Classification: CPC F  H | IPC F

Claim 0:
1. A heat dissipation device, comprising:
a first casing;
a second casing coupled to the first casing, the second casing including:
a body having,
an inner surface and an outer surface opposite the inner surface,
a first portion and a second portion, wherein the second portion extends laterally from the first portion, the first portion and the second portion are formed by a same first outer edge, the first outer edge is a peripheral joint between the first casing and the second casing, and the first portion has a larger cross-sectional area than the second portion, and
a plurality of columns formed on the inner surface and extending from the inner surface; and

a first wick structure disposed on the inner surface of the second casing and in the first portion and the second portion, wherein
the first wick structure is located in gaps between the plurality of columns and contacts the inner surface of the second casing,
the first wick structure includes a first longitudinally extending portion and a second longitudinally extending portion, the first wick structure has a bend at location where the first longitudinally extending portion and the second longitudinally extending portion connect,
the bend is located in the first portion,
the first longitudinally extending portion is located proximate a second outer edge of the heat dissipation device, wherein the second outer edge is located in the second portion, the first longitudinally extending portion extends in the first portion and the second portion, the second outer edge is the peripheral joint between the first casing and the second casing,
the second longitudinally extending portion is connected to an end of the first longitudinally extending portion and extends therefrom in the first portion, and
the second longitudinally extending portion extends away from a third outer edge of the heat dissipation device, wherein
the third outer edge is located in the first portion, is connected to the second outer edge, and is transverse to the second outer edge, the third outer edge being the peripheral joint between the first casing and the second casing,
a distance between the third outer edge and the second longitudinally extending portion increases as the second longitudinally extending portion extends away from the bend, and
an angle between the first longitudinally extending portion and the second longitudinally extending portion is greater than 90° and less than 180°.
