Abstract: A manufacturing method of heat dissipation unit is disclosed. The heat dissipation unit is mainly composed of two titanium metal plate bodies. The titanium metal plate bodies are heat-treated, whereby the titanium metal plate bodies can be mechanical processed, shaped and surface-modified. Accordingly, the titanium metal can be freely shaped and provide capillary attraction. In this case, the titanium metal plate bodies can be used as the material of the heat dissipation unit instead of the conventional copper plate bodies to greatly reduce the weight and enhance the heat dissipation performance.

Abstract: A heat dissipation device includes two titanium metal sheets, which are subjected to a heat treatment before undergoing mechanical processing, plastic working and surface modification. With these arrangements, the titanium metal sheets can be freely plastically deformed and possess a capillary force, and can therefore be used in place of the conventional copper material to serve as a material for making heat dissipation devices, and the heat dissipation devices so produced can have largely reduced weight and largely improved heat dissipation performance.
