It should be noted that in the embodiments of the present invention, the term "substantially parallel" can be interpreted as parallel, nearly parallel, or at a certain preset angle; "substantially vertical" can be interpreted as vertical, nearly vertical, or at a certain preset angle.

[0059] For example, the second positioning portion 132 has a matching step 1321, which can press against the first matching portion 1224 and match with the second end plate 112, thereby limiting the up and down movement of the lower portion of the auxiliary heating element 120. The matching step 1321 can also press against the second matching portion 1225 and match with the matching structure of the tongue 1222 and the slot 1121, thereby limiting the movement of the lower portion of the auxiliary heating element 120 in the front-to-back direction. Therefore, the stability of the installation of the auxiliary heating element 120 and the bracket 110 can be further improved, and the performance of the heat exchange assembly 100 in resisting falling and deformation can be improved.

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 limit the movement of the upper portion of the auxiliary heating element 120 in the up-down direction, and cooperates with the matching structure of the base 1221 and the second end plate 112, thereby limiting the movement of the auxiliary heating element 120 relative to the bracket 110, and improving the stability of the installation of the auxiliary heating element 120.

[0062] Reference Figure 3 , Figure 8 and Fig.10 As shown, it can be understood that the inner wall of the groove 1111 extends upward to form a reinforcing rib 1112, thereby improving the structural strength of the first end plate 111 at the groove 1111, and the reinforcing rib 1112 abuts against the protrusion 1212, thereby improving the stability of the installation of the protrusion 1212; and during assembly, the workers can cut the reinforcing rib 1112 according to the size error to adapt to the assembly of the auxiliary heating element 120 within a certain processing error range, thereby improving the assembly efficiency of the auxiliary heating element 120 and enhancing the adaptability of the assembly of the auxiliary heating element 120.
