Abstract
The utility model provides a radiating device, comprising at least a radiator and a fan. The radiator comprises a plurality of radiation fins, the fan is fixed on the radiator, and an element for vibration reduction and acoustical absorption is arranged between the fan and the radiation fins of the radiator. The radiation device of the utility model on one hand damps vibration when the fan operates not to go so far as to convey to the radiator causing vibration of the thinner radiation fins and on the other hand the element for vibration reduction and acoustical absorption presses the thinner radiation fins enabling the element for vibration reduction and acoustical absorption not to generate resonance to send out great noise under the wind pressure.
Description
[technical field]
The utility model is meant a kind of radiator of electronic element radiating and composite set of fan of being used for especially about a kind of heat abstractor.
[background technology]
Along with developing rapidly of electronic information industry, the speed of service of electronic component constantly promotes, the heat of its generation also increases thereupon, if untimely heat with its generation is discharged, to cause its temperature constantly to raise, and then have a strong impact on the performance of its operation, can normally move for guaranteeing electronic component, usually at its mounted on surface one heat abstractor so that heat is distributed apace.
Heat abstractor generally comprises radiator and fan two parts, have some radiating fins on the radiator, fan is fixed on the radiator so that the forced convertion air to be provided, and fan on the one hand because various unpredictable factors are not steady as installation, or uses the back influence of factors such as becoming flexible to occur in running for a long time, to produce vibration, simultaneously because directly the rigidly fixing of fan and radiator, will drive radiator and the radiating fin that especially approaches vibrates together, send bigger noise; On the other hand, under the blast of fan, thin radiating fin also resonates easily.
[summary of the invention]
The purpose of this utility model is to provide a kind of heat abstractor with vibration and noise reducing function.
The purpose of this utility model is achieved through the following technical solutions: the utility model heat abstractor, at least comprise a radiator and a fan, this radiator comprises some radiating fins, this fan is fixed on this radiator, is provided with the vibration damping sound-absorbing element between the radiating fin of this fan and this radiator.
Compared with prior art, the utility model is by being provided with the vibration damping sound-absorbing element between the radiating fin of fan and radiator, and the vibration that produces when buffering weakens fan running on the one hand makes its unlikely radiator that is passed to make thin radiating fin vibration; On the other hand, this vibration damping sound-absorbing element is pushed down thin radiating fin, makes radiating fin can not produce resonance under the blast of fan, unlikely generation noise, and this vibration damping sound-absorbing element also has certain sound absorption, the noise that produces when absorbing the work of fan and other element.
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the utility model heat abstractor.
Fig. 2 is the combination front view of Fig. 1.
[embodiment]
See also Fig. 1, the utility model heat abstractor comprises a fan 10, a fan Fixture 20, a vibration damping sound-absorbing element 30 and a radiator 40.
The corner location of these fan 10 housings 11 respectively has a through hole 12.
This fan Fixture 20 is used for fixing this fan 10, its nearly corner location has the screw 22 corresponding with the through hole 12 of fan 10, fan 10 is fixed on this fan Fixture 20 as screw etc. for plurality of fixed part 13, but is extended with the clasp 24 of hook under four angles of fan Fixture 20 in radiator 40 bottom surfaces.
This vibration damping sound-absorbing element 30 is a hollow annular structure, and its material is for having the vibration damping sound absorption function and have better flexible foam or rubber, as the acoustical cotton sold on the market, shock-reducing rubber etc.
This radiator 40 comprises a pedestal 42 and the some radiating fins that are parallel to each other 44 that are positioned on the pedestal 42, this radiating fin 44 is converted into wavy by a sheet metal Curved Continuous, the bottom surface of substrate 42 is provided with the fluting 46 that matches with the clasp 24 of fan Fixture 20.
See also Fig. 2, during assembling, by fixture 13 and through hole 12 and cooperating of screw 22 and fan 10 is fixed on the fan Fixture 20, vibration damping sound-absorbing element 30 is arranged at the end face of the radiating fin 44 of radiator 40, the fan Fixture 20 that is fixed with fan 10 is placed on the vibration damping sound-absorbing element 30, again with clasp 24 hooks of fan Fixture 20 in the fluting 46 of substrate 42 bottom surfaces of radiator 40 and fan Fixture 20 and fan 10 are fixed in radiator 40 tops, thereby vibration damping sound-absorbing element 30 is fixed between the radiating fin 44 of fan Fixture 20 and radiator 40.
In the utility model heat abstractor, by between fan Fixture 20 and radiating fin 44, vibration damping sound-absorbing element 30 being set, the vibration that produces when making on the one hand fan 10 runnings weakened and absorbs through vibration damping sound-absorbing element 30 elastic buffers before being delivered to radiator 40, and unlikely being delivered to causes on the radiator 40 that the radiating fin 44 that approaches follows vibration; On the other hand, this vibration damping sound-absorbing element 30 is pushed down thin radiating fin 44, radiating fin 44 is fused and increases resistance capacity to deformation, can not produce resonance under the blast of fan 10, causes to cause noise; In addition, this vibration damping sound-absorbing element 30 has certain sound absorption, the noise that produces when absorbing the work of fan 10 and other element.
This vibration damping sound-absorbing element 30 is not limited to ring-type, can cut into other shape such as bulk etc. according to actual needs.
In the foregoing description, because radiating fin 44 is thinner, for preventing that directly screw lock fixture 13 deforms it thereon, thereby used fan Fixture 20, certainly, fan 10 also can directly be fixed on by alternate manner on the radiator 40, for example, when the radiating fin for locking fixture 13 has enough thickness, also can fan 10 be locked on this radiating fin by fixture 13, at this moment vibration damping sound-absorbing element 30 is set between fan 10 and radiating fin.
