Alinan 3 Pcs. Tec1-12703 Semiconductor Refrigeration Tablets Tec1-12703 12V 12A Product Details Product Information: Chip Model: TEC1-12703 Dimensions: 40*40*4. 3mm+0. 1 Maximum Voltage: 15.8V Maximum Current: 3A Recommended Voltage: 12V Maximum Temperature Difference: 65C Maximum Cooling Capacity: 26W Assembly Pressure: 85N/cm2 Working Environment: temperature range 55C 85~C (excessive ambient temperature will directly affect cooling efficiency) Single Weight: 22g Wire Specifications: wire length 115mm The side with the words is the cooling side The wordless side is the cooling side A radiator or a water cooling device must be installed on the heat dissipation surface, otherwise it will burn out. (Note: Whether it is water cooling or air cooling, thermal grease must be applied) The cooling effect will be achieved when the power is turned on during the test without heat dissipation. The power should be unplugged immediately within 1 second. Otherwise, it is easy to burn out the cooling chip. Please test carefully, do not use this method for beginners to test. ?They are Lightweight and durable, Suitable for manufacture in small size. ?Semiconductor coolers are a form of solid state cooling that incorporates both semiconductor technologies and electronic assembly techniques. ?TEC1-12703 Thermoelectric Cooler Cooling Plate Module 12V 3A. ?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. ?These devices must be used in conjunction with a heat sink to avoid burned.
