Cooling System Basics
What are the four main purposes of a vehicle's cooling system?
What is reach operating temperature quickly, maintain operating temperature, remove excess heat, and provide passenger comfort?
What are the three types of heat transfer used in vehicles?
What is conduction, convection, and radiation?
What does the radiator do in the cooling system?
What is removes heat from coolant using airflow and heat exchange?
What is the ideal operating temperature range for lithium-ion batteries?
What is 60°F to 95°F (16°C to 35°C)?
What system removes heat and humidity from the air?
What is the air conditioning system?
Why is it important for a vehicle to reach operating temperature quickly?
What is to reduce energy waste and improve efficiency and emissions?
What type of heat transfer occurs through direct contact?
What is conduction?
What is the function of the radiator cap?
What is maintains pressure and allows coolant to move to/from recovery tank?
What cooling method places components directly in e-thermal fluid?
What is direct immersion cooling?
What is the function of the cabin air filter?
What is removes contaminants from cabin air and improves air quality?
What happens if an ICE vehicle runs too cool or too hot?
What is running too cool causes rich fuel mixture; too hot can warp metal and damage gaskets?
What type of heat transfer involves fluid movement?
What is convection?
What component circulates coolant through the system?
What is the water pump?
What are e-thermal fluids and why are they used?
What is synthetic fluids with dielectric properties for safe and efficient cooling?
What is the difference between a resistive heater and a heat pump?
What is resistive heaters generate heat; heat pumps transfer heat efficiently?
What component helps regulate the engine temperature by opening and closing?
What is the thermostat?
What type of heat transfer uses electromagnetic waves?
What is radiation?
What is the purpose of the coolant recovery tank?
What is stores excess coolant and prevents air contamination?
What happens if you charge a lithium-ion battery below freezing?
What is lithium plating and permanent battery damage?
What does the orifice tube do in an A/C system?
What is reduces refrigerant pressure before entering the evaporator?
What are the consequences of overheating in EVs and ICE vehicles?
What is engine damage, reduced efficiency, possible fire, and system failure?
How do heat exchangers use these types of heat transfer?
What is by transferring heat between fluids using conduction, convection, and radiation?
What causes a radiator hose to collapse after engine shutdown?
What is a faulty vacuum valve in the radiator cap?
What components in EVs require thermal management?
What is traction batteries, e-motors, power electronics, inverters, and fast chargers?
Why is refrigerant recovery and recycling important?
What is to prevent environmental damage and comply with legal regulations?
