Description

Air circulation mechanism of air cooler

technical field

The utility model relates to the technical field of air coolers, in particular to an air circulation mechanism of an air cooler.

Background technique

In the hot season, people generally choose air conditioners as the preferred cooling tool. However, air conditioners consume a lot of power and are expensive to use, so most people choose air conditioners with good cooling effects instead of air conditioners. The basic working principle of the air cooler is: a wet curtain is formed on the air inlet side of the fan. When the inhaled air passes through the wet curtain, it exchanges heat with the refrigerant flowing through the wet curtain to cool down, and then can blow out a relatively low temperature airflow. Gives a sense of comfort. At present, the air inlet of the existing air cooler is usually set on the back of the machine body, and the air outlet is set on the front of the machine body. Because the cross-sectional area of the air inlet is small and the air intake is limited, it is difficult to maintain the stable high-speed operation of the fan, resulting in the air cooler. The wind speed of the air outlet is limited, and the overall cooling effect is not good.

Further, a partition for isolating the air outlet and the second air inlet is connected to the inner side of the front panel.

Further, the second air inlet includes a plurality of slots arranged on the front panel, and the inner surface of the front panel also protrudes inward to form a convex baffle that blocks the slots, and the convex baffle The upper side forms an opening opening upward at a position higher than the slot hole.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail. It should be understood that the following exemplary embodiments and descriptions are only used to explain the utility model, not as a limitation to the utility model, and, in the case of no conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

As shown in FIGS. 1 to 6 , an embodiment of the present invention provides an air circulation mechanism of a cooling fan, including a casing 3 and a fan 1 disposed inside the casing 3 .

The front panel 21 of the housing 3 is provided with an air outlet 23, the back or side of the housing 3 is provided with a first air inlet 27, and the front panel 21 is also provided with an air outlet 23 in the width direction of the front panel 21. Second air inlets 22 arranged side by side and isolated from each other.

A U-shaped air duct (shown by a U-shaped arrow in FIG. 3 ) is formed inside the housing 3 around the impeller 12 of the fan 1, and the second air inlet 22 and the air outlet 23 are respectively located at the The air inlet end and the air outlet end of the U-shaped air duct, the first air inlet 27 communicates with the middle section of the U-shaped air duct.

In the embodiment of the utility model, by adding the second air inlet 22 on the front panel 21, the area of the air inlet can be effectively increased, and a larger air inlet volume can be obtained, which can help the fan 1 to output the maximum power stably, and the wind speed of the cold air blown out can also be reduced. It can be greatly improved. Compared with the existing products on the market, the utility model can set more wind speed gears with higher wind speed, which can effectively improve the cooling efficiency of the air cooler.

In one embodiment of the present utility model, a partition 26 for isolating the air outlet 23 and the second air inlet 22 is also connected to the inner surface of the front panel 21, and the second air inlet 22 and the air outlet 23 are connected to each other. Isolation allows the two to work independently without interfering with each other.

In an optional embodiment of the present utility model, the fan 1 includes a motor 11 and an impeller 12 . The fan drives the impeller 12 to rotate at high speed through the motor 11, forming a negative pressure at the air inlet of the cooling fan, so that the air outside the cooling fan flows into the inside of the cooling fan, and flows along the U-shaped air duct under the action of the impeller 12.

In an optional embodiment of the present utility model, the second air inlet 22 includes a plurality of slots 221 arranged on the front panel 21, and the inner surface of the front panel 21 also protrudes inward to cover the slots. The convex baffle 222 of the hole 221 , the upper side of the convex baffle 222 forms an upward opening 223 at a position higher than the slot 221 . The convex baffle 222 of the slot 221 can block dust and foreign matter, and reduce the interference of external factors on the cooling fan.

In an optional embodiment, the outer side of the front panel 21 is further provided with an air deflector set 24 for adjusting the air direction, which is used for adjusting the flow direction of the cold air when the air cooler blows out the air.

The air cooler also includes a deflector 25 connected to the end of the front panel 21 away from the second air outlet 23 to guide the airflow of the air circulation of the air cooler.

When the air circulation mechanism of the air cooler provided by a specific embodiment of the present invention is used, the motor 11 of the fan drives the impeller 12 to rotate at a high speed. The tuyere 22 enters the U-shaped air duct, cooperates with the guiding effect of the deflector 25, and finally blows out from the air outlet 23 at high speed. The second air inlet 22 is added through the front panel 21, thereby increasing the area of the air inlet, so that the air cooler can obtain a larger air intake, and the air from the second air inlet 22 enters the U-shaped air duct and enters from the first air inlet 27 air mixing, although the second air inlet 22 is not provided with a wet curtain, it will cause the temperature of the air after mixing to rise, but because the air inlet area of the second air inlet 22 is smaller than the air inlet area of the first air inlet 27, and in Under the action of the wet curtain and the refrigerant installed in the air cooler, the temperature range of the mixed air can be controlled within a controllable range, thereby increasing the output power of the air cooler.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes and modifications can be made to these embodiments without departing from the principle and spirit of the present invention , replacement and modification, the scope of the present utility model is defined by the appended claims and their equivalent scope.
