Detailed description of the invention
As shown in Figure 4, Figure 5, the evaporimeter of the first embodiment of the present invention comprises cooling coil 2 and cooling fins 1, wherein, cooling coil 2 comprises multiple comb group 21, angle is there is between adjacent comb group 21, make when viewed from the end of cooling coil, multiple comb groups 21 are arranged to the form of setback line.
By with the comb group 21 of the arranged in form cooling coil of setback line, its contour length can be reduced when ensureing that the effective length (i.e. length of run) of evaporimeter is enough, also namely, the reduction of contour length is obtained by making the size of evaporimeter in thickness become large.Like this, when evaporimeter is inclined and mounted on cabinet air-conditioner inside, space in machine (space namely above evaporimeter) can be utilized more than the tabular evaporimeter of prior art, but occupy less height space, thus also just contribute to the height dimension H reducing cabinet air-conditioner, and then reduce the volume of cabinet air-conditioner.
Because cooling coil is with the arranged in form of setback line, thus the effective length (i.e. length of run) of evaporimeter easily realizes the effective length (i.e. contour length) being greater than the tabular evaporimeter of prior art.Therefore, even if evaporimeter of the present invention adopts the width reduced, required heat exchange area (i.e. the product of effective length and width) can also still be ensured.So when air-conditioning power is certain, evaporimeter of the present invention can occupy space in less machine in width, thus also contribute to the width dimensions W reducing cabinet air-conditioner, and then reduce the volume of cabinet air-conditioner.
Preferably, as illustrated in figures 4-5, each comb group comprises multiple U-shaped pipe (in illustrated example being 6), and described multiple U-shaped pipe is arranged to row with misplacing successively.Such as, as shown in Figure 5, multiple U-shaped pipe is arranged to multilayer, and the U-shaped pipe of adjacent layer misses one another, and also namely partly overlaps, thus ensures the effect of heat exchange better.
Preferably, described multiple U-shaped pipe is arranged to every layer and comprises a U-shaped pipe.Certainly, every layer comprises plural U-shaped pipe is also feasible.
Preferably, each comb group comprises 3-8 layer U-shaped pipe, such as illustrated 6 layers.By arranging the difference of the number of plies, the profile thickness (i.e. the height of the ripple of setback line) of evaporimeter can be changed neatly, thus also just easily obtain required evaporimeter contour length.
Preferably, in each ripple of described setback line, there is identical height or different height at least partially.Correspondingly, the different parts of evaporimeter has identical or different U-shaped pipe arranging density.Such as, in embodiment as illustrated in figures 4-5, all ripples have identical height (number of plies of U-shaped pipe is identical).As required, the ripple also can being arranged to a part has identical height, and other ripple is then highly different; Or all ripples all have different height, such as, embodiment shown in Fig. 6-7.
As shown in fig. 6-7, the difference of the evaporimeter of the second embodiment of the present invention and the evaporimeter of the first embodiment is, the height of each ripple of its setback line increases successively or reduces successively.Also namely, when viewed from the side, evaporimeter presents stepped.
Preferably, the number of plies forming the U-shaped pipe comprised in the comb group of each ripple of differing heights is different.Also, namely, when ripple at least partially has differing heights, the number of plies forming the U-shaped pipe comprised in the comb group of these ripples is different.Such as, as shown in fig. 6-7, formed in the comb group of each ripple and comprise 6 layers, 5 layers, 4 layers and 3 layers of U-shaped pipe respectively.
In the first embodiment and the second embodiment, preferably, the outline of described cooling fins 1 is provided with the notch corresponding to the shape of described setback line, such as V-shaped groove mouth.The existence of notch can reduce the weight of evaporimeter, and can not have influence on heat exchange efficiency.
Preferably, described evaporimeter also comprises the side plate 3 of the end being positioned at cooling coil 2, the height dimension of described side plate 3 is consistent with the height dimension (i.e. the gauge of evaporimeter) of cooling fins 1, and does not comprise the notch corresponding to described setback wire shaped.Side plate 3 does not arrange notch and can cut down finished cost, and makes the good looking appearance of evaporimeter, avoids there is too much wedge angle etc., ensures the security used.
When the height of each ripple of the setback line of evaporimeter is different, the height dimension of the appropriate section of side plate 3 also changes thereupon, and such as, as described in Fig. 6-7, side plate 3 presents stepped equally.
Evaporimeter of the present invention is under the prerequisite ensureing higher heat transfer effect, length dimension and/or the width dimensions of reduction is obtained by increasing gauge, thus more reasonably make use of the inner space of cabinet air-conditioner, make when air-conditioning power is identical, compared with prior art, the size that can reduce cabinet air-conditioner during evaporimeter of the present invention is used.
Angle value between the adjacent comb group of evaporimeter of the present invention, the parameter such as the quantity of ripple, the height of ripple in setback line, all can arrange according to concrete operating mode, or the target size according to cabinet air-conditioner designs, to reach the inner space that can make full use of cabinet air-conditioner, the object reducing cabinet air-conditioner size.
The object of another aspect of the present invention is to provide a kind of cabinet air-conditioner, and it comprises aforesaid evaporimeter, as shown in Figure 8.Size due to this evaporimeter is less than the evaporimeter of prior art, thus when air-conditioning power is constant, cabinet air-conditioner of the present invention also correspondingly has the volume (height and/or width) of reduction.
Preferably, when this evaporimeter adopts the evaporimeter of second embodiment of the invention, also be, when the ripple at least partially of evaporimeter has differing heights, the height that described evaporimeter is mounted to be positioned at the ripple of top is greater than the height of the ripple being positioned at below, also namely, the part that the thickness of evaporimeter is large is positioned at top, thus is furnished with more U-shaped pipe on top.Like this, due to evaporimeter oblique installation in cabinet air-conditioner, wherein top is near the rear wall of cabinet air-conditioner, therefore when wind upwards blows from the centrifugal blower below cabinet-type air conditioner, bigger than normal near the air quantity on evaporimeter top, thus preferably arrange that on top more U-shaped pipe is to improve heat exchange efficiency.
Certainly, according to the concrete condition of cabinet air-conditioner, also can be arranged to the large part of the thickness of evaporimeter and be positioned at below, namely at the more U-shaped pipe of lower disposed.Such layout, also makes the center of gravity of evaporimeter lower.
In addition, in prior art, under the prerequisite meeting performance, the inner blower of cabinet air-conditioner adopts major diameter, slow-revving blower fan usually, to realize the target of low noise.And large diameter centrifugal blower also has larger fan blade height (i.e. axial dimension) usually, the thickness of cabinet air-conditioner is made to be difficult to further reduction thus.Therefore, the cabinet air-conditioner due to above-mentioned embodiment have employed the diameter fan 200 of prior art, and the thickness of cabinet air-conditioner is also difficult to further reduction.
To this, in another embodiment of the present invention, described cabinet air-conditioner comprises two centrifugal blowers 201 and 202 in parallel, as shown in Figure 9.Owing to adopting two centrifugal blowers, thus under the prerequisite ensureing air quantity, diameter and the fan blade height of each centrifugal blower all can reduce, and so just can reduce the gauge W of cabinet air-conditioner.
Preferably, two centrifugal blowers 201 and 202 arrange (as shown in Figure 9) up and down in cabinet air-conditioner, or arrange in diagonal angle, and also namely two centrifugal blower in the vertical directions exist dislocation.The mode of this dislocation, compared to arranging up and down, can reduce the size of height aspect, but can increase the size of width aspect.Which kind of is arranged in concrete employing, depends on the parameter such as the inside dimension of cabinet air-conditioner and the concrete size of blower fan.Certainly, when user to the requirement reduced in width dimensions lower than to (when such as using in height-limited space) when the requirement reduced in height dimension, two centrifugal blowers also can adopt horizontally disposed, like this, the width dimensions of cabinet air-conditioner becomes large, but height dimension can reduce greatly.Further, the width dimensions of evaporimeter also can increase along with the width dimensions of cabinet air-conditioner, and thus length dimension then can reduce, thus reduces the height dimension of cabinet air-conditioner further.
To sum up, cabinet air-conditioner of the present invention can meet the demand of user to small shell cabinet-type air conditioner.
