New Energy Power engine parts PTC heater Warm air core 8101115-C1B00

Built as the core heat exchange component of the PTC heating system, this warm air core features a multi-channel aluminum microchannel structure optimized via CFD simulation. It integrates 120+ microchannels (1.2mm diameter) and a corrugated aluminum fin design, achieving a heat exchange area of 1.8㎡—30% larger than traditional copper tube cores. The core converts 96% of PTC heater energy into usable heat, raising the cab temperature from -20℃ to 20℃ in 6 minutes, 25% faster than conventional warm air cores. Its low air resistance design (≤50Pa) reduces the load of the HVAC blower, cutting overall heating system energy consumption by 15% and extending the vehicle’s winter driving range by 8-10%

Safety is prioritized with multiple protective designs tailored for new energy vehicle scenarios. The core’s aluminum alloy substrate (6063-T5) has excellent insulation performance, with a volume resistivity of ≥10¹² Ω·cm, ensuring electrical isolation between the high-voltage PTC heater and the low-voltage HVAC system. A built-in temperature fuse cuts off heat transfer when the core surface exceeds 85℃, preventing overheating and fire risks. The coolant channels use a one-piece stamping process with no welding seams, eliminating leakage risks (tested to withstand 1.5MPa pressure for 30 minutes with no drop). Additionally, the core is flame-retardant (UL94 V-0 rating), complying with ISO 6469-3 electric vehicle safety standards

Engineered to endure the harsh operating environments of new energy vehicles, the warm air core exhibits exceptional corrosion and frost resistance. The aluminum microchannels undergo a three-layer anti-corrosion treatment: chemical conversion coating, electrophoretic coating, and hydrophobic coating—resisting corrosion from ethylene glycol coolant and deionized water for ≥8 years. The core’s structure avoids dead volume, preventing coolant stagnation and frost cracking in low temperatures (-40℃). It undergoes 500 freeze-thaw cycles (from -40℃ to 80℃) without structural damage, adapting to frigid northern winters. The surface fin structure is designed to resist dust accumulation, reducing maintenance frequency by 40%

The warm air core is designed for hassle-free installation and low maintenance, ideal for fleet operations and after-sales service. Its compact structure and standardized mounting brackets align perfectly with the original HVAC assembly’s slots, requiring only 4 M6 bolts for fixation—two technicians can complete replacement in 30 minutes, 50% faster than non-OE cores. The core’s smooth internal channels minimize scale formation, eliminating the need for regular chemical cleaning. It comes with pre-installed rubber seals on the coolant interfaces, ensuring a leak-proof connection without additional gaskets. Backed by a 2-year/200,000km warranty, it reduces downtime and maintenance costs for new energy vehicle operators, ensuring reliable heating performance in all seasons
