Automotive A/C Condenser

This page explains how Automotive A/C Condenser is classified within Motor Vehicle Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.

Technical Definition & Core Assembly

An automotive A/C condenser is a heat exchanger that cools and condenses refrigerant gas from the compressor into liquid, releasing heat to the outside air.

Product Specifications

Technical details and manufacturing context for Automotive A/C Condenser

Definition
The condenser is a key component in a vehicle's air conditioning system, typically mounted in front of the radiator to receive maximum airflow. It is specified by vehicle model, dimensions, cooling capacity, and refrigerant type (e.g., R134a or R1234yf). Grades differ by core thickness, fin density, material quality (e.g., aluminum alloy), and corrosion resistance, with OEM and aftermarket variants. High-grade units feature brazed aluminum construction for durability and efficiency. The condenser operates by receiving hot, high-pressure refrigerant gas from the compressor. As the gas flows through serpentine tubes, heat is transferred to ambient air passing over the fins, causing the refrigerant to cool and condense into a liquid. The subcooled liquid then exits to the expansion valve or orifice tube. Typical parameters include core thickness of 16–32 mm, fin density of 12–20 fins/inch, tube width of 12–25 mm, tube thickness of 1.0–2.0 mm, heat transfer capacity of 5–15 kW, operating pressure of 1.5–3.0 MPa, burst pressure of ≥8 MPa, leakage rate of ≤5 g/year, corrosion resistance of ≥1000 hours per ASTM B117, temperature range of -40 to 120 °C, fin thickness of 0.1–0.2 mm, overall dimensions of 400–900 x 300–600 x 16–32 mm, dry weight of 2–5 kg, and compatibility with R134a and R1234yf refrigerants per SAE J639. Materials typically include aluminum alloy 3003 for tubes and fins, aluminum alloy 4045 for brazing clad, stainless steel for brackets and fittings, and rubber for seals and gaskets. Relevant standards include ISO 9001, SAE J639, GB/T 21361, and QC/T 657. Always verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
Hot, high-pressure refrigerant gas from the compressor enters the condenser's inlet. As it flows through the serpentine tubes, heat is transferred to the ambient air passing over the fins, causing the refrigerant to cool and condense into a liquid. The subcooled liquid then exits to the expansion valve or orifice tube.
