Description

technical field [0001] The invention relates to the technical field of high thermal conductivity gasket production, in particular to a single-cavity multi-flow channel applied to graphene fiber orientation arrangement extrusion molding equipment. Background technique [0002] With the rapid development of big data, 5G, AI, Internet of Things, etc., the heat source power of electronic components is getting larger and larger. Thermal pads can no longer meet the requirements of thermal conductivity, so thermal pads with higher thermal conductivity are urgently needed to meet heat dissipation requirements, and graphene fibers are gradually being used in the production of thermal pads due to their excellent thermal conductivity. [0003] Research has found that when the thermally conductive graphene fibers and sheets in the thermally conductive gasket are oriented in the same direction, they can achieve good thermal conductivity in the axial direction or in the plane direction of...

Problems solved by technology

[0003] Research has found that when the thermally conductive graphene fibers and sheets in the thermally conductive gasket are oriented in the same direction, they can achieve good thermal conductivity in the axial direction or in the plane direction of the sheet. In the molding stage, a single cavity is used to extrude the material, resulting in an unsatisfactory orientation arrangement of the thermally conductive graphene fiber and the sheet, which results in an unsatisfactory thermal conductivity of the thermal pad
