Description

The improved device of central controller heat radiation

The utility model relates to a kind of improved device of central controller heat radiation, is meant a kind of improved device that can effectively increase the central controller heat radiation of radiating fin sheet number especially.

Press, the known computer heat radiation apparatus relevant with the utility model, as shown in Figure 4, this heating radiator 10 includes: a pedestal 11, be fixed with a plurality of radiating fins 12 at this pedestal 11, this radiating fin 12 is made by sheet metal Curved Continuous Zhe, is provided with a framework 13 in radiating fin 12 peripheries again and is fixed on the pedestal 11, must borrow this framework 13 to be used for fixing a fan 20.During use, borrow the central surface of contact of pedestal 11 bottoms to contact with central controller (CPU) 30 end faces on the motherboard, the thermal energy conduction that central controller (CPU) 30 is produced when operating is shed by this radiating fin 12, and can further cooperate fan 20, dispel outside the host computer housing hot gas is compulsory.

As above-mentioned known radiating fin 12, it forms down " U " font and " U " font respectively at each fin upper/lower terminal and constitutes when making with sheet metal Curved Continuous Zhe; Therefore, " U " font end face that falls in the radiating fin upper end can form a blocking surface 121, when the fan above this radiating fin 20 was blown down radiating airflow, the air channel area that at first has half was hampered by this blocking surface 121, and reduces its radiating efficiency and can produce great noise; In addition, the sheet number that folds of the integral heat sink fin 12 that this conventional devices can be fixed on the pedestal of fixed measure is less, and therefore, it can't reach preferable radiating effect naturally, so this conventional devices is had necessity of improvement more in fact.

The purpose of this utility model is to provide a kind of improved device of central controller heat radiation, it mainly is the sheet number that effectively increases radiating fin, to increase the integral heat sink area, it has low manufacturing cost and can reduce wind resistance noise and the sheet number that folds that increases fin, improves the radiating efficiency of this heating radiator.

The purpose of this utility model is achieved in that a kind of improved device of central controller heat radiation, mainly comprise the bottom can with the contacted pedestal of central controller end face, but and be located at the plurality of radiating fins of base top surface and the framework of a fan attachment, it is characterized in that: this plurality of radiating fins forms with sheet metal Curved Continuous Zhe, and each radiating fin Zhe wherein becomes " V " font, and approach a central axis with the tip of each radiating fin, and this heat radiating fin loop is set as cylindrical radiation-like, and becoming the joint face punching out of " U " font that opening is arranged in the curved Zhe of each hot fin other end, this cylindrical radiating fin device bottom surface and pedestal connect to one again.

Described pedestal the inside is concaved with ring-shaped groove just can be ccontaining and keep the out of roundness that sets firmly cylindric radiating fin thereon.

The sheathed spring retaining ring of described radiating fin outer rim is between pedestal and framework, and respectively have a slotted hole in this spring retaining ring two side-prominent pedestals outsides and respectively have a downward protuberance in the slotted hole both sides, can borrow this slotted hole with one " 7 " font fastener, have a button hole in this fastener lower end and collude and close with the central controller pedestal.

Described base bottom surface sets firmly a spring retaining ring with riveted or screw-in version, and respectively is provided with button hole in these spring retaining ring both sides, and is provided with a upwardly extending prominent handle in the button hole place of a side wherein, and borrows this prominent handle to fix or separate the pedestal of button hole and central controller.

Owing to adopt such scheme: can reach preferable radiating effect, can reduce windage and its noise in addition, to increase its economic benefit and practicality.

For making your juror more further understanding and understanding can be arranged, lift a preferable possible embodiments now and cooperate graphic being described in detail as follows structure of the present utility model, device and feature thereof:

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is a three-dimensional combination figure of the present utility model.

Fig. 3 is plane combination embodiment figure of the present utility model.

Fig. 4 is the plane combination embodiment figure of known computer radiator.

Fig. 5 is another embodiment three-dimensional exploded view of the present utility model.

See also shown in Fig. 1,2, the utility model is assembled on the computer motherboard, be used for central controller (CPU) 30 is dispelled the heat, this heating radiator 40 mainly comprises: the bottom can with the contacted pedestal 41 of central controller (CPU) 30 end faces, but and be located at the plurality of radiating fins 42 of pedestal 41 end faces and the framework 43 of a fan attachment 20; It is characterized in that: the plurality of radiating fins 42 in this heating radiator 40 forms with sheet metal Curved Continuous Zhe, and each radiating fin one end Zhe wherein becomes the most advanced and sophisticated 42a of " V " font, other end Zhe becomes the joint face 42b of the broad of " U " font, and the most advanced and sophisticated 42a with each radiating fin approaches a central axis, and this heat radiating fin loop is set as cylindrical radiation-like, and be shaped on opening 42c in the joint face 42b of each radiating fin other end upper punch, make the bottom surface and pedestal 41 fixedly connected being integral of these cylindrical radiating fin 42 devices again.

Please cooperate shown in Figure 3 again according to said apparatus, device of the present utility model is when being used in combination, the air-flow of being sent by fan 20 must flow smoothly laterally all around along the radiating fin 42 of radiation-like, and because of on the outer rim joint face 42b of each fin, all having an opening 42c, and reducing its issuable windage, the air-flow that causes this fan 20 more can blow out in the without hindrance easily gap that heads on each fin both sides; Be closely linked because of the most advanced and sophisticated 42a of each fin again, and its outer peripheral edges length is 3.1416 times of diameter, so with identical joint face 42b width and spacing, the utility model can more known radiating fin (as Fig. 4) with " U " the shape joint face is fixed in the pattern of substrate surface, can be provided with the quantity that more fin folds, to increase its area of dissipation, improve its radiating efficiency.
