The electronic refrigerator is a refrigeration system mainly used in mobile vehicles such as automobiles and airplanes. It is favored by consumers because of its portability, and the working principle of the electronic refrigerator is different from that of other ordinary refrigerators. What is it? What if the electronic refrigerator is not cooling? Let's take a look at the decoration home decoration network Xiaobian.
What is an electronic refrigerator?
The electronic refrigerator is also called a semiconductor refrigerator, which is small in size and has no mechanical refrigeration process. Widely used in mobile refrigeration platforms such as automobiles and airplanes. The electronic refrigerator is a completely different product from the ordinary refrigerator in the principle of refrigeration. It uses a 40mm square and 4mm thick semiconductor chip to achieve cooling through high-efficiency annular double-layer heat pipe heat dissipation and conduction technology and automatic variable pressure flow control technology. It is hailed as the world's smallest "compressor". Since the semiconductor refrigerator is an electronic physical refrigeration, the refrigerant working medium and the mechanical moving parts are used at all, thereby completely solving the application problems that the mechanical refrigeration refrigerator such as the medium pollution and the mechanical vibration cannot solve, and is more remarkable in the small-capacity low-temperature refrigerator. The energy-saving features are extremely valuable for development and promotion.
What is the principle of an electronic refrigerator?
The Peltier effect in the principle of electronic refrigerators was first practiced by connecting the copper wire to the DC power supply. After the copper wire is turned on, one end will become hotter and the other will become colder. This is the earliest origin of the electronic refrigerator.
The semiconductor refrigerator used in the electronic refrigerator belongs to the category of physical refrigeration. It mainly works by mechanical moving parts. This working mode can deal with the problems of medium pollution and mechanical movement to the greatest extent, and improves the working efficiency of the small electronic refrigerator. Achieve more energy-efficient and efficient work.
What if the electronic refrigerator is not cooling?
1. Check if the power supply is plugged in, if there is any problem with the power plug contact, or if the card itself is powered off.
2. If there is no problem with the power check, it is necessary to check whether the fan of the electronic refrigerator is rotating, the fan does not rotate, and the refrigerator cannot be cooled immediately, which is prone to problems.
3, the fan is normal, then check whether the current of the refrigerator is normal, the current is not normal, you need to check the voltage of the Peltier connection, the voltage is 12V or above, indicating that the fuse and PCB are intact. In this case, it is recommended to replace the new Peltier component. If there is no voltage, then it can be determined that the temperature fuse of the line is damaged, and the fuse can be replaced.
4. Excluding the above possibilities, it is also possible to check whether the sealing surface of the electronic refrigerator is tightly attached to the aluminum plate. In addition, it should be noted that the hot end of the heat sink must not be close to the cooling surface and the aluminum plate.
5. Check the refrigeration components of the electronic refrigerator to see if they are damaged. If there is any problem, you can go directly to the professional place for replacement.
6. Another thing that people tend to overlook is the service life of electronic refrigerators. If the electronic refrigerator has been used for a long time, the reason for not cooling may be that the service life of the electronic refrigerator reaches the end.
The above is the principle of electronic refrigerator brought by Xiaobian. The whole reason why the electronic refrigerator does not cool, I believe that everyone has a basic understanding of the principle of electronic refrigerator after reading this article, if you want to know more about decoration consultation, please click to enter the decoration knowledge channel .
