32x11x20 H-style Aluminium Heat sink

A 32x11x20 H-style Aluminium Heat Sink is a compact thermal management component designed to dissipate heat from electronic devices such as power transistors, voltage regulators, or small integrated circuits.

🔧 Physical Specifications

• Dimensions:

  • Length: 32 mm

  • Width: 11 mm

  • Height: 20 mm

• Style: H-style

  • This typically refers to the profile or shape of the heatsink, resembling the letter “H” when viewed from the side. It usually has two vertical walls connected by a central base, forming air channels in between to enhance airflow.

🧊 Thermal Characteristics

• Material: Aluminium

  • Lightweight and has good thermal conductivity (~200 W/m·K), making it ideal for passive cooling.

• Cooling Method: Passive air cooling

  • Relies on natural convection (no fan needed), suitable for low to moderate power dissipation.

• Surface Area: Designed with fins or extended surfaces to increase heat dissipation efficiency.

⚙️ Application

• Suitable for:

  • TO-220 or TO-3P packages

  • Low to medium-power transistors, regulators, diodes, etc.

  • DIY electronics, power supply circuits, amplifier modules

🧩 Mounting & Compatibility

• May include mounting holes for:

  • Screwing down the device directly

  • Attaching to a PCB or chassis

• Often compatible with thermal paste or thermal pads to improve heat transfer between the component and the heatsink.
