Abstract

The utility model relates to a heat abstractor of a display card. The heat abstractor is provided with a casing which comprises a bottom board and a cover body. A heat radiating seat and a fan are arranged on the casing one end of which is provided with an internal condensed extending part on which an engageable slide groove is shrink-fitted, the other end of the slide groove is secured on the fastening member which can be fixed on the computer casing. A heat radiating body is arranged under the bottom board, when to use, through the engagement of the extending part, the slide groove and the fastening member, the casing can be moved to front and rear, left and right, thereby the heat radiating seat of the casing centralizes the adjacent display card micro-processing unit or the relative place of high power electric assembly and satisfies requirements of display cards with various sizes. Employing the heating radiating body, the utility model not only enhances heat radiation efficiency, but also avoids the casing touches other electric assemblies of the display card.

Description

The heat abstractor of display card

Technical field

The utility model is a kind of heat abstractor of display card, it is a kind of different size display card that cooperates, and adjust the heat abstractor of radiating seat position with the position change of the microprocessor of described display card or high power electronic assembly, to save manufacturing cost, and can make radiating seat aim at microprocessor or high power electronic assembly, to increase radiating effect.

Background technology

Computing machine is more and more stressed imaging function now, not only the speed of the microprocessor of main frame is more and more fast, the processing speed of the display card of relative engagement is also more and more complicated, for dealing with the function of complexity like this, often must install on the display card and handle high-power microprocessor, so, the heat dissipation problem of display card also becomes a problem that presses for solution.

Please refer to shown in Figure 1; No. 93221004 patent case of TaiWan, China patent; it is a kind of heat abstractor; drawing discloses a display card 100; on these display card 100 1 sides a radiating seat 200 is installed; this radiating seat 200 is provided with a plurality of radiating fins 210; and embedding in the described radiating fin 210 have a fan 220; these radiating seat 200 1 side joints are provided with an airduct 230; this airduct 230 is relative with fan 220, during use, can suck in the radiating seat 200 by the cold air of fan 220 with the external world; discharge by airduct 230 again; but because of this device for fixed, and airduct 230 do not extend on the computer housing edge, so; the heat that regular meeting takes place to be produced still is trapped in the phenomenon of casing inside, and is very undesirable in the use.

Please refer to shown in Figure 2, No. 94200587 patent case of TaiWan, China patent, it discloses a display card 300, these display card 300 1 sides are provided with a flat board 310, this flat board 310 is fixed on (not shown) on the computer housing, and should offer an opening 311 on the flat board 310, in addition, this display card 300 is provided with an airduct 330 of being made up of base plate and cover body on microprocessor 320, these airduct 330 1 ends are provided with the air port, this air port is relative with opening 311, and this airduct 330 is provided with a radiating seat 340, this radiating seat 340 is relative with microprocessor 320, be provided with a fan 350 in radiating seat 340 1 sides, this fan 350 is in airduct 330, and this airduct 330 is provided with fluting 331 on the edge of contiguous fan 350, this kind device construction in use, can be by the opening 311 on dull and stereotyped 310, the air-flow in the external world is imported or discharges, make the unlikely delay display card of heat 300 peripheries, but because of this airduct 330 is fixed, and the air port must be close to opening 311, and the display card of different vendor or different size, the position that its microprocessor is provided with can't be identical, therefore, the position that can't cooperate different display card microprocessors 320, if will change the position of radiating seat 340 in its airduct 330, must make heat abstractor with matching at the display card of different size, cost of idleness not only, and also unusual trouble in the use, moreover, because of this airduct 330 directly posts on microprocessor 320, and the area of this airduct 330 surpasses microprocessor 320, so, be higher than the height of microprocessor 320 as the height of microprocessor 320 peripheral electron assemblies, the phenomenon of damaging then takes place easily.

Summary of the invention

For improving the various shortcomings of above-mentioned existing apparatus structure, the creator is through the permanent research and experiment of making great efforts, and development and Design goes out the heat abstractor of display card of the present utility model finally.

A purpose of the present utility model, be to provide a kind of heat abstractor of display card, to solve the defective that at present existing display card heat abstractor can not broad match uses one-level to damage easily, include on this heat abstractor: a housing, it is to be combined by base plate and cover body, wherein, base plate is provided with radiating seat and fan, and this housing is provided with extension to internal condensation at the end away from fan; One sliding sleeve that moves before and after can be on extension, it is to be linked on the extension; One fixture, it is to combine with sliding sleeve; The composition of the above-mentioned member of mat, when order is used, fixture can be fixed on the computer housing edge, this fixture is adjacent to by the display card, extension with housing moves forward and backward in sliding sleeve again, make housing near or away from sliding sleeve, so that the radiating seat on the housing can be aimed at the microprocessor on the display card, and make the radiating seat on the housing can be, and change its position with the difference of display card microprocessor position.

Another purpose of the present utility model, be to provide a kind of heat abstractor of display card, its base plate has a radiator, this radiator is relative with radiating seat, thus, not only radiator can be placed on the microprocessor, to increase radiating effect, and can make housing and microprocessor keep certain distance, and avoid the electronic package of microprocessor periphery to suffer compression failure.

A purpose more of the present utility model is to provide a kind of heat abstractor of display card, and its fixture is provided with a chute, to adjust the position, the left and right sides of sliding sleeve.

Thus, the beneficial effects of the utility model are: not only can save manufacturing cost, and can increase radiating effect; Not only radiator can be placed on the microprocessor, with the increase radiating effect, and can make housing and microprocessor keep certain distance, and avoid the electronic package of microprocessor periphery to suffer compression failure, use safer.
