Flat Copper Heat Pipe for Laptop CPU & GPU Heatsink Repair — Sintered Wick, Liquid-Filled When your laptop starts throttling under load or shutting down from heat, a damaged or degraded heat pipe is often the culprit. DIY repair technicians, electronics hobbyists, and professional refurbishers who need a reliable replacement flat copper heat pipe will find this sintered-wick tube a direct-fit solution for restoring full thermal performance to laptops, mini-PCs, and compact electronics. Each listing is for one (1) individual flat copper heat pipe. The pipe features a sintered copper wick structure with a sealed liquid working fluid, a flat profile 8.0mm (≈5/16") wide, available in 2.5mm or 3.0mm thickness depending on the selected variant, and lengths ranging from 50mm (≈2.0") to 450mm (≈17.7"). The outer surface has a polished copper finish as shown in the product image. Typical use cases include laptop CPU and GPU heatsink repair, custom DIY cooling solutions for embedded systems and SBCs, and thermal management upgrades in compact desktop builds where a flat copper heat pipe for CPU cooling is required. 🔵 Compatibility Note: These flat heat pipes are designed to match standard OEM laptop heatsink dimensions. Always measure your original pipe (width, thickness, and length) before selecting a variant. Most slim ultrabooks use 2.5mm thickness; standard laptops and desktop coolers typically use 3.0mm. ✅ Key Features of These Flat Copper Heat Pipes 🔥Sintered Copper Wick Structure — The sintered powder wick provides strong capillary action for reliable passive heat transfer, making this flat copper heat pipe for laptop CPU repair more effective than grooved-wick alternatives at low temperature differentials. 📐Precise Flat Profile — At 8.0mm wide with 2.5mm or 3.0mm thickness options, these pipes match the most common OEM flat heat pipe dimensions found in consumer laptops and compact electronics. 📏Wide Length Selection — Available from 50mm (≈2.0") to 450mm (≈17.7") across 23 variants, covering the full range of laptop and mini-PC heatsink configurations without the need for custom cutting in most cases. ⚡Sealed Liquid-Filled Design — Each pipe is factory-sealed with a working fluid and tested for leak integrity, enabling efficient two-phase heat transport for CPU and GPU thermal management without any maintenance. 🛠️DIY Repair Ready — Designed for technicians replacing degraded or physically damaged heat pipes in laptop heatsink assemblies; the polished copper surface bonds well with thermal paste and solder for heatsink fin attachment. ♻️Extends Device Lifespan — Replacing a failed heat pipe restores the original thermal design intent of the device, reducing thermal throttling and extending the usable life of laptops and compact electronics rather than replacing the entire unit. 📐 Technical Specifications — Flat Copper Heat Pipe Product Type Flat Sintered Copper Heat Pipe Material Copper (tube body & sintered wick) Working Fluid Sealed liquid (deionized water or equivalent) Wick Structure Sintered powder copper wick Width 8.0mm (≈5/16") Thickness 2.5mm or 3.0mm (see variant options) Available Lengths 50mm–450mm / ≈2.0"–17.7" (see variant options) Surface Finish Polished copper Quantity per Order 1 piece Typical Application Laptop CPU / GPU heatsink repair, DIY cooling Thermal Capacity (typical) Generally 15–40W depending on length and orientation Compatible Devices Contact us to confirm for your specific model ⚠️ Before You Order: Measure your original heat pipe's width, thickness, and length carefully. The pipe tip/nozzle end (visible in the product image) is the fill/seal point and is a normal feature of the manufacturing process — it does not affect thermal performance. ❓ Frequently Asked Questions How do I choose the right length for my heat pipe? Measure the distance between the heat source (CPU/GPU die) and the heatsink fin stack on your specific laptop or device. Choose a length that spans that distance with minimal bending. Available lengths range from 50mm (≈2.0") to 450mm (≈17.7"). When in doubt, size up slightly — heat pipes can be trimmed and re-sealed by experienced technicians, but generally it is easier to work with a pipe that is slightly longer than needed. What thickness should I choose — 2.5mm or 3.0mm? Check the thickness of the original heat pipe in your device before ordering. Most slim ultrabooks and thin-and-light laptops typically use 2.5mm flat heat pipes, while standard-thickness laptops and desktop CPU coolers generally use 3.0mm pipes. The 5cm, 25cm, 35cm, 40cm, and 45cm variants are available in 3.0mm only; all other lengths offer both 2.5mm and 3.0mm options. What is the thermal transfer capacity of these heat pipes? Sintered copper heat pipes of this flat profile (8mm wide) typically handle 15–40W of continuous heat flux depending on length, orientation, and working fluid fill. They are generally sufficient for laptop CPU and GPU thermal management in the 15–65W TDP range. For higher TDP applications, consider using multiple pipes in parallel. Can these heat pipes be used in outdoor or high-humidity environments? Copper heat pipes are naturally resistant to corrosion in typical indoor electronics environments. However, they are not designed for prolonged exposure to moisture, salt spray, or outdoor conditions. For outdoor or industrial applications, additional protective coatings or enclosures are recommended. Are these heat pipes compatible with standard laptop heatsink assemblies? These flat copper heat pipes are designed to be compatible with the standard flat-pipe heatsink assemblies found in most laptops and compact electronics. The 8mm width and 2.5/3.0mm thickness match the most common OEM specifications. Always verify your device's original pipe dimensions before purchasing. Do I need special tools to install a replacement heat pipe? Installing a replacement heat pipe typically requires disassembling the laptop or device, removing the old heatsink assembly, and soldering or pressing the new pipe into place. You will generally need thermal paste, precision screwdrivers, and soldering equipment if the pipe is soldered to the heatsink fins. This is an intermediate-to-advanced DIY repair task. What working fluid is inside the heat pipe? These heat pipes use a sealed liquid working fluid (typically deionized water or a similar low-boiling-point fluid) combined with a sintered copper wick structure. The sintered wick provides capillary action to return condensed fluid to the evaporator end, enabling passive, pump-free thermal transfer. 🛒 Select your length and thickness above, then add to cart.
