Heat pipe, manufacture method and special equipment

Abstract

The invention belongs to the technical field of heat conduction, particularly to a heat transferring heat pipe for conducting out heat energy from a furnace body or a heat source in industries such as power generation, chemical engineering, metallurgy and the like, a manufacture method and special equipment. The invention has the main technical scheme that the method comprises the following steps: adopting a container which is provided with holes in the center position and arranged at the middle part of a fixed frame; placing primary glaze materials formed by adding water into silicon dioxide, potassium oxide, boron oxide, sodium fluorosilicate, aluminum oxide, disodium oxide and calcium fluoride into the container; pulling a pipe tube by a traction mechanism for forming slurry to be calcined and formed into a primary glaze layer; then, repeating the steps for adding water into the silicon dioxide, lithium oxide, disodium oxide, potassium oxide, aluminum oxide, nickel oxide and manganese oxide to be stirred for forming glass materials to form slurry on the pipe tube calcined with the primary glaze layer; and preparing the materials into the heat pipe through calcinations. The heatpipe can effectively avoid the corrosion of corrosive gas, and has the characteristic of long service life.

Description

technical field [0001] The invention belongs to the technical field of heat conduction, and relates to a heat transfer heat pipe used in power generation, chemical industry, metallurgy and other industries to export heat energy from a furnace body or a heat source, a manufacturing method and special equipment. Background technique [0002] The heat pipe is used as a conduction and heat dissipation mechanism of the heat source. Its structure includes a tube tube with both ends sealed. A certain amount of working fluid is installed in the tube tube. One end of the tube is inserted into the heat source to heat and absorb heat energy. The phase change of the internal working fluid realizes heat transfer. function. The structure of the heat pipe currently in use includes a light pipe and a finned pipe, that is, a light pipe made of a tube with a smooth outer wall made of metal material, and a heat pipe arranged on the outer wall of the tube in order to increase the heat transfer ...

Problems solved by technology

However, the heat pipes of these two structures have the following defects in the use process and the manufacturing process: First, the heat pipes composed of smooth tubes and finned tubes are directly inserted into boilers or other heat sources, and because they contain a large amount of corrosive gases and dust Particles, so the heat pipe is easily corroded, oxidized and eroded by particles, which greatly shortens its service life; secondly, the new finned tube does increase the contact area and improve the heat transfer efficiency, but in the process of use due to ring or spiral It is very easy to store dust between the shaped fins. In order to reduce the impact of stored dust on the heat conduction efficiency of the heat pipe as much as possible, the dust in the fins must be continuously removed, which will cause interruption of heat conduction, thereby reducing the use of the heat pipe to achieve heat conduction.
