Description

A kind of magnetic suspension cfentrifugal blower cabinet
Technical field:
The present invention relates to a kind of magnetic suspension cfentrifugal blower cabinets.
Background technique:
Existing magnetic suspension cfentrifugal blower mostly uses greatly the structure of the system integrations such as host, automatically controlled, cooling, but certain Under operating condition, when needing more Fans centralized controls, concentrating cooling, need to separate a system.
Existing structure is unfavorable for centralized control, is unfavorable for concentrating cooling, air inlet flow resistance is big, noise is big, when more operations The space occupied is big.
Summary of the invention:
The present invention is to provide a kind of magnetic suspension cfentrifugal blower machine to solve the above-mentioned problems of the prior art Cabinet.
The technical solution adopted in the present invention has: a kind of magnetic suspension cfentrifugal blower cabinet, including cabinet and magnetic suspension Blower, the magnetic suspension blower are placed in cabinet, and cabinet is rectangular structure, are equipped with air inlet on four sides of cabinet Mouthful, it is equipped with coolant flow channel on magnetic suspension blower, further includes soundproof plate, several soundproof plates are along air intake duct in magnetic suspension blower Circumferencial direction be uniformly distributed, and form silencing cavity between adjacent two soundproof plate, silencing cavity is connected with air inlet, soundproof plate Both ends are fixed in cabinet;
Forceful electric power connection jaws, light current connection jaws, rotor cooling wind interface and stator cooling water interface are equipped on cabinet, it is described Rotor cooling wind interface connects a root canal road, which stretches in the bottom end of magnetic suspension blower, connect on stator cooling water interface Water pipe, water pipe are connected with the coolant flow channel on magnetic suspension blower;The outer wall of the cabinet is equipped with air outlet.
Further, the soundproof plate is convex structure, including Inner arc orifice plate, external arc orifice plate, intermediate silencing cotton And end plate, the Inner arc orifice plate and external arc orifice plate are arranged in parallel, and shape between Inner arc orifice plate and external arc orifice plate At filling gap, intermediate silencing cotton is filled in the filling gap, and end plate is fixed on the surrounding of inside and outside circular arc orifice plate and will fill out Fill gap closing.
Further, it is fixedly connected with connection sheet on the outer wall of the soundproof plate, fixation hole is equipped in connection sheet.
Further, the air inlet is equipped with strainer.
The invention has the following beneficial effects: the present invention to be equipped with individual stator cooling water, rotor cooling wind interface, can be real Now more concentration coolings;The external interface of individual forceful electric power and light current is, it can be achieved that more centralized controls;The radial of air inlet disappears Sound structure, can reduce air inlet flow resistance reduces the noise of blower.Due to being to concentrate cooling and centralized control, more run when institute simultaneously It takes up space smaller than original structure.
Detailed description of the invention:
Fig. 1 is structure of the invention figure.
Fig. 2 is structure of the invention figure.
Fig. 3 is the structure chart of soundproof plate in the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1 to Fig. 3, a kind of magnetic suspension cfentrifugal blower cabinet of the present invention, including cabinet 1, magnetic suspension blower 2 and every Soundboard 3, magnetic suspension blower 2 are placed in cabinet 1, and cabinet 1 is rectangular structure, are equipped with air inlet on four sides of cabinet 1 Mouth 11, several soundproof plates 3 are uniformly distributed along the circumferencial direction of air intake duct 21 in magnetic suspension blower 2, and adjacent two soundproof plate 3 Between form silencing cavity 30, silencing cavity 30 is connected with air inlet 11.The both ends of soundproof plate 3 are fixed in cabinet 1, soundproof plate 3 Positioned at the inside of air inlet 11.
Forceful electric power connection jaws 4, light current connection jaws 5, rotor cooling wind interface 6 and stator cooling water interface are equipped on cabinet 1 7, rotor cooling wind interface 6 connects a root canal road, which stretches in the bottom end of magnetic suspension blower 2, on stator cooling water interface 7 Water pipe is connected, water pipe is connected with the coolant flow channel on magnetic suspension blower 2.
Soundproof plate 3 is convex structure, including Inner arc orifice plate 31, external arc orifice plate 32, intermediate silencing cotton 33 and end plate, Inner arc orifice plate 31 and external arc orifice plate 32 are arranged in parallel, and are formed and filled out between Inner arc orifice plate 31 and external arc orifice plate 32 Gap is filled, intermediate silencing cotton 33 is filled in the filling gap, and end plate is fixed on the surrounding of inside and outside circular arc orifice plate and will filling Gap closing.
For the fixed installation convenient for soundproof plate 3, connection sheet 34 is fixedly connected on the end plate of bottom surface in soundproof plate 3, Connection sheet 34 is equipped with fixation hole.Soundproof plate 3 is fixed by bolts on cabinet 1.
Strainer is equipped at air inlet 11.The outer wall of cabinet 1 is equipped with air outlet 14.
Radial circular arc soundproof plate noise reduction is used by the center of circle of 21 center of air intake duct, to reduce flow resistance, reduces noise, magnetcisuspension When floating blower 2 starts, extraneous gas enters interior of equipment cabinet by the air inlet 11 of cabinet, using internal radiation shape circular arc sound insulation Silencing cavity 30 between plate 3 enters air intake duct.Since soundproof plate uses arcuate structure, the resistance of air-flow can be reduced and then can be with The noise for reducing gas flowing can also eliminate master since soundproof plate uses the structure of surface porous metal plate and internal silencing cotton The some high frequency noises spread out of inside machine.
Magnetic suspension air blower host is installed to interior of equipment cabinet of the present invention by the present invention, air inlet setting on cabinet top, into Air flue surrounding is provided with sound gobo, and lower part surrounding door-plate inner wall is designed with the porous plate of noise reduction, connects on door-plate provided with forceful electric power Mouth, light current interface, stator cooling water interface, rotor cooling wind interface, air outlet.
When host work, external wind is from upper inlet port, into interior of equipment cabinet, and passes through the air duct between arc soundproof plate High pressure gas is discharged into air intake duct, after host centrifugal compressed from air outlet.Rotor and stator can generate big calorimetric simultaneously Amount, external cooling water enter host by the stator cooling water mouth on cabinet and take away stator heat, external cooling wind by turning Sub- cooling wind interface enters host, takes away rotor heat.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention Protection scope.
