The specific embodiment
See also Fig. 1 to Fig. 6, in the utility model preferred embodiment, this high-effect machine cabinet air-conditioner 100 comprises having housing 1, be housed in vapour compression refrigeration system 3 in housing 1, and control the electrical equipment 5 of vapour compression refrigeration system 3.
Housing 1 comprises front panel 11, relative top board 10 and base plate 12, and a pair of relative side plate 13.Front panel 11 offers outer blower fan air outlet 110, and base plate 12 offers outer blower fan air inlet 120.Wherein side plate 13 offers inner blower air inlet 130 and inner blower air outlet 132 along the vertical direction.Dividing plate 14 becomes the first chamber (the cabinet outside) the 15 and second chamber (cabinet is inboard) 16 with housing 1 interior separation.
In the first chamber 15, it is provided with the diaphragm plate 151 of horizontal positioned and vertical perpendicular support 152, and the first chamber 15 is divided into upper chamber 153 and lower chambers 154.Wherein, be provided with tilted-putted condenser 2 in upper chamber 153, one main surface is relative with outer blower fan 6 on being installed in diaphragm plate 151, and another main surface is relative with outer blower fan air outlet 110.Outer blower fan 6 is axial flow blower, and its along continuous straight runs arranges, and carries out heat exchange from the surface that outer blower fan air inlet 120 is introduced extraneous air and condenser 2.The upper and lower chamber 153 of sealing, 154 deep bead 155 also are installed in upper chamber 153, thereby form the swapace of sealing.The pipeline assembly 8 that compressor 4 is installed on base plate 12 in lower chambers 154 and is connected with condenser 2, evaporimeter 3, compressor 4 is to form complete vapour compression refrigeration system 3.
The second chamber 16 tops, inner blower 7 is axial flow blower, it is along with outer blower fan 6, the vertical direction setting of perpendicular direction being set.Inner blower 7 is installed on side plate 13, and aligns with the inner blower air inlet 130 that is opened on side plate 13.The bottom of the second chamber 16 is tiltedly installed with the evaporimeter 3 that is communicated with above-mentioned pipeline assembly 8, and the main surface of one and the inner blower air outlet 132 that is opened on side plate 13 align.Evaporimeter 3 be obliquely installed direction and condenser 2 to be obliquely installed direction mutually vertical.In order to satisfy under cryogenic conditions, keep cabinet temperature higher than the outer temperature of cabinet, also to assist and be provided with heater 9, it is between evaporimeter 3 and another side plate 13, and the edge direction opposite with condenser 2 incline directions placed.
In order to improve heat exchanger effectiveness, evaporimeter 3 and the condenser 2 of the high-effect machine cabinet air-conditioner 100 of the utility model improve.Condenser 2 is similar with evaporimeter 3 structures, be pipe type heat exchanger, therefore only be introduced as an example of condenser 2 example: see also Fig. 7 to Fig. 9, in conjunction with Fig. 1 to Fig. 6, condenser 2 has many U-shaped pipes 21, connects the U-shaped pipe joint 23 of U-shaped pipe 21, and is arranged in the some parallel radiating fin 22 of U-shaped pipe 21 outsides.U-shaped pipe 21 is for increasing the shape structure, make condenser 2 have more long and narrow structure, it is larger and short transverse (the main bearing of trend of the radiating fin 22) size decreases of lengthwise dimension (the main bearing of trend of U-shaped pipe 21), so under identical main pipe rail length, the quantity of U-shaped pipe 21 and U-shaped pipe joint 23 reduces, and provides cost savings and has improved packaging efficiency.Simultaneously, reduced because fluid is roundabout in pipeline the local resistance that brings because of 21 bendings of U-shaped pipe when mobile, also improved heat exchange efficiency.The ratio of condenser 2 length directions (the main bearing of trend of U-shaped pipe 21) and short transverse (the main bearing of trend of radiating fin 22) is at least greater than 1.Long and narrow configuration is not limited to tube-fin condenser 2 and/or evaporimeter 3, and it can also be applied to corrugated tube type and parallel flow type.Radiating fin 22 is roughly vertical with the bearing of trend of U-shaped pipe 21 to be arranged and is parallel to each other.Each radiating fin 22 offers and can hold some row's U-shaped pipes 21 and wear the manhole 221 that some rows of passing through arrange along the vertical direction.In order to improve heat exchanger effectiveness, radiating fin 22 is for fenestration designs, and its punching has some heat radiation window groups 223.Each heat radiation window group 223 and through hole 221 intervals settings are the H shape of horizontal positioned, and offer along the vertical direction some windows different in size 2230 to improve radiating efficiency.Take the center line of through hole 221 as the boundary, the window 2230 of both sides be obliquely installed and opening direction opposite.
Special needs to be pointed out is, in the utility model specific embodiment only with this high-effect machine cabinet air-conditioner 100 as example, the equal principle that discloses of applicable the utility model of the high-effect machine cabinet air-conditioner of other types in actual applications.For the person of ordinary skill of the art, that does under instruction of the present utility model changes for equivalence of the present utility model, must be included in the scope that the utility model claim advocates.
