[ (Simple Test Method for Refrigerator) ]
The operation method is: pinch the two sides of the cooling chip with one hand, and press the wires of the cooling chip on the two poles of the battery with the other hand (the red wire is pressed on the positive electrode, and the black wire is pressed on the negative electrode). If one side is slightly cold and the other is slightly warm, it means that the cooling plate is good and can work normally.

[ (Use of Cooling Sheet) ]

1. The working state of the cooling piece is that one side is cooling and the other is heating. When the cooling piece is working, the hot surface must be well dissipated, otherwise it will burn. It is strictly forbidden to energize the cooling piece for more than 2 seconds without heat dissipation. The energization of the cold and heat exchange must be performed when the hot and cold sides return to room temperature (generally more than 5 minutes), otherwise it will easily cause damage to the circuit of the refrigeration chip and rupture of the ceramic panel.


2. When the cooling chip is used for cooling, the red wire is connected to the positive pole of the power supply, and the black wire is connected to the negative pole of the power supply. The power supply requires a switching power supply with a ripple factor of less than 10%. Generally, the side of the ceramic panel where the wires are welded is the hot side. If the red wire is connected to the ne
