notebook computer system are known in the present technique field, and not shown or indicate, because they and operation of the present invention are irrelevant.Fig. 2 illustrates the portable, battery powered notebook computer system 56 (displayless) that radiator 30 is fixed on (processor is positioned at radiator 30 belows, so can't see in the figure) on the processor.Processor is installed on the printed circuit board 58, and radiator 30 and processor thermal coupling, and printed circuit board 58 is fixed on the bottom 60 of computer system shell 52.In another preferred embodiment, radiator 30 usefulness anchor clamps 36 are fixed on the printed circuit board 58.The first end of heat pipe 22 is slided into constitutes the necessary cylindrical pipe 32 of radiator.Shown in heat pipe 20 be rotated on the position of lifting, make its second end 24 be positioned on the height of first end 22.
Now referring to Fig. 3, keyboard 50 links to each other with heat pipe 20 as follows.In a preferred embodiment, the heat diffuser 40 that comprises cylindrical hole 42 and sheet metal 44 is attached on the metallic plate (not shown) below the keyboard 50.Should understand and a cylindrical hole directly can be placed on the bottom surface of keyboard 50, and without the turned up portion of heat diffuser 40 or the metallic plate below the keyboard 50.Like this, shown in the chain-dotted line between the second end 24 of cylindrical hole among Fig. 3 42 and heat pipe 20,, keyboard 50 is linked to each other with heat pipe 20 with heat diffuser 40 by the cylindrical hole 42 of slip heat diffuser 40 on the second end 24 of heat pipe 20.
In addition, the metallic plate of keyboard 50 can be designed to contact with the second end 24 of heat pipe 20, so that further dissipated heat, and need not in fact hold or around the second end 24 of heat pipe 20.For example, heat pipe 20 can so be placed, i.e. the placement of keyboard 50 on shell 52 makes the metallic plate of keyboard 50 contact with heat pipe 20, and need not be in fact the second end 24 of heat pipe 20 be linked to each other with keyboard 50.Should understand that any heat leakage surface all can be used to the metallic plate of substituting for key 50 so that further heat radiation.
As shown in Figure 4, after on sliding into the heat pipe 20 that is lifted, keyboard 50 is moved on to reduction, closed position from the position that is lifted, open, keyboard 50 is movable downwards to its closed position with respect to the shell 52 of computer system.Among this figure, when keyboard 50, when metallic plate and heat diffuser 40 quilts were movable downwards, heat pipe 20 rotated in the counterclockwise direction, and like this, the second end 24 is reduced by the height towards first end 22.Heat pipe 20 rotates counterclockwise, and because heat pipe 20 rotates in the cylindrical hole 42 of the cylindrical pipe 32 of radiator 30 and heat diffuser 40, radiator 30 and keyboard 50 with respect to the horizontal plane keep their direction.
Can keyboard 50 be removed from computer system shell 52 according to the reverse order that reaches step described above shown in Fig. 2-4, thereby the user can be removed, replace, or exchange internal part, as battery, hard disk drive, or floppy disk (unlabelled parts), and do not damage the danger of heat pipe 20.
Should note can be with the concrete Shape Modification of heat pipe for there being any amount of bending, or do not have bending, so that adapt to concrete portable computer system volume inside requirement.Yet the characteristic of crooked quantity opposite heat tube 20 is without any influence.If the keyboard with cylindrical hole is designed to remove by outside slide keypad, and is separated from shell, and does not need at first keyboard to be lifted, then heat pipe can remain the shape of straight line.
In addition, as long as keyboard combines with the attached cylindrical hole thereon of some type, those of ordinary skill in the art just can realize design of the present invention, and without heat diffuser.
Will be further appreciated that in bench device heat diffuser can be placed on other position, rather than below keyboard, because the keyboard of desktop computer is the outside at the computer system cabinet that processor is housed.For example, in desktop computer, heat diffuser can lean on one of computer system cabinet inwall to be sidelong and put, so that improve heat leakage.
In addition, though benefit of the present invention is preferably at the processor based on the remarkable heat of generation, be used in the portable, battery powered notebook computer system as Pentium processor, advantage of the present invention also can be used in any computer system based on processor.And, the heat that any generation is big, and need the chip (being not only microprocessor) of heat dissipation all can have benefited from movable heat-pipe apparatus of the present invention.
Although above description has comprised many specification requirements, these should not be construed as limitation of the scope of the invention, but its preferred implementation for example.Many other different modes also are possible.
