Description

Sink

[technical field]

The utility model is about a kind of sink, is meant especially a kind ofly can effectively improve radiating effect and in conjunction with firm sink.

[background technique]

Along with the computerized information industry develops rapidly, the arithmetic speed of all kinds of electrical assemblys is more and more faster, and the heat that it produced is also more and more, and if too much heat can't in time be discharged, the stability when having a strong impact on the electrical assembly operation.For this reason, industry is installed the sink combination of an aluminium extruding radiating fin and fan usually at the electrical assembly end face, to assist to discharge heat.

Existing sink comprises a fan 1 and a radiator 3 as shown in Figure 1.Four jiaos of ends of this fan 1 are respectively equipped with a fixed hole 2, this radiator 3 comprises a pedestal 4 and the radiating fin 5 some parallel to each other that is arranged on this pedestal 4, fixed hole 2 that should fan 1 attacked respectively between a pair of radiating fin 5 of this radiator 3 be provided with a tapped hole 6, pass the fixed hole 2 of this fan 1 and lock mutually and this fan 1 is fixed on this radiator 3 with tapped hole 6 on the radiating fin 5 of this radiator 3 by screw 7.But this fan 1 is the surface that is close to this radiator 3, makes the radiating airflow motion not smooth, thereby can influence radiating effect.In addition, the radiating fin 5 of this radiator 3 easily deforms under the extruding of screw 7, even there is this fan 1 to fix unstable doubt, therefore need the thickness of the radiating fin 5 of this radiator 3 of increase, and the thickness of radiating fin 5 increases, the integral heat sink surface area of radiator is reduced, and then influence radiating effect.

[summary of the invention]

The purpose of this utility model is to provide a kind of can effectively improve radiating effect and in conjunction with firm sink.

The purpose of this utility model is achieved through the following technical solutions: the utility model sink comprises a radiator, a fixing frame and a fan.Wherein, this radiator comprises a pedestal and the radiating fin some parallel to each other that is sticked on this pedestal, and the relative both sides of this base bottom surface are offered a flute profile fixing part respectively.The link arm that this fixing frame is provided with a roof and is extended vertically downward respectively by four jiaos of ends of this roof, this link arm can be fixed on the pedestal of this radiator, this edge, roof four corner bending downwards respectively extends a support plate, this support plate is used for being pressed on the radiating fin of this radiator so that form a gap between this fixing frame and this radiator, helps the circulation of air-flow; Each link arm inwardly is convexly equipped with a stopping plate respectively near the roof place, and this stopping plate block is in the relative both sides of radiating fin of this radiator, to prevent this fixing frame horizontal slip.This fan is fixed on the roof of this fixing frame.

Compared with prior art, the utility model sink has and can effectively improve radiating effect and in conjunction with firm advantage.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.

[embodiment]

Please consult Fig. 2 and Fig. 3 together, the utility model sink mainly comprises a radiator 10, a fixing frame 20 and a fan 40.

This radiator 10 comprises a pedestal 12 and the radiating fin 14 some parallel to each other that is sticked on this pedestal 12.Relative both sides, the bottom surface of this pedestal 12 are offered a flute profile fixing part 16 respectively, for the usefulness that is clasped; A groove 18 is offered at the end face middle part of this radiating fin 14, helps the circulation of air-flow.

The link arm 30 that this fixing frame 20 is provided with a roof 22 and is extended vertically downward respectively by 22 4 jiaos of ends of this roof.These roof 22 central authorities run through and offer a vent hole 24, its four corner is offered a fixed hole 26 respectively, each fixed hole 26 outside bends downwards respectively at the edge of roof 22 and extends a support plate 28, thereby this support plate 28 is pressed on the radiating fin 14 of this radiator 10 so that reserve certain clearance between this fixing frame 20 and this radiator 10, is beneficial to ventilate and make things convenient for the fixing of fan 40; The end of each link arm 30 further extends a button arm 32 downwards, in the flute profile fixing part 16 that is buckled in radiator 10 pedestals 12 bottom surfaces, and the place of each link arm 30 close roof 22 inwardly is convexly equipped with a stopping plate 34 respectively, thereby make the relative both sides of this stopping plate block when mounted, to prevent this fixing frame 20 horizontal slips at the radiating fin 14 of this radiator 10.

Four jiaos of end places of this fan 40 are respectively equipped with a perforation 42 to fixed hole 26 that should fixing frame 20 roofs 22, and are corresponding sealed and this fan 40 is fixed on this fixing frame 20 for some screw 50.

During assembling, in advance this fixing frame 20 is placed on the radiating fin 14 of this radiator 10, the support plate 28 of this fixing frame 20 is pressed on the radiating fin 14 of this radiator 10, and formation one space (not label) between this fixing frame 20 and this radiator 10, stopping plate 34 blocks of this fixing frame 20 are in the radiating fin 14 relative both sides of this radiator 10, button arm 32 by 20 4 jiaos of ends of this fixing frame bends inwards and this fixing frame 20 is fixed on this radiator 10 in the flute profile fixing part 16 that is buckled in these radiator 10 pedestals 12 bottom surfaces, this fan 40 is fixed on the roof 22 of this fixing frame 20 by screw 50 to get final product again.
