Abstract: The present invention is related to a flexible, heat-conducting, insulating, and viscous phase change heat dissipation sheet, and a preparation method therefor and a battery thermal management system thereof. The phase change heat dissipation sheet comprises the following components in percentage by mass: 65-75% of paraffin, 10-20% of polystyrene-polyethylene-polybutylene-polystyrene, 10-20% of boron nitride, and 1-3% of polyvinyl alcohol. The present invention uses an elastic plastic to provide a flexible support substrate for a phase change material, and uses the elliptic/circular laminated sheet-shaped boron nitride as a heat-conducting filler, so that a finally prepared composite material has excellent heat-conducting property and electrical insulation property. Moreover, the prepared thin sheet has flexibility, and can be widely applied to the thermal management of lithium batteries having different shapes, such as cylindrical batteries, cuboid hard-shell batteries, and pouch batteries.

Abstract: A phase-change energy-storage structure for building insulation. The wall structure is provided with a wall base, an insulation layer, an oriented structural board, a shaped phase-change energy-storage insulation board, and an exterior decorative board in sequence from outdoor to indoor. The shaped phase-change energy-storage insulation board is composed of an inorganic composite phase-change material and a packaging sheet. The inorganic composite phase-change material has a phase-change temperature of 10 to 40° C., obtained by compounding an inorganic hydrated salt and a porous structural carrier. In the inorganic composite phase-change material, a mass percentage of the inorganic hydrated salt is 40 to 95%, and the inorganic composite phase-change material is coated with a fire resistant and corrosion resistant light-cured resin. The coldness in outdoor air in summer night can be stored in the phase-change energy-storage insulation board, which can be released into the indoor air during the day.

Abstract: The present invention relates to a hyperthermia mask used in the field of medical appliances. The hyperthermia mask of the present invention comprises a mask surface body and a tensioning belt, the mask surface body is made of phase change fibers or the mask surface body is filled with the phase change fibers; the phase change fibers are composed of hollow fibers and phase change materials filled into the hollow fibers; and the phase change materials have a phase change temperature of 40° C.-55° C. The hyperthermia mask of the present invention is prepared based on phase change heat storage, is convenient to use and has a good hyperthermia effect.

Abstract: A media file playing method and device. The method comprises: submitting information about a media file to a first window; judging whether the first window is a browser top window; if so, creating a sub-window in the browser top window, setting the sub-window as the first window, loading player logic in the browser top window, and playing the media file by using the player logic in the browser top window; otherwise, transmitting, by the first window, the information about the media file to the browser top window to which the first window belongs, and playing the media file by using the player logic in the browser top window. By means of the present invention, it can be achieved that a webpage player window can play a new media file without refreshing when playing requests of other webpage browser windows are received.

Abstract: A combined-type light load crossbeam (2) which is horizontally arranged is arranged in the middle portion of a crossbar (1) of a frame of the skeleton semitrailer, and two combination locksets which are used for fixing two adjacent corner columns of two containers are arranged at two ends of the light load crossbeam (2). The combination lockset comprises a pair of lifting locks (5), turnover locks (6) or fixing locks, or a combination of any two thereof. The two locksets of the combination lockset are separately arranged at the front and back of an end of the light load crossbeam (2), or short beams (3) of the locksets are separately arranged at an outer side of the end of the light load crossbeam (2). Thereby, the number of crossbeams is reduced, the weight of the skeleton semitrailer is lightened, and the structure of the frame is simplified.
