Teach-in board for engine cooling system

Functional features
1. Anatomical treatment of each key part of cooling (such as: water pump,
thermostat, etc.), spraying different colors on each profile, and
comprehensively displaying the internal and external structure of the engine
cooling system.
2. The teach-in board panel adopts high-grade aluminum-plastic panel that is
resistant to impact, pollution, fire and moisture, and the surface is treated
by special process spraying primer; The panel is printed with a color circuit
diagram and working principle diagram that will never fade; Students can
intuitively compare the structural schematic diagram and physical object of the
engine cooling system to understand and analyze the working principle of the
engine cooling system.
3. LED lights of different colors are installed on the panel of the teaching
board, and the flow direction of coolant in the large, small and mixed cycles
can be dynamically demonstrated through the sequential flashing of LED lights.
The teach-in board panel is equipped with a detection terminal, which can
directly detect the electrical signals of each circuit element of the cooling
fan system, such as resistance, voltage, current, frequency signal, etc. on the
panel.
4. The panel part of the teaching board adopts 1.5mm cold plate stamping
forming structure, which has beautiful appearance; the bottom frame part adopts
steel structure welding, the surface adopts spraying process, with self-locking
caster device, and the base of the teaching board is equipped with a desktop of
about 40cm, which is convenient for placing data, testing instruments, etc.
5. The teaching board works with ordinary 220V AC power supply, which is
converted into 12V DC power supply by internal circuit voltage transformation
rectification, without battery, reducing the trouble of charging, and 12V DC
power supply has anti-short circuit function.
