For example, as shown in fig. 1 and 2, when the heat exchanger 100 is an inline heat exchanger, the center planes of two adjacent heat exchanging fins 1 are parallel to each other, and at this time, the first bent portion 135 of one of any two adjacent heat exchanging fins 1 among the plurality of heat exchanging fins 1 and the inner wall of the positioning groove 131 of the other one of the two adjacent heat exchanging fins 1 are spaced apart from each other. As shown in fig. 3 and 4, when the heat exchanger 100 is an L-shaped heat exchanger, the central planes of two adjacent heat exchange fins 1 of the plurality of heat exchange fins 1 located on two straight sides of the L-shaped heat exchanger are parallel to each other, and the first bent portion 135 of one of the two adjacent heat exchange fins 1 on the two straight sides is spaced apart from the inner wall of the positioning groove 131 of the other of the two adjacent heat exchange fins 1.

The two adjacent rows of heat exchange fins 1 in the multi-row heat exchanger can be arranged along the width direction of the heat exchange fins 1, the included angle between the two heat exchange fins 1 in the two adjacent rows of heat exchange fins 1 can be 180 degrees, at this time, the first through hole 153 of one of the two heat exchange fins 1 of the two adjacent rows of heat exchange fins 1 is located at the lower end of the heat exchanger 100, and the first through hole 153 of the other of the two heat exchange fins 1 of the two adjacent rows of heat exchange fins 1 is located at the upper end of the heat exchanger 100. Alternatively, T1May be equal to 0.25T, T2May be equal to 0.75T-T3Each heat exchange fin 1 can be formed by cutting a long period section of the heat exchange fin 1 in a segmented manner. But is not limited thereto.
Four perforated holes 15 are shown in fig. 7 and 8 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to two, three or more than four perforated holes 15, which also falls within the protection scope of the present invention.
In some alternative embodiments, the minimum distance between the side wall of the first through hole 153 and the other end face of the heat exchange fin 1 is T4Wherein, T4Satisfies the following conditions: t is not less than 1.2mm4Less than or equal to 4.5 mm. When T is4When the diameter is less than 1.2mm, the minimum distance between the side wall of the first through hole 153 and the end surface of the lower end of the heat exchange fin 1 is too small, the lower end of the heat exchange fin 1 is easy to crack, and the stability of the heat exchange fin 1 in the heat exchanger 100 may be affected; when T is4When the diameter is larger than 4.5mm, the minimum distance between the side wall of the first through hole 153 and the lower end face of the heat exchange fin 1 is too large, the supporting force of the lower end of the heat exchange fin 1 is weak, and the heat exchange fin 1 is easy to topple and deform. Thus, when T is4Satisfies the following conditions: t is not less than 1.2mm4When being less than or equal to 4.5mm, the stability of the heat exchange fins 1 can be effectively ensured, meanwhile, the heat exchange fins 1 have enough supporting strength, and the heat exchange fins 1 are not easy to topple and deform.

For example, in the example of fig. 1 to 8, each heat exchange fin 1 is formed with four through holes 15, the four through holes 15 are arranged at intervals along the length direction of the heat exchange fin 1, and the heat exchange tubes 2 of the heat exchanger 100 can be arranged through the corresponding through holes 15, so as to connect a plurality of heat exchange fins 1 in series into a whole. The protrusion 151 is provided on a side wall of the perforation aperture 15, and the protrusion 151 extends away from the second surface 12, while the protrusion 151 and the perforation aperture 15 may together define a groove 152, and a side of the groove 152 adjacent to the first surface 11 is open. When the heat exchange fin 1 is installed, the protrusion 151 of the heat exchange fin 1 can be fitted into the groove 152 of the heat exchange fin 1 adjacent thereto. From this, two adjacent heat exchanger fin 1 can further play the effect of mutual support through arch 151 and recess 152 to can further improve the support intensity between two adjacent heat exchanger fin 1, and make a plurality of heat exchanger fin 1 compacter, and then can effectively avoid heat exchanger fin 1 to take place to empty.
Referring to fig. 7 and 8, since the positioning flange 13 and the protrusions 151 of the plurality of perforated holes 15 are located on the same side of the heat exchange fin 1, when installed, the first surfaces 11 of the plurality of heat exchange fins 1 may all be stacked toward the same direction, for example, the plurality of heat exchange fins 1 may be placed upright, in which case the length direction of each heat exchange fin 1 may be the same as the vertical direction, and the first surfaces 11 of the plurality of heat exchange fins 1 may be stacked in order toward the left side of fig. 1. From this, can effectively guarantee that even interval sets up between a plurality of heat transfer fin 1, make things convenient for heat transfer fin 1's installation and dismantlement simultaneously, improve assembly efficiency.
According to some embodiments of the present invention, as shown in fig. 7-10, a plurality of ventilation holes 16 may be disposed between two adjacent through holes 15, the ventilation holes 16 are disposed at intervals along the width direction of the heat exchange fin 1, each ventilation hole 16 extends along the length direction of the heat exchange fin 1, each ventilation hole 16 may be provided with two first extension plates 17 and at least one second extension plate 18, the two first extension plates 17 are disposed at two sides of the width direction of the ventilation hole 16, and one of the two first extension plates 17 extends obliquely toward a direction away from the first surface 11, and the other of the two first extension plates 17 extends obliquely toward a direction away from the second surface 12. The second extension plate 18 is provided between the two first extension plates 17, and at least one end of the second extension plate 18 in the length direction is connected to the side wall of the vent hole 16, and the second extension plate 18 and the two first extension plates 17 are parallel to each other. Therefore, the contact area between the heat exchange fin 1 and the air can be effectively increased, so that the heat exchange efficiency of the heat exchanger 100 can be improved, and the energy efficiency of the air conditioner can be improved.
