Abstract
The invention discloses a kind of lower resistance ventilating filter device, including ventilation door plate, formed with unit ventilators on ventilation door plate；In addition to the folding scape filter that is fixed on unit ventilators at the same time,；Shutter is fixed with the outside of folding scape filter；The draught area for the folding scape filter that lower resistance ventilating filter device uses is more than the three times of flat-panel filter, dust containing capacity increases into multiple, its flowing resistance only has less than the 1/3 of flat-plate drag, greatly reduces system ventilation resistance, increases the service life of filter.
Description
Technical field
The present invention relates to ventilation and heat technical field, more particularly to a kind of lower resistance ventilating filter device.
Background technology
In current cabinet design, especially wind electric converter, photovoltaic DC-to-AC converter, industrial frequency transformer industry, due to machine
Cabinet working site dust is more, if ventilating filter device design is improper, easily occurs two kinds extremely：One kind is extremely filter cotton
Too thick, flowing resistance is very big, causes rack cooling blower ventilation degradation, and rack is just offered a high price temperature after operation very short time
Failure；Another be extremely filter cotton it is too thin even without, directly result in rack external dust and enter interior of equipment cabinet, pollution electricity
Gas element, there are a series of device failure problems such as failure of insulation.
The content of the invention
It is an object of the invention to provide a kind of lower resistance ventilating filter device.
Therefore, technical solution of the present invention is as follows：
A kind of lower resistance ventilating filter device, including ventilation door plate, formed with unit ventilators on ventilation door plate；It is same with this
When, in addition to the folding scape filter being fixed on unit ventilators；Shutter is fixed with the outside of folding scape filter.
Preferably, in addition to it is arranged on the sealing strip at unit ventilators edge.
Preferably, described unit ventilators is the vent window array being made up of several vent windows.
Preferably, described folding scape filter includes metal frame and filter pulp；Consider cotton to be fixed on metal frame and by metal frame
It is completely covered, it is continuous " V " structure to consider cotton.
Preferably, described shutter is fixed by screws in the outside of ventilation door plate.
Compared with prior art, the draught area for the folding scape filter that the lower resistance ventilating filter device uses is flat board mistake
More than the three times of filter, dust containing capacity only has less than the 1/3 of flat-plate drag into multiple increase, its flowing resistance, greatly reduces system
System flowing resistance, increase the service life of filter；Second, folding scape filter and shutter combination, can be achieved vertically and horizontally
The water-proof function in direction；Third, folding scape filter and shutter are fixed, installation and replacing on the outside of door-plate by trip bolt
All it is to be carried out outside door-plate, in this embodiment it is not even necessary to shut down, easily maintain easily.
Brief description of the drawings
Fig. 1 is the structural representation of lower resistance ventilating filter device provided by the invention.
Fig. 2 is the structural representation of unit ventilators.
Fig. 3 is the section of structure of filter.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described further, but following embodiments are absolutely not to this hair
It is bright to have any restrictions.
Embodiment 1：
A kind of lower resistance ventilating filter device, including ventilation door plate 1, formed with unit ventilators on ventilation door plate 1；It is same with this
When, in addition to the folding scape filter 3 being fixed on unit ventilators；The outside of folding scape filter 3 is fixed with shutter 4；Also include
It is arranged on the sealing strip 2 at unit ventilators edge；Wherein, described unit ventilators is the vent window battle array being made up of several vent windows
Row.
The course of work of lower resistance ventilating filter device provided by the invention is as follows：
When the rack comprising ventilation door plate 1 operationally, the dust outside rack is kept off outside rack by folding scape filter 3, prevent
Only dust enters the electrical equipment in pollution rack in rack；At the same time, the shutter 4 being arranged on outside folding scape filter 3 can
Realize water-proof function both vertically as well as horizontally；When needing doubling scape filter 3 to be changed, carried out more directly outside door-plate
Change, it is not necessary to shut down, it is easy to operate.
Embodiment 2：
It is with the difference of embodiment 1：Described folding scape filter 3 includes metal frame 31 and filter pulp 32；Consider cotton 32
It is fixed on metal frame 31 and metal frame 31 is completely covered, it is continuous " V " structure to consider cotton 31；Described shutter 4 passes through
Screw is fixed on the outside of ventilation door plate 1.
The folding scape filter draught area is more than the three times of flat-panel filter, and into multiple increase, it is divulged information hinders dust containing capacity
Power only has less than the 1/3 of flat-plate drag, greatly reduces system ventilation resistance, increases the service life of filter.
