Cold Forging Heat Sink

The Cold Forging Heat Sink is an advanced thermal solution combining excellent mechanical strength and superior heat dissipation performance. Using the cold forging process, aluminum or copper materials are deformed under high pressure to create dense, precise fins that maximize surface area for efficient heat transfer. Compared with traditional extrusion or die casting, the cold-forged structure provides better thermal conductivity, durability, and uniform temperature distribution.

KINGKA Tech Industrial Limited, founded in 2010, is a professional manufacturer specializing in aluminum alloy thermal solutions. Our main products include Cold Forging Heat Sinks, Cold Plates, and Liquid Cold Plates, all designed to meet demanding thermal management requirements in electronics, automotive, telecom, and power industries.

Cold Forging Heat Sink

Key Features

  • High Thermal Conductivity: Cold forging creates a dense metal structure that enables superior heat transfer compared with standard extruded or cast heat sinks.

  • Material Flexibility: Available in aluminum cold plate, copper cold plate, or stainless-steel cold plate configurations depending on specific heat dissipation and mechanical requirements.

  • Custom Cold Plate Design: Supports liquid cold plate design, water-cooled cold plate, and cold plate cooling system for high-power components such as IGBTs, EV batteries, and power modules.

  • Precision Machining: Manufactured using CNC Machining, milling, and turning to achieve high precision and consistent flatness for direct mounting on heat-generating devices.

  • Reliable Performance: Stable thermal resistance and excellent long-term reliability, even under extreme environmental and electrical conditions.

  • Wide Compatibility: Designed for electronic cooling, industrial control, LED lighting, medical instruments, aerospace, automotive electronics, and telecom equipment.


Advantages

  1. Superior Cooling Efficiency:
    The forged fins provide a larger surface area and lower cold plate thermal resistance, ensuring optimal cold plate cooling performance.

  2. Enhanced Structural Integrity:
    Unlike die-cast or extruded heat sinks, the cold forging heat sink maintains grain structure continuity, improving strength and heat conduction.

  3. Lightweight Aluminum Alloy Design:
    Aluminum cold plates offer high heat transfer efficiency with reduced weight, ideal for EV battery cold plate and telecom cooling plate applications.

  4. Custom Engineering Support:
    KINGKA offers cold plate design for thermal management, integrating liquid cold plate cooling systems, tubed cold plates, and stacked fin heat sinks according to project requirements.

  5. Eco-Friendly and Durable:
    The cold forging process minimizes material waste and extends product life, supporting sustainable manufacturing practices.
