Product Description
This graphene copper foil cooling patch is specially designed for smartphone thermal management, especially for gaming phones suffering from severe overheating during long gameplay, video recording and high-load operation.This composite sheet adopts dual-layer thermal structure: pure copper foil rapidly absorbs heat from phone hotspot, and the outer graphene layer spreads heat evenly over the whole surface to eliminate localized high temperature. It effectively reduces phone thermal throttling and maintains stable performance.
✨ Advantages for Mobile Phone
✅ Dual-direction heat conduction design. Copper quickly absorbs internal heat; graphene homogenizes temperature to avoid concentrated hotspots.✅ Built-in self-adhesive backing with release paper, easy installation, no extra thermal glue required.✅ Graphene coating protects copper foil from oxidation and discoloration for long service life.✅ Ultra-thin & flexible, fits phone inner space perfectly without adding bulk.✅ Pre-cut custom phone sizes available, also can be cut freely for other electronic devices.
📱 Installation Steps for Smartphone
- Power off your phone and open the back cover, clean the surface of the heat source area, remove dust and residual adhesive.
- Turn to copper foil side, peel off the white release paper to expose the adhesive.
- Stick the adhesive copper foil side onto the phone’s heating area (CPU/SoC region). Press firmly and squeeze out bubbles to achieve full contact.
- Important: Copper foil side touches the phone heat source, black graphene surface faces outward to dissipate heat.
- Reassemble your phone, finish installation.
⚠️ Important Reminders for Mobile Installation
The copper foil layer is conductive. Keep copper away from exposed circuit pins, batteries and solder points to prevent short circuit and hardware damage.This is passive heat spreading patch, it cannot produce active refrigeration. For heavy gaming scenarios, combining with external phone cooler will get better cooling result.Make sure the bonding surface is clean and dry before pasting, otherwise thermal conductivity and adhesion will decrease.
📌 Application
Gaming smartphones, regular mobile phones, cell phone heat modification, reduce overheating during gaming, video shooting and charging.
