Where is the heater valve in Audi q7?

The Audi Q7 heater valve is under the hood, on the left side of the windshield, on the right side of the heater pipe, and the solenoid valve on the cylinder head. The working principle of a car heater is that the radiator in the heater is connected to the engine circulating water through the inlet and outlet pipes.

The car's heating system can heat the air inside the car or the air sucked into the car from outside the car to increase the temperature inside the car. There are many types of automobile heating systems. According to different heat sources, they can be divided into hot water heating systems, gas heating systems and exhaust gas heating systems. At present, hot water heating systems are mainly used in automobiles, and gas heating systems are mainly used in large vehicles.

The hot water heating system mainly consists of a heater core, a water valve, a blower and a control panel. The heater core consists of water pipes and heat sinks. The engine's cooling water enters the water pipe of the heater core, dissipates heat through the radiator, and then returns to the engine's cooling system. The water valve is used to control the amount of water entering the heater core, thereby regulating the heating amount of the heating system. When adjusting, it can be controlled through the adjusting lever or knob on the control panel. The blower consists of an adjustable speed DC motor and a squirrel cage fan. Its function is to blow air through the heater core and heat it into the car. Adjusting the speed of the motor regulates the air supply to the cabin.
