Abstract
A heat radiation structure includes a metal mesh brought into contact with the surface of a die, and a heat receiving plate configured to sandwich the mesh between the surface of the die and the heat receiving plate. The mesh is impregnated with a liquid metal at least at a portion brought into contact with the surface of the die and has a shape in which intersection points of vertical and horizontal element wires are crushed in a thickness direction of the mesh. The mesh has a flat portion formed on the surface side of the element wire at each intersection point.
Claims7
A heat radiation structure for an electrical component which generates heat, comprising:
- a metal mesh in direct contact with a surface of the electrical component;
- and
- a heat radiator that sandwiches the metal mesh between the surface of the electrical component and the heat radiator,
- wherein the metal mesh is impregnated with a heat transfer fluid at least at a portion in contact with the surface of the electrical component and has a shape in which intersection points of vertical and horizontal element wires are flattened in a thickness direction of the metal mesh.
An electronic apparatus having an electrical component which generates heat, comprising:
- a metal mesh in direct contact with a surface of the electrical component;
- and
- a heat radiator that sandwiches the metal mesh between the surface of the electrical component and the heat radiator,
- wherein the metal mesh is impregnated with a heat transfer fluid at least at a portion in contact with the surface of the electrical component and has a shape in which intersection points of vertical and horizontal element wires are flattened in a thickness direction of the metal mesh.
A method for manufacturing an electronic apparatus having an electrical component which generates heat, comprising the steps of:
- applying a pressing force on a metal mesh;
- impregnating the metal mesh with a heat transfer fluid;
- and
- sandwiching the metal mesh between a surface of the electrical component and a heat radiator, whereby the metal mesh is in direct contact with the surface of the electrical component.
