AI Technical Summary

Technical Problem

Existing technologies have low cooling efficiency and uncontrollable cooling rate, which cannot meet the production requirements of high efficiency and fast cycle time. In addition, there are risks of condensation and uneven cooling of the workpiece surface during the cooling process.

Method used

An independent cooling device is adopted, which combines a blower and a liquid cooling mechanism. Inert gas is used for forced cooling. A uniform airflow field is formed by multi-directional injection and guide plate design. Combined with phase change energy storage materials, the cooling process is stabilized to ensure the uniformity and efficiency of cooling.

Benefits of technology

It achieves an efficient and uniform cooling process, shortens cooling time, improves production efficiency, avoids condensation, and ensures the surface condition and quality stability of the workpiece.
