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.
Claims16
A heat dissipation device, comprising:
- a plurality of parallel fins, each fin including a longitudinally extending body including a first metal sheet and a second metal sheet contacting the first metal sheet, the body including a first edge, a second edge longitudinally opposite the first edge, a third edge extending longitudinally between the first edge and the second edge, and a fourth edge opposite the third edge and extending longitudinally between the first edge and the second edge, wherein a working fluid is located between the first metal sheet and the second metal sheet, and the first metal sheet and the second metal sheet each at least partially define:
- a plurality of obstructers arranged in a first region of the fin that is located at or adjacent the first edge,
- a plurality of channels at least partially defined by the plurality of obstructers;
- an evaporator channel extending longitudinally along the fourth edge and fluidly coupled to the plurality of channels;
- a condenser channel extending longitudinally along the third edge and fluidly coupled to the plurality of channels;
- a connecting channel extending along the second edge and fluidly coupled to the evaporator channel and the condenser channel;
- and
- a dividing obstructer disposed between the evaporator channel and the condenser channel and between the plurality of obstructers.
