Analysis of Electronically Controlled Thermal Resistance Based on Peltier Element

主要介绍了基于半导体致冷器的温度控制系统来实现对具有一定热源的物体(如集成电路)进行温度控制,使 其温度趋近于室温、广义热阻趋于零的方法。并结合当前应用比较多的控制方式提出了一种新型简便的控制方式,即通过 热源的功率来控制半导体致冷器的珀耳帖电流,达到广义热阻趋于零的目的。该控制方式具有一定的实用价值。

A temperature controlled system was introduced,which employs a Peltier cell to control the temperature of a device.The device is needed to be cooled,and the temperatue of the device-Peltier cell interface can be kept close to the ambient temperature.Thus a virtually zero thermal resistance can be realized.A new control mode was presented.In this mode,the value of the device power was used to actively control the current of the Peliter cell,and the purpose of zero thermal resistance was reached.
