基于半导体制冷的小型保温箱设计

The Design of Small Incubator based on Semiconductor Refrigeration

针对保温箱小型化的发展趋势,设计了基本半导体制冷技术的高精度保温箱实现方案,给出了保温箱的设计原理图和内部主要功能模块的详细实现方案.采用基于PID的控制策略,提高了保温箱温度控制的精度,使得所设计的高精度保温箱能够实现连续的、自动的温度调节能力.

For the trend of miniaturization of the incubator, this paper designed an implementation of high-precision incubator based on semiconductor refrigeration technology and presented the design principle of the incubator and main inner function module detailed implementation. To improve the incubator temperature control accuracy, it adopted PID control strategy and made the designed incubator can achieve the continuous, automatic temperature adjustment capability.
