Abstract
The utility model discloses an air discharging structure of an axial fan of an outdoor unit, which comprises an outdoor unit casing, an outdoor unit fan, a condenser, a compressor and a printed circuit board, wherein the outdoor unit fan and the condenser are arranged in the casing; the compressor is connected with the condenser; the printed circuit board controls an outdoor unit to operate; skirt plates for air direction diversion are arranged on the periphery of the outdoor unit fan in the outdoor unit casing; the skirt plates form a circular arc shape and are formed on the upper side and the lower side of the outdoor unit fan around the outdoor unit fan; the skirt plates are respectively arranged on an upper panel and a lower panel in the outdoor unit casing. In the air discharging structure of an axial fan of an outdoor unit of the utility model, because air discharging paths formed by the skirt plates are arranged on the peripheries of blades of the fan, the flowing directions of wind generated by the rotation of the fan are centralized, and the wind can be discharged outside the casing directly. Therefore, the utility model can make the fan quickly discharge wind along the circular wind discharging paths and carry away heat generated by the condenser so that the condenser of the outdoor unit of an air conditioner condenses air quickly and has good heat dissipation effect.
Description
Technical field
The utility model relates to a kind of air-conditioner outdoor unit, particularly relates to a kind of air draft and concentrates good heat dissipation effect, the air discharge structure of the off-premises station aerofoil fan of rapid heat dissipation.
Background technology
Usually air-conditioning is made up of heater, refrigeration machine, clarifier etc., can or purify for room air refrigeration or heating, for the user creates suitable indoor environment.
If classification substantially, air-conditioning can be divided into separation type air-conditioning and integral air conditioner.Separation type and one-piece typely have an identical function.The separation type air-conditioning is provided with the indoor set with cooling/heat release in the indoor, the off-premises station with heat release/cooling and compressor is set in the outside, and links off-premises station and indoor set with the refrigerant pipe.Be arranged on and be provided with condenser (outdoor heat converter) and compressor in the outdoor off-premises station, be arranged in the indoor indoor set, be provided with evaporimeter (indoor heat converter).
Fig. 1 is the schematic diagram of common off-premises station.As shown in Figure 1, common off-premises station 10 has the housing 1 of hexahedral shape.Have peristome 14 on the front plate 12 of housing 1, the inboard of peristome 14 is provided with radiator fan.
In addition, as shown in Figure 2, the inside of housing 1 is provided with compressor 4 and condenser 5.Compressor 4 compresses the refrigerant that gasifies after indoor set and room air heat exchange.In the condenser 5, be compressed into the refrigerant of high-temperature high-pressure state,, liquefy by heat exchange.Form air-flow through outdoor machine fan again, allow air flow to outflow by peristome.During airflow passes condenser 5, can allow the refrigerant heat release of the condition of high temperature.
But, in the off-premises station of existing air-conditioning outdoor machine fan not being provided with air exhaust passage, the wind direction that the fan rotation produces is not concentrated, direction is bad, can not be discharged to the outside of housing by the very fast heat with in the housing, so cause the condenser heat radiation not rapid, radiating effect is bad.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of air draft to concentrate good heat dissipation effect, the air discharge structure of the off-premises station aerofoil fan of rapid heat dissipation.
The technical scheme that the utility model adopted is: a kind of air discharge structure of off-premises station aerofoil fan, include outdoor set cabinet, be arranged on the printed circuit board (PCB) of outdoor machine fan, condenser, the compressor that is communicated with condenser and the running of control off-premises station in the casing, the periphery that is positioned at outdoor machine fan in outdoor set cabinet is provided with wind direction water conservancy diversion deflector.Described deflector is an arc-shaped structure.Described deflector is formed on its both sides up and down around outdoor machine fan.Described deflector is separately positioned on the interior upper and lower panel of outdoor set cabinet.
The air discharge structure of off-premises station aerofoil fan of the present utility model owing to be provided with the wind output channel that is formed by deflector at the periphery of the flabellum of fan, makes the flow direction of the wind that the fan rotation produces concentrated, can directly arrange and guide to hull outside.So the utility model can make fan along the rapid air draft in circular air channel, and takes away the heat that condenser produces, make the condensation of condenser of air-conditioner outdoor unit rapid, radiating effect.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, describe the air discharge structure of off-premises station aerofoil fan of the present utility model in detail.
As shown in Figure 3, the air discharge structure of off-premises station aerofoil fan of the present utility model includes outdoor set cabinet 1, and the inside of housing 1 is provided with compressor 4, the condenser 5 that is communicated with compressor 4 and outdoor machine fan 2, and the printed circuit board (PCB) 3 of control off-premises station running.Wherein, compressor 4 compresses the refrigerant that gasifies after indoor set and room air heat exchange; The outdoor machine fan 2 that is arranged in the casing 1 forms air-flow, allows air flow to outflow by the peristome of outdoor set cabinet 1; Be compressed into the refrigerant of high-temperature high-pressure state, in condenser 5, carry out heat exchange when flowing through condenser 5, make the refrigerant heat release of the condition of high temperature, liquefy by outer gas stream.The periphery that is positioned at outdoor machine fan 2 in outdoor set cabinet 1 also is provided with wind direction water conservancy diversion deflector 6.
As mentioned above, be provided with the wind direction water conservancy diversion with deflector 6 by periphery at outdoor machine fan 2, the discharge air flow that has improved outdoor machine fan 2 to, can make outdoor machine fan 2 along the rapid air draft in circular air channel, the condenser 5 of off-premises station is dispelled the heat rapidly.
