High Voltage Cold & Warm Integrated Bus Defroster
Product Introduction
Core Competitive Advantages
- All-season dual heating & cooling design
Eliminates the need for separate heating and cooling equipment, effectively cutting chassis installation space and overall procurement costs for bus manufacturers.
- High-performance PTC heating core
Boasts rapid warm-air output, self-limiting constant temperature control and over 95% thermal conversion efficiency, minimizing power drain to preserve vehicle battery range.
- Comprehensive multi-layer safety interlock system
Equipped with HVIL high-voltage interlock, over-temperature cutoff, over-current protection and fan linkage anti-dry-burn mechanism to rule out fire hazards during long-hour operation.
- Robust vehicle-grade construction
Thickened anti-corrosion metal housing with optimized heat dissipation structure, outstanding shock and vibration resistance to withstand bumpy road conditions and harsh cold/humid coastal environments.
- Full OEM & customizable service
Flexible customization on heating power, air outlet quantity and overall dimensions to perfectly match chassis layouts of diverse bus models.
Main Application Scenarios
Engineered for the full spectrum of new energy passenger vehicles ranging from 6m to 18m, including pure electric city transit buses, luxury tourist coaches, hybrid passenger vehicles and hydrogen fuel cell buses. It serves as an essential cabin climate control component, undertaking windshield defrosting, anti-fog treatment and driver compartment temperature regulation to satisfy all-weather operational demands for commercial passenger transport fleets.

◇The product has an attractive appearance. The surface should be free from scratches, damages, cracks, grease and other harmful deformations that affect usage and appearance. There
should be no defects such as scratches, burrs, rust, deformation or cracks. The outer surface should not have any sharp protrusions that could cause injury (such as sharp corners or sharp edges).◇When the defroster is in a stable working state, its surface temperature should not exceed 125℃, and the outlet air temperature should not exceed 65℃.
◇When the defroster is in a stable working state, the connection between the air ducts is well sealed without any air leakage. The insulation level of the high-voltage interface meets the
requirements of SAE J1742-2005 "Test Methods and General Performance Requirements for On-Vehicle High-Voltage Wire Connections" and GB/T-18384.3-2001 "Safety Requirements for
Electric Vehicles".
◇Condensate drainage: When the multi-functional defroster and demister assembly is tilted 15° forward/backward and 12° left/right relative to the vehicle's assembly position, in each air
outlet mode, the condensate water should be able to drain smoothly through the drain pipe, and no condensate water droplets should be blown out from any air outlet.
◇Operation safety capability: The electric defroster is equipped with a temperature switch. When the temperature of the PTC core reaches the set upper limit, the temperature switch will open , and the PTC core will stop working. When the temperature of the PTC core drops to the set lower limit, the temperature switch will close, and the PTC core will start working.
◇Sealing performance: When the inlet static pressure is 150Pa, the leakage of the housing (including the expansion valve, housing joint, etc.) and the air door should meet the following
requirements: housing leakage < 15L/s; leakage of a single air outlet < 1.0L/s.
◇Low-voltage steady-state current: 10.4A; high-voltage impulse current: 12.6A, impulse current duration: 0.3~0.5s; high-voltage steady-state current: 9.4A.
◇All crimping points of the low-voltage wiring harness included should be heat shrunk with heat shrink tubing containing hot melt adhesive (ensuring a tight and reliable seal after heat
shrinking). It is strictly prohibited to use tape for sealing.
◇Other requirements not specified herein shall be carried out in accordance with the "Design and Development Requirements for Heating, Cooling and Defrosting Devices (Systems)".
◇Unspecified dimensional tolerances shall be in accordance with GB/T1804-2000, grade v.
◇The items marked with ★ are special characteristics. The dimensions marked in the drawing do not include the thickness of the insulation layer.
