1834年,法国物理学家珀尔帖(Peltier)发现了一个有趣的现象:当直流电通过连接在一起的不同金属材料时,在接头处产生一端热,一端冷的现象,形成吸热端和放热端。改变导体的电流方向,可获得相反的制冷制热效果。这种现象又被称为珀尔帖效应,此项技术首先在尖端军事科技领域得到广泛应用。如:潜艇、航天器、导弹、雷达等。随着中国经济的迅速发展和人们生活水平的提高,目前,这一效应正在给冰箱行业带来一场革命。
In 1834, the French physicist Peltier discovered an interesting phenomenon: when a direct current is passed through different metal materials that are connected together, one end of the junction produces a cold, one end cold, forming an endothermic end Hot end. Change the current direction of the conductor, you can get the opposite effect of cooling and heating. This phenomenon is also known as the Peltier effect, which is first of all widely used in cutting-edge military science and technology. Such as: submarines, spacecraft, missiles, radar and so on. With the rapid economic development in China and the improvement of people’s living standards, this effect is now bringing a revolution to the refrigerator industry.
