Core Product Overview

Heat-spreading graphite film is an advanced thermal management material built on a highly oriented graphite crystal structure. It utilizes bidirectional heat conduction technology to enable rapid lateral heat diffusion and vertical heat transfer, overcoming the heat dissipation limitations of traditional materials. Its core value lies in delivering ultra-high thermal conductivity in an ultra-thin (micrometer-level), lightweight form while maintaining flexibility, making it suitable for complex curved surfaces and confined spaces.

Widely Used

The application logic of Heat Spreading Graphite Film is very clear: any electronic device with limited space and high heat generation is its main battlefield. It does not directly dissipate heat, but acts as a "heat transporter" to quickly spread out local high temperatures.

1. Consumer electronics (largest application area)

This is the most mature market for graphite film, mainly solving the contradiction between "performance and lightness".

Smartphone/tablet: attached to the back of SoC (main chip), 5G RF chip, and screen driver IC to prevent overheating and frequency reduction during gaming or fast charging.
Laptop/ultrabook: Covering the surface of the CPU, GPU, and heat pipe to assist in uniform heating and reduce fan startup noise.
Wearable devices (watches/VR): Utilizing their ultra-thin characteristics (<0.03mm), they can dissipate heat in extremely small spaces, avoiding skin burns.

2. Communication and Data Center (High Power Scenario)

5G base station AAU (active antenna unit): 5G antennas have high power consumption and are usually sealed without fans. Graphite film is used to conduct the heat of the power amplifier (PA) to the housing.
Optical module: The internal laser of the high-speed optical communication module generates dense heat, and graphite film is used for thermal diffusion.
Server motherboard: Perform local equalization around the CPU and memory modules to improve operational stability.

3. New Energy and Automotive Electronics (Fastest Growing Blue Ocean)

Thermal management of power batteries: As a thermal pad attached between the battery cells, it helps balance the temperature of the entire battery pack and prevent local overheating (in conjunction with the bipolar plate material you previously learned about, which is another major application of graphite material in new energy vehicles).
Car display screen/central control: solves the problem of heat accumulation in high temperature environments for high brightness screens.
BMS (Battery Management System) main control board: protects the main control chip from high temperature effects.

4. High end Industry and Medical

Medical endoscope/portable device: It is required to be non-magnetic and free of metal ion precipitation, and the chemical inertness of graphite is an advantage.
Industrial laser/drone flight control: Dealing with pulse heating caused by instantaneous high current.

Solutions And Customized Services Provided

1. Resolve the risk of "localized high-temperature burning" (uniform heating)

This is its most core value. Traditional heat sinks do not conduct heat quickly enough, which can easily lead to local "hot spots" in chips such as CPUs and 5G PA. Long term high temperatures can cause performance degradation and even hardware damage.

Graphite solution: Utilizing its extremely high planar thermal conductivity (>1000 W/m · K), the concentrated point heat source is instantly "flattened" across the entire plane, rapidly lowering the 80 ℃ hot spot to 50 ℃, eliminating temperature differences, and protecting core components.

2. Breaking through the physical limitations of limited space

There is almost no space left for heat dissipation fins inside mobile phones, tablets, and drones, and traditional metal heat dissipation fins or heat pipes cannot be inserted.

Graphite solution: Extremely thin and light (10-100 μ m), attached to the shielding cover or middle frame like a piece of paper, without occupying the Z-axis height, perfectly adapted to the structural design of ultra-thin devices.

3. Realize "lightweight" and "noise free" heat dissipation

In aerospace, automotive electronics, or high-end laptops, weight and noise are hard indicators. Fans or heavy metal heat sinks can increase weight and power consumption.

Graphite solution: With a density only 1/4 of copper, it has a significant weight reduction effect. As a passive heat dissipation material, it is completely silent and has no moving parts, making it highly reliable.

4. Compatible with the requirements of "flexibility" and "ease of processing"

Modern circuit board layouts are complex, and the heat dissipation path often needs to be bent. Metal materials are prone to fatigue fracture and have high processing costs due to repeated bending.

Graphite solution: With excellent flexibility, it can be molded into any shape (FPC form), and can be attached according to the shape, making it easy to automate assembly and greatly reducing assembly difficulty.
