A semiconductor cooling device as a special source of cold, the technology has the following advantages and characteristics: does not require any refrigerant, can work, there is no source of pollution there is no rotating parts, will not produce rotation effect, there is no sliding parts is a The devices of the kinds of solid work without vibration, noise, long life, easy to install. Semiconductor cooling device has two functions, not only cooling but also heating and cooling efficiency is generally not high, but the induced thermal efficiency is high, always greater than 1. Therefore, a device can replace the discrete heating and cooling system.<\/p>\n
