  • Patent number: 10932395
    Abstract: A thermal management device for dissipating heat from an electrical component includes a volume of working fluid configured to change from a liquid state to a vapor state in response to being heated by the electrical component. The thermal management device also includes a working fluid chamber configured to move the working fluid. The working fluid chamber includes an impermeable outer portion and a porous inner portion integrally formed with and connected to the impermeable outer portion. The inner portion is configured to move the working fluid when in the liquid state toward the electrical component. The impermeable outer portion is made of a first material and the porous inner portion is made of a second material. The first material is different from the second material.
    Type: Grant

  • Patent number: 8062576
    Abstract: A method for producing a moldable object having a hollow plastic component and a single-piece plastic stanchion is provided. The method includes molding the single-piece plastic stanchion in a first mold. The molded stanchion includes a first substantially-closed end and a second substantially-open end, and a cap joined with the second end via a living-hinge, enabling the cap to assume and maintain a position, such that the second end becomes substantially covered. The method also includes flexing the living-hinge, wherein the cap assumes and maintains the position such that the second end is substantially covered. The method additionally includes arranging the single-piece stanchion relative to a second mold after the second end is substantially-covered via the cap. Furthermore, the method includes molding the hollow plastic component in the second mold, such that the single-piece stanchion is fixedly retained by the hollow plastic component.
