How does a car’s temperature blower work?

The heater core is a small radiator, usually about the size of a hardcover book. Hot coolant flows from the engine, through a hose, into the heater core and leaves through another hose. Air is warmed as it blows across the heater core as it travels to the vents, providing hot air.It is mounted inside the heater housing inside your car’s dash. The blower motor pulls air through the heater core, removing heat from the antifreeze circulating through it. The antifreeze then carries on to the water pump.

How does a car heater blower work?

The heater has an inlet and outlet which allows coolant to flow through the core. The blower motor will blow air through the heater core and to the passenger compartment inside your car. The heater control valve is a device that controls the flow of the hot engine coolant through the heater core.

How does temperature control work in a car?

Operated by an AC button on the dashboard, the air conditioning system is able to heat or cool air flowing into the car. Warm temperatures are controlled as they are in a standard car heater, but to cool the air, the car is fitted with an additional compressor under the bonnet that directs air to a condenser.

Where does hot air come from in a car?

The warmth from the engine goes from the radiator to the heater core, which basically acts as a heat exchanger. It allows coolant to flow through, and this flow of coolant is regulated by the heater control valve. As the engine's heat is carried by coolant into the heater core, the device starts to get warm.

How does a heater blower work?

Electric blower heaters work by converting electrical energy into heat energy through a resistive heating coil. The air is then moved over the heating coil using a fan; the air is then warmed and pushed out into the room which requires heating.
