A solar steam generator with a square header heat pipe structure

Abstract

The invention provides a solar steam generator. The solar steam generator comprises a reflector and a steam pocket, wherein the steam pocket is positioned at the focal point of the reflector, the reflector is used for reflecting solar energy to the steam pocket and is used for heating water in the steam pocket, and a heat pipe is arranged in the steam pocket; the heat pipe comprises a header and heat dissipation ends; the solar steam generator is characterized in that the number of the heat dissipation ends is multiple, the bottom of a collection box is connected to the inner wall of the steampocket, and the heat dissipation ends are of a square structure; and the heat dissipation ends are annularly distributed at the center point of the wall surface of the upper part of the collection box. According to the solar steam generator with a novel heat pipe structure, due to the fact that the square heat pipe is arranged at the bottom of the steam pocket, the heat transfer speed of the solar energy is increased through the characteristic that the heat transfer speed of the heat pipe is high, and the heat absorption capacity can be further met.

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

During the evaporation process of the heat pipe, it will inevitably carry liquid to the steam end. At the same time, because of the exothermic condensation of the condensation end, there will be liquid in the condensation end, and the liquid will inevitably mix with the steam, so that the fluid in the heat pipe is vapor. Liquid mixture, the existence of vapor-liquid mixture causes the gas to mix together, and the heat exchange capacity between the liquid and the liquid decreases, which greatly affects the heat exchange efficiency
