Extrusion heat sink is used in Board-Level cooling solutions
A board level extrusion heat sink, such as the T0-220 type with natural convection, is a heat dissipation device designed for integrated circuit components on the board. This type of heat sink adopts the principle of natural convection and does not rely on external fans. It is usually made of high-quality aluminum 6061/6063-T5 profiles, and a certain groove is made on the heat sink to facilitate heat convection and exchange.Its structural design mainly includes unique fin shapes or block shapes, aiming to maximize surface area and improve heat dissipation efficiency.
Through natural convection, the heat sink can effectively transfer the heat generated on the motherboard to the surrounding air, reducing the temperature of the integrated circuit and ensuring its normal operation.This board level heat sink not only efficiently dissipates heat on limited space boards, but also eliminates the need for external fans, making installation more convenient. Suitable for use in environments that require silent operation or limited space. This heat sink design ensures the stability of the board components and improves the overall reliability of the equipment.
The extrusion heat sink with heat pipe.
The extrusion heat sink wiht heat pipe is an efficient heat dissipation design, achieved by combining profile technology and heat pipe technology. In this scheme, the profile 6063 with high thermal conductivity is first used as the main structure of the extrusion heat sink. The unique shape and structure of the profile increase the surface area, which helps to improve heat conduction and radiation.
Secondly, integrate heating tube technology and embed heat dissipation tubes with good thermal conductivity into profiles. By flowing heat conducting liquid inside the pipe or directly heating the pipe wall, local heating is achieved to accelerate the heat transfer effect of the radiator. This design scheme can not only meet the requirements for efficient heat dissipation, but also achieve local heating when needed, especially for the application of IGBT Cooling with high density and power.The entire scheme cleverly combines profile technology and heating tubes, allowing the radiator to provide strong heat dissipation performance while also possessing more functionality and flexibility.
The thermal solution is used in extrusion heat sink.
The application of thermal analysis in profile heat sinks.Usually, customers consider profile heat sinks because they are cheap and have high production efficiency. However, due to limitations in profile technology, the fin thickness of the heat sink should not be less than 0.5mm and the height should not exceed 80mm. At the same time, the spacing between heat sinks is generally 1/30 of the fin height, which means that for a 30mm high heat sink, the minimum spacing can only be 1mm.
Therefore, in general, fixed space cannot provide heat dissipation efficiency, At this point, thermal analysis can be used to optimize the contact area of the bottom heat source, increase some heat pipes, and the high-efficiency conduction characteristics of the heat pipes can diffuse a large amount of heat, thus achieving the optimal heat dissipation scheme. The simulation analysis of software is based on existing conditions, comparing the increase or decrease of one attribute, and such data is very important for R&D engineers
These advantages of extrusion heat sink.
The extrusion heat sinks are highly favored in the field of heat dissipation due to their unique design and material advantages. Firstly, its main constituent material is usually high thermal conductivity aluminum alloy 6063, which has good thermal conductivity and can quickly conduct and dissipate heat. This enables the profile radiator to effectively reduce temperature while improving heat dissipation efficiency.Secondly, the structural design of the profile heat sink is unique, using aluminum extrusion in the form of flakes or fins, which can effectively increase the heat dissipation surface area.
This design not only improves heat dissipation efficiency, but also reduces overall weight, meeting the requirements of modern equipment for lightweight and efficient heat dissipation.In addition, the appearance design of the extrusion heat sink is flexible and can be customized according to customer needs. This is particularly important in some application scenarios that require high appearance requirements. Meanwhile, its manufacturing process is relatively simple and the cost is relatively low, making it more competitive in the market.Overall, profile heat sinks are widely used in fields such as electronics, automotive industry, LED lighting cooling, etc. due to their strong thermal conductivity, lightweight and flexible design, and beautiful appearance, making them an ideal cooling solution in modern industry.
