Description
Technical field
The present invention relates to the technical field of air-conditioning in the electric equipment, be specifically related to a kind of air-conditioner outdoor unit, belong to the improvement technology of air-conditioner outdoor unit.
Background technology
The air-conditioning product turn to the frequency conversion direction from constant speed at present, characteristics such as the convertible frequency air-conditioner product is energy-conservation, and cooling and warming speed is fast, and temperature homogeneity is good are by user's well recognized.But the automatically controlled plate of the off-premises station of transducer air conditioning has been covered with a lot of large power electric control devices, can produce a large amount of heats during these large power electric control device work, and thus, the heat dissipation problem of automatically controlled device becomes the great technical barrier that the convertible frequency air-conditioner product must solve.The bad automatically controlled device temperature that causes easily of dispelling the heat rises too high, and causes control panel and frequency converter poor work stability, and shorten service life, influences the quality and the cost performance of product.
Automatically controlled device (6) cooling system of general frequency conversion off-premises station is to cool off with the air-flow through condenser (3) on the market; Of Fig. 1; Arrow among Fig. 1 is an airflow direction; Because condenser itself also is a heat dissipation equipment, the temperature through the air-flow behind the condenser can raise, so heat exchange efficiency is not high.Particularly under the environment of outdoor high temperature, the automatically controlled device operating temperature is very high, is badly in need of heat radiation, but this moment, condenser was strengthened heat release equally, can be higher more than 20 ℃ through the gas flow temperature behind the condenser than natural airflow, be unfavorable for that more the heat of automatically controlled device distributes.
Can find out that from the basic calculating formula-Newton's law of cooling of convection transfer rate the hot-fluid of convection heat transfer' heat-transfer by convection is directly proportional with their temperature difference between fluid and the solid wall surface, that is:
Q?=?h*A*(t
w-t
∞)
In the formula:
T
w, t
∞Be respectively the temperature of the surface of solids and fluid, unit K;
A is the wall area, the m^2 of unit;
Q is the heat transfer on the area A, the W of unit;
H is called surperficial convective heat-transfer coefficient, the W/ of unit (m^2.K).
Summary of the invention
The objective of the invention is to propose a kind of air-conditioner outdoor unit that improves the radiating effect of air-conditioner outdoor unit automatically controlled device to above-mentioned problem.
In order to achieve the above object; The technical scheme that the present invention takes: a kind of air-conditioner outdoor unit, comprise the off-premises station main body, be provided with fan and condenser in the said off-premises station main body; Condenser places the rear side of fan; Form the air-flow cavity between condenser and the fan, also be provided with wind channel tube in the said off-premises station main body, the exterior of the air intake of the set hollow cavity of wind channel tube and air-flow cavity; The gas outlet of the set hollow cavity of wind channel tube communicates with the air-flow cavity, and the automatically controlled device of air-conditioner outdoor unit is installed in the set hollow cavity of wind channel tube.
Direct and the air-conditioner outdoor unit external communications of the air intake of the set hollow cavity of above-mentioned wind channel tube.
Also be provided with the accommodating chamber that is used to settle compressor in the above-mentioned off-premises station main body, accommodating chamber places the outside of air-flow cavity, and the air intake of hollow cavity is communicated with accommodating chamber.
Also be provided with dividing plate in the above-mentioned off-premises station main body, air-flow cavity and accommodating chamber lay respectively at the both sides of dividing plate.
Above-mentioned wind channel tube is installed on the dividing plate, and the gas outlet of the hollow cavity that wind channel tube is set and air intake lay respectively at the both sides of dividing plate.
The gas outlet of above-mentioned hollow cavity is towards a side of fan.
The present invention is through installing wind channel tube in the off-premises station main body; And be installed in the automatically controlled device of air-conditioner outdoor unit in the set hollow cavity of wind channel tube, during off-premises station work, the radiating airflow of automatically controlled device is directly introduced from the outside of the air-flow cavity between condenser and the fan through wind channel tube; Because passing the radiating airflow of wind channel tube hollow cavity is not pass through condenser; So the temperature of this radiating airflow near natural temperature, has increased the temperature difference of automatically controlled device and radiating airflow, reaches the effect that strengthens heat exchange; Thereby improved the stability of automatically controlled device work, promoted the quality and the cost performance of product; Under the situation that identical heat exchange requires, also can reduce the automatically controlled device radiator area, reduce product cost.

Fig. 3 is the wind channel tube structural representation of air-conditioner outdoor unit of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
The structure of air-conditioner outdoor unit of the present invention comprises off-premises station main body 1 like Fig. 2, shown in 3, is provided with fan 2, condenser 3, automatically controlled device 6, wind channel tube 4 in the off-premises station main body 1; Its fan 2 is fixed in the off-premises station main body 1 with condenser 3, and condenser 3 places the rear side of fan 2, and forms air-flow cavity 5 between condenser 3 and the fan 2; The position that is positioned at air-flow cavity 5 outsides in the said off-premises station main body 1 also is provided with the accommodating chamber 7 that is used to settle compressor, and air-flow cavity 5 and accommodating chamber 7 separate through dividing plate, and air-flow cavity 5 and accommodating chamber 7 lay respectively at the both sides of dividing plate; Said wind channel tube 4 is installed on the dividing plate, and the gas outlet 411 of wind channel tube 4 described hollow cavities 41 is positioned at that side that dividing plate is provided with air-flow cavity 5, and gas outlet 411 is communicated with air-flow cavity 5; The air intake 412 of hollow cavity 41 is positioned at that side that dividing plate is provided with accommodating chamber 7; And air intake 412 is communicated with accommodating chamber 7, perhaps air intake 412 directly and the air-conditioner outdoor unit external communications, in addition; In order to reach best current rate; In the present embodiment, the gas outlet 411 of hollow cavity 41 is towards a side of fan 2, and above-mentioned automatically controlled device 6 is installed in the wind channel tube 4 described hollow cavities 41.
When air-conditioner outdoor unit of the present invention is worked; When fan 2 rotates; Air pressure in the air-flow cavity 5 can be lower than the air pressure of air-flow cavity 5 outsides; Air-flow cavity 5 outside a part of air-flows can pass condenser 3 surfaces and enter in the air-flow cavity 5, and air-flow cavity 5 outside another part air-flows can get into the hollow cavity 41 of wind channel tube 4 from the air intake 412 of wind channel tube 4, and automatically controlled device 6 surfaces of passing in the hollow cavity 41 that is contained in wind channel tube 4 enter in the air-flow cavity 5 from gas outlet 411 again; All air-flows that accumulate in the air-flow cavity 5 are drawn out to the air-conditioner outdoor unit outside by fan 2 at last, and the arrow among Fig. 2 is an airflow direction.The air-flow that sucks owing to the air intake 412 from hollow cavity 41 is directly to obtain from accommodating chamber 7 or air-conditioner outdoor unit outside; So the temperature of the air-flow before sucking is near natural temperature; Increase the temperature difference of radiating airflow and automatically controlled device 6, thereby reached the effect that strengthens heat exchange.
