What is an electronic refrigerator?
Electronic refrigerator, also known as semiconductor refrigerator, is compact and has no mechanical refrigeration process. Widely used in automobiles, airplanes and other mobile refrigeration platforms. Electronic refrigerator is a product with completely different refrigeration principle from ordinary refrigerator. It is known as the world's smallest "compressor" by using a 40 mm square and 4 mm thick semiconductor chip through efficient ring double-layer heat pipe heat dissipation and heat conduction technology and automatic pressure transformer control technology. Because semiconductor refrigerator belongs to electronic physical refrigeration, it uses refrigeration working medium and mechanical moving parts, thus completely solving the application problems such as medium pollution and mechanical vibration that mechanical refrigeration refrigerator can't solve. It has more remarkable energy-saving characteristics in small-capacity low-temperature refrigerator and is of great development and popularization value.
What is the principle of electronic refrigerator?
The Peltier effect in the principle of electronic refrigerator originated from the practice of connecting copper wire to DC power supply. After connecting copper wires, one end will become hot and the other end will become cold, which is the earliest origin of electronic refrigerators. The semiconductor refrigerator used in /pp electronic refrigerator belongs to the category of physical refrigeration. It mainly works through mechanical moving parts. This working mode can deal with the problems of medium pollution and mechanical movement to the greatest extent, improve the working efficiency of small electronic refrigerators, and realize more energy-saving and efficient work.
What if the electronic refrigerator doesn't cool?
1, check whether the power supply is plugged in, whether there is a problem with the contact of the power plug, or whether the plug board itself is powered off.
2. If there is nothing wrong with the power check, it is necessary to check whether the fan of the electronic refrigerator is rotating. If the fan doesn't turn, the refrigerator is prone to problems if it can't dissipate heat immediately.
3. The fan is normal, and then check whether the refrigerator current is normal. You need to check the voltage at the Peltier connection. If the voltage is 12V or above, the fuse and PCB are in good condition. In this case, it is recommended to replace a new Peltier element. If there is no voltage, it can be determined that the fuse of the fuse is damaged, and the fuse can be replaced.
4. To rule out the above possibilities, you can also check whether the cooling surface of the electronic refrigerator is close to the aluminum plate. In addition, it should be noted that the hot end of the radiator must not be close to the cooling surface and aluminum plate.
5. Check the refrigeration parts of the electronic refrigerator to see if they are damaged. If there is a problem, you can go directly to a professional place to replace it.
6. Another thing that people tend to overlook is the service life of the electronic refrigerator. If the electronic refrigerator is used for a long time, the reason for not cooling may be that the service life of the electronic refrigerator has come to an end.
The above is the principle of electronic refrigerator brought by Bian Xiao. The whole content of the reason why the electronic refrigerator does not cool.
