1. A heat dissipation device, comprising:
a body including a first metal sheet and a second metal sheet coupled to the first metal sheet, wherein the first metal sheet at least partially defines:
a first channel including a first plurality of curves;
a second channel including a second plurality of curves; and
an interconnecting channel fluidly coupled to the first channel and the second channel, wherein
a first end of the first channel is fluidly coupled to a first end of the interconnecting channel and a second end of the first channel is fluidly coupled to a second end of the interconnecting channel, wherein the first and second ends of the first channel are opposite each other and the first and second ends of the interconnecting channel are opposite each other,
a first end of the second channel is fluidly coupled to the first end of the interconnecting channel and a second end of the second channel is fluidly coupled to the second end of the interconnecting channel, wherein the first and second ends of the second channel are opposite each other,
the second channel extends transversely from a connection between the second channel and the interconnecting channel,
the first channel and the interconnecting channel at least partially surround the second channel,
an entirety of the first channel and an entirety of the interconnecting channel have the same unit volume as each other, and
the unit volumes of the first channel and the interconnecting channel are different from a unit volume of the second channel.
