Application of Ceramic Heat Dissipation in Battery Cooling System

At present, the thermal management of power battery systems can be mainly divided into four categories: natural cooling, air cooling, liquid cooling, and direct cooling.

Among them, natural cooling is a passive thermal management method, while air cooling, liquid cooling, and direct cooling are active methods. The main difference between the three is the difference in heat exchange medium.

Traditional battery cooling system: To change the temperature difference between the battery core and the cooling system, liquid cooling system refrigeration is the most useful method.

How does ceramic heat dissipation apply to battery heat dissipation?

What are the Key Factors To Consider in Boron Nitride Atomizer Nozzle Design

Boron nitride atomizer nozzles for powder metal atomization play a crucial role in the atomization process. These nozzles are responsible for converting molten metal into fine powder particles, which are then used in various industries such as automotive, aerospace, and electronics.

There are different types of boron nitride atomizer nozzles used in powder metal atomization, including gas atomizers and water atomizers. Gas atomizers use high-pressure gas to disintegrate a molten metal stream into tiny droplets, which solidify into powder particles as they cool down. Water atomizers, on the other hand, use water jets to break up the molten metal stream into powder particles.

The design and construction of boron nitride atomizer nozzles are critical for ensuring efficient and effective atomization. Some key factors to consider in boron nitride atomizer nozzle design include:

Nozzle geometry: The shape and size of the nozzle play a role in determining the droplet size and spray pattern. Different geometries can be used to achieve specific particle size distributions.
Nozzle material: The material used to construct the nozzle should have high toughness and resistance to wear and corrosion. Common materials include stainless steel, tungsten carbide, and ceramic.
Nozzle cooling: Atomizer nozzles need to withstand high temperatures, and cooling mechanisms such as water jackets or internal channels can be used to prevent overheating.
Nozzle alignment: Proper alignment of atomizer nozzles is crucial for achieving consistent powder particle size and distribution. Precision alignment systems are employed to ensure accurate positioning of the nozzle during atomization.

Boron nitride atomizer nozzles are typically custom-designed to meet specific requirements, such as the desired powder particle size range and production capacity. Advanced manufacturing technologies, such as additive manufacturing, are now being used to produce atomizer nozzles with complex geometries and improved performance.

Boron nitride atomizer nozzles are key components in powder metal atomization, enabling the production of high-quality powder particles used in a wide range of applications.

Boron Nitride Ceramic Amorphous Strips Nozzles For Amorphous Alloy Strip Production

A boron nitride ceramic nozzle is a specialized tool used in the production of amorphous alloy strips. Amorphous alloys are a class of materials with a disordered atomic structure that offers unique electric, magnetic and mechanical properties, and their history counts approximately 40 years.

In recent years, amorphous alloy industry technology have developed rapidly, so higher requirements have been put forward on the nozzle materials used in the key of tape production. The boron nitride composite ceramic material developed for amorphous strip production has excellent high temperature resistance, corrosion resistance, thermal shock resistance, creep resistance and easy processing properties, which can meet the production of various amorphous strips, especially suitable for the needs of broadband amorphous strip production.

During amorphous alloy strips production process, a boron nitride ceramic nozzle is employed to deliver a precise and controlled flow of molten amorphous alloy onto a rotating wheel. The nozzle can withstand high temperatures, corrosive environments and boron nitride ceramic provides excellent thermal conductivity, ensuring proper heat transfer and cooling of the alloy strip. This helps to maintain consistent material properties and prevent deformation during production. The smooth surface of the nozzle also assists in the smooth and uniform deposition of the alloy onto the wheel, resulting in a high-quality final product.

Additionally, boron nitride ceramic has a low coefficient of friction, reducing frictional wear and tear on the nozzle. This results in increased nozzle lifespan and minimized maintenance requirements, contributing to overall cost-efficiency.

Amorphous metal alloy strip is produced by rapidly cooling the melt on a rapidly rotating drum. The manufacturing process is briefly described as follows: Put the “master alloy” into an induction furnace and heat it to the melt temperature of 1200-1300°C, and keep it at this temperature for a certain period of time. The melt is poured into the rotating copper drum through the nozzle, cooled and Separate the ribbon from the roller. The cooling speed reaches 106K/s, and the drum linear speed is 30m/s. Such high melt cooling rates and the presence of amorphizing agents in the melt allow “freezing” of liquid metal without producing crystals. The manufacturing scheme is shown in Figure 1.
