Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
After a series of experimental verification, find that evaporimeter its fin in reality processing is from left to right blocks of to be superimposed, compress from top to bottom from right side, this just causes the fin clearance (wearing U pipe side) on the left of evaporimeter can be less than right side (eyesight elbow connection side) gap again.One skilled in the art will appreciate that the size in gap affects intake, the large air intake in gap is many, and the little air intake in gap is few.Thus causing evaporimeter right-hand member intake can be larger than left end, two ends, evaporimeter left and right heat transfer effect is unequal, can not give full play to evaporator heat exchange effect, affect performance boost.Meanwhile, this can cause inner two ends, left and right, air channel to occur the temperature difference, thus causes condensation weak effect; And due to two ends, left and right intake unequal, cause two ends, left and right air flow pressure and eddy current in air channel inconsistent, cause overall noise weak effect, this causes one of reason that the noise of air-conditioner is larger.
As shown in Figure 1 to Figure 3, the air-conditioner of the present embodiment comprises evaporimeter, spiral case and is arranged on spiral case inside and the through-flow fan blade 1 be positioned at below evaporimeter, spiral case comprises: the first spiral case 10 and the second spiral case 20, first spiral case 10 is arranged on the side of through-flow fan blade 1 and the axis direction along through-flow fan blade 1 extends, and the first spiral case 10 forms the first snail tongue 11 towards the end of through-flow fan blade 1 air inlet; Second spiral case 20 is arranged on the opposite side of through-flow fan blade 1 and the axis direction along through-flow fan blade 1 extends, and the second spiral case 20 forms the second snail tongue 21 towards the end of through-flow fan blade 1 air inlet.Gap between the fin of the evaporimeter of the air-conditioner of the present embodiment reduces along the first end in the axial direction of air-conditioner gradually to the direction of the second end in the axial direction, and the first snail tongue 11 and the gap between the second snail tongue 21 and through-flow fan blade 1 all correspondingly reduce gradually from the first end of air-conditioner to the direction of the second end.As depicted in figs. 1 and 2, the gap between the first snail tongue 11 and through-flow fan blade 1 is gradient to maximal clearance B from minimum clearance A, and the second snail tongue 21 is gradient to maximal clearance D with the gap of through-flow fan blade 1 from minimum clearance C.
Those skilled in the art can know, as feasible embodiment, also the gap between the first snail tongue 11 and through-flow fan blade 1 only can be made all correspondingly to reduce gradually from air-conditioner first end in the axial direction to the direction of the second end in the axial direction, or only make the gap between the second snail tongue 21 and through-flow fan blade 1 all correspondingly reduce gradually from air-conditioner first end to the direction of the second end.
Generally evaporimeter its fin in reality processing is from left to right blocks of is superimposed, and in the present embodiment, the left end of air-conditioner is air-conditioner first end in the axial direction, and the right-hand member of air-conditioner is the second end of air-conditioner.
Preferably, the first snail tongue 11 and the minimum clearance between the second snail tongue 21 and through-flow fan blade 1 are all in the scope of 2 to 8mm.First snail tongue 11 and the maximal clearance between the second snail tongue 21 and through-flow fan blade 1 are all in the scope of 3 to 15mm.In the present embodiment, minimum clearance is the gap between the first snail tongue 11 of air-conditioner first end and through-flow fan blade 1, and maximal clearance is the gap between the second snail tongue 21 of air-conditioner second end and through-flow fan blade 1.
Test according to the present embodiment, contrast noise, crest frequency and air quantity with the air-conditioner of prior art, test as follows:
Test condition: sound pick-up is positioned over 1m place before outer machine, and sound pick-up is apart from ground level 1m; Measurement condition: under voltage stabilizing electrical testing condition, air supply pattern opened by air-conditioning; Under above-mentioned test condition, working condition, air-conditioning is run 40 minutes respectively under low windscreen refrigeration mode, middle windscreen refrigeration mode, high windscreen refrigeration mode, measure this Experimental comparison's data.L is that air-conditioning is when being in low windscreen refrigeration mode; M is that air-conditioning is when being in middle windscreen refrigeration mode; H is that air-conditioning is when being in high windscreen refrigeration mode; SH is air-conditioning when being in superelevation windscreen refrigeration mode, and in table, data are frequency values and the air-out value of overall noise value, peak value and correspondence thereof.
Phenomenon is experienced in test: when On-site Experience air-out is unstable, the test function of assembling prior art hears the Abnormal Sound that air-out inequality causes more significantly, and the testing machine Abnormal Sound of embodiments of the invention has larger improvement, distance test (DT) machine one meter of distance does not hear abnormal sound.
Concrete test data is as follows:
(1) low wind shelves:
(2) apoplexy shelves:
(3) high wind shelves:
(4) superelevation wind shelves:
From experiment, the air-conditioner air-conditioner more of the prior art noise of the present embodiment is low, and acoustical quality is also better.Owing to have employed said structure, one end that evaporator fin gap is minimum, the gap (gap A and clearance C) of the first and second snail tongues and through-flow fan blade is minimum, and when air-flow enters air-conditioner, air-flow is comparatively anxious, improves the intake of this end; One end that evaporator fin gap is maximum, first and second snail tongues maximum with through-flow fan blade gap (gap B and clearance D), when air-flow enters air-conditioner, air-flow comparatively relaxes, decrease the intake of this end, finally reach whole air channel air flow pressure consistent, the object that whole evaporimeter intake is consistent, final realization promotes evaporator heat exchange effect effectively, greatly improve condensation effect, reach the design object of the noise reducing air-conditioner and the tonequality improving air-conditioner simultaneously.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
