Abstract (en)

[origin: WO2019121197A1] The subject matter of the present invention is a device for dissipating heat from a heat source. Said device comprises a heat pipe, a heat inputting element and a heat outputting element, also called a heat sink, wherein the heat sink consists substantially of a thermally conductive thermoplastic composition with an in-plane thermal conductivity of from 1 to 50 W/(m*K), preferably of from 2 to 30 W/(m*K), and preferably of from 4 to 20 W/(m*K). Here, the quotient of the external diameter to the wall thickness of the heat pipe is preferably from 10:1 to 4:1. The subject matter of the present invention is also a light which comprises the device according to the invention.
