AC-60-30

60WAir-to-AirThermoelectricCoolingSystem

QuickDescriptionThe AC-60-30 is an air-to-air thermoelectric cooler with integrated fans and thermistor embedded in the ‘cold side’. The unit is formed around a 200mm x 100mm x 31mm dense fin aluminium heatsink extrusion. The cold side has a 12V 92mm x 38mm fan blowing air at the fins. On the opposite side the Peltier module is held on the extrusion by an aluminium heatsink with embedded heatpipes and a PWM-controlled 60mm x 25mm cooling fan. The rear face of the extrusion is covered with a 3mm thick layer of closed-cell neoprene. The unit has a cooling capacity of 60W and a ΔT(max) of 30°C.

The 60mm fan speed and input power is: • at duty cycle 0~20%: 1600 ± 200 RPM / 1.20W; • at duty cycle 50%: 4000 ± 10% RPM / 2.28W; • and at duty cycle 100%: 8000 ± 10% RPM / 7.2W

A ‘cold side’ thermistor allows direct measurement of the extrusion operating temperature.

Notes: 1. Both fans, the Peltier module and the thermistor are electrically isolated from the extrusion. 2. The cooler cannot be used as a heater by polarity reversal of the Peltier module current. 3. The “hot” side of the cooler should not be operated at a temperature below 2°C.

• The cold side fan can be used over the voltage range 6V to 12V. This gives a speed range of approximately 4:1. ΔT(max) is measured with a fan operating voltage of 6V. A slightly lower temperature is available from the unit if the fan is switched off entirely.

• NOTE: Providing there is no condensate build-up on the cold side extrusion the unit can be operated in any orientation. If there is a possibility of condensate forming then the unit should be mounted in such a way that condensate cannot fall on to the cold-side fan.

ThermistorThe thermistor is a 10k NTC type: Vishay NTCLE305E4. Polarity is not required.
