TEC1-12715 Heatsink Thermoelectric Cooler Cooling Peltier Plate Module True 15A

Description

TEC1-12715 - Superior efficiency & performance compared to 12705
(if used correctly)
There are many TEC1-12715's that are 'fake' in the sense that they have less thermoelectric material and are actually 6 or 8 amp units with a 15 print on them. We test each batch and have taken a lot of money and effort to obtain and keep in stock the best (for the price) 12715's that pull the correct amperage and pump more joules than the competition. That is why the price may be a little higher. I can honestly say this is one of the best Peltiers for the price you could get. That said everyone's needs are different, and if you are not sure if a 12715 is appropriate for your needs, send us a message and we'll help you sort it out. There are indeed situations where a 12715 will work worse than a 12706, so if you need advice, don't hesitate to ask, we specialize in refrigeration tech and can help you.
Shipping is a flat .50 for the total order, regardless of how many chips you buy - so stock up, the cost on thermoelectric compounds keeps going up!
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.
We sell 40*40mm
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.
We also carry some rare Peltier chips with larger 50*50mm ceramic or aluminum plates, as well as TEC1-12710 with ultra-thin Copper plates.

Recommended Heat Sinks
In order to get the most out of your TEC1-12715 you should be attaching it to a very capable radiator. After much testing and pondering, we can highly recommend
this solid copper, compact, powerful turbo fan powered heat sink (click)
.
It can be run on the same power supply as the Peltier chip with the black & red wire, or can be controlled with a PWM, or a variable resistor between the blue and black wire.
PWM Fan Speed Controller for 4-pin heatsink fans
We carry the rare
ZF1X4-1707 PWM fan speed controller (click)
which will automatically modulate your heatsink fan with the included temperature probe.
Highly recommended, to use with a heat sink of your choice (even if you don't buy ours).
Enjoy!
