Description
ABB 1238HH24B-WDBABB
Technical Specifications:
- Size Specification: 120mm x 120mm x 38mm (1238 standard)
- Rated Voltage: 24V DC
- Fan Type: High-performance axial fan
Functional Features:
- High Airflow & Static Pressure: Effectively penetrates dense cooling fins to extract heat.
- Long-Life Bearings: Utilizes premium bearings to withstand continuous 24/7 operation.
- Low Noise Design: Optimized blade aerodynamics significantly reduce operational noise.
Application Scenarios:
- Forced air cooling inside variable frequency drives.
- Thermal management for industrial control cabinets.
- Heat dissipation for power supplies and rectifiers.
Performance Parameters:
- Rotational Speed: High-speed operation providing maximum cooling efficiency.
- Protection Rating: Adapted for dusty industrial environments.
Material Composition & Structural Features:
- Blade Material: High-strength engineering plastic with excellent dynamic balancing.
- Frame: Rigid metal or hard plastic frame with standard mounting holes.
Working Principle:
A motor drives the blades at high speeds to generate directional airflow, forcing convective heat exchange to expel internal equipment heat.
Installation Requirements:
- Observe the airflow direction indicator to ensure alignment with the equipment’s thermal design.
- Secure with matching screws to prevent vibration and acoustic noise.
Usage Precautions:
- Regularly clean dust from fan blades and protective grills.
- Replace the fan immediately if abnormal noise, vibration, or failure occurs.
