DEFINITION

Classification: 62/3.2

Thermoelectric; e.g., Peltier effect:

(under subclass 3.1) Process or apparatus in which cooling is produced by either the conversion of heat into electricity or that of electricity into heat; e.g., the Peltier effect.

(1) Note. The following classes and subclasses are noted as involving a thermocouple or a thermoelectric device: Class 136, Batteries: Thermoelectric and Photoelectric, subclasses 203+; Class 236, Automatic Temperature and Humidity Regulation, subclasses 69+; Class 310, Electrical Generator or Motor Structure subclass 306; Class 318, Electricity: Motive Power System, subclass 317; Class 322, Electricity: Single Generator Systems, subclass 2; Class 324, Electricity: Measuring and Testing, subclasses 451 and 452+; Class 361, Electricity: Electrical Systems and Devices, subclasses 161+; and Class 374, Thermal Measuring and Testing, subclasses 179+.
