Using of the technologically advanced power adjustment modules,
heating cage adopts temperature control instruments with PID self-tuning and resistance heating, make the temperature control more accurate and safer.
The testing temperature of the specimen is mainly controlled by the temperature sensor of the automatic temperature control instrument of temperature control system.
The infrared heating cage size is 2000mm×2500mm,
It is used to achieve a high temperature of +150℃.

The sink tube material is red copper plate and red copper tube,
the structure is ribbed tube type.
The outer surface is wrapped with mirror stainless steel reflective screen, the inner surface is painted with special black paint for spaceflight F26.
The black paint absorption rate is 0.94, the reflectivity is 0.87.
The heat sink is placed in a vacuum container to provide a cool black background for specimen testing.

The vacuum tank door is opened and closed by shifting to the left side.
It adopts the structure of guide rail rollers.
The translational structure transports the vacuum tank door to the foretelling position,
The door is transported by the sealing movement structure to the sealing ring and the end face of the vacuum tank flange,
The door is closely attached to the flange of the vacuum tank by the locking mechanism to reach the condition of being able to draw a vacuum.

The door adopts electric driving method to realize automatic control.

The temperature sensor is attached to the test aluminum ingot load to detect high vacuum.

With local control and remote computer control.
