Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-5, the surface hydrophobic structure of the air conditioner heat exchanger fin comprises a substrate 1 and a plurality of groups of protruding structures 2 arranged on the upper surface of the substrate 1 at intervals;
the arrangement of the convex structures 2 increases the heat exchange area of the surfaces of the fins of the heat exchanger.
The protruding structure 2 comprises a column 3 arranged on the substrate 1, a first bump 4 arranged on the upper part of the column 3 and a second bump 5 arranged on the side part of the column 3;
a spacing interval 7 is reserved between every two adjacent groups of the protruding structures 2, and third bumps 6 are arranged on the upper surface of the substrate 1 between the groups of the protruding structures 2;
the side parts of the cylinders 3 are provided with inclined planes 8, the horizontal distance between the opposite inclined planes 8 of two adjacent groups of cylinders 3 is gradually reduced from top to bottom, and the second lug 5 is positioned on the inclined planes 8.
In this embodiment, the side portions of the periphery of the column 3 are respectively provided with an inclined surface 8.
The surface hydrophobic structure of the air conditioner heat exchanger fin is beneficial to the combination and aggregation of micro water drops into liquid drops with larger volume.
As shown in fig. 2, when the heat exchanger operates, micro water drops are formed on the surfaces of the first projection 4, the second projection 5 and the third projection 6 or the cylinder 3;
as shown in fig. 3, the micro water droplets are generated continuously, and the micro water droplets move and merge into water droplets with slightly larger size under the action of self weight and the vibration action when the heat exchanger operates, and fill the interval 7;
as shown in fig. 4, after the interval 7 is filled, the water on the upper part of the column 3 and the water on the upper part of the interval 7 are combined and gathered; and finally, as shown in fig. 5, the water in the upper part of the column 3 and the interval zone 7 is gathered into liquid drops with larger volume at the upper part of the column 3 under the action of tension, and the liquid drops with larger volume flow away from the heat exchanger fins more easily.
The inclined planes 8 are beneficial to reducing the size of the interval 7 between the two opposite inclined planes 8, namely the water storage capacity of the interval 7 is reduced, and the final convergence difficulty of liquid drops with larger volume is reduced. Meanwhile, the inclined surface 8 has the function of guiding water drops and promotes the water drops to enter the interval 7.
Further, the top of the first bump 4 and/or the outer side of the second bump 5 are/is provided with a circular arc portion 9.
In this embodiment, the top of the first bump 4 and the outer side of the second bump 5 are both provided with an arc portion 9.
The water drops on the first lug 4 and the second lug 5 can be transferred along the arc part 9 and combined with other water drops under the action of self weight and the vibration action when the heat exchanger runs, so that the combination and convergence of the water drops are promoted by the arrangement of the arc part 9.
Further, the left side and/or the right side and/or the front side and/or the rear side of the column 3 are provided with second protrusions 5.
In this embodiment, the left and right sides and the front and rear sides of the column 3 are provided with second protrusions 5.
