Abstract: Disclosed herein is a plate-type vacuum heat transfer apparatus for a television. The apparatus includes a first plate and a second plate sealed to define an internal space in a vacuum state, a mesh member disposed between the first and second plates, and a heat transfer medium supplied to a portion of the internal space. Each of the first and second plates includes an edge protruding to a hexagonal honeycomb structure formed such that a vertex thereof is located in a direction of gravity. Hexagonal honeycomb structures of the first and second plates overlap at some edges to be offset from each other, thus providing the internal space for allowing communication and a flow passage of the heat transfer medium.
