an electrothermocooler

a solid state heat pump used in applications where temperature stabilization, temperature cycling, or cooling below ambient temperature is required

a thermocouple which acts as a heat pump, albeit very inefficient, when electrical current is passed through it

An electrical device that uses two materials with different electrical potentials to cause heat transfer across the device.  A Peltier cooler still requires a means for getting the heat that is conducts away from itself and into the surrounding air.

a device that, when current is applied, gets hot on one side and cold on the other

an electronic package that consists of two sides - the hot side and cold side
