Abstract
The invention relates to a radiator which comprises cooling fins, a heat sink and a fan. The heat sink which can be attached to a heating source on a circuit board in an abutting mode is arranged below the multiple cooling fins. A heat dissipation channel is formed between every two adjacent fins. At least two guide sheets, namely the first guide sheet and the second guide sheet extend obliquely upward from a board above each fin, wherein a preset inclination angle is formed between the first guide sheet and the second guide sheet in opposite directions. The fan is positioned above the fins. When the fan operates to blow axial wind onto the cooling fins, the first guide sheets and the second guide sheets on the fins are made to face the axial wind generated by the fan to enhance the windward effect so as to lower the wind resistance of the fins, reduce the noise generated during the blowing by the fan, and increase the air volume in the heat dissipation channels. Therefore, heat energy can be quickly taken out and diffused, and the overall heat dissipation effect is better.
Description
Technical field
The invention provides a kind of heat abstractor, espespecially upward the stretching in a plurality of fin upper plate faces place of fin has the first fairlead and the second fairlead that is rightabout pre-determined tilt angle, and toward the axial flow wind of fan, reduce the noise of generation to reduce its windage, air quantity is increased and radiating effect is more good.
Background technology
Computer technology is grown up with the speed of making rapid progress now, make the computer development trend all strong towards calculation function, the fast direction of speed strides forward, the application relevant along with computer trends towards high speed development, also make central processing unit, the temperature that image processor etc. produce when processing computing is higher, therefore work at the temperature that will how to utilize good cooling system that computer is allowed at it, by industry, be considered as very important problem, and the universalness in response to computer, its cooling system is for reaching preferably radiating efficiency and manufacturing cost, just must allow the fin of fin do a variation and make to manufacture instinct effectively to reduce.
Moreover, the current general way of industry, that fin is supported to the pyrotoxin be affixed on circuit board (as central processing unit, image processor, wafer etc.), and after being positioned on fin by fan, just fan and fin collocation can be formed to optimized radiator structure, refer to shown in Fig. 8, three-dimensional exploded view for existing fin, can know and find out in figure, the fin A used now is mostly one-body molded (as aluminium extruded type, molded and shaped) made, its fin A is upwards stood interruption-like a plurality of fin A2 is arranged by pedestal A1, and the arrangement mode of fin A2 is for being an even curface, and fan C is installed in the smooth location, upper surface place of fin A2, again fin A is installed on circuit board B, and make pedestal A1 to being affixed on wafer B1 upper surface, be beneficial to conduct wafer B1 heat energy to fin A, yet when fan C running blows axial flow wind, its axial flow wind is to blow with spiral mode down, and the wind after heat exchange can outwards be overflowed by formed passage between adjacent fin A2, but because of the pedestal A1 of fin A and wafer B1 support paste in the middle of part to absorb heat energy more, and heat energy is conducted around pedestal A1 and a plurality of fin A2, so that the fin A2 of its pedestal A1 centre can absorb heat energy faster than the fin A2 located on every side, make heat hoard in the centre of fin A, integral heat sink area and the radiating effect that can't effectively bring into play fin A are also poor.
In addition, it is in order to increase whole area of dissipation that fin A sets up a plurality of fin A2 on pedestal A1, and the requirement that pedestal A1 is limited on area will make the setting of a plurality of fin A2 more intensive, therefore, the fan C running axial flow wind blowed downwards that produces just can be affected and the tunnel-shaped that can't enter smoothly between adjacent fin A2 becomes windage, and produce great noise, and because the upper surface of fin A2 is smooth contour design, while causing axial flow wind to blow, constant speed concentrates on the centre of a plurality of fin A2, only can be dispelled the heat to the part of fin A, make heat energy will hoard in the centre of fin A, cause the not good disappearance of radiating efficiency and can't effectively dispel the heat.
Therefore the real place, space with improvement of above-mentioned existing fin, and remain to be engaged in this journey dealer, redesign effectively and solved.
Summary of the invention
Therefore, the inventor is because problem and the disappearance that existing heat abstractor is used, be collect related data via assessment in many ways and consider, and utilize the many years of experience of engaging in the industry by constantly studying and revising, begin to design this kind of heat abstractor patent of invention and be born.
Main purpose of the present invention is upward the first fairlead and the second fairlead that has at least two to be rightabout pre-determined tilt angle of stretching in a plurality of fin upper plate faces place of fin, and be formed with heat dissipation channel between each adjacent fin, when the fan running at fin top place, the axial flow wind that can produce toward fan by the first fairlead on fin and the second fairlead increases effect windward, the noise that when to reduce its windage, reducing fan and blow, irregular disturbance is produced, and the stability while guaranteeing fan running, and the air quantity in heat dissipation channel is increased, pyrotoxin on auxiliary circuit board is taken the heat energy of hoarding fast out of to arrange to outside and is fallen apart thus, and then make whole radiating effect more good.
