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.
In existing radiating subassembly, heat dissipation wind channel part also includes heat dissipation wind channel 11 and is formed in heat dissipation wind channel 11 substantially
First end air inlet 12, and be formed in the air outlet 13 of the second end of heat dissipation wind channel 11.It can be arranged at air inlet 12
One big fan imports air-flow, and a small fan export air-flow can be arranged at air outlet 13.
It finds after study, when heat dissipation wind channel 11 is larger, small fan forms vacuum effect deficiency, and it is suitable also to will affect air-flow
Channel Group is logical.At this moment, big fan air-flow is too strong, and preposition small fan flow velocity is too low, and the air quantity poured in from entrance is exported greater than small fan
Air quantity, the presence of small fan also partial occlusion exhaust outlet influences airflow smooth circulation, causes the whole gas velocity to spend slowly,
Influence overall heat exchange.
Based on the above issues, in the technical solution of the utility model, small fan is cancelled, also increases air outlet, is made
Air outlet is more convenient for air draft.As shown in Figure 1, in the technical solution of embodiment one, radiating subassembly include heat dissipation wind channel part and
Fan part 20, heat dissipation wind channel part are used to treat the element radiating of heat dissipation.Heat dissipation wind channel part includes heat dissipation wind channel 11 and is formed in
The air inlet 12 of the first end of heat dissipation wind channel 11, and it is formed in the air outlet 13 of the second end of heat dissipation wind channel 11, air outlet 13
Form opposite outwardly extending first flaring structure of heat dissipation wind channel 11.Fan part 20 is correspondingly arranged with air inlet 12, for into
It divulges information in air port 12.
Using the technical solution of the utility model, the fan being arranged at air outlet 13 is eliminated, only sets fan part 20
It sets in position corresponding with air inlet 12, reduces and go out wind resistance at air outlet 13.Meanwhile also by air outlet 13 formed to
First flaring structure of outer extension reduces by 13 inner wall of air outlet for air-flow so that air-flow is more convenient for being discharged from air outlet 13
Resistance, so that heat dissipation wind velocity lift, and then improve radiating efficiency.
As a preferred embodiment, as shown in Figure 1, air inlet 12 to form opposite heat dissipation wind channel 11 outwardly extending
Second flaring structure.Since the wind of the first fan part 20 blowout can have expansion trend with the flowing of air-flow, and 11 shape of air inlet
At flaring structure be then conducive to gather the air-flow of the first fan part 20 blowout, prevent air-flow from being formed in corner and be vortexed and stop.
In addition, according to continuity equation in hydrodynamics, the area of the air intake surface of air inlet 11 is since air inlet 11 is flaring structure
V1, wind speed A1, the area of the outlet air surface of air inlet 11 is V2, wind speed A2, i.e. V1A1=V2A2, due to area A1 > A2, then
It will lead to V1 < V2.I.e. when the first fan part 20 blows to the air intake surface of air inlet 11, speed is smaller, after air inlet 11, just
Meeting improves radiating efficiency so that wind velocity lift.
Optionally, in the technical solution of embodiment one, radiating subassembly further includes radiating fin, for being arranged wait radiate
Element on, heat dissipation wind channel part be arranged on radiating fin.Heat dissipation wind channel can be cooperated by radiating fin with increasing heat radiation area
