　　Double layer high and low temperature alternating test chamber

　　1、 Product composition:Double layer high and low temperature alternating test chamberIt consists of multiple parts such as refrigeration system, heating system, control system, forced internal circulation system, smoke exhaust box, explosion-proof system, etc.

　　2、 Meet the standards:

GB/T2423.1-2008 (IEC60068-2-1:2007) Low temperature test method

GB/T2423.2-2008 (IEC60068-2:2007) High temperature test method

GJB150.3-1986 High temperature test;

CJB150..4-1986 Low temperature test;

GB/T 31485-2015 Safety Requirements and Test Methods for Power Batteries for Electric Vehicles

　　3、 Characteristics:

a) Streamlined appearance design: Both the box door and control panel adopt a curved streamlined design, which is aesthetically pleasing, safe and reliable, and will not harm the staff;

b) Bottom casters for easy movement: Four sets of universal wheels are installed at the bottom of the box, and the two front casters have self-locking function, which facilitates the movement and fixation of the equipment;

c) Single machine dual box design: This equipment adopts a single machine dual box design, with one test box on each side, and the control system and refrigeration system of the two boxes operate independently;

d) Front door secondary explosion-proof design: Explosion proof chains are installed on both the front and rear pressure relief doors of the box. When the battery explosion causes a huge impact force to open the equipment door, the explosion-proof chain plays a buffering role to prevent the door from opening or flying out, thus preventing secondary injury;

e) Reinforced hinge and explosion-proof lock design: The hinge connecting the explosion-proof door and the box body is made of reinforced 304 # stainless steel, and the door lock adopts a strong flat lock to ensure the safety of the equipment;

f) High quality insulation design: The insulation layer of this box is designed to be 100MM thick, using high-temperature resistant rock wool with extremely low thermal conductivity as insulation material, which has good insulation effect and minimal heat loss;

g) Side terminal design: Each box is equipped with 12 sets of copper terminals for testing on the side. The terminals are separated from the box by an insulated PTFE sleeve, which is sealed, energized, and will not leak electricity;

h) Side explosion-proof pressure relief design: Each box is equipped with an automatic explosion-proof pressure relief port on the side, which automatically releases pressure once it is sensed.
