[0028] It should be noted that the heat exchange mechanism 100 is applied to an air conditioner mounted on a wall, and the heat exchange mechanism 100 is used to exchange heat with air to achieve the heating or cooling function of the air conditioner. However, this is not limited to this. In other embodiments, the heat exchange mechanism 100 can be applied to an air conditioner cabinet or a ceiling unit, and the application scenario of the heat exchange mechanism 100 is not specifically limited.

[0029] The heat exchange mechanism 100 includes an evaporator 110, an electric heating element 120, a baffle 130, an electric heating bracket 140 and a mounting side plate 150. The evaporator 110 is fixedly mounted on the mounting side plate 150, and the evaporator 110 is used to exchange heat with air to achieve the heating or cooling function of the air. The baffle 130 is fixedly connected to the evaporator 110, and the electric heating bracket 140 is fixedly connected to the baffle 130 to fix the relative positions of the electric heating bracket 140, the baffle 130 and the evaporator 110 to prevent the electric heating bracket 140 from being displaced relative to the evaporator 110. The electric heating element 120 is in the shape of a long strip, one end of the electric heating element 120 is mounted on the electric heating bracket 140, and the other end is mounted on the mounting side plate 150 to achieve the fixed installation of the electric heating element 120, and the electric heating element 120 is used to realize the electric auxiliary heating function to improve the heating efficiency of the air conditioner.

[0030] In this embodiment, the evaporator 110 is V-shaped, and the evaporator 110 includes a first wall 111 and a second wall 112 connected to each other. The length of the first wall 111 is less than the length of the second wall 112. The first wall 111 and the second wall 112 are combined to form a preset angle, and the first wall 111 and the second wall 112 are both used to exchange heat with air. Specifically, the first wall 111 and the second wall 112 are integrally formed to improve the connection strength. However, it is not limited to this. In other embodiments, the evaporator 110 is U-shaped. In this case, the evaporator 110 also includes an arc-shaped wall. The first wall 111 is connected to the second wall 112 through the arc-shaped wall. The first wall 111, the arc-shaped wall and the second wall 112 are all used to exchange heat with air. The shape of the evaporator 110 is not specifically limited.

[0031] It should be noted that the first wall 111 is provided with a first end face 113 and a second end face 114 opposite to each other, and the first end face 113 is fixedly mounted on the mounting side plate 150. One end of the second wall 112 is flush with the first end face 113, and the other end is protruding from the second end face 114, and the end of the second wall 112 that is flush with the first end face 113 is fixedly mounted on the mounting side plate 150. The baffle 130 is fixedly connected to the evaporator 110, and is arranged on the side of the second end face 114 away from the first end face 113, that is, the baffle 130 is arranged on the side of the second wall 112.

[0032] Furthermore, the length of the electric heating element 120 matches the length of the first wall 111, so as to reduce production materials and production costs while ensuring the heating effect. Since the length of the first wall 111 is less than the length of the second wall 112, one end of the electric heating element 120 is fixed on the mounting side plate 150 for mounting the evaporator 110, so in order to ensure the stability of the installation of the electric heating element 120, the present application sets a baffle 130 outside the second end surface 114, and the electric heating bracket 140 is fixedly connected to the baffle 130, and the other end of the electric heating element 120 is fixed by the electric heating bracket 140, which is convenient and fast, has a good fixing effect, and prevents the electric heating element 120 from falling.

The baffle 130 is also connected to the side of the second wall 112 by screws to fix the relative position of the baffle 130 and the evaporator 110 to prevent the baffle 130 from being displaced relative to the evaporator 110, but it is not limited to this. In other embodiments, the baffle 130 can be fixedly connected only to the first wall 111 of the evaporator 110, or it can be fixedly connected only to the second wall 112 of the evaporator 110. The baffle 130 can also be connected and fixed by welding, and the connection position and fixing method of the baffle 130 are not specifically limited.

Specifically, the first blocking arm 144 and the baffle 130 are arranged at intervals to facilitate the wire 121 to be clamped into the holding cavity 147, and the wire fixing portion 142 and the baffle 130 work together to clamp and fix the wire 121, and prevent the wire 121 from slipping out of the holding cavity 147, thereby playing the role of fixing the wire.

[0037] In this embodiment, the bracket body 141 is welded to the baffle 130 to improve the connection strength between the bracket body 141 and the baffle 130 and prevent the bracket body 141 from falling off the baffle 130. However, this is not limited to this. In other embodiments, the bracket body 141 can be connected to the baffle 130 by screws, or the bracket body 141 can be bonded to the baffle 130.

In this embodiment, the number of reinforcing ribs 148 is two, and the two reinforcing ribs 148 are arranged at intervals to further improve the strength of the electric heating bracket 140, but it is not limited thereto. In other embodiments, the number of reinforcing ribs 148 may be three or four, and the number of reinforcing ribs 148 is not specifically limited.

[0042] In this embodiment, the edge of the electric heating bracket 140 is surrounded by an overlapped edge 149, that is, the edge of the whole formed by the wire fixing portion 142, the bracket body 141 and the installation portion 143 is provided with an overlapped edge 149. The overlapped edge 149 can increase the thickness of the edge of the electric heating bracket 140, so that the edge of the electric heating bracket 140 is smooth and does not cut hands, thereby preventing the electric heating bracket 140 from cutting the wire and improving safety.
