▎ 摘 要
NOVELTY - The utility model claims a portable cooling device, comprising a canvas fixing bag, one side of the canvas fixing bag fixedly connected with with a plurality of semiconductor refrigerating sheets, one side of the canvas fixing bag fixedly connected with with a temperature sensing element, one side of the canvas fixing bag is provided with a mounting opening, the mounting opening is fixedly connected with with a fan, the top of the canvas fixing bag is provided with a mounting groove, the inner part of the mounting groove fixedly connected with graphene, one side of the graphene fixedly connected with sodium acetate solution bag, one side of the canvas fixing bag fixedly connected with with an electric quantity display. The utility model not only can reduce the temperature of the article by the semiconductor refrigerating sheet, and convenient for carrying improves the radiating efficiency of the device, at the same time, it can realize the adjustment of the refrigerating temperature by the temperature sensing element monitoring and the surface of the cooled object contact saves the electric energy, but also can absorb heat by the sodium acetate solution bag; It is convenient for warming the hand in winter.
