Density-changeable heat pipe solar loop heat pipe system for purifying soil by microorganism

Abstract

The invention provides a density-changeable heat pipe solar loop heat pipe system for purifying soil by microorganism, The density-changeable heat pipe solar loop heat pipe system comprises a solar device and a loop heat pipe device, wherein the solar device comprises a solar heat collector and a heat exchanger, the loop heat pipe is a counter gravity heat pipe, the loop heat pipe comprises an evaporation end and a condensation end, and the condensation end is arranged on the outer wall of a gas chamber; the gas chamber is arranged in soil along the height direction from the upper part to the lower part, and the winding density of the condensation end of the loop heat pipe in the outer wall of the gas cavity becomes larger and larger. Through the change of the winding density of the condensation end, heat is concentrated to the lower part as much as possible to carry out heat exchange, because the temperature of the lower part is low, more heat is needed, and the soil repairing effect is enhanced, and therefore, the overall repair is uniform; and experiments show that the repair effect can be further improved by around 11% by virtue of the structure.

Description

technical field [0001] The invention relates to the fields of solar energy and heat pipes, in particular to a solar loop heat pipe system for microbial soil purification. 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 ...
