The heat pipe is a heat transfer element with high thermal conductivity. The working principle of the heat pipe: The heat pipe is an artificial component with excellent heat transfer. The commonly used heat pipe consists of three parts: the main body is a closed metal pipe with a small amount of working medium and capillary structure inside, the air and other debris in the pipe Must be excluded.
Three physical principles are used when the heat pipe works:
1. In the vacuum state, the boiling point of the liquid decreases.
2. The latent heat of vaporization of the same substance is much higher than the sensible heat.
3. The suction force of the porous capillary structure on the liquid can make the liquid flow.
Folded fin/Zipper fin + heat pipe heat sink: FIN sheet + heat pipe heat sink is to weld the FIN sheet and the heat pipe through solder paste, and use the heat transfer performance of the heat pipe to quickly transfer the heat. Its heat dissipation efficiency is high and the heat dissipation performance is stable. FIN can be used with copper, It is made of aluminum material, which can reduce product weight and production cost under different performance requirements, and is suitable for mass production.
Skived fin + heat pipe heat sink: The shovel teeth + heat pipe heat sink is a shovel fin and heat pipe welded by solder paste. This production process combines the heat absorption and heat transfer of the heat pipe and the heat dissipation performance of the shovel tooth is very stable. Combined together, the heat is quickly transferred from the heat source to ensure the safe and stable operation of the equipment; compared with the FIN chip + heat pipe heat sink, the cost of mold opening is reduced, and the production quantity is relatively small, which is relatively suitable for small batch and diversified production.
Copper aluminum combination + heat pipe heat sink: the pre-designed copper pipe is embedded and pressed into the aluminum plate with reserved groove, and epoxy resin is used to fill the gap to reduce the thermal resistance of the gap air, and then processed by CNC.
Advantage | Heat Pipe Heat Sink | Traditional Heat Sink |
Thermal Efficiency | Extremely high thermal efficiency due to the phase change process, allowing for rapid heat transfer. | Moderate efficiency, primarily relying on conduction through solid materials. |
Heat Distribution | Evenly distributes heat along its length, preventing hot spots and enhancing overall cooling performance. | May create hot spots if not designed properly, leading to uneven cooling. |
Compact Design | Thin and lightweight, making them ideal for space-constrained environments such as laptops and compact electronics. | Generally bulkier and heavier, requiring more space for effective cooling. |
Passive Operation | Operates without moving parts, requiring no external power source or maintenance, which enhances reliability. | Often relies on fans or active cooling methods, which can introduce noise and require maintenance. |
Long Lifespan | High durability with no moving parts; vacuum-sealed design prevents liquid loss and corrosion. | Mechanical components can wear out over time, leading to potential failures. |
Versatility in Applications | Suitable for a wide range of applications, including electronics, automotive, and aerospace industries due to their adaptability. | Limited to specific applications where traditional conduction metho ds suffice. |
Cost-Effectiveness | While initial costs may be higher, they can reduce long-term operational costs by improving efficiency and reducing maintenance needs. | Lower initial costs but may incur higher operational costs due to less efficient cooling performance. |
