Abstract
Disclosed are a heat conductive sheet including a resin and a particulate carbon material, and having a thermal resistance value under a pressure of 0.05 MPa of 0.20° C./W or less, a heat dissipation device including the heat conductive sheet interposed between a heat source and a heat radiator, and a method of producing a heat conductive sheet.
Claims8
A heat conductive sheet comprising a resin and a particulate carbon material, and having a thermal resistance value under a pressure of 0.05 MPa of 0.20° C./W or less.
A method of producing a heat conductive sheet comprising:
- shaping a composition containing a resin and a particulate carbon material into a sheet by pressure application to provide a pre-heat conductive sheet;
- obtaining a laminate either by stacking a plurality of the pre-heat conductive sheets in a thickness direction or by folding or rolling the pre-heat conductive sheet;
- and
- slicing the laminate at an angle of 45° or less relative to the stacking direction to obtain a heat conductive sheet.
