Abstract
A heat dissipation device includes a base plate and a plurality of fins arranged on the base plate. Each fin includes a fin body including a first metal sheet and a second metal sheet coupled to each other, wherein the fin body is curved and includes a first portion and a second portion transverse to the first portion, an evaporation channel defined in the first portion, one or more connecting channels disposed in the first portion and in fluid communication with the evaporation channel, a condensation channel defined in the second portion, and one or more auxiliary channels disposed in the second portion and in fluid communication with the one or more connecting channels and the condensation channel.
Claims11
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.
