Graphite Thermal Sheet

Graphite Sheet for Sale

The graphite thermal sheet is mainly a rectangular or square shaped pressed part. Depending on your specific needs, they will be processed to fit your size requirements.

Advantages of graphite thermal sheet

The graphite thermal sheet is generally in the shape of a plate, and its advantages are very prominent.

High thermal conductivity. The heat can be quickly and evenly transmitted in the plane, effectively avoiding local overheating;

Good high temperature resistance. It can work stably in a wide temperature range of -100 °C to 600°C, adapt to a variety of extreme thermal environment;

Strong chemical stability. Not easy to react with most substances, can maintain stable performance in corrosive environment such as acid and alkali;

Low coefficient of thermal expansion. Small size change in the process of temperature change, to ensure a close fit with other components;

High flatness. It is easy to closely fit with heat source or heat dissipation object, reduce thermal resistance, improve heat transfer efficiency.

Excellent thermal conductivity. This is indispensable in the application scenarios of various electronic equipment heat dissipation, industrial heating and temperature control, and can accurately regulate the temperature to ensure the stable operation and efficient work of the equipment.

Specifications of graphite thermal sheet

Graphite thermal sheets mainly have the following categories.

Classified by graphite purity:

Ordinary purity graphite thermal sheet. Carbon content is roughly 98%, can meet the general industrial heating and conventional heat dissipation needs.The cost is relatively close to the people, often used in consumer electronic equipment heat dissipation, small industrial heating devices and other scenarios;

High purity graphite thermal sheet. Carbon content of up to 99.5% and above, suitable for demanding purity and thermal conductivity environment. Such as high-end electronic chip heat dissipation, aerospace equipment thermal control system.

Classified by manufacturing process:

Extruded graphite thermal sheet. Manufactured by extrusion molding process, it has high mechanical strength and better anisotropic thermal conductivity. You can adjust thermal conductivity characteristics according to different extrusion directions. Suitable for occasions where there is a specific direction of thermal conductivity needs;

The molded graphite thermal sheet. This is pressed by a mold, can achieve a more complex shape design and is easy to integrate with specially structured equipment. And you can often use it in customized thermal management solutions.

If you want to know more about thermal conductivity, we will give you the corresponding guidance and provide more reference advice. In addition, you can choose from sintered graphite thermal sheets, impregnated graphite thermal sheets, composite graphite thermal sheets or other types of graphite thermal sheets.

Uses of graphite thermal sheets

Electronic equipment field:

Chip heat dissipation. In computer CPU, GPU and other chip heat dissipation module, graphite thermal sheet can quickly spread the heat generated by the chip. Ensure the stable operation of the chip within the safe temperature range, improve the performance and service life of electronic equipment;

Mobile phone heat dissipation. As the internal heat dissipation component of the mobile phone, it effectively reduces the temperature of the mobile phone due to long-term use or high-performance operation. This avoids problems such as frequency reduction and stalling caused by overheating, and improves the user experience.

Industrial manufacturing:

Heating platform. In the plastic processing, electronic component welding and other industrial production process, you can use graphite thermal sheet as a uniform heating platform. Precise control of heating temperature and area, improve product production quality and process stability;

Hot pressing die. Used in the hot pressing process of composite materials, it can provide uniform and stable heat to ensure the quality consistency of composite materials in the molding process.

In the field of new energy:

lithium battery thermal management. In the lithium battery pack of electric vehicles, the graphite thermal sheet can effectively control the heat dissipation and temperature balance of the battery module. Prevent the battery from causing safety risks due to overheating, extend the battery life, and improve the overall performance and reliability of the battery system.
