  • Patent number: 11964811
    Abstract: A liquid storage tank includes a housing, a piston located in the housing, a cover, an elastic element, and an outlet pipe. The cover is attached to the housing and has a support post extending toward the piston. The piston, the housing, and the cover define a tank chamber. The tank chamber is filled with cooling liquid. The elastic element is connected with the tank hosing and the piston. The elastic element is free from contact with the cooling liquid. The outlet pipe communicates with the tank chamber. An extension direction of an opening of the outlet pipe is not parallel to a direction of movement of the elastic element. When the cooling liquid is decreased, the piston compressed the tank chamber such that the elastic element is released. The tank chamber is continuously compressed by pairing the elastic element and the piston.

  • Patent number: 11549667
    Abstract: A lighting device includes a housing, a light emitting module, a press plate and a fixing member. The housing has a bottom plate, a base and multiple stopping portions. The base protrudes from the bottom plate, and has a top surface and an inclined surface. The stopping portions are arranged at the bottom plate and extend to a bottom portion of the inclined surface of the base. The light emitting module includes a light panel and multiple light emitting elements arranged thereon. The light panel leans on the inclined surface and stopped by the stopping portions. The press plate is located at the top surface, and presses against the light panel. The fixing member fixes the press plate at the top surface to cause the press plate to press the light panel downward, so as to fix the light panel on the inclined surface.

  • Publication number: 20140338194
    Abstract: A heat dissipation device and a manufacturing method thereof. The heat dissipation device includes a first chamber defining a first cavity, a second chamber defining a second cavity, and multiple connection members each defining a passageway. First and second ends of the connection members are respectively connected with the first and second chambers in communication with the first and second cavities through the passageways. A working fluid is contained in the first cavity. When the working fluid is heated, the working fluid is evaporated into vapor. The vapor passes through the passageways into the second cavity. After reaching the second cavity, the vapor is condensed into liquid state. Then, the liquid goes back into the first cavity through the passageways to complete a working cycle and achieve heat dissipation effect.

  • Publication number: 20120255708
    Abstract: A heat exchange apparatus includes an enclosure and a heat exchanger. The enclosure internally defines a first space and a second space isolated from each other, and is provided with a first and a second air inlet communicating with the first and the second space, respectively. The heat exchanger is arranged inside the enclosure and located between the first and the second space. By providing the heat exchanger between the first and the second space inside the enclosure, heat can be exchanged between the first and the second space to enable effectively upgraded heat exchange efficiency, and a device using the heat exchange apparatus is protected against invasion by foreign matters via the heat exchange apparatus.
