    郑永明1,方方1,徐建一2,郑燕红3 (1.成都理工大学,四川 成都 610059; 2.中国测试技术研究院,四川 成都 610021;3.仙居县安州中学,浙江 仙居 317300)   摘要:作为一种技术先进、可靠性高、又无污染的制冷新器件,半导体致冷可以广泛应用于各种小功率温度控制系统。例如便携式汽车冷暖箱,冷热饮水机、微机芯片的致冷等等。本文详细叙述了拍尔帕效应、半导体致冷片(器件)的工作原理、工作过程、及其特点。并研究开发了一套基于单片机控制为核心,数字式温度传感器,半导体致冷片,以及固态继电器配合使用的微机芯片温度检测致冷控制系统。该系统具有很强的实用性和可移植性。   关键词:半导体致冷;珀尔帖效应;电致冷;数字式温度传感器;固态继电器   中图分类号:TB66 文献标识码:A 文章编号:1672-4984(2006)02-0049-03   Research of the principle of semi-conductor refrigerant and its’application   ZHENG Yong-ming1,FANG Fang1,XU Jian-yi2,ZHENG Yan-hong3 (1.Chengdu University of Technology,Chengdu 610059,China; 2.National Institute of Measurement and Testing Technology,Chengdu 610021,China; 3.Xianju Anzhou Middle School,Xianju 317300,China)   Abstract: As a new technological refrigerant instrument with high functional reliability and pollution-free, semi-conductor refrigerant instrument can be extensively used in small-power temperature-control system, such as automobile cold-hot bin ,cold-hot drinking trough and refrigeration of chips in microcomputer, etc. This text described peltier effect, the principle and work process of the semi-conductor refrigerant instrument and its characteristics in detail. The paper showed a set of temperature detecting and control system based on singlechip digital temperature sensor and solid relay. The system was used in microcomputer chips’refrigeration and proved to be great practicable and migration.   Key words: Semi-conductor refrigeration; Peltier effect;Thermoelectric refrigeration;Digital temperature sensor;Solid relay
