Hybrid heat pipe

Abstract

There is disclosed a heat transferring device comprising a number of spaces and conduits together with heat transferring elements and a heat exchanger as well as a heat source. A capillary tube feeds a heat transferring medium to a space from which is can be evaporated. The invention is highly suitable for all applications where heat is to be transferred from a small volume to a large area. It is also suitable where the same large area needs to be cooled. The energy consumption is reduced compared to more traditional technologies. The number of moving parts is minimized which gives lower costs for use, manufacture, maintenance etc. The invention is very versatile and can be utilized in many different applications where it is desired to transfer heat from one point to a large area. It can also be used for cooling purposes.
