1. A heat dissipation device, comprising:
a first casing including:
a first inner surface having a first wick structure, the first wick structure including:
a first portion;
a second portion; and
a third portion,
wherein the first portion is disposed between the second portion and third portion;
a first outer surface opposite the first inner surface; and
a first mounting plate for receiving a first heat source disposed on the first outer surface and located overlapping the first portion of the first wick structure;
a second casing coupled to the first casing, the second casing including:
a second inner surface having a second wick structure, the second wick structure including:
a first portion opposite the first portion of the first wick structure;
a second portion opposite the second portion of the first wick structure; and
a third portion opposite the third portion of the first wick structure,
wherein the first portion of the second wick structure is disposed between the second portion and third portion of the second wick structure; and
a second outer surface opposite the second inner surface and including a second mounting plate different from the first mounting plate for receiving a second heat source, the second mounting plate located overlapping the first portion of the second wick structure;
a third wick structure having at least one bend and arranged between the first inner surface and the second inner surface and arranged in the first portions of the first wick structure and the second wick structure, and the third portions of the first wick structure and the second wick structure, the third wick structure at least partially overlaps the second mounting plate and the first mounting plate; and
a plurality of columns arranged between the first and second inner surfaces,
wherein thermal resistances of the first portion of the first wick structure, second portion of the first wick structure and third portion of the first wick structure are same as thermal resistances of the first portion of the second wick structure, second portion, and third portion, respectively,
the thermal resistances of the first portion of the first wick structure is less than the thermal resistances of the second portion and the third portion of the first wick structure, and
the thermal resistances of the first portion of the second wick structure is less than the thermal resistances second portion and third portion of the second wick structure.
