In addition, the arrangement mode can increase the movable contact area between the support member 41 and the support protrusion 42, the movable contact area is the contact area between the arc-shaped groove 413 and the transition end surface 411 on the support member 41 and the contact groove 421 of the support protrusion 42, in addition, the whole contact surface is in a substantially smooth W shape, the contact groove 421 corresponding to the arc-shaped groove 413 and the transition end surface 411 can play a certain limiting role, so that the support member 41 only slides in the contact groove 421, and the relative movement of the support member 41 relative to the support protrusion 42 is limited, thereby being beneficial to maintaining the stability between the support member 41 and the heat exchanger 2.
