Three-dimension heat transmission device

Abstract

A three-dimensional heat transmission device includes a thermally conductive casing, at least one first heat pipe, at least one second heat pipe, at least one blocking wick structure and a first wick structure. The thermally conductive casing includes a first casing member and a second casing member. The second casing member is mounted on the first casing member, such that the second casing member and the first casing member together form a liquid-tight chamber. An end of the at least one first heat pipe is connected to the second casing of the thermally conductive casing, and is in fluid communication with the liquid-tight chamber. At least two ends of the at least one second heat pipe are connected to the second casing of the thermally conductive casing, and are in fluid communication with the liquid-tight chamber. The at least one blocking wick structure is located in an end of the at one second heat pipe. The first wick structure is disposed on the first casing member of the thermally conductive casing. The at least one blocking wick structure is connected to the first wick structure.
