Abstract
The utility model relates to an air returning and heat radiating device for a computer, wherein, one side of a circuit board arranged in a machine frame is provided with an air pipe, the air pipe respectively faces to a radiator, and the position of the side end of the circuit board is provided with an opening. A heat radiating fan is arranged on the circuit board, which can guide heat radiating air to enter the air pipe and discharge the heat radiating air from the other discharge hole of the air pipe. The heat radiating air is blown towards the circuit board, in order to achieve the goal that each electronic component arranged below the circuit board can radiate heat. The utility model can effectively improve the heat radiating efficiency of electronic components on the circuit board and can reduce noise.
Description
Technical field
The utility model relates to a kind of heat abstractor, and a kind of computer return air heat abstractor that provides every electronic package that host computer inside is installed to dispel the heat is provided especially.
Background technology
Along with scientific and technological progress of industry, many electronic products all manufacture and design towards miniaturization, sophistication target, and the device of many tool specific functions can be concentrated together the effect that reaches powerful and be convenient to carry.For example, a kind of notebook computer is wherein arranged, its structure is that devices such as circuit board, Winchester disk drive, floppy drive, CD-ROM drive are housed in enclosure interior, and in housing, reserve accommodation space, plug use with card casket as other specific function, so notebook computer can provide data access, transmission and can carry out audio-visual group effect such as puts.
Present employed various types computer, though the reduction of its main frame existing certain degree on volume and weight, to be convenient to portably using of user, but, still can't meet the demands, therefore with trend toward miniaturization at present, the computer industry promptly redesigns at main frame, promptly in main body except the member that is provided with motherboard and relative engagement thereof, remaining peripherals promptly utilizes connector to design in external mode, to reach the requirement with certain miniaturization of main frame and lighting.So under the design, because in the finite space, set electronic package still can produce high heat on the motherboard, this high temperature will have influence on the running and the use of motherboard, be still an important problem so how effectively to dispel the heat.
At present at employed heat abstractor in the miniaturized electric brain server, its structure is to utilize a radiator fan of being located at central processing unit top, and the cooperatively interacting of small-sized fans of being located at the motherboard side, so that reach simultaneously central processing unit set on the motherboard and other set electronic package of upper and lower are dispelled the heat.Commonly use heat abstractor under like this design, higher on the cost of making owing to use two tool small-sized fanses simultaneously, and two tool fans will cause bigger noise in starting together when using, and cause the uncomfortable sensation of user.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of computer return air heat abstractor is provided, make in limited host computer inner space, utilization provides the fan of central processing unit heat transmission to cooperate designed airduct, with guiding heat radiation air the electronic package on other motherboard is carried out effective thermolysis, and have and reduce cost and the purpose of noise-decreasing.
In order to reach aforesaid utility model purpose, the technological means that the utility model used provides a kind of computer return air heat abstractor, wherein in being provided with the frame of circuit board, inside is provided with an airduct, central processing unit top set on circuit board is provided with a fan, one end of the aforementioned airduct heat sink location set with respect to fan is provided with a perforate that can supply air to enter, and its other end is formed with respect to the circuit board side and can supplies the slotted hole of air outflow.
Described computer return air heat abstractor wherein is formed with the space that can pass through for air between the base plate with respect to the circuit board of the slotted hole position of airduct and frame.

Embodiment
Referring to Fig. 1, shown in Figure 2, the designed computer of the utility model return air heat abstractor, wherein the base plate in frame 30 32 is provided with circuit board 31, circuit board 31 is provided with other various electronic package 311 (for example: central processing unit, variant electronic packages such as integrated circuit) and can connects the connector 312 of usefulness for each peripherals, being provided with in addition several in the periphery of frame 30 can be for the through hole 301 of circulation of air, and is formed with a space that can supply air flow at base plate 32 and 31 of circuit boards;
With respect to circuit board 31 the central processing unit place is set, the side is provided with fan 10 and the heating radiator 12 of repeatedly putting combination thereon, this heating radiator 12 reclines mutually with central processing unit and contacts, the support 11 that is provided with fan 10 again can be fixed on the frame 30, being extended by fan 10 sides in addition outwards has a guide card 111, and its free end can (cooperate referring to Fig. 3, shown in Figure 4) above frame 30 is provided with through hole 301 position;
One airduct 20 is hollow form, its end with respect to the position of heating radiator 12 sides is formed with perforate 21, other holds in the side and the bottom is formed with slotted hole 22, after airduct 20 assemblings, its perforate 21 can enter for the heat radiation air with respect to heating radiator 12 positions, and the slotted hole 22 of end is with respect to the placement of circuit board 31 in addition, make the heat radiation air of sending to blow to the side place of circuit board 31, so that each electronic package of circuit board 31 is carried out the cooling effect;
Be respectively equipped with the loam cake 40 and the bottom 50 of tool through hole 41 in the upper and lower of frame 30, promptly form a host computer (as shown in Figure 1) by above-mentioned each member.
When finishing combination and actual the use, extraneous air can be entered via through hole 41 and to heating radiator 12 coolings by the running of fan 10, outside wherein air is sent by through hole 301 via guide card 111 guiding on the one hand, enter airduct 20 via perforate 21 on the other hand, air can be sent by slotted hole 22 through guiding again, and through flowing by the space that forms between circuit board 31 and the base plate 51, so, only by the use of a tool fan 10, can utilize 12 pairs of central processing units of heating radiator directly to dispel the heat, the heat radiation air that flows can be lowered the temperature to other set on the circuit board 31 electronic package simultaneously in addition, reach the effect of heat radiation, escapable cost not only, and owing to only use a tool fan, therefore, its noise that produces is significantly reduced.
