Abstract
Official abstract text for this publication.
A heat dissipation system for a heat source, wherein the heat dissipation system comprises a heat pipe, a heat coupling-in element, and a heat coupling-out element, wherein the heat coupling-out element comprises at least 50% by weight of a thermally conductive thermoplastic composition having an in-plane thermal conductivity of 1 to 50 W/(m*K). Also provided is a luminaire.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat dissipation system for a heat source, wherein the heat dissipation system comprises a heat pipe, a heat coupling-in element, and a heat coupling-out element, wherein the ratio of external diameter to wall thickness of the heat pipe is from 10:1 to 4:1, and wherein the heat coupling-out element comprises at least 50% by weight, of a thermally conductive thermoplastic composition having an in-plane thermal conductivity of 1 to 50 W/(m*K). 2. The heat dissipation system as claimed in claim 1 , wherein the heat pipe has been insert molded with the thermally conductive thermoplastic composition of the heat coupling-out element. 3. The heat dissipation system as claimed in claim 1 , wherein the thermally conductive thermoplastic composition is a composition containing a polycarbonate. 4. The heat dissipation system as claimed in claim 1 , wherein the heat source is a lighting means. 5. The heat dissipation system as claimed in claim 1 , wherein the heat dissipation system is a component of a luminaire. 6. The heat dissipation system as claimed claim 1 , wherein the heat dissipation system is a component of the housing of a vehicle lamp. 7. The heat dissipation system as claimed in claim 1 , wherein the heat coupling-out element is designed as a heatsink which is located inside or outside on the vehicle lamp lens. 8. A luminaire comprising the heat dissipation system as claimed in claim 1 . 9. The luminaire as claimed in claim 8 , wherein the luminaire is designed as a lamp.
