As shown in fig. 1, the air duct structure of the air cooler of the present invention includes an air duct body 1 and a fan 2 disposed in the air duct body 1, the air duct body 1 includes an air inlet section and an air outlet section which are communicated with each other, an air inlet of the air inlet section is adapted to an evaporator 3, the air outlet section is in a bell mouth shape, and an inner diameter of the air outlet section is gradually increased from one end close to the air inlet section to the other end; the middle part in the air outlet section is fixedly provided with a box body 4, the fan 2 comprises a first motor 21 and an impeller 22 arranged on a rotating shaft of the first motor 21, the first motor 21 is positioned in the box body 4, the rotating shaft of the first motor 21 extends towards one side of the box body 4 close to the air inlet section, and the impeller 22 is correspondingly positioned at the joint of the air inlet section and the air outlet section; still be equipped with second motor 5 in the box body 4, the rotation axis of second motor 5 extends to the air outlet direction of air-out section, and is equipped with air-out grid 6 in the axis of rotation of second motor 5 cover. The utility model has reasonable structural arrangement, stable fixing mode, large wind speed of the sent cold air and convenient diffusion to the periphery, thereby accelerating the circulation of indoor air refrigeration.
In the practical application of the utility model, the air duct body 1 is designed in a sectional manner, so that the air duct body is convenient to manufacture and can be fixed by welding, the air inlet section is arranged according to the shape of the evaporator 3, the evaporator 3 covers most of the area of the air inlet section, the fan 2 in the air duct body generates negative pressure, and cold air formed after passing through the evaporator 3 advances along the air duct body 1 and is difficult to generate backflow. The fan 2 is arranged in the air outlet section, a box body 4 is fixedly arranged in the air outlet section to load a first motor 21 of the fan 2 and a second motor 5 of the air outlet grille 6, and the box body 4 can be connected with the inner wall of the air outlet section to fix the box body 4 by reserving screw holes at the periphery of the box body 4 and fixing support bars through screws; or the bottom of the box body 4 is a downward convex installation part, a support rod is inserted in the installation part, the two ends of the support rod are connected with the inner wall of the air outlet section, and the installation can be realized as long as the width of the support rod is enough. Just so can erect fan 2 in wind channel body 1, and can not influence the impeller 22 rotation of fan 2 and form inside negative pressure, simultaneously because box body 4 is located wind channel body 1's air-out section middle part, and the air-out section is the horn mouth form, the cold wind that impeller 22 drove will receive the influence of air-out section shape and the blockking of box body 4 and hug closely the inner wall and spread forward, can not concentrate in the middle part and be difficult to adjust its air-out direction, cooperation air-out grid 6 can form circulation cold wind, make indoor rapid cooling.
In one embodiment, the minimum diameter of the air outlet section is smaller than the height of the air inlet section, the air outlet section is connected to the middle of the air inlet section, and the length of the air outlet section is 1-1.5 times that of the air inlet section. The specification design of air-out section and air inlet section makes more concentrated behind the cold wind entering air-out section, and impeller 22 is located the handing-over department of air-out section and air inlet section, just blows off concentrated cold wind with higher speed, and the cross-section in here space narrows down suddenly moreover, changes in forming great negative pressure, and then accelerates the cold wind velocity of flow. Further, the minimum inner diameter of the air outlet section is 1.1-1.2 times of the maximum diameter of the impeller 22. Impeller 22 is close to with the inner wall of air-out section as far as possible, but will leave certain clearance, reserves impeller 22's rocking.
In one embodiment, the inclination angle alpha of the opening of the cross section of the air outlet section is 15-20 degrees. The design of this angle makes the air-out section can effectively guide cold wind by progressively expanding the scope of blowing off, and the cooperation box body 4 blocks, and under the effect of the expansion of this inclination, the air-out section cross-sectional area of horn mouth form does not increase to guarantee that the wind speed accelerates and is stable.
In one embodiment, the bottom of the air inlet section is also provided with a supporting plate 7, and the supporting plate 7 is provided with a buckle fixed with the air inlet section. The whole air duct body 1 is mainly clamped and fixed with the supporting plate 7 through the air inlet section, therefore, the air inlet section can be set to be in a cuboid shape, the edge of the air inlet section is convenient to be buckled and stressed with the hook-shaped buckle, and the air outlet section is 1-1.5 times as long as the air inlet section, so that even if heavier equipment such as a fan 2 is installed in the air outlet section through the stress of the air inlet section, the air outlet section can be stably fixed on the supporting plate 7. The layer board 7 mainly carries out fixed connection with the position that the air inlet section is close to the air-out section, and further, all leaves the space between the bottom edge of air inlet section and the evaporimeter 3 and between layer board 7 and the evaporimeter 3 bottom, and layer board 7 corresponds one side below that evaporimeter 3 kept away from wind channel body 1 and is equipped with flow distribution hole 71, and flow distribution hole 71 is used for assembling and shunting the comdenstion water. The rear end of the air inlet section and the corresponding position below the evaporator 3 are easy to cool water vapor in the air to form condensed water because the evaporator 3 cools the sucked air, and the condensed water can be quickly treated by the reserved gap and guided into the shunting hole 71, and the condensed water is prevented from being stranded or gathered on the supporting plate 7 by shunting.
In one embodiment, in order to avoid the condensed water from being accumulated, the supporting plate 7 is provided with an inclined plate 73, the inclined plate 73 is obliquely arranged from the bottom edge of the air inlet section to the flow dividing hole 71 from top to bottom, and a water absorption cotton cloth 72 is laid below the flow dividing hole 71.
