Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached
Figure, is described in further details the utility model.Here, the exemplary embodiment and its explanation of the utility model are for solving
The utility model is released, but is not intended to limit the scope of the present invention.
Fig. 1 shows the embodiment one of the radiating subassembly of the utility model, which includes 10 He of heat dissipation wind channel part
First fan part 20, heat dissipation wind channel part 10 are used to treat the element radiating of heat dissipation.Heat dissipation wind channel part 10 includes air duct 13 and shape
At the air inlet 11 of the first end in air duct 13, and it is formed in the air outlet 12 of the second end in air duct 13, the formation of air inlet 11
The opposite outwardly extending flaring structure in air duct 13.First fan part 20 is correspondingly arranged with air inlet 11, for logical to air inlet 11
Wind.
Using the technical solution of the utility model, the wind of the first fan part 20 blowout can have expansion to become with the flowing of air-flow
Gesture, and the flaring structure that air inlet 11 is formed then gathers the air-flow of the first fan part 20 blowout.In addition, since air inlet 11 is to expand
Mouth structure, according to continuity equation in hydrodynamics, the area of the air intake surface of air inlet 11 is V1, wind speed A1, air inlet 11
Outlet air surface area be V2, wind speed A2, i.e. V1A1=V2A2 due to area A1>A2 then will lead to V1<V2.I.e. first
When fan part 20 blows to the air intake surface of air inlet 11, speed is smaller, after air inlet 11, will make wind velocity lift, in turn
So that heat dissipation wind speed is greatly improved, radiating efficiency is improved.
As a kind of more preferably embodiment, as shown in Figure 1, in the technical solution of embodiment one, radiating subassembly
It further include the second fan 30, the second fan 30 is correspondingly arranged with air outlet 12, is used for from the outside exhausting of air outlet 12.Pass through second
Fan 30 can drain the gas in air duct 13 from the outside exhausting of air outlet 12 as early as possible, so that air duct 13 is in negative pressure state, into
And can more preferably be entered the wind by air inlet 11, air circulation efficiency is improved, and then improve radiating efficiency.
During actual use, the air inlet 11 of flaring structure is beneficial for air inlet.But if air outlet 12
Opening it is big, the gap that will lead between the second fan 30 and air outlet 12 is excessive, and then leads to the suction of the second fan 30
Power can not be applied to completely on air duct 13, and the effect of the second fan 30 is caused to reduce.In order to solve the technical problem, in embodiment
One technical solution, air outlet 12 form the opposite outwardly extending throat structure in air duct 13.By the way that air outlet 12 is set as contracting
Mouth structure can allow the outlet air surface of air outlet 12 to reduce, and then reduce the gap of the second fan 30 and air outlet 12, guarantee second
The effect of fan 30.
