Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler.
Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts
These devices must be used in conjunction with a heat sink to avoid burned
Each device is full inspected and tested
Fitted with 6-inch insulated leads
Size: 40mm x 40mm x 4mm
Operates : 0~12V DC and 0~4.5A
Operates Temperature: -30c to 70c
Max power consumption: 60 Watts
Net weight: 22g
Connected to a 12-volt power supply the cell will have a temperature differential between the two sides of about 20C(68F).
Important: do not conned the cell to a power supply for more than a few seconds without a heat-sink on the hot side otherwise there will be internal overheating and destruction of the Peltier cell.
This cooling Peltier cell is very simple to install and use. Before installation, you must provide a dry environment and allow for any condensation from the cold side to drain away and not to come in contact with the operating cell. Connect the two leads of the Peltier cell to an appropriate power supply and importantly, observe the correct lead polarity and attach an adequate heat-sink with a quality thermal conducting grease applied to the warm side of the cell; you will feel the warm side and the opposite cool side of the operating cell. It is important to identify both the correct lead polarity and the cooling/heating sides of the device. If you want a greater cooling differential, it is recommended to use two Peltier cells, namely, one stacked above the other with the hot side of the upper cell in contact with the cool side of the lower one; an experiment proved the two stacked cell cooling effect is much better than the single-stage. Similarly a three cell stack produces an even greater temperature differential but requires a larger capacity power supply support.
