Okay and thank you for the image, but what are their translations of the wording in the image.
Being the dumb tanker that I am, I am going to assume the image color code means something. My assumption since I cannot read Mandurian is that the orange box is the Thermal Management System ( TMS) that is for cooling the electronics of the vehicle. The Purple is the power unit or combustion engine, The green is the armored hull, the yellow is the track & roadwheels, the white bar shown through the Turret ring are the torsion bars, and the white assembly in front of the purple power unit (engine) is the transmission or a generator.
But again I cannot read Mandurian and these are my assumptions based my just a couple decades in tanks.
Many modern armor fighting vehicles with complex electronic components require cooling systems to reduce the build-up of heat that emanates from these electronic components. Many if not all of these electronic components are a sealed box to operate in a military vehicle that exposes them to hydraulic fluids, oils, engine heat, etc. In the M1A2 SEP tanks there is a TMS system mounted in the bustle rack. An external mount, and here it appears the Norinco developers built the TMS as a part of the body. That in itself is an interesting trade off with the internal volume of the vehicle.
