Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Preferred embodiment:
The open a kind of cabinet air-conditioner of this preferred embodiment.As depicted in figs. 1 and 2, this cabinet air-conditioner includes shell
Body 1, the upper end of housing 1 is provided with air outlet 11, lower end is provided with lower air outlet 12, middle part is provided with
Air inlet 13；It is provided with at corresponding upper air outlet 11 in housing 1 at fan 21, corresponding lower air outlet 12
It is provided with at lower blower fan 22, corresponding air inlet 13 and is provided with heat exchanger 3；Heat exchanger 3 respectively with fan 21
And between lower blower fan 22, form wind flow path.
Using two fans structure and two fans to be respectively at the top and bottom of cabinet air-conditioner, two fans is simultaneously
Air-out, solves the unsteady flo w coupling that in existing apparatus, an air intake blower fan and an air-out blower fan series connection produce
Problem, it is to avoid the generation of abnormal sound；Reduce the exit velocity of each blower fan, it is to avoid because of high velocity air
The bad Rotation Noise that jet and collision cause is there is in blower interior and exit；Air outlet area increases
Greatly, air output is big, fast to indoor temperature governing speed, efficiency is high.
The concrete shape of heat exchanger 3 does not limits, in order to enable preferably air intake, and the preferably cylindrical knot of heat exchanger 3
Structure, air inlet 13 includes the multiple holes being arranged in housing 1 circumference, and above-mentioned multiple holes are at least about housing 1
One week.
Aperture can not be excessive, in order to avoid there being foreign material to be inhaled in housing 1, there is potential safety hazard；Aperture can not
Too small, air-flow easily produces noise when through aperture.Preferably, the diameter in hole is between 4-10mm, often
Spacing between two adjacent holes is 7-15mm, is ensureing that air inlet 13 area is unlikely on the premise of enough
Spine sound is caused because intake is uneven.
The aperture of all well can be identical can also being varied from, from the side at the middle part of housing 1 to end
Upwards (that is, from the middle part of housing 1 to fan 21 direction or on lower blower fan 22 direction), hole
Diameter becomes big successively.Preferably, from the direction of the upper end of housing 1 to lower end, the diameter change in multiple holes
Meet the quadratic function form of opening upwards.
Air intake can be adjusted by the density changing hole, it is preferred that percent opening when the diameter in hole is constant
(numerical value of area addition gained porose in unit are) controls in the range of 40%-80%, and perforate divides
Cloth meets runner rule.
On the basis of said structure, in heat exchanger 3, it is provided with fin.In order to improve heat exchange efficiency, reduction
Windage, guarantee air intake will not impact fin, can use circular fin, and fin is perpendicular to cylinder and changes
The axis of hot device, fin setting direction is preferably identical with the air intake direction of air inlet 13；Straight sheet can also be used
The fin of shape, one end of fin near the axis of heat exchanger, the other end near air inlet 13, i.e. fin in
Radial；Straight plate fins can also be arranged by the parallel axis with heat exchanger, and cross section is also radially.
Said structure can reduce complete machine noise 1dB (A), can reduce energy consumption, and heat exchange area increases, and exports stream simultaneously
Amount increases about 1.5 times.
The air-out direction of the air-out direction of upper air outlet 11 and lower air outlet 12 can be identical, can be contrary,
Can also be between the two in the angle more than 0 °, less than 180 °.
Housing 1 is cylinder-like structure, and heat exchanger 3 is cylindrical structural；The axis of housing 1, heat exchanger 3
The fan blade axis of axis, the fan blade axis of fan 21 and lower blower fan 22 coincide, it is ensured that surrounding air intake
Apart from identical, flowing uniformly, aerodynamic noise performance is good.
Fan 21 and lower blower fan 22 are preferably centrifugal blower, the outlet court of the spiral case 4 of every centrifugal blower
To corresponding air outlet.
Note, above are only presently preferred embodiments of the present invention and the know-why used.People in the art
Member, it will be appreciated that the invention is not restricted to specific embodiment described here, for a person skilled in the art can
Carry out various obvious change, readjust and substitute without departing from protection scope of the present invention.Therefore,
Although being described in further detail the present invention by above example, but the present invention is not limited only to
Above example, without departing from the inventive concept, it is also possible to include that other equivalences more are implemented
Example, and the scope of the present invention is determined by scope of the appended claims.
