The specific embodiment
The specific embodiment below with reference to Fig. 4～6 pair cabinet air-conditioner described in the utility model is described in detail.
The housing 1 of cabinet air-conditioner consists of top board, panel 11, backboard 12, left plate 13, right plate 14 and base.Shown in Fig. 5, in the Liang Ge bight of housing 1 rear side (being left side plate and backboard junction), form respectively straight flange chamfering, be understood that, also straight flange chamfering can be replaced to arc angling shown in Fig. 6, make thus the cross section of housing 1 be formed by rectangular area A and chamfered area B.Similar with the structure of cabinet air-conditioner shown in Fig. 1, conventionally, in the interior receipts of housing 1, the heat exchanger 2 being obliquely installed is housed and is placed in the centrifugal fan below this heat exchanger 2.On panel 11, in the above and below of heat exchanger 2, be provided with air outlet 3 and return air inlet 4, and return air inlet 4 is oppositely arranged with centrifugal fan.In the bottom of heat exchanger 2, be provided with drip tray 5.
The heat exchanger 2 that receipts are contained in housing 1 is spliced by First Heat Exchanger 21 and the second heat exchanger 22, and wherein, the second heat exchanger 22 is positioned at the top of First Heat Exchanger 21.Take First Heat Exchanger 21 as example, First Heat Exchanger 21 comprises the first fin 211 of some thin-and-longs and the first heat exchanger tube 212 circulating for cold-producing medium, these a plurality of first fin 211 arrange along the left and right directions stack of housing 1, are provided with tactic a plurality of installation through hole along its length on single the first fin 211.The first heat exchanger tube 212 consists of the some straight tubes and the return bend that be arranged in parallel, these a plurality of straight tubes pass the installation through hole on the first fin 211 successively along left and right directions, and be communicated with adjacent straight tube by return bend, make cold-producing medium interior along roundabout reciprocal direction circulation at the first heat exchanger tube 212.In the First Heat Exchanger 21 left and right sides, be respectively equipped with the first tube sheet 213 in order to the first heat exchanger tube 212 and the first fin 211 are fixed together.In like manner, the second heat exchanger 22 has and the similar structure of First Heat Exchanger 21, in the second heat exchanger 22 both sides, is respectively equipped with the second tube sheet 223.
As shown in Figure 4, First Heat Exchanger 21 is all greater than the second heat exchanger 22 along the width on left and right directions and the height gone up along the vertical direction.The second heat exchanger 22 is with First Heat Exchanger 21 in same plane, and this second heat exchanger 22 arranges between two parties on First Heat Exchanger 21 top, and the two center line is overlapped.The second heat exchanger tube 222 of the second heat exchanger 22 is communicated with the first heat exchanger tube 212 of First Heat Exchanger 21, realizes cold-producing medium and circulates between First Heat Exchanger 21 and the second heat exchanger 22.On the inner surface of left plate 13 and right plate 14, be integrally formed respectively the first supporting plate 131 and the second supporting plate 141 that along the incline direction of heat exchanger 2, arrange, this first supporting plate 131 and the second supporting plate 141 are the tabular parts of strip.First Heat Exchanger 21 and the second heat exchanger 22 both sides are supported on respectively on the first supporting plate 131 and the second supporting plate 141, by screw (securing member), the first tube sheet 213 and the second tube sheet 223 are separately fixed on the first supporting plate 131 and the second supporting plate 141.The first supporting plate 131 and the second supporting plate 141 extend towards housing 1 inner side respectively and seal the gap between First Heat Exchanger 21 and the second heat exchanger 22 both sides and left plate 13 and right plate 14.
In addition, on the first supporting plate 131 and the second supporting plate 141, in First Heat Exchanger 21 and the second heat exchanger 22Xiang stitching portion, be provided with reinforcement, by this reinforcement, can improve the intensity corresponding to First Heat Exchanger 21 and the second heat exchanger 22Xiang stitching portion of the first supporting plate 131 and the second supporting plate 141, be conducive to improve the fixed stably solidity of heat exchanger 2.
As shown in Figure 5 and Figure 6, the stitching position of the second heat exchanger 22 and First Heat Exchanger 21 with chamfering the original position on left side plate corresponding, wherein, the width of First Heat Exchanger 21 is corresponding with the distance between the original position of two chamferings on left plate 13 and right plate 14; The width of the second heat exchanger 22 corresponding with the distance between the final position of two chamferings on backboard 12 (being the plane place width of backboard 12).The projected area of First Heat Exchanger 21 in the vertical directions covers rectangular area A, the projected area of the second heat exchanger 22 in the vertical directions covers chamfered area B, can increase the effective heat exchange area of heat exchanger 2, be conducive to improve the heat exchange efficiency of heat exchanger, thereby improve the ability of air-conditioning.
In addition, due to the gap between the first supporting plate 131 and the second supporting plate 141 sealing First Heat Exchangers 21 and the second heat exchanger 22 both sides and left plate 13 and right plate 14, improved the seal between heat exchanger 2 and housing 1, make the indoor gas being inhaled into by return air inlet 4 flow to housing 1 top by heat exchanger 2, and then drain into indoor via air outlet 3.Like this, can strengthen the mobility of heat exchanger 2 place, windward side gases, avoid gas by aforementioned gap, to flow to housing 1 top without crossing heat exchange, be conducive to improve the heat transfer effect of heat exchanger.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
For example, as shown in Figure 5 or Figure 6, in the Liang Ge bight of housing 1 rear side, form respectively straight flange chamfering or arc angling, now, the second heat exchanger 22 is near backboard 12 1 side settings.Yet not limited thereto, also backboard or panel directly can be formed to arc, the final position of symmetrically arranged two chamferings overlaps, now, the corresponding chord length that connects the string that two ends form of aforementioned arc of the width of the second heat exchanger.
Again for example, as shown in Figure 5 or Figure 6, at the rear side of housing 1, straight flange chamfering or arc angling are set, now, First Heat Exchanger 21 arranges near the front side of housing 1, and the second heat exchanger 22 is near the rear side setting of housing 1.Yet not limited thereto, for outward appearance or structure needs, also can straight flange chamfering or arc angling be set in the front side of housing, now, the setting position of First Heat Exchanger and the second heat exchanger exchanges; Or, at front side and the rear side of housing, straight flange chamfering or arc angling are all set, now, the second heat exchanger is separately positioned on top and the low side of First Heat Exchanger.In addition, also can straight flange chamfering or arc angling be set on left side and/or the right side of housing, now the set-up mode of heat exchanger and aforementioned similar.
Again for example, above-mentioned heat exchanger is not limited to First Heat Exchanger and the second heat exchanger, also can be provided with even the 4th heat exchanger of the 3rd heat exchanger that splices mutually with them, the projected area of the 3rd heat exchanger and/or the 4th heat exchanger in the vertical direction covers the region not covered by the second heat exchanger in chamfered area, and the projected area of in the vertical direction all covers chamfered area as far as possible.That is to say, aim of the present utility model is to protect the projected area of heat exchanger in the vertical direction to cover chamfered area, does not limit number and the shape of the heat exchanger of realizing this object.
