1. A heat dissipation device, comprising:
a plurality of parallel fins, wherein each of the fins comprises:
a fin body including a first metal sheet and a second metal sheet coupled to each other, wherein the fin body includes a first portion, a second portion extending away from the first portion, and a curved portion located between and connecting the first and second portions such that an angle is formed between the first and second portions;
an evaporation channel extending across the first portion between the first and second metal sheets and substantially parallel to the curved portion;
a condensation channel extending across the second portion between the first and second metal sheets and substantially parallel to the curved portion;
a plurality of parallel connecting channels disposed between the first and second metal sheets and extending from the evaporation channel to the curved portion; and
a plurality of auxiliary channels disposed between the first and second metal sheets and extending from the condensation channel to the curved portion,
wherein each of the connecting channels is fluidically connected to a corresponding one of the auxiliary channels at the curved portion such that the evaporation channel is in fluid communication with the condensation channel.
