Abstract
A heat transfer device includes a first and second substrate, and a heat transfer layer. The first substrate includes a first plate and a first adhesive layer that is formed on the first plate. The second substrate includes a second plate and a second adhesive layer that is formed on the second plate. The heat transfer layer is sandwiched between the first adhesive and second adhesive layers, and includes a plurality of carbon flakes that is made from one of graphene or graphite. The carbon flakes lies on the first adhesive layer with partial overlap of the carbon flakes.
Claims19
A heat transfer device, comprising:
- a first substrate including a first plate and a first adhesive layer that is formed on said first plate;
- a second substrate including a second plate and a second adhesive layer that is formed on said second plate;
- and
- a heat transfer layer sandwiched between said first and second adhesive layers and including a plurality of carbon flakes that are made from a material selected from the group consisting of graphite, graphene, and the combination thereof,
- wherein each of said carbon flakes lies on said first adhesive layer with partial overlap of said carbon flakes.
A method of making a heat transfer device, comprising:
- heating a first substrate that has a first plate and a first adhesive layer so as to soften the first adhesive layer;
- disposing on the first adhesive layer a plurality of carbon flakes that are made from a material selected from the group consisting of graphite, graphene, and the combination thereof;
- blowing a hot air flow to the carbon flakes in a direction that is parallel to the first substrate in such a manner that each of the carbon flakes lies on the first adhesive layer with partial overlap of the carbon flakes so as to forma heat transfer layer;
- and
- disposing on the heat transfer layer a second substrate that includes a second plate and a second adhesive layer, in such a manner that the heat transfer layer is sandwiched between the first and second adhesive layers.
