Abstract
Official abstract text for this publication.
A planar heat pipe includes a container having a hollow portion provided at a central portion thereof with two opposing plate-shaped bodies, and a working fluid enclosed in the hollow portion. The hollow portion is provided with a wick structure. At least one of the plate-shaped bodies is a composite member of two or more types of metal members that are laminated and integrated. A metal member of the composite member forming a layer that contacts the hollow portion has a thermal conductivity of greater than or equal to 200 W/m·K and a metal member of the composite member forming a layer that contacts an exterior has a thermal conductivity of less than or equal to 100 W/m·K, a peripheral portion of the hollow portion being sealed.

The invention claimed is: 1. A planar heat pipe comprising: a container having a hollow portion provided at a central portion thereof with two opposing plate-shaped bodies; and a working fluid enclosed in the hollow portion, the hollow portion being provided with a wick structure, at least one of the plate-shaped bodies being a composite member of two or more types of metal members that are laminated and integrated, a metal member of the composite member forming a layer that contacts the hollow portion having a thermal conductivity of greater than or equal to 200 W/m·K and a metal member of the composite member forming a layer that contacts an exterior having a thermal conductivity of less than or equal to 100 W/m·K, a peripheral portion of the hollow portion being sealed. 2. The planar heat pipe according to claim 1 , wherein the peripheral portion of the hollow portion is sealed by laser beam welding. 3. The planar heat pipe according to claim 1 , wherein the peripheral portion of the hollow portion is sealed by resistance welding. 4. The planar heat pipe according to claim 1 , wherein the composite member is a cladded material or a plated material. 5. The planar heat pipe according to claim 1 , wherein the metal member forming the layer that contacts the hollow portion is of copper, and the metal member forming the layer that contacts the exterior is of stainless steel. 6. The planar heat pipe according to claim 1 , wherein the metal member forming the layer that contacts the hollow portion has a layer thickness of less than or equal to half a thickness of the composite member. 7. A heat sink comprising a planar heat pipe, the planar heat pipe including: a container having a hollow portion provided at a central portion thereof with two opposing plate-shaped bodies; and a working fluid enclosed in the hollow portion, the hollow portion being provided with a wick structure, at least one of the plate-shaped bodies being a composite member of two or more types of metal members that are laminated and integrated, a metal member of the composite member forming a layer that contacts the hollow portion having a thermal conductivity of greater than or equal to 200 W/m·K and a metal member of the composite member forming a layer that contacts an exterior having a thermal conductivity of less than or equal to 100 W/m·K, a peripheral portion of the hollow portion being sealed.
