Component Specifications

Definition
A precision-engineered enclosure designed to house and protect the evaporator fan motor in refrigeration systems. It provides thermal insulation to prevent condensation, structural support for motor mounting, and airflow management for efficient heat dissipation while maintaining electrical safety standards.
Working Principle
Acts as a protective barrier that isolates the motor from moisture and contaminants while facilitating controlled airflow for cooling. The housing's geometry directs air across the motor windings and bearings, preventing overheating and ensuring consistent fan operation in humid, low-temperature environments.
Materials
Typically injection-molded from flame-retardant ABS (UL94 V-0 rated) or polypropylene with 20-30% glass fiber reinforcement for dimensional stability. May include rubber gaskets (EPDM) for sealing and stainless steel mounting brackets.
Technical Parameters
  • Weight 150-300g
  • IP Rating IP44 minimum
  • Dimensions Varies by motor size (common: 120x80x60mm)
  • Wall Thickness 2.5-3.5mm
  • Flammability Rating UL94 V-0
  • Operating Temperature -30°C to +70°C
Standards
ISO 9001, IEC 60335-2-24, UL 507
