Spatula Radiator

Product introduction

The spatula radiator is mainly composed of two parts: bottom plate and spatula teeth. The bottom plate is usually made of metal materials with high thermal conductivity, such as aluminum alloy, whose role is to quickly absorb the heat generated by the heat source. The shovel teeth part is processed by special processing technology to produce rows of closely arranged tooth-like structures on the bottom plate. These tooth-like structures greatly increase the contact area between the radiator and the air, when the heat is transferred to the shovel teeth, the air flows between the teeth, and the heat is dissipated to the surrounding environment through heat conduction and heat convection, so as to achieve efficient heat dissipation.

Take the computer CPU radiator as an example, when the CPU is in a high load running state, it will generate a lot of heat. The bottom plate of the spatula radiator is tightly fitted to the CPU surface, and the heat is quickly transmitted to the entire radiator. Due to the existence of the shovel teeth, compared with the static air, the flowing air can take away the heat faster, so that the temperature of the CPU can be maintained in a safe and stable range, to ensure the normal operation of the computer, to avoid performance degradation and even hardware damage caused by overheating.

Material selection of shovel radiator

Aluminum alloy: Aluminum alloy is one of the most commonly used materials for shovel teeth radiator. It has good thermal conductivity and can quickly conduct heat from the heat source to the entire radiator structure. At the same time, the density of aluminum alloy is relatively low, which makes the radiator have a light weight on the premise of ensuring the heat dissipation performance, which is easy to install and use in all kinds of electronic equipment, and will not add too much burden to the equipment. Moreover, the processing technology of aluminum alloy is mature, easy to process complex structures such as shovel teeth, and the cost is relatively controllable, which makes aluminum alloy shovel teeth radiator has a high cost performance in the market, and is widely used in consumer electronics, communication equipment and other fields.

Copper: The thermal conductivity of copper is higher than that of aluminum alloy, and in some occasions with high heat dissipation requirements, such as high-end servers, power electronic equipment, copper tooth radiators will be used. Copper can transfer heat more quickly, further improving the efficiency of heat dissipation. However, the density of copper is relatively high, the cost is relatively high, and it may face some technical difficulties during processing, such as work hardening, which limits its use in some cost - and weight-sensitive application scenarios to a certain extent. But for those who pursue extreme heat dissipation performance and are not too sensitive to cost of high-end equipment, copper shovel tooth radiator is undoubtedly an ideal choice.

Processing technology of shovel tooth radiator

Precision machining: The processing of the shovel radiator usually adopts precision machining technology, through the use of high-precision cutting tools, the shovel structure is gradually processed on the bottom plate according to the design requirements. This processing method can ensure the dimensional accuracy and shape accuracy of the shovel teeth, so that the spacing between the teeth is uniform, the height and Angle of the teeth are consistent, so as to ensure the air flow between the teeth is uniform and stable, and improve the heat dissipation effect. At the same time, precision machining can also achieve complex tooth shape design, such as according to different heat dissipation needs, processing different shapes and angles of the teeth, further optimize the heat dissipation performance.

Surface treatment process: In order to improve the heat dissipation performance and corrosion resistance of the radiator, a series of surface treatment processes will be carried out after the processing of the shovel radiator. Common surface treatment methods include anodizing treatment and passivation treatment. Anodizing treatment can form a dense oxide film on the surface of the radiator, which can not only improve the corrosion resistance of the radiator, but also increase the surface roughness, thereby enhancing the radiation heat dissipation capacity and further improving the overall heat dissipation effect. Passivation treatment can remove impurities and pollutants on the surface of the radiator, make the surface cleaner, and facilitate the dissipation of heat and the flow of air.

Advantages of spatula radiators

Efficient heat dissipation performance: The spatula radiator can achieve efficient heat dissipation by increasing the heat dissipation area and optimizing the air flow. Compared with the traditional flat radiator, its heat dissipation efficiency can be increased several times or even higher. In some high-power electronic equipment, the operating temperature of the equipment can be effectively reduced to ensure the stability and reliability of the equipment in high temperature environment or long time high load operation. For example, in the high-power inverter in the industrial automation control system, the temperature of the internal power module can be effectively controlled after the use of the shovel radiator, reducing the downtime caused by overheating and improving production efficiency.

Compact structure: The structure of the shovel radiator is relatively compact, which can achieve efficient heat dissipation in a limited space. This makes it an obvious advantage in some electronic devices with high space requirements, such as laptops, small servers, and so on. In notebook computers, the spatula heat sink can meet the heat dissipation requirements of core components such as CPU and GPU without occupying too much internal space, ensuring that the notebook computer is thin and portable, and has good performance.

High degree of customization: Because the processing process of the shovel radiator is relatively flexible, it can be customized design and production according to different application scenarios and customer needs. According to the shape, size, power and other parameters of the heat source, the matching shovel radiator can be designed, including the number of shovel teeth, height, spacing and the thickness and shape of the bottom plate can be personalized adjusted to achieve the best heat dissipation effect. This customization capability enables the spatula radiator to be widely used in a variety of different types of electronic devices to meet diverse market needs.
