Custom Refrigeration Sheet – Semiconductor Refrigeration Sheet
The working principle of semiconductor refrigeration sheet is based on Peltier’s principle. This effect was first discovered by j.a.c. Peltier in 1834, that is, when the circuit composed of two different conductors A and B is connected with direct current, some other heat will be released at the joint in addition to Joule heat, while the other joint absorbs heat, Moreover, this phenomenon caused by Peltier effect is reversible. When changing the current direction, the exothermic and endothermic joints also change. The absorbed and released heat is directly proportional to the current intensity I [a], and is related to the properties of the two conductors and the temperature of the hot end.

*How to judge the quality of semiconductor refrigeration chip
The quality of semiconductor refrigeration chip can be judged by measuring its resistance, current or voltage with a multimeter. The normal range of resistance of semiconductor refrigeration chip is 0-0.05 Ω, the normal range of current of Hangzhou semiconductor refrigeration chip is 0-0.09 a, and the normal range of voltage of semiconductor refrigeration chip is 0-0.1 v.
Semiconductor refrigeration sheet
1. First, connect the two test wires of the universal pen to the semiconductor antifreeze sheet and the grounding wire, and separate the red wire from the black wire. The red line is the positive electrode of the frozen semiconductor chip, and the black line is the negative electrode of the frozen semiconductor chip.
2. Next, decide whether to measure the AC or DC of the semiconductor freezing sheet to check the quality. For DC voltage, adjust the gear in the DC area as shown and connect it to the measuring line.
3. If the line is 220V, black line will be used. When measuring the AC current of semiconductor refrigeration chip, the gear must be adjusted to the AC area. DC and AC correspond to two different gears respectively.
4. Insert the red and black test lines into the line difference. The value read by the multimeter is 00.4a. There is a digital display, which is the current number of ordinary Peltier circuits, which proves that Peltier is good.
