Custom Heat Sinks & Machining

Engineering Thermal Solutions That Power Your Critical Systems

What is a Heat Sink? Why Customize It?

A heatsink is a passive heat exchanger designed to dissipate thermal energy from a device or component by increasing the surface area in contact with the surrounding air, effectively transferring heat away from critical electronic or mechanical systems.

A tailored heat sink can optimize thermal performance by precisely matching fin geometry, material selection, and surface characteristics to the exact heat generation profile of a specific device, ensuring more efficient heat dissipation, improved component reliability, reduced operating temperatures, and potentially extending the lifespan of the equipment.

Types of Custom Heat Sinks

Unlike off-the-shelf “one-size-fits-all” solutions, Richconn’s custom heat sink solutions are designed to maximize thermal conductivity efficiency, reduce weight and size, and seamlessly integrate with the specific design and installation requirements of the target application.

Flat/Straight Fin Heat Sinks

have straight, parallel fins extending vertically from a flat base

Pin Fin Heat Sinks

Composed of multiple cylindrical or rectangular pins extending from a base

Skived Fin Heat Sinks

Created by precisely cutting and bending metal from a solid base

Folded/Fluted Fin Heat Sinks

Fins are created through folding or complex geometric shaping

Circular Fin Heat Sinks

Fins are arranged in a circular pattern radiating from a central point

FAQs About Custom Heat Sinks

We typically need detailed specifications such as dimensions, mounting configurations, required cooling capacity (BTU or kW), flow rates, operating temperature and pressure, fluid type, and any special materials or coatings. If you have existing drawings, performance requirements, or technical standards, please share them as well.

Absolutely. We’ll start by reviewing your basic performance targets—such as heat dissipation, system pressure, flow rates, and space constraints—and then propose an optimal configuration.

Our manufacturing methods include extrusion, CNC machining, skiving, and bonded fin construction.

Aluminum and copper are commonly used; aluminum is cost-effective and lightweight, while copper offers higher thermal conductivity for more demanding applications.

You’ll have a dedicated project manager who will provide regular updates, ensure timely responses to inquiries, and offer status reports at key milestones, from initial design approval through final delivery.

We can customize nearly every aspect, including fin configurations, tube types, core densities, mounting brackets, fittings, and inlet/outlet orientations. We also offer custom surface treatments, branding elements, integrated sensors, and advanced coating options.
