AI Technical Summary

Technical Problem

Existing technologies cannot achieve rapid local heat transfer and high-precision temperature control in a vacuum environment. Independent zone temperature control results in insufficient thermal stability and control speed, which cannot meet the requirements of high thermal stability and temperature control response speed for precision instruments.

Method used

A temperature control device with unidirectional active heat transfer in a square partition is adopted. Through the combination of a square electric heating radiation plate and a semiconductor cooling chip, the heating power and the voltage of the semiconductor cooling chip are adjusted by a temperature controller to realize unidirectional active heat transfer from the high-temperature unit to the low-temperature unit. Combined with an annular circulating cooling water chamber to provide a cold source background, temperature consistency and rapid response are ensured.

Benefits of technology

It achieves rapid directional heat conduction and high-precision temperature control, improving temperature control efficiency and stability. It can quickly respond to local thermal interference, ensuring temperature uniformity and temperature control within the set range.
