Description

The external hanging type bottom heat spreader of laptop computer

Technical field

The utility model relates to the laptop heat dissipating device, refers to a kind of rear end of laptop computer can being placed on it, with the rear end bed hedgehopping with laptop computer especially, thereby can be by the external hanging type bottom heat spreader of its a kind of laptop computer that dispels the heat.

Background technology

General laptop computer is that volume requirement is thin little, therefore its inner space is very narrow and small, fully use in the space that can utilize, so its heat-dissipating space is littler, and the heat that laptop computer inside is produced almost dispels the heat by its metal shell, but it is relatively poor only to carry out the efficient of heat interchange by metal shell and atmosphere, so can't effectively improve the radiating efficiency of laptop computer.

Thereby have laptop computer is placed on the bottom heat spreader, referring to Figure 11,12, and can cold airflow be blowed bottom to laptop computer, to improve the radiating effect of laptop computer by this bottom heat spreader; And the known bottom heat spreader that is used for laptop computer is to be equiped with a plurality of fan b in a shallow shell a, and be provided with a cushion block a1 at the rear of shallow shell a, laptop computer c can be placed on shallow shell a top, and the cushion block a1 that makes shallow shell a rear leans against the back bottom surface of laptop computer c, with rear bed hedgehopping with laptop computer c, make formation one wedge shape space d between laptop computer c and the shallow shell a and can introduce cold airflow by wedge shape space d both sides by fan b, gas outlet a2 by shallow shell a rear discharges again, and laptop computer c is dispelled the heat by the bottom.

Right this shallow shell a itself promptly has a height h1, after laptop computer c is placed on shallow shell a top, then adds the thickness of laptop computer, and so whole height h is then too high, and therefore inconvenient user manipulates.

Moreover the height of the cushion block a1 at this shallow shell a rear is fixed, and therefore can't adjust the angle of inclination of laptop computer c, freely to adjust angle in response to individual use habit.

The cushion block a1 at this shallow shell a rear is highly fixing again, after making that laptop computer c is placed on shallow shell a top, comparatively the gorge is little for formed wedge shape space d between shallow shell a and laptop computer c, the cold airflow that makes wedge shape space d both sides be introduced is limited, so the poor effect that can reach, and can't effectively improve radiating efficiency.

Summary of the invention

Creator of the present utility model has above-mentioned disappearance thoughts on known bottom heat spreader in order to the radiating efficiency that improves laptop computer, thereby sets about design, designs a kind of external hanging type bottom heat spreader of laptop computer eventually.

So fundamental purpose of the present utility model aims to provide a kind of external hanging type bottom heat spreader of laptop computer, it can lean on the rear end of laptop computer thereon, with the rear end bed hedgehopping of laptop computer, thereby can dispel the heat by this bottom heat spreader.

Another purpose of the present utility model provides a kind of external hanging type bottom heat spreader of laptop computer, and it goes back the wind speed of adjustable cooling device.

Another purpose of the present utility model provides a kind of external hanging type bottom heat spreader of laptop computer, and it also can adjust the forward leaning angle of heating radiator by user's demand.

Another purpose of the present utility model provides a kind of external hanging type bottom heat spreader of laptop computer, and it also has simultaneously parks stable advantage.

The purpose of this utility model is achieved in that a kind of external hanging type bottom heat spreader of laptop computer, includes a heating radiator that is positioned over the laptop computer back lower place; It is characterized in that, this heating radiator is formed a flat housing by a upper and lower casing, heating radiator the place ahead has extended a backing plate, at least one fan of inner installing, the top that the heating radiator top is positioned at fan has an air inlet, the place ahead of backing plate has an air outlet, and heating radiator inside is positioned at the fan below and has a fair water fin; Make backing plate can lean against the back bottom surface of laptop computer, and can discharge by the air outlet in backing plate the place ahead, thereby cooling draught is entered to reach the effect of heat radiation by the laptop computer bottom by fan makes air-flow be entered by air inlet.

Be equiped with wind deflector on the air outlet of described heating radiator, strengthen its radiating effect air-flow on average is scattered in the laptop computer bottom.

The middle part at described heating radiator rear is equiped with supply socket and switch, the resistance of wind speed is adjusted in described switch cross-over connection one, and supply socket and switch the place ahead are equiped with a baffler, thereby have the performance of adjustable wind speed, and avoided electric wire to expose because of being provided with baffler, improved security.

Described heating radiator rear each side is provided with an inclined guide groove, is equiped with the activity mat pin on the inclined guide groove, by the forward leaning angle of mobile activity mat pin with the adjustment heating radiator.

The upper shell rear of described heating radiator each side is provided with a dip plane, and the dip plane is provided with a guide groove, and installing one activity mat pin on the guide groove must be by the activity mat pin to adjust the forward leaning angle of heating radiator.

The backing plate in described heating radiator the place ahead each side is provided with an inclined guide groove, and inclined guide groove is equiped with a foremast pin, leans against angle of inclination on the heating radiator by mobile foremast pin to adjust laptop computer.

The below, the lower house left and right sides of described heating radiator is provided with inclined-plane, the end, and inclined-plane, the end is provided with a chute, and installing one socle in the chute makes by the forward leaning angle of mobile socle with the fine setting heating radiator.

Described heating radiator each side be pivoted with a support, thereby park more stable.

In sum, the utility model makes backing plate can lean against the back bottom surface of laptop computer, and can discharge by the air outlet in backing plate the place ahead by fan makes air-flow be entered by air inlet, add to be equiped with wind deflector on the air outlet, thereby cooling draught is entered to reach the effect of heat radiation by the laptop computer bottom; Because this heating radiator only is positioned over the bottom, the back lower place of computer, reduce the height of integral body when using again, made things convenient for the user to manipulate; And because of being provided with activity mat pin and the mobile socle of adjusting the heating radiator forward leaning angle, therefore can adjust the angle of inclination of laptop computer at any time, to adapt to individual use habit, make the bigger introducing space of formation between laptop computer and heating radiator on the other hand, increase the cold airflow of introducing, can effectively improve radiating efficiency.

Because the resistance of wind speed is adjusted in switch cross-over connection one of the present utility model, thereby the wind speed of adjustable cooling device; The utility model each side is pivoted with a support in addition, thereby parks more stablely, and when not using, can carry out folding again and take parking space with minimizing.
