Description

The heat abstractor combination

The utility model is about a kind of heat abstractor combination, particularly about a kind of heat abstractor simple in structure and easy to assembly, with low cost combination.

The heat abstractor combination of electronic component heat transmission commonly used mainly comprises radiator and fastener, it is after being attached to radiator on the electronic component end face earlier, utilize fastener and associated component or structure (the side projection of the connector that plugs for central processing unit for example again, the perhaps hole on the circuit board) hook between also is tight against radiator, and radiator is closely adhered on the electronic component.Wherein, this fastener is formed by metallic rod body bending, and this metallic rod body is to be positioned on the radiator by a clamping action that is fastened on the shell fragment in the radiator in addition.In this design, the arm that this metallic rod body has a horizontal pressure section and roughly oppositely vertical respectively bending is extended from these pressure section two ends, the end of each arm extends a fastener portion, by fastener portion and associated component or interstructural hook, just radiator is closely adhered on the electronic component end face; The section of this shell fragment is roughly V-shaped, and its bending zone clamps the pressure section of metallic rod body, and two terminal edge then are fastened on the radiating fin of radiator.But this design commonly used needs clamp earlier by a shell fragment in addition the pressure section of metallic rod body, and then this shell fragment and metallic rod body blocking together are positioned in the radiator, and therefore very complicated in the operation, inconvenience and cost are higher.Relevant common technology also can be with reference to United States Patent (USP) the 5th, 640, and 305,5,428, No. the 332721st, No. 897 and Taiwan patent announcement etc.

The purpose of this utility model is to provide a kind of simple in structure, easy accessibility, in conjunction with heat abstractor combination firm and with low cost.

For achieving the above object, the utility model has adopted following technical scheme: the combination of the utility model heat abstractor comprises a radiator and a fastener.This radiator is formed by a pedestal and from a plurality of radiating fins of this base top surface vertical extent and parallel interval arrangement, and each is arranged and all forms a groove between radiating fin, and equal correspondence protrudes out a stop section on the radiating fin internal face of middle groove both sides.This fastener is to be placed in the groove of this radiator, its by a metallic rod body continuously bending form, mainly comprise a location division and two pressure sections that are used for the corresponding butt in stop section of this radiator.This location division comprises one first kink and two second kinks, all be by the central authorities of this fastener continuously bending form and all be the shape of falling U, wherein this two second kink by the first kink two ends respectively outwards bending extend and to form, and have with respect to this first kink and to be used for the suitable angle of stop section of this radiator of elasticity butt; This two pressure section is extended by the two ends, location division respectively, and the vertical respectively in the opposite direction bending of the end of each pressure section extends an elastic arm, and the end of each elastic arm forms a clasp.

Compared with prior art, the utility model heat abstractor combination directly elasticity butt between the stop section of the location division by fastener and radiator realizes entire combination, so has advantages such as simple in structure, easy to assembly and with low cost.

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

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

Fig. 2 is the stereogram of the fastener of the utility model heat abstractor combination.

Fig. 3 is the end view of the utility model heat abstractor combination.

Fig. 4 is the three-dimensional combination figure of combination of the utility model heat abstractor and associated component.

Please together consult Fig. 1 to Fig. 4, the combination of the utility model heat abstractor comprises a radiator 20 and a fastener 30.This fastener 30 is installed on this radiator 20, and can combine with a circuit board 50 (also can be other assembly) and this radiator 20 be closely adhered on the electronic component 60, wherein this electronic component 60 is installed on the circuit board 50, and this circuit board 50 is respectively equipped with a button hole 51 in the diagonally opposing corner outside of electronic component 60.

This radiator 20 is formed by a pedestal 21 and from a plurality of radiating fins 23 of these pedestal 21 end faces, 22 vertical extent and parallel interval arrangement, each is arranged 23 of radiating fins and all forms a groove 25, and equal correspondence protrudes out a stop section 24 on the internal face of the radiating fin 23 of middle groove 25 both sides.

This fastener 30 is bent continuously by an elastic metallic body of rod and forms, mainly comprise a location division 31 and two pressure sections 37, wherein this location division 31 is positioned at the central authorities of this fastener 30, itself and the stop section 24 corresponding butts of this radiator 20, and this pressure section 37 is compressed on the end face 22 of this radiator 20.This location division 31 comprises one first kink 34 and two second kinks 32,36, all be by the central authorities of this fastener 30 continuously bending form and all be the shape of falling U, this two second kink the 32, the 36th wherein, by first kink, 34 two ends respectively outwards bending extend and to form, and has suitable angle (please refer to Fig. 3) with respect to this first kink 34, for the stop section 24 that this radiator 20 can elastic shrinkage be crossed in the location division 31 of this fastener 30, elastic recovery is tight against this stop section 24 and fastener 30 is stabilized in the groove 25 of this radiator 20 then.This two pressure section 37 is extended by these 31 two ends, location division respectively, and the end of each pressure section 37 in the opposite direction respectively bending extend an elastic arm 38, the end of each elastic arm 38 is bent to form a clasp 39 that is used for the button hole 51 corresponding snappings of circuit board 50.

During assembling, this fastener 30 is placed in the middle groove 25 of this radiator 20 and presses down this fastener 30, the angle of 32,36 of first kink 34 of fastener 30 and second kinks is diminished, and the stop section 24 that makes the location division 31 of this fastener 30 cross this radiator 20.Then, three kinks, 32,34,36 elastic recoverys of these fastener 30 location divisions 31 are tight against on the stop section 24 of this radiator 20 to first leading angle, and simultaneously, two pressure sections 37 of this fastener 30 are connected on the end face 22 of this radiator 20.At last, again the combination of this heat abstractor is placed on the end face of electronic component 60, and two elastic arms 38 that press down this fastener 30 move down this two clasp 39 and corresponding being fastened in two button holes 51 of this circuit board 50, promptly finish assembling.
