Figures 1 and 2 show that the embodiment one of ventilation case of the present utility model, this ventilation case includes housing 10, air inlet
11 and air outlet 12, air inlet 11 is arranged on one end of housing 10, and air outlet 12 is arranged on the other end of housing 10.Air inlet
Housing 10 between 11 and air outlet 12 gradually tapers up on the direction of air inlet 11 to air outlet 12, is completely formed tapering type knot
Structure, tapering type structure is compressed for the air-flow entering air inlet 11.In use, air-flow can enter shell from air inlet 11
In body 10, the tapering type structure that the air-flow after entrance housing 10 can be formed by housing 10 gradually reduces.Air-flow after compression can produce
Can in raw so that the temperature of air-flow has raised, the gas flow temperature the deepest along with the degree of depth entering housing 10 is the highest.According to heat
Transmission effects, the heat of the air-flow of the higher temperature compressed can air-flow that gradually temperature is relatively low at air inlet 11 conduct heat, from
And the temperature of the air-flow compressed in making housing 10 is similar to the temperature of air-flow of air inlet 11 end.Afterwards, air-flow meeting
Blowing out from air outlet 12, after the air-flow of blowout has broken away from the restriction of housing 10, can spread suddenly, pressure and flow velocity all can reduce.
According to the equation of gas state, the air-flow of blowout can meet below equation:
Wherein P1、V1And T1, represent just from the pressure of the air-flow also not spread, flow velocity and the temperature of air outlet 12 blowout
Degree, P2、V2And T2, represent the pressure of air-flow, flow velocity and the temperature after the expanding of air outlet 12 blowout.
It can be seen that, because of P2、V2After expanding, pressure and the flow velocity of air-flow all can reduce, thus cause T2Also synchronize to reduce, also
I.e. T2＜ T1.So, will be more lower slightly than air inlet 11 enters the temperature of air-flow from the temperature of the air-flow of air outlet 12 blowout,
So that the user of blowing feels nice and cool, comfortable.
As it is shown in figure 1, in the technical scheme of embodiment one, the area of passage of air outlet 12 flows less than crossing of air inlet 11
Area.The area of passage of air inlet 11 is relatively big, is on the one hand easy to air intake, on the other hand also allows for heat in housing 10 to air intake
Mouth 11 spreads out of.
As it is shown in figure 1, in the technical scheme of embodiment one, optionally, the area of passage of air inlet 11 is air outlet 12
1.5 times to 4 times of area of passage.Compression effectiveness and the heat transfer effect that can significantly improve housing 10 is so set.Preferably
, the area of passage of air inlet 11 is 2 times to 3 times of the area of passage of air outlet 12.
As it is shown in figure 1, in the technical scheme of embodiment one, housing 10 is trumpet type, air inlet 11 is the big of housing 10
Mouthful, air outlet 12 is the osculum of housing 10.The air-flow that air inlet 11 enters can be played good pressure by the housing 10 of trumpet type
Contracting effect, air inlet 11 is big mouth, also allows for heat and spreads out of to air inlet 11 in housing 10.
As depicted in figs. 1 and 2, being provided with boss 13 on the inwall of tapering type structure, the effect of boss 13 is disturbance
Air-flow so that air-flow produces vortex when boss 13, and then is easy to the air-flow at vortex and the air-flow at air inlet 11
Form heat exchange, heat is transmitted to air inlet 11 so that the temperature of the air-flow compressed in housing 10 is similar to air inlet 11 end
The temperature of the air-flow at face.
In order to strengthen the heat exchange efficiency in tapering type structure, boss 13 is annular boss, along the inwall of tapering type structure
Circumferentially disposed.Make can be formed at airflow passes annular boss place vortex, and then strengthen heat exchange efficiency.
As depicted in figs. 1 and 2, in the technical scheme of embodiment one, boss 13 is multiple, and multiple boss 13 is at air inlet
It is arranged at intervals on the inwall of tapering type structure on the direction of 11 to air outlet 12.Multiple boss 13 can allow the gas flowed through
Stream forms multiple tracks vortex, and then is gradually transmitted to air inlet 11 by heat, the temperature of the air-flow compressed in always making housing 10
Degree is similar to the temperature of the air-flow of air inlet 11 end.Optionally, multiple boss 13 are arranged equally spaced at tapering type structure
Inwall on.
The technical scheme of the ventilation case (not shown) of embodiment two is compared with the technical scheme of embodiment one, and difference is only
Being that housing 10 is taper, air inlet 11 is the big mouth of housing 10, and air outlet 12 is the osculum of housing 10.Same, taper
The tapering type structure that housing 10 is formed, also can be effectively compressed the air-flow entering housing 10.
The technical scheme of the ventilation case (not shown) of embodiment three is compared with the technical scheme of embodiment one, and difference is only
The part of the housing 10 being between air inlet 11 and air outlet 12 gradually tapers up on the direction of air inlet 11 to air outlet 12
Form tapering type structure.In use, it is only necessary to above-mentioned tapering type structure can be formed, the air-flow entered from air inlet 11 is entered
Row compression, then transfers heat at air inlet 11, then the air-flow after compression is maintained at compressive state, then is transferred at air outlet 12
Blowout, just can play cooling-down effect to a certain extent, make the user of blowing feel nice and cool, comfortable.
As shown in Figure 3 and Figure 4, this utility model also includes a kind of fan, according to the embodiment of fan of the present utility model
Including ventilation case, ventilation case is above-mentioned ventilation case.By this ventilation case so that fan goes out the wind energy blown compares ambient temperature
It is more lower slightly, so that the user of blowing feels nice and cool, comfortable.Optionally, as it is shown on figure 3, this fan also includes flabellum 20,
Flabellum 20 is rotatably arranged in ventilation case, is used for air inlet 11 suction airflow from housing 10, then blows out from air outlet 12.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
