It can be the connection inside two elements." first " " second " " third " " the 4th " does not represent any sequence relation, be only for
The differentiation for facilitating description to carry out.For the ordinary skill in the art, it can understand that above-mentioned term exists with concrete condition
Concrete meaning in the utility model.At the time of " current " is when executing certain movement, occur multiple current in text, is at any time
Between passage in record in real time.
The problem slow for current wind cooling refrigerator air supply velocity, air-supply range is close, the utility model provide wind cooling refrigerator
Air supply device and wind cooling refrigerator.
Product, method etc. will be described in detail by basic engineering, extension design and alternative design below.
A kind of air supply device of wind cooling refrigerator, as shown in Figs 1-4, the bodies top of air supply device are arranged more than one and go out
Air port 1, air outlet 1 are cylindrical in shape, and the longitudinal section area of air outlet 1 is tapered from air intake 11 to outlet air end 12.Air intake 11 with give
The ontology air-supply passage of wind apparatus is connected, and outlet air end 12 is the end of refrigerant gas discharge.When refrigerant gas flows through air outlet 1 with
The tapered volume of air outlet 1 changes, and air velocity is collected, and can quickly spray, and after ejection, when the speed of air-flow can be long
Between keep high speed, collected state, so as to improve range of the cold wind in refrigerator.
Since the tubular of air outlet 1 itself is unconventional tubular, from the longitudinal section of air intake 11, outlet air end 12
It is interpreted as cutting perpendicular to airflow direction, the longitudinal section area of each cross-sectional shapes.
In view of the smooth performance of gas flowing improves air flow rate, therefore, side tapered in some embodiments
Formula is streamlined tapered.
It is streamlined to can be understood as resistance suffered when object moves in a fluid, it is by two reasons of interior friction and vortex
Caused.In speed very little, the size of resistance depends mainly on interior friction.Vortex is depended mainly on when speed is larger,
Speed is faster, and the effect of vortex is bigger.In order to effectively reduce resistance it is necessary to trying to avoid the formation being vortexed.By to fish
Swimming observed, find all fishes for swimming fastly, such as hairtail, shark, all there is a kind of shape of special cigar formula
Shape.It draws a conclusion further through many experiments, object is made into this shape, vortex effect can be reduced really or avoid the shape being vortexed
At, thus fluid is greatly reduced to its resistance.This shape is called streamlined, can reduce gas flow resistance.
In some embodiments, it also can satisfy in relation to tapered mode as follows: from air intake 11 to outlet air end 12, outlet air
The longitudinal section variation of mouth 1 is consistent with airflow volume variation, rises to wind speed higher.Herein it is " consistent " be understood that
Are as follows: variation ratio is identical.Longitudinal section is the cut surface perpendicular to gas flow direction cutting air outlet 1.
It in view of space is larger in refrigerator, needs uniformly to carry out wind cooling temperature lowering, to reach the temperature base of refrigerator inside everywhere
Originally be consistent, so, air outlet 1 can be set to it is multiple, in air supply device top equidistantly distributed.
Since air outlet 1 is set to the top of air supply device ontology, in some embodiments, in the air supply device and refrigerator
The top of gallbladder is assembled, and a side wall (roof) of air outlet 1 is identical as the flatness of liner inner surface of wind cooling refrigerator, with fitting
Liner inner surface.Air outlet 1 abuts inner container of icebox top as a result, and the cold air physical efficiency being discharged from air outlet 1 is close to inner container of icebox
Surface flow forms wall attachment effect, forms the jet stream flowed along wall surface.Distance is small between air-flow top and ceiling, rolls up the air of suction
Amount is few, and top flow velocity is big, and static pressure is small, and lower part static pressure is big, and upper and lower pressure difference makes air-flow be attached at liner surface flow.Delay air-flow exists
Diffusion time in traveling, under same air outlet velocity, the range by wall moving air is longer, further increases air-cooled effect
Fruit.
Cold airflow moves from top to bottom, and the air-flow in wind cooling refrigerator also uses the top-down type of flow substantially, air-cooled
Top is arranged in the air outlet 1 of refrigerator, is based on this, and in some embodiments, the upper side wall of air outlet 1 is interior with wind cooling refrigerator liner
Top surface fitting, the gas being discharged from air outlet 1 are flowed along the inner top surface of wind cooling refrigerator.Cold airflow is dynamic certain along the default surface current of liner
After distance, slowly diffusion downwards, carries out wind cooling temperature lowering.
When air-flow is discharged from air outlet 1, arc water conservancy diversion is still used, i.e. the side of air outlet 1 is enclosed by plane and curved surface
At plane is the binding face for being bonded wind cooling refrigerator liner inner surface, and curved surface is used for water conservancy diversion.The curved surface is preferably arc surface.
The air intake 11 of air outlet 1 is tapered to outlet air end 12, and gas is flowed from air supply device bulk flow to 1 gas of air outlet
Body volume change, air velocity enhancing.Moreover, the side wall of air outlet 1 is close to the liner of wind cooling refrigerator, it is discharged from air outlet 1
Air-flow be close to side wall of inner flowing, according to jet current principle is sticked, under same air outlet velocity, by the range of wall moving air
It is longer.
The utility model additionally provides a kind of wind cooling refrigerator comprising above-mentioned air supply device and refrigerator body, refrigerator body
The air outlet of interior setting liner, air supply device passes through liner, and the upper side of air supply device is bonded with the inner top surface of liner.Air-supply
Device is mounted between liner and refrigerator shell.
The wind cooling refrigerator, by optimization inlet shape, increases cold air and goes out when complete machine power consumption does not change
One's intention as revealed in what one says speed；By designing air outlet position, the range of cold air is further increased；The above two o'clock synthesis result, can make complete machine
When power consumption does not change, air-supply range of jet is improved, the cooled region of cold air is increased, enhances the equal of refrigerator inside air themperature
Even property.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
