1. A heat dissipation structure, adapted to accommodate a fluid and thermally contact at least one heat source, comprising:
a heat conductive plate for thermally contacting the at least one heat source; and
a sealed channel arrangement located on the heat conductive plate, the channel arrangement comprising a wider channel portion and a narrower channel portion, the wider channel portion wider than the narrower channel portion, the wider channel portion connected to the narrower channel portion so that the channel arrangement forms a closed loop, and
the channel arrangement adapted to accommodate the fluid, such that the fluid absorbs heat generated by the at least one heat source through the heat conductive plate so as to at least partially change phase of the fluid;
wherein the heat conductive plate has a heat absorbing edge and a condensing edge opposite to each other, the wider channel portion comprises a plurality of first inclined channels and a plurality of first curved channels, two opposite ends of each of the plurality of first curved channels are respectively connected to two of the plurality of first inclined channels, the plurality of first curved channels and the plurality of first inclined channels are arranged along the heat absorbing edge, the narrower channel portion comprises a plurality of second inclined channels, a plurality of second curved channels and a returning channel, two opposite ends of each of the plurality of second curved channels are respectively connected to two of the plurality of second inclined channels, the second curved channels and the second inclined channels are arranged along the heat absorbing edge, the returning channel is closer to the condensing edge than the plurality of first inclined channels and the plurality of second inclined channels, and two opposite ends of the returning channel are respectively connected to one of the plurality of first inclined channels and one of the plurality of second inclined channels that are respectively located at two opposite sides of the heat conductive plate;
wherein the plurality of first inclined channels and the plurality of second inclined channels are inclined at an acute angle relative to the returning channel; and
wherein an angle between each of the plurality of second inclined channels and the returning channel is smaller than an angle between each of the plurality of first inclined channels and the returning channel.
