Paper Abstract

A design of semiconductor ice box is introduced in the paper, which is cooled by solar power supply. The box is constituted by four major parts. There are a solar power panel, a solar charge controller, a hermetic box and a series of semiconductor frigorific pieces. The solar power panel collects solar energy through the Photovoltaic effect. The solar energy is stored in storage battery after being regulated by the DC/DC converting circuit of the solar charge controller. The charge controller circuit contains over-charging circuit, over-discharging circuit, short circuit, overload circuit and reversed polarity protection circuit. The storage battery supplies power to the ice box. The solar charge controller can automatically track the maximum power point in terms of the solar intensity. The cooling system is made up of semiconductor frigorific pieces, whose power is exclusively provided by solar energy. The whole device is small and portable, and can be applied in some areas of environmental protection and energy saving.
