This invention releases to a kind of notebook computer, and the aim of it is to resolve the problem that the existing notebook computer has a complicate structure because they cool by the cover. The notebook computer of this invention includes a cover conducting heat, a substrate with equipment giving heat off, and equipment for heat conduct. The equipment contains a first heat conduct and a second heat conduct and the part connecting them. The first heat conduct is fixed on one side of the cover, the second heat conduct is fixed on the base and one end of it contacts with the equipment giving heat off, the part connecting them is fixed on the other end of the second heat conduct. One end of the first heat conduct corradates with the connection part and rotate around it, to accomplish the relative rotation of the cover with heat conduct t to the base, between an open position and a close position.

The invention discloses a control method for a battery box of an electric vehicle, which comprises a battery pack, a water cooling assembly, a high thermal conductivity aluminum plate, a heat pipe radiator, a battery box (including a battery box main body and a cooling box), a control box, a wiring port, a heat dissipation Fans, thermocouples, etc. The battery box is composed of the cooling box and the main body of the battery box, which are connected by connecting angle plates with bolts. The cooling box is equipped with cooling fans, guide pulleys and positioning locks. The heat pipe radiator is fixed on the high thermal conductivity aluminum plate. The battery pack, water cooling components and thermocouples are arranged in the main body of the battery box. The control box and wiring port are located on one side of the main body of the battery box. The windward side of the main body of the battery box has a louver structure and is equipped with a wind filter plate, and a cooling fan is installed on the other side. Generally, the battery box of the present invention cools the battery pack through natural air cooling, water cooling and heat pipe heat dissipation. If the temperature controller monitors that the temperature of the battery pack exceeds the optimal threshold, it can control the heat dissipation fan at the air outlet of the main body of the battery box and the water-cooled box. The cooling fan on the cover plate starts to enhance the cooling effect.

The invention discloses a plastic injection mold, and relates to the technical field of injection molding. A rear formwork bottom plate is included. A rear formwork on the rear formwork bottom plate is detachably connected with a front formwork on a front formwork bottom plate. A cavity for mold injection molding is formed by a rear mold core formed by the upper portion of the rear formwork and afront mold core formed at the lower portion of the front formwork. Each exhaust assembly comprises a pipe cavity, wherein one end of the pipe cavity communicates with the cavity, the other end of thepipe cavity upwards extends out of the top face of the front formwork bottom plate, meanwhile, the pipe cavity is internally provided with a matched exhaust pipeline, and one end of the exhaust pipeline communicates with the cavity and is provided with a ventilation micro hole ring. According to the plastic injection mold, surplus air in the cavity is exhausted in time, accordingly, the phenomenonof air hole generation in the injection molding process is avoided, and the mold injection molding effect is improved; and an activated carbon adsorption plate can be utilized for adsorbing harmful molecules contained in hot melting plastic raw materials, and accordingly the body health of workers is facilitated while exhausting is guaranteed.

The invention discloses a protective member for an electric heating pipe of an air conditioner. The protective member comprises an electric heating pipe frame body for fixing an electric heating pipe, and a sleeve tray arranged on a cold region position pipe body at the tail end of the electric heating pipe in a sleeving manner, wherein the sleeve tray is used for carrying fragments falling from an electric heating pipe fusing position above the sleeve tray due to high temperature; the hollow inner ring size of the sleeve tray is matched with the pipe diameter size of the cold region position pipe body; the plane of the sleeve tray is vertical to the axial direction of the cold region position pipe body; the inner ring edge of the sleeve tray is provided with grid strips which extend upwards and clamp the tail end pipe body of the electric heating pipe; the grid strips extend to the junction of the tail end cold region and the heating region of the electric heating pipe all the way. The protective member has the advantages of simple structure, convenience in manufacturing, safety, reliability, high generality, low cost and long service life; the fragments falling from the high-temperature fusing position can be collected, so that ignition of the fallen fragments is avoided; the junction of the cold region and the heating region of the electric heating pipe can be still kept in a fixed state without falling after fusing.
