FIN heat pipe radiator 006

Heat pipes are heat transfer components with extremely high thermal conductivity, invented in 1964 at the Los Alamos National Laboratory in the United States. They reached a peak in theoretical research in the late 1960s and began to be widely used in the industrial field in the 1970s. They transfer heat through the phase change of working fluid between gas and liquid within a fully sealed vacuum tube, exhibiting thermal conductivity hundreds of times greater than that of pure copper, earning them the nickname 'thermal superconductor.' A well-designed heat pipe CPU cooler can achieve performance that ordinary air-cooled coolers without heat pipes cannot match.
Heat pipe coolers are new products that utilize heat pipe technology to make significant improvements to many old-style coolers or heat exchange products and systems.
The thermal resistance of heat pipe coolers is determined by the thermal conductivity of the materials and the effective area within the volume. Solid aluminum or copper coolers, when their volume reaches 0.006m3, cannot significantly reduce thermal resistance by further increasing their volume and area. For dual-sided cooling discrete semiconductor devices, the thermal resistance of all-copper or all-aluminum air coolers can only reach 0.04℃/W, while heat pipe coolers can achieve 0.01℃/W. Under natural convection cooling conditions, the performance of heat pipe coolers can be more than ten times better than that of solid coolers.
Heat pipe coolers have the following advantages:
① Fast thermal response speed; their ability to transfer heat is over 1000 times greater than that of copper pipes of the same size and weight.
② Small size and lightweight.
③ High cooling efficiency, which can simplify the cooling design of electronic devices, such as changing from air cooling to self-cooling.
④ No external power supply is needed, and they do not require special maintenance during operation.
⑤ Excellent isothermal properties; after thermal equilibrium, the temperature gradient between the evaporation section and cooling section is quite small and can be approximated as zero.
⑥ Safe and reliable operation without polluting the environment.
