Description
Technical field
The utility model belongs to art of refrigeration units, and in particular to a kind of novel cooling outlet air piece and fan.
Background technology
In recent years, due to global warming, the temperature of summer is higher and higher, especially in many big cities, summer
Heat often allow people that can not endure.
Traditional cooling in summer mode, which is had time, downgrades mild fan for cooling etc..But fan can only simply exhausting blow,
And room temperature can not be effectively reduced, it can just feel nice and cool only when wind is blown to.And although air-conditioning can play the effect of cooling
Fruit, but air-conditioning is more power-consuming, and the exhaust gas of air-conditioning discharge can increase from global warming phenomenon.
Invention content
The utility model is in view of the shortcomings of the prior art, provide a kind of fan to cool down and fan outlet air piece.
The technical scheme that the utility model is provided is as follows：
A kind of novel cooling outlet air piece, including outlet air piece ontology and connecting portion, the outlet air piece ontology is equipped at least
One funnel shaped gas passage, the gas passage includes intake section and outlet portion, and the minimum-value aperture of the intake section is big
In the maximum diameter of hole equal to the outlet portion.
Under fan effect, air is constantly pushed into the intake section of outlet air piece, leads to the local pressure in intake section
Raising, and pressure is returned to normal atmosphere (An) after air flow to the external world by outlet portion.At this point, it is equivalent in outlet portion
Inside and outside between form stable pressure differential, each time air by the process of gas passage that is, once throttling swollen
It is swollen.According to thermodynamic principles, air temperature after throttling expansion can be declined, if throttling expansion is repeated to air,
Temperature can constantly decline.The outlet air piece of the present embodiment is exactly to reduce air themperature using the principle of throttling expansion.
Further, the outlet air piece ontology is bowl-type, and the connecting portion includes being arranged at the outlet air piece body edges
Buckle.
Outlet air piece ontology is bowl-type, consistent with the structure of most domestic fans in the market so that it can direct generation
For the preceding mesh sheet of domestic fan, directly it is buckled on fan and is used by buckle.
Further, the connecting portion includes being arranged on the magnet at the outlet air piece body central.
Connecting portion includes being arranged on the magnet at the outlet air piece body central.Different from buckle, magnet can directly be inhaled
It is attached on existing fan, the preceding mesh sheet without removing existing fan is installed, and dismounting is simple and convenient.
Further, the intake section and outlet portion are cone, and the taper of the intake section is more than the outlet portion
Taper.
The taper of intake section is more than the taper in outlet portion so that the one end of intake section far from the outlet portion forms larger
Opening, gas as much as possible is guided to enter gas passage.
Further, the gas passage annular arrangement is on the outlet air piece ontology.
Gas passage is arranged in a ring on outlet air piece ontology, can be reduced by the way of the annular arrangement between gas passage
Gap, improve space availability ratio.
The utility model also protects a kind of fan, and the preceding mesh sheet of the fan is outlet air piece as described above.
Further, the outlet air piece ontology is bowl-type, and the edge of the outlet air piece ontology is equipped with described for connecting
The buckle of fan.
Further, the magnet for connecting the fan is equipped at the center of the outlet air piece ontology.
The fan of cooling outlet air piece as described above is installed additional, air is when across the outlet air piece under throttle effect effect
Temperature reduces.Can constantly there be air to pass through the gas passage during due to fan work, with the accumulation of fan work time,
More and more air themperatures decline, so as to achieve the effect that reduce room temperature.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Fig. 1 and Fig. 2 show a kind of fan of the present embodiment, wherein, the preceding mesh sheet of fan is a kind of novel cooling outlet air
Piece, the outlet air piece are connected to by connecting portion 20 on fan.
The preceding mesh sheet of fan is replaced with into cooling outlet air piece, air is when across the outlet air piece due to the work of throttle effect
With temperature reduces.And can constantly there is air to pass through the gas passage 11 during due to fan work, with the fan work time
Accumulation, more and more air themperatures decline, so as to achieve the effect that reduce room temperature.
Fig. 3 and Fig. 4 show the novel cooling outlet air piece of the present embodiment, including outlet air piece ontology 10 and connecting portion 20, institute
Outlet air piece ontology 10 is stated equipped at least one funnel shaped gas passage 11.In the present embodiment, on the outlet air piece ontology 10
Equipped with multiple gas passages 11, and the gas passage 11 is arranged in a ring, to reduce the gap of adjacent gas channel 11, is improved
The coverage rate of gas passage 11 so as to increase air output, improves cooling efficiency.
As shown in figure 5, the gas passage 11 includes intake section 111 and outlet portion 112, the minimum of the intake section 111
Aperture is more than or equal to the maximum diameter of hole in the outlet portion 112.
Under fan effect, air is constantly pushed into the intake section of outlet air piece, leads to the local pressure in intake section
Raising, and pressure is returned to normal atmosphere (An) after air flow to the external world by outlet portion.At this point, it is equivalent in outlet portion
Inside and outside between form stable pressure differential, each time air by the process of gas passage that is, once throttling swollen
It is swollen.According to thermodynamic principles, air temperature after throttling expansion can be declined, if throttling expansion is repeated to air,
Temperature can constantly decline.The fan of the present embodiment utilizes throttling expansion principle, makes the continuous circulation temperature lowering of air, reaches refrigeration effect
Fruit.
Preferably, the intake section 111 and outlet portion 112 are cone, and the taper of the intake section 111 is more than
The taper in the outlet portion 112.
The design of taper is so that one end open of the intake section 111 far from the outlet portion 112 is larger, so as to guide more
More ground air enters gas passage 11.
In an embodiment of the present embodiment, the outlet air piece ontology 10 is bowl-type, and the connecting portion 20 includes setting
Buckle 21 in 10 edge of outlet air piece ontology.
In the another embodiment of the present embodiment, the connecting portion 20 includes being arranged on 10 center of outlet air piece ontology
The magnet 22 at place.
Outlet air piece is mounted on by buckle 21 or magnet 22 on existing fan, to replace the preceding net of existing fan
Piece.Above-mentioned mounting means is simple in structure, easy for installation, and applied widely.
In short, the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
All any modification, equivalent and improvement made within spirit of the present utility model and principle etc., should be included in this practicality
Within novel protection domain.
