  • Publication number: 20210381777
    Abstract: A method of manufacturing a heat dissipation device is disclosed. The heat dissipation device manufactured with the method includes two titanium metal sheets and a metal mesh. According to the method, the two titanium metal sheets and the metal mesh are subjected to a surface treatment, so that surface of any one of the titanium metal sheets and the metal mesh is modified to form a hydrophilic layer. With these arrangements, the titanium metal material can be freely plastically deformed and possess a capillary force, and the titanium metal sheet can therefore be used in place of the conventional copper sheet to serve as a material for making heat dissipation devices. The heat dissipation devices so produced can have largely reduced weight and largely improved heat dissipation performance.

  • Patent number: 11033949
    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.

  • Publication number: 20200025461
    Abstract: A heat dissipation unit manufacturing method is disclosed. The heat dissipation unit has a main body formed of a first and a second metal plate member, which together define a sealed chamber between them. The chamber has a wick structure and a working fluid provided therein, and a lip portion formed along an outer peripheral edge thereof. The lip portion includes a sinter-welded section perpendicularly connects the first metal plate member to the second metal plate member. In the heat dissipation unit manufacturing method, the first and the second metal plate member are joined along their peripheral edges by lap joint laser welding, in which a laser beam directly perpendicularly passes through the first metal plate member into one third to two thirds of a thickness of the second metal plate member, so that the two metal plate members are more firmly joined to create upgraded vacuum-tightness between them.
