Custom Heatsink Large Round Extruded Aluminum Profiles Industrial Sunflower Profile Radiator Cooler Aluminum Led Heat Sink

Overview of Heatlinks

Heatlinks function by providing a path of low thermal resistance between a heat source (such as an electronic component) and a heat sink or cooling system. They can be particularly useful in environments where space constraints limit the use of traditional cooling methods, or when a passive thermal management solution is preferred.

Heatlinks can operate based on different principles, including phase change materials, solid-state conduction, or even fluid-based systems. The choice of technology depends on the application’s specific requirements, such as operating temperature range, power dissipation levels, and spatial limitations.

Features of Heatlinks

High Thermal Conductivity: Designed to offer high thermal conductivity, ensuring efficient heat transfer from the source to the sink.

Compact Design: Often compact, allowing them to fit into tight spaces within electronic assemblies or other equipment.

Passive Operation: Typically do not require external power to function, relying instead on the natural flow of heat from hot to cold areas.

Durability and Reliability: Manufactured to withstand repeated thermal cycles and harsh environmental conditions without degradation of performance.

Low Profile: Thin profiles help minimize the impact on the overall design of products.

Versatility: Can be tailored to fit various applications, from consumer electronics to industrial machinery and aerospace components.

Customizable: Available in different shapes, sizes, and configurations to meet specific design needs.

Cost-Effective: Provide an economical solution for thermal management compared to more complex cooling systems.

Minimal Maintenance: Generally require little to no maintenance once installed.

Environmental Compatibility: Designed to be compatible with a wide range of environments, including those that may contain corrosive elements or experience significant temperature fluctuations.

Specifications of Custom Heatsink Large Round Extruded Aluminum Profiles Industrial Sunflower Profile Radiator Cooler Aluminum Led Heat Sink

Here’s the product description for the custom heatsink:

This is a large round extruded aluminum profile heatsink. It is custom-made. Manufacturers build it specifically for your requirements. The shape is circular. It fits applications needing a big, rounded cooling solution. The design resembles a sunflower. This pattern maximizes surface area. More surface area means better heat dissipation. Heat moves away from hot components faster.

The material is pure aluminum. Aluminum conducts heat efficiently. Extrusion creates the profile. This process ensures precise dimensions and consistent quality. The heatsink handles high thermal loads. It is ideal for demanding industrial settings. Power electronics, motor drives, and heavy machinery often use this type. It also works perfectly for powerful LED lighting systems. LEDs generate significant heat. This cooler keeps them running reliably and extends their life.

You can order different sizes. The diameter and height are customizable. Fin thickness and spacing adjust to your thermal needs. Maximum diameter typically reaches 200mm. Heights can go up to 150mm. Fin height usually stays under 50mm. Base thickness ranges from 10mm to 30mm. This ensures structural strength and good heat transfer from the source. Surface finishing options exist. Anodizing is common. It protects against corrosion and can be black. Polishing gives a shiny look. Natural mill finish is also available.

The heatsink performs well. Its thermal resistance is low. It can manage power densities above 300W. The design promotes natural airflow convection. Sometimes forced air cooling helps further. This cooler operates reliably across a wide temperature range.

Applications of Custom Heatsink Large Round Extruded Aluminum Profiles Industrial Sunflower Profile Radiator Cooler Aluminum Led Heat Sink

Large round extruded aluminum heatsink profiles solve tough cooling problems. These custom heatsinks handle high heat loads. Their big round shape offers lots of surface area. This surface area lets heat escape fast into the air. Air moves easily around the smooth curves. This design cools things better than flat shapes.

Industrial machines get very hot inside. Motors, drives, and controllers need reliable cooling. Large round extruded heatsinks attach directly. They pull heat away from critical parts. This prevents overheating. It keeps machines running longer. Factories use these heatsinks daily.

Power electronics generate significant heat. Things like power supplies and inverters need strong cooling. The round profile fits snugly around components. Heat transfers quickly into the aluminum. Fans or natural airflow take the heat away. This protects sensitive electronics from damage.

LED lighting gets hot, especially bright lights. Heat shortens LED life and dims the light. The sunflower profile design is common here. Its many fins spread out like petals. This maximizes cooling surface in tight spaces. Aluminum conducts heat perfectly for LED arrays. It keeps light output strong for years.

Solar power systems use big converters. These converters turn DC power from panels into usable AC power. They work hard under the sun. Heat builds up fast. Custom round extruded heatsinks mount onto these units. They provide dependable cooling outdoors. This ensures steady power production.

Automotive electronics face harsh conditions. Engine compartments are hot and cramped. Electric vehicle systems need efficient cooling. Large round extruded heatsinks fit complex shapes. They manage heat from batteries, chargers, and controllers. This keeps vehicles safe and reliable.

The aluminum material is key. It absorbs heat rapidly. It spreads heat evenly across the whole profile. Extrusion allows any needed length. Custom shapes fit specific devices perfectly. This custom fit gives the best cooling performance.

5 FAQs of Custom Heatsink Large Round Extruded Aluminum Profiles Industrial Sunflower Profile Radiator Cooler Aluminum Led Heat Sink

What material are these heatsinks?
They are made from extruded aluminum. Aluminum moves heat away fast. This keeps things cool efficiently. It is also strong and lasts a long time.

How do these heatsinks cool things?
The large round shape offers a big surface area. Heat moves from the hot device into the aluminum base. Then the heat spreads into the fins. Air flows over the fins. This carries the heat away. The sunflower fin pattern helps air move better.

Can you make custom sizes and shapes?
Yes. We specialize in custom heatsinks. We extrude aluminum to your exact needs. You tell us the diameter, height, fin count, and base thickness. We make it fit your device perfectly. This ensures the best cooling.

Why use a sunflower fin pattern?
The sunflower design has fins radiating from the center like petals. This pattern creates more surface area close to the heat source. More surface area means faster heat transfer. Air moves smoothly through the gaps. This boosts cooling performance significantly.

Where are these large round heatsinks used?
They are common in big LED lights needing serious cooling. Think streetlights, stadium lights, and high-power industrial lamps. They also cool power electronics, motor drives, and other industrial equipment generating substantial heat. The large size handles high thermal loads.
