The invention discloses a miniature air conditioner based on a semiconductor chilling plate. The miniature air conditioner based on the semiconductor chilling plate comprises a heat preservation tank unit, a main circuit unit, a heat dissipation unit, a convection unit and an air exhaust unit, wherein the main circuit unit, the heat dissipation unit, the convection unit and the air exhaust unit are arranged in the heat preservation tank. According to the air conditioner, the characteristic of reversing of the cooling end and the heating end can be achieved through polarity reversing of the semiconductor chilling plate; the air conditioner integrates the refrigeration function and the heating function through design of the simple circuit; besides, by adopting the semiconductor chilling plate instead of a compressor, the necessary equipment size of the air conditioner is greatly reduced, and thus the air conditioner can be carried while an existing air conditioner with the compressor is difficult to carry; and in addition, the air conditioner has the advantage of having the diverse functions such as refrigeration, cooling and article storage, and has practical value.
Description
technical field [0001] The invention belongs to the field of power electronic products, and in particular relates to a miniature air conditioner based on a semiconductor refrigerating sheet, which can provide multiple functional modes. Background technique [0002] A semiconductor cooler, also called a thermoelectric cooler, is a heat pump. Its advantage is that there are no sliding parts, and it is used in some occasions where the space is limited, the reliability is high, and there is no refrigerant pollution. When direct current passes through a galvanic couple made of two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple, which can achieve the purpose of cooling. It is a refrigeration technology that produces negative thermal resistance, is characterized by no moving parts, and is relatively reliable. In addition, if the positive and negative poles of the semiconductor refrigeration sheet are reversed, th...
