MFG Part Number AA-024-24-22-00-00
PowerCool Series Thermoelectric Cooler Assembly
The AA-024-24-22 is an Air-to-Air Thermoelectric Cooler Assembly that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via convection. Heat is absorbed and dissipated through high density heat exchangers equipped with air ducted shrouds and brand name fans. The heat pumping action is created by thermoelectric modules, which are custom designed to achieve a high coefficient of performance (COP). It has a maximum Qc of 24 Watts when ΔT = 0 and a maximum ΔT of 35 °C at Qc = 0.

You can interact with the Performance Curves below to estimate the cooling performance by entering the thermal and electrical operating conditions for your application.
