基于半导体制冷片的便携式药品储藏盒

On the basis of comparison and study of the domestic and abroad portable medical storage box and thermoelectric cooler (TEC), we put forward the based on TEC of portable medical storage box design scheme. The design uses microprocessor as the control core of the whole system and semiconductor refrigeration slice as the perform component for medical storage box. By the effects of PID control algorithm, the design realizes the rapid, stable and accurate control of the temperature in the box. Test results show that, the design can meet the requirements of common medicines refrigerated storage, and is small portable, suitable for the transporting drugs which have temperature preservation.
