Abstract: An electronic device and housing thereof are provided. The electronic device includes housing, a partition, multiple electronic elements, and a fan. The housing has a side edge, where the side edge is provided with a slit. The partition is disposed in the case, is separated by a distance with the slit, and divides the interior of the case into a first and a second space. The partition has a through hole, the second space is in communication with the first space through the through hole, and the first space is in communication with the outside of the case through the slit. The electronic elements and the fan are disposed in the second space, and an air outlet of the fan is adjacent to the through hole, so that air in the second space can be driven to flow from the first space to the outside through the slit.

Abstract: A liquid crystal display device includes a support frame having a bottom wall, and a main surrounding will extending upwardly from and formed integrally as one piece with the bottom wall. The bottom wall and the surrounding wall cooperatively define a receiving space. The bottom wall includes a first support disposed in the receiving space. The main surrounding wall includes a second support disposed in the receiving space and spacedly above the first support. A backlight module is supported on the first support. A liquid crystal display panel is supported on the second support so that the liquid crystal display panel is positioned above the backlight module.

Abstract: Simplifying a manufacturing method for producing wick structures of a vapor chamber includes providing a metal lid, providing a powder thermal spray gun to generate a high temperature blaze to melt a sprayed first powder into a melting surface status, and directly spraying the first powder with the melting surface status on an inner surface of the metal lid to form a first wick structure with a porous status over the inner surface of the metal lid. The manufacturing method further includes putting a cooling system outside the metal lid to keep the metal lid low temperature.

Abstract: A heat sink and a method for manufacturing a heat sink are described. A plate-like base is manufactured with a plurality of parallel grooves and a plurality of fins by an impact extrusion process. A high temperature heat treatment is performed to soften the plate-like base. The fins are positioned in corresponding grooves and an equal force is applied to both ends of the plate-like base so that the grooves are deformed and the fins are fixedly positioned. The method is simpler and significantly cheaper than that for conventional heat sinks.

Abstract: A heat-radiating structure of chip provides effective heat-radiating paths and also maintains good structural stability to protect chips. A bearing rack is connected beside a flip chip type chip on a circuit substrate. The bearing rack is connected with a heat-radiating sheet. A projective portion is disposed at the center of the heat-radiating sheet facing the chip. The surfaces of the projective portion and the chip are connected together through adhesive. Several grooves are disposed on the surface of the heat-radiating sheet facing the chip to reduce the weight of the heat-radiating sheet and maintain its structural rigidity. Each side of the bearing rack is not connected together to avoid regions with a too large local thermal stress. Moreover, heat-spreading paths for hot, air are also provided to prevent the heat-radiating sheet from extra stress due to hot expansion and cold shrinkage during baking in the packaging process.

Abstract: A heat dissipation device includes a thermally conductive base plate and a plurality of thermally conductive fin plates that are in thermal communication with the base plate. Each adjacent pair of the fin plates defines a channel therebetween, through which cool air is forced to flow. Each of the fin plates has a proximate side that is proximate to the base plate, a distal side that is opposite to the base plate, and a plurality of integral ribs that extend from the proximate side to the distal side, thereby permitting heat transfer from the proximate side to the distal side along the ribs. In addition, because each of the ribs enables formation of a small turbulent flow of the cool air, a temperature boundary layer of the air is broken in each of the channels, thereby permitting heat transfer from upstream ends of the channels to downstream ends of the channels. Because the sizes of the ribs are relatively small with respect to the widths of the channels, the cool air can flow smoothly through the channels.

Abstract: An improved structure of an electric shock device includes a handle, and a plurality of retractable rod portions. The handle has an interior accommodating therein a high voltage generator and a battery unit. The handle further has a control switch at a lower rim thereof. The retractable rod portions are arranged and assembled in order of size, and equipped with a retractable function by utilizing springs and retaining rods disposed therein. The rod portions are made of insulating materials and respectively provided with parallel positive and negative electrode plates on both sides thereof. The electrode plates nearest to the handle are connected to positive and negative terminals of the high voltage generator so as to supply the rod portions with the required high voltages. The permittivity of dielectrics on the rod portions that have different diameters is caused to be equivalent so that the conductance conditions of the rod portions are the same, and the rod portions can all generate electric arcs.

Abstract: An assembly screw driver having a handle with a through hole connecting the front end and rear end of the handle; the through hole has a support device fixed therein near the front end of the handle to support and secure the base of the body of the screw driver. The body and the handle of the screw driver are detachable and the base of the body may be inserted via the rear end of the handle along the through hole to engage with the support device so that the body may be concealed in the handle.
