Description
Technical field
The present invention relates to electrical equipment technical field of heat dissipation, specifically, be related to one kind can free switching air-out direction
Air channel structure.
Background technology
The high-power inverter of photovoltaic industry or the mode of other electrical equipment generally use air blast coolings are radiated.
The forced air cooling Basic Design thinking is to set cooling system air inlet in the corresponding position of support body peripheral board, is learned according to heat is dynamic
Principle sets air outlet in enclosure top, then adds air channel to guide air draft in device external, device interior electric device is produced
Heat be discharged to device external.
Air-out mode is divided into " upper air-out " and " rear air-out " two ways substantially currently on the market, and upper air-out form easily will
More geothermal flows are taken away, but wind speed is slower, and rear air-out form goes out wind velocity faster, but the heat taken away is less, and radiating efficiency is low,
After each electrical equipment main frame structure determines, air-out form can only just select one kind in existing radiating mode, radiating effect
The drawbacks of rate is low is difficult to solve.
The content of the invention
The present invention is in order to solve the above problems, it is proposed that it is a kind of can free switching air-out direction air channel structure, the present invention
Fan chamber instead of air channel in itself, hence it is evident that save space, and realize " upper air-out " and " rear air-out " two kinds of structure shapes
The combination of formula, it is fast not only to go out wind velocity, and radiating efficiency is high, at the same changeable air-out mode cause product design and application all
It is more flexible.
To achieve these goals, the present invention adopts the following technical scheme that：
It is a kind of can free switching air-out to air channel structure, the air channel structure includes blower fan, blower fan fixed plate, air-ducting ring
And fan chamber, the blower fan are fixed in blower fan fixed plate, the blower fan fixed plate is fixed on the upper of the fan chamber
End, the air-ducting ring are connected with the lower end of the blower fan, and the blower fan is eccentric in fan chamber to be placed, the fan chamber
Upper surface and rear end face are removably provided with air outlet guard board and rear air outlet guard board respectively, and side is additionally provided with the fan chamber
Induced draft plate and wind deflector, the side induced draft plate and wind deflector will be rolled into the air channel of a scroll casing shape around blower fan, blower fan will be set
Standby interior heat pumping discharges heat to fan chamber, then by the upper air outlet guard board of fan chamber or rear air outlet guard board.
Further, the blower fan fixed plate is rectangle tabular structure, and the both ends of the blower fan fixed plate are inwardly curved
Folding forms flanging, and the blower fan fixed plate is fixed in the side wall of fan chamber by the flanging at its both ends, avoids because blower fan is transported
Row causes the vibration of fan chamber.
As a kind of preferable scheme, the blower fan is fixed by welding in the blower fan fixed plate, and the blower fan is consolidated
The flanging of fixed board is fixed by welding in the side wall of the fan chamber；
As another preferable scheme, the blower fan is fastened by bolts to fix in the blower fan and pulled, the blower fan
The flanging of fixed plate is fastened by bolts in the side wall of the fan chamber.
Further, the fan chamber is hollow rectangular-shape, and the side induced draft plate deviation is arranged on the wind
In the side wall of machine cavity room, the wind deflector at least two, the corner of fan chamber inwall is separately positioned on.
Further, the side induced draft plate surrounds cross section between three stage structure, with fan chamber and drawn to be trapezoidal
Wind region, air-out is prevented to be back to along blower fan convolution direction in the equipment enclosure that need to be radiated.
Further, the wind deflector is laminated structure, is arranged on the corner of the fan chamber inwall, surrounds transversal
Face is the wind-guiding region of triangle.
Further, the height of fan chamber lower end air intake space is not less than the height of fan chamber itself, in order to avoid
Can not air draft.
Further, the length and width size of the fan chamber must not avoid blower fan from damaging less than 1.4 times of blower fan diameter
The amount of going wrong, produce return air.
As a kind of preferable scheme, the air-ducting ring is the tubular structure that lower ending opening is big, upper end open is small, is easy to wind
The greater area of pumping hot blast of machine, improve pumping efficiency.
Further, the whole air channel structure is installed on the enclosure top for needing heat dissipation equipment, and fan chamber is used in itself
Substitute additional air channel.
Compared with prior art, beneficial effects of the present invention are：
(1) present invention realizes " upper air-out " and the combination of " rear air-out " two kinds of structure type, and it is fast not only to go out wind velocity, and
Radiating efficiency is high, while changeable air-out mode make it that the design of product and application are all more flexible.
(2) fan chamber of the invention instead of air channel in itself, hence it is evident that save space.

Example employs following technical scheme：
Following embodiments to embodiment describe in detail, and as shown in Figure 1, 2, one kind can free switching air-out
To air channel structure, the air channel structure includes blower fan 4, blower fan fixed plate 6, air-ducting ring 7 and fan chamber 1, the blower fan 4
It is fixed in blower fan fixed plate 6, the blower fan fixed plate 6 is fixed on the upper end of the fan chamber 1, the air-ducting ring 7 and institute
The lower end connection of blower fan 4 is stated, the blower fan 4 is eccentric in fan chamber 1 to be placed, the upper surface and rear end of the fan chamber 1
Face is removably provided with air outlet guard board 2 and rear air outlet guard board 8 respectively, be additionally provided with the fan chamber 1 side induced draft plate 3 and
Wind deflector 5, the side induced draft plate 3 and wind deflector 5 will be rolled into the air channel of a scroll casing shape around blower fan 4, blower fan 4 is by equipment
Interior heat pumping discharges heat to fan chamber 1, then by the upper air outlet guard board of fan chamber 1 or rear air outlet guard board.
The blower fan fixed plate 6 is rectangle tabular structure, and the both ends of the blower fan fixed plate 6 bend inwards to form folding
Side, the blower fan fixed plate 6 are fixed on by the flanging at its both ends in the side wall of fan chamber 1, so as to avoid because blower fan 4 is transported
Row causes the vibration of fan chamber 1, it should be noted that the height of the flanging must not be higher than the upper air outlet guard board 2.
In the present embodiment, the blower fan is fastened by bolts to fix in the blower fan and pulled, the blower fan fixed plate
Flanging is fastened by bolts in the side wall of the fan chamber.
The fan chamber 1 is hollow rectangular-shape, and what the side induced draft plate 3 was inclined to is arranged on the fan chamber 1
Side wall on, the wind deflector 5 at least two, be separately positioned on the corner of the inwall of fan chamber 1.
It is trapezoidal air inducing region that the side induced draft plate 3 surrounds cross section between three stage structure, with fan chamber 1,
Air-out is prevented to be back to along the convolution of blower fan 4 direction in the equipment enclosure that need to be radiated.
The wind deflector 5 is laminated structure, is arranged on the corner of the inwall of fan chamber 1, surrounds cross section as three
Angular wind-guiding region.
As shown in Fig. 3,4,5, blower fan 4 of the present invention is placed to be eccentric, and side induced draft plate 3 and wind deflector 5 around blower fan 4 wrapping
The air channel of " spiral case " shape is wrapped up in into, disclosure satisfy that the superposition of convolution air quantity, the mechanical path of tangential direction air-out, side induced draft plate
Effect be exactly allow air-out along convolution direction return.
As shown in Fig. 6,7 (a), 7 (b), 8, the height of the lower end air intake space of fan chamber 1 is not less than fan chamber 1
The height of itself, in order to avoid can not air draft.
