Air to Direct Peltier assembly module
ID-120-24-AL
The ID-120-24-AL is a standard Thermoelectric Assembly in Zicotec that heat dissipation is forced air on hot sides, and Liquid cooling connective on cold side. It provides active thermal solution to cooling objects. The hot side uses one high performance heat sink with brand name fan to realize lower thermal resistance. The cold side is liquid exchanger. The brand name thermoelectric modules are custom designed to achieve a high coefficient of performance to minimize power consumption. Custom configurations and moisture protection options are available.

THERMAL DESIGN
Thermal design simulation is beneficial to the design and development of Thermoelectric cooling unit. It helps engineer to work out a Thermoelectric Assembly in a short time.
The boundary conditions in simulation as below,
The ambient temperature in 35°C, the operation voltage 24VDC. A dummy heater exchanger generated 120w inside liquid exchanger. The simulation result requires thermoelectric cooling unit to maintain 35°C inside the exchanger, flow rate 4L/min.
Testing &Lab
Thermoelectric Assembly can be validated by real cooling performance testing. We used a standard enclosure for Air to Air series, a Standard dummy heater for Air to Direct series and Air to Liquid.
Installation Requirement
1. Install and use the unit in indoor only.
2.Enough insulation to cold side is important, it will reduce the heat leak, and condensation water in cold side.
3.Suitable cabinet cutout size 124x250mm. Enough insulation around cabinet is important. It will be helpful to improve cooling capacity. Recommend the thickness of insulation >10mm
3.Input power is less than 26.4VDC.
4.Clean the fan impeller and heat sink to keep the good heat transfer during maintenance. (Brush or air to remove the dust only, No water)
5.Use a fuse in line to protect input power lines.
Safety & Warning
- 1.Assemble the unit properly and mount the unit in vertical direction to make sure the condensation water that can flow out from heat sink fins.
- 2.Don’t input incorrect voltage to the unit.
- 3.Handle the unit carefully to avoid damage and hurt by the falling out.
