In addition, all connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing connection auxiliary, Lai Zucheng more preferably connection structure.Each technology in the utility model is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
As shown in Figure 1, a kind of Switching Power Supply, including shell 100, circuit board 101, circuit board 101 are provided in shell 100
It is provided with several electronic components 102.
Conventional, Switching Power Supply narrow space, weak heat-dissipating, to solve this problem, conventional settling mode has plus heat dissipation
Piece and installation fan.
Commonly, in 101 upper opening of circuit board and fan is installed, also, is located at fan with electronic component 102
The same side of circuit board 101 reaches in turn and improves heat dissipation effect and avoid the problem that Switching Power Supply volume increases.
However, in fact, heat dissipation effect improvement is not obvious.Reason mainly has at 3 points:
First point, fan blowout it is distinguished and admirable to circuit board 101 backwards to several 102 sides of electronic component, that is to say, that
The wind of fan blowout is directly cooling to circuit board 101, then passes through the cooling electronic component 102 of circuit board 101, heat-conducting effect
Difference.
Second point, the wind of fan blowout be directly vertical impact shell 100 further along circuit board 101 and shell 100 it
Between gap flowing, the more kinetic energy of air loss, air flow resistance increases, and the power that needs to improve fan is mended
It repays, increases energy consumption.
Thirdly, the air near electronic component 102 is attracted at fan, and electronic component 102 has the work blocked
With the speed air flow near electronic component 102 is slower, reduces the heat exchanger effectiveness of electronic component 102 and air, leads
Cause the temperature of electronic component 102 high.
Therefore, solve the problems, such as that the radiating efficiency of Switching Power Supply is extremely urgent.
As shown in Fig. 2, to solve the heat dissipation problem of Switching Power Supply, the present embodiment makes to be provided with extension up and down in shell 100
Heat dissipation channel 500, circuit board 101 is set in heat dissipation channel 500, and circuit board 101 is set along the extending direction of heat dissipation channel 500
It sets.
The heat dissipation channel 500 that the present embodiment is extended up and down by setting, and make circuit board 101 along heat dissipation channel 500
Extending direction setting, thus, blower is set on circuit board 101 with routine and keeps blower generation vertical with circuit board 101
Air-flow is compared, can make air in heat dissipation channel 500 by with circuit board 101 it is approximately parallel in a manner of flow, thus, air can
It rapidly to flow through each electronic component 102, efficiently radiates to the electronic component of fever 102, it is ensured that electronics member
The temperature of device 102 belongs in controlled range；Moreover, air is flowed and is carried out to electronic component 102 cold along circuit board 101
But, compared with the conventional air-flow that blower is set on circuit board 101 and keeps blower generation vertical with circuit board 101, air stream
Dynamic direction transformation is few, and air flow resistance is small, can reduce the power of blower, reduces energy consumption；Furthermore due to mentioning for radiating efficiency
Height can select the electronic component 102 that heat resisting temperature is low, reduce cost.
