• Type: TEC1-12715.68-140℉ SIZE:40MMX40MM
• A refrigeration plate is a type of refrigeration device based on the thermoelectric effect, which utilizes thermoelectric materials to generate a cooling effect under the action of current and temperature difference, thereby absorbing environmental heat and discharging it. Thermoelectric refrigeration technology has the advantages of small size, high power density, and no pollution, so refrigeration sheets are widely used in electronic equipment, biological refrigeration, precision instruments and other fields.
• The best working voltage is 12V, and the current is about 15A.
• Application scope: Large equipment such as freezers, refrigerators, air conditioners, refrigeration fans, and freezers
• 24-hour service: Heatlink Thermoelectric Cooler is always available for returns and exchanges if there are any issues, and Diymore will always be online to resolve your issues.

Product description
How to test Cooling Peltier Plate Module?

When we do not know the cold and hot surface of the cooling peltier plate module, we can connect the red line to the positive pole of the power supply, the black line to the negative pole, and to test the two ends of the cooling peltier plate module without heat dissipation. The heating side is hot and the cold side is cold. The time can not exceed 5 seconds, otherwise it is easy to cause the device to burn out due to the hot end temperature is too high.

Specification: Model:：TEC1-12715

• Size:40*40*4.2mm
• Number of component pairs:127pcs
• Internal resistance:3.0~3.3Ω(Ambient temperature 23±1℃, 1kHZ Ac test)
• Maximum temperature difference:△Tmax(Qc=0) Above 67℃
• Work current:Imax=12A(maximum voltage 15.5V 15A at startup)
• Rated power:Qcmax 109W
• Assembly pressure:85N/cm2
• Temperature range: -55℃～83℃ (Excessively high ambient temperature will directly affect the cooling efficiency)

• Note:
• Heat sink or water-cooled heat sink must be installed on the surface of the cooling peltier plate, otherwise it will burn out.
• Whether it is water-cooled or cold-air to apply heat-conducting silicone grease.

Cooling side and hearting side:

• One side with word is cooling surface,
• the another side without word is a heating surface.

The installation and use of the cooling peltier plate module:

• You can prepare a little heat conductive silicone grease and a dry battery before installation, then connected to the cooling peltier plate module two lead wires, you can feel one side obviously cool and the other side heat.
• Don't forget the polarity of the lead wire and determine the cold and hot end of the cooling peltier plate module.
• If you want to get a larger amount of cold making, it is suggested to adopt a two-stage cooling method by stacking up two pieces, and the cold surface of the upper one absorbs the heat of the following one.
• If there are conditions can be selected three-level, but there must be high-power power support.
