Sign is：Limiting device is provided with below the drawer body, babinet will not be completely disengaged when drawer body pulls out babinet.
8. a kind of it can simulate the equipment that is tested for the property under varying environment to memory bar, feature according to described in claim 1
It is：The cooling system includes water-cooling system and air cooling system, and the water-cooling system includes fluid reservoir, is provided with cycle
The water tank of pipeline is stored with coolant in fluid reservoir, offers liquid outlet and inlet on water tank, inlet on water tank and goes out
Liquid mouth is docked and connected by sealing poling box with fluid reservoir；The air cooling system is mounted on the front of water tank, including fan
Stent and fan group, fan group are mounted on the front of water tank by blower tray.
9. a kind of it can simulate the equipment that is tested for the property under varying environment to memory bar, feature according to described in claim 1
It is：Heating system, refrigeration system, humidity control system and the air circulation system of the environment simulator have respectively respectively
From PID micro processors, by respective PID micro processors set babinet in temperature and humidity or cause
Constant temperature and humidity state is in babinet.
10. carry out environmental simulation test to memory bar using the equipment described in claim 1-9, it is characterised in that：
First, memory bar to be detected is loaded：It is driven by pneumatic device, the drawer body of test device is pulled out automatically,
The memory bar to be tested is loaded on the inserted area of memory bar sample, is fixed by sample pressing plate, is then driven by pneumatic device,
The drawer body of test device is promoted to the box house of environment simulator automatically；
Then, lead to arrange parameter and carry out environmental simulation：Start environment simulator by control device to work, circulating fan
Start, heater strip heating, compressor start so that air quantity carries out internal cycle in babinet, sets the babinet of environment simulator
Internal temperature and humidity, and pass through PDL and control steady temperature so that babinet is in an analog temperature and the environment shape of humidity
State；
Finally, memory bar is tested：Under the simulated environment of setting, simulation use is carried out to memory bar, is obtained under set environment
Deposit the test result of item.
