Abstract

The utility model relates to a combination of radiating devices. The utility model comprises a radiator and a pair of fastening pieces; the radiator comprises a base and a plurality of fins which are arranged on the top surface of the base, and opposite two ends of the base are respectively provided with a long flute which is used for embedding and positioning of the fastening pieces; each fastening device is provided with a horizontal butting section, the inner side of the butting section downwards extended to form a first extension piece, the end of the first extension piece is further reversely and upwards extended with a second extension piece, and a specific distance is spaced between the first extension piece and the second extension piece so that the first extension piece and the second extension piece are pressed to generate elastic deformation and can be correspondingly embedded into the flute of the base of the radiator; both ends of the butting section are respectively upwards inclined and extended to form an arm section, and the end of each arm section is downwards extended to form a buckling piece which is provided with a buckling hole.

Description

The heat abstractor combination

The utility model mainly is about the combination of a kind of heat abstractor, particularly makes up about a kind of heat abstractor that radiator and buckling piece can be combined in advance.

Existing heat abstractor combination for the central processing unit (CPU) heat transmission mainly comprises a radiator and some buckling pieces, wherein this buckling piece is made of a pressure section and the arm that extends obliquely respectively along these pressure section two ends, the end of each arm extends a snapping portion downwards, offer button hole in the snapping portion, by being clasped between the projection on button hole and the associated component, radiator can be fitted tightly to the central processing unit end face.But existing this kind heat abstractor combination, its buckling piece and radiator are separate type, are difficult to guarantee the correctness of relative position each other, therefore when being installed up to the heat abstractor composite entity on the associated component, need align buckling piece and radiator earlier, so then will increase the assembling degree of difficulty.In addition, this heat abstractor is combined in packing or transports in the process, and this buckling piece also needs and the radiator separate processes, and this apparent cost and efficient of being unfavorable for is considered.Related art in addition can be with reference to United States Patent (USP) the 5th, 602, and 719,5,600, No. the 85211135th, 85214941, No. 540 and Taiwan patent application etc.

The purpose of this utility model is to provide a kind of heat abstractor combination that radiator and buckling piece can be combined in advance.

The purpose of this utility model is achieved through the following technical solutions: the combination of the utility model heat abstractor mainly comprises a radiator and a pair of buckling piece.Wherein, this radiator comprises a pedestal and some fins of being located on this base top surface, and the opposite end portion of this pedestal is not provided with fin and directly exposes end face, and its position at contiguous fin offers a microscler groove.But this is positioned at the buckling piece inlay card on the both ends of radiator base, and each buckling piece has a horizontal pressure section, and the inboard of this pressure section is extended first Extendible flake down, and the end of first Extendible flake further oppositely extends second Extendible flake up.The junction of this first Extendible flake and second Extendible flake is the circular arc guiding face, and but the specific range of being separated by between first Extendible flake and second Extendible flake is so that both pressurized strains, and in the corresponding groove that embeds radiator base so that this buckling piece is fixed on the radiator.An arm is extended at the two ends of this pressure section respectively obliquely, and the end of each arm then extends a cramp downwards, offers a button hole on this cramp, is used for the projection on the framework of device radiation device with corresponding buckle.

Owing to adopted last technical scheme, the utlity model has that assembling is simple, advantage such as can effectively reduce cost.

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the three-dimensional exploded view of the utility model heat abstractor combination.

The three-dimensional combination figure of Fig. 2 the utility model heat abstractor combination.

The three-dimensional combination figure of combination of Fig. 3 the utility model heat abstractor and associated component.

Please refer to Fig. 1, the utility model heat abstractor combination 10 mainly comprises a radiator 12 and a pair of buckling piece 14.

This radiator 12 comprises a pedestal 20 and some fins of being located on these pedestal 20 end faces 22, and the opposite end portion of this pedestal 20 is not provided with fin 22 and directly exposes end face, and its position at contiguous fin 22 offers a microscler groove 24.

But this is positioned on the both ends of radiator 12 pedestals 20 buckling piece 14 inlay cards, each buckling piece 14 has a horizontal pressure section 40, the end that the inboard of this pressure section 40 is extended first Extendible flake, 42, the first Extendible flakes 42 down further oppositely extends second Extendible flake 44 up.The junction of this first Extendible flake 42 and second Extendible flake 44 is a circular arc guiding face 46, and but the specific range of being separated by between first Extendible flake 42 and second Extendible flake 44 is so that both pressurized strains, and in the corresponding groove 24 that embeds radiator 12 pedestals 20 so that this buckling piece 14 is fixed on the radiator 12.An arm 48 is extended at the two ends of this pressure section 40 respectively obliquely, and the end of each arm 48 then extends a cramp 50 downwards, offers a button hole 52 on this cramp 50, with framework 70 on projection 72 buckle (please refer to Fig. 3) mutually.

Please together with reference to figure 2, when on the both ends that this are embedded and located in radiator 12 pedestals 20 to buckling piece 14, the pressure section 40 of buckling piece 14 is fitted in pedestal 20 end faces of radiator 12, first Extendible flake 42 of buckling piece 14 and second Extendible flake 44 then pass through the guide function of circular arc guiding face 46, strain and in the corresponding groove 24 that embeds radiator 12 pedestals 20, so that this buckling piece 14 is fixed on the radiator 12.

Please together with reference to figure 3,, earlier central processing unit is installed on the connector 60 when this heat abstractor combination 10 and central processing unit (because of angular relationship can't be shown among the figure), when being installed in connector 60 on the circuit board 80 and framework 70 combinations.Then, on connector 60 both sides one framework 70 is set respectively, this framework 70 can directly be fixed on the circuit board 80 and roughly be the U font, the geomery that 70 one common peripheral of this two framework lay out cooperates with the pedestal 20 of radiator 12 and roughly is positioned at the outer rim of this pedestal 20, is respectively equipped with a projection 72 on the both ends of the surface of framework 70.Afterwards, heat abstractor combination 10 is placed on the central processing unit end face, and make that button hole 52 on 14 liang of cramps 50 of buckling piece is corresponding respectively accommodates the projection 72 that withholds framework 70 both ends of the surface and promptly finish assembling.
