Abstract
The utility model discloses an outdoor machine of an air conditioner. Ventilating windows aiming at a root of an internal heat radiator are added at a shell of the outdoor machine, so as to change the problem that a convection air negative-pressure area is formed at the root of the internal heat radiator, increase the heat-radiating efficiency of the heat radiator with a conventional structure, and simultaneously avoid the increment of the manufacturing cost of the heat radiator and the running noise of a fan. The outdoor machine of the air conditioner comprises a shell formed by connecting a top cover, a front panel, a back panel and a side plate with a bottom plate, and the front panel is provided with an air ring for ventilating. A plurality of ventilating windows are arranged at positions corresponding to the root of the internal heat radiator on one side of the air ring on the front panel. The ventilating windows are arranged at the positions on the front panel near the root of the heat radiator; the heat absorbed by the root of the heat radiator can be effectively exhausted in time from the ventilating windows; the convection negative-pressure area at the root of the heat radiator is changed; and the potential safety hazard of the abnormal temperature rise of a circuit board caused by difficult heat radiation is effectively solved.
Description
Technical field
The utility model is the improvement of carrying out at the air conditioner outdoor shell surface texture, in the hope of improving the heat dissipation ventilation efficient at the base regions of enclosure interior radiator, belongs to household electrical appliance technical field.
Background technology
At present the off-premises station of family expenses or commercial use air conditioner is taked various ventilation heat abstractors at large, and reason is that appliance controling element such as off-premises station circuit board can produce bigger heat in the course of the work.
For example, the control module of existing air-conditioner outdoor unit generally adopts the mode of radiator and circuit board close fit, and module board is installed near position, off-premises station air channel, and the convection current that utilizes fan running to produce is taken away the heat around the module board.The housing of existing off-premises station, its front panel part (particularly corresponding to heat sink location) except that solar or lunar halo is sealed, and easily forms the negative pressure region of convection current air thus in the junction of radiator and circuit board, and this part heat is difficult to timely discharge.
The common settling mode that improves above-mentioned module board radiating efficiency is to strengthen the radiator volume, increase the convective region area, improve fan running power or change this body structure of radiator the convection current air is introduced the radiator base portion of fin inside.But the cost of such scheme is bigger, not only directly has influence on the radiator manufacturing cost, and correspondingly causes the raising of fan running noise.
In view of this, the special present patent application that proposes.
The utility model content
Air-conditioner outdoor unit described in the utility model, its purpose of design is to solve problem that above-mentioned prior art exists and increases ventilation window at the Inner heat sink base portion at the outdoor shell place, to change the problem that this subregion forms convection current air negative pressure district, increase the radiating efficiency of existing structure radiator, the raising that the while is avoided radiator manufacturing cost and fan running noise again.
For realizing above-mentioned purpose of design, described air-conditioner outdoor unit mainly includes:
By the housing that top cover, front panel, rear board, side plate and base plate connect and compose, plate is provided with the solar or lunar halo that is used to ventilate in front.
The difference with the prior art part is that the position of one side of the solar or lunar halo on the plate, corresponding housing Inner heat sink base portion is provided with several ventilation windows in front.
As above-mentioned basic scheme feature, in the limited inner space of off-premises station, the radiator of existing volume and fan running convection type are difficult to satisfy circuit board and are rapidly heated and the too high problem of temperature rise.Press this patent design concept, plate is offered ventilation window near the position of radiator base portion in front, the heat that can effectively the radiator base portion be absorbed is discharged from ventilation window in time, change convection current negative pressuren zone herein, solved the potential safety hazard that causes the circuit board overheating because of the difficulty of dispelling the heat effectively.
Comparatively preferred improvement project is that described ventilation window is groove or shutter.
Further refinement mode at shutter is, several shutters are arranged in order from top to bottom along vertical, and arrangement mode can improve the through-rate of convection current air regularly, to improve radiating efficiency.
For the circuit board waterproof demand that satisfies the radiator base portion, avoid because of potential safety hazards such as ponding cause that circuit board is short-circuited, described several shutters, its window flanging are up and recessed to off-premises station inside.The window flanging up and recessed to inside also can prevent to interfere mutually with the external fan cover simultaneously.
As mentioned above, the advantage and the beneficial effect that have of the utility model air-conditioner outdoor unit is:
1, can directly improve the ventilation and heat efficient of radiator base portion, form convection current air negative pressure district and the unusual problem that heats up of circuit board that causes with therefore zone, the holding circuit plate normally moves and improves its service life;
2, do not change existing heat spreader structures and volume, when improving radiating efficiency, avoid the raising of radiator manufacturing cost and fan running noise;
3, less for the improvement of outdoor shell, do not influence existing mold and manufacturing process, off-premises station complete machine manufacturing cost does not improve.

Extremely shown in Figure 5 as Fig. 1, top cover 1, circuit board 2, radiator 3, dividing plate 4, front panel 5, fan guard 6, fan 7, solar or lunar halo 8, groove 9, shutter 10.
Grid lines among Fig. 2 and Fig. 3 is the signal that easily forms convection current air negative pressure district.
The specific embodiment
Embodiment 1, and to shown in Figure 5, described air-conditioner outdoor unit comprises the housing that is connected and composed by top cover 1, front panel 5, rear board, side plate and base plate (not shown) as Fig. 1.Wherein,
As shown in Figures 2 and 3, existing outdoor shell is easy to shown in the grid lines, because fan 7 is rotated counterclockwise, form a negative pressuren zone between solar or lunar halo 8 parts of radiator 3, dividing plate 4 and front panel 5, the thermal current of this intra-zone forms eddy current and is difficult to discharge, and promptly the heat of radiator base portion is difficult to shed.
Solution to this present embodiment is, the position of solar or lunar halo 8 one sides on the plate 5, corresponding housing Inner heat sink 3 base portions is provided with several ventilation windows in front, and ventilation window both can have been taked groove 9, also can take the structure of shutter 10.
Groove 9 or shutter 10 are positioned at the base position of radiator, can change negative pressuren zone herein effectively, form effective cross-ventilation, the operating temperature of circuit board 2 can be reduced the 5-6 degree.
