The invention discloses cooling and heating clothing, and belongs to the field of application of clothing. The cooling and heating clothing makes use of the property that
semiconductor elements, when current passes through, can take effects of cooling and heating, and the cooling and heating clothing is composed of the plurality of the
semiconductor elements 01, wherein the
semiconductor elements are connected and welded on a grid intersection point in the middle of a negative
electrode metal grid 02 and a positive
electrode metal grid 0.3 in a parallel mode, the semiconductor elements, filled with soft gel or cotton fibers 04, are formed as sheet-shaped structures, the semiconductor elements are seamed on the inner layer of the cooling and heating clothing, the semiconductor elements are powered by a
battery pack 09 and the semiconductor elements are controlled by an automatic temperature controller 08. During cooling, temperature of the semiconductor elements 01 and temperature of the negative
electrode metal grid 0.2 drop and meanwhile, temperature of the positive electrode
metal grid 03 rises, and by virtue of an external breathable fabric 05, outward heat dissipation is achieved. During heating, temperature of the semiconductor elements 01 and temperature of the negative electrode
metal grid 0.2 rise and meanwhile, temperature of the positive electrode
metal grid 03 drops, and by virtue of the external breathable fabric 05, outward heat absorption is achieved. Therefore, a purpose of keeping temperature in main part of a
human body is realized.
