In cold weather, a car heater can indeed quickly increase the temperature in a car to a certain extent.
First of all, the working principle of a car heater is to use the heat generated by the engine. When the engine is started and runs for a period of time, the coolant is heated and flows through the radiator. The car heater sends the hot air emitted by the radiator into the car through the air duct, thereby increasing the temperature in the car. Some vehicles are also equipped with seat heating and steering wheel heating functions. These auxiliary heating devices can directly provide warmth for the driver and passengers, further accelerating the increase in the warmth in the car.
To make the car heater quickly increase the temperature in the car, the correct operation method is also required. After starting the engine, let the engine preheat for 2-3 minutes, wait for the oil to circulate fully, and then wait for the engine temperature to rise to the normal operating temperature. It usually takes 8-15 minutes to run before turning on the warm air. Set the air conditioning system to the internal circulation mode, and adjust the air outlet mode to the soles of the feet and the front window glass area, so as to prevent the cold air outside the car from entering and concentrate the heating output to the areas where the human body needs it most.
Different types of car heaters also have different speeds of increasing the temperature. The heater of a traditional fuel vehicle relies on the heat of the engine. After the engine reaches the normal operating temperature, it can quickly raise the temperature inside the vehicle. Some heaters of new energy vehicles use electric heating, which has a relatively more direct heating speed, but may be limited by the battery power and power. Some high-end models are equipped with more advanced heating technology and control systems, which can use energy more efficiently and achieve faster heating speed.
