I.e. a plurality of supporting members are provided at both ends of the heat dissipating bridge 12 in the first direction, which is advantageous for improving the supporting stability.

In addition, the convex hulls 13 are further arranged on the fin body 1, and the convex hulls 13 can also form a reinforced heat exchange structure on the fin body 1, so that the heat exchange efficiency of the fin is further improved.

In one embodiment, as shown in fig. 1-4, the projection of the heat-dissipating bridge 12 with respect to the reference plane and the projection of the first support 2 with respect to the reference plane are at least partially coincident; the reference plane is perpendicular to the longitudinal direction of the fin body 1, and is parallel to the width direction of the fin body 1. The gas flows to the heat-dissipating bridge 12 after passing through the first support 2 and flows out from the side of the second support 3, and the first support 2 generates turbulence to the gas before flowing into the heat-dissipating bridge 12, thereby improving heat exchange efficiency.
