在两种不同导体(或半导体)组成的回路中通过电流时,一个接头会吸热,另一个接头会放热,接头的吸热或放热取决于电流的方向,这个现象称为珀尔帖效应。半导体温差电致冷组件就是利用这种效应致冷的一种器件。
When a current flows in a loop of two different conductors (or semiconductors), one connector absorbs heat and the other connector exotherms. The endothermic or exothermic behavior of the connector depends on the direction of the current, a phenomenon known as Peltier effect. Semiconductor thermoelectric cooling module is the use of such a cooling effect of a device.
