Company Overview

Cooling Source is a U.S.-based designer and manufacturer of high-performance thermal management solutions serving defense, aerospace, medical, telecommunications, EV, and industrial markets.

We specialize in the engineering, qualification, and production of precision heatsinks and thermal assemblies where reliability, repeatability, and compliance are non-negotiable. Our approach is grounded in disciplined engineering, vertically integrated manufacturing, and full lifecycle control—from initial thermal modeling through production and long-term program support.

Because we own and operate our manufacturing facilities, Cooling Source maintains direct control over process integrity, quality systems, lead times, and intellectual property, enabling us to meet the strict requirements of regulated and mission-critical applications.

Engineering & Thermal Design

Cooling Source operates as an engineering partner, not simply a component supplier.

We support customers beginning with thermal simulation, heat load analysis, and mechanical integration, ensuring that each design is optimized for both performance and manufacturability. Designs are evaluated for thermal resistance, airflow behavior, material selection, structural integrity, and long-term reliability under real-world operating conditions.

Our engineering workflow enables rapid iteration through prototype validation and smooth transition into production, minimizing technical risk and reducing total program cost.

Manufacturing Capabilities

Our manufacturing operations are designed to support low-volume, high-mix programs as well as scalable production for long-term contracts.

Cooling Source offers a broad range of precision thermal manufacturing technologies, including:

• High-efficiency fin architectures optimized for maximum heat transfer
• Precision CNC machining
• Value-added assembly and secondary operations
• Rapid prototyping with production-intent processes

All manufacturing processes are tightly controlled to ensure dimensional accuracy, thermal consistency, and repeatability across production runs.

Cooling Source is ISO 9001:2015 certified, with products fully RoHS compliant, and strict adherence to EICC conflict-free smelter programs. Our systems and processes are structured to support ITAR-sensitive programs, controlled documentation, and customer-specific compliance requirements.

Quality & Process Control

Quality at Cooling Source is systemic—not inspected in after the fact.

All personnel are thoroughly trained and certified prior to working on customer programs. Our stable workforce, low turnover, and disciplined operating culture ensure consistency across every stage of production.

We employ structured quality planning, in-process controls, and final inspection protocols designed to meet the expectations of defense, aerospace, and medical OEMs. These systems support traceability, documentation control, and continuous improvement throughout the product lifecycle.

Supply Chain & Program Control

Cooling Source provides end-to-end program ownership.

From initial design through sustained production, we manage materials, processes, and suppliers to ensure schedule integrity and cost control. Vertical integration allows us to respond quickly to engineering changes while maintaining compliance and quality standards.

Our customers benefit from single-source accountability, reduced supply chain risk, and predictable execution—even in demanding or regulated environments.

Customer Support & Long-Term Partnership

We view customer support as an extension of our engineering responsibility.

Cooling Source provides responsive, technically knowledgeable support throughout the life of the program, including post-production assistance, design refinements, and ongoing performance optimization. Our global reach is matched by localized expertise, ensuring effective support wherever our customers operate.

We are committed to long-term partnerships built on technical credibility, manufacturing discipline, and trust.

A Personal Commitment

Thank you for considering Cooling Source as your thermal management partner.

I personally stand behind our commitment to engineering rigor, manufacturing excellence, and uncompromising quality. We will work diligently to meet your technical, regulatory, and performance requirements—without exception.

We look forward to supporting your most demanding applications.
