Abstract
A capillary structure and a heat dissipation device thereof are disclosed. The capillary structure is applied to a two-phase fluid heat dissipation device. The capillary structure has a main body having an internal closed space. The main body has a top layer formed with multiple passages in communication with the closed space of the main body. Multiple column bodies are disposed in the closed space. The column bodies and the passages are staggered from each other. The heat dissipation device has an internal airtight chamber. A working fluid is filled in the airtight chamber. The capillary structure is disposed in the airtight chamber. The capillary structure provides respective bypass paths for the vapor working fluid and the liquid working fluid. Accordingly, the liquid working fluid and the vapor working fluid in the capillary structure will not interfere with each other or be interrupted by each other.
