A gas evaporator with radially changing distribution density at the evaporating end

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 extends into the bottom ofthe water tank, and the vertical pipes and the horizontal parts are arranged in a gas burner. The distribution densities of the vertical pipes are gradually reduced in the radial direction from the center of the burner to the outside. The distribution densities of the vertical pipes are different in different positions of the burner, so that the temperature of the whole heat pipe is kept basicallythe same, then the overall heat 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 a heat pipe evaporator with a new structure. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and phase change medium. The rapid heat transfer properties of the heat pipe quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables the radiator to ...

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
