A heat pipe steam generator for producing liquid medicine

Abstract

The invention provides a heat pipe steam generator. The heat pipe steam generator comprises a water tank and a heat pipe, wherein the water tank comprises a water inlet and a steam outlet, and the heat pipe comprises a first vertical part, a horizontal part and a second vertical part; the bottom end of the first vertical part communicates with the horizontal part, the lower part of the horizontalpart communicates with a plurality of vertical pipes, the second vertical part is an evaporation end of the heat pipe, the first vertical part is a condensation end of the heat pipe, the first vertical part extends into the bottom of the water tank, and the second vertical part and the horizontal part are arranged in a heat source; and the first vertical part is composed of the multiple condensation pipes extending to the bottom of the water tank, and the lengths of the parts, extending to the water tank, of the condensation pipes are smaller and smaller in the flowing direction of the flue gas. According to the heat pipe steam generator, the lengths of the parts, extending to the water tank, of the condensation pipes are set to be different at different positions of the flue gas channel,so that the heat absorption capacity of the condensation pipes is continuously reduced in the flowing direction of the flue gas to be adapted to the heat absorption capacity of the vertical pipes, then the temperature of the whole heat pipe is kept basically the same in the flowing direction of the flue gas, therefore, the overall heat exchange efficiency is improved, the 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 a heat pipe 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 ob...

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 evaporating ends, each evaporating or condensing end will have uneven heat absorption due to the different positions of the heat source or cold source
