Abstract
The utility model relates to a frequency-variable speed adjuster of a separated cooled air flue, which is particularly to suitable for industry with poor operational environment, such as textile industry and chemical fiber industry. On the installing structure of the entire frequency-variable speed adjuster, a heat dissipation air flue is separated from a driving board a main control board, and the processing of sealing and mounting is carried out to the driving board and the main control board; a module and a heat dissipator are installed in an independent cooled air flue for forcing wind cooling and heat dissipation through a fan. The frequency-variable speed adjuster with the structure can dissipate heat normally, and can make the main control board and the driving board be free of the corrosion and piling of oil solutions, fabric fly and dust in the using process in the environment of the textile industry and the chemical fiber industry; the stability and the reliability of the frequency-variable speed adjuster are enhanced.
Description
Affiliated technical field
The utility model relates to a kind of variable-frequency governor of design isolated formula cooling air channel, especially is applicable to the variable-frequency governor that uses under the industry environment poor condition such as chemical fibre, weaving.
Background technology
At present, known variable-frequency governor is installed in radiator, power model, drive plate, master control borad in the same shell, and by fan frequency converter is dispelled the heat.When being applied to the bad industries of environment such as chemical fibre, weaving, circulation along with the air blast cooling air, airborne harmful finish has caused extremely strong corrosivity to electronic circuit board, cause that frequency converter failure increases, the shortening in useful life, although taked the method that applies, kept away unavoidable finish and slowly invade; And flyings accumulation in the heat radiation process causes heat radiation and insulation function to descend in the circuit board in the textile industry, and these all are unfavorable for the smooth production of enterprise very much, cause great hidden danger for the production of chemical fibre, textile industry.
Summary of the invention
Break down and have a strong impact on production in order to overcome the variable-frequency governor frequency converter that electronic circuit board is produced by flyings dust accumulation by the finish burn in chemical fibre, textile industry use.The utility model provides a kind of new variable-frequency governor, and this frequency converter not only heat dissipation ventilation is respond well, and has avoided the bad phenomenon to the accumulation of electronic circuit board finish burn into flyings effectively.
The technical scheme that this suitable novel its technical problem of solution is adopted is: on the mounting structure of the inside of frequency converter, with an interlayer board frequency converter inner space on average is divided into two, top (ribbon gymnastics is made the part of panel) installs drive plate, master control borad; The bottom then constitutes cooling air channel, generally is a cuboid passage, and an end is that the fan air-out is installed, the other end is an air inlet, all the other four sides are respectively housing and interlayer board, and module, radiator are installed in the cooling air channel, isolated cooling air channel forms, with radiator, module and drive plate.Master control borad is isolated installation, and heating own is not very high during the work of electronic circuit boards such as drive plate, master control borad, with its encapsulation process, is not subjected to the contact of outside air; And module, radiator are installed in the independent ventiduct, and by fan air blast cooling heat radiation, wind directly enters radiator from the air channel air inlet, behind fan, discharge, the heating of frequency converter complete machine has just obtained effective control like this, and finish, dust, flyings are piled up the burn into of electronic circuit board and also are resolved the corresponding minimizing of the fault of frequency converter fully, enterprise's production stability is improved
The beneficial effects of the utility model are, can avoid finish, weaving flyings, dust that the burn into of electronic circuit board is piled up under environment such as chemical fibre, weaving and influences the function of use of variable-frequency governor, and structure is changed and simply, more become reasonable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Accompanying drawing is the inner mounting structure schematic diagram of the utility model variable-frequency governor
Among the figure: 1 guidance panel, 5 inversion modules, 9 fans
2 master control borads, 6 radiators, 10 air intakes
11 air-out of 3 drive plates, 7 interlayer boards
4 rectification modules 8 are installed bottom outlet
Embodiment
In the accompanying drawings, by 7 interlayer boards with the frequency converter inner space standardized be that two, 2 master control borads, 3 drive plates and 4 rectification modules, 5 inversion modules, 6 radiators are kept apart fully.2.3. be installed in the top of relative isolation sealing, 4,5,6 are installed in the bottom, the bottom constitutes cooling air channel simultaneously.After bottom outlets being installed frequency converter is installed by 8, along with the running of 9 fans, cooling air enters cooling air channel from air inlet 10,6 radiators is dispelled the heat, and heat is discharged from 11 air outlets through 9 fans; The finish that exists in the air ambient, weaving flyings, dust from the cooling air channel turnover, do not have influence to 2 master control borads, 3 drive plates simultaneously substantially, reach purpose of design.
Claims (2)
1, the utility model is a kind of variable-frequency governor of isolated cooling air channel, it is characterized in that: on the mounting structure of each parts of frequency converter, with heat dissipation wind channel and drive plate, master control borad is isolated is installed separately.
2, variable-frequency governor according to claim 1, it is characterized in that: frequency converter is separated with an interlayer board, master control borad, drive plate are installed in top, rectification module, inversion module, radiator are installed in the bottom, the bottom constitutes cooling air channel simultaneously, fan by top is forced to carry out air-cooled, reaches cooling effect.
