Small tec temperature control equipment

Abstract

The invention discloses a small-sized TEC temperature control device. By setting the first upper semiconductor refrigeration sheet group, the second upper semiconductor refrigeration sheet group, the first lower semiconductor refrigeration sheet group, and the second lower semiconductor refrigeration sheet group, and setting the upper compartment cavity and the lower compartment, so that the temperature control mechanism can make the temperature in the upper compartment and the lower compartment equal, and the temperature in the upper compartment or the lower compartment is at the same level as the temperature in the storage cavity. Between the temperature in the storage chamber and the external temperature, the temperature in the storage chamber is the target control temperature, which effectively reduces the difference between the temperature in the storage chamber and the temperature in the upper or lower compartment, effectively ensuring the accuracy of temperature control and maintaining the temperature in the storage chamber. The accuracy of the temperature improves the accuracy of the temperature in the TEC temperature control equipment.

Description

technical field [0001] The invention is specifically a small TEC temperature control device, and relates to the related fields of temperature control devices. Background technique [0002] At present, TEC temperature control equipment is generally a high-performance temperature control system realized on the basis of semiconductor refrigeration chips using the principle of semiconductor refrigeration, which generally has high control accuracy, high stability, and long life performance. However, for some small TEC temperature control equipment, it often requires extremely high precision of the internal temperature. In actual use, although the temperature control accuracy is high, due to the temperature difference between the inside and the outside, this temperature difference effect will make the temperature control The temperature inside the equipment changes, especially when the temperature difference is large or the external temperature is changing, because it is difficult...

However, for some small TEC temperature control equipment, it often requires extremely high precision of the internal temperature. In actual use, although the temperature control accuracy is high, due to the temperature difference between the inside and the outside, this temperature difference effect will make the temperature control The temperature inside the equipment changes, especially when the temperature difference is large or the external temperature is changing, because it is difficult to ensure a constant balance between the heat generated by the cooling plate and the heat loss due to the temperature difference, which will lead to certain fluctuations in the internal temperature, and This fluctuation is often affected by the angle of temperature difference, which in turn affects the control accuracy
