In fact, the application of semiconductor peltier is very strict. In view of this point, today we will explain to you about the medical application of thermoelectric peltier. Let's introduce Hangzhou semiconductor peltier for you.
 
There is a fundamental difference between semiconductor peltier and traditional refrigeration chip. It does not require refrigerants, mechanical equipment and piping. As long as direct current is supplied to the semiconductor cooler, its cold end will be cooled down quickly and easily without noise and pollution. Moreover, it is small in size and can be used for many special occasions. The temperature control is completely accurate.
 
In principle, when there is a current passing cycle in a thermocouple pair formed by n-type semiconductor data and p-type semiconductor data connection, heat transfer will occur between the two ends, and heat will be transferred from one end to the other, and then there will be a temperature difference to form the cold and hot ends. However, the semiconductor itself has a resistance. When an electric current passes through a semiconductor, heat is generated, and then heat transfer is affected. In addition, the heat between the two plates will also be reversed through the air and the semiconductor data itself. When the temperature difference between the cold end and the hot end reaches a certain value, when the two heat transfers are equal, they will reach an equilibrium point, and the forward and reverse heat transfer will cancel each other. At this time, the temperature at the cold and hot ends will not continue to change. In order to achieve a lower temperature, heat dissipation and other methods can be used to reduce the temperature of the hot end.
 
Semiconductor refrigeration sheet is widely used. For example, in the medical field, products such as cryology, cryotherapy and biochemical instruments are successfully developed through the use of semiconductors. In electronic technology, cooling and heating semiconductor equipment, photomultiplier tube, infrared detector, etc. It can also be realized by deep cooling with semiconductor peltier. Therefore, whether in biomedical or electronic technology, the use of semiconductor peltier has a very broad prospect
