Title:
HEAT DISSIPATOR, AND STRUCTURE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2017162807
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat dissipator which maintains high heat dissipating property even when used in a long-term continuous and strong vibration.SOLUTION: A heat dissipator 3 is provided outside a housing 4 including a heat generating element 1 (light source) therein and is thermally connected to the heat generating element 1 via a connecting part 2, and dissipates the heat generated by the heat generating element 1 to the outside of the housing 4. The heat dissipator 3 is composed of a material containing graphite sheet. A density of the material containing graphite sheet is 1.5 g/cmor more. The material containing graphite sheet is composed of only a graphite sheet of one layer or more, or is composed of a graphite sheet of one layer or more and a resin or metal layer.SELECTED DRAWING: Figure 1
