Must the car air conditioning evaporator be replaced if it leaks?

[Reyn]

It is not mandatory to replace a leaking car air conditioning evaporator. You should promptly visit a 4S shop for professional repair. If the leakage area is small, it can be patched; if the area is large, replacement is necessary. Otherwise, it may lead to severe consequences such as the air conditioning failing to cool and losing its working performance. Concept of the evaporator: The air conditioning evaporator is a type of evaporator. Its function is to utilize low-temperature liquid refrigerant, which easily evaporates under low pressure, transforming into vapor and absorbing heat from the cooled medium to achieve refrigeration. Principle: It relies on a fan to force air in the storage room to flow through the cooling coils inside the unit for heat exchange, thereby cooling the air and reducing the storage temperature. Among these, the refrigerant or coolant flows inside the coils, cooling the air outside the tubes through the tube walls, which is called a dry-type air cooler. When sprayed coolant liquid directly exchanges heat with the air, it is called a wet-type air cooler. A hybrid air cooler includes both cooling coils and a coolant spraying device. The commonly used dry-type air coolers in cold storage can be further divided into ceiling-mounted and floor-standing types based on their installation positions.
