5A-1301010E is the OEM evaporator assembly for BYD E2 (also known as AC cooling core). Constructed from high‑grade aluminum alloy with precision fin‑and‑tube design, it delivers high heat exchange efficiency, excellent pressure resistance and corrosion resistance. Manufactured to original factory specifications with exact mounting points and pipe connections, it supports direct installation without modification. As the core cooling component, it absorbs cabin heat, cools and dehumidifies airflow for consistent, efficient AC performance. Each unit undergoes strict leakage and pressure tests to ensure reliability. Ideal replacement for leaking, damaged or inefficient evaporators.
