Description
Technical field
The utility model relates to the heat dissipation technology field of electronic devices and components, relates in particular to a kind of multidirectional tooth electronic radiation device.
Background technology
Power device is the Primary Component in most electronic equipments, and the quality of its operating state directly influences whole aircraft reliability.Especially high power device, its caloric value is big, only depends on the package casing heat radiation can't satisfy the heat radiation requirement; Need the rational radiator of configuration; Realize effectively heat radiation, and whether the selection of radiator rationally directly influences the reliability of power device so the factor of analyzing influence radiator heat-dissipation performance; Help rationally choosing radiator, improve the reliability of power device.
The geometry of Section Bar Heat Sinks is made up of fin and substrate; Main geometric parameters comprises that fin is long, fin is thick; Number of fins, substrate thickness, substrate width etc. have been studied the influence of Section Bar Heat Sinks geometrical factor to its hot property, through changing the geometric parameter of radiator; Can effectively reduce the thermal resistance of radiator, obtain good radiating effect.
When selecting radiator, generally need come choose reasonable according to heat radiator thermal resistance, also need consider simultaneously following some: the cost of space, air flow rate and radiator that radiator allows etc. is installed.The effect of radiator heat-dissipation and heat radiator thermal resistance big or small closely related; And the thermal resistance of radiator is except with radiator material is relevant; Also relevant with shape, size and the mounting means of radiator and environment ventilation condition etc.; Find that through experiment the geometrical factor of radiator has very big influence to the heat dispersion of radiator.
In changing each geometric parameter of radiator, do not change the geometric parameter of substrate, if because radiator leans on fin to increase the surface area of radiator, to reach efficiently radiates heat, substrate is also not obvious for the influence of radiator.And the size of change substrate difficult realization in engineering reality, also can make the radiator cost too high.Do not consider the size of radiator base plate during therefore general radiator optimal design.Comprehensive above data analysis can know that the thickness of radiator fins is obvious not as the influence of other geometric parameters of radiator to the influence of radiator performance.And the fin height is bigger than the influence of fin length to the radiator heat-dissipation Effect on Performance; The length, height and the thickness that suitably increase radiator fins can increase area of dissipation; Improve radiating effect; But when heat sink size arrives to a certain degree greatly, not obvious for the radiator heat-dissipation Effect on Performance, also can increase volume, weight and cost.Therefore, when carrying out the radiator optimal design, considered influences the principal element of radiator heat-dissipation performance, and the physical dimension of choose reasonable radiator is guaranteeing that little, the lightweight situation of radiator volume is issued to best radiating effect.
The utility model content
For solving the deficiency that exists in the prior art, the utility model provides a kind of heat-sinking capability strong multidirectional tooth electronic radiation device, and it is simple in structure, can effectively reduce manufacturing cost.
For realizing above-mentioned purpose; The multidirectional tooth electronic radiation device of the utility model; Comprise with the substrate of the thermal source part contact matching of electronic devices and components, be fixedly installed on the radiating fin group on the substrate; Described radiating fin group is made up of a plurality of fins, and each fin of forming the radiating fin group is multidirectional radial.
As the qualification to aforesaid way, described radiating fin group is the diffusion type that each fin radiation forms.
As the improvement to the utility model, described radiating fin group is two, and it is symmetricly set on the both sides of substrate.
Adopt technique scheme, multidirectional radial through fin is arranged to, can effectively improve radiating fin group and air contact area; Its maximum can improve 15%, and the performance of its radiator can improve 10%, simultaneously; This structure can not increase the size of substrate; Can be fit to electronic component dissimilar, model is dispelled the heat, it is simple in structure, and the cost of apparent wind cold heat sink declines to a great extent.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is the overall structure sketch map of the utility model.
Among the figure:
1, substrate; 2, radiating fin group; 3, fin; 31, trunk fin; 32, branch's fin.
Embodiment
Know by shown in Figure 1; The multidirectional tooth electronic radiation device of present embodiment; Comprise with the substrate 1 of the thermal source part contact matching of electronic devices and components, be fixedly installed on the radiating fin group 2 on the substrate 1; Radiating fin group 2 is made up of a plurality of fins 3, and each fin 3 of forming radiating fin group 2 is multidirectional radial.In the present embodiment, radiating fin group 2 is for being symmetricly set on two of substrate 1 both sides, the diffusion type that each fin 3 radiation of each radiating fin group 2 form; By finding out among the figure that the fin 3 of each radiating fin group 2 is divided into trunk fin 31 and branch's fin 32; Trunk fin 31 is connected with substrate 1, and with substrate 1 angled setting, each branch's fin 32 is connected with trunk fin 31; And with the 31 angled settings of trunk fin, each parts all adopts aluminum material to process.
As above structure in use; Substrate 1 thermal source with electronic component partly is connected, accepts the heat of thermal source by substrate 1, this heat passes to branch's fin 32 through the trunk fin 31 of radiating fin group 2; By trunk fin 31 and the heat exchange of branch's fin 32 common realizations with air; The setting of its structure can effectively increase the contact area of fin and air, and it is simple in structure.
In addition, what be worth explanation is, the quantity of each branch's fin 32 can increase or reduce according to actual conditions, and the angle between each branch's fin 32 and the trunk fin 31 also can be done corresponding adjustment, all belongs to the protection range of the utility model.
