Technical field
The utility model belongs to electric-power filter field, and in particular to a kind of heat abstractor of wave filter.
Background technology
Active Power Filter-APF（APF：Active power filter）It is that one kind is used for dynamic harmonic wave, compensation nothing
The novel electric power electric device of work(, it can carry out quick tracing compensation to the harmonic wave of different size and frequency, why be referred to as
It is active, be relative to passive LC filter, can only be for the harmonic wave of Passive intake fixed frequency and size, APF can be by adopting
Sample load current simultaneously carries out each harmonic and idle separation, controls size, frequency and the phase of simultaneously active output current, and
Quick response, phase induced current in load is offset, realizes dynamic tracing compensation, and can not only mend harmonic wave but also mend idle and uneven
Weighing apparatus.
At present, wave filter its mainly include housing, electric elements and heat abstractor in housing, wherein in shell
The both sides of body are respectively equipped with air inlet and air outlet, and heat abstractor includes the fin between air inlet and air outlet, position
Fan at air outlet, wherein the setting by fan so that gas quickly flows, and then quick heat radiating.
However, when air-flow enters in the region of fin formation, fin contact face can produce certain to air-flow
Hinder, cause air-flow not flow smoothly, meanwhile, the dust in air is also easily accumulated in air inlet end, causes cleaning tired
Difficulty, in addition, the heat dissipation channel that most of fin are formed is straight, therefore, gas flow rate is too fast, cold and hot contact area and time
It is too short, cause heat exchange efficiency low.
The content of the invention
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided a kind of improved wave filter
Heat abstractor, it can not only cause hot and cold air fully to exchange on the premise of the smooth circulation of gas is ensured, and reduce
Heat dissipation region inlet end faces the obstruction of air-flow, prevents dust stratification, simple in construction, easy to implement, and cost is low.
To solve above technical problem, the utility model adopts the following technical scheme that：
A kind of heat abstractor of wave filter, it includes being arranged on fin, fan on electric elements, wherein fin position
Between the air inlet and air outlet of wave filter and including spaced body of multi-disc, wherein piece body from air inlet to
Air outlet continuously bends setting, and the gas channel formed between every two adjacent piece bodies is serpentine-like, and heat abstractor also includes
Gradually drawn close from two lateral middle parts of piece body formation gas channel and be arranged on shunting of the piece body close to the end of air inlet
Module.
Preferably, the downward orthographic projection of diverter module is trapezoidal or triangle.
According to one of the present utility model specific implementation and preferred aspect, the downward orthographic projection of diverter module is triangular in shape,
And drift angle of the triangle close to air inlet end is 10~60 °.
Preferably, drift angle of the triangle close to air inlet end is 30 °.Angle is excessive not to have drag-reduction effect, angle mistake
Small, self-strength is low, yielding.
Preferably, multiple diverter modules flush setting by the end of air inlet.
Preferably, multi-disc piece body flushes setting close to the end of air outlet.
Preferably, setting is flushed at the top of multi-disc piece body.
Entered according to another specific implementation of the present utility model and preferred aspect, fan including being separately positioned on gas channel
The blower fan and ventilating fan at mouthful and exit.By way of one inhales a row, gas is promoted smoothly to flow.
Preferably, there is the filter screen that dust in air can be removed between blower fan and air inlet.Prevent dust from entering
Enter, cause dust stratification.
In addition, the spacing between per adjacent two panels piece body is equal.So that flow is relatively uniform from gas channel
Flowing.
Due to the implementation of above technical scheme, the utility model has the following advantages that compared with prior art：
The utility model can not only cause hot and cold air fully to exchange on the premise of the smooth circulation of gas is ensured, and
And reduce the obstruction that heat dissipation region inlet end faces air-flow, and dust stratification is prevented, it is simple in construction, it is easy to implement, and cost is low.

Embodiment
Shown in Figure 1, according to the heat abstractor of the wave filter of the present embodiment, it includes being arranged on dissipating on electric elements
Backing 1, fan 2, wherein fin 1 are located between the air inlet a and air outlet b of wave filter, and spaced including multi-disc
Piece body 10, wherein piece body 10 continuously bend setting from air inlet a to air outlet b, between every two adjacent piece bodies 10
The gas channel c of formation is serpentine-like, and the two lateral middle parts that heat abstractor also includes being formed gas channel from piece body 10 are gradually leaned on
Hold together and be arranged on diverter module 3 of the piece body 10 close to the end of air inlet.
The downward orthographic projection of diverter module 3 is trapezoidal or triangle.It is triangle, therefore, windage now is most in this example
It is small, and will not dust stratification.
Specifically, drift angle of the triangle close to air inlet end is 10~60 °.
In this example, drift angle of the triangle close to air inlet end is 30 °.Angle is excessive not to have drag-reduction effect, angle mistake
Small, self-strength is low, yielding.
Multiple diverter modules 3 flush setting by air inlet a end.
Meanwhile multi-disc piece body 10 flushes setting close to air outlet b end.The top of multi-disc piece body 10, which also flushes, to be set
Put.
Fan 2 includes the blower fan 20 and ventilating fan 21 for being separately positioned on gas channel c entrances and exit.Pass through one
The mode of a row is inhaled, promotes gas smoothly to flow.
There is the filter screen 4 that dust in air can be removed between blower fan 20 and air inlet a.Prevent dust from entering,
Cause dust stratification.
In addition, in this example, the spacing between every adjacent two panels piece body 10 is equal.So that flow is relatively uniform from gas
Flowed in circulation road.
In summary, the present embodiment has the advantage that：
1st, the obstruction that heat dissipation region inlet end faces air-flow can be reduced so that gas flows more smoothly, is also prevented from
In air inlet end dust stratification；
2nd, the setting of serpentine flow path is passed through so that it is cold and hot fully to exchange and contact, and in the presence of one inhales a row,
Ensure heat exchange efficiency and effect.
