TEC1-12706 Semiconductor Refrigeration Chip Water Dispenser Refrigeration CPU Electronic Refrigerator Special
The working state of the refrigeration chip is to cool and heat at the same time. During operation, the heating surface must be well cooled. It is strictly prohibited to power on for more than 2 seconds without heat dissipation, which may cause overheating and burning. The buyer shall bear the responsibility!!!
Note:Rated voltage 12V
Lead length: approximately 30CM
The working state of the refrigeration chip is to cool while heating. During operation, the heating surface must be well cooled, and it is strictly prohibited to power on for more than 2 seconds without heat dissipation, which may cause overheating and burning. The buyer shall bear the responsibility!
When installing a radiator, it is necessary to apply thermal grease.
Some have a literal meaning of cold noodles, while others have a literal meaning of hot noodles.
Customers who place orders should carefully read the following content The working state of the refrigeration chip is to cool while heating. During operation, the heating surface must be well cooled, and it is strictly prohibited to power on for more than 2 seconds without heat dissipation, which may cause overheating and burning. The buyer shall bear the responsibility! For buyers who want to test the quality of the received goods, a battery can be used for testing The specific method is to hold the refrigeration chip with one hand and press the wire of the refrigeration chip onto the two ends of the battery with the other hand. If you can feel one side slightly cold and the other slightly hot, it means that the refrigeration chip is good |
How to distinguish between hot and cold surfaces
The rated voltage is 12V, the rated current is 4.5A, approximately 50-60W, the temperature difference can reach 60 degrees Celsius, the external dimensions are 4 X 4 X 0.4Cm, and the weight is about 25 grams. Its working characteristic is to cool while heating at the same time.
The temperature difference between the hot and cold sides is 68 degrees (as long as the temperature of the hot side remains below 68 degrees, the temperature of the cold side can be controlled between 0 and -68 degrees or lower)
When connected to a 12V power supply, there will be a temperature difference between the two sides of the refrigeration unit, with one side being cold and the other side being hot,Never power on the refrigerator for a long time without a radiator, otherwise it may cause internal overheating and burnout of the refrigerator.
This product can be applied to various cooling scenarios (such as hot and cold water dispensers, computer CPUs, graphics card cooling, etc.)
Experts can also apply it to other purposes and fields such as electronic refrigerators, electronic cooling headbands, electronic cooling helmets, electronic hot and cold cups, etc,Used for computer cooling, a voltage of 5 volts is sufficient, which means that any red or black wire in the power cord of the computer is 5 volts, with the red wire being the positive pole and the black wire being the negative pole (the cooling element is also like red positive and black negative)
Installation and Usage
The installation and use of refrigeration chips are very simple. Before installation, prepare some thermal conductive silicone grease, then find a dry battery and connect it to the two leads of the refrigerator. You can feel one end clearly cool while the other end heats up. Remember the polarity of the leads and determine the cold and hot ends of the refrigerator. If you want to achieve a larger cooling capacity, it is recommended to use a two-stage cooling method, which involves stacking two pieces together, with the cooling surface of the upper piece absorbing the heat generated by the lower piece. Experimental results have shown that two-stage cooling is much better than single-stage cooling. If conditions permit, a three-stage cooling can be chosen, of course, with the support of a high-power power supply.
