Configurable heat conducting path for portable electronic device

A portable electronic device, comprising:

• a first housing comprising a front wall, a rear wall opposite to the first wall, and at least one side wall;
• and
• a second housing comprising a front wall, a rear wall opposite to the front wall, and at least one side wall, wherein the first housing slidable and rotatably connects to the second housing;
• both the first housing and the second housing comprise a circuit board comprising at least one heat generating component on at least one side of the circuit board, a transparent screen located on the front wall, a display module comprising at least one heat generating component, wherein the display module generates image and displays through the transparent screen;
• both the first housing and the second housing comprise a first heat remover disposed over a surface of the at least one heat generating component on either one of the display module and the circuit board, wherein the first heat remover comprises graphene;
• and
• the front wall, the at least one side wall and the rear wall of the first housing comprise a first housing heat remover comprising graphene for conducting the heat;
• and
• the front wall, the at least one side wall and the rear wall of the second housing comprise a second housing heat remover comprising graphene for conducting the heat;
• the first housing and the second housing are arranged as at least two configuration:
• in a first configuration, the rear wall of the first housing cover the front wall of the second housing, wherein the transparent screen of the second housing is covered;
• and in a second configuration, the transparent screen of the first housing and the transparent screen of the second housing are exposed;
• and
• wherein, a first heat conduction path, in the first configuration, comprises the first heat remover in the first housing thermally connected to the first housing heat remover on both the front wall and the at least one side wall of the first housing, the second housing heat remover on both the at least one side wall and the rear wall of the second housing;
• and
• the first housing heat remover on the rear wall of the first housing and the second housing heat remover on the front wall of the second housing are thermally disconnected;
• and
• wherein, a second heat conduction path, in the second configuration, comprises the first heat remover in the first housing thermally connected to the first housing heat remover surrounding on the front wall, the at least one side wall, and the rear wall of the first housing and the second housing heat remover surrounding on the front wall, the at least one side wall and the rear wall of the second housing.
