基于半导体制冷技术的高低温试验箱设计
Design of High-Low Temperature Test Chamber Based on Semiconductor Refrigeration Technology
摘要
Abstract
Based on semiconductor refrigeration technology,a high-low temperature test chamber was designed,which took MC9S12XS128 as the core control chip,semiconductor refrigeration plate as the cooling device,and the silica sheet as the heating device.The accurate temperature measurement was conducted on multi-points of the test chamber through the optimized layout of DS18B20,and the measured temperature information was transmitted to the main control chip for real-time data processing.The temperature range can be set on the upper computer interface,which also shows the current temperature in the box.The experimental results show that the designed high-low temperature test chamber has the advantages of small size,simple structure,high control precision,and good stability.It can meet the rigid requirements of high precision instrumentation sensitivity test for the environment,and can be applied into practical projects.关键词
