B2-02
TCHAIN
L020200057
The B2-02 evaporator coil assembly is a dedicated indoor heat exchange component designed for TCH07IZA-R rooftop air conditioning units, widely installed on 7-meter mini city buses, campus shuttle buses and short-distance tourist coaches. As the cooling core inside the passenger compartment, it absorbs heat from cabin air to realize refrigeration, directly determining the cooling speed and comfort of the whole bus air conditioner.
Blue Hydrophilic Anti-Frost Fins
Equipped with blue hydrophilic coated aluminum fins, which speed up condensate drainage, avoid water accumulation and thick frost layer under low-temperature operation. It keeps stable heat absorption efficiency and effectively prevents water dripping into the passenger cabin.
Thickened Seamless Copper Tube Heat Exchange Structure
Adopts thick seamless copper tubes with precision tube-expanding process to form tight fit with fins, maximizing heat exchange area. Strong thermal conductivity enables fast cabin temperature drop, ideal for high-temperature tropical working environments.
Double-Row Split Core Layout
Dual-layer coil design enlarges heat exchange capacity while controlling overall size to perfectly fit the compact internal space of TCH07 small bus AC units. Reinforced pipeline bending and welding resist vibration during vehicle driving.
100% High-Pressure Air Tightness Inspection
Each finished evaporator core undergoes strict nitrogen pressure leakage test before delivery, eliminating refrigerant leakage failure caused by bumpy roads, cutting fleet after-sales maintenance frequency and cost.
Original Size Direct Replacement
All mounting hole positions, pipeline interface dimensions fully consistent with original TCH07IZA-R specifications, no cutting or modification required during installation, greatly shortening on-site overhaul working hours.
