1. A heat dissipating device, comprising:
a first plate;
a second plate opposite the first plate, wherein
the first plate and the second plate are connected to each other at longitudinally opposite ends thereof,
longitudinally extending ends of the first plate and the second plate are connected to each other by sidewalls,
the first plate, the second plate and the sidewalls enclosing an internal space of the heat dissipating device,
the first plate forms a top horizontal surface of the internal space, the second plate forms a bottom horizontal surface of the internal space, and each sidewall forms side surfaces of the internal space;
a first wick structure disposed in the internal space, wherein
the first wick structure extends longitudinally between the longitudinally opposite ends of the first plate and the second plate,
the first wick structure at least partially defines a first vapor flow channel of the heat dissipating device,
the heat dissipating device includes an evaporator section and an condenser section located at the longitudinally opposite ends of the heat dissipating device, the first wick structure is located in the evaporator section and the condenser section and directly contacts the top horizontal surface and the bottom horizontal surface in both the evaporator section and the condenser section,
the second plate extends horizontally and longitudinally to form an extended end at each longitudinally opposite end, the first plate extends longitudinally to form a transitional portion at each longitudinally opposite end that is sloped towards the second plate and connects the respective extended end of the second plate; and
the first wick structure extends an entire length of the heat dissipating device and is absent in the transitional portions.
