It should be noted that the auxiliary heating element 120 generally adopts the form of electric auxiliary heating, such as a PTC heater. Of course, other forms of heaters can also be used.

[0027] In the heat exchange assembly 100 according to the embodiment of the present invention, both ends of the auxiliary heating element 120 are respectively inserted into the slot 1121 through the tongue 1222 in a plug-in fit manner, and the first mounting portion 121 is engaged with the groove 1111 in a snap-fit manner, making the overall connection of the heat exchange assembly 100 more stable and reliable. Moreover, the assembly of the auxiliary heating element 120 is simpler and more convenient, improving the assembly efficiency and reducing the labor cost.

[0028] Referring to Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , the heat exchange assembly 100 of this embodiment further includes an air duct component 130. The air duct component 130 is fixedly connected to the bracket 110, and the auxiliary heating element 120 is located between the heat exchanger 140 and the air duct component 130. The air duct component 130 abuts against the first mounting portion 121, restricting the movement of the upper part of the auxiliary heating element 120 in the front-rear direction. The air duct component 130 also abuts against the second mounting portion 122, restricting the movement of the lower part of the auxiliary heating element 120 in the front-rear direction, thereby restricting the movement of the entire auxiliary heating element 120, so that both the upper and lower parts of the auxiliary heating element 120 can be fixed to the bracket 110, and its connection is more stable and reliable, improving the possibility of deformation of the auxiliary heating element 120 during dropping and transportation after assembly, and significantly improving the reliability. It should be noted that in the embodiment of the present invention, "fixed connection" can be interpreted as a connection in a manner that they cannot move relative to each other.

[0029] Referring to Figure 6 , Figure 7 and Figure 8As shown, when the heat exchange component 100 of this embodiment is assembled, when the auxiliary heating element 120 and the bracket 110 are installed, only the tongue 1222 needs to be inserted and fixed into the slot 1121, and at the same time, the first installation part 121 is snapped into the groove 1111 for snap fixation. Then, the air duct component 130 is fixedly connected to the bracket 110 to complete the assembly. The use amount of screws is reduced, making the assembly of the heat exchange component 100 simpler and more convenient, improving the assembly efficiency, and reducing the labor cost.

The first mating part 1224 and the second mating part 1225 are perpendicular to each other. The second positioning part 132 abuts against the first mating part 1224 and the second mating part 1225 respectively. It should be noted that in the embodiments of the present invention, the term "substantially parallel" can be interpreted as parallel, nearly parallel, or having a certain preset angle; "substantially perpendicular" can be interpreted as perpendicular, nearly perpendicular, or having a certain preset angle.

[0032] For example, the second positioning part 132 has a mating step 1321. The mating step 1321 can press against the first mating part 1224 and cooperate with the second end plate 112, thereby being able to limit the up and down movement of the lower part of the auxiliary heating element 120. The mating step 1321 can also press against the second mating part 1225 and cooperate with the mating structure of the tongue 1222 and the slot 1121, thereby being able to limit the movement of the lower part of the auxiliary heating element 120 in the front and back directions. Therefore, the installation stability of the auxiliary heating element 120 and the bracket 110 can be further improved, and the anti-drop deformation performance of the heat exchange component 100 can be improved.

[0033] Referring to Figure 7As shown, it can be understood that the second mounting portion 122 further includes a base 1221, the base 1221 abuts against the second end plate 112, and the boss 1223 and the tongue 1222 are respectively connected to both ends of the base 1221 in the front-rear direction, so as to facilitate the arrangement of the positions of the tongue 1222 and the boss 1223, and the force on the second mounting portion 122 is more uniform, thereby improving the mounting stability of the second mounting portion 122, and further improving the structural stability of the auxiliary heating element 120.

[0034] Referring to Figure 12 and Figure 13 As shown, it can be understood that the first mounting portion 121 includes a clamping member 1211 and a protruding member 1212. The clamping member 1211 is clamped with the groove 1111, thereby restricting the movement of the upper part of the auxiliary heating element 120 in the left-right direction. The protruding member 1212 is connected to the clamping member 1211 and protrudes upward from the groove 1111. The protruding member 1212 abuts against the first end plate 111, which can restrict the movement of the upper part of the auxiliary heating element 120 in the up-down direction, and cooperates with the cooperation structure of the base 1221 and the second end plate 112, thereby restricting the movement of the auxiliary heating element 120 relative to the bracket 110 and improving the mounting stability of the auxiliary heating element 120.

[0035] Referring to Figure 3 , Figure 8 and Figure 10 As shown, it can be understood that a reinforcing rib 1112 is formed by the upward extension of the inner wall of the groove 1111, thereby improving the structural strength of the first end plate 111 at the groove 1111. The reinforcing rib 1112 abuts against the protruding member 1212, thereby improving the mounting stability of the protruding member 1212; and during assembly, workers can cut the reinforcing rib 1112 according to the dimensional error to adapt to the assembly of the auxiliary heating element 120 within a certain machining error range, improving the assembly efficiency of the auxiliary heating element 120 and enhancing the adaptability of the assembly of the auxiliary heating element 120.

[0036] Referring to Figure 2 , Figure 3 and Figure 4 As shown, it can be understood that the air duct component 130 includes a first positioning portion 131.

In addition, the first positioning portion 131 can also abut against the clamping member 1211, and can also achieve the limit of the first mounting portion 121, thereby restricting the movement of the first mounting portion 121 in the front-rear direction.

[0037] Referring to Figure 3 andFigure 8 As shown, it can be understood that the cross-sectional area of the protruding member 1212 is larger than that of the groove 1111, so that the protruding member 1212 can be supported on the first end plate 111, improving the strength of the protruding member 1212, and thus making the upper part of the auxiliary heating element 120 more stable in installation.

[0038] Referring to Figure 9 and Figure 10 As shown, it can be understood that the first end plate 111 is provided with a wire clamping groove 1113 for fixing the wire (not shown in the figure) of the auxiliary heating element 120, which is convenient for fixing the wire routing of the auxiliary heating element 120.
