Gas steam generator with radially changed pipe diameters at evaporation ends

Abstract

The invention provides a gas steam generator. The gas steam generator comprises a water tank and a heat pipe, wherein the water tank comprises a water inlet and a steam outlet, the heat pipe comprisesvertical parts, horizontal parts and a plurality of vertical pipes, the bottom ends of the vertical parts are communicated with the horizontal parts, the lower parts of the horizontal parts are communicated with the vertical pipes, the vertical pipes are the evaporation ends of the heat pipe, the vertical parts are condensation ends of the heat pipe, the vertical parts extend into the bottom of the water tank, the vertical pipes and the horizontal parts are arranged in a gas burner, and the diameters of the vertical pipes are gradually reduced in the radial direction from the center of the burner to the outside. The diameters of the vertical pipes are different in different positions of the burner, so that the temperature of the whole heat pipe is kept basically the same, then the overallheat exchange efficiency is improved, materials are saved, local damage caused by uneven temperature is avoided, and the service life of the heat pipe is prolonged.

Description

Technical field [0001] The invention relates to an evaporator technology, in particular to an evaporator of a heat pipe with a new structure. Background technique [0002] Heat pipe technology is a kind of heat transfer element called "heat pipe" invented by George Grover of the Los Alamos National Laboratory in the United States in 1963, which makes full use of the principle of heat conduction and phase change medium The rapid heat transfer properties of the heat pipe can quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds the thermal conductivity of any known metal. [0003] Heat pipe technology used to be widely used in aerospace, military and other industries. Since being introduced into the radiator manufacturing industry, people have changed the design thinking of traditional radiators and got rid of the single heat dissipation mode that relies solely on high-air-volume motors to obtain better heat dissipation. The use of ...

Problems solved by technology

The current evaporator is also widely used in the treatment of various diseases, especially in the treatment of chronic diseases caused by aging and old damage such as muscles and ligaments, such as the CN2167709Y patent, but in the current prior art, such as the CN2167709Y patent , because the steam generated directly by heating will cause the temperature of the generated steam to be too high, and it will cause too much moisture in the generated steam, and the drug may be deposited in the lower part because it is a particle, so the active ingredient in the ejected steam The content is too low, and the temperature is too high, and the degree of intelligence in the existing technology is not high, and effective intelligent operation cannot be carried out

[0005] In the prior art, when the heat pipe is used in the evaporator, the shape of the heat pipe affects the heat absorption area of ​​the evaporation end, so the heat absorption range of the evaporation end is generally relatively small, and sometimes multiple heat pipes need to be installed in the heat source to satisfy the heat absorption area. demand; and when there are multiple heat pipes, each heat pipe will have uneven heat absorption due to the different positions of the burner
