The function of the warm air water tank
The radiator is the core component of a car's heating system. Its main function is to convert the heat of the engine coolant into hot air, providing heating, defrosting and defogging, and regulating the temperature and humidity inside the vehicle to ensure driving comfort and safety in winter .
Core functions and working principles
The warm air water tank, as a heat exchanger, achieves the following functions through the circulation of coolant:
Youdaoplaceholder0 Interior heating : The engine coolant flows through the metal pipes of the warm air radiator, and the heat is transferred to the radiator fins. The blower heats the air and then delivers it to the driver's cabin. The exhaust air temperature can reach 40-60℃, and it supports multiple Settings for adjustment.
Youdaoplaceholder0 defrosting and fogging : Quickly remove frost and fog from the front windshield and rearview mirrors through dedicated air outlets. Within 2-3 minutes, 75% of the area covered with frost can be cleared, ensuring a clear driving view.
Youdaoplaceholder0 Temperature and humidity regulation : In conjunction with the air conditioning system, it achieves zonal temperature control (accuracy ±3℃). When integrated with a humidity sensor, it can automatically maintain a relative humidity of 50-60%, enhancing comfort.
The working principle is as follows: The high-temperature coolant from the engine flows into the internal pipes of the warm air radiator. The heat is transferred to the external air through the metal surface. The fan blows the heated air into the vehicle, forming a heating cycle.
Maintenance and fault prevention
The warm air water tank needs regular maintenance to avoid common malfunctions
Youdaoplaceholder0 blockage : Caused by poor-quality coolant or long-term failure to replace it, it is manifested as the warm air not being warm. The coolant needs to be replaced and the radiator cleaned every 2-3 years.
Youdaoplaceholder0 leakage : It is mostly caused by aging or corrosion of the coolant. It is necessary to check the coolant level and the sealing of the pipeline, and replenish or replace it in time.
Maintenance suggestions include using high-quality coolant, regularly cleaning the dirt on the water tank surface, and monitoring the water temperature to prevent overheating and affecting the lifespan.
A malfunction of the warm air radiator can lead to the failure of the warm air function, coolant leakage causing engine overheating, deterioration of the interior environment and driving safety hazards . It is necessary to carry out timely maintenance to avoid serious damage to the engine.
The main impacts and symptoms
Youdaoplaceholder0 warm air function failure : When blocked or cracked, the coolant circulation is hindered, and the air conditioning outlet cannot output hot air, making driving and riding cold in winter.
Youdaoplaceholder0 Engine performance risk : coolant leakage can cause the engine to lack water and overheat, which may lead to burnout. Blockage affects the operation of the water pump, causing unstable power.
Youdaoplaceholder0 Interior environment and safety : Leakage causes continuous fogging and unpleasant odors on the front windshield. In severe cases, antifreeze flows into the vehicle. Obstructed visibility and reduced braking performance increase the risk of accidents.
Typical symptoms of : the warm air is not warm enough, the coolant is consumed rapidly, there is leakage from the chassis, the engine has a high-temperature alarm, and there is an unpleasant smell inside the vehicle.
The best method for cleaning clogged warm air water tanks should be selected based on the degree of clogging and the characteristics of the vehicle model. The following is a comprehensive recommended plan:
High-pressure air gun + chemical cleaning agent combined method (Recommended for priority trial)
Youdaoplaceholder0 Disassemble the inlet and outlet water pipes : Use a carp pliers to loosen the clips and disconnect the warm air water tank from the pipeline
Youdaoplaceholder0 high-pressure air gun unblocking : Insert the air pump nozzle into the water inlet pipe, and the high-pressure air flow will blow in the opposite direction to remove the internal debris and silt
Youdaoplaceholder0 Chemical immersion cleaning : Add a special descaling agent mixed with clean water, and idle for 30 minutes to allow the agent to circulate and dissolve the scale
Youdaoplaceholder0 Multiple water changes and rinsing : Use high-pressure gas to assist in draining, repeat three times until clear water flows out, and finally add new antifreeze
Disassembly deep cleaning method (applicable to severe blockages)
The dashboard and other components need to be disassembled to fully expose the heater tank. Use professional tools to thoroughly remove stubborn dirt
Note that the operation should be carried out by professionals to avoid damaging the surrounding components
Preventive maintenance suggestions
Change high-quality antifreeze every year and avoid using hard water
When cleaning the cooling system, simultaneously inspect the piping of the warm water tank
If it is found that the temperature of the warm air outlet is uneven (one heat pipe and one cool pipe), it should be dealt with promptly
Youdaoplaceholder0 notes :
Chemical cleaning agents should be selected that are compatible with the material of the water tank to avoid corrosion
Make sure the engine is turned off and the cooling system cools down before operation to prevent scalding
For older models, it is recommended to give priority to the non-disassembly cleaning method to reduce maintenance risks
