Peltier cooling is the process of cooling an area or a device using the Peltier effect. This effect involves the flow of electric current across a junction between two dissimilar conductors, causing heat to be absorbed or released at the junction. Other synonyms for Peltier cooling include thermoelectric cooling, solid-state cooling, and semiconductor cooling. Thermoelectric cooling implies the use of the thermoelectric effect, which is another term for the Peltier effect. Solid-state cooling and semiconductor cooling refer to the use of solid-state materials such as semiconductors as the conductors in the Peltier effect. Regardless of the synonym used, this technology has many applications in various industries, including healthcare, electronics, and aerospace.
