Custom heat sink is a kind of equipment used for radiating heat, which is made of thermally conductive material. Its main function is to distribute the heat generated by electronic equipment and mechanical equipment to ensure the normal operation of the equipment. Heat sinks usually include heat sinks, fans and other components, through which the temperature of the equipment can be effectively reduced.
Custom heat sink is an important component to ensure the normal operation of the equipment, it can be the equipment generated by the excessive heat dissipation, to ensure stable operation of the equipment. If the equipment is working at too high a temperature for a long time, it will cause damage to the equipment, resulting in a shorter lifespan of the equipment, and may even lead to more serious safety hazards. Therefore, the role of the heat sink is indispensable in many fields.
As a device used to dissipate heat, the application range of Custom heat sink is very wide, from ordinary household appliances to automobiles, industrial production areas have applications. It plays an important role in ensuring the normal operation of equipment and extending its life. Our customized heat sinks provide efficient heat dissipation solutions for a wide range of electronic devices and industrial applications, ensuring stable equipment operation.
The commonly used materials for making customized heat sinks include metal materials, ceramic materials and plastic materials.
Metal
Metal materials are one of the main materials used to make heat sinks. Commonly used metal materials include aluminum, copper, iron, stainless steel and so on. Aluminum is one of the most commonly used heat sink materials because it has good thermal conductivity, formability and corrosion resistance. Copper has better thermal conductivity and corrosion resistance, but the cost is relatively high.
Ceramics
Ceramic material is one of the relatively new heat sink materials. Ceramic heat sinks have good thermal conductivity, mechanical strength and corrosion resistance, and are easy to mold. Compared with metal materials, ceramic materials also have better insulating properties, so more applications in some special electronic equipment.
Plastic
Plastic materials are another option for making heat sinks, and the commonly used plastic material is Polyimide, which has good insulating properties, mechanical strength and thermal stability. Its main advantages are low cost, light weight and easy to mold, so it is more commonly used in some smaller, low-power electronic devices.
Different heat sink materials have their own advantages and disadvantages, so you need to choose according to your projects. For example, in the high-power large-scale electronic equipment, you need to use a better thermal conductivity of metal materials to produce heat sinks, while in some smaller, low-power electronic equipment can be considered to use plastic materials or ceramic materials to produce heat sinks. In addition, it is also necessary to design the heat sink according to the characteristics of different materials to ensure that the heat sink can effectively dissipate heat.
The processing technology of the heat sink mainly includes CNC, Aluminum Extrusion, die-casting, Skived Fin, Insert Type etc.
Aluminum Extruded Heat Sinks
Aluminum extrusion: Aluminum extrusion heat sink is made by heating the aluminum ingot to about 460℃, letting the semi-solid aluminum flow through the extrusion die with grooves under high pressure, extruding the initial shape of the heat sink, and then cutting and further processing.The aluminum extrusion process does not accurately guarantee dimensional requirements such as flatness of the heat sink, so further processing is usually required at a later stage.
1. Aluminum extruded heat sink tooling costs can be spread out to each heat sink, making it less costly for mass production applications;
2. The ratio of tooth height and tooth spacing (Z/X) is limited and usually not recommended to exceed 15.
Die Casting Heat Sinks
Die-casting: die-casting is a processing method in which a molten alloy liquid fills the cavity of a steel mold at high speed under high pressure and causes the alloy liquid to solidify under pressure to form a casting; die-cast heat sinks, as shown in the figure below, are not precise enough in size, do not have a polished surface (with little heat radiation) and have a complex stellar body, which requires further processing at a later stage;
1. The cost of die-casting heat sink mainly lies in the die-casting mold, raw materials, machining and surface treatment, etc., and its mold cost is higher, suitable for mass production occasions (apportionment of the cost of the mold);
2. Die-casting heat sink form is more diverse than aluminum extruded heat sink, but the heat dissipation performance is relatively worse.
Skived Fin Heat Sinks
Skived fin: Skived fin is a long strip of sheet metal through mechanical action, into a certain angle will be cut into the material sheet and straighten, repeated cutting to form an arrangement has been the fin structure, as shown in the figure below; Skived fin heat sink no mold costs, applicable to small batch production needs of the occasion, the production cost is mainly: raw materials, Skived fin, CNC machining, surface treatment, and so on;
Aluminum alloy and copper are commonly used Skived fin heat sink materials.
1. Skived fin heat sink is a little bit of width is not particularly limited, the fins can be processed thickness of 0.2mm, height of 100mm, tooth spacing of up to 6mm;
2. Compared to the extrusion process, the advantage of Skived fin is that you can process a greater density of fins, and tooth height multiplier ratio is greater than the heat sink, and thus in the limited space can have a relatively large area of heat dissipation, more suitable for the use of forced air-cooled cooling occasions;
Inserted Heat Sinks
Inserted heat sink processing is inserted fins into the heat sink substrate, the use of adhesive welding, brazing or extrusion and other means of connecting the fins with the substrate; as shown in the figure below, due to the inserted fin involved in the processing of the fins and the substrate for the two independent parts, the substrate and fins are mostly used in aluminum alloys (different alloys): the substrate can be used in the CNC processing of the fins of the groove, fins can be used in the slit-cutting. The combination of the fins and the substrate of the gear heat sink is very important; if not handled properly, a certain contact thermal resistance may be formed, affecting the heat dissipation performance of the gear heat sink. Finned heat sink cost of raw materials accounted for a large proportion of its in a small space can have a large area of heat dissipation, suitable for forced air-cooled heat sink applications.
Size
Customized size and specification is available according to your projects to assure the adaptation of the heat sink and product.
Shape
Square, circle, semicircle, retangle, irregular shape are available as long as there are drawing files.
Surface Finish
Anodized, sand blasting, brushed, spraying etc. according to the application of the heat sinks.
