Background technology

At the existing electronic product manufacturing power that it produced of need worrying often, damage inner electronic component to avoid electronic product to produce too much used heat in use; And in No. the 096203756th, TaiWan, China utility application and No. 096213721 case, disclose the another kind of technology that strengthens the computer chassis radiating effect respectively.

Yet, in the aforementioned patent case, because its mainboard is close on the plate of back, so its space of fan that this back plate can be installed is very limited, yet in order further to increase heat-sinking capability, strengthen radiating effect so can only increase the fan that is located at housing, the result causes this housing very huge and heavy, and make this housing be difficult for carrying or being placed on narrow and small place, space, though and this radiating mode can effectively improve heat energy by the effect that outwards sheds in the casing, but still not very good, its reason is: though, the fan of this radiating module can be discharged the heat energy in the casing, but the cold air of part radiating module institute suction can be stopped by the electronic installation in the shell when air intake, therefore the discharge of heat energy is not very good, and its setting can't produce good convection current with the external world, so its radiating effect still can be limited to by the space of casing itself; So this radiating module has necessity of further improvement really.

The utility model content

Therefore, the utility model fundamental purpose is providing a heat abstractor that applies to computer chassis, and this device carries out cross-ventilation inside and outside can making casing fully, and the heat energy in the casing is discharged outside to more easily, with equipment and the element in the protection casing.

Therefore, the utility model fundamental purpose is providing a heat abstractor that applies to computer chassis, and this device carries out cross-ventilation inside and outside can making casing fully, and the heat energy in the casing is discharged outside to more easily, with equipment and the element in the protection casing.

For reaching the technological means that above-mentioned purpose takes is to make aforementioned computer heat radiator on casing, comprising:

One casing has the header board and the back plate that are the subtend setting at least, and forms an accommodation space in inside, form a plurality of fan mouths again on the header board, and this back plate forms a mounting groove;

One blower module is in the mounting groove of being located on this back plate; And,

A plurality of fans, this fan are separately fixed in each fan mouth of above-mentioned header board.

With mainboard be located at forward and backward plate in the middle of the place, can make on the forward and backward plate of aforesaid chassis fan and blower module are installed respectively, to strengthen the radiating effect of convection current; And when equipment work in the casing and when producing heat energy, can utilize in the cold air suction casing of fan with the external world of header board and dispel the heat, utilize the blower module of being located on the plate of back that the hot-air in the casing is extracted out again, with the heat energy that device for transferring was produced, and the heat energy in this casing is discharged with convection type, use the raising radiating efficiency.

Embodiment

Please refer to Fig. 1, the utility model is a kind of computer chassis heat abstractor, and it comprises a casing 10, a blower module 30 and a plurality of fan 40.

This casing 10, be to be the hollow, rectangular shape, this casing 10 is not shown in the figures by a base plate 11, a top board, a header board 12, a back plate 13 and biside plate 14 are formed, and form an accommodation space in inside, the a plurality of fan mouths 15 of formation on this header board 12, and this fan mouth 15 again are arranged in a linear to each other, and should form a rectangular-shaped mounting groove 16 on the plate 13 of back, form the more than one reason line hole 17 that caves inward on the one groove edge of this mounting groove 16, for the usefulness of reason line.

Can establish a mainboard 20 and a hard disk unit 50 in said machine casing 10 accommodation spaces, this mainboard 20 is between the header board 12 of subtend and back plate 13, and this hard disk unit 50 is bottoms of being located at casing 10 accommodation spaces, make header board 12 and back plate 13 that redundant space installing blower module 30 and fan 40 are arranged by this, and this blower module 30 and fan 40 can be separately positioned on header board 12 and the back plate 13, be connected with the external world and can establish a plurality of signal line 21 on this mainboard 20, each signal line 21 is to be passed by aforesaid reason line hole 17.

This blower module 30 is provided in a side of on the mounting groove 16 of casing 10 back plates 13, mainly formed by a board 31 and a plurality of fan 32, this board 31 is provided with a plurality of ventilating openings that are arranged in a linear 33, each fan 32 is to be screwed together in respectively on the ventilating opening 33 of this board 31, so that will dispel the heat in the cool ambient air suction casing 10; And each fan 40 is to be screwed together in respectively on the fan mouth 15 of header board 12, makes heat energy that this mainboard 20 produced by extracting out in the casing 10, to be dissipated into the external world.
