TE Technology AC-3326 Peltier Thermoelectric Air Cooler

TE Technology AC-3326 Peltier Thermoelectric Air Cooler is a compact, solid-state cooling module that uses a thermoelectric (Peltier) junction to move heat from inside an enclosure to the surrounding air, enabling targeted cooling of electronics. This unit is part of TE Technology's AC-series of Peltier thermoelectric air coolers, designed to cool enclosure interiors such as control panels, telecom boxes, and instrument housings. It typically employs a heat sink with airflow managed by an integrated or external fan to dissipate heat to ambient air, a configuration documented in TE Technology datasheets for AC-series products. Because it relies on a thermoelectric module rather than refrigerants, the AC-series cooler provides a maintenance-light, solid-state cooling solution with no moving parts in the cooling path that affect the cooling itself. TE Technology's AC-046 and related models illustrate how these units are packaged for enclosure cooling with mounting options and airflow considerations that match compact electronics environments.
