  • Publication number: 20080232118
    Abstract: A street light includes a post with a light unit connected thereto. The light unit defines an enclosed space therein, and a separation board located in the enclosed space to divide the enclosed space into a first space and a second space. The separation board includes a hole. A circuit board includes multiple light emitting members and is located in the first space and on the separation board. The light emitting members are received in the hole of the separation board. A heat dissipating device is located in the first space and secured on the circuit board. The heat dissipating device extends to outside of the light unit. The heat generated from the light emitting members is transferred to the heat dissipating device which transfers the heat to outside of the street light.

  • Publication number: 20040066628
    Abstract: A rapidly self-heat-conductive heat-dissipating module is disclosed including: a plurality of heatsinks which are overlapped, but mechanically separable and discontinuous in contacting interface, at least one heat convection super conductive tubes containing high temperature super conductor composites, at least one heat dissipating fans assembled to an identical lateral side of the heatsinks. In addition to serving to buckle heatsinks together, heat convection super conductive tubes containing high temperature super conductor composites transfer heat to heatsink far away from heat generating source rapidly, whereby efficiency of heat dissipating increases. Mechanical separability between buckled heatsinks and discontinuity in contacting interface between heatsinks avoid heat dissipation of heatsink contacting heat source being impaired by the downward heat flow from heatsink far away from heat source.

  • Publication number: 20030182799
    Abstract: A method for forming a heat conductive device of superconductive metal block comprises the steps of: placing at least one heat conductive superconductive tubes or containers and melting metal material into a mold; shaping heat conductive superconductive tubes or containers and melting metal material into blocks by die-casting or casting mold so that the heat conductive superconductive tubes or containers are enclosed in the melting metals so as to be as an integral body. The metal block is a high heat conductivity metal, which may be integrally formed with fins. Furthermore, the heat conductive superconductive tube or container is bent to have a helical shape. The heat conductive superconductive tube or container is bent as a U shape or is bent to have a three dimensional shape. Moreover, there are a plurality of metal blocks which are stack packed one by one.

  • Publication number: 20030169287
    Abstract: A workstation-type mini computer comprises a motherboard, a small display, a wired receiving interface, a wireless receiving interface, and a wireless audio-video signal transmitter. The motherboard has at least one processor. The wired receiving interface receives signals from an external wired key-in device, which can be a keyboard, a mouse, or a touch-control panel, through an electric cable; the electric cable bridges the wired receiving interface and the external wired key-in device. The wireless receiving interface receives signals from an external wireless key-in device, which can be a keyboard, a mouse, or a touch-control panel, by a wireless transmission means. The wireless audio-video signal transmitter transmits output audio-video signals generated in the motherboard to a wireless audio-video signal receiver; the wireless audio-video signal receiver receives and then relays the output audio-video signals to a large-scaled display monitor for display.

  • Publication number: 20030164780
    Abstract: A workstation-type notebook computer capable of switching key-in devices and output display monitors comprises a motherboard, a key-in device, and a wireless audio-video (AV) signal transmitter. The key-in device is either of a keyboard, a touch-control panel, a mouse, and a joystick. The key-in device can be either built-in and therefore inseparable from the computer or separable from the computer by being disconnected at an input interface module. The wireless AV signal transmitter, used together with a wireless AV signal receiver, transmits the contents of an output AV signal from the motherboard to an external large-scaled display monitor that the wireless AV signal receiver is connected to.

  • Publication number: 20030019610
    Abstract: A rapidly self-heat-conductive heat-dissipating module has two fin sets which are overlapped. At least one heat convection super conductive tube is engaged with the two heatsink sets. One heatsink set is used to absorb heat from a heat source and the other one serves to dissipate heat. A heat dissipating fan blows air to the two heatsink sets for increasing heat dissipating efficiency. A plurality of rapidly self-heat-conductive heat-dissipating modules having heatsink sets and heat convection super conductive tubes can be assembled together and then heat dissipating fan is used to blow cold air. Therefore, the rapidly self-heat-conductive heat-dissipating module can dissipate rapidly and efficiently.

  • Patent number: 6467572
    Abstract: A muffler has an outer tube and an inner tube sealingly received in the outer tube. The inner tube has multiple shrink throats securely arranged therein and multiple through holes peripherally defined therein. Multiple baffles are formed between the outer tube and the inner tube and each of which has multiple openings. Every time when the exhaust air passes through the shrink throat in the inner tube, the speed of the exhaust air increases. Eventually, the efficiency of discharging the exhaust function increases. Due to the shrink throats, the backpressure from the exhaust air increasing, therefore hinders the power loss due to the early opening of the exhaust valve in the power (expansion) stroke.
