Abstract

Provided in the invention is a temperature control structure comprising a heat radiation structure, a temperature control execution unit and a temperature detection unit. The temperature control execution unit includes a semiconductor refrigeration plate; and the temperature detection unit includes a thermistor. The temperature control structure is characterized in that the lower surface of the semiconductor refrigeration plate is a thermal surface and is in conduction contact with the heat radiation structure; and the upper surface of the semiconductor refrigeration plate is a cold surface and is in conduction contact with a temperature controlled element. And thermal transmission between the semiconductor refrigeration plate and the thermistor is realized by an aluminium nitride circuit wafer. Under the circumstance that compatibility of the semiconductor refrigeration plate and the thermistor is guaranteed, accuracy of temperature detection of the semiconductor refrigeration plate by the thermistor is guaranteed, thereby guaranteeing high-precision temperature control.

Description

technical field [0001] The invention relates to a temperature control structure, in particular to a temperature control structure suitable for the technical field of heat dissipation of electronic equipment. Background technique [0002] Temperature changes have a great influence on the performance parameters of some optical devices, especially photonic filters and light sources. In microwave photonics applications, it is important to consider temperature control measures for optical devices. Generally, there are two ways to eliminate the influence of temperature changes on the performance of optical devices: one is to establish the corresponding relationship between device performance and temperature, and to compensate through models; the other is to eliminate the influence of temperature changes through temperature control structures, so that the devices are always Work at a fixed temperature. [0003] Traditional temperature control devices use air-cooled or liquid-cool...
