Abstract
The utility model discloses a high-low voltage variable frequency motor fan which comprises a fan shell, backwards-inclined type impellers and curved-path deflectors. A volute is arranged in the fan shell, a plurality of motors are perpendicularly arranged on the top of the fan shell, an air inlet is formed in the bottom of the fan shell, air outlets are formed in the two sides of the fan shell respectively, a plurality of backwards-inclined type impellers are arranged in the volute and connected with the motors in a matched mode, a wind collecting ring is arranged at the bottom, and the curved-path deflectors are arranged in the air outlets. The high-low voltage variable frequency motor fan can effectively dissipate heat when the motors work at low frequency, is low in noise, and guarantees the fact that heat is dissipated effectively and work efficiency is improved when the motors work at low frequency.
Description
Technical field
This practical blower fan technical field that newly relates to, is specifically related to a kind of high low pressure variable-frequency motor blower fan.
Background technique
When existing high low pressure variable-frequency motor blower fan moves in low frequency environments, result of ventilating heat dissipation is not obvious, cannot meet the requirements of radiating effect, and when operation, noise is larger, affects working environment.
Summary of the invention
This practical new object is to overcome the above problem that prior art exists, and a kind of high low pressure variable-frequency motor blower fan is provided, this practical newly energy efficiently radiates heat when motor low frequency operation, and noise is little, guaranteed that motor is when low frequency operation, energy efficiently radiates heat, increases work efficiency.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, basis is practical to be newly achieved through the following technical solutions:
High low pressure variable-frequency motor blower fan, comprise Blower Housing, backswept impeller He Qu road guide plate, described Blower Housing top is vertically installed with some motors, bottom is provided with intake grill, and both sides are all provided with exhaust outlet, described Blower Housing inside is provided with spiral case, described spiral case both sides are all provided with spiral case air-out opening, and bottom is provided with spiral case air intake opening, described spiral case air-out opening is connected with exhaust outlet, described spiral case air intake opening is arranged at intake grill top, described spiral case inside is provided with some backswept impellers, described backswept impeller and motor are connected, and bottom is provided with collection solar or lunar halo, in described exhaust outlet, be provided with the guide plate for noise reduction.
Further, described guide plate cross section is W type, and one end is arranged at exhaust outlet top, and the other end is arranged in the exhaust outlet of spiral case air-out opening one side.
Further, on described Blower Housing, be also provided with outlet box, and top is provided with some lifting bolts.
Further, the air-out direction of described exhaust outlet makes progress, and top is provided with chain link fence cover plate.
Further, the quantity of described motor and backswept impeller is 2.
This practical new beneficial effect is:
1, draught fan impeller adopts backswept impeller, effectively reduces noise;
2, in blower fan chamber, the installing space of impeller, around with spiral case, is beneficial to the raising of blast, air quantity;
3, air inlet is provided with collection solar or lunar halo, and inserts one section of profile ID, is convenient to wind-guiding and effectively reduces wind loss;
4, fan outlet adopts the guide plate noise reduction of bent road to process, and effectively reduces noise;
5, fan outlet is provided with chain link fence cover plate, handsome in appearance, prevents that foreign material from falling into its inside.
Above-mentioned explanation is only the general introduction of this practical new solution, in order to better understand this practical new technological means, and can be implemented according to the content of specification, below with this practical new preferred embodiment and coordinate accompanying drawing to be described in detail as follows.This practical new embodiment is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide this practical new further understanding, forms the application's a part, and this practical new schematic description and description is used for explaining that this is practical new, does not form this practical new improper restriction.In the accompanying drawings:
Fig. 1 is this practical new overall structure partial cross section schematic diagram;
Fig. 2 is this practical new side view.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe that this is practical new in detail.
Shown in Fig. 1 and Fig. 2, high low pressure variable-frequency motor blower fan, comprise Blower Housing 1, backswept impeller 5 He Qu road guide plates 8, Blower Housing 1 top is vertically installed with two motors 2, bottom is provided with intake grill 4, and both sides are all provided with exhaust outlet 3, exhaust outlet 3 tops are provided with chain link fence cover plate 9, for preventing that foreign material from dropping; Blower Housing 1 inside is also provided with spiral case 6, and spiral case 6 inside are provided with two backswept impellers 5, and backswept impeller 5 is connected with motor 2, and bottom is provided with collection solar or lunar halo 7; In exhaust outlet 3, be provided with guide plate 8, guide plate 8 cross sections are W type, and one end is arranged at exhaust outlet 3 tops, and the other end is arranged in the exhaust outlet 3 of spiral case 6 one sides, and guide plate 8 has decrease of noise functions; On Blower Housing, 1 is also provided with outlet box 13, and top is provided with two dry lifting bolts 10, conveniently installs and uses.
The working principle of the present embodiment is as follows:
This practical new described blower fan can easily be lifted and is placed on the device that needs heat dissipation exhaust by lifting bolt 10, by outlet box, connect power supply 13.During work, motor 2 rotates, drive backswept impeller 5 to rotate and produce wind-force, the heat of device enters spiral case air intake opening 12 from intake grill 4, and by collecting the effective wind-guiding of solar or lunar halo 7 and effectively reducing air quantity loss, then enter in spiral case 6, spiral case 6 contributes to blast, the raising of air quantity, and discharge from the spiral case air-out opening 11 of spiral case 6 both sides by the rotation of backswept impeller 5, enter in exhaust outlet 3, because spiral case 6 and collection solar or lunar halo 7 are by blast, air quantity increases, directly get rid of and have very large noise, turn round and look at by the design of guide plate 8, make it at the interior noise reduction of exhaust outlet 3, then discharge.This is practical new under the prerequisite of working power that does not change motor 2, and the effect by spiral case 6 and collection solar or lunar halo 7, effectively improves radiating effect, and excellent noise reduction effect.
The foregoing is only this practical new preferred embodiment, be not limited to that this is practical new, for a person skilled in the art, this is practical newly can have various modifications and variations.All within this practical new spirit and principle, any modification of doing, be equal to replacements, improvement etc., within all should being included in practical new protection domain.
