Internal Components (Complete Assembly, One Unit)
Hydrophilic aluminum foil heat exchange fins + internally threaded copper tubing core
One-piece plastic evaporator housing, inlet and outlet copper pipe joints
Built-in expansion valve mounting position, sealing rubber ring
Cabion mounting bracket (original molded holes, direct installation without damage)
Material Advantages
Pipes: Internally threaded copper tubing, high heat exchange efficiency, vibration resistant, and less prone to refrigerant leakage
Fingers: Hydrophilic coated aluminum foil, prevents condensation buildup, corrosion resistant
Shell: High-strength flame-retardant engineering plastic, suitable for high and low temperature environments on construction sites
System Compatibility: Single-cooling air conditioner, compatible with R134a environmentally friendly refrigerant
IV. Functions and Roles
Installed inside the dashboard of the construction machinery cab, the core of the air conditioning system:
High-pressure liquid refrigerant flows through the expansion valve and enters the evaporator;
Absorbs heat from the air in the cab, the liquid refrigerant vaporizes and absorbs heat, blowing out cold air;
After heat exchange, the gaseous refrigerant returns to the compressor for recirculation;
Filters and reduces the air temperature in the cab, improving comfort during high-temperature construction site operations.
