Sheet having high thermal conductivity and flexibility

A thermal conduction module, comprising:

• a heating body having an outer surface disposed in a first orientation;
• a radiating body having an outer surface disposed in the first orientation;
• and a sheet arranged between the outer surface of the heating body and the outer surface of the radiating body, wherein the sheet having a plurality of graphite layers and a plurality of elastic layers arranged alternately, wherein the graphite layers and elastic layers are oriented in a second orientation perpendicular to the first orientation and each graphite layer comprises first and second ends in the first orientation and a central layer portion in the second orientation and wherein individual layers of graphene within the central layer portion of the graphite layer are oriented in the second orientation, each of the ends of each graphite layer extending beyond one of a top and a bottom end of an adjacent elastic layer and being disposed in the first orientation so as to cover at least a part of a top or a bottom end of an adjacent elastic layer, and wherein one end surface of the graphite layer in the first orientation is in contact with the outer surface of the radiating body and another end surface in the first orientation is in contact with the outer surface of the heating body, wherein spaces occur between at least one of the outer surface of the heating body and the sheet and the outer surface of the radiating body and the sheet and further comprising a filling material in at least one of spaces between the outer surface of the heating body and the sheet, and between the outer surface of the radiating body and the sheet.
