PHASE-CHANGING HEAT DISSIPATER AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a phase-changing heat dissipater and a manufacturing method thereof. The heat dissipater includes a main body, a capillary structure and a working fluid. The capillary structure is composed of a plurality of metal powders being provided on an inner wall of the main body with a spraying means and processed with a sintering process for being formed thereon; and the working fluid is filled in the main body. Accordingly, the capillary structure is able to be tightly adhered in main body, thereby effectively preventing the capillary structure from being damaged and enhancing the heat conducting performance of the phase-changing heat dissipater.
