Abstract

The invention discloses a thermoelectric refrigerating sheet control circuit, control method and a refrigerating device. The thermoelectric refrigerating sheet control circuit comprises a control circuit, a driving circuit, a switching circuit and a plurality of thermoelectric refrigerating sheets; after a system is powered on, the control circuit is used for generating a control signal accordingto a preset time sequence in a preset time (in an original state); the switching circuit controls the power on hours of each thermoelectric refrigerating sheet in the same period according to the control signal; and the driving circuit drives the plurality of thermoelectric refrigerating sheets to circularly power on. According to the control circuit, control method and the refrigerating device, the single driving circuit is adopted to drive the plurality of thermoelectric refrigerating sheets to circularly power on, so that the complexity and the control difficulty of a circuit system are reduced, and the miniaturization of a thermoelectric refrigerating sheet control circuit is realized.

Description

technical field [0001] The invention relates to the technical field of semiconductor refrigeration, in particular to a thermoelectric refrigeration sheet control circuit, a control method, and a refrigeration device. Background technique [0002] A semiconductor cooler, also called a thermoelectric cooler, is a heat pump. Utilizing the Peltier effect of semiconductor materials, when direct current passes through a galvanic couple formed by 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. [0003] In some applications, multiple thermoelectric cooling chips are needed. The existing method is to use multiple driving circuits to drive the thermoelectric cooling chips one-to-one, which not only increases the complexity of the circuit system and the difficulty of control, but also cannot The miniaturization of the control circuit of the thermoelectric cooling sheet is ...
