TEC1-12715 Thermo Electric Peltier Cooler TEC1 12715

DC 12V 15A 231W Mini Air Conditioner Fan Refrigerator Freezer Cold Air Generator Temperature Reducer

Cooling of the hot surface is mandatory. If it is not cooled, the product will burn within seconds.

     The TEC1-12715 Peltier is a 40mm x 40mm ceramic thermoelectric plate that creates a temperature difference between its 2 surfaces when electricity is applied. It runs on 12V, withstands up to 15V and 15A, and its maximum power consumption is approximately 231W. Inside, 127 semiconductor couples are arranged between two ceramic plates; in the model name, 127 is the number of couples and 15 is the maximum current.

     While the temperature rises on one surface, it decreases on the other; under ideal conditions a difference of approximately 68°C can form between the two surfaces and approximately 130W of heat can be pumped from the cold surface. When the polarity is reversed, the cold and hot surfaces swap; the same plate can be used for both cooling and heating. It has no moving parts and runs silently without vibration.

     The hot surface must also be cooled with an external cooler. Otherwise very high heat builds up on the hot side in a short time and the ceramic structure is damaged irreversibly. A fan-cooled aluminium heatsink or a water block is mounted on the hot surface, and the block to be cooled on the cold surface, with thermal paste.

Key features:

     High current 15A class: It is the high power member of the TEC1-127xx family; with up to 15A and approximately 231W power consumption at Vmax it is suitable for cooling small volumes quickly.

     Cooling and heating in one plate: Reversing the current swaps the cold and hot surfaces; in setups such as incubators or test cabinets the same plate both heats and cools.

     Standard 40mm x 40mm fit: It has the common 40mm x 40mm Peltier size; it is used with CPU coolers, water blocks and Peltier mounting kits of the same size.

     No moving parts: It uses no compressor or gas; it runs silently without vibration and can be mounted at any angle.

     Leads attached: Its red (+) and black (-) leads of about 15cm are attached to the plate; the ends connect directly to a power supply or a thermostat relay.

Usage information:

•  Apply thermal paste and place a fan-cooled aluminium heatsink or water block on the hot surface and the block or plate to be cooled on the cold surface; clamp the plate between the two blocks with even screw pressure.
•  Connect the red lead to +12V and the black lead to GND. The power supply must deliver high current; use a 12V supply able to deliver up to 15A and thick wires.
•  To identify the cold surface, power the plate for a few seconds while mounted on the heatsink, compare the surfaces and mark the cold one; the printed side does not mean the same thing in every production batch.
•  To keep the temperature constant, switch the plate on and off with a thermostat module and relay.

Application areas:

•  Mini fridge and freezer setups
•  Mini air coolers and cold air blowers
•  Water dispensers and drink coolers
•  Car and camping cooler boxes
•  Dehumidifiers (collecting water by condensation)
•  Incubator heating and cooling
•  Aquarium water cooling
•  CPU, laser diode and camera sensor cooling
•  Temperature test cabinets and laboratory temperature control
•  Thermoelectric generator experiments producing small electric power from a temperature difference

Points to consider:

•  Cooling of the hot surface is mandatory. If it is not cooled, the product will burn within seconds. Do not power the plate for more than a few seconds without a heatsink.
•  Do not exceed Vmax 15V and Imax 15A. The current drawn at 12V is high; thin wires, weak adapters and small connectors heat up.
•  The heat to be removed from the hot surface is the heat pumped from the cold surface plus the electrical power drawn by the plate; size the heatsink accordingly.
•  The ceramic plate is brittle; tighten the mounting screws crosswise and evenly, do not overtighten and do not bend the plate.
•  Humidity in the ambient air condenses into water droplets on the cold surface; protect nearby circuits and wire ends from water.
