Solar loop heat pipe system with highly changed heat pipe pipe-diameter for microbial soil purifying

Abstract

The invention provides a solar loop heat pipe system with a highly changed heat pipe pipe-diameter for microbial soil purifying. The 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 heat exchanger is connected with the solar heat collector; a fan is used for inputting air into the heat exchanger; after air is heated into hot air in the heat exchanger, the hot air enters the loop heat pipe device; the loop heat pipe device comprises an air inlet channel, an air outlet channel, aloop heat pipe and a gas chamber; the loop heat pipe is an anti-gravity heat pipe; the loop heat pipe comprises an evaporating end and a condensing end; the condensing end is arranged on the outer wall of the gas chamber; the gas chamber is arranged in soil; and the pipe diameter, on the outer wall of the gas chamber, of the condensing end of the loop heat pipe is gradually increased in the heightdirection from the upper part to the lower part. The pipe diameter of the condensing end changes for concentrating heat on the lower part as much as possible for exchanging heat; and the next-step temperature is low, so that more heat is needed, and therefore, the soil restoration effect is strengthened, and the integral restoration is uniform. According to the experiment, about 11% of the restoration effect further can be improved through the structure.

Description

Technical field [0001] The invention relates to the field 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 kind of 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. Fast heat transfer properties, the heat of the heating object is quickly transferred to the heat source through the heat pipe, and its thermal conductivity exceeds the thermal conductivity of any known metal. [0003] Heat pipe technology used to be widely used in aerospace, military and other industries. Since being introduced into the radiator manufacturing industry, people have changed the design thinking of traditional radiators and got rid of the single heat dissipation mode that relies solely on high-air-volume motors to obtain better heat ...
