Vorteile von Druckgusskühlkörpern
Die Verwendung von Druckgusskühlkörpern zur effektiven Kontrolle der von elektrischen Komponenten erzeugten Wärme hat mehrere Vorteile. Im Folgenden finden Sie eine Zusammenfassung der wichtigsten Vorteile, die Druckgusskühlkörper zu einer empfehlenswerten Option machen:
- Hohe Wärmeleitfähigkeit: Druckgusskühlkörper werden aus Materialien mit hervorragender Wärmeleitfähigkeit hergestellt, z. B. aus einer Aluminiumlegierung. Dies ermöglicht die schnelle Übertragung von Wärme auf den Kühlkörper, was die Wärme effektiv von den elektronischen Komponenten ableitet und zur Aufrechterhaltung einer optimalen Betriebstemperatur beiträgt.
- Komplexe geometrische Formen: Die inhärenten Verarbeitungseigenschaften von Aluminiumlegierungen in Verbindung mit dem Druckgussverfahren ermöglichen die Herstellung komplizierter geometrischer Formen. Diese Flexibilität verbessert den Luftstrom und die Oberfläche, wodurch die Gesamtleistung der Wärmeableitung von druckgegossenen Aluminiumkühlkörpern erhöht wird.
- Präzision und Gleichmäßigkeit: Druckguss ist eine präzise Fertigungstechnik, die eine zuverlässige Herstellung von Kühlkörpern garantiert. Die Aufrechterhaltung einer gleichmäßigen thermischen Leistung über ein breites Spektrum von Kühlkörpern hängt von dieser Konsistenz ab.
- Effiziente Serienproduktion: Das Druckgussverfahren erweist sich als wirtschaftliche Methode zur Herstellung von Kühlkörpern in großen Mengen. Es eignet sich aufgrund seiner effektiven und schnellen Produktionsmöglichkeiten, die letztlich die Stückkosten senken, für die Großserienfertigung.
- Ausgezeichnete Optionen für die Oberflächenbehandlung: Fertige Druckgusskühlkörper lassen sich leicht polieren, um ihr Aussehen zu verbessern und ihre Witterungsbeständigkeit zu erhöhen. Weitere Methoden zur Verbesserung der Korrosionsbeständigkeit sind Lackierung, Pulverbeschichtung und Eloxierung.
- Geringes Gewicht: Da Kühlkörper aus leichten Materialien (Aluminiumdruckguss und Zinklegierungen) hergestellt werden, eignen sie sich für Anwendungen, bei denen das Gewicht eine Rolle spielt (z. B. in der Automobil- oder Luftfahrtindustrie).
- Ausreichende elektrische Leitfähigkeit: Aluminium ist eines der Materialien, aus denen Kühlkörper hergestellt werden, und es hat eine hohe elektrische Leitfähigkeit. Anwendungen, die eine effiziente elektrische Erdung oder Leitfähigkeit erfordern, profitieren von dieser Eigenschaft.
- Beständigkeit und Langlebigkeit: Druckgussmaterialien wie Zink- und Aluminiumlegierungen sind für ihre Robustheit und Korrosionsbeständigkeit bekannt. Kühlkörper haben eine längere Lebensdauer, was zum Teil auf ihre Langlebigkeit zurückzuführen ist, die eine zuverlässige Leistung garantiert.
- Anpassungsmöglichkeiten: Der Druckguss ermöglicht die individuelle Anpassung von Kühlkörperdesigns an spezifische thermische Anforderungen. Ingenieure können das Rippendesign, die Größe und die Form ändern, um die spezifischen thermischen Anforderungen einer bestimmten Anwendung zu erfüllen.
Zusammenfassend lässt sich sagen, dass Druckgusskühlkörper Haltbarkeit, Kosteneffizienz, Designfreiheit und thermische Effizienz nahtlos miteinander verbinden. Aufgrund dieser Vorteile sind sie eine beliebte Option für verschiedene elektrische Geräte und Anwendungen, bei denen eine effiziente Wärmeregulierung wichtig ist.

Aluminum heat sink housing are various shells made of aluminum alloy. They are highly flexible and can be cut to any length. The convenience is unmatched by other types of shells. And aluminum is a material with good thermal conductivity, so it has Very good heat dissipation.
Aluminum material selection for heat sinks
In the current market, the main material used for aluminum housing products is aluminum alloy. Aluminum alloy has good thermal conductivity and is strong and durable. Of course, the base made of aluminum alloy can better absorb and dissipate heat.
6063 aluminum profile heat sink technology:
Aluminum profile extrusion manufacturers develop corresponding molds to heat the aluminum ingot to a certain temperature to change its physical shape to obtain aluminum heat sink materials.
Then after coming out of the mold, we get the various types of heat sink profiles we want; then we can cut, groove, polish, deburr, clean, and surface them before they can be used.
6063 aluminum profile heat sink principle:
First: 6063 aluminum profile heat sink has very strong thermal conductivity
Aluminum has strong thermal conductivity and can very well help electronic products dissipate heat. As far as the aluminum profile heat sink material is concerned, the thermal conductivity of each material is different. They are arranged from high to low according to the thermal conductivity. differences are:
Copper, aluminum, steel. However, if silver is used as a heat sink, it will be too expensive, so the best solution is to use copper. Although aluminum is much cheaper, its thermal conductivity is obviously not as good as copper (about 50% of that of copper) ).
The commonly used materials for aluminum profile heat sink are copper and aluminum alloys, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but is more expensive, difficult to process, overweight, has small heat capacity, and is easily oxidized.
Aluminum is too soft and cannot be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but its thermal conductivity is much worse than copper. Some heat sink have different Take the long answer and embed a copper plate on the aluminum alloy radiator base. This can not only take care of the price issue, but also ensure the quality of heat dissipation.
Second: The density of 6063 aluminum profile heat sink is smaller and easier to process into other parts.
Simple installation and convenient maintenance. Since aluminum alloy has low density and can be made into parts of various shapes and specifications, the cross-section of this kind of aluminum profile radiator is large and regular, and product assembly and surface treatment can be carried out in one step.
The steps are in place and can be installed directly at the construction site, saving large installation costs and making maintenance more convenient.
Third: 6063 aluminum radiator has strong plasticity
The 6063 aluminum radiator can be subjected to various surface treatments, with many colors and varieties, and no solder joints. It is highly decorative, beautiful and durable, and can meet people’s personalized requirements. Yongyu Metal can also process sandblasting, drawing, polishing
Light, surface anodizing, hard oxidation and other processing techniques can produce more beautiful aluminum radiators.
Radiators made of 6063 aluminum profiles have strong thermal conductivity, low density and low price, so they are loved by major manufacturers.
Other functions of aluminum alloy heat sink:
- Anti-electromagnetic radiation: The solid shell protects the board, power supply and storage equipment, and can prevent pressure, impact, and dust. It can also perform the function of preventing electromagnetic interference and radiation, and shielding electromagnetic radiation.
- Low density: The density of the aluminum alloy shell is very small. The container is easy to make and can be used as a mobile phone shell and charging shell. It is also very wear-resistant and anti-corrosion. A dense aluminum Oxide film is easily formed on the surface of the aluminum alloy shell to prevent nutrient growth.
- Storage devices: It can provide space for power supplies, motherboards, various expansion boards, floppy disk drives, optical disk drives, hard disk drives and other storage devices, and is connected through supports, brackets, various screws or clips inside the chassis . The components securely fix these parts inside the chassis to form an intensive whole.
- High strength: The aluminum alloy shell can effectively improve the hardness of the aluminum shell after aging treatment. The aluminum profile shell after rough surface treatment not only takes into account the heat dissipation performance, but also takes into account the appearance.
- Light weight. Only one-third the weight of a cast iron radiator with the same heat dissipation. Light weight, easy to install and carry. When the heat dissipation is the same, its weight is only one-tenth that of a cast iron radiator, one-sixth that of a steel radiator and one-third that of a copper radiator, which can greatly save transportation costs, reduce labor intensity, and save Install time.
- Safe and reliable. Safe and reliable, high thermal efficiency, good thermal conductivity, energy-saving and environmentally friendly, and long service life.
- Corrosion resistance. The surface of the aluminum die-cast heat sink is degreased, oxidized and then spray-coated to ensure that the coating will not fall off for a long time and is impact resistant. A thick oxide film can be formed on the surface of aluminum alloy materials and can be used for heating water with pH ≤ 9 or for long-term use in automobile water tanks. Aluminum heat sinks with special surface treatment can be used in various pH~12. This material is used for a long time.
- Beautiful. The aluminum die-cast heat sink has a simple, beautiful, elegant yet fashionable design, is small in size, light in weight, and easy to install, inheriting the excellent European radiator production technology. Cooling fins are available in a variety of surface finishes. It has a variety of patterns and colors, no solder joints, strong decoration, beautiful and durable, and can meet people’s personalized requirements.
- Wide application. Widely used in automobiles, LED, etc., mechanical equipment, electronic equipment, motor body shells and other industries.
- Dimensions are variable. Beautiful appearance, flexible size. It can be an artistic shape, or it can be customized according to the special requirements of special rooms and users to show your personality; it is easy to match and coordinate with the room, making it a perfect home decoration product.
- High strength. Die-cast aluminum radiators have high overall strength and high working pressure, so they are suitable for high-rise buildings because the specific strength and specific stiffness of aluminum alloys are much higher than those of copper, cast iron and steel. Even though it is thin, it can withstand sufficient pressure, bending force, traction and impact force, and will not be damaged during handling, installation and use.
- Easy to install. Module combination, easy to install. Due to the low density of aluminum alloy, it can be processed into parts of various shapes and specifications. This kind of aluminum radiator has a large and regular cross-section. The product assembly and surface treatment can be done in one step. It can be installed directly at the construction site, saving a lot of installation costs. Maintenance is also very convenient and cheap.
- Energy saving and consumption reduction, low cost of use. When the center distance of the radiator inlet and outlet is the same as the heat conduction temperature, the aluminum radiator is 2.5 times more dispersed than the cast iron radiator, and cannot be heated due to its beautiful appearance. It can reduce heat loss by more than 30 inches and reduce costs by 10 inches. Although the cooling effect of the above aluminum radiator is slightly not as good as that of the copper radiator, the weight can be greatly reduced. Since the price of aluminum is only 1/3 of the price of copper, it can greatly reduce costs.
Aluminum die-cast heat sinks are widely used in automotive engines, electronic equipment, industrial machinery and other fields. For example, the radiator on a car engine needs to use aluminum die-casting fins to dissipate heat to ensure the normal operation of the engine.
The manufacturing process of aluminum die-casting heat sink mainly includes the following steps:

When designing an aluminum die-cast heat sink enclosure, engineers usually consider the following aspects: enclosure size, heat dissipation power, fan configuration, and installation method.
- Housing size is very important. It needs to be determined based on the size and number of cooling elements. The size of the casing will directly affect the cooling capacity of the radiator. If it is too small, it will result in insufficient heat dissipation, and if it is too large, it will waste materials and costs.
- The heat dissipation power is an important consideration for aluminum die-casting heat sinks. The amount of heat dissipation power is closely related to the heat dissipation power of the internal heat dissipation components and the working status of the fan. Therefore, when designing the casing, sufficient space for heat dissipation and sufficient air flow must be ensured to ensure the heat dissipation effect.
- Fan configuration is another important factor to consider when designing an aluminum die-cast heat sink. It is necessary to ensure that air can flow through the entire radiator, taking into account noise and power consumption.
- The installation method is the last important factor in aluminum die-casting heat sink design. Different installation methods will affect the heat dissipation effect and practicality of the radiator. By choosing the correct installation method, the radiator can be more stable and reliable in operation, and can also be more conveniently maintained and replaced.
In short, aluminum die-cast heat sink is one of the important parts of the radiator, and its design plays a very important role in the performance and practicality of the radiator. Through reasonable size design, cooling power calculation, fan configuration and excellent installation methods, users can be provided with more efficient, safe and reliable cooling solutions.
