Solar steam generator with changing heat dissipation end annular distances

Abstract

The invention provides a solar steam generator. The solar steam generator comprises a reflector and a steam pocket located at the focus position of the reflector. The reflector reflects solar energy to the steam pocket for heating water in the steam pocket. The solar steam generator is characterized in that a heat pipe is arranged in the steam pocket and comprises a header and heat dissipation ends, the header is arranged at the bottom of the steam pocket, the heat dissipation ends communicate with the header, and the heat dissipation ends start to extend upwards from the upper portion of theheader, the multiple heat dissipation ends are arranged, and in the outward radial direction of the center point of the upper wall face of the header, the pipe diameters of the heat dissipation ends are gradually reduced. The novel solar steam generator of a heat pipe structure is provided, the whole heat pipe temperature is kept basically the same through the heat dissipation end pipe diameter changes, accordingly, the integral heat exchange efficiency is improved, materials are saved, local damage caused by the uneven temperature is avoided, and the service life of the heat dissipation endsis prolonged.

Description

technical field [0001] The invention relates to a steam generator technology, in particular to a steam generator of a heat pipe with a new structure. Background technique [0002] Heat pipe technology was developed in Los Alamos, USA in 1963. national laboratory A heat transfer method called a "heat pipe" invented by George Grover element , it makes full use of the principle of heat conduction and the rapid heat transfer properties of phase change media, and quickly transfers the heat of the heating object to the heat source through the heat pipe, 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 t...

Problems solved by technology

The current steam generator is also widely used in the treatment of various diseases, especially in the treatment of chronic diseases caused by aging and old damage to muscles and ligaments, such as CN2167709Y patent, but in the current prior art, such as CN2167709Y Patent, because the steam is generated directly by heating, the temperature of the generated steam will 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 ejected steam is effective The content of ingredients 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 background technology, when the steam generator is heated by solar energy, the solar energy either directly heats the steam drum, or generates steam through secondary heat exchange, especially directly heats the steam drum, and utilizes the convective heat exchange inside the steam drum to heat the upper and lower parts of the steam drum. The convective heat exchange of the fluid, but in this case, the lower part of the hot fluid needs to be naturally convected to the upper part, and the heat transfer efficiency is low
