T/UNP 735-2025 Automotive TEC (Thermoelectric Generating Device) used in vehicle
Basic Information
Scope
Main technical content: This standard specifies the model naming, working environment, and overall requirements for vehicle-mounted semiconductor thermoelectric cooling (TEC) devices. The naming consists of five parts, including the symbol for semiconductor thermoelectric cooling devices and structural category. Devices are classified into low-temperature, medium-temperature, and high-temperature types based on the maximum operating temperature, with requirements for temperature, humidity, etc., in the working environment. The overall requirements cover basic aspects such as external dimensions and internal components. Performance requirements include multi-faceted capabilities like parameters and protection, and also specify test methods, inspection rules, as well as marking and packaging, applying to the production and inspection of such devices.
