Heat Pipes, Vapor Chambers, and 3DVC
Effective thermal management is essential for modern electronics, ensuring performance and longevity. Three advanced technologies—heat pipes, vapor chambers (VC), and 3D vapor chambers (3DVC)—play pivotal roles in dissipating heat efficiently. This article explains how these systems work, their unique advantages, and where they excel in real-world applications.
1.Heat Pipes
Heat pipes are sealed, vacuum-filled tubes typically made of copper or aluminum. Inside, a small amount of working fluid (e.g., water, ethanol) undergoes phase change to transfer heat. When heated at one end, the fluid vaporizes, carrying thermal energy to a cooler section where it condenses. Capillary structures (e.g., sintered powder or grooves) then return the liquid to the hot end, enabling continuous heat redistribution.
2.Vapor Chamber（vc）
Heat pipes are sealed, vacuum-filled tubes typically made of copper or aluminum. Inside, a small amount of working fluid (e.g., water, ethanol) undergoes phase change to transfer heat. When heated at one end, the fluid vaporizes, carrying thermal energy to a cooler section where it condenses. Capillary structures (e.g., sintered powder or grooves) then return the liquid to the hot end, enabling continuous heat redistribution.
3.3D Vapor Chamber（3DVC）
Heat pipes are sealed, vacuum-filled tubes typically made of copper or aluminum. Inside, a small amount of working fluid (e.g., water, ethanol) undergoes phase change to transfer heat. When heated at one end, the fluid vaporizes, carrying thermal energy to a cooler section where it condenses.
