Product Description

IP67 Waterproof DC Cooling Fan (24V) for 24kW Bus Heat Pump HVAC Systems

Overview

The IP67-rated waterproof DC cooling fan (Model: DV24V) is a high-performance, ruggedized airflow solution engineered specifically for 24kW bus heat pump air conditioning systems. Designed to operate reliably in harsh outdoor and under-hood environments, this 24V DC fan ensures consistent thermal management of condensers, evaporators, power electronics, and battery cooling modules—critical for maintaining system efficiency and passenger comfort in electric and hybrid city buses.

With an IP67 ingress protection rating, the DV24V fan is fully dust-tight and capable of withstanding temporary immersion in water up to 1 meter for 30 minutes, making it ideal for transit applications exposed to rain, snow, road spray, and frequent washdowns. Its robust construction meets automotive-grade durability standards while delivering quiet, energy-efficient operation over extended duty cycles.

Key Features & Benefits

IP67 Waterproof & Dustproof: Sealed motor housing and protected electrical connectors prevent contamination from moisture, dust, and conductive debris.
24V DC Automotive Compatibility: Optimized for standard commercial vehicle electrical systems; supports PWM or 0-5V speed control via CAN or LIN interfaces.
High Static Pressure & Airflow: Specially designed impeller and shroud generate strong airflow even against dense heat exchanger fins—essential for compact bus HVAC units.
Long Service Life: Dual-ball bearing or sealed sleeve bearing options rated for >30,000 hours at 50°C ambient temperature.
Low Electromagnetic Interference (EMI): Compliant with CISPR 25 Class 3 and ISO 11452 standards for electromagnetic compatibility in sensitive vehicle electronics environments.
Reverse Polarity & Overload Protection: Integrated circuit safeguards prevent damage from wiring errors or voltage spikes.

Life Expectancy	≥ 30,000 hours @ 50°C

Note: Actual airflow and power vary by frame size (e.g., 172mm, 223mm, or custom diameters).

Applications in Bus Heat Pump Systems

In a 24kW bus heat pump HVAC unit, the DV24V fan typically serves in the following roles:

Condenser Fan: Drives ambient air through the outdoor heat exchanger during cooling or heat recovery mode.
Evaporator Blower (Auxiliary): Supports defrost cycles or secondary cabin airflow loops.
Power Electronics Cooling: Cools inverters, DC-DC converters, or motor controllers integrated with the thermal system.
Battery Thermal Management: Provides forced convection for liquid-cooled battery chiller units.

According to SAE J1211 and ISO 16750-4 standards for environmental testing of road vehicle components, IP67-rated fans are essential for ensuring uninterrupted operation in public transport fleets operating in coastal, snowy, or high-humidity regions. Industry data from manufacturers like ebm-papst, Delta Electronics, and NMB Technologies confirms that IP67 BLDC fans reduce field failure rates by over 60% compared to IP54-class units in heavy-duty mobile applications.

Reliability & Integration

The DV24V fan undergoes rigorous validation including:

Thermal shock cycling (-40°C ↔ +85°C)
Salt spray testing (ASTM B117, 500+ hours)
Vibration endurance (SAE J1211, 10-500 Hz, 5g RMS)

Its modular design allows easy integration into existing HVAC housings, with optional features such as tachometer output, stall detection, and soft-start functionality to support predictive maintenance strategies in smart e-bus fleets.

For OEM customization—including frame dimensions, blade profile, connector type, or communication protocol (e.g., CANopen)—our engineering team provides rapid prototyping and compliance support aligned with global automotive safety and environmental regulations.
