The heat pipe Type C has two layers of 50-mesh wick. The three kinds of heat pipe containers are all made of SUS316L steel pipes of 25.4mm in diameter and 1000mm in length. The container of the heat pipe Type A is 3.0mm in thickness, whereas the one of the heat pipes of Type B and Type C is 1.5mm in thickness respectively.Heat Pipe Design and Modeling - Heat Pipe Manufacturer Heat Pipe an overview ScienceDirect TopicsHeat pipes are passive, two-phased heat transfer devices, using liquid to vapor phase transition to provide minimal temperature rise across their length. A typical copper water heat pipe will operate with a two to five degree temperature difference. And that rule of thumb is a general basis for a lot of the modeling well dive into later.Heat Pipe Seminar Presentation PPT - SlideShareSep 18, 2016 Heat exchangers- power industries use heat pipe heat exchangers as air heaters on boilers.

NASA - Keeping Cool With Heat Pipes on the Space Station

A heat pipe is a simple device that can efficiently transfer heat from a hot spot to a cooler remote location without the use of a mechanical pump. To further insights into the operation of a heat pipe in space, scientists launched an investigation called the Constrained Vapor Bubble, or CVB, to the International Space Station.Oscillating Heat Pipes ThermAvant TechnologiesOscillating Heat Pipes (OHPs) use thermally driven, two-phase fluid flow to rapidly transfer heat between heat sources and heat sinks.
