AI Technical Summary

Technical Problem

Existing temperature control devices are time-consuming to change samples in low-temperature mechanical tests of ice blocks. Opening the cover causes low-temperature gas to escape, and the re-cooling time is long. In addition, multi-station devices are costly and not well sealed, which affects the efficiency of the test.

Method used

The temperature control device includes a temperature control mechanism and a heat preservation mechanism. It achieves rapid sealing and material flipping through sealing components and rotation control components. Combined with water cooling structure and refrigeration equipment, it forms a closed loop to ensure temperature stability and efficiency.

Benefits of technology

It enables rapid sample change, reduces low-temperature overflow, improves detection efficiency, reduces energy waste, and ensures temperature control stability and test efficiency.
