Heat tube

Abstract

The invention provides a heat tube which comprises a metal tube, wherein the metal tube is sealed in two ends and is hollow; a work fluid is filled in the metal tube; a plurality of grooves extending along the length direction of the metal tube are formed in the inner wall of the metal tube; a metal net formed by mutually intersecting and knitting a plurality of metal bundles is sleeved in the metal tube; the metal net is formed by arranging a plurality of metal wires in parallel; and an elastic part is sleeved in the mesh net and applies an outward elastic force to the metal net, so that the mesh net is tightly attached to the inner wall of the metal tube. According to the heat tube disclosed by the invention, each metal bundle of the metal net is formed by arranging a plurality of metal wires in parallel; a plurality of fine groove grains formed by treating are formed on all or part of metal wires of each metal bundle; and the fine groove grains extend along the length direction of the metal wires. Each metal bundle contains a plurality of metal wires, so that reflowing channels of the metal bundle are increased; and particularly, the fine groove grains are formed on the metal wires, so strong hydrophilicity and water retention property can be realized, and the dry combustion can be avoided.

Description

technical field [0001] The invention belongs to the technical field of heat conduction, and in particular relates to a heat pipe. Background technique [0002] The heat pipe can rely on the phase change of its internal working liquid to realize rapid heat conduction, has extremely high heat conduction efficiency, and is widely used in various fields that require efficient heat dissipation. [0003] A conventional heat pipe is mainly a closed metal tube with a groove in the tube and a capillary sintered structure near the groove, and an appropriate amount of working fluid is injected into the tube. When used with a heat source, the heat of the heat source is transferred to one end of the heat pipe, and the working fluid in the pipe absorbs heat and vaporizes. The steam flows to the other end of the heat pipe at a high speed under the action of the pressure difference, and releases latent heat after encountering the cold source. Under capillary action, the groove and capillar...
