Abstract

The invention relates to a temperature control device and method based on a TEC. According to the device, a heat radiation fin, TECs, a photoelectric device, a heat transfer plate, a box body, and a constant temperature room are combined. The method comprises the steps that: (S1) a temperature sensor collects the temperature of the heat transfer plate and the temperature of the constant temperature room and transmits temperature signals to a control component, (S2) the control component controls the TECs to carry out heating or cooling according to the temperature signals and controls a heat radiation fan to run or stop, and (S3) the steps (S1) and (S2) are repeated until the temperature of the heat transfer plate collected by the temperature sensor is in an optimal working temperature of the photoelectric device such that the photoelectric device is in a stable and uniform temperature environment. Through designing a closed box body structure, with the constant temperature room as a target control area, with a heat insulating material as a side wall, a constant temperature room structure is designed, thus the photoelectric device is in a constant temperature environment, heat loads are concentrated, the efficiency of temperature control is higher, the precise control of the temperature of the constant temperature room is realized, and a problem that only a local temperature of the photoelectric device meets requirements and an environment temperature does not meet requirements is avoided.

Description

technical field [0001] The invention relates to the technical field of photoelectric device temperature control, in particular to a TEC-based temperature control device and method. Background technique [0002] With the advancement of optoelectronic technology, optoelectronic devices such as lasers and fiber optic gyroscopes are used more and more widely. However, since optoelectronic devices such as lasers and fiber optic gyroscopes are temperature sensitive components, working at high or In the low temperature environment, it is necessary to configure a special temperature control device or system. [0003] The temperature control method based on TEC has been applied in the temperature control device or system of optoelectronic devices. CN105786047A discloses "a semiconductor laser temperature control system based on TEC". The temperature of the semiconductor laser. The main problem of this method is that the laser is exposed to the air. Under extreme temperature conditio...
