What are Extruded Cold Plates?

Extruded Cold Plates (ECPs) are liquid-cooled heat sinks manufactured using a metal extrusion process. This process involves extruding a heated metal billet (usually aluminum alloy) through a die with a specific cross-sectional shape, forming the cold plate's outer contours and the coolant channels within in the same process.
This one-piece manufacturing method gives the extruded cold plate excellent structural integrity, eliminating the need for welding or brazing, thereby reducing potential leak points. Extruded cold plates are ideal for providing cost-effective and mass-produced solutions for medium heat load applications and are widely used in fields with high requirements for cost-effectiveness and mass production efficiency.
 
Additional notes on extruded cold plates
Channel Design: The channel design of extruded cold plates is relatively simple and is generally suitable for straight channels or channels with simple bends, which is limited by the complexity of the extrusion die. For extremely complex microchannels or multi-layer flow channels, brazed cold plates or FSW cold plates may be more suitable.
Surface treatment: Cold plates can undergo a variety of surface treatments, such as anodizing (to increase corrosion resistance and insulation), passivation, chemical nickel plating, etc., to meet the needs of different application environments.
Length Limitation: The length of extruded cold sheets is often limited by the length of the extrusion equipment and transportation conditions. Winshare can provide customized services of different lengths according to your specific needs.

What are the advantages of Extruded Cold Plates?

Extremely cost-effective

Integrated extrusion molding eliminates the need for complex welding and is particularly suitable for mass production, significantly reducing unit costs.

Excellent structural integrity

The weld-free design reduces potential leak points and provides higher reliability and structural strength.

Good thermal performance

For medium heat load applications, it provides stable and efficient heat dissipation capabilities to ensure normal operation of the equipment.

Design flexibility

The shape and size of the flow channel can be customized within a certain range to meet the heat dissipation requirements of different components.

Lightweight advantages

Manufactured primarily from aluminum alloy, it has inherent lightweight properties that help reduce overall system weight.

High production efficiency

The extrusion process is highly efficient, enabling rapid, large-scale production and shortening lead times.

The main difference between Extruded Cold Plate and other cold plates

Extruded cold plates have a unique manufacturing method and performance characteristics, occupying a place in liquid cooling solutions. They have different focuses from other cold plate types
Bonded-fin-heat-sink4_03
Manufacturing process
Extruded cold plate: Molded in one piece through an extrusion die, with no welds and no connection interfaces.
Embedded Tube Cold Plates: Cooling tubes are pressed or bonded into the base plate slots.
Brazed cold plate: Multiple metal sheets are fused together through high-temperature brazing to form a complex internal structure.
FSW Cold Plate: Solid-state connection using friction stir welding, high weld quality, no melting
 
Flow channel complexity
Extruded cold plate: The flow channel design is relatively simple, usually a straight line or a simple curved channel, which is limited by the complexity of the extrusion die.
Embedded tube cold plate: The flow channel is tubular, which allows a certain degree of layout flexibility.
Brazed Cold Plates / FSW Cold Plates: Extremely complex and high-density internal fin or microchannel structures can be designed for optimal heat transfer.
Bonded-fin-heat-sink4_03
Thermal performance range
Extruded Cold Plates: Suitable for medium heat load applications, providing good heat dissipation performance.
Embedded tube cold plate: Suitable for low to medium heat loads.
Brazed Cold Plates/FSW Cold Plates: Designed to handle extremely high heat flux and high power cooling needs.
 
Cost and applicable batch
Extruded cold plate: High production efficiency, extremely low unit cost after mold cost is amortized, most suitable for mass production.
Embedded tube cold plates: Cost-effective for medium batch sizes.
Brazed cold plate/FSW cold plate: The manufacturing process is complex and the cost is relatively high. It is suitable for high performance, small batch or medium batch customization needs.

What material combinations are supported for Extruded Cold Plates?

The extrusion process has certain limitations in the choice of metal materials, but it demonstrates excellent performance and cost-effectiveness in certain materials. Winshare Thermal Alloy's Extruded Cold Plates are primarily made of the following materials
image 1089
Aluminum alloy Extruded cold plate
Aluminum alloys are the most commonly used materials for extruded cold plates, particularly grades like 6061 and 6063. These alloys offer excellent thermal conductivity, lightweight construction, good machinability, and corrosion resistance. The extrusion process maximizes these advantages, making them ideal for cooling moderate heat loads in applications such as consumer electronics, LED lighting, and telecommunications equipment.
 
Other material potentials
Although aluminum alloy is the mainstream, in theory other extrudable metals such as copper can also be used to manufacture extruded cold plates, but this usually increases the cost and manufacturing difficulty, and is not as common as aluminum alloy in actual applications.
Our team of engineers will recommend the most suitable aluminum alloy grade and flow channel design based on your specific application needs and budget, ensuring the cold plate achieves the best balance between performance and cost-effectiveness.

How cost-effective are Extruded Cold Plates?

Extruded Cold Plates offer excellent cost-effectiveness in high-volume production, making them ideal for many moderate heat load applications. This cost advantage stems primarily from their unique manufacturing process
 
Winshare Thermal Alloy, with its advanced extrusion technology and optimized management, can provide you with highly competitive Extruded Cold Plates solutions, ensuring you achieve the best balance between performance and budget.
  Low unit manufacturing cost
Extrusion molding is an efficient continuous production process. Once the mold is developed, subsequent production is fast and highly automated, significantly reducing the direct manufacturing cost of each cold plate.
 
  Reduce subsequent processing
Because the runner is integrally formed during the extrusion process, the need for complex welding, brazing or internal machining is reduced, saving significant labor and equipment costs.
 
  High material utilization rate
Extrusion processes typically result in higher material utilization and less scrap, further reducing overall material costs.
 
  Long-term savings from reliability
The weld-free, one-piece structure means lower risk of leakage and higher reliability, reducing long-term costs of product failure and maintenance.
 
  Fast time to market
Efficient production processes mean shorter delivery cycles, helping to bring products to market faster and seize business opportunities.
