Abstract
The invention discloses a structure of an outdoor unit of a commercial air-conditioner. The baffle which is used for separating the setting spaces of a condenser, a control box and the like, is provided with an air guide cover which comprises an air outlet guide way at the upper part of the baffle and an air inlet guide way at the lower part of the baffle; the air outlet guide way and the air inlet guide way are communicated with each other by an opening of the baffle; the air outlet guide way is fixed to the baffle by screws and the air inlet guide way is fixed to the baffle by welding. By arranging the air inlet and outlet guide ways on the baffle, the outdoor unit of the air-conditioner facilitates taking away the hot air around the printed circuit board inside the electric appliance control box by a fan, so as to adequately cool down the cooling fin, prolong the service life of the printed circuit board and decrease various accidents arising from high temperature.
Description
Technical field
The present invention relates to a kind of commercial air conditioner off-premises station, particularly relate to the baffle arrangement of commercial air conditioner outdoor unit.
Background technology
Air-conditioning is a kind of device that makes its inner refrigerant carry out the refrigeration of being made up of compression process, condensation process, expansion process and evaporation process or heat circulation.When air-conditioner carries out kind of refrigeration cycle, the refrigerant that becomes high-temperature high-pressure state through compressor compresses can flow to condenser under the guiding of cross valve, and in condenser, dispel the heat to the outside, when flowing through expansion valve, significantly reduce its temperature and pressure then, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter subsequently, flow back in the compressor again through fluid reservoir at last.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.It is then opposite with above-mentioned kind of refrigeration cycle process to heat circulation.
Air-conditioning is divided into domestic air conditioning and business air conditioner usually.Wherein business air conditioner mainly is used in the buildings such as office building, market.The commercial air conditioner outdoor unit of prior art comprises: as shown in Figure 1, constitute the housing of off-premises station front panel 2, top panel 4, rear board 10, two side panels 11, the chassis 1 that is arranged on lower part of frame and each parts can be installed thereon, at least one is arranged on top one side on chassis 1, the low-temp low-pressure gaseous coolant can be compressed into the compressor 15 of HTHP gaseous coolant, and front panel is provided with grid 3, and rear board is provided with grid 9; Discharge grid 7 at the top top panel; After connecting power supply, can produce the fan electromotor of rotary power, link to each other with the output shaft of fan electromotor is anterior, thereby can under the revolving force effect of fan electromotor, rotate, thereby with extraneous air from the housing front panel grid 3 and the inside that is drawn into housing of the grid 9 on the rear board and the air that will carry out heat exchange with condenser 8 air discharge grille 7 rows from the housing top panel to the outdoor fan 17 of the exterior space; Be arranged between compressor 15 and condenser 8 and the outdoor fan 17, be used to separate the baffle plate 12 that compressor 15 and condenser 8 and outdoor fan 17 are provided with the space; The control box 14 that electric elements etc. are installed is arranged below baffle plate 12, and radiator fan 13 dispels the air of the heat around the control box.But, there is following point in the air-conditioner outdoor unit of this prior art: as mentioned above, owing to discharge the top that fan is installed in outdoor set cabinet, the middle part has again and separates the baffle plate that prevents the condensed water that drips from condenser, therefore the air that is unfavorable for the heat that printed circuit panel area electric elements produce distributes, thereby influence service life of printed circuit board (PCB), electric elements, even cause line short and cause and accident such as fire make the off-premises station cisco unity malfunction.
Summary of the invention
Technical problem to be solved by this invention is, forms the wind path passage around control box, makes the air of the heat that electric elements produce effectively discharge the off-premises station outside.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: constitute off-premises station and be provided with the top panel of discharging grid, the front and back panels that has grid, side panel, the housing on chassis, outdoor machine fan, condenser, compressor, fluid reservoir, control box and take away hot blast around the control box radiator fan, separate the baffle plate 12 that compressor and condenser and outdoor fan are provided with the space; Be provided with air-out guide passage 18, in the baffle plate bottom air intake guide passage 19 be installed on described baffle plate 12 tops, air-out guide passage 18 and air intake guide passage 19 are by opening 20 UNICOMs of baffle plate 12.
Described air-out guide passage 18 is cover bodies of the lateral opening above the opening 20 of baffle plate 12.
Described air intake guide passage 19 is below the opening 20 of baffle plate 12, has two side nations 26, both sides respectively with the cylindrical shell of coaming plate 27 welding, interface one side also has a upwards outer 24 of folding on the described air intake guide passage, this outer 24 is close on the baffle plate 12.
Described air-out guide passage 19 is fixing by screw and baffle plate 12, and air intake guide passage 19 is fixing with baffle plate 12 welding.
The invention has the beneficial effects as follows: the air of the heat that will be produced by electric elements around the control box with axial-flow fan by air guide structure is taken off-premises station out of, fin is cooled off fully, increase the service life of printed circuit board (PCB), reduced the various accidents that cause owing to the printed circuit plate temperature is too high.
