Description

The heat abstractor combination

[technical field]

The utility model is about the combination of a kind of heat abstractor, and it is strong and can repeatedly dismantle indeformable heat abstractor combination particularly to hold power about a kind of easy to loading and unloading, button.

[background technology]

Along with integrated circuit develops towards densification, complicated direction, the heat that its electronic component produces also increases severely thereupon.For this reason, the volume and weight of the radiator that industry is selected also increases thereupon, the fixer for heat radiator button is held the also corresponding raisings of performance demands such as strength and intensity.

Radiator such as No. the 412024th, Taiwan patent announcement and United States Patent (USP) the 5th commonly used, 464, No. 054, its fastener by a single medal spring bar bending forming is fixed on the electronic component heating surface, this fastener is squeezed in the radiator groove, and a plurality of barbs by this groove root sidewall are fixed on this fastener on the radiator; And this relative reversed dip in fastener two ends extends an elastic arm, and the free end of this elastic arm further is bent to form a grab, and this grab is buckled in respectively in the clinodiagonal circuit board through-hole of this radiator, thereby makes this radiator be fixed on integrated circuit surface.But the button of this fixture is held strength fixed heat sink effectively, causes radiator very easily to rock even come off because of vibration or situation such as collision produce, and can't reach the expection radiating effect.And this type of fastener needs by big external force this fastener to be snapped in the groove of radiator distorted sidewall, very inconvenience of its assembling.Moreover this type of fixture needs by screwdriver or other special fixture auxiliary operation in disassembly process, causes production efficiency decline, production cost to improve, and very easily damage printed circuit board (PCB) or peripheral precision element because of careless manipulation.

[summary of the invention]

It is strong and can repeatedly dismantle indeformable heat abstractor combination that the purpose of this utility model is to provide a kind of easy to loading and unloading, button to hold power.

The purpose of this utility model realizes by following technical proposal: the combination of the utility model heat abstractor, it comprises identical radiator anchor clamps and the identical fixed leg of two structures of fan fixer, two structures that a radiator, a fan, a backboard, two symmetrical sheets are formed.The base both sides of this radiator fixing ear that stretches out, this fixedly offers through hole on the ear, and the fin two sides of this radiator are provided with fluting; This fan fixer comprises a roof and the sidewall vertical with this roof, the sidewall outer surface of this fan fixer is provided with a protrusion tab, its roof inner surface is to having two projections, these projections are used for and the shrinkage pool of four jiaos of ends of fan matches, the inwardly outstanding clasp that forms of this fan fixer side wall lower ends, this clasp is used to fasten the fluting of radiator fins; These radiator anchor clamps comprise a base, and these base central authorities have a fixing hole, and this base convexes with a projection respectively in the longer both sides of fixing hole, and an end of this projection is the inclined-plane, and the edge of this base extends a pulling part obliquely.

The advantage of the utility model heat abstractor combination is: it is strong and can repeatedly dismantle indeformable that the combination of the utility model heat abstractor is easy to loading and unloading, button is held power.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

Please refer to Fig. 1, the utility model heat sink arrangement combination, it comprises fan fixer and the identical fixed leg 70 of two structures that a radiator 10, a fan 20, a motherboard 30, a backboard 40, radiator anchor clamps 50, the two symmetrical sheets 60 that two structures are identical are formed.

Four jiaos of ends of this fan 20 offer shrinkage pool 22, offer through hole 32 on this motherboard 30.

Please refer to Fig. 2, this radiator 10 comprises a base 12 and a plurality of fins 14 that extend straight up from these base 12 surfaces, the relative dual-side of this base 12 fixing ear 16 that stretches out respectively, and each fixedly offers a through hole 17 on the ear 16.Establish a groove 18 in the appropriate position, dual-side top of these fins 14.

Please refer to Fig. 3, this fan fixer is made up of two identical symmetrical sheets 60, each symmetrical sheet 60 comprises a roof 61 and a sidewall 62 vertical with this roof, the lateral outer of each symmetrical sheet 60 is stretched out a protrusion tab 63 (please refer to Fig. 7) of being convenient to the manual teardown fan, the roof 61 inner both sides of each symmetrical sheet 60 are respectively to having a projection 64, each symmetrical sheet 60 sidewalls 62 inner surface is provided with a plurality of fins 66, to constitute interference engagement together with respect to fan with projection, reach the purpose that cooperates with fan 20, sidewall 62 bottoms of each symmetrical sheet 60 bend inwards and form obliquely a clasp 68, are used for the groove 18 of buckle radiator 10.
