Abstract

The utility model discloses a beveled opening type electronic heat dissipation device. The beveled opening type electronic heat dissipation device comprises a heat dissipation substrate, and a plurality of heat dissipation fin groups located on the top of the heat dissipation substrate. Each heat dissipation fin group is composed of more than two heat dissipation fins, and the air inlet end face of each heat dissipation fin group is an inclined surface. According to the beveled opening type electronic heat dissipation device provided in the utility model, not only advantages of intensive heat dissipation fin distribution and high heat dissipation power are retained, but also the problem of large air resistance is solved. Compared with existing heat dissipation devices, the beveled opening type electronic heat dissipation device of the utility model can be used to achieve a same heat dissipation effect with advantages of low cost, light weight, reduced consumption of raw materials and reduced consumption of industrial energy resources.

Description

Inclined mouth type electronic radiation device
Technical field
The utility model relates to a kind of electronic radiation device, relates in particular to a kind of inclined mouth type electronic radiation device, belongs to technical field of electronic equipment.
Background technology
Development along with the electronic component high-frequency high-speed; The heat that electronic component produced is also more and more; The working temperature of electronic component constantly raises, and has had a strong impact on the useful life and the operation stability of each element, so must carry out radiating treatment to the electronic component in the work.The common air-cooled radiator of existing market has a large amount of, intensive radiating fin usually, and what fin was neat is arranged on the heat-radiating substrate, and in specific air channel, there is non-uniform phenomenon in the fin surface air velocity that area is bigger, and the zone that flow velocity is big helps heat radiation.And adjacent two radiating fin spacings are less, and retaining space is few, all can form certain turbulent flow around each radiating fin, cause windage to become big, and the windage conference reduces radiating fin surrounding air amount of flow, influences radiating effect.And this kind heatsink mass is big, expensive.
The utility model content
The technical problem that the utility model will solve provides a kind of inclined mouth type electronic radiation device, and it had both kept the radiating fin dense distribution, and the advantage that heat radiation power is big has solved the big problem of windage again.Low, the light weight of its cost, conservation and industrial energy consumption under the identical radiating effect.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of inclined mouth type electronic radiation device comprises heat-radiating substrate and a plurality of radiating fin groups that are positioned at the heat-radiating substrate top, and said radiating fin group is made up of plural radiating fin, and the air intake end face of said radiating fin group is the inclined-plane.
As the improvement to the utility model, the air intake end face of said adjacent two radiating fin groups is oppositely arranged.
Another kind as to the utility model improves, and said radiating fin inside is provided with the air channel that connects radiating fin.
As the third improvement to the utility model, said radiating fin internal fixation is provided with the dividing plate that the air channel is cut apart.
The utility model also has a kind of improvement, and said radiating fin group and heat-radiating substrate clamping connect firmly.
Owing to adopted technique scheme, the utility model compared with prior art, the technological progress that is obtained is:
1, the structure of heat dissipation substrate of integral type can effectively distribute the bottom heat rapidly, makes heat in time, effectively pass on the radiating fin, thereby improves integral heat sink usefulness.Because storeroom is seamless link, the inner heat conduction of radiator is even, thermal conductivity is high.Compare with the radiator of same size, same material, same profile, its thermal resistance is minimum.
2, the end face of the air intake of radiating fin adopts the inclined-plane form, makes wind direction be able to the side direction drainage, reduces the influence of positive windage, makes thermal resistance descend 20%; Solved windage homogenizing problem, avoided leaving big spatial domain and influencing electronic component integral heat sink effect along air channel.
3, can adjust the spacing of quantity, angle of inclination and adjacent two radiating fins of radiating fin according to heat-radiating substrate size, shape, heat radiation power consumption.
The utlity model has low, the light weight of cost, the characteristics that conservation and industrial energy consume had both kept the radiating fin dense distribution, and the advantage that heat radiation power is big has solved the big problem of windage again, is applicable to the large power, electrically sub-element of air blast cooling.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Fig. 1 is this practical new embodiment overall structure sketch map;
Fig. 2 is that the position of single radiating fin group concerns sketch map.
Among the figure: 1, heat-radiating substrate; 2, radiating fin group; 3, air channel; 4, dividing plate.
Embodiment
Shown in Figure 1 is a kind of inclined mouth type electronic radiation device, comprises heat-radiating substrate 1 and a plurality of radiating fin groups 2 that are positioned at heat-radiating substrate 1 top.Radiating fin group 2 is formed (as shown in Figure 2) by two radiating fins.The material of heat-radiating substrate 1 and radiating fin group 2 is aluminium section bar or aluminium sheet, and the two can be according to heat spreader structures demand adjustment length and width
Heat-radiating substrate 1 top is provided with groove, and radiating fin group 2 bottoms are installed in the groove.
The air intake end face of radiating fin group 2 is the inclined-plane, and the air intake end face of adjacent two radiating fin groups 2 is oppositely arranged, and makes wind direction be able to the side direction drainage, reduces the influence of positive windage, reduces thermal resistance.
Radiating fin inside is provided with the air channel 3 that connects radiating fin.The radiating fin middle part is provided with dividing plate 4, and air channel 3 is divided into upper and lower two parts.Air channel 3 be beneficial to control in the heat transfer process distinguished and admirable to.
Radiating fin group 2 can be come the spacing of quantity, angle of inclination and adjacent two radiating fin groups 2 according to size, shape, the heat radiation power consumption of heat-radiating substrate 1.
In the present embodiment, the width of radiation tooth and quantity design are more flexible, and its area of dissipation is greater than Section Bar Heat Sinks under the equal volume.
