The invention discloses a multi-temperature-zone temperature control device based on a large-temperature-difference environment. The multi-temperature-zone temperature control device is mainly composed of a metal cold conduction structure, a high-stability temperature control structure and a test piece mounting plate. The high-stability temperature control structure and the test piece mounting plate are of a multi-partition independent temperature control structure; the device is placed on a low-temperature platform, the low-temperature platform serves as a cold source, multi-temperature-areahigh-precision temperature control over test equipment on the test piece mounting plate is achieved, and the requirement for maximum temperature difference control between the working temperature of the test equipment and the low-temperature platform can be met. 本发明公开了一种基于大温差环境的多温区控温装置，主要由金属导冷结构、高稳定性温度控制结构以及试件安装板组成。高稳定性温度控制结构以及试件安装板采用多分区独立控温结构，本发明装置放置在低温平台上，以低温平台作为冷源，实现试件安装板上试验设备的多温区高精度控温，可满足试验设备工作温度与低温平台间的极大温差控制。
