Embodiment
For that can be illustrated more clearly that the present invention, hereby lift a preferred embodiment and coordinate attached drawing to describe in detail as after.It please join Fig. 2
Shown in Fig. 3, be first preferred embodiment of the invention cooling fan 100, include a guide unit, a guiding device 30,
One fan assembly 40 and a solar power generation unit 50.
The guide unit includes a pedestal 10 and an exhaust structure 20, which includes a bottom plate 12 and one
Stack shell 14, the wherein bottom plate 12 are installed in the top of a building and connect the interior of building with an entrance 121；The stack shell
14 set along the periphery of the entrance 121 and are incorporated into the bottom plate 12, and with one first engaging portion that is oppositely arranged and one the
Two engaging portions.First engaging portion is one first vertical wall 141, the first engaging portion vertical connection bottom plate 12 and it is highly low
Height in second engaging portion；One second vertical wall 142 and an inclined wall 143 collectively form second engaging portion, wherein should
Second vertical wall hang down 142 it is direct-connected connect the bottom plate 12, the inclined wall 143 connect 142 other end of the second vertical wall and upwards inwardly
Tilt.
The exhaust structure 20 is up-narrow and down-wide hollow housing, has one the 3rd engaging portion 22 and one the 4th being oppositely arranged
Engaging portion 24, the exhaust structure 20 are incorporated into the top of the pedestal 10 in a manner of it can change ornaments angle with respect to the pedestal 10,
That is, it is fixed on the first engaging portion of the pedestal 10 by the 3rd engaging portion 22, and is combined by the 4th engaging portion 24
In on the second engaging portion of the pedestal 10, and second can be incorporated into according to use demand and by the selectivity of the 4th engaging portion 24
Fix again after the apical margin of engaging portion to any position between root edge, i.e. vertical with the second of second engaging portion as shown in Figure 4
Wall 142 combines, or is combined as shown in Figure 5 with the inclined wall 143 of second engaging portion, reaches selective adjustment row whereby
The effect of angle between depressed structure 20 and the pedestal 10.In addition, the exhaust structure 20, which is further provided with an outlet 26, is located at the exhaust knot
The top of structure 20 and the entrance for connecting the pedestal 10.
The guiding device 30 is incorporated into the top of the exhaust structure 20 by multiple strut P, in this present embodiment, more may be used
Adjusted by varying the binding site of those struts P and the exhaust structure 20 between the guiding device 30 and the exhaust structure 20
Spacing.The guiding device 30 has a top 32,34 and one guidance part 36 of side plate.The side plate 34 is incorporated into the top 32
Periphery, and be located on the outside of the exhaust structure 20, wherein, the lower edge of the side plate 34 is less than the outlet of the exhaust structure 20.Should
Guidance part 36 is in funnel-form, is recessed from the top 32 and is formed and in face of the outlet 26 of the exhaust structure 20.36 surface of guidance part
The distance between 34 inner face of side plate, gradually increases towards the direction close to the pedestal 10, and the surface of the guidance part 36 is
Curved surface, in other embodiment, the surface of the guidance part also can be smooth inclined-plane.
The fan assembly 40 is incorporated into the inside of the guide unit, includes a rotational structure 42, a motor 44 and more
A blade 46；The rotational structure 42 sets 20 central part of exhaust structure and side combines those blades 46.The motor 44 is solid
Due to the opposite side of the rotational structure 42, to drive the rotational structure 42 to drive those blades 46 to rotate, by building
Portion's air is pumped through the entrance 121 toward 26 direction of outlet.In this present embodiment, which is DC Brushless Motor, more
It is durable and last a long time.
The solar power generation unit 50 is incorporated into the top of the guiding device 30, and is directly electrically connected to the fan assembly
40 motor 44, has a horizontal direction receiving plane 52, for receiving luminous energy and being converted to electric energy (direct current) output to the wind
Fan device 40, drives the fan assembly 40 to act so as to directly providing the energy.The solar power generation unit 50 directly electrically connects
The benefit of the motor 44 is connected to, in addition to it can reduce the cost that battery is set and further battery repairs, when more directly can utilize different
Between current difference caused by the solar power generation unit 50 caused by the sunlight strength put directly adjust the fan assembly 40
Rotating speed, and the setting of rotation speed of the fan control device can be reduced.
For example, building temperature is easily caused quickly to raise since the sunlight strength of noon is relatively strong, but because
Noon sunlight strength is stronger, can also cause the solar power generation unit 50 to produce higher electric current for giving the motor 44, Jin Erti
Rise the rotating speed of fan assembly 40 and there is preferable heat dissipation effect.Conversely, the sunlight strength of morning or the lower period of the day from 11 a.m. to 1 p.m are compared to noon
When sunlight strength it is weaker, building temperature does not have quick elevated situation, and weaker sunlight strength also can cause this too
Positive energy generator unit 50 produces relatively low electric current, and then reduces the rotating speed of fan assembly 40 and can avoid excessively radiating.Such one
Come, by the above-mentioned circuit design that the solar power generation unit 50 is directly electrically connected to the motor 44, in due course adjusting is built
The indoor temperature of thing is built, even if being not provided with the constant temperature effect that rotation speed of the fan control device also can reach building.It is this hair above
The structure design of bright cooling fan 100, when user installation cooling fan 100, you can change the pedestal 10 and the exhaust knot
Angle between structure 20, (figure is not after the receiving plane 52 on solar power generation unit 50 is in horizontal direction, then by fixing piece
Show) fix the position between the pedestal 10 and the exhaust structure 20.
In other words, it is in horizontal direction building that cooling fan 100, which is applicable not only to top, is equally applicable for top to tilt
The building roof of state, can more adjust the angle according to the heeling condition of top of building, make solar power generation unit 50
Receiving plane 52 be maintained at parallel, horizontal to state.Either morning, noon or afternoon hours, all can ensure that solar energy is uniform
Ground is irradiated on the solar power generation unit 50, is allowed the solar power generation unit 50 sufficiently to absorb solar energy, is reached photoelectricity
Change the optimization of the energy.
In addition, by above-mentioned structure design, it can also make the exhaust structure 20, the guiding device 30 and the fan assembly
40 central axis and ground in vertical state, and can provide better air circulation effect.That is, fan assembly 40 of action
The hot gas for driving the interior of building is entered into the entrance 121 of the pedestal 10 and by exhaust structure 20 tapered upward, afterwards
It is subject to the guidance part 36 to guide again along outside wall surface discharge in outside, to improve radiating efficiency, and then promotes inside and outside building
The gas circulation in portion and maintain the circulation of air, be effectively improved the excessive sultry situation of the interior of building temperature.
In the embodiment of other radiators, solar power generation unit structure can be also omitted, allows fan assembly directly to connect
Alternating current or other power generator are connect to obtain electric energy, are not limited with solar energy.And in the embodiment, pass through exhaust structure
It is mutually perpendicular between the central shaft and horizontal plane of outlet, so that the hot gas in building equally can be extended upward through successfully
Exhaust structure and discharge in outer, avoid being interfered in the gas process of circulation and influencing radiating efficiency.
The foregoing is merely preferably possible embodiments of the invention, as long as using description of the invention and claims
The equivalence changes that scope is made, ought to be included in the scope of patent protection of the present invention.
