12V 15A 225W Thermoelectric Cooler TEC Peltier Plate Module TEC1-12715 US

Description

TEC1-12715 - Superior efficiency & performance compared to 12705
(if used correctly)
Thermoelectric modules are magical devices that create a dramatic temperature differential between the two sides of their ceramic plates when electric current is applied. The most popular Peltier chip is the low-cost TEC1-12705. While it works for light duty applications, the 12715 is superior for few reasons:
The bimetallic junctions inside are twice as thick. This decreases the risk of failure and doubles the current you can use the device at.
The ceramic (alumina) plates are thinner than on the 12705. The thinner plates allow for better efficiency as the heat transfer is sped up.
Peltier efficiency increases (logarithmically) if you decrease the voltage used. That means that more heat is pumped (cold created) per watt of power used. Because the 12715 is rated for over twice the current of the 12705, the heat pumping ability is doubled.

Indium thermal interface pads that fit these perfectly, available here (click).
You can always run these at lower voltages for higher efficiency - as the current decreases, the coefficient of performance increases. At 12 volts the ΔT is almost 60°C. As you decrease the voltage and current draw, ΔT will decrease, but even at 1 volt there is a noticeable temperature difference, accompanied by the most efficient heat pumping you will find for this price.
Take your temperature control needs to a new level with solid-state.
These solid state devices are finding their ways into many creative applications. At Cold&Colder, we use them for custom-built server cabinet cooling. Since we use them ourselves, we can offer you advice on your application needs. Any questions are welcome. Bulk orders welcome, we have over 1,000 pcs in stock.
