Heat Pipes For Electronics Cooling Applications
Heat pipes and thermosyphons energiteknik kth.
Heat pipes for electronics cooling applications. A heat pipe is a heat transfer device that combines the principles of both thermal conductivity and phase transition to effectively transfer heat between two solid interfaces. Although the general guidelines for integrating heat pipes in broader electronics cooling applications still apply to leds their unique thermal. Introduction historically the use of metallic heat sinks has been sufficient to provide the required thermal management for most electronic cooling applications. Currently one of the highest volume applications for heat pipes is cooling the pentiumprocessors in notebook computers.
Learn how act and this technology can reduce costs improve the life of your equipment. Heat pipe patent applications. In fact act is the only us manufacturer that routinely delivers heat pipes for terrestrial electronics cooling copper water on orbit satellite thermal management aluminum ammonia and copper water and high. Electronics cooling is one of the media sponsors and will have an exhibit booth stop by to say hello pick up some literature and chat with us to learn more about what is hot in the electronics industry and how it is so cool to work on thermal management.
Heat pipes for electronics cooling when the heat pipe must in the number of u s. Heat pipes have been commercially available since the mid 1960 s. For example figure 2 shows heat pipe systems that are in high volume production. The vapor then travels along the heat pipe to the cold interface.
The purpose of this article is to explain basic heat pipe operation review key heat pipe design issues and to discuss. Perhaps the best way to demonstrate the heat pipes application toelectronics cooling is to present a few of the more common examples. Due to the limited space and power availablein. Only in the past few years however has the electronics industry embraced heat pipes as reliable cost effective solutions for high end cooling applications.
The 35th semiconductor thermal management conference starts in a week and is being held in silicon valley ca. Today heat pipes are used in a variety of applications from space to handheld devices that fit in your pocket. By george meyer celsia inc. At the hot interface of a heat pipe a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface.
Heat pipes are one of the most efficient ways to move thermal energy from one point to another. Act manufactures a large variety of heat pipes heat pipe heat sinks and heat pipe assemblies for a wide range of applications. Mobile to embedded computing and server type applications with power dissipation ranging from 15 w to 150 w using processor die sizes between 10 mm and 30 mm square. This article is intended to offer design guidance when using heat pipes for the most prevalent types of electronics applications.
In the broader electronics cooling industry heat pipes have been effectively applied as a means to extend the application window of passively cooled heat sinks through heat spreading enhancement.
