Description
Technical Field
The invention relates to the technical field of refrigeration, in particular to a special heat exchange device for semiconductor refrigeration equipment.
Background
The semiconductor refrigerator is a device for producing cold by using the thermo-electric effect of a semiconductor. When two different metals are connected by a conductor and direct current is applied, the temperature at one junction is reduced and the temperature at the other junction is increased. If the power supply is reversed, the temperature at the junction will change inversely. This phenomenon is known as the peltier effect, also known as the thermo-electric effect. The thermoelectric effect of pure metals is small, and if one N-type semiconductor and one P-type semiconductor are used instead of metals, the effect is much larger. After the power supply is switched on, electron hole pairs are generated near the upper contact, the internal energy is reduced, the temperature is reduced, and heat is absorbed to the outside, namely the cold end. The other end is called hot end because the electron hole pair is compounded, the internal energy is increased, the temperature is raised, and heat is released to the environment. The temperature difference and cold quantity generated by a pair of semiconductor thermoelectric elements are very small, and the practical semiconductor refrigerator is formed by combining a plurality of pairs of thermoelectric elements in parallel and series, and is also called a thermopile. Therefore, in a long-term operation state of the semiconductor, the temperature generated on the conducting plate for connecting the N, P type semiconductor is larger than the temperature difference between the temperature on the conducting plate at the connecting end of the N, P type semiconductor and the temperature on the conducting plate at the center, so that the temperature transmitted from the conducting plate to the conducting insulating plate is not uniform, the damage of the refrigeration module is easily caused, the material of the conducting insulating plate is generally ceramic material, and particularly, the cracking damage of the conducting insulating plate is easily caused when the power supply is switched between positive connection and negative connection.
