Thermal Sink / Housing Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

A thermal sink/housing is a critical component in emitter modules designed to efficiently dissipate heat generated by electronic or optical elements while providing structural protection and electromagnetic shielding. It combines heat transfer functionality with mechanical housing capabilities to maintain optimal operating temperatures and ensure device reliability.

Working Principle

Operates on conduction and convection principles: heat transfers from the emitter to the sink via direct contact, then dissipates to the environment through surface area exposure and airflow, while the housing provides physical protection and thermal insulation.

Materials

Aluminum alloys (e.g., 6061, 6063) for lightweight conductivity; copper for high thermal performance; thermal interface materials (TIMs) like silicone pads or thermal paste; anodized or powder-coated finishes for corrosion resistance.

Technical Parameters

Weight 50-500g
Dimensions Customizable per module requirements
Mounting Type Screw or clip-based
Surface Finish Anodized or coated
Thermal Conductivity 150-400 W/m·K

Standards

ISO 9001, DIN EN 14024
