Double Layer Battery Thermal Cycling Test Chamber


2.1 Cooling System
1The refrigerating system uses environmentally friendly refrigerant R404a (R449a as option) and R23. Adopting binary low temperature circuit system design, it is convenient to use different compressors for work in different temperature regions.
2Temperature and humidity control using P.I.D + S.S.R system coordinated control with the same channel. It has the function of automatic calculation, which can immediately modify the temperature change conditions to make the temperature control more accurate and stable.
3High-precision controllers of temperature. The relative temperature performance is accurately set and displayed with a resolution of 0.1 ℃.
2.2 Temperature System
1Temperature system using Nickel-chromium alloy high-speed heating electric wire;
2High temperature system is completely independent;
3Contains four temperature sensors to detect the surface temperature of the battery and display it on the controller
2.3 Control System
Temp. SensorHigh precision PT100 Platinum resistance
Display Functiona. Temp. Setting (SV) Practical (PV) value can be displayed directly
b. Display numbers, paragraphs, remaining time and cycles, running time
c. Program editing and graphic curve display,
d. Fixed or program operation status display,
Interfacea. RS-232 or R485 port design
b. Connected to computer
c. Monitor and remote control by computer and Ethernet
2.4 Protection System
1Protection for Electrical leakage
3Compressor overvoltage and overload
4Heater short circuit

Heating SystemNichrome stainless steel heater
Testing holeDiameter 150mm, there are 2 holes for cable routing for each chamber
EvaporatorFinned tube heat exchanger
Dry filterAbsorb the residual moisture and acidic substances in the refrigerant of the refrigeration system, and filter out solid particles, copper shavings, etc. in the system to protect the normal operation of the expansion valve and capillary tube, and prevent ice blocking and dirty blocking.
Door handleNon-reaction, explosion-proof door handle, easy to operate, safe and reliable
Insulation100mm polyurethane rigid foam and 100mm high density glass fiber cotton
Insulation systemFilling the insulation area with ultra-fine glass fiber;
Machine connection parts are made of non-metal resistant high and low temperature materials, which effectively reduces the temperature conduction;
Door seal is made of refined silicone rubber, which is more reliable seal;
Observation windowDouble-layer vacuum-strengthened glass;
Heat-resistant defrosting on the inside with adhesive sheet conductive film, which can clearly observe inner chamber.
