[0040] According to the heat exchanger 102 of the first aspect embodiment of the utility model, the heat exchanger 102 includes a front heat exchanger 10 and a rear heat exchanger 20. When the heat exchanger 102 is installed in the shell 101 of the air conditioner 100, the air conditioner 100 is a wall-mounted indoor air conditioner 100, and the front heat exchanger 10 is located in front of the rear heat exchanger 20, that is, the front heat exchanger 10 is located on the side of the rear heat exchanger 20 closer to the user.

[0041] The front heat exchanger 10 includes a plurality of front heat exchange fins 1, and the plurality of front heat exchange fins 1 are arranged along a first direction (for example, Figure 3 The rear heat exchanger 20 includes a plurality of rear heat exchange fins 2, and the plurality of rear heat exchange fins 2 are spaced apart along the first direction, wherein the plurality of front heat exchange fins 1 and the plurality of rear heat exchange fins 2 correspond one to one, and each front heat exchange fin 1 and the corresponding rear heat exchange fin 2 are an integrally formed heat exchange fin 30.

[0042] Each front heat exchange fin 1 in the front heat exchanger 10 precisely corresponds to a rear heat exchange fin 2 in the rear heat exchanger 20. The heat exchange fins 30 are integrally formed, and there will be no breakage between the front heat exchange fins 1 and the rear heat exchange fins 2. The heat exchange fins 30 have good sealing properties, which can prevent abnormal noises from occurring during the operation of the air conditioner 100, making the air conditioner 100 quieter during operation.

[0043] The heat exchange fins 30 in the heat exchanger 102 are integrally formed, which can reduce the number of fasteners connecting the front heat exchange fins 1 and the rear heat exchange fins 2 , simplify the process of assembling the heat exchanger 102 , and improve the assembly efficiency of the heat exchanger 102 .

[0044] According to the heat exchanger 102 of the embodiment of the utility model, the front heat exchanger 10 includes a plurality of front heat exchange fins 1, and the rear heat exchanger 20 includes a plurality of rear heat exchange fins 2. The plurality of front heat exchange fins 1 correspond to the plurality of rear heat exchange fins 2 one by one. Each front heat exchange fin 1 and the corresponding rear heat exchange fin 2 are an integrally formed heat exchange fin 30. The heat exchange fin 30 has good sealing performance, which can prevent abnormal noise when the air conditioner 100 is working, making the air conditioner 100 quieter when working; and the heat exchange fins 30 in the evaporator are integrally formed, which can simplify the assembly process of the heat exchanger 102 and improve the assembly efficiency of the heat exchanger 102.

[0045] According to some embodiments of the present invention, referring to Figure 4-Figure 8 The heat exchange fin 30 also includes a first bending portion 3, which is connected between the front heat exchange fin 1 and the rear heat exchange fin 2. The heat exchange fin 30 is suitable for bending at the first bending portion 3 to switch the heat exchange fin 30 from the first state to the second state. In the second state, the front heat exchanger 10 and the rear heat exchanger 20 construct a accommodating cavity 34 for accommodating the wind wheel.

[0046] In the first state, the front heat exchange fin 1 and the rear heat exchange fin 2 are in an unfolded state, and the heat exchange fin 30 is still in the stage of initial processing.

When the heat exchange fin 30 is in the second state and the air conditioner 100 is working, the wind wheel located in the accommodating cavity 34 can blow the cold or heat of the heat exchange fin 30 into the room to adjust the indoor temperature.

[0047] The second state of the heat exchange fin 30 is formed by bending the heat exchange fin 30 in the first state once, which reduces the number of bending times of the heat exchanger 102 and improves the manufacturing efficiency of the heat exchanger 102; and the bent heat exchange fin 30 has good sealing performance.

[0049] Compared with traditional straight fins, the arc-shaped front heat exchange fins 1 can guide the airflow more effectively, produce a stronger vortex effect, increase the contact between the airflow and the front heat exchange fins 1, increase the heat exchange area, and thus improve the heat exchange efficiency; and the arc-shaped front heat exchange fins 1 can also reduce the volume of the heat exchanger 102, so as to provide a larger surface area for heat exchange in a limited space, which is conducive to maintaining or improving the heat exchange performance in a compact design.

[0050] According to some embodiments of the present invention, referring to Figure 4-Figure 8 The first bent portion 3 has a missing corner 32 on one side away from the wind wheel.

[0051] In the first state, the notch 32 has a slit on the bottom corner facing the accommodating cavity 34. After the heat exchange fin 30 is switched from the first state to the second state, the front heat exchange fin 1 and the rear heat exchange fin 2 located on both sides of the first bending portion 3 move in directions away from each other, so that the front heat exchange fin 1 and the rear heat exchange fin 2 move along the slit, forming a cut angle between the front heat exchange fin 1 and the rear heat exchange fin 2.

A second bending portion 53 is arranged between the first side plate 41 and the second side plate 42. When the heat exchange fin 30 is bent along the first bending portion 3, the front heat exchange fin 1 drives the first side plate 41 and the rear heat exchange fin 2 drives the second side plate 42 so that the first side plate 41 and the second side plate 42 are bent along the second bending portion 53.

The use of the fixing member to fix the first side plate 41 and the second side plate 42 can make the method of fixing the front heat exchanger 10 and the rear heat exchanger 20 simple and easy to operate.
