Heater Cores for Car Air Conditioning Systems

Car A/C Heater Cores

The heater core is a component of the car A/C system which heats the cabin and demists and defrosts the windscreen. Unlike the engine cooling radiator, which cools the A/C system's coolant, the heater core provides heat to the car cabin, ensuring thermal comfort to drivers and passengers when the ambient temperature is very low. Usually, the heater core uses the coolant as an energy source. In addition, it channels part of the heat produced by the engine into the car's cabin.

 

What is the role of the heater core?

The role of the heater core is to warm the cabin and improve visibility in cold conditions. The heater core is a heat exchanger located inside the HVAC loop after the evaporator and the ventilation blower. It is an air/water heat exchanger, so it uses the energy of the engine cooling liquid to increase the cabin temperature.

The heater core has two main functions:

Comfort: The heater core is the car heater. It is responsible for increasing the temperature in the passenger compartment (cabin) of the automobile and does so by taking the hot air generated by the engine together with the cooling system into the interior of the vehicle. This is crucial to maintaining a comfortable cabin temperature for vehicle occupants in winter months and cold weather.

Safety: The heater core also ensures driving safety during adverse conditions. One of the heater core’s functions of the heater is removing the ice and condensation from the vehicle’s windscreen and other windows. This improves visibility for the driver in cold weather and snowy conditions.
