Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
With reference to figure 1, a kind of ventilating fan with air cooling equipment, comprise the ventilating fan 1 be installed on working room's exhaust port, described ventilating fan is made up of the fan blade 8 on front side of motor 2 and motor, and described electrical machinery of ventilator outside is provided with from cooling adjustable negative pressure cooling air wind-guiding isolation mounting 3.This device not only can isolate hot air flow, prevents dust granules to the infringement of motor simultaneously, and isolation etchant gas is to the infringement of motor.
In the present embodiment, in order to reach best cooling-down effect to motor, describedly to be made up of a tubaeform case 4 and the cold wind inlet tube 6 that is connected to tubaeform case closing in place 5 from cooling adjustable negative pressure cooling air wind-guiding isolation mounting 3, described tubaeform case opening 7 is positioned at ventilating fan fan blade 8 dead astern, so that the abundant cooling motor of cold wind, and tubaeform case near the root of ventilating fan fan blade to make ventilating fan work time through suction function time motor surface or shielding can in cold wind front side in the middle part of ventilating fan of flowing through discharge, described ventilating fan fan blade periphery is also provided with air conducting tube 10.
This isolation mounting: (1), because horn mouth is near fan blade rear end, is conducive to effective utilization of negative pressure; (2) temperature during machine operation simultaneously detected according to producer, can regulate bell-mouthed size; In certain ventilation bore, if horn mouth is excessive, then negative pressure is large, and negative pressure greatly then cold airflow is large, and negative pressure greatly then causes hot air flow little, makes cold airflow and hot air flow to reach balance, and the working efficiency of ventilating fan is reduced; If there is horn mouth too small, negative pressure can be caused to reduce, negative pressure reduces then cold airflow and reduces, and cause motor radiating not enough, affect the working life of motor, cold airflow is little simultaneously, hot air flow can be caused excessive, affect the working efficiency of cold wind.And the size of this tubaeform case also helps the negative pressure in balance hot air flow and tubaeform case, if hot gas flows through by force, causes the effect of negative pressure to reduce, if hot air flow is less than negative pressure, then easily causes hot air flow to reflux.The motor surface temperature that producer can experimentally measure carries out the size of reasonably preferably case, and the ratio of cold wind and hot blast is mainly derived from practice.Also be reserved with simultaneously and carry out regulating the case changed according to user's user demand, facilitate user to regulate the size of case.
In the present embodiment, in order to stop the hot blast of working room, prevent hot air flow from entering cool air hose, the distance 13 between described tubaeform case end face and fan blade rear portion is 1 ~ 5mm.If reduce apart from the excessive negative pressure that just there will be, affect the working efficiency of isolation mounting.
In the present embodiment, in order to ensure motor low-temperature working environment, cold wind inlet tube is avoided to absorb the heat of the hot air flow outside case, negative pressure in cool air hose is had an impact, the horn-like closing in place outer wall of described tubaeform case also covers establishes a case 11, thermal insulating material 9 is provided with, to guarantee that chamber internal air pressure is not affected by hot air flow in the chamber that described case and tubaeform case are formed.
The outer wall of above-mentioned tubaeform case is streamlined, little to the resistance of air-flow, effectively can reduce the resistance deriving from ventilating fan rear end, increase flow velocity and the air quantity of inside working chamber air-flow, and this tubaeform case be conducive to isolate air-flow, with in effective scope for motor radiating.
In the present embodiment, conveniently user uses, the size of adjustment negative pressure easily and effectively, the import of described cold wind inlet tube is provided with cold flow controlling device 12, described cold flow controlling device is mechanical type or autoamtic control type, this device is provided with adjustment button or toggle for regulating cold wind size, or is the radial adjustable plate 121 in the ingress one being arranged at cold wind inlet tube, the inwall of adjustable plate one end and cold wind inlet tube is hinged, and the movable end of adjustable plate passes cold wind inlet tube.。Such as, when stirring toggle switch to the right, the negative pressure passing into cold wind inlet tube increases, and when stirring toggle left, the negative pressure passing into cold wind inlet tube reduces, and can regulate according to the actual service condition of user to the vacuum magnitude in cooling tube.
Specific works process: during ventilating fan work, the hot blast of working room flows through from tubaeform case outer wall by the pumping action by fan blade, then passes between fan blade, thus discharges the hot gas in working room; The cold wind size introduced in cold wind inlet tube is regulated by cold flow controlling device, enter in tubaeform case to make cold wind from cold wind inlet tube, cold wind is made to flow through motor surface and bell-mouthed inwall, flow out from fan blade root, again outside fan blade pumping action discharge chamber, thus be motor and the cooling of tubaeform case, reduce the temperature of motor, ensure that working life and the effect of motor.
Embodiment two, referring to figs. 2 to Fig. 5, in order to the user demand according to user, the aperture of tubaeform case is regulated, described tubaeform case 4 is made up of the cylindrical body 41 near motor path and the skirt section, large footpath 42 near exhaust outlet, radial coaming plate 43 is provided with between described skirt section, large footpath and cylindrical body, skirt section, described large footpath is made up of some arc skirtboards 421, the medial arc skirtboard 422 fastening two adjacent arc clearance between skirt panels is provided with between two adjacent arc skirtboards, axial stem 44 is connected in the middle part of each arc skirtboard, described axial stem and radial coaming plate sliding connection change with the skirt section diameter realizing arc skirtboard and formed and regulate.
The working principle of the present embodiment: user in use regulates according to the diameter of temperature to tubaeform case of working room, when temperature is higher, the aperture of the Manual gas valve being arranged at the cold wind controlling device of cold wind inlet tube suction tude is tuned up, increase to make the negative pressure entered in cold wind inlet tube, simultaneously, by tubaeform case arc skirtboard and medial arc skirtboard stretch out, the aperture in skirt section is tuned up, thus the negative pressure passed through from motor perimembranous is increased, to be better electric motor temperature reduction; When the operating ambient temperature of motor is lower, enters flow in cold wind inlet tube by the aperture that reduces Manual gas valve to reduce negative pressure, arc cover plate is inwardly shunk the aperture reducing tubaeform case simultaneously.
Embodiment three, with reference to figure 6 and Fig. 7, regulate according to the size of motor temperature to tubaeform case detected aborning to realize producer, described tubaeform case is made up of the path cylindrical body near motor and the skirt section, large footpath near exhaust outlet, be filled with thermal insulating material in described cylindrical body, described tubaeform case and cold wind inlet tube are that dismoutability is connected.
The working method of the present embodiment: regulated the negative pressure flow entered in cold wind inlet tube by the cold flow controlling device on cold wind inlet tube, the replaceable loudspeaker shape case when temperature is higher simultaneously, increase the internal diameter of tubaeform case, when the temperature is low, the less tubaeform case of an internal diameter is changed.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
