Heat Sink Interface Component – Rubber and Plastic Product Manufacturing

Component Specifications

Definition

A precision-engineered component designed to facilitate efficient heat transfer from heat-generating elements to a heat sink within polycarbonate injection molded lens housings. It ensures optimal thermal management by providing a reliable mechanical and thermal connection between the heat source and cooling system.

Working Principle

Operates on thermal conduction principles, creating a low-thermal-resistance pathway between heat-generating components and the heat sink. The interface maximizes surface contact area and uses thermal interface materials to fill microscopic air gaps, enhancing heat transfer efficiency through conduction.

Materials

Aluminum 6061-T6 or copper C11000 with nickel plating for corrosion resistance; may include embedded thermal pads or phase-change materials

Technical Parameters

Surface Flatness ≤0.05 mm
Mounting Pressure 15-25 psi
Interface Thickness 0.5-3.0 mm
Thermal Conductivity ≥200 W/m·K
Operating Temperature -40°C to +150°C

Standards

ISO 22007, DIN 53436
