| 20080268916 | COMMUNICATION DEVICE CHARGED WITH SOLAR ENERGY - A communication device charged by solar energy forms a foldable mobile phone by pivotably connecting a first pivot provided on one end of a host to a display. One end face of the display is provided with a second pivot. A solar plate is pivotably connected to the second pivot of the display to foldably cover on the display. With the above structure, if the electricity of the battery of the mobile phone is insufficient, the user can unfold the solar plate from the display to charge the electrically-connected battery of the mobile phone, thereby to overcome the inconvenience in supplementing the electricity of the battery. | 10-30-2008 |
| 20090165479 | SOLAR POWERED VENTILATION SYSTEM FOR AUTOMOBILE - A solar powered ventilation system using a blower of an air conditioner in an automobile is disclosed. The blower is driven by a solar generator mounted on a roof of the automobile. A relay is arranged between the solar generator and the blower for switching on/off. The relay is controlled by a controller. A thermosensor is connected to the controller for detecting inside temperature of the automobile. The controller controls the relay to switch on and controls the air conditioner into an external circulation mode when the automobile is choked and the inside temperature exceeds a threshold temperature. | 07-02-2009 |
| 20090237882 | HEAT SINK AND HEAT DISSIPATION DEVICE HAVING THE SAME - A heat sink includes a heat dissipation fins assembly, a heat spreader, and a heat pipe. The heat dissipation fins assembly includes a plurality of heat dissipation fins. A guide plate extruding from a bottom of each of the heat dissipation fins. The guide plate being connected to an adjacent heat dissipation fins. The heat dissipation fins are connected in series by the guide plate thereby defining a number of air channels. Each heat dissipation fin includes a through hole defined therein and aligned with each other. The heat spreader is disposed under the heat dissipation fins assembly and a through groove is formed in the heat spreader. A heat pipe passes through the through hole and the through groove. The heat sink has improved heat dissipation efficiency. | 09-24-2009 |
| 20090266522 | METHOD OF FLATTING EVAPORATING SECTION OF HEAT PIPE EMBEDDED IN HEAT DISSIPATION DEVICE AND HEAT DISSIPATION DEVICE WITH HEAT PIPE - A method of flatting evaporating section of a heat pipe embedded in a heat dissipation device includes the following steps: (a) providing at least a heat pipe and a base of the heat dissipation device to be thermally connected with the heat pipe, the base defining at least a groove for embedding the heat pipe therein; (b) positioning an evaporating section of the heat pipe on the groove of the base; (c) pressing the evaporating section of the heat pipe to embed the evaporating section into the groove of the base with a partial uneven surface of the evaporating section protruding out of the base; (d) flatting the protruded uneven surface of the evaporating section by polishing. | 10-29-2009 |
| 20090294104 | VAPOR CHAMBER - A vapor chamber includes a plate and a wick structure. The plate is provided therein with a working fluid, and the plate has a heated end and a condensed end. The wick structure comprises a first wick portion adhered to be opposite to the heated end, a second wick portion overlapping on the first wick portion, and a third wick portion adhered on the rest portion of a chamber. The aperture diameter of the first wick portion is larger than that of the second wick portion, or the aperture density of the first wick portion is smaller than that of the second wick portion. Therefore, the amount of working fluid attached to the second wick portion is smaller than of the first wick portion. As a result, after heated, the working fluid attached to the second wick portion will be vaporized more quickly, thereby increasing the efficiency of heat transfer and improving the heat-dissipating effect. | 12-03-2009 |
| 20100002424 | LED LAMP TUBE WITH HEAT DISTRIBUTED UNIFORMLY - A LED lamp tube which includes a hollow transparent tube, a LED lamp assembly disposed in the transparent tube, two conductive caps provided on both ends of the transparent tube respectively, and a circuit control unit. The circuit control unit includes a plurality of separated sub-portions. The respective sub-portions of the circuit control unit are distributed uniformly on the circuit board of the LED lamp assembly. Via the uniform arrangement of respective sub-portions of the circuit control unit, the heat within the LED lamp tube can be distributed uniformly, thereby lowering the temperature and facilitating the heat dissipation. | 01-07-2010 |
| 20100002439 | LED LAMP TUBE HEAT DISSIPATING STRUCTURE - A light emitting diode (LED) lamp tube heat dissipating structure is capable of dissipating heat in a tube quickly to improve the heat dissipating efficiency. A circuit board with a light radiating surface and a heat dissipating surface is contained in the tube, and the light radiating surface of the circuit board is electrically connected to LED lamps. Two conductive bushings are sheathed onto both ends of the tube and electrically connected with the circuit board, and at least one heat dissipating hole is disposed separately on both distal surfaces of the tube that covers the heat dissipating surface of the circuit board, such that external air is entered into the tube from the heat dissipating hole on a distal surface of the tube and dispersed from the heat dissipating hole on another distal surface of the tube for dissipating the heat in the tube. | 01-07-2010 |
