6061 6063 aluminum extrusion anodized black heat sink

custom 6061 6063 Aluminum Extrusion anodized black heat sink,Technical:Extrusion aluminum,could custom to CNC work.

Custom according to heat sink samples or drawings.Welcome to send us your drawings or samples for quoation~

We manufacturer custom specific heat sinks based on drawings in small and large batches.The end product uses of the heat sinks we manufacturer include:led spotlights,led track lights,led down lights,led street lights,led stage lights,led tunnel lights,etc.All endless array of options means you can choose the material(including aluminum or bronze),as well as the finish(including anodizing,plating,electroplate,and powder coating).A heat sink is a component that increases the heat flow away from a hot device.It accomplishes this task by increasing the device's working surface area and the amount of low-temperature fluid that moves across its enlarged surface area.Customizing heat sinks meet the thermal application requirements.Customizing heat sink helps reduce a heat sink cost,and heat sink helps reduce a heat sink cost,and also can reduce the prototype time dramatically.

What is a heat sink?A heat sink is a component that increases the heat flow away from a hot device.It accomplishes this task by increasing the device’s working surface area and the amount of low-temperature fluid that moves across its enlarged surface area.Based on each device’s configuration,we find a multitude of heat sink aesthetics,design,and ultimate capabilities .You can see a straight fin heat sink in the image at the top of this article and a flared fin heat sink in the image blow.Each heat sink is valuable in applications that may have varying.

How does a heat sink work?A heat sink works by moving heat away from a critical component.Nearly all heat sinks accomplish task in four basic steps:1. The source generates heat. This source may be any system that creates heat and requires the removal of said heat to function correctly, such as:- Mechanical,- Electrical,- Chemical,- Nuclear,- Solar,- Friction.

2. Heat transfers away from the source. Heat pipes can also aid in this process, but we'll cover those components separately. In direct heat sink-contact applications, heat moves into the heat sink and away from the source via natural conduction. The heat sink material's thermal conductivity directly impacts this process. That's why high thermal conductivity materials such as copper and aluminum are most common in the construction of heat sinks. 

3. Heat distributes throughout the heat sink. Heat will naturally travel through the heat sink via natural conduction moving across the thermal gradient from a high temperature to a low-temperature environment. This ultimately means that the heat sink's thermal profile will not be consistent. As such, heat sinks will often be hotter towards the source and cooler towards the sink's extremities. 

4. Heat moves away from the heat sink. This process relies on the heat sink's temperature gradient and its working fluid―most commonly air or a non-electrically-conductive liquid. The working fluid passes across the surface of the warm heat sink and utilizes thermal diffusion and convection to remove heat away from the surface and into the ambient environment. This stage relies on, yet again, a temperature gradient to remove heat from the heat sink. Therefore, if the ambient temperature is not cooler than the heat sink, no convection and subsequent heat removal will occur. This step is also where the total surface area of the heat sink becomes most advantageous. A large surface area provides an increased area for thermal diffusion and convection to occur. 

Active Heat Sinks vs. Passive Heat Sinks.Heat sinks are most commonly utilized in active, passive or hybrid configurations.
